Title: Liquid level monitor for refrigerating equipment - using temperature transducers in voltage monitoring circuit to check threshold levels
Inventor: HANSEN HERBERT
IPC: G01F23/24
Filed: 1975-09-10
Abstract: The method of monitoring liquid levels in refrigerating equipment uses temperature transducers and an associated circuit to check that the liquid level lies within given thresholds. The circuit consists of two temperature dependent resistors in series with two other resistors, and a voltage monitoring circuit consisting of a comparator, a flip flop and a relay. The temperature dependent resistors are mounted in the equipment so that both are normally in the liquid or in the vapour, but if the liquid level falls below or rises above set threshold, one resistor is then immersed and the other not, with the result that the flip flop changes state and the relay contacts open. A number of auxiliary transistors form a circuit which monitors whether any open or short circuit occurs in the lines connected to the temperature dependent resistors.

Title: Recuperative heat exchanger for ventilation systems - has heat exchangers rotated to achieve self cleaning action
Inventor: VICKTOR HORST DIPL ING
IPC: F28D19/00
Filed: 1975-10-28
Abstract: A heat exchanger (1) in an exhaust air duct (3) transfers heat to water in counterflow with the air. The water goes to a similar heat exchanger (2) in the supply air duct (4) where it gives up heat in counterflow to the air. The fixed water pipes (5, 8) are jointed to the heat exchangers by flexible connections (6, 13). At periodic intervals the heat exchangers are rotated through 180 deg. so that the flowing onto them strikes the opposite face. At the same time the water flow is reversed by bypass valves so that it is still in counterflow to the air through the exchangers. As the air flow is laminar, dust settles on the inlet only and is dislodged when the flow reverses.
