Title: Two position controller for various physical quantities - has energy switching of high power temp. dependent switch for low hysteresis
Inventor: STUHL MANFRED
IPC: G05B11/16
Filed: 1977-08-06
Abstract: The two position controller for different physical parameters, e.g. humidity, temp. level speed etc. has a sensor which actuates a slow action electrical contact system and an output in the form of a thermal relay or temp. control circuit which constitutes a temp. dependent electrical spring contact system. It is designed to achieve the small switching hysteresis at high power and the sensor-switching mechanism separation of electronic systems using electromechanical components which are less expensive and less susceptible to noise than electronic systems. A two position controller with slow action or low spring force switching switches a low power resistor which produces auxiliary thermal energy which then actuates a temp. dependent electrical spring switch for high power.

Title: Composite bodies of light weight material - made from light aggregate and binder by compression with compressible layer between platen and mix
Inventor: DESTRIBATS JEAN-MARIE
IPC: C04B26/02

Patent DE-2751236-A1 (DE)
Inventor: NEUMANN GUENTER
IPC: G03D15/04
Filed: 1977-11-16
Abstract: The starting point is a bonding implement with a rotatably arranged and driven take-off roll (2), by means of which an adhesive tape (3) coated on one side with adhesive can be drawn off from a stock roll, with a rotatably arranged and driven drum which holds the adhesive tape on the non-adhesive side by means of a suction device, and with a separating device (6) acting onto the adhesive tape on the drum.

Title: Electric water flow heater control system - has heating coil divided into three sections, with two sections temp. controlled
IPC: F24H9/20
Filed: 1978-08-31
Abstract: The system for controlling the output temperature of a continuous electrically heated water supply system with a loading up to 22 kilowatts, has the eating coil divided into three sections. The main section has the heaviest load, the next section is smaller, and the last section is smaller still. The main section is not continuously switched off and on, in response to the water discharge temperature. This is switched in response to the flow of water. The other two sections are switched in response to the water discharge temperature, operated by separate temperature sensors. The switching frequency of the controller for the final section is higher than that of the controller for the intermediate section. The controllers operate through triacs with a zero voltage switch.
