Title: A gas blast circuit breaker
IPC: H01H33/14
Filed: 1965-11-24
Abstract: 1,098,380. Gas blast switches; electrically released switches. GENERAL ELECTRIC CO. Nov. 24, 1965 [Dec. 29, 1964 (2)], No. 49858/65. Heading H2B. A gas blast circuit breaker has a blast valve assembly 36 movable by gas pressure under the control of a pilot valve 70, the blast valve 36 acting upon a crosshead 30 to move the contacts 24 to the open position where they are held by a latch (130) (Figs. 5, 6, not shown) engaging with a roller 132. The crosshead 30 is attached to damper pistons 60, 150 which control the opening and closing movements of the contacts respectively. A control rod 104 extends through the crosshead 30; this rod 104 is coupled to a control linkage (Figs. 5, 6, not shown) which is moved to the open position by a pneumatic cylinder (190) and held by a latch (140) which is releasable by a solenoid (144) to close the breaker. To open the breaker rod 104 is drawn rapidly downwards taking with it a piston 102; a partial vacuum thus created between them causes a second piston 100 to follow piston 102 thus opening the pilot valve 70. Compressed gas then flows from the containing tank (Fig. 1, not shown) through channels 56, 57, 73 to a space 66 above a piston part 65 of the blast valve 36, the other side 109 of piston 65 is vented through channels 110, 84. As piston 102 moves down compressed gas enters between pistons 102, 100 through channel 58 but valve 70 is held open, by compressed gas passing through a channel 80 to a space 78 above a piston 75 attached to the movable valve member 71, until blast valve 36 reaches its fully open position when a channel 92 supplies gas through an adjustable valve 108 to the other side of piston 75 permitting pilot valve 70 to reclose under spring 77 and the blast valve 36 to reclose under a number of tight springs (119) (Fig. 2, not shown). When rod 104 is returned to the closed position by releasing latch (140) a further linkage releases the main latch 130 and the contacts reclose under the action of compressed gas on the underside of the crosshead 30. All the control channels are vented while the contacts are closed.

Title: Air cooling system for below freezing temperatures
Inventor: DAVIDSON ARTHUR RAMSEY
IPC: F25D19/04
Filed: 1963-12-23
Abstract: 1,065,330. Refrigerators. LAMB-WESTON Inc. Dec. 23, 1963, No. 50634/63. Heading F4H. A cold storage room is refrigerated by a plurality of refrigerating units each comprising an insulated compartment 64 containing the compressor 78 and condenser 86 of a refrigerating system, evaporators 88, 90 mounted outside the compartment and fans 94 for drawing air over the evaporators and discharging it into the interior of the cold storage room. Because of the insulation the heat developed by the compressor, and if necessary auxiliary heating means, is sufficient to maintain an adequate temperature within the compartment 64 to permit operation of the component therein when the compartment is located within the refrigerated space. The units are preferably suspended at intervals beneath the roof of the room (Figs. 1 to 5, not shown), but may be mounted on movable supporting structure or disposed adjacent door or other wall openings through which air may be discharged after cooling the condenser. Refrigerating system (Fig. 10 not shown). Refrigerant from the two-stage compressor (78) passes via line (108) and check valve (110) to the condenser (86), which is water-cooled, and thence via line (112), cooler (80) and line (126) to parallel lines (128, 130) which supply refrigerant to respective evaporators (90, 88) and include expansion valves (134, 140). Refrigerant from the evaporators returns to the compressor via parallel lines (138, 144), line (146), receiver (84) and line (100). Cooler (80) is cooled by refrigerant drawn from line (112) through a line (116) containing an expansion valve controlled by a thermal bulb (122) mounted on the pipe (104) connecting the compressor stages, refrigerant vapour from the cooler being returned to line (104) via line (124). Defrosting.-One evaporator is defrosted, while the other remains operative, at intervals determined by a timer (186). For example, evaporator (88) is defrosted by closing a valve (139) in line (130) and opening a valve (166) so that hot gaseous refrigerant from line (108) passes to the evaporator via lines (156, 162). A valve (170) in line (144) is closed to divert refrigerant from the evaporator through a line (173) leading to a header (180) whence gaseous refrigerant passes to line (112) via line (180) and liquid refrigerant passes to a receiver (82) via line (178). Preferably the timer (186) controls all of the units sequentially so that not more than one or two is or are being defrosted at any one time. Electric heaters may be used to supplement the hot-gas defrosting. Defrost water is collected in pans 97 (Fig. 8).

Title: An improved process of, and apparatus for, the manufacture of products of sprayed metal or having a coating so formed
Inventor: HAND STANLEY ARTHUR
IPC: C23C4/08
Filed: 1965-12-02
Abstract: In metal spraying a flux is incorporated into the stream of gas and metal particles from the spray gun by feeding it to the gun as droplets of liquid suspended in a carrier gas, as a gas mixed with a carrier gas or in both such forms.  The carrier gas may be a fuel gas, an oxidant, or both may be used to carry the flux. Alternatively a separate gas stream may be employed to carry the flux, or where a plasma flame or arc- or induction-heated propulsive gas is employed the flux may be carried by the plasma-forming or propulsive gas.  The flux is preferably a volatile liquid, and is incorporated into the carrier gas by entrainment from a wick Fig. 3 (not shown) or by bubbling the gas through it.  Where the metal sprayed is copper, or an alloy of copper such as phosphor bronze, aluminium bronze or brass, an alkyl borate may be employed as the flux. Methyl-, ethyl-, propyl- and isopropyl-borate, or any combination of these which form a volatile liquid fluxing agent may be used.  Alternatively any of them may be mixed with a suitable alcohol such as an alkyl alcohol. Where aluminium or its alloys is sprayed the fluxing agent may be a volatile liquid containing a fluoride radical.  The invention is stated to be applicable to the spraying of ferrous metals and of nickel and its alloys, the fluxing agent being in each case a volatile liquid which inhibits oxidation of the metal.

A feeding wheel 24 feeds the wrappers 16 to holders 21a on an indexing wheel 21 which is driven via a star wheel 26 to carry the wrappers 16 past a twisting station 19 and a pressing station 20. The twisting station 19 comprises a twisting apparatus 18 which consists of a mandrel 29 and clamping jaws 35 connected to a shaft 31 which is reciprocated by means of a cam 43 and is rotated by means of a chain 55. The mandrel 29 and the jaws 35 are enclosed in a control ring 37 which is reciprocated via a linkage 45, 46, and 47 by a cam 53. The pressing station comprises a pressing head 64 heated by an electric resistance 66 and mounted on a shaft 63 which is reciprocated by the cam 53. The shaft 63 carries a wheel 56 around which the chain 55 is trained, and also carries a pinion 57 engaged by a toothed segment 37 rotated by a cam 62. In operation, the mandrel 29 and the jaws 35 are advanced towards the wrapper 13 so that the jaws 35 engage the control ring 37 and are opened thereby, against the action of coil springs 36. The control ring 37 is then advanced, together with the mandrel 29, so that the mandrel 29 enters the wrapper 15 which is held thereagainst by the jaws 35 which are closed by the springs 36. The mandrel 29 is then rotated to form the neck 15e and the rosette 15c, the mandrel being advanced to compensate for the shortening of the wrapper due to neck formation. After rotation, the mandrel 29 is again advanced with the ring 37 held stationary so that the jaws 35 open to release the rosette 15c and a dished portion 29a of the mandrel partially presses the rosette, Fig. 7. The indexing wheel 21 then carries the wrapper 15 to the pressing station where the rotary pressing head 64 presses the rosette against the end of the tampon. The indexing wheel 21 carries radially directed ramming tools (70, Fig. 11) which, at the twisting station 19, are urged outwardly by a fixed cam (77) to engage longitudinal grooves in the tampon to prevent axial movement and rotation thereof. At the pressing station the tools (70) are only urged so far as to prevent rotation of the tampon.

Abstract: 1,194,346. Producing edible flour from comminuted oil seed meats. UNGA Ltd. 16 Oct., 1968 [21 Nov., 1967], No. 53015/67. Heading A2Q. Edible flour, e.g. for use as animal fodder, is produced from oil seed meats, such as comminuted cottonseed or groundnuts, by treating the meats with a solvent consisting of, or containing as the major constituent, methyl acetate, to extract unwanted components, such as gossypol, in the case of cottonseed, and aflatoxin, in the case of groundnuts, together with a high percentage of the oil. Preferably, water or/and methanol are added to the methyl acetate, the amount of water not exceeding 8¢ per cent by weight and the amount of methanol not exceeding 40 per cent by weight. The preferred amount of methanol is between 15 and 20 per cent, a preferred solvent consisting of 81 parts of methyl acetate and 19 parts of methanol. By this means, and by employing four extractions of about 15 minutes each, the gossypol content of a cottonseed sample was reduced to 0.112 per cent by weight and the oil content to 0.5 per cent by weight. The addition of 1¢ to 6¢ parts of water the gossypol content was reduced further to 0.057 per cent, but the oil content was then reduced only to 1.0 per cent. A countercurrent method of extraction was found to advantageous. A groundnut meat sample was given four extractions with a mixture of 80 parts methyl acetate and 20 parts methanol, the first extraction being combined with grinding with the addition of a little water. The resultant meal was found to contain no detectable aflatoxin; the oil content was 4.4 per cent.
