Patent DE-2839980-A1 (DE)
Title: Cine camera interlock - between main key and trigger through silicone oil coated brake disc
Inventor: SCHROEDER KLAUS
IPC: G03B17/38
Filed: 1978-09-14
Abstract: In a cine camera, the function of the main key in the handle and of the trigger key are interlinked in such a way that the trigger key cannot switch ON the film drive before all essential cameral functions (exposure automatic, sound recording automatic etc.) are ON. Before a shot ends, the main key switches the functions OFF only after the film drive has come to a standstill. This is achieved by a disc brake which couples the functions by a rectangular lug on the disc during the starting period. During the finishing period, a delay in its action is achieved by a silicone oil film on the two faces of the friction discs of the brake. The viscosity of the silicone oil used remains constant between -15 degrees C and +60 degrees C. The delay time of the brake ensures that no film is wasted by the main key acting too late at the start or cutting out too soon at the end.

Title: High speed train extended stator motor switching circuit - has detachable three=phase travelling field-shaft winding on track fed via rectifier
Inventor: VEGELAHN FRITZ
IPC: B60L13/00
Filed: 1978-12-06
Abstract: The circuit is for an extended stator motor, in partic. non-iron construction for conductor guided high speed trains, containing a translator with an induction coil. On the track is a detachable, three-phase travelling-field-shaft winding, fed via a rectifier. The travelling-field winding (1) is located in the track path at set points on the track, corresp. to the controllable star-point connections (12), which depend on the passage of the motor-driven vehicle. The direction of travel can be switched and is affected through the active-travelling field winding. The active winding length, via the switchable star-point connections (12) is shortened, stepwise, w.r.t. the decreasing voltage drop, at the onset of travel, at which the upper voltage limit of the rectifier (2) is attained from the resulting fall in voltage.

The analog memory, an intermediate memory, a gate circuit and an adder are all located on the same substrate, which is made of p-type silicon with an aluminium layer on its oxide layer. The MOS capacitors are separated from one another by etching columns into the aluminium. A charge-coupled-device chain circuit has beneath the intermediate memory. The advantage lies in simple manufacture.
Patent DE-2904897-A1 (DE)
Inventor: KOCH WOLFGANG
IPC: A47F5/00
Filed: 1979-02-09
Abstract: The display stand (1) having receiving containers (4) mounted rotatably thereon is designed for receiving the articles (12) to be displayed. The receiving containers (4) each have a base plate (5) with grooves for inserting partitions (10, 10a). The connection of the base plate (5) to the partitions (10, 10a) to form the receiving containers (4) is thus simplified. A very sturdy connection of the base plate (5) to the partitions (10, 10a) is thus produced at the same time. Additionally, the junctions between the base plate (5) and the partitions (10, 10a) are thus predetermined so that simple assembly is also possible. This also allows a further development with a plurality of grooves for arranging further partitions, by means of which the receiving container (4) can be subdivided into individual receiving compartments. To improve the stability of the articles (12) to be displayed, the base plate (5) can have beads (18) as stops on the outer longitudinal sides, said beads projecting beyond the surface of the base plate at least in some places. Even if the rotary stand is rotated rapidly, there is virtually no risk of an article to be displayed dropping laterally out of its removal opening. <IMAGE>
