Patent DE-2502469-A1 (DE)
Title: Charging control circuit for electrical storage heater - monitors motion of timer motor and release of charging start signal
Inventor: BREITBACH HEINER
IPC: G05D23/19
Filed: 1975-01-22
Abstract: The monitoring circuit, for the charging control of an electric storage heater, monitors the position of the electromotor (9) in the timing device and/or the generation of the signal that starts the heater charging process. The timing device triggers the start signal when it reaches the preset switch-on time for the heater. If the monitor detects a fault in either of these two monitored parameters it automatically switches off the heater. The monitor is supplied from the same supply voltage as the central control unit and can simultaneously monitor the operation of that central control unit.

Title: Sealing cylinder in motor air gap - made from highly oriented ferritic material to inhibit leakage fluxes
Inventor: MASUMOTO KATASHI
IPC: H02K5/132
Filed: 1975-06-27
Abstract: In motors operating in hostile environments, for example for pumping corrosive substances, it is the practice to isolate the stator windings (4, 5) from the rotor (6) by a cylinder (2) in the air gap (8) with suitable seals at each end. In order to attain the more efficient operation allowed by using a small air gap it is proposed that the permeability in the circumferential direction (b) around the stator bore is very much lower than the permeability in the radial direction (c) across the air gap (8). Thus the effective air gap remains small whilst the circumferential leakage flux is kept to a low value.

Title: IC engine with two or four meshing wheels - has wheel teeth which always contact each other at two points to form an enclosed chamber
Inventor: SENFFTLEBEN UWE
IPC: F01C1/18
Filed: 1976-02-17
Abstract: Internal combustion engine with only two or four toothed wheels as individually moving parts has the teeth so shaped that they always contact one another at two points so that an enclosed chamber is formed which expands or contracts as the wheels rotate. Where four wheels are employed an improved ejection of exhaust gases is achieved. The sides of the teeth therefore act as piston-cylinder units. At the initial point of contact the suction and compression stages arise. When the tooth one wheel is located as far as possible into the inter-tooth gap on the neighbouring wheel ignition occurs and the power stroke commences. As the wheel teeth separate so the exhaust gases are discharged.

Title: Stretch-forming for coach bodywork - clamping strip stretch surface changes from concave to convex with laterally variable radii
Inventor: MAEDE WOLFGANG DR ING
IPC: B21D22/22
Filed: 1976-04-17
Abstract: A stationary clamping arrangement is for relatively smaller workpieces which have to be stretch-formed into a dished shape in both direction. Basically, the arrangement consists of a concave bottom part and a complementary stretch forming rod. The relevant feature of the design is that the stretching surface (8) of the bottom clamping strip (7) changes from concave to convex shape with laterally varying radii and/or that the stretch surface (8) is lower than the highest point of the terminal area of the stretching dye. Material is saved as a result of the diminishing of the sectional dimensions required.

Title: Automatic colour printer exposure control device - with light output being negative logarithmically converted, integrated and balanced to predetermined constant value
Inventor: TOKUDA KANJI
IPC: G03B27/73
