Title: Encapsulated miniaturised hybrid circuit - has protective coating soft foam buffer and hard outer casing
Inventor: SCHAEFER PETER
IPC: H01L23/31
Filed: 1973-09-19
Abstract: A method of encapsulating in a plastic material miniaturised circuits, esp. hybrid circuits, comprising a dielectric substrate and both active and passive elements, comprises coating the entire circuit, with a protective silicone rubber or lacquer layer, and then encasing in an elastic buffer, esp. of plastic foam, then finally plcig in the plastic material. The benefit of a silicone coating is obtained without the problems arising from differential thermal stresses between the silicone coating and the surrounding plastic casing. The use of a foam buffer accommodates these differential movements. The elastic buffer may be formed by immersing the coated circuit in the foam. After surrounding with the foam, the circuit may have an epoxy resin or silicone rubber casing cast around it.

Title: Balanced trigger for automatically loaded sporting pistol - has firing hammer actuated by levers for constant trigger force
Inventor: CHAIDUROW EFIM LEONTIEWITSCH
IPC: F41A19/44
Filed: 1974-08-16
Abstract: The pistol hammer is held in contact with the one arm of a lever whose other arm is in contact with the trigger intermediate lever when the firing hammer spring is loaded. The actuating force of the trigger contacting hook remains constant for practical purposes before and after the moment of the separation of the lever and the intermediate trigger lever. This arrangement increases the firing accuracy due to the elimination of the variation in the trigger loading. A spring (31) is used to ensure contact of the actuating lever (18) against the hammer lever. One end of this spring is supported against the actuating lever and the other end of this spring rests against the intermediate lever (21). The actuating lever, when the separation takes place, loads the spring (31) with an additional force which compensates the friction forces.
