Title: Vehicle horizontal lifting platform - has arms clamped in position by rods passing through guides and pivoting near them (NL090976)
Inventor: TOL DIRK
IPC: B66F7/02
Filed: 1975-12-17
Abstract: The platform is partic. for motor vehicles, having one or more columns each with a supporting frame equipped with arms which can be swung down against a horizontal supporting surface. Each arm has a shoe, so that the vehicle can be lifted at points other than the wheels. The arms are clamped (9, 16) in position in relation to the frames (6, 7) by guide rods (21, 24) mounted near their pivot points, passing through guides (25, 22) fixed to the arms , and clamped into engagement with them. Each guide can be in form of two levers alongside each other, pivoting on the arm, and with openings in them leaving plenty of clearance as the rod passes through. Two clamping rings fit closely round the rod between the levers, thrust apart by a spring so as to bear against them and cause them to grip the rod.

Title: Hot-filled material container - has membrane compensating for internal pressure alterations while cooling down
IPC: B65D77/20
Filed: 1976-03-08
Abstract: Container is for liquid or pasty material, with which it is filled when hot, having a flanged edge parallel to the bottom and to which a cover is sealed. The bottom is made larger than normal to allow it to be thrust outwards when filling, and then inwards for the same amount to expel air and allow sealing of the cover. The cover (2) seals the container (1) so as to make it impermeable to liquid. The container has a portion (10) acting as a membrane to compensate for pressure alterations inside as the contents cool down. The cover itself can be in the form of a membrane, having a groove formed in it running parallel to its edge.

Title: Construction of subterranean section of power station - for waste heat utilisation, using known and new building elements
Inventor: SCHLEICH JOSEF DIPL ING
IPC: F25B30/00
Filed: 1976-03-18
Abstract: A pressure cylinder is set up in a terrain comprising loose material by means of a circular injection down to the lowest level. The bottom partition is produced in the shape of a dish by partial injection, before the actual excavation. The central section below ground is surrounded by an apron forming a water storage reservoir which is covered over with the excavated spoil. This apron holds back the outside cold ground water table and encloses heated cooling water, the heat of which is used in heat pumps or turbines or is distributed through a communal hot water network. Prefabricated building units of PVC are used as load bearing partitions and covers, etc. The thermal efficiency of a power station is increased and damage to the environment by waste heat is avoided.

Title: Static electricity (dis)charge device for insulating surfaces - uses suspended cable with dependent electrodes that are brought into close proximity to surface for (dis)charging
Inventor: SCHULZE HARALD
IPC: H05F3/04
Filed: 1976-04-01
Abstract: The charging or discharging of static electricity on an insulated material, e.g. paper strip or plastic foil is effected by suspended cable with dependent electrodes.

Title: Seed drill row marker - has marking element formed by wheel to identify travel lanes
Inventor: DREYER HEINZ DIPL ING DR
IPC: A01C7/08
Filed: 1976-12-11
Abstract: The operating width of the machine is greater than the track width of the towing tractor and the machine has a supply tank with seed outlets. To create travel lanes for the tractor wheels, strips of the seed are kept free in a periodic return, which is determined by the ratio of the working width of the machines following in particular operations to the working width of the seeding machine.

Title: Biological water filtration - alternating water and air filling for filter by siphon and pump action
Inventor: SCHUSTER HEINZ DIPL ING
IPC: A01K63/04
Filed: 1977-01-03
Abstract: A biological filtering process of fluids, e.g. of water, fills the filter with water and with air in turn. The cycle is pref. automatically maintained by combining a siphon with a delivery pump of less capacity than the siphon. A pump passes the fluid from the consumer basin to the filter inlet where it is distributed by the grid over the filter packing. The siphon is so designed that it extracts the filtered water at a faster rate than the pump can deliver. The continual supply of air provides the oxygen for the active mat of biogenic bacteria on the filter. The filter efficiency in increased and a min. of moving parts is required for the automatic operation of the system.

Title: Overheating protection for photocopier - has spring-loaded heat shield released by solenoid upon malfunction
Inventor: ISHIKAWA KEIICHI
IPC: G03G15/20
Filed: 1977-01-18
Abstract: The thermal fixing station (1) of the photocopier is fitted with a sliding heat shield plate (5) which is pulled aside during normal operation and which is slid between the copy and the heaters during a malfunction of the machine. The plate is moved to the shielding position by a spring (9) when released by a solenoid. A main solenoid (18) pulls the shield aside at the start of the copy process, with the edge of the shield retained by a sprung claw. The solenoid current is switched off and the plate remains tied to the claw. To release the plate a small solenoid, linked to the malfunction control releases the catch and the spring pulls the plate into the protective position. The system uses no power during the standby mode.

Title: Household hot water heat recovery system - passes used hot water through heat exchanger tank to partly heat fresh water
Inventor: BIESTERFELDT HARALD
IPC: F24D17/00
Filed: 1977-02-21
Abstract: The heat recovery system for hours hold use, consists of discharging all hot waste water through e.g. a coil inside a fresh water tank before it is finally discharged into the drains. The tank and coil thus form a heat exchanger. A valve and thermostat system can be used to divert cold water directly to the drains. The heat exchanger tank can be installed in a cellar. The water from a washing machine is especially useful, and new equipment can accordingly be designed for inclusion in the water heating system. The partly heated water can then be heated to a required temperature by a conventional boiler.

Title: AC mains isolation resistance monitoring circuit - measures DC voltage developed by constant current generator
Inventor: KREUTZ WALTER DIPL ING
IPC: G01R19/10
Filed: 1977-02-25
Abstract: A circuit arrangement for monitoring the isolation of an alternating current mains network involves superimposing an auxiliary electrical parameter on the network. Two constant current generators (Q1, Q2) supply equal currents (Ic1, Ic2). The current fed from the first source (Q1) flows through a choke (Dr) and the AC mains network with its isolating resistance (Riso) and results in a voltage appearing at the non-inverting input of a differential amplifier (V1). The current from the second source (Q2) flows through a compensating choke (Lk) to earth. The DC voltage drop across the compensating choke is fed to the inverting input of the differential amplifier. The output voltage of the differential amplifier (Um) depends linearly on the isolation resistance of the network. The choke and compensating coil are thermally coupled so that the circuit is not temp. sensitive.
