Abstract
801,603. Reservoir pens. SCRIPTO, Inc. March 22, 1956, No. 9022/56. Class 146(3) In a ball-point pen, ink reservoir tube having a large diameter main portion 16, a small diameter forward portion 12 fitted wit ha ball-point insert 14, and a grease seal which follows the end of the ink column as the ink is used, means is provided to trap all or the major portion of the grease seal at the'forward end of the main portion 16, and to allow the portion 12 to be vented to the portion 16, so that feeding of the ink from the forward portion 12 can be completed on exhaus-. tion of the ink supply from the main portion 16. As shown in Fig. 1, the short forward portion 12 is of capillary size, and is integral with the large diameter portion 16 which is fitted with a vent plug 18. A short tube 20 is fitted into the reservoir to extend into both portions 12, 16, and is provided with one or more slots 22. In operation, when the grease seal, due to the ink being used in writing, reaches the tube 20, a cylindrical section 24 is cut out of the seal and continues to move downwarly into the small diameter portion 12, and the remainder of the seal is trapped exteriorly of the tube 20, as shown at 26. The slots 22 are formed in a -size small enough to prevent flow of the viscous grease seal therethrough, although allowing ready feeding of the ink until the large diameter portion 16 is entirely exhausted. In the construction shown in Fig. 3, the means for trapping the grease seal comprises a plug 110 having an air-vent tube 112 mounted therein to extend some distance into the enlarged portion 106 of the reservoir, and has its end part bent over. This tube 112 provides an air vent that cannot be plugged by the grease seal. and serves to enable complete feeding of the ink in the forward portion 102 when the grease seal 116 is trapped by the plug 110. The plug 110 is formed with longitudinal feed grooves 114 for allowing the passage of ink from the large to the small diameter tube portion, but these prevent the passage of seal grease material. Three other modifications are described and shown. In one, the grease seal is not deformed in the trapping operation. A tube similar to that shown in Fig. 1, but extending the full length of the enlarged portion of the reservoir, is employed, the grease seal sliding down this tube to rest finally on a slotted plug which supports the central tube. In another, the trap plug is conical and has an open end which projects beyond the mass of trapped grease. The third form comprises a segmental plug which traps part of the grease, and allows the other part to follow the ink into the capillary forward portion of the reservoir. The grease seal may comprise a mineral oil having a S.A.E. viscosity of 40, which is bodied with 8 to 10 per cent by weight of aluminium stearate. 801,669. Educational appliances; pictures. BOURNE, J. R. (Hjelt, H. O.), March 26, 1957 [March 29, 1956], No. 9846/56. Classes 11 and 146(2) A process for producing model-pictures for teaching and practising purposes or for making reproductions, consists of velvetizing a glue-coated surface of a picture by means of an electrostatic field. This allows loose fibres to be perpendicularly affixed to a surface which already bears a picture either in monotone or colour, and the velvetization is effected so that the underlying picture remains visible when looked at in a direction longitudinal to the fibres. The contours of the picture which loom under the velvet surface may be followed and strengthened to reproduce the picture on to the velvet surface. An under-picture, which may be in monotone, may be reproduced in colour.
