Patent DE-2106344-A1 (DE)
Title: Vegetable protein - esp soya protein, free from unpleasant taste, as food product
IPC: A23L5/20
Filed: 1971-02-10
Abstract: A food prod. which is free from taste is prepd. from a de-fatted vegetable protein which forms an aq. suspension with pH =8, by rapidly and dynamically heating the suspension to 105-205 degrees C. and subjecting it to direct mechanical action, keeping the suspension for a short time under an excess press. sufficient to prevent evapn. of water from the hot suspension, suddenly releasing the press. on the heated suspension so that substances of unwanted taste and smell are removed with the evaporated water, and sepg. the vapours from the suspension, to give a taste-free vegetable protein prod. The process is esp. used for soya protein. The bitter flavour is removed from vegetable proteins, giving a taste-free, palatable, edible prod. which has good dispersibility and can be used in place of prods. such as milk.
Patent DE-2106406-A1 (DE)
Title: Characteristic frequency measuring circuit - is for four-pole networks and uses only one regulated precision generator
IPC: G01R27/28
Filed: 1971-02-11
Abstract: The circuit measures the characteristic frequencies of a four-pole network (2) using one regulated precision generator (6). During the regulation period a frequency controlled voltage generated by the frequency or phase comparator (11) and the control voltage store (12) sets the frequency controlled oscillator (10) to a frequency determined by the precision generator (6) and the program generator (8). The program generator (8) sets the precision generator (6) frequency and switches it (9) to the comparator input (11). In the subsequent measurement period the precision generator (6) is switched to a second frequency and outputs directly to the measurement transmitter (1) or receiver (3).
Patent DE-2134182-A1 (DE)
Title: Drive unit for spaceship - uses acceleration and gravitational forces aided by electro-magnetic forces to produce gaviton
Inventor: HANSCHMANN HORST
IPC: F03H99/00
Filed: 1971-07-09
Abstract: During free fall, acceleration produces a track plane displacement in the atoms of the accelerated mass of the circling pairs of electrons and of the corresponding particles in the graviton. This operates using the acceleration of corresponding rotation systems in crystals or of the electrons in metal or magnetisable atoms in chemical combination with other particles. The apparatus makes use of magnetic fields which may alternate at high frequency or be of steady strength. Vortex flows are aided by an electric motor through the induced change of speed of rotation in both rotation tracks of the paths of the electrons and by pressure from sound and ultra sound waves analogous to the strike of a hammer on to a magnetic rod, thus producing negative gravitation waves or gravitons which serve to accelerate a drive system in an already present gravitational field.

Title: Electroacoustic amplifier for music and speech reproduction - uses division of entire range of AF channel into woofer and tweeter regions
IPC: H03F3/183
Filed: 1973-08-13
Abstract: The amplifier is especially for radio and television application and it can also be used with record players and tape recorders. The whole audio frequency range of a channel is split in two different power ranges, i.e. the lower and higher frequency ranges (woofers and tweeters), whose secondary outputs are connected in opposition and only acoustically coupled. The nominal power ratio between the lower and higher frequency ranges is 1:4, which was found to produce pleasant sound reproduction. The acoustic compensation removes the mechanical accents from musical instruments oscillations, with simultaneous reduction of harmonics.

Title: Production of smoke for fish curing - using cylinder with bed of wood chips etc. with combustion air entering base
IPC: A23B4/052
Filed: 1974-03-12
Abstract: Smoke suitable for curing fish or fish prods. is produced in a cylinder, in the lower section of which is a bed of suitable fuel, e.g. wod chips. Combustion air under pressure enters the base of the bed and the fuel burns at the base of the bed. Smoke so produced passed up through the bed where it is cooled, filtered and aromatised, before leaving the cylinder, suitable for use in curring plant. The fuel can consist of wood, wood chips, sawdust etc. The height of the bed is controlled by a float which adjusts the input of fuel by screw, belt etc. The builk density of the bed is kept constant by rotating a stirrer with arms projecting into the bed. This also ensures uniform movement of fuel down the bed, and uniform voidage thus providing uniform contact with the smoke. It also prevents the hot zone from rising above the required level.

The feed system has a workpiece dia. sensor whose output is varied in relation to the wheel dia. by the command signal, provided by the feed rate adjust. The control system operation is based on the radial speed of the cutter slide and the longitudinal speed of the longitudinal slide. The combined speed forms the variable which is compared with the command variable corresponding to absolute feed rates.

Title: Emergency stop for heavy roller shutter doors - has catch lever with unequal arms for stopping free fall
Inventor: INGEBRANDT DIETER
IPC: E05D13/00
Filed: 1974-05-28
Abstract: The catching arrangement engages directly with the profiled members of the roller shutter type gate which ensures a high degree of safety. The locking catch (6) is pivoted about an axis (5) which is parallel to the profiled member (21) of the roller shutter type gate. This locking latch is a double arm lever of which one arm (6a) is heavier than the other arm (6b). When the door is lowered slowly the catch lightly touches the profiled members of the gate and hence the upper, lighter arm does not contact the profiled members. When the door falls at a fast rate then the lever arm is thrown downwards by the profiled members and the upper lever arm engages with the profile and stops the fall.
Patent DE-2428109-A1 (DE)
Title: Miniature relay for printed cct. boards - has hinged flap armature and S-shaped magnetic yoke as support member
Inventor: BUEHL HARRO
IPC: H01H50/36
Filed: 1974-06-11
Abstract: The miniature relay is intended for printed circuit boards and has a flap armature serving as the moving contact. The armature is hinged on a magnetic yoke carrying and at least partly surrounding the excitation coil. The magnetic yoke (11) is S-shaped, one its outer shank (12) surrounding the excitation coil (10, 20). This shank carries at its free end the flap armature (13), while the middle part of the shank (14) and the other outer shank (17) are inserted into the excitation coil and form the magnetic pole (15) for the flap armature. These parts are preferably held in the coil-former (10) reception space by wedge-shaped clamping extensions (19). The magnetic yoke may be secured in a circuit board by the shouldered end of the free outer shank.

Title: Heat-conductive hood intensifying cooking heat - fits over pan and onto gas ring etc. preventing lateral escape of heat
Inventor: SCHULT OTTO F W
IPC: A47J36/36
Filed: 1974-07-10
Abstract: The heat conductive hood which is designed to prevent the loss of heat around the sides of a pan on a gas or electric ring comprises a sheet steel frusto-conical hood which has a large outer edge which rests on the cooking ring and a smaller inner edge which covers the lid of the pan. The vertical height of the hood depends on the size of the pan so thant when the pan is placed on the cooking ring any heat which could escape to the atmosphere is drawn up inside the hood and passed to the food. Furthermore, the heat is no longer concentrated only on the base on the pan but is distributed over the larger surface are formed by the sides of the pan.

Title: Typewriter cleaner with wick and breakable ampoule of cleaning fluid - has thermoplastics wick holder for easy leakproof connection with sleeve
Inventor: KNAPP FRANZ
IPC: A47L25/08
Filed: 1974-08-12
Abstract: The cleaning apparatus has a thermoplastics compressible sleeve closed on one side and enclosing a breakable ampoule of cleaning fluid and a wick or fibrous wad for applying the fluid which is inserted in the open end of the sleeve where it is firmly enclosed by a thermoplastics wick holder. This holder may be formed by a tube or tubular foil extruded over the length of the wick or by a helical strip of foil shrunk onto the wick but since the holder firmly surrounds the wick the diameter of the loose wick is reduced to about half the diameter of the sleeve so that it can be readily inserted without special skill.
