Title: Improvements in cleaning or washing apparatus
IPC: D06F23/02
Filed: 1958-03-24
Abstract: 860,284. Washing and dry-cleaning machines. HAMMOND LAUNDRY-CLEANING MACHINERY & SUPPLY CO. Inc. March 24, 1958 [March 25, 1957], No. 9445/58. Class 138 (2). [Also in Group XXIV] A washing machine comprises an outer container for liquid and an inner container for articles to be washed and a rigidly mounted driving shaft connected by a flexible coupling to the driven shaft of the inner container, provision being made for movement of said containers lateral of the axis of the driven shaft. As shown in Fig. 3, a constant speed motor D has a variable diameter V pulley 67 shown in detail in Fig. 9. To vary the speed of drive the motor is raised or lowered by the action of link 106 on platform 104 pivoted at 105. This causes halves 68 and 69 of pulley 67 to move together or apart, being urged together by springs 74 and 73. The drive from pulley 67 is communicated to belt 79 and pulley 80 fast with a small pulley 81 both free to rotate on driving shaft 41. When driven at low speed by belt 79 the drive is transmitted from pulley 80 to 81 and via belt 82 to large pulley 83 coupled by a centrifugal clutch to small pulley 86, the arrangement of this clutch being such that it is engaged at low speed but disengages when pulley 83 is driven at a higher speed. The drive from pulley 86 is conveyed by twin belts 96 to pulley 97 fast on driving shaft 41 thus driving the inner container slowly for washing purposes. When high-speed drive for spin drying is required, platform 104 is raised and belt 79 makes contact with the periphery of pulley 67 and belt 79 drives pulley 80 at high speed. This causes a centrifugal clutch attached to pulley 80 to come into engagement with clutch drum 99 on pulley 97 and as a result drive is communicated directly from pulley 80 to shaft 41. A flexible coupling F transmits the drive from shaft 41 to stub shaft 36 and container C. Coupling F comprises a rigid disc 44 bolted to a flexible disc 46 bolted to another rigid disc 50 to which are welded torque transmitting tubes 54. The other end of the tubes is welded to a second flexible coupling element comprised of rigid disc 55, flexible disc 56 and rigid disc 60. During the centrifuging operation the outer and inner container are free to vibrate together under the control of springs 21 and dampers 23. The speed of the drive is controlled by a fluid system comprising a strut 106 pivoted at 107 to a piston-rod 108 acting on a piston 110 in cylinder 109. A centrifugal pump 115 provides a source of liquid pressure which, when required, is supplied to cylinder 109, raising piston 110 and platform 104, and engaging high-speed drive.

Title: Improvements relating to defrosting refrigerating coils or tubes
IPC: F25B47/02
Filed: 1949-04-08
Abstract: 672,249. Fluid-actuated valves. YORK SHIPLEY, Ltd., and HEAP, E. M. July 7, 1950 [April 8, 1949], No. 9609/49. Class 135 [Also in Group XIII] In a valve (Fig. 2) for connecting a liquid pipe 2 or a high-pressure gas pipe 4 to a pipe 1, the liquid normally flows through a valve orifice 14, the valve element 13 of which is formed on a piston 12 retracted by a Spring 23 acting on a stationary member 16 and on cross-pins 22 on the piston. In this position ports 24 in the piston are closed by the cylinder wall. When a cock in the'pipe 4 is opened, high-pressure gas enters the interior of the piston and forces it up to close the valve 13, 14, and open the ports 24 through which the high-pressure gas flows to the pipe 1. The ports 24 have a throttling action to maintain a pressure difference across the piston. The valve 13, 14 may be manually closed by turning a handle 17 on a rod 15 screwing into the casing and carrying at its upper end the member 16 which abuts the top of the piston to move it. In a somewhat, similar valve (Fig. 3), the ports 24 are omitted and the high-pressure gas entering by a pipe 5 operates a piston 12b to close a valve 13b, 14b between pipes 1 and 3 and divert the liquid through a manuallyadjustable throttling valve 32, 37 between the pipes 1 and 3.

Patent GB-1504796-A (GB)
Title: Spin-dyeing of acid-modified acrylonitrile homopolymers and copolymers
IPC: C08L33/02
Filed: 1975-03-10
Abstract: There is described a process for spin-dyeing acid-modified polymers or blend polymers of acrylonitrile in which basic dyes are incorporated in the spinning solutions of the polymers. These dyes are present as free dye bases and contain at least one primary, secondary or tertiary amino group, a hydrazino, hydrazono or guanidino group as the basic group, this basic group not being attached to an aromatic radical. The basic group, for example in the form of the secondary or tertiary amino group, can also be part of an aromatic, unsaturated or hydrogenated heterocycle. The free dye bases used in the spinning solutions can belong to a wide range of classes of dyes, for example to the azo, anthraquinone, phthalocyanine, benzoxanthene and nitro series. The dyes can be dissolved in the solvent in which the polymer too is dissolved, and the homogenised spinning solution prepared therefrom can be spun by the wet or dry spinning method. The advantage of using the dye bases mentioned in the spinning process is that foreign salts are absent, thus producing completely transparent, speck-free spinning solutions which do not cause clogging or mechanical wear of the spinnerets, which happens in particular when pigments are used. The materials spun therefrom have very high wet fastness and extremely good rub fastness. Their light fastness is substantially improved compared with dyeings obtained on the colourless polymer fibres by dyeing methods from aqueous or aqueous-organic dyeing liquors and dyeing baths.

Title: Improvements in and relating to photoconductive cells
IPC: H01L31/08
Filed: 1946-03-30
Abstract: 610,362. Light-sensitive cells. STARKIEWICZ, J., SIMPSON, O., STOW, R. L. and BUCKINGHAM, J. March 30, 1946, No. 9944. [Class 40 (iii)] A sensitised layer of lead sulphide is formed in a photo-conductive cell by heating the layer in the presence of oxygen to a temperature of 500‹ C., while extracting sulphur dioxide at a controlled rate. The cell, which consists of a double-walled glass cylinder closed at one end, has a grid of graphite electrode lines formed on the inner end wall on which a layer of lead sulphide is formed by sublimation and condensation (Figs. 1 and 2, not shown). Apparatus for forming and sensitising such layers is shown in Fig. 3 and comprises an electric oven f containing the cell a which is sealed on the end of a tubular stem h provided with a constriction h<1> and a U-bend to which a flask i of liquid air can be applied. The stem h is connected via a three-way tap j, to a vacuum system including a liquid air condensation trap k and an oxygen reservoir l. The cell, which initially contains a suitable amount of powdered lead sulphide, is evacuated and heated to 600‹ C. until the lead sulphide sublimes, the flask of liquid air being then applied to the U-tube to extract and trap by condensation all SO2 subsequently produced. Oxygen is now admitted to the cell and the heating continued at 560‹ C. to 600‹ C. for a further period depending on the pressure of the oxygen and the rate at which SO2 is extracted (determined by the size of the constriction h<1>). The oxygen is then pumped out and the lead sulphide caused to condense on the window of the cell by means.of a cool air blast applied through a nozzle n. The cell is next cooled to room temperature and a gasair flame applied'through nozzle n causes the lead sulphide to sublime and condense as a layer covering the electrode grid on the inner end wall which is cooled by an air blast applied through nozzle n<1>, The oxidised layer is then sensitised by heating in oxygen at a pressure of 0.2 mm. Hg. a temperature of 450‹ C. being reached in two minutes during which the layer conductivity, after an initial increase, passes through a minimum at about 400‹ C. and again increases until the treatment is terminated, when the temperature has reached about 450‹ C. Further treatment consists of exposing the layer, in the presence of oxygen, to traces of SO2' which.is introduced by removing the liquid air flask i from the U-bend. Alternative further treatment consists either in heating the evacuated cell to 250‹ C. at which temperature the conductivity is a minimum and the photo-sensitivity a maximum or, in gently heating the cell to about 250‹ C. with oxygen present. An improvement in sensitivity and a decrease in conductivity is stated to occur after the cell is finally evacuated and sealed.
