Title: Rotary clothes hoist
IPC: B66D3/14
Filed: 1964-03-31
Abstract: 1,035,634. Rotary clothes hoist. HILLS HOISTS (MANUFACTURING) PTY. Ltd. March 31, 1964 [March 29, 1963], No. 13261/64. Heading A4U. [Also in Divisions B8 and F2]  A rotary clothes hoist comprises a lower stem 11, an opper elevating stem 12 and a gearbox housing 13. A crown wheel 19 is threadably engaged on a worm 17 and is rotated by a pinion 21 normally forced into engagement by a compression spring 55. A spring 42 normally holds a brake 41 against an upstanding skirt 26 of the crown wheel 19. The hoist may be raised or lowered by rotation of a handle 44 attached to a barrel of the pinion 21. A shaft 45, carrying the handle 44, also has a cam 52 so that twisting the handle about the longitudinal axis of the shaft compresses the spring 55 by withdrawing the pinion 21 from engagement with the crown wheel 19 at the same time releasing the brake 41. The weight of the hoist causes the crown wheel 19 to spin, but the rate of descent is controlled by a centrifugal brake comprising weights 30 pivoted on pins 29 and engaging a brake cup 33. The rate of descent may be controlled by a dashpot (see Division F2) (Fig. 4, not shown).

Abstract: 1,005,060. Gems. C. SIRAKIAN & FILS. March 31, 1964 [Jan. 31, 1964], No. 13279/64. Heading A3H. A method of joining two precious stones to produce a marquise shape comprises extending one pavilion in the direction of the table to reduce the height of the bezel by about one half and overlapping the extension with the bezel of the adjacent stone. The pavilion 6A of one stone A is extended beyond the pavilion edge 3A to produce a bezel 7A of height reduced to nearly a half. The extension overlaps the bezel 7B of the adjacent stone B in which the pavilion 6B extends to the lower part of the pavilion edge 3B. The stones join along the line 10.

Title: Improvements in or relating to method of and apparatus for converting carbon to electrical energy
IPC: H01M8/12
Filed: 1951-06-05
Abstract: 680,982. Batteries. PITTSBURGH CONSOLIDATION COAL CO. June 5,1951 [June 17, 1950], No. 13293/51. Class 53. A carbon-consuming battery of cells 44, 46 to which a mixture of hydrogen and carbon monoxide is fed and oxidized to produce current is enclosed in a receptacle 10 to which steam and a carbonaceous material are fed to produce the hydrogen-carbon monoxide mixture, the temperature in the receptacle being maintained by the heat evolved from the battery. Each cell comprises electrodes 32, 34 of different oxides of iron separated by a slab of electrolyte 36 consisting of a glass-like material comprising sodium silicate, monazite sand, tungsten trioxide and sodium carbonate. The walls of the cell container 38 are spaced from the electrodes to form gas passages 40, 42 through which air and the hydrogen-carbon monoxide mixture can be passed from inlet pipes 48 and 64, respectively. The cells in each of the groups 44, 46 are joined in parallel, the two groups being joined in series. The air passes to the pipe 48 from a conduit 50 and passes out from the cells through pipes 52 which lead into the cells of the group 46 from which the air passes out through a conduit 58. The mixture of hydrogen and carbon monoxide is prepared in the lower part of the vessel 10 which is provided with a grid 18 for supporting carbonaceous material introduced above the grid through a pipe 20. The carbonaceous material may be made by the low temperature carbonization of coal. Steam is passed into the vessel through a pipe 22, the mixed gases resulting from the reaction of the steam and carbonaceous material passing through a separator 24 and pipe 28 into the cells through conduits 64. The gases escape at 74 into a pipe 72 connected to pipe 58 from which the waste gases are discharged to any suitable place. Heat exchange between the pipe 58 and steam-pipe 22 and air-pipe 50 is provided by heat exchangers 64, 66. Current is drawn off from the battery through terminals 78, 80. Instead of using solid carbonaceous materials the mixture of hydrogen and carbon monoxide may be produced by the interaction of steam and methane in the presence of a nickel-alumina catalyst.

[A Specification was laid open to inspection under Sect. 91 of the Acts, May 26, 1945.] [Class 141] An undergarment of the pants or "briefs" type provided with a fly opening adapted to be kept closed by the tensions imposed on the garment during wear, comprises a back section 10 and front sections 11, 12 the front edges of which are cut at an angle so that they cross at a mid-point 14, 15 to provide overlapping parts 16, 17 above the crossing and a triangular space below the crossing. A two-ply crotch piece 21 secured by both plies to the back section at 19 and 22 has a triangular extension to occupy the space below the crossing. The outer ply is secured by one edge 25 to the front section 11, and the inner ply by one edge 27 to the front section 12, the other edges 26, 28 of the plies being left free to provide an overlapped fly opening. A binding 30a which is inextensible lengthwise is secured to the upper part of the front edge of the section 12 and to the free ply edge 28, and a similar binding 30b to the section 11 and the free edge 26. The tension on the bindings during wear of the garment tends to hold the plies of the crotch piece in overlapped relation. The sections 10-12 preferably are extensible circumferentially and the crotch piece may be extensible transversely or lengthwise and may include elastic threads. The garment may have an endless elastic waistband 29 as shown, or an inelastic band with fastening means.

[Class 40 (iii)] A tuned inductance and capacity are added to the coupling arm in that embodiment of the parent invention which is claimed in claim 7 of the parent Specification. Fig. 5 of the second Provisional Specification accompanying the parent Specification shows three meshes coupled by shunt capacities in combination with mutual inductances M1, M2, the effective shunt arms being tuned to the cut-off frequencies while the terminal-meshes are tuned to the midband frequency. According to the present invention, the leakage inductances which are effectively in the central series arm, and amount to (L2-M1) and (L3-M2) respectively, are neutralized by the insertion of additional inductance L5 such that the series arm is tuned to the mid-band frequency. The input impedance is made high, and the output combination C0, (L4-M2), may be slightly mistuned, to flatten the response at the middle and near the ends respectively of the pass band. The input leakage inductance (L1-M1) may be 30 or 40 per cent greater than the output leakage inductance L4-M2, while M1=M2. Instructions for trial-and-error adjustment are given and the effect of inherent resistance is considered in the Specification.

Abstract: 543,599. Regulating compressors. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., KERSHAW, A. G., and SIMMONS, A. W. Sept. 3, 1940, No. 13799. [Class 8 (i)] In a braking or other system comprising a common reservoir supplied by a number of compressors each provided with an automatic governor the compressors are caused to start simultaneously, regardless of precise adjustment of the governors, by caus ing the controlling pressure on each governor to be automatically reduced when a fall of pressure in the reservoir is initiated. Thereby each governor, while remaining under permanent control of the pressure in the receptacle, is temporarily caused to render effective the associated compressor, and all the compressors are brought into operation at the same time. In the apparatus shown in the Figure, each governor 2 is connected to a device 5 comprising a slide-valve 9 connected to a piston 14 mounted in a cylinder 11, 15 which communicates through pipes 12, 17 with the atmosphere and a brake-cylinder. Normally, a spring 16 holds the piston and slide-valve in the positions shown, and a small chamber 8 communicates with the atmosphere. When the brakes are applied, the piston and slide-valve are displaced, air flows from the governor into the cbamber 8, and the associated compressor is started. When the pressures in the governor and chamber become equal, control of the governor by the pressure in the common reservoir is restored. In systems wherein the pressure is reduced to apply the brakes, the piston 14 and slide-valve 9 are held in normal position by pressure in the train-pipe.
