Abstract: ABSTRACT OF THE DISCLOSURE           An arrangement for modular mounting of a plurality of proximity switches comprises a plate of insulating material having a plurality of first conductive plates mounted on its front face.          A respective housing containing a switch circuit is replaceably mounted to the rear face of the plate of insulating material in correspondence with each first conductive plate.  Each housing contains a second conductive plate which, in conjunction with the associated first conductive plate, forms a parallel-plate capacitor.  The dielectric of the capacitor is formed by the plate of insulating material, a flat wall of the housing which the second conductive plate lines, and an air gap between the plate and the flat wall.  Touching of the second plate by a user varies the capacity of the capacitor thus generating a signal operating the circuit within the housing.  Since the two plates of the capacitor are mutually isolated, the user cannot experience an electric shock.  The housing may be mounted in the rear face of the plate of insulating material either direct or by way of an intermediate supporting frame.

Abstract: PRODUCTION OF RED PHOSPHORUS                 ABSTRACT OF THE DISCLOSURE Red phosphorus, usually in amorphous form, is obtained by heating white phosphorus at a temperature of between 250° and 590°C while the phosphorus is subjected to a pressure greater than the vapor pressure of white phosphorus at the heating temperature.  In this way, formation of a phosphorus vapor phase during the conversion is avoided. This may be achieved by feeding liquid white phosphorus into an extrusion head heated to the reaction temperature while sub-jecting the white phosphorus to a pressure in the extrusion head, the red phosphorus being removed into an inert atoms-phere.  Alternatively, molten white phosphorus in droplet form may be pumped into an inert immiscible heat exchange fluid at the reaction temperature and particulate red phosphorus separated from the fluid.

Abstract: PACK NITRIDING PROCESS FOR LOW ALLOY STEEL     ABSTRACT OF THE DISCLOSURE        A method of nitriding metal parts is disclosed.      A preferred mode requires burying the metal part to be treated in a body of vermiculite or other porous media containing urea.  Prior to burying, a controlled amount of an aqueous urea solution is absorbed into dry vermicu-lite; the water of the solution is removed by evaporation leaving a pasty urea substance coating or impregnating the grains of the vermiculite.  The urea-bearing vermicu-lite and buried part are heated in a closed container to a temperature at which the urea decomposes and releases gaseous nitrogen bearing gases.  Heating is then continued for about 4-8 hours at 700-1300°F (preferably 925-1050°F for 90% of the applications) to achieve a nitrided case on the part of the thickness desired, typically .002-.005" thick.

Abstract: ABSTRACT OF THE DISCLOSURE         A laundry dryer source of heat for providing warm gas to dry laundry is utilized to heat water for laundry washer use, and is particularly suited for coin operated laundries. In the illustrated embodiment each dryer has a gas burner and a water coil is in the flame area of the burner, the coils be-ing connected in circuit between a cool water outlet and a heated water inlet of a typical automatic water heater tank.  A water circulating system includes a pump or pumps for circulat-ing cool water from the tank through coils and returning heated water from the coils to the tank whenever any of the dryers are in operation.  One embodiment of the circulating system assures continuous water flow through the plurality of dryer water coils during heating operation by providing a substantially equal pressure differential between the cold water inlet and the hot water outlet of each of the coils.  A cross-over between hot and cold water headers may be provided intermediate the series of dryer coils for increasing the temperature of the hot water delivered to the hot water tank.  Since most laundry is promptly placed in a dryer after washing, during high or low capacity operation of the laundry the quantity of heated water is auto-matically regulated by dryer operation to the overall demand for hot water by the washers, the automatic water heater tank providing heated water during sudden surges in washer operation before the dryers are in operation sufficiently to supply the hot water.
