Title: Heating system hot water preparation - has boiler water delivered to storage unit for radiators and heat exchanger supply
Inventor: GINGTER THEO
IPC: F24D3/08
Filed: 1974-08-16
Abstract: The process is for the supply of hot water in connection with a heating installation, where the tapped water is heated by means of the heat medium, and at least a partial flow is conducted past a heat exchanger unit delivering the tapped water. The heat medium flow emerging from the boiler is fed into a storage unit supplying the heat medium to the radiators: at least a partial flow is tapped off from the storage unit for heating the exchanger unit. A pump may be used to deliver the partial flow to this unit. The storage unit has supply pipe from the boiler opening into it, and fitted with heat medium ducts for the heating system and for the heat exchanger unit.

Title: Identification of containers - generator causes scanning of ROM coding unit on container to produce modulated output for reading unit
Inventor: SCHIEF ALFRED DR ING
IPC: G06K7/00
Filed: 1974-10-04
Abstract: An identification system for containers e.g. goods wagons, pallets etc., utilises a stationary reading station and a coding arrangement carried on the container. A A.C. generator and coil located on the stationary reading unit induced a voltage in a coil carried on the container. A rectifier produces an output that triggers a level switch and a clock generator cycles the contents of a read-only-memory. The ROM output is used to modulate a high frequency oscillator output and a coil generates a field to induce a voltage in the sensing station coil. This signal is amplified, rectified and is checked with the required value.

Title: DC measuring transformer for high current values - measuring core held in unsaturated condition for accurate relationship
Inventor: HOELKEN UDO DR RER NAT
IPC: G01R19/20
Filed: 1974-11-06
Abstract: The d.c. measuring transformer for high current values has a measuring transmitting system whose core material is either of high permeability or constitutes a right-angled hysteresis logs. The current to be measured flows through the primary circuit, while the secondary contains an a.c. generator delivering the indicating current. To maintain the proportion between the current to be measured and the indicating current to a relationship of the number of windings on the primary and secondary coils the self-enclosed core (measuring core) is held in an unsaturated condition. The indicating current suffers no deep, non-symmetrical breaks and its polarity corresponds to that of the current to be measured.

Title: Preventing self ignition in soft polyurethane foam - by maintaining gas flow inside foam block during cooling processes
Inventor: HEIDELMANN GUENTHER ING GRAD
IPC: B29C44/56
Filed: 1974-11-29
Abstract: Self ignition is prevented in blocks on open-pored soft polyurethane foam by producing a gas flow inside the foam block, and maintaining this flow during the cooling processes. Method prevents fire risks during storage of large elongated blocks, as heat arising from exothermal reactions is rapidly removed. Specifically a chamber connected to a blower is arranged in a sealed manner at one end face of the foam block, and the other end face of the block is allowed to remain open. Alternatively, the other end face of the block is connected to a futher foam block by chambers placed over their end faces and those chambers are connected by pipes. The longitudinal faces of the foam blocks are provided with a sealed cover.

Title: Coin dispenser with removable box - is esp. for change machines and has automatic replenishing of coin stacks from box
Inventor: LANGKAIT OTTO
IPC: G07D1/02
Filed: 1975-07-04
Abstract: A coin dispenser with removable coin box is designed for automatic change machines and vending machines. The coin box has a mechanism with a motor to drive a disc which feeds coins from storage tubes into the dispenser. When the box is not in position on a supporting plate, locking pins engage in the disc and prevent it from rotating. When the box is placed on the plate and turned to lock it in its working position, a locking sleeve in the box is raised and this causes the locking pins to be released from the disc. The dispenser itself has a magnet locking system and an electrical height sensor which stops the disc drive in the coin box when the coin stacks reach a given height.

Title: IC engine with star shaped ignition chamber - regulates gas exchange by nozzle disc and impeller wheel
IPC: F02C5/12
Filed: 1975-07-23
Abstract: Engine has a rigid annular housing in which combustion chambers and cooling chambers are contained star shaped. The combustion chambers are open on both side faces and the cooling chambers are closed to all sides. The inlet disc and the impeller wheel are splined to the drive shaft which passes through the housing. The gas exchange is regulated by wedge shaped slots in the inlet disc and by slots formed as blade shaped jets in the impeller wheel. The propellant gas is pre-compressed in the ante chamber to flow through the intake regulator slots to the combustion chamber. The mixture is further compressed by the rotating inlet disc and ignited by a conventional method. The expanding gases escape to the final chamber, via the blade shaped jets in the impeller wheel, radially to the drive shaft. The process repeats itself continuously.

Title: Electric motor brush wear visual indicator - is flexible ribbon with indicator surface drawn past sight glass as brush wears
IPC: H01R39/58
Filed: 1975-09-02
Abstract: An electric motor particularly for work tools used on building sites, has an optical device to indicate brush wear. The wearing movement of the motor brush(es) is utilised to actuate a 'state of wear' indicator movable at least along an indicator scale. The indicator can be viewed through a sight glass facing opposite the indicator scale. A flexible ribbon or tape used as the indicator surface is connected at one end to the brush and is thus moved past the sight glass as the brush wears away. An indicator disc or indicator roller can be rotated by the wear movement of the brush.
