Title: Screw-bolt
Inventor: WEISS HERMANN
IPC: G01L5/24
Filed: 1981-09-22
Abstract: The invention relates to a screw-bolt which is designed for an expansion measurement. For this purpose, balls, with their spherical tops projecting out, are clamped in end-side blind bores of the bolt. At least one ball can be pressed deeper into the blind bore for adjustment to a whole unit of length. By means of an external micrometer, the extent of expansion of the screw-bolt can then be determined via a difference measurement before and after expansion. The production outlay of such a screw bolt which is suitable for an exact measurement is lower than for a screw-bolt having end sides which are specially machined, for example on a lathe, for an exact measurement. The balls provide clean bearing points for the measuring equipment (external micrometer) and virtually exclude tilting of the external micrometer when it is fitted thereon. <IMAGE>

Title: Rotary toy
Inventor: LIEKE MICHAEL
IPC: A63F9/08
Filed: 1982-05-05
Abstract: 3-D rotary toys, consisting of rotary bodies which can be turned in relation to one another and which, fastened to holding bodies, run in characteristic guide paths. These rotary bodies are penetration bodies which result from mutually penetrating spheres. These spheres mainly have an identical radius; the sphere centres are mainly in a given relationship with one another, such as e.g. the corner points of a cubic space lattice in the most simple case such as in a cubically primitive space lattice. The number of the mutually penetrating spheres is unlimited according to the extent of the space lattice used as a basis; the form and number of the resulting penetration bodies depend on the space lattice. Arranged mainly on the convex side of the penetration (= rotary) bodies are the fastening bodies which run and are guided in the guide rails arranged mainly on the convex side. The individual rotary bodies can be turned in relation to one another with the guide bodies running in the guide paths so that a certain intelligence is necessary to refind the original arrangement.

Patent DE-3248181-A1 (DE)
Title: Regulating device for an automatic alarm
Inventor: ZUCKER KARL
IPC: E05G1/10
Filed: 1982-12-27
Abstract: To reduce the risk for keyholders of financial institutions and their employees of being exposed, when they are off-duty, to an attack by a criminal for the purpose of opening the safe, the claimed device considerably lessens this risk. This is primarily because the risk for the criminal is increased. Since the criminal cannot ascertain whether the alarm has been or is triggered and also cannot prevent this, an attack on a keyholder has to appear unsuccessful to him. The decision whether the alarm is triggered or not lies solely with the keyholder. As a result of the time delay in opening the lock, the criminal is forced to remain at the scene of the crime for a relatively long time. Because the alarm indication in the event of an alarm is changed to the type described, the police are in the position to assess the situation correctly and to take appropriate measures.
