Patent DE-3837360-A1 (DE)
Title: Explosive projectile having an impact fuze at the tip
Inventor: BECKER WILFRIED DIPL ING
IPC: F42C19/02
Filed: 1988-11-03
Abstract: The invention relates to an explosive projectile (10) having an impact fuze (12) at the tip. In the case of such projectiles, if the projectile strikes the ground flat, the grazing angle  alpha  being less than the cone angle ss of the fuze housing (12), there is a risk of the screwed-on fuze housing (12) being detached by the severe braking effect on the rearward projectile body (10) and by the torque acting on the fuze housing (12) in this case. To this end, the invention specifies measures to overcome these disadvantages reliably such as, for example, a left-hand threaded screw connection which tightens itself. <IMAGE>

Patent DE-3907261-A1 (DE)
Inventor: EIDENSCHINK RUDOLF DR
IPC: C09J5/00
Filed: 1989-03-07
Abstract: So far, contact or fusion adhesives have been used to make temporary bonds. However, high temperatures or considerable mechanical force are required to release the materials and it is often impossible to prevent damage to fragile materials. The new adhesive is intended for use in the same fields as contact and fusion adhesives and also as a reaction adhesive and is designed to be transformed into a state of low viscosity for the release of the secured material. Instead of polymeric materials, the novel adhesive contains a low-molecular component with liquid-crystal properties which, through the conversion from a low-viscosity to a liquid-crystal phase of higher viscosity, produces a bond between the materials. The adhesive is suitable for the temporary or permanent securing of semiconductor components, wafers or components to be thermally or mechanically processed.
