Beschreibung des für die Gebrauchsmustereintragung1 bestimmten Gegenstandes: Angelder: Poter Draheiin 4 Düsseldorf Dreifaltigkeitsstr. 16 Die Bezeichnung des Gegenstandes istJ "In Kunstharz eingegossenes Radio". Beschreibuni-,: Ein Transistorradio, weiches entweder frei schweb end an einem Drahtgestell aufgebaut ist, oder auf einer transparenten Kvaast-■ stoff platine montiert ist, wird in transparent ein Kunstharz eingegossen. Die entstehende Wärme beim Abbindeprozess des Kunstharzes wird durch Kühlung verringert, so daß das Transistorradio seine Funktion behält. Die Stromversorgung des Gerätes erfolgt entweder durch eine mit eingegossene wiederaufladbare Batterie mit Selen- bzw· Siliziumzellen u;ier über vorgesehene miteingegossene Klemmen oder Buchsen. Der Lautsprecher wird nach Aushärtung und anschließender Polierung des Kunstharzblockes in eine vorgesehene KuIde angeschlossen und fest eingefügt. Die Abstimmung auf verschiedene Empfangsfrequenzen wird durch Drehen der Spulenkerne im frequenzbestimmenden Teil oder durch Veränderung der Lage mit Quecksilber schaltern vorgenommen. 7">as Gerät kann mit einem Quecksilberschalter an- und ausgeschaltet werden. Das transparent-eingegossene Transistorradio soll die Funktion dieses Gerätes veranschaulichen.

Description: A transistor radio, which is either set up freely floating on a wire frame, or is mounted on a transparent plastic ■ board, is encased in a transparent synthetic resin. The heat generated during the setting process of the synthetic resin is reduced by cooling, so that the transistor radio retains its function. The device is supplied with power either by a cast-in rechargeable battery with selenium or silicon cells or via clamps or sockets that are cast in with it. After curing and subsequent polishing of the synthetic resin block, the loudspeaker is connected to a given KuIde and firmly inserted. The coordination to different reception frequencies is made by turning the coil cores in the frequency-determining part or by changing the position with mercury switches. 7 "> he device can be switched on and off with a mercury switch. The transparent-cast transistor radio is intended to illustrate the function of this device.
