Title: Filter for diesel fuel with integral heat exchanger - in cover and very close to fuel inlet passages
Inventor: STRAUBEL MAX DIPL ING DR
IPC: F02M37/22
Filed: 1978-10-19
Abstract: The heat exchanger of a filter esp. for diesel fuel having a filter cover provided with an inlet and an outlet, has its own inlet and outlet. These are connected by bored channels which together with the inlet and outlet lie at right angles to the long axis of the filter. The channel joining the two channels from the heat exchanger inlet and outlet is bored through a tubular section and runs close to the internal opening of the filter inlet. Used to integrate the heat exchanger into the cover so that the cover is compact and can be combined with existing filter boxes. The cover is easy and cheap to mfr. and requires no more room then an existing filter cover without the heat exchanger. The filter box can be changed without the need to interfere with the cooling water circuit.

Title: Positive displacement hydraulic pump or motor - has throttled leakage flow from discharge to suction to position rotor axially
Inventor: MOENCH GERHARD
IPC: F04C15/00
Filed: 1978-10-27
Abstract: The machine has a rotor (2) within a casing with two end plates containing the shaft bearings. There are axial clearance gaps between the end faces of the rotor and the stator end plates. A recess (8) in each stator end plate faces the rotor end face and is connected by a passage with the machine high pressure side (5). The passage contains a throttling orifice (9) and fluid leaks through the orifice and the clearance gap from the high to the low pressure side. The axial force on the rotor depends on the pressure distribution in this path which in turn depends on the width of the clearance gap.

Title: Coin return dispenser for vending machine - has cylindrical security flap operated by user
Inventor: KOELBL RICHARD
IPC: G07F9/04
Filed: 1979-05-08
Abstract: The cylindrical flap completely blocks access to the coin shoot when operated. The horizontal, hollow cylindrical dispenser is partly cut away, the open portion facing into the machine towards the coin shoot in the normal rest position. The ribbed, closed part of the cylinder protrudes forward through a window and is therefore accessible to the user. When a button has been pressed the returned coin drops into the cylinder which is now rotated manually against a spring by the user so that its open portion faces the window. As the cylinder is completely round, without any protruding lips etc., its angle of rotation is not limited, thus facilitating design and mfr.

Title: Electric power generation method - using water flow, wind, friction and water pressure conditions together with earth's magnetic force
Inventor: GROBE WERNER ING GRAD
IPC: F03D9/00
Filed: 1979-07-17
Abstract: The electric energy generation method involves water and wind power, assisted by pumps, to drive the generating turbines.

The system can combine all known facilities, such as storage batteries, friction, wind power, vacuum, water pressure and suction, cooling to +4 deg. K, as well as the earth magnetic force. It can be also assisted by solar energy, sea wave power and natural (wind) or artificial air streams. The generative system has the advantage that it can be used under all weather conditions, on land and sea, and may be developed into a mobile system, with particular use on beaches and off-shore platforms.

Title: Supercharger for vehicle IC engine - uses exhaust gases to drive bladed double rotor to compress air variably
Inventor: KICKBUSCH ERNST DIPL ING
IPC: F02B37/00
Filed: 1979-08-24
Abstract: The supercharger for an internal combustion engine uses a combined rotary and oscillating action. The exhaust gases drive a double rotor while expanding which compresses the fresh air sucked in. The rotor has radial blades which form cells which change their volume in a sequence which allows the combustion gases to expand. This change in volume is controlled by two concentric shafts which are connected with elliptical gearwheels or a crank drive which give the periodic change in volume. Where elliptical gearwheels are used double gearwheels are mounted on spindles rotating around central gearwheels and supported inside an oscillating cage. They drive one set of blades to expand the exhaust gases with another set of blades alongside on the same drive shaft to compress the fresh air.

Title: Rocket guide vane mechanism - has axially-sliding synchronising ring which can not turn when coupled to vane bearings
Inventor: DIESINGER WALTER PROF DIPL ING
IPC: F42B10/16
Filed: 1979-12-07
Abstract: The missile guide vane mechanism is partic. for rockets, having spindles fixed to the missile and parallel to its axis, and on which vanes with guide surfaces pivot between the folded and extended positions under the action of a power mechanism. The missile (1) has a synchronising ring (8) sliding axially but which cannot turn, positively coupled to the bearing of each vane, so as to allow relative movement between them. For each bearing (6) there is a guide extending in the sliding direction and inclined to the missile axis, forming a ramp face determining the relationship between the torque necessary for unfolding the vanes and the thrust to slide the ring. Thus sliding movement of the ring and unfolding movement of the vanes are synchronised.

Title: Telephone subscriber's appts. with internal loudspeaker - having acoustic enclosure and horn to improve reproduction quality
Inventor: KRAPP KARL HERMANN ING GRAD
IPC: H04M1/62
Filed: 1980-10-21
Abstract: The proposed construction improves the quality of speech reproduction by largely eliminating the undesirable feedback and resonances usually present. The loudspeaker is contained in an enclosure whose shape is designed to minimise reverberances which, when they act on the reverse side of the loudspeaker cone, distort the reproduction. The loudspeaker is attached by an elongated cone or horn directly to the outlet port in the enclosure. This port typically faces the loudspeaker grille in the telephone subscribers appts. case. In a practical design the enclosure base is fitted with feet or lugs by which it is secured on the bottom of the case.
