Title: Method of producing zinc powder for alkaline batteries by atomisation
Inventor: GLAESER WOLFGANG DR ING
IPC: H01M4/42
Filed: 1982-10-15
Abstract: The invention relates to a method of producing zinc powder having a mercury content of 0.1-10% by weight and, optionally, further alloying elements for use in alkaline batteries by atomisation. A slightly overheated melt of zinc or a zinc alloy is introduced into mercury or a mercury/zinc master alloy, homogenised, atomised and mixed with an amount of water which is such that the latter evaporates as a result of the heat content of the powder particles. This produces a better and more homogeneous product under more environmentally acceptable conditions than hitherto.

Title: Actuator for a photographic lens
Inventor: HOEPFNER CLEMENS
IPC: G02B7/08
Filed: 1983-01-14
Abstract: An electronic switch controlled by a focus-determining device periodically feeds a DC motor for the lens actuator. Arranged in the gear train of the actuator is a drive switching mechanism which can be reversed in direction and has a rotary drive driven by the DC motor. If the lens has reached the focusing position, the motor feed is cut off. As a consequence of switching off the motor in phase with reference to predetermined positions of the drive switching mechanism, its deceleration phase falls in the dwell phase of the drive switching mechanism, so that no further actuating forces are transmitted to the lens. <IMAGE>

Filed: 1983-02-01
Abstract: The battery isolator switch according to the invention has a handle for random switching on and off, having a rotation axis which has studs projecting on both sides and can be inserted into a sleeve which is provided with helically running guide slots. A contact supporting bolt with a restoring spring is guided into the switched-on position by a rotary movement of the handle. In the limit position of its studs at the end of the guide slots, the handle is held in a self-locking manner. It can be moved back by initiating a rotary movement in the opposite rotation direction, releasing the restoring spring, which also opens the isolator switch contacts. At least one of the two studs, which may be formed by a lateral pin in the shaft of the handle, projects so far through the sleeve wall that it can be acted on by a force source, for example an explosive cartridge, and initiates the rotary movement of the handle in the switching-off direction. The force source can be initiated by a pulse, as a function of the triggering of a fire detector.

Patent DE-3314309-A1 (DE)
Title: Variable ring-gear mechanism
Inventor: KUGLER HERMANN-JOSEF
IPC: F16H1/20
Filed: 1983-04-20
Abstract: In the case of motor vehicle gear mechanisms, the power flow takes place by means of at least three gear engagements (gear-shift mechanism, change-speed gear mechanism, differential gear mechanism). Only in the case of a passenger car does the power transmission in the highest gear take place directly from the engine shaft to the ring gear in the driving axle. Since, according to the invention, one or more ring gears are likewise used for speed variation, the shift-gear mechanism or change-speed gear mechanism are unnecessary. Because an overdimensioned ring gear does not impair the ground clearance in the case of tracked vehicles, here the entire gear-shift and change-speed gear mechanism can be replaced by a variable ring-gear mechanism. The variable ring-gear mechanism is suitable not only for motor vehicle gearboxes, but also for any drive technology where the direction of power has to be developed (for example power take-off machines). It is not only important to design engines with high efficiency but also to transfer the power with the least possible losses. The variable ring-gear mechanism is one of the inventions which saves considerable energy with little expenditure. The higher the efficiency, the less the environmental pollution.
