Title: Distilled water recovery or prepn in refrigerators - using heat supplied by motor or moist, warm air when door is open
IPC: F25D21/14
Filed: 1973-09-14
Abstract: Pure, non-calcareous water is recovered from a refrigerator by condensing water on the cooling coil in the ice box from the warm, moist air entering when the door is opened frequently. When de-frosting is effected manually, or (semi-)automatically this water is recovered for use as distilled water in electric accumulators, steam irons and electric humidifiers. It can also be distilled in the refrigerator using the heat generated in the motor driving the freezing system. The vapn. tank of the motor has a cover with movable shutters; these are controlled from the outside by a pull-knob and cables. The cover is fitted with a tube with an evapn. header also fitted with shutterS. A funnel is built into the wall of the refrigerator and is connected to the evapn. tank of the motor by a tube. The recovery tank is situated below the ice box and is connected to a reservoir, fitted with a tap operated from the outside. When distilled water is required, the motor tank is filled with water; the vapour produced passes out through the evapn. header and condenses and freezes on the cooling coil. On de-frosting the ice melts and the water flows into the reservoir from which it can be drawn off through the tap. Very pure water for use in accumulators, for the care of the skin and hair and for electrical appts. operating with water, can be obtd. at no cost. Only simple modifications to the refrigerator are needed.

Patent FR-2268406-A1 (FR)
Title: Double frequency telephone signalling - recognises signal for set frequency voltage relationship
IPC: H04Q1/46
Filed: 1974-04-16
Abstract: This telephone signalling system uses a two frequency signal located in the upper speech frequency band with the frequencies separated by several hundred hertz. The sinusoidal signals are equal in amplitude and are chopped at the required signalling rate. They are recognised as signalling voltages if they maintain this voltage relationship, say 3dB at a threshold of -20 dB, for periods of 10 ms and are therefore immune from false interpretation as noise and speech signals. The signalling circuits may be kept across the line during speech periods and overcome the problems, such as low frequency noise, that are normally experienced when these are permanently in circuit.

Title: Tungsten carbide and nickel phosphide coated die - with longer life for aluminium extrusion
IPC: B21C25/00
Filed: 1976-11-12
Abstract: The die comprises a steel support the work surfaces of which are coated with a layer contg. Ni phosphide, the phosphide layer itself being coated with a WC-base layer or a layer comprising mainly a mixt. of WC and W. The layer contg. WC reduces adhesion between Al and the die surface, minimising roughening of the extruded metal. The intermediate layer between the WC layer and the steel acts as a crack-propagation barrier. The WC layer can be removed and replaced by dissolving in an aq. soln. of NaOH and H2O2 at room temp. Since NaOH alone only reacts slowly with the WC layer it can be used for cleaning i.e. removal of residual Al.
