Patent DE-2741903-A1 (DE)
Title: Thermal waste air purifier for intermittent use - has air flow controller and heater ensuring easy restarting
Inventor: SCHROEDER WILLI DR PHIL
IPC: F23G7/06
Filed: 1977-09-17
Abstract: The thermal waste air purification system prevents cooling of the heat exchanger and associated heat transfer fluid in cold season. The air purification system is readily restarted after a longer standstill period. The hot water heat exchanger (4) has a controlled venetian blind arrangement (7) for controlling the flow of heat in the air. An additional heater can be provided. The waste air is directed from driers (1 and 3) by a waste air blower to the heat exchanger for preheater and subsequently into the burner. Energy for the drier is generated by the heater and purified air is rejected to the atmosphere. Excess heat heats high pressure water heater HDHW.

Title: Individual route control of road vehicles - uses road side transmitters sending data telegram to on-board receiver
Inventor: FINDEISEN BERND DIPL PHYS
IPC: G01C21/36
Filed: 1978-10-24
Abstract: The route control system is for road vehicles and uses transmitters located at the road side and on board receivers with course evaluation processing. The road side transmitter generates a data telegram consisting of a synchronisation component, an identification component and an information block consisting of target bit groups and directional bit groups. The direction bit groups contain information relating to the route taken at crossroads and branches etc. The on board receiver (RE) passes the signals to an error bit checking stage (TF). A comparator checks the telegram code with that held in memory. If coincidence occurs the route data in the telegram is compared (VG1, VG2) with the required route to be taken. If coincidence has not occurred, the next transmitter is identified and the associated data calculated.
Patent DE-2846428-A1 (DE)
Title: Heat exchanger with meandering heat pipe - mfd. by immersing pipe in water and casting cold setting resin on floating wax layer
Inventor: SCHIPPL KLAUSDIETER DIPL ING
IPC: B21D53/02
Filed: 1978-10-25
Abstract: The parent patent described a heat exchanger in which a heat pipe, filled with a working medium and bent to a meandering shape, is held in a partition between the hot medium and the cold medium. Such a register is mfd. by dipping the meandering heat pipe into water on which a layer of wax floats. The water is chilled until the wax sets and a cold-setting two component casting resin is poured on the wax. When set, the wax is removed by boiling water and the resin now forms the partition for the heat exchanger. This creates a very economical low-cost method for the mfr. of such a heat exchanger.

Title: Reciprocating plunger pump for hydraulic systems - has inlet valve sleeve adjustable to vary throughput according to pressure
Inventor: HAMMELMANN PAUL
IPC: F04B19/02

Patent DE-2912232-A1 (DE)
Title: Run=up circuit for brushless DC permanent magnet motor - employing rotor position sensors and pulse counting circuit for starting control
Inventor: BERGER HERMANN ING GRAD
IPC: H02P6/22
Filed: 1979-03-28
Abstract: The application is to a brushless dc motor with a three phase stator winding to which the dc supply is switched in rotation by a solid state control circuit. The stator also has a set of sensing coils whose number is chosen such that the number of output pulses per revolution is equal to the product of the number of phases and the number of rotor pole pairs. At the start the pulses from the position sensing coils are fed to a counter which in turn orders the application of current to the next stator phase in succession. At speed, control is transferred to a conventional controller. The arrangement gives a certain and controlled start regardless of the position in which the rotor is when at rest. The direction of run up is also correct although, depending on rotor initial position, the movement through one pole pitch in the reverse direction may occur initially.
