Abstract: ABSTRACT OF THE DISCLOSURE         A method of preparing antimony pentoxide from solids containing antimony sulfides is described.  The method comprises the steps of:  (a)  leaching the antimony values from the solids with an aqueous potassium hydroxide solution to form an anti-mony containing solution and a gangue, (b) oxidizing the anti-mony present in the leaching solution to a pentavalent antimony, (c)  separating the oxidized solution from the gangue, and (d) adding an inorganic acid to the solution to reduce the pH of the solution to about 5-7 whereby antimony pentoxide is pre-cipitated from the solution.  In a preferred embodiment, the oxidation of the solution is conducted in the presence of a catalyst which comprises a water-soluble copper salt, a quinone, a hydroquinone or mixtures of one or more of these.

Abstract: ABSTRACT             "Reciprocating Heat Engine"       A reciprocating external combustion engine wherein energy is supplied to a working end space of the engine by direct injection into the cylinder of liquid water at a high temperature and pressure.  The water acts as a heat-transfer medium.  Some of the liquid water spontaneously vapourises on injection, driving the piston.  Liquid water is exhausted from the  cylinder and recycled to an external heat exchanger for reheating prior to reinjection.  The engine is capable of an efficiency greater than that of the Rankin cycle.

Abstract: A  B  S  T  R  A  C  T            For measuring the volume of a particle, for example in ore sorting, the particle is caused to move past radiators which illuminate the particle in two transverse directions. Detectors provide measures of the dimensions of the particle in the transverse directions in each of a number of adjacent zones which extend  through the particle in its direction of movement.   For each zone a volume measurement is derived from the product of the dimensional measurements and the various volume measurements are accumulated to obtain the final volume measurement.            The dimensional measurements may be made in each zone in four or more transverse directions, and may be made by means of scanning cameras to obtain a more accurate final volume measurement.

Abstract: AIR SUPPLY SYSTEM FOR SPAS        Abstract An air supply system for spas provides protection against motor short circuits caused by water backflowing through the air supply line to the housing containing the motor and blower.  A moisture-proof partition isolates the motor from direct exposure to the air supply line.  The partition and the blower air intake tube are arranged to prevent water from reaching the motor, unless such water first flows through the outlet ports of the blower and then through the blower air intake tube.  The blower ports dissipate the water backflow pressure, thereby preventing backflow surges of short duration from reaching the motor.  In addition, the inlet end of the air intake tube extends vertically well above the bottom of the motor to provide a static head to offset the backflow pressure of water in the air intake tube.     In an alternative embodiment, a drain is provided by ducting the air intake tube to the exterior of the housing to positively prevent water from reaching the motor.
