Patent DE-2535859-A1 (DE)
Title: Surface coating of sporting tracks such as skittle alleys - consists of glass fibre reinforced resin underlayer and glass fibre free top layer
Inventor: KLEBER KURT
IPC: A63D1/04
Filed: 1975-08-12
Abstract: In the coating of highly stressed tracks having a hard substrate layer of concrete, asphalt, wood inlay (parquet) a liquid two-component, hardener containing synthetic resin is applied as a thin layer over the substrate layer. 1 layer of glass fibre matting is placed on the still fluid resin layer. A further layer of hardener-treated synthetic resin is then applied in such amount that the glass mat layer is completely impregnated and the hardened resin presents a continuous plane surface. Enables existing skittle or bowling alleys to be restored to competition standard condition, at relatively low cost or new alleys to be built with improved shock-stress and abrasion resistance.

Title: Incidence direction determination system - is for electromagnetic waves and uses different signal delays
Inventor: MEINKE HANS HEINRICH PROF DR
IPC: H01Q23/00
Filed: 1976-03-26
Abstract: An arrangement is for determination of the direction of incidence of an electromagnetic wave.

Title: Safety mechanism for firearm with hammer - has safety block moved between hammer and firing pin
IPC: F41A17/74
Filed: 1976-07-24
Abstract: The safety mechanism is used in a small firearm with a hammer trigger and firing pin. The mechanism ensures that the firearm is ready to fire after cocking of the hammer. However the shot is fired only after actuation of the trigger. Hence the firing of the firearm is entirely dependent on actuation of the trigger (34). An opening is provided in front part of hammer for preventing contact between the hammer and the firing. A block is moved between the hammer and firing pin for safety and for firing. The hammer has components for moving this block so that firing can be carried ouit. This block is normally pushed into the safety position. This block rotates on a lever and the hammer actuated this lever.
