Title: Improvement in methods and apparatus for producing vacuums
IPC: F04F9/00
Filed: 1943-03-08
Abstract: 566,814. High vacuum jet pumps. DISTILLATION PRODUCTS, Inc. March 8, 1943, No. 3700. Convention date, May 20, 1942. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 21, 1943]. [Class 71] High vacua are produced by vaporizing a stable organic liquid and using the vapour in a jet in aspirating relation 'to a space to be evacuated, the vapour being given a velocity at least 50 per cent of the velocity of mean square of the molecules being evacuated. The liquids may be fractions derived from hydrocarbons ranging from winter grade crank-case oil to fuel oil. Fig. 1 shows apparatus employed, wherein the liquid is vaporized in a boiler 10A heated by a steam coil and passes to the jet 12A through a conduit IIA heated to prevent condensation from which it issues at the required velocity. The gases are entrained from a chamber 13A connected to the fine vacuum pipe, and the jet is delivered through a zonally cooled diffuser jet 17A to a condenser 21A from which the recovered working liquid is returned to the boiler, while the evacuated gas passes to the similarly constructed next stage pump and so to the third stage pump connected to a force vacuum pump. In another form, the second and third stage diffuser jets have gritters which collect the least volatile and first condensed liquid and return it to the first and second stage boilers, which are connected by trapped overflow pipes to the succeeding boilers. The third stage pump may deliver to the top of a rectifying column in which crude liquid is treated for supply to the third stage boiler ; the boilers and the boiler of the rectifier are connected by pipes controlled by float-actuated valves ; the lighter fractions travel through the condensers to the later stages while the heavier fractions flow in the reverse direction to the first stage boiler and a boiler connected with it from which the excess of non-volatiles is drawn off. Fig. 5 shows one form of pump employing parallel jets connected to a .vapour box 105 separated for thermal insulation from the outer wall and delivering to diffuser jets cooled in their upper parts by a liquid bath 112 and in their lower parts by air, and opening into a cooled reservoir 85 leading to an annular condenser ; liquid is returned to the boiler by way of a separator 99 and pump 101. Several such pumps may be arranged in series.

Abstract: 370,549. Supply system for consuming devices. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Kearsley, W. K. ; 1606, Randolph Road, Schenectady, New York, U.S.A.) Feb. 6, 1931, No. 3832. Convention date, Feb. 6, 1930. [Class 38 (iv).] Systems depending on static transformers.-In an A.C. system in which a unilaterally conducting load such as an X-ray device is supplied from a transformer, the high open-circuit voltage which tends to occur during the half-wave intervals when the load is nonconductive is reduced by putting a rectifier in the primary circuit of the transformer. An X-ray tube 6, Fig. 1, is supplied from A.C. mains 24, 241, through a step-up transformer 1 which has a rectifier valve 18 in series with the primary. In a modification shown in Fig. 2 the rectifier is of a Thyratron valve 35 the grid potential of which is determined by the voltage of the battery 37 and the alternating voltage across the resistance 38 when switches 41, 26 are closed. Switch 41 is of press-button type. The circuit is operative only when this switch is closed. Reference has been directed by the Comptroller to Specification 9089/06, [Class 38, Electricity, Regulating &c.].
Patent GB-972218-A (GB)
Title: Automatic sampler for sheet handling apparatus
IPC: B65H29/58
Filed: 1962-02-01
Abstract: 972,218. Delivering sheets. CONSOLIDATED PAPERS Inc. Feb. 1, 1962 [Feb. 15, 1961], No. 3836/62. Heading B6H. Relates to apparatus for converting a paper web into reams of cut sheets and automatically extracting or diverting sample sheets from the delivery from the cutter, for inspection. According to the invention, sheets are diverted from the high speed delivery on to a carrier operating at least at the speed of the delivery by immediately and continuously pressing the leading edge into intimate supported contact with the carrier and continuously maintaining the leading edge and progressive portions of the rest of the sheet in such contact with the carrier throughout the area of diversion. Thus the sheets are diverted without delay or buckling. Sheets cut by a knife on a roller 21, Fig. 2, from a web supplied from a roll 20 are passed by tapes 48, 49, 50 to tapes 45, 47 and thence to slower moving tapes 71 which cause them to overlap, and into a layboy. Selected sheets are diverted by a pivoted gate 60 to tapes 44, 45 and thence to a layboy 150, Fig. 1a. The diverted sheets are pressed down against the tapes 50 by air jets 61, and when a sheet is diverted the tapes 71 are stopped by releasing a clutch and applying a brake. The sheets are assisted into the layboys by air from nozzles 64, 62. The jets 61, gate 60, clutch and brake are operated at predetermined times by electrical control means actuated by switches 98, 99 (not shown), and 115, and a photoelectric cell 125. The switches 98, 99 are operated by cams 96, 97 on a shaft 95 rotated from the shaft of the roller 21, the cams being angularly set with respect to the knife by a pawl and ratchet mechanism on the roller shaft. The switch 115 is operated by buttons 113 selectively placed on a belt 111 driven from the roller shaft. The switches control the jets 61 and gate 60. The photoelectric cell senses diverted sheets and controls the brake and clutch, which alternatively can be controlled mechanically or electromechanically by two further cams on a shaft driven from the shaft 95 and angularly set by a further pawl and ratchet mechanism on the shaft 95. The layboy 150 comprises a plurality of longitudinal slots up through each of which protrudes a finger 153, the fingers being laterally aligned and pre-set according to sheet length to act as front stops. Drag ropes 163 slow down the sheets as they enter. The layboy is movable laterally on wheels 167 to a position outside the machine to allow inspection of the diverted sheets.

Abstract: 122,313. Commin, F. J. March 7, 1918. Compound paper; paper, treating with special materials.-Sheets for making boxes, cisterns, doors, bottle caps, and other articles are made from finished or unfinished paper by sprinkling finely ground or powdered pitch to the required thickness on damp unfinished paper or on paper which has been coated with size or other glutinous matter, superimposing the sheets, pressing them together, passing through an oven at such a rate as to liquefy the pitch, then subjecting to considerable pressure in an hydraulic press. The articles produced may be rendered fire-resisting by using asbestos paper, paper treated with alum, or papers made with fillers of magnesite, chalk, silica, cement, clay, or the like. With paper made from straw, wood pulp, rags, or the like, pitch of low melting-point is used. The sheets or articles may be coloured with brick dust or the like, or they may be covered with coloured papers or powders before the final pressing in moulds. In making boxes, cisterns, and the like, the material may be pressed flat, cut, and subsequently re-heated, and re-pressed, the parts of the material being jointed together by the second pressing operation.

Abstract: 451,663. Television. WILSON, J. C., 24, Whitworth Park Mansions, Moss Lane East, Manchester, and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Feb. 8, 1935, No. 4127. [Class 40 (iii)] The scene 1, Fig. 1, is scanned to generate picture signals in a cell 3 while a cell 6 views a portion 7 of the scene, the signal from the cell 6 being used to control the gain of the picture signal amplifier 9, so that as the general illumination of the scene varies, as the result of variation in the illuminating source, the gain of the amplifier 9 is inversely varied. A further cell 5 may view the scene as a whole to provide a signal proportional to the total light reflected. This signal is used to control the picture signal amplifier 9 so as to maintain the general brightness of the receiver picture irrespective of the picture content. Alternatively, this latter signal may be derived from the output of cell 3. The signals from cells 5, 6 may be applied to a potentiometer 11, 12, Fig. 2, the tappings from which conduct the net correcting signal to the amplifier 9.

Title: An improved spherical inflatable, athletic game ball and method of making same
IPC: A63B41/08
Filed: 1940-03-06
Abstract: 538,809. Balls for games. REACH, M. B. March 6, 1940, Nos. 4251 and 4252. Convention dates, March 6, 1939, and June 5, 1939. [Class 132 (ii)] A spherical inflatable ball for games is built up on a wax or other frangible form mainly of superposed cord windings in great circles, by superposing cemented layers of the windings and severing the layers successively to form an opening through which the frangible form may be removed and an inflatable bladder inserted, the opening being afterwards permanently closed by patches (for example the severed portions) conforming substantially in strength with the main wall, cover panels (for example of leather) being finally cemented to the exterior. In constructing one form of the ball, tubular stockinette 2, Fig. 2, is treated with cement and drawn tightly over the wax form. Its ends are twisted and cut off to leave openings to each of which a patch 3 of balloon cloth is cemented. A layer 4 of card wound in great circles is applied. After the cement has dried, a cut 5 is made through the winding, the balloon cloth and the stockinette, thereby removing a patch but leaving an annulus of balloon cloth as a reinforcement to the cut ends of the winding cord. A plate of metal is now placed over the resulting gap and a second winding 8 of cord is added, and a second but slightly larger patch is cut out, the metal plate being removed. Similarly a third cord winding 10 is applied and a larger patch removed by incisions 10a. The wax form is removed by melting or breaking and a bladder a is inserted and inflated, the valve stem extending through any suitable opening. The patches previously removed are replaced and cemented to form a composite structure. The end windings are applied in a winding machine. Leather sections b, slightly separated, are finally applied to the exterior. In a modification, Fig. 4, a piece of balloon cloth 3b, 8b or 10b is combined with each layer of cord winding, and the patches instead of being completely severed have retaining hinge portions. A layer 3d of balloon cloth is inserted between the outer cord winding and the leather cover. sections. In a modification, Fig. 4a (not shown) an uncut cord winding may be applied before the layer 3d, whilst in a further modification Fig. 4b (not shown) a mouldable rubber layer is inserted between the layer 3d and the leather cover. Specification 498,196 is referred to.
