Title: Sealed filter packing for single cup of coffee - has gas-tight powder chamber torn open immediately before use
Inventor: BEDNARTZ HUGO
IPC: B65D81/00
Filed: 1973-05-29
Abstract: The packing is for the preparation of a cup of coffee using a metered amount of powder sealed into a filter bag. In the filler area of the bag a sealed coffee powder chamber is provided, for opening immediately before use. The chamber can be in the form of a round-based trough or a hollow cylinder, or a flat bag, and provided with a suspension thread, also weakened lines for tearing open. The tear-open section can have on its underside a punch for piercing the base of the bag, which can be of Al foil. This allows the coffee powder to enter the lower filter bag portion of the assembly.

Title: A.C. motor supply cct. from D.C. voltage source - has motor three phase coils connected in collector-emitter ccts. of three transistors as operating resistors
Inventor: SPINNER GEORG DIPL ING DR ING
IPC: H02P23/28
Filed: 1973-06-19
Abstract: The circuit uses an inverter with the motor three phase coils each as a resistive load in a drive transistor collector-emitter circuit. The three transistors have cyclic feedback, e.e. the base of one is coupled to the collector of the previous one etc. The transistors emitters are coupled to a common D.C. pole. R.C. timing elements are included in the feedback loops to ensure that the transistors operate cyclically. The R.C. elements may be used for frequency or speed adjustment. The drive motor characteristic may be effected by incorporation of reactive resistors.

Title: Cine projector film feed - uses step motor controlled by shutter synchronised signals
Inventor: WAGENSONNER EDUARD
IPC: G03B1/18
Filed: 1973-06-28
Abstract: The projector uses a rotary blade shutter whose spindle carries one or more cam projections. These close a pair of switch contacts whenever the shutter obscures the projection window. The switch signals are fed to a motor control unit containing a trigger circuit which energises a set of windings in sequence to act on matching permanent magnets of the motor. The motor spindle is fitted with a sprocket which engages the film perforations. The control system and the sprocket diameter are matched to move the film by one frame per step. The design replaces the mechanical claw with an electrical system less subject to wear.

Title: Flow volume measuring and recording device - measures optically transparent liquids whose flow velocity is low
Inventor: EHRHARDT MANFRED DIPL CHEM DR
IPC: G01F1/10
Filed: 1973-11-09
Abstract: The pickup delivers no mechanical power, apart from overcoming a small bearing friction. The pickup consists of a rotor with four optically polished plane vanes at a right angle to each other. A light ray is reflected by one of the vanes, and by a vane at a right angle to it, and falls on a photoresistor or a similar device. Light flashes produced by rotating vanes are converted into electric pulses used for measurement and/or recording of the liquid volume flowing through the test cell. The device is very sensitive since it does not depend upon force of flow against mechanical parts.

Title: Corrugated paper separation from other domestic refuse - using mechanical sifting combined with hand picking
Inventor: BUCHBINDER ROBERT I
IPC: B07B1/10
Filed: 1974-06-18
Abstract: The process assemunes that most of the corrugated paper will be present in sizeable pieces, physically larger than most of the other items. The refuse is unloaded on to a conveyor composed of separate strands spaced six inches apart. The smaller items, tin cans, etc. fall through the gaps and are removed. At one point during its travel the refuse is tumbled through a free fall of three feet. Pickers, standing on platforms alongside the conveyor, remove by hand any unsifted items not made of corrugated paper as well as any soiled pieces. The salvaged clean paper goes for shredding and bundling ready to be sent away to the paper mill for re-processing.

Title: Anti-theft protection for car - with battery and isolating switch in armoured container in engine compartment
Inventor: LEPPER WILHELM DR ING
IPC: B60R25/045
Filed: 1974-08-06

Title: Double wedge control for rolling mill stand - giving wider range of roll gap settings
Inventor: POLJAKOW MICHAIL
IPC: B21B31/30
Filed: 1974-10-24
Abstract: Rolling mill stand comprises a framework in which are mounted bearing blocks, with the rolls and mechanisms for the control of the roll spacing each comprising a wedge placed between the frame and the blocks, and a threaded screw nut unit the single start threaded female of which is fixed into a fixed part of the frame and the control screw is joined to the wedge, so that, when the screw turns, the roll joined to the wedge by means of the blocks, moves in the radial direction, controlling the spacing. The mechanism specif. has a supplementary double wedge joined to the slope of the main wedge and a two-start female thread of the same hand and the first, one-start female thread cooperates with a two start screw joined to the supplementary wedge so that rotation of the screw produces a displacement of the principal and supplementary wedges in opposite directions, so that the rolls can be displaced radially further by turning the second screw. The rolling mill stand can be used for a much wider range of thickness settings using the double wedge arrangement.

Title: Heat engine combined with fractionated distillatory - utilises energy of flowing gases to do mechanical work
Inventor: BACHL HERBERT PROF DR ING
IPC: B01D3/30
Filed: 1974-11-05
Abstract: A rotary machine for combined thermodynamic and sepn. effects, e.g. power production and fractionated distillation, comprises a rotor with blades and associated fixed blades. The liqs. fractionated and sepd. by the high flow speed during the change of state (gas to liq.), by the secondary flows occuring at the blades and also possibly by centrifugal action, are concentrated on the outer faces of the moving and/or fixed blades; from here, they pass through openings with guide edges into collecting channels and so to the outside of the machine. The same openings may be used for introducing washing or adsorption liqs. or for recycling to increase concn. The flow direction may be centrifugal (outwards) or centripetal.

Title: Guided missile with projectiles for penetrating heavy armour - carries launching tubes for firing high velocity projectiles for target penetration
Inventor: FUSBAN ULRICH DIPL ING
IPC: F42B12/62
Filed: 1975-01-03
Abstract: The guided missile system for fighting preferably heavily armoured targets combined features of a guided missile and projectile for penetrating heavy armour with high kinetic energy. The guided missile has a number of longitudinal tubes from which are fired, when the missile is close to the targer, a number of projectiles at a velocity which is much higher than that of the missile. These launching tubes within the missile can be arranged at different patterns for achieving the desired dispersion pattern for ensuring hits. For this purpose the launching tubes may be slightly curved or they may be arranged in helical pattern around the missile longitudinal axis.
