Title: Thermally powered heat pump system - has drive medium flow with sequence of heat exchangers for full exploitation
Inventor: HERRMANN HANS DIPL ING DR
IPC: F25B30/00
Filed: 1975-06-27
Abstract: A heat pump which is powered by thermal energy is constructed in such a way that the drive medium flows through one or more sequentially connected and arranged heat exchange devices after it leaves the drive section of the pump itself. The system is so arranged that part of the heat is transferred to the medium in the heat exchanger which is to be heated, i.e. to the hot circulation medium or to the cold circulation medium, and partly to the heat-evolving cold medium. The primary energy is thereby fully exploited with a lowering of pollution. An absorber heat pump can theoretically use working heat not only to the temp. of the medium to be heated but also to the surrounding temp. of air, water or earth.

Title: Pneumatic conveyor system feeding machines with loose material - has side conveyors of doubled cross section leading from central conveyors to receivers
Inventor: OHLMANN HANS-ARMIN DIPL ING
IPC: B65G53/24
Filed: 1975-07-11
Abstract: The pneumatic conveyor system feeds machines with loose material, e.g. plastics processors having injectors, extruders, blowers etc. requiring automatic feeding of powdery or granular raw material. Side conveyors are provided leading from the central conveyors to the receivers. The side conveyors have approx, twice the pipe cross-section as the central conveyors. An opposing stream is generated in a central conveyor air lead in a section not loaded with conveyed material. This steam is effective from the suction opening to the operated side conveyor(s) leading to any receiver which has been signalled as empty. This opposing stream overcomes excess travel of the material due to inertia.

Title: Clutch servo control for automatic transmission - with damper in throttle linkage to smooth full throttle or sudden gear change
Inventor: BREISCH HARALD DIPL ING
IPC: F16H61/04
Filed: 1975-09-04
Abstract: The automatic transmission has a servo operated clutch in which the servo pressure is set w.r.t. the torque demands on the engine. A series of set pressure control apertures are used for this. In order to ensure an even gear change if the throttle is suddenly pressed during gear change, or is held down during gear change, a damping circuit is included in the throttle linkage. This can take the form of a flow restriction and a balancing reservoir. For electronic control an electric damping circuit is used. A non-return valve, or a diode, is connected across the damping circuit so that if the throttle is released during gear change, for braking etc., then the torque can be rapidly reduced.

Title: Erection of multi stores undergrown structures - features sinking of bore pile foundations with spaced supports for various floors
Inventor: WALTHER RENE
IPC: E02D27/10
Filed: 1975-09-10
Abstract: Erection of a multi-storey underground construction where bore pile foundations are set up in the ground where the structure is to be erected and there are a number of supports which carry the structure floors on the pile foundations. The bottom floor/cover is then concreted in the earth plane, leaving openings which pass through the floor for the free passage of the supports. A second and further floor are then concreted and the surface of the bottom floor serves as shell base while all floors, together form a floor stack. This floor stack is then suspended on the head part of the supports and the ground below the bottom floor of the stack is excavated in one or more stages. The bottom deck is then lowered to a given height along the supports and the floors are set on the aforementioned devices which support the floors on the supports.

Title: Self loading tipping skip lorry - has ram driven coupling claw on tipping surface to hook onto bottom front of skip
Inventor: KALLABIS GUENTER
IPC: B60P1/64
Filed: 1975-10-14
Abstract: The self loading skip lorry has a support frame hinged about the rear end of the lorry and fitted with guide rails to slide the skip. Long stroke rams in the frame drive a coupling claw which hooks onto a coupling handle at the bottom front of the skip. The skip is raised from the ground by inclining the frame and moving the hook to the end. The whole operation can be controlled from the cab, with the coupling operation also remote controlled. The frame is hinged on short support arms pivotted at both ends, so that a shallow slope can be achieved. This allows the skip to be transferred in conditions of low headroom. The inclined frame can transfer the skip between different heights.

Title: Monitor for fuel consumption - expresses fuel flow rate and air intake as voltages which bear fixed relation during efficient consumption
Inventor: KURZ RUDOLF ING GRAD
IPC: G01F9/00
Filed: 1975-11-13
Abstract: The fuel consumption monitor checks the amount of air consumed for combustion of a given amount of fuel. Two voltages are derived, are from a meter measuring the fuel flow rate. The other is derived from the air intake rate. A capillary pulse (1.2) in front of the carburettor is used to produce from the air stream a mechanical movement (1, 4). This movement adjusts a potentiometer (1, 5) acting as a voltage divider. The voltages are compared in a comparator circuit. If they are unequal or voltage appears at the output and indicates via lamp the faulty operation.

Title: Putty type repair compsn. for hard rubber coatings - from hard rubber elastomers and a liquid butadiene polymer
Inventor: PETZOLD HEINZ
IPC: C08L21/00
Filed: 1975-11-22
Abstract: Putty type compsn. is for repair of hard rubber coatings. The required putty consistency is obtd. by adding normal hard rubber mixts. of elastomers to proportions of a liq. butadiene polymer which together with the elastomers forms a hard rubber. The patent compsns. used to repair hard rubber coatings, are equal to normal hard rubber prods. w.r.t. the swelling behaviour, stability characteristics, hardness, adhesion to metals, strength etc. Their prepn. allows the use of fast accelerators in amts. which do not affect the stability behaviour. Consistency can be easily regulated by the formulation. The high flexibility of the putt-like compsn. is a pre-requisite for the filling of edges and grooves in containers. In an example hard rubber paste consisting of a butadiene elastomer and a liq. butadiene polymer (70:30), contains fillers, a quick accelerator, the theoretical amt. of S and cross-link activators. The mixt. is rolled to a thickness of 3mm and then wound into a roll with the layers sepd. by a profiled PE foil. The material can be used to repair e.g. cracks in hard rubber coatings by application and vulcanisation at 90-100 degrees C for 6-12 hours.

Title: Multilayered chimney sealing and heat insulation - has air space filled with injected fireproof material
Inventor: STEINGAERTNER GERHARD
IPC: E04G23/02
Filed: 1976-03-03
Abstract: The sealing and insulation is applied where injection is carried out on multi-layered and/or multi-flued chimneys, with a layer of air as insulation between the inner and outer membrane, usually resulting in some areas being ineffectively sealed, causing health dangers. The object is to effect perfect sealing while retaining the full cross-section, and without impeding operational reliability. The layer of air is replaced by an insulating layer, the space being filled with fireproof material which effects a subsequent sealing of the chimney. The injection process can also serve to promote heat insulation.
