Title: Sausage loop presentation device - with feeding flight, cutter blade and flexible pusher
Inventor: MUENZ HANS
IPC: A22C11/12
Filed: 1978-01-27
Abstract: A device to present suspension loops to a sausage filling machine contains a reel with a wound strand of loops which is unwound and pulled along a groove by a flight. Locating plungers hold the strand as a cutter balde cuts off a certain length and a flexible pusher moves the loop along a guide tube to the sausage filling machine. This requires no manual intervention and automatically presents the suspension loops to the sausage filling machine.

Title: Photocopier drum with removable layer - has reversing switches on inside of hinged access plate
Inventor: SCHALLER NORBERT
IPC: G03G15/00
Filed: 1978-03-30
Abstract: The drum of the photocopier is clad with the photosensitive layer, clamped into a slot in the drum and with the trailing end overlapping the slot.

Title: Vehicle automatic gearbox moment measurement on fixed parts - is by determining stress in or deformation of supporting couplings linking fixed gear stage to housing
Inventor: MUELLER ALFRED DR ING
IPC: G01L3/02
Filed: 1978-11-09
Abstract: The method is for measuring the torque of a drive system, esp. the automatic gearbox of a vehicle combustion engine, and involves making measurements only on non-rotating parts and gives results independent of temp. and geographical altitute. The movement generated in an element supporting the gearbox on its mounting is measured and multipled by a proportionality factor related to the known transfer ratio of the gearbox or stage. This enables indication of the transmission ratio. The moment in a coupling linking a fixed gear state to the housing is measured and compared with a defined threshold level to produce a switching signal. The moment may be determined by measuring the mechanical stress in a deformation of the gearbox housing or an attachment.

Title: Tolerance curve display for video screen - uses two memories to store curve and tolerance data on basis of lines and positions
Inventor: HORNUNG MANFRED ING GRAD
IPC: G01R13/30
Filed: 1979-04-06
Abstract: A television style raster display is used to display tolerance curves. Data is stored in two memories (BWS1, (BWS2), one of which remembers the horizontal position and the other the particular raster line. The two stores are driven by address signals at the video rate and produce an output which controls the brightness of the video beam. The scheme provides an economical store of the data and the raster display is convenient for illustrating the tolerance boundaries as well as the actual curve. The output of the first memory (BWS1) passes through a comparator (V) to logic elements, and the output of the second direct to logic elements, which consists mainly of AND gates.

Title: Control of fruit ripening by atmosphere control - using molecular sieve bed with pressure swings to adjust oxygen content of storage container
Inventor: KURZ RENE
IPC: A23L3/3418
Filed: 1979-05-31
Abstract: The O2 and N2 components in an air mixture are adjusted inside a closed storage space. This done by an adsorption-desorption process with changing gas pressure. An air mixt. from atmosphere or from the storage space is compressed and pumped into an adsorber vessel. At least part of the excess pressure is then released by venting the O2 rich mixt. to atmos. The residual gas is then removed by partial evacuation and pumping to a second adsorber. The process is continued until the required level of O2 to N2 is achieved. This mixt. is then pumped into the storage space. Used to reduce the O2 content in stores, silos, containers, ship holds, etc. When fruit, grain or other foodstuffs are being stored. Allows for prolonged keeping of fruit, vegetables, wheat, seeds, nuts, plant parts, flowers, meat, fat and eggs, without the use of fuels to generate low O2 gas. This is done in short time and allows the produce to be safely transported by sea, rail or road.

Title: Adaptor for IC engine - has all components in compact unit and uses engine cooling passages as boiler
Inventor: HINTZE RUDOLF
IPC: F02G5/04
Filed: 1979-08-29
Abstract: The radiator of a conventional engine is replaced by an air cooled condenser (7) for refrigerant. A pump (6) draws refrigerant from the condenser and delivers it to an injection pump (5). The injection pump forces the liquid into the cooling passages of the engine (1). It flows through these and evaporates while cooling the engine. The resulting vapour flows (9) into a vapour engine (4). The exhaust (10) of the vapour engine returns to the condenser (7). The vapour engine (7) is coupled to the internal combustion engine by a belt drive (3) which replaces the radiator cooling fan drive. The entire adaptation is easily made to any existing engine.

IPC: B22D11/00
Filed: 1979-12-28
Abstract: Molten alloy flows downwards through a nozzle located in the bottom of a vessel so it is quenched on a moving chill or casting wheel; and the chill or casting wheel is kept at a constant distance from the bottom end of the nozzle. The constant distance is pref. obtd. by using an air cushion or a film of lubricant between two sliding surfaces, or by rollers running on the casting wheel. One pref. appts. uses a carrier frame in which a crucible contg. the molten alloy is located, a nozzle being fitted in the base of the crucible. The frame is fitted with rollers running on the periphery of the rotating casting wheel so the frame moves vertically to keep a constant distance between the wheel and the nozzle. Used for, e.g. casting (I) Ni40Fe40P14B6; or (II) Ni45Co20Cr10Fe5Mo4B16. Casting wheels 0.2-2 metres dia. can be out of round, so cast strip of varying thickness is obtd.; the invention minimises such variations.
