Patent DE-2403503-A1 (DE)
Title: Gapless feeder rail joint - has bridging section with helical surfaces fitted to circular threaded carrier pin rotatingly seated
Inventor: GERICHTEN FRANZ
IPC: B60M1/30
Filed: 1974-01-25
Abstract: Joints on feeder rails should not have gap which cause sparking. The bridging section is provided with a helical-faced element which fits into the complementary helical shapes provided on both ends of the rail to be joined. The helical-faced element is fixed to a circular pin with threaded ends which are seated in polyamide nuts fixed to the rail ends. When the gap between the rail ends changes for any reason, the axial movement of the rail ends causes the bridging section to perform a slight rotating movement and due to the particular shape of the helical surfaces, the surface of the rail over which the collector travels has no gap.

Title: Fire protection door with actuating mechanism - has coupling pin between emergency and normal actuator decoupled in emergency
Inventor: BRINK KARL
IPC: A62C2/18
Filed: 1974-03-25
Abstract: The fire protection door has an automatic closing mechanism and a mechanism for opening and closing purposes. The automatic closing mechanism for opening and closing purposes. The automatic closing mechanism and the normal closing and opening actuation mechanism are disconnected automatically in an emergency.

Filed: 1974-10-15
Abstract: A punctiform light source is used, and a mirror oscillating about an axis parallel to the film direction of movement, at a frequency higher than the highest frequency to be recorded. Sound is reproduced by a narrow light beam passing through the exposed and developed film, with the transmitted light converted into electric signals, amplified and converted into audible signals. Sound signal, is during recording compared at certain time intervals with a number of analogue quantities. A digital signal is generated in accordance with the comparison result, and used for the light beam modulation. The mirror oscillates with a constant amplitude at a higher frequency than the digital signal pulse rate. During scanning the digital signal from the photo-electric transducer is amplified and converted into an analogue sound signal.

Title: Acoustic indicator for direction flasher - with programmed sequence to warn driver of self cancelling not operating
IPC: B60Q11/00
Filed: 1975-02-15
Abstract: The direction flasher circuit is fitted with a timing control circuit linked to an acoustic warning signal. The warning circuit is initiated after different time intervals, depending on driving conditions, if the flashers have not been cancelled. The different programmes take into account vehicle speed, if the vehicle is stationary or moving, vehicle acceleration and retardation, and alternate control operation as in overtaking. In all these cases the acoustic warning is operated with increasing loudness until the driver cancels the controls. The system reinforces the mechanical self cancelling system.

Title: Concentrating highly viscous spent alkaline cellulose lye - by direct heat exchange with gases contg. steam or water
Inventor: HEINZ ERNST DIPL ING
IPC: D21C11/10
Filed: 1975-02-19
Abstract: Concentrating highly viscous spent cellulose lyes, such as the lye from the alkaline boiling of bagasse, by a direct heat exchange at an elevated temp., is improved by using as a heat-carrier a gas whose water vapour concn. reaches 50% after the heat exchange. The temp. of the gas, before it enters the heat-exchanger, is pref. at least 350 degrees C (esp. >400 degrees C). The heat-carrier gas is pref. a part of the combustion gas stream from the boiler (or a separate low-pressure burner) with addition of steam and/or water. The steam can be produced by heat exchange with effluents; it can be used as a sole heat carrier. The gaseous effluents from the heat-exchangers are pref. directed to the boiler (or otherwise recycled), where the malodorous substances are oxidised. The final concentration is carried out using a heat carrier having a high water content and, hence, a high heat capacity. The contamination of the atmos. is avoided by oxidising the malodorous substances in the boiler. The process is simple, and good economy is achieved.

Title: Toothed timing belt for compression ignition engines - has belt inner teeth driving cam shaft and belt outer surface driving rollers
Inventor: HOFBAUER PETER DIPL ING
IPC: F16H7/12
Filed: 1975-06-04
Abstract: The cam shaft (2) and the fuel injector pump (3) are rotated by a timing belt provided with a toothed side (6) and a plain side.

Title: Gas-operated cigarette lighter - uses additional side gas outlllet and mushroom-shaped top outlet for reliable ignition
Inventor: RABE PETER
IPC: F23Q2/16
Filed: 1975-08-28
Abstract: The gas operated lighter, ignited by an electrical spark has a a housing, a fuel storage, and a burner mechanism. The lighter produces a slim flame requiring a narrow gas supply channel (9). The design provides a low velocity space around the outlet jet (10) by providing an additional escape for the gas in the form of side outlet (11) created by a notch in the wall (4) of the gas supply tube (13). The top of the supply tube (12) is enlarged in a mushroom shape (14) there forcing the gas coming out from the side outlet to spread out and produce a low velocity gas/air mixture which ignites easily.

Title: Precision casting process in which the runner bar is kept molten - by making it the sec. winding of a transformer
IPC: B22D25/02
Filed: 1975-11-04
Abstract: Precision casting process uses a runner system leading to mould cavities. The novelty is the use of a transformer yoke with a prim. winding on one end connected to a power supply, the yoke being arranged so that the runner system forms the sec. winding in which current is induced in order to retard the solidification of the molten metal in the runner system. The transformer yoke pref. possesses a hinge so it can be located round the runner system in which heat is generated to control the cooling rate of the melt, esp. where the runner system and patters are surrounded by a ceramic shell, for casting clusters of objects. Used, e.g. when using a lost pattern made of wax or plastic. After the castings have solidified, the molten metal in the runner system can be poured back into a furnace or other vessel. There is thus a substantial energy saving as there is no need to cut off and remelt solidified runners and risers normally present on a cluster of lost wax castings.
