Patent DE-2649895-A1 (DE)
Title: Photoresistor trigger for cine camera film drive - uses shutter blade to control light striking photoresistor and balance comparator circuit preventing exposure when light level is too low
Inventor: WAGENSONNER EDUARD ING GRAD
IPC: G03B19/18
Filed: 1976-10-29
Abstract: The cine camera motor is switched by the shutter blade so that film is not used when light levels are unsuitable. Light striking a photoresistor causes an imbalance in a comparator circuit controlling the shutter blade drive motor. The shutter blade is driven to control the light striking the photoresistor and balance the comparator circuit but, as a determinable light level, an abutment on the blade opens a switch to disconnect the circuit to the film transport motor. Reconnection of the film drive motor circuit follows automatically.

Title: Accelerator pedal setting control - has holding electromagnet set by switch on dashboard and released by microswitches operated by brake and clutch pedals
Inventor: HASENFUSS ROBERT
IPC: G05G1/46
Filed: 1976-11-08
Abstract: The throttle linkage incorporates a pivoted lever (1) set over an electro magnet (2) held on a spring mount (3). The magnet is activated by a switch on the dashboard when the selected speed is reached. Microswitches on the brake and clutch pedals de-activate the electromagnet to reset the throttle to idling. The throttle pedal can be operated to override the setting so that a higher speed can be set. The electro magnet automatically clamps when the pedal is released.
Patent DE-2653486-A1 (DE)
Title: Fixing toner image in two stages - first rapid stage on electrically heated belt and second radiant stage
Inventor: EPPING REINHOLD H DR
IPC: G03G15/20
Filed: 1976-11-25
Abstract: Electrophotographically produced images, which have been developed by toner powder contg. thermoplastics substances, are developed by placing the image support on an electrically conducting conveyor belt and heating the belt rapidly by passing current through it to just below the fusion point of the toner, at the same time intensively agitating the support sheet together with the belt to promote contact heating. The support then passes through a limited area where it is subjected to radiant heat to bring it up to the desired fusion temperature for the powder, precautions against overheating being taken. Pref. the conveyor belt is silicone coated. The fixing takes place very rapidly, so that a relatively long heating-up time for the machine of several minutes is not necessary. Also, it is no longer necessary to keep the machine hot in preparation for developing and fixing in order to avoid this delay.
Patent DE-2653876-A1 (DE)
Title: Heater for indoor swimming pool and hall - uses hot air generator providing air utilised also for heating water used only for short periods
Inventor: KRAEMER KLAUS
IPC: F24D5/00
Filed: 1976-11-26
Abstract: The heater for heating hall air and pool water is used for indoor swimming pools. Part of the hall air is heated and circulated by the hot air generator.

This arrangement can be used for a pool used only for short periods, esp. only for a few hours in any day. The pool is covered with floating foil for preserving heat. The hall air is not heated when the pool is not in use.

Title: Camera with electronic flash - has iris diaphragm values indicated by weather and distance marks interchanged by switch
Inventor: EDAMOTO AKIO
IPC: G03B17/18
Filed: 1977-03-21
Abstract: The shutter speed is fixed and the opening of an iris diaphragm alone is variable. Values of the iris diaphragm opening are indicated by pictures so that an appropriate value can easily by selected. Pictures include two kinds, namely pictures of weather marks indicating the weather condition and pictures of distance marks indicating the distance to an object to be photographed. These picture marks are interchanged by "on" and "off" operations of a switch of a power source of the installed electronic flash. When the switch is put off, weather marks alone can be seen, and when the switch is put on, distance marks alone can be seen.

Title: Thyristor controlled welding circuit - with better welding parameters by hyperbolic voltage-current characteristic
Inventor: NICKEL ERICH
IPC: B23K9/10
Filed: 1977-05-12
Abstract: Circuit for a thyristor-controlled welding rectifier, based on the current slicing principle, has a hyperbolic U-I characteristic. The gradient DELTA U/DELTA I is greater in the lower current region when the current slicing has affected most of the sinusoidal phase, than at high loads. This has been achieved by designing the inductance of a choke coil or o f leakage flux core accordingly. Arrangement gives optimum welding conditions both at full load and at low load. The short-circuit current is limited and the welding operation is free from sputter. A separate damping or smoothing choke coil in the d.c. circuit can be saved.
Patent DE-2721908-A1 (DE)
Title: Extended control of ball symbol for TV game - has AND=gate and RS flip=flop giving single player exclusive control for set period
Inventor: ZECH RONALD DIPL ING
IPC: A63F13/40
Filed: 1977-05-14
Abstract: Electronic ball games can be displayed on a TV Screen, and include one symbol for the ball and also a separate symbol for each player. Each player can in turn contact the ball symbol in order to influence its movement as it approaches the playing partner. To increase the ball control for each player, the influence on the ball symbol after contact is extended. Thus the speed or flight path of the returned ball symbol can be varied for a short time after contact. During that time, the ball control signals from the opposing players are ineffective. The system uses a logic circuit with two AND gates (5, 6) an RS flip-flop, and an output circuit with two further AND gates (8, 9) and an OR gate (12).

Application of sealing cpd. can be made before or after the cap is pushed fully home on to the body. The sealing cpd. can be material of the cap or body itself softened by localised heating where sealing is required. Used as a hard-shelled, cylindrical capsule o contains a viscous material, esp. a liq. pharmaceutical compound. A completely leak-proof capsule can be filled without difficulty on the premises of the pharmaceutical mfr.

Title: Flame-actuated fire extinguisher - has plug-forming compound actuating valve controlling extinguisher charge
Inventor: BENDLER HELLMUT
IPC: A62C35/08
Filed: 1977-06-01
Abstract: The cylinder containing the pressurised extinguishing agent is fitted with head (1) screwed into the cylinder. Inside the head a bushing (3) accommodates the end of fuse cord (9) and contans a combustible charge (7). An enlarged section of the head contains cup-shaped part (6) containing a gas producing compound (6). s the flames reach the fuse cord (9) it ignites and after burning in direction of the head finally reaches the combustible charge (7) which it ignites.

Title: Ferrosilicon-nitride purificn. - where treatment with chlorine gas produces high content of silicon nitride and low iron content
Inventor: ERTL ERICH DIPL ING DR
IPC: C04B20/10
Filed: 1977-06-02
Abstract: The Fe-Si-N contains by wt. 80-95% Si3N4 obtd. by the chlorination of Fe-Si-N obtd. in a conventional way. The initial Fe-Si-N powder is reacted at high temp. with Cl2 gas to produce ferric chloride, which is deposited cooled reactors. The chlorination pref. occurs at 200-600 degrees C, esp. 300-550 degrees C., for 20-80 mins. the reaction time and temp. being used to adjust the residual iron content of the purified Fe-Si-N obtd. Fe-Si-N contg. 65-98% Si3N4 is used as a less expensive alternative to Si3N4 in refractories employed e.g. in blast furnaces, but the high Fe content of the conventional material is undesirable. Fe-Si-N with a low iron content is produced at low cost without producing effluents causing pollution.
