IPC: A61K6/90
Filed: 1987-07-30
Abstract: Application of an inert, skin-compatible, free-flowing hydrocolloid to parts of the surface of the human skin or to wounds results, after solidification, in a negative mould which detaches very easily from the skin. Application of a methyl methacrylate produces from the resulting negative mould a glass-clear positive impression of high accuracy which can be examined and photographed under the transmitted- and reflected-light microscope. After the positive impression has been vacuum-coated with an electrically conducting layer it is also possible to carry out scanning electron microscopic examinations and photographs of the impression of the vital skin surface.
Patent DE-3731115-A1 (DE)
Title: Traversing device
Inventor: BARTKOWIAK KLAUS
IPC: B65H54/28
Filed: 1987-09-16
Abstract: The invention relates to a traversing device in a winding machine for a thread, in which the thread guide is moved to and fro in a straight line between the stroke ends. To recover the energy of the thread guide, movable masses are arranged at a fixed location in such a way that they intersect the path of the thread guide or of a part moved together with it. The thread guide or the part moved together with it cooperates with the movable mass along a slotted guide. This ensures that the energy of the thread guide released during braking sets in motion the mass which itself, after the stroke end has been exceeded, returns the intermediately stored energy to the thread guide for the re-acceleration of the latter.

Title: Safety circuit for engine-independent vehicle heaters
Inventor: HAMMER MICHAEL DIPL ING
IPC: F24H9/20
Filed: 1987-11-14
Abstract: The safety circuit for engine-independent vehicle heaters serves as additional safety against cases of overheating if separate drives are used for feeding combustion air and conducting away heat. With this safety circuit, operational safety is to be increased. It is to be possible to switch on the heat-conducting drive in the starting phase with a time delay with respect to the ignition device, fuel feed and combustion air feed and the fuel feed is to be disabled if no current flows when a voltage is applied. The object is achieved in that a coil with magnetic core is inserted in the circuit of the motor serving to conduct away heat, the field lines of which coil are evaluated by a Hall circuit. The output of the Hall circuit is connected via a diode to the switching line of the engine to be monitored, to the control component of the heating device and via a resistor to the stabilised voltage. <IMAGE>

Patent DE-3840699-A1 (DE)
Title: Switching mechanism for protective switching devices (switchgear)
IPC: H01H71/52
Filed: 1988-12-02
Abstract: This device copes with short-circuit currents up to approximately 100 A exclusively by the kinetic energy of the switching mechanism. The rated current of the switching device is irrelevant in this case.   For this purpose, a powerful force store is necessary which is completely isolated from the contact system when the switching device is in the connected position. At the same time, different contact forces have been prevented from being transmitted to the latch, and there are likewise no release scatters. This invention ensures that the kinetic energy of the switching spring acts suddenly on the moving contact, via the toggle lever and without any delay, after unlatching. This invention achieves the object of ensuring low unlatching forces with little scatter for the automatic release and, at the same time, irrespective of contact erosion and of the short-circuit current in this case, of applying a powerful mechanical impact effect in the opening direction to the moving contact.
