Raw materials, such as powders, are inherently used in the manufacturing industry.
Analysis of such material is often essential prior to use in order to ensure certain characteristics are achieved in the final manufactured product, such as, for example, structural strength and surface finish.
An example of a type of manufacturing in which analysis of powdered material is particularly important is additive manufacturing (AM). Additive manufacturing is the direct fabrication of end-use products and components by depositing material layer-by-layer, without the need for fixed tooling or manual intervention.
Powdered materials for additive manufacturing need to be tested on-site prior to use.
Analysis systems for undertaking such analysis are known. However, the known systems are relatively expensive to buy, maintain and calibrate, and provide a large number and relatively complicated range of test results -many of which are not always required.
It is also a known procedure to send samples of materials to a test laboratory. This procedure has the advantage of reducing capital expenditure, but results in delays and an inability to undertake spot-check analysis of material when required.

The flow aperture 16 is configured and dimensioned such that in a passive mode sample material is retained in the sample container 12.
In an alternative embodiment the sample container 12 may be in the form of a hopper (not shown). The sample container 12, or a part of the sample container, may be detachable from the analysing chamber 14 and removable for cleaning or disposal and replaceable with a new substitute sample container. This is advantageous to prevent cross-contamination of sample materials.
The analysing chamber 14 has a back wall 18 and a front wall 20. Suitably disposed in the front wall 20 is an imaging aperture 22 having an optical element, such as, for example, a macro lens 24.
The analysing chamber 14 also comprises illumination means which includes an illuminating aperture 26, disposed in the front wall 20, and an optical element 28 operable to redirect light along an optical path 29, received into the analysing chamber 14 through the illuminating aperture 26, through 1800 and into optical alignment with the macro lens 24 to provide a back-light.
The optical element 28 may be formed from a pair of mirrored surfaces 30a and 30b disposed on the internal surface of the back wall 18 to face each other at an angle of approximately 900 relative to each other and approximately 45° relative to the internal surface of the back wall 18.
In an alternative embodiment, the illumination means 28 may comprise two optical prisms suitably disposed on the inner surface of the back wall to re-direct the received light through 1800.
The analysing apparatus 10 further comprises attachment means which includes a pair of clips 32a and 32b. The clips 32a and 32b are suitably positioned, dimensioned and spaced apart to securely detachably attach the analysing apparatus 10 to a smartphone 102 (or tablet device)) as described below in relation to Figure 2.
The analysing apparatus 10 is formed from a plastics material. However, it may alternatively be made from other materials depending on, and to suit, other applications.
Referring to Figure 2, an analysing device 100 comprises the analysing apparatus 10 and a smartphone 102 detachably attached to the analysing apparatus 10 using clips 32a and 32b. The smartphone 102 has an image capture device 104, which is a standard smartphone camera, and a flash light-source 106, which is a standard smartphone camera flash.
The clips 32a and 32b can be formed and positioned to attach a specific make and model of smartphone 102, such as, for example, Iphone®, Nokia0 and Samsung0. In doing so, it is important that the clips 32a and 32b are formed in accordance with the dimensions and layout of the specific smartphone with which it is to be used. In this regard, the clips 32a and 32b are dimensioned and arranged to hold the specific smartphone 102 against the external surface of the front wall 20, of the analysing apparatus 10, such that the macro lens 24 and the illumination aperture 26, of the analysing apparatus 10, are optically aligned with the image capture device 104 and the flash light-source 106, of the smartphone 102, respectively.
In an alternative embodiment, the analysis apparatus 10 may be adapted for attachment with a tablet device (for example) an iPad) by suitably forming the clips 32a and 32b in a different arrangement and with different dimensions as appropriate.
In a preferred embodiment, the analysing apparatus 10 comprises a stand 108 for positioning the smartphone 102 in a parallel relationship with the sample container 12 and the analysing chamber 14, and a vertical relationship relative to the surface on which the stand is positioned.
The stand 108 is adapted to at least substantially mitigate external vibration travelling into the analysing apparatus 10, such that the analysis apparatus lOis insulated from external vibration, which may be present on the surface on which it is positioned.
The stand 108 extends from the lower clip 32b and is adapted to provide a platform 112 through which the weight of the analysing apparatus 10, the sample material 110 and the smartphone 102 is distributed to provide stability for improved accuracy during analysis. The stand 108 may be formed from a plastics material and integrally formed with the remainder of the analysing apparatus 10.
An analysing system comprises the analysing device 100 and a computer application (i.e. app) loaded onto the computer readable storage medium of the smartphone 102.
In use, a user loads the sample container 12 with sample material 110 for analysis.
The user then initiates the smartphone app. The smartphone app activates the smartphone vibrator (not shown), which vibrates the analysing apparatus io. vibration of the analysing apparatus 10 causes the sample material 110 to flow from the sample container 12 through the flow aperture 16 and into the analysing chamber 14.
The smartphone app is operable to control the vibration such as to provide a continuous vibration or pulsed vibration) depending on the requirements to agitate the sample material 110 sufficiently to cause it to flow through the flow aperture 16. Also) the smartphone app is operable to alter the frequency and amplitude of the vibration in order to optimize the flow of the sample material 110 through the flow aperture 16. A flow test may need to be undertaken at several different vibration frequencies and amplitudes to reach the optimum flow of material.
The smartphone app also activates the smartphone flash light-source 106) which launches light through the illumination aperture 26, of the analysing apparatus 10. The light travels along the optical path 29 and is thereby re-directed through 180° by the mirrored surfaces 32a and 32b to illuminate and thereby provide a back-light at a predetermined portion of the analysing chamber 14 through which the sample material 110 flows and at which the image capture device 104 captures the required image.
The smartphone app also activates the smartphone image capture device 104, which captures one or more still images and/or a video of the flowing sample material 110, through the macro lens 24. The smartphone 102 therefore interacts with the analysing apparatus 10 to provide the analysing system) which functions as a microscope through which the flow of sample material 110 can be captured and recorded.
The captured images and/or videos are then analysed on-site by the smartphone app to determine one or more characteristics and/or properties of the sample material, such as) for example: the particle/droplet size, the number of particles/droplets per second (i.e. the flow rate)) the speed of particles/droplets.
The sample material is suitably a powder material, which may be, for example) micron metal powders. However, the sample material may be any flowable material such as, for example, sand, soils and liquids, depending on the application required.
Accordingly, the present invention is applicable to many industries such as, for example, manufacturing (especially additive manufacturing), civil engineering, environmental monitoring and pharmaceutical.
The invention is not restricted to the details of the foregoing embodiments, which are merely exemplary of the invention. For example, the shape and configuration of the various elements of the invention may be changed, as might their materials of manufacture.
