Title: Arrangement for controlling the temperature of an enclosed space
IPC: F24F11/00
Filed: 1948-05-05
Abstract: 640,427. Automatic temperature control systems.. VAPOR HEATING CORPORATION. May 5, 1948, No. 12431. [Class 38 (iv)] In a temperature control system comprising a fan C blowing a stream of air into an enclosed space E, the space E is maintained at a predetermined comfort value of temperature and humidity by a thermostat F, while a second thermostat G limits the minimum temperature to which the space may fall. The fan C, energized continuously through a switch 20, forces air past a cooler A and a heater B into the space. E through vents 16. The cooler A is operated by a motor 29 and a relay valve 14, the energizing circuit for the motor and relay valve being through relay contact 26, operated by a relay 27, in turn energized through a circuit including the contacts of thermostat F. The thermostat F comprises a wet bulb 37 and a dry bulb 36 and operates to maintain a constant predetermined comfort value of, say, 72 F. and 100 per cent humidity, as shown in Fig. 2. If this value is exceeded the relay 27 becomes energized through contacts 40, 41 of the thermostat, thus energizing the cooler A, to return the temperature and humidity to the desired value. In order to ensure that the temperature of the space shall not fall below a minimum of 74 F. (Fig. 2), the heater B is incorporated. The heater B is controlled by a relay valve 18 energized through a relay contact 43 of a relay 44, in turn operated by a dry bulb thermostat G. Relay 44 is normally short-circuited through the thermostat contacts 55, 56 but upon a fall of temperature below 74 F. these contacts are broken, relay contact 43 is operated, and the heater becomes effective. In order to prevent hunting the thermostat G has an auxiliary heater 57 which is energized upon a fall of temperature below 74 F. through the relay contact 43. The heater 57 is arranged to cause an artificial rise in temperature of the thermostat G of about 1 F.

Title: Locking mechanism of a rotary shaft
IPC: F16D11/14
Filed: 1963-03-29
Abstract: 957,890. Locking rotary elements. STANDARD TELEPHONES & CABLES Ltd. March 29, 1963 [March 30, 1962], No. 12583/63. Heading F2E. [Also in Division B3] A device for wrapping wire around electric terminals includes a rotary shaft to which a wrapping bit is attached and rotary locking mechanism for the rotary shaft which locking mechanism comprises a first element fixed on and rotating with the shaft, a second non- rotatable element, means for holding the elements apart, the opposed faces of the elements having complementary contours including interlocking parts having locking surfaces which stop rotary motion in a fixed rotary position, and means for slidably moving said second element into or out of engagement with said first element. In operation depression of a trigger 19 causes compressed air to be delivered to a turbo-motor M and speed-reducing gear R rotating a shaft 8 to which a wire wrapping element 16 is attached. Exhaust air passes from the motor M through a large annular channel 21 between an element 1 secured to the shaft 8 and a casing 7, through a small annular channel 22 between a non-rotary element 2 and the casing 7 and out through a port 23. The arrangement thus allows compressed air to slide the element 2, against a spring 15, away from the element 1 to disengage abutting stops on the opposing faces of the elements 1, 2 and allow the shaft 8 to be rotated. The faces of the elements 1, 2 are formed with complementary interlocking sections A, B<SP>1</SP> of such angular extent that interlocking takes place in one angular position only. The sections B<SP>1</SP> are each divided into two parts C, D of different levels to aid the engagement of the elements 1 and 2. On release of the trigger 19 the spring 15 slides the element 2 back into engagement with the element 1 to stop rotation of the shaft 8, the shock of the stopping being absorbed by some rotation of the stator of the motor M which is freely mounted in the grip P and held only by a spring 5.

Abstract: Metals with a specific gravity greater than 4 are recovered from solutions, in which the metal is present as a cation, by contacting with a cation exchange resin having a cross-linked matrix and having bonded to said matrix acid groups as cation exchanging groups, said matrix being obtained by copolymerizing (1) a monoethylenically unsaturated monomer and (2) a polyethylenically unsaturated cross-linking agent which is copolymerizable with said monoethylenically unsaturated monomer, the copolymerization being conducted in solution in from 10 to 300%, based on the total weight of said polymer and said cross-linking agent, of an inert organic liquid which will dissolve the monomers but will not dissolve linear polymers of the monoethylenically unsaturated monomer, to produce a solid cross-linked non-proliferous copolymer linked by small veins, which veins have inert organic liquid occluded therein, and removing the occluded liquid from the polymer.  Such resins are described and claimed in Specification 894,391.  The resin may have as cation exchanging groups carboxylic acid, phosphonic acid, or phosphinic acid groups.  The resin may be regenerated by the use of dilute solutions of mineral acids or of organic acids, for example acetic acid.  Metals which may be recovered by the present process include Cu, Ag, Au, Zn, Ni, Co, Cr, U, Th, and the rare earths.  The solutions employed contain these metals as cations or cationic complexes, preferably at a concentration of normal or below.  The anions may be organic or inorganic acids, for example HCl, HBr, HF, H2SO4, H2SO3, HNO3, HCN, thiano-acetic, propionic, benzoic, citric or tartaric acid. Suitable complex formers include ammonia and amines, for example ethylene diamine, diethylene triamine, and propylene diamine.  The pH of the solution is preferably at least 4, especially in the range 5-12.  In examples, copper is recovered from a solution of cuprous chloride in ammonia and ammonium acetate, employing acetic acid for regeneration, from a Cu11 solution in ammonia, employing H2SO4 for regeneration, and Ni and U were recovered from acetate solutions, employing acetic acid for regeneration.
