Patent DE-2459112-A1 (DE)
Title: Dyeing textile goods in rope form - enables dyeing of longer batches with minimum increase in floor space
Inventor: SCHIRM GUENTER
IPC: D06B3/28
Filed: 1974-12-13
Abstract: An installation for dyeing textile goods in endless rope form consists three communicating dye reservoirs nozzles connecting tubes and guide rollers. The goods are fed to the first nozzle in a specific direction. The flow of the dye liquor under pressure through the nozzle carries the matl. through a guide tube, through a curved section and out into the dye reservoir through the funnel shaped end piece. The material passes through the dye reservoir at a relatively low speed so that it remains in it for about 3 mins. At the end of the first dye reservoir the material passes around a roller and upwards to a nozzle from where it is transported further by the action of the nozzle and arrives in the second dye reservoir where it again dwells for about 3 mins. The goods are then passed again around the roller to a nozzle and thence into the third dye reservoir. From the delivery end of the third dye reservoir the material passes via guide rollers back to the entry of the first nozzle. The guide tubes are inclined downwards in the direction of the material flow and at the inlet end the extension of their longitudinal axis touches the periphery of the guide roller. Substantially longer batches of textile goods in rope from can be dyed without greatly increasing the space occupied by the plant.

Title: Additional drive for motor vehicles - has freely rotating fan in vehicle air stream connected via generator to vehicle battery
Inventor: LEHNHARDT HANS
IPC: B60K16/00
Filed: 1975-01-07
Abstract: The design can be used for vehicles or for cycles, and makes use of the wind driving against the vehicle as it moves. There is a small projection on the front of the vehicle in which a turbine driv or propeller is fitted. This is driven by the wind and is connected to a dynamo (7). The wind pressure is therefore translated into energy input to the battery. Alternatively, the turbine drive (2) can be connected mechanically to the vehicle drive. An air vane or duct (4) can be used in front of the fan to direct the air flow through the fan blades.

Title: Storable mildly-acid meat pickling compsn - contains dried vegetables to absorb some of the juice and add novel flavour notes
Inventor: HENNING WOLFGANG
IPC: A23B4/12
Filed: 1975-02-13
Abstract: A storable pickled meat is made by washing the raw meat, cutting it into pieces, mixing the pieces with pieces of vegetable (e.g. onion) pref. of the same size, seasoning and edible oil, 8-10 wt. % (based on total) of a mixt. of acetic acid, citric acid and salt (and, opt., other edible acids) having a pH of 1-3, pickling the compsn. in (saleable) containers for 18-24 hrs. and finally pasteurising the hermetically-sealed packages for 25-60 mins. (depending on size) at 80-95 degrees C (depending on compsn.). The vegetable additives, which are dried, serve to soak up some of the juice of the marinating meat, introduce a new flavour note and prevent the meat from becoming tough. The contents of the container are fully usable (as opposed to conventional ones where the liq. is usually thrown away). The pickle is not too acid.
Patent DE-2506969-A1 (DE)
Title: Eliminating contamination of atmos. by spent cellulose lye - by oxidising malodorous substances volatilised during concn. of lye
Inventor: HEINZ ERNST GEORG DIPL ING
IPC: D21C11/08
Filed: 1975-02-19
Abstract: Contamination of the atmosphere by malodorous substances volatilised during the concentration of the spent lye from the prodn. of cellulose by alkaline boiling can be diminished by directly contacting the lye with the combustion gases from the boiler and then oxidising the malodorous substances. This method is improved by contacting the lye with a minor part of the combustion gases before the final concentration, and oxidising the malodorous substances with oxygen-contg. gases. The gaseous effluents contg. malodorous substances are pref. directed to the boiler and oxidised there by introduction of O2-contg. gases. This method is reliable and inexpensive.
Patent DE-2509587-A1 (DE)
Title: Coffee grinder with efficient coffee outflow - comprises smooth walled channel with resilient tongue forming build-up chamber with measured release
IPC: A47J42/40
Filed: 1975-03-05
Abstract: The grinder is provided with a smooth walled outlet channel with two parallel sides for conveying the ground coffee from the grinder to a coffee machine for example. To ensure that the coffee is moved along and does not stick to the sides of the channel a resilient tongue is mounted across the parallel walls to form a downwardly tapering build-up chamber beneath the grinder outlet. The tongue is designed so that it only bends back far enough to release a narrow gap through which the coffee can pass under the weight of the build up. The build up of coffee ceases as soon as the mill is switched off.

Title: Cam operated hydraulic piston actuator - uses return valve and pressure storage tank to compensate for leakages
Inventor: SCHEUBE ROLAND
IPC: F15B7/10
Filed: 1975-08-30
Abstract: A cam controlled hydraulic circuit for e.g. a copying machine tool may be used in the sequential control of a set of actuators. Two cam disc operated actuator pistons (2, 3) are connected by pressure conduits (8, 9) to a double acting working cylinder. The leakage losses occuring in the pressure transmitting system between the actuator piston (2, 3) and the working piston of the cylinder are compensated for by a pressure accumulator (19) supplied through two return valves (14, 15). The pressure in the accumulator is the same as, or greater than the pressure required for constant contact of the transmission elements between the pistons (2, 3) and the cam discs (5, 6). With a volume excess in the transmission system, the pressure fluid is returned to the storage tank. The associated valve lifts, when the working cylinder is blocked, and actuates the corresponding limit switch.

Title: Three dimensional flow velocity measurement - by internally heated sphere with thermistor pairs in three coordinate axes
Inventor: NAVRATIL EMIL DR RER NAT
IPC: G01P5/10
Filed: 1976-02-10
Abstract: The three-dimensional flow measurement of fluids such as of sewage in clarification basins uses a heated sphere with with a dia. and surface finish to retain a laminar flow of the boundary layer. Two thermistors in each co-ordinate axis X, Y and Z measure the heat distribution field which has been distorted by the flow. A converter transforms the electrical signals into flow velocity components. A hollow sphere made of gold-plated copper with an inner lining of epoxy resin, contains a heating element with a temp. probe and six embedded thermistors in the three spatial co-ordinate axes. The leads for the heating element and for the thermistors are housed in a hollow stem. This eliminates errors caused by adhesion of fibres and sludge on mechanical moving parts. The response time of the instrument is short and it indicates both rate and direction of any flow.
