Title: Device for locking the parts of a drawing head of a drawing machine which are twistable relative to each other
IPC: B43L13/08
Filed: 1981-06-23
Abstract: The stationary sub-member (10) of the drawing head is provided with inward-pointing teeth (108) in its peripheral wall which have obliquely inclined tooth profiles (110). Clamping sections (80) of a locking slide (60) carried by the part-disc (12) of the drawing head interact with these teeth, the inner edges of the clamping sections being inclined in a manner corresponding to the inclination of the tooth profiles (110). The clamping sections (80) are moulded onto a base section (62) of the locking slide (60) via rigid intermediate sections (84) and bending sections (88). The bending sections (88) permit splaying of the clamping sections (80) when the latter are pushed onto the teeth (108) of the sub-member (10) under the force of a prestress spring, but at the same time prevent distortion of the locking slide (60) when external forces and torques are exerted on the drawing head, since in this case the bending sections (88) are stressed to bend and have a high resistance against this loading. <IMAGE>
Patent DE-3126303-A1 (DE)
Title: Water-tightly and air-tightly encapsulated detonator caps
Inventor: GROSSE-BENNE WILHELM A
IPC: F42C19/10
Filed: 1981-07-03
Abstract: For the function of apparatuses where detonator caps are installed, it is necessary that no moisture reaches the priming composition of the detonator cap. Fault-free functioning of the apparatuses containing detonator caps, for example in the case of explosives igniters, is only ensured when the priming composition is completely dry. The object underlying the invention is to create a water-tightly and air-tightly encapsulated detonator cap, where the disadvantages described are reliably prevented. The object is essentially achieved in that the firing side of the detonator cap is air-tightly and water-tightly sealed. Various possibilities suggest themselves here, which can be seen on the accompanying drawing in the examples Figure 1 to Figure 6. The advantage achievable is that the air-tight encapsulation of the detonator cap prevents penetration of moisture into the priming composition and therefore an absolutely reliable ignition, even at extreme temperatures, is ensured. <IMAGE>
