Title: Central heating system operating method - using heat storage vessel on each storey with thermostatic control to regulate supply of metered hot water from central boiler
Inventor: BROCKERHOFF HEINRICH ING GRAD
IPC: F24D11/00
Filed: 1979-02-08
Abstract: The central heating operating procedure is for a boiler furnace serving an apartment block. The circulatory system is divided into separate sections, e.g. for each flat, each having its own heat storage vessel supplied with the same amounts of heat at the same time. The boiler is subjected to a cooling phase after the storage vessel charging phase. When a heat storage vessel has cooled to an extent determined by a thermostatic control assigned to that heating section, it is recharged from the boiler and the amount and time is separately registered. The economical use of a single boiler is combined with precise individual comfort level setting and metering. Residual heat from the boiler during the cooling phase can be used. Unoccupied flats can be left at a heat level to prevent dampness etc.

Title: Cine projector with two driven spools - has take=off spool driven to relieve drag on take=up motor
Inventor: ACKERMANN MANFRED
IPC: G03B21/43
Filed: 1979-02-22
Abstract: A cine projector with separate drive motors on the two spools has a control circuit to monitor the current for the two motors w.rt. the mode of operation. For normal projection the supply reel runs on a freewheel with the torque supplied by the take-up spool motor. For fast wind or rewind, the supply spool is also driven to relieve the load on the take-up motor. The system requires low torque motors and a simple supply circuit. If the drag on the film and the supply reel exceeds a set value, the supply reel is driven, via the freewheel clutch, to hold the other motor inside set torque limits. The motor torques are monitored by a transistorised circuit linking both motors to the battery.
