Abstract: 540,802. Ventilating buildings. FISK, E. T. May 17, 1940, No. 8867. Convention date, June 23, 1939. [Class 137] Ventilation openings 21, 24 are arranged in the opposite walls of a room or building, each opening having a window comprising two or more spaced panels 1, 2, 2A, 3A, top and bottom inner panels 2A, 3A being adjustable vertically to control the opening between them. Air entering the window at one side is heated or cooled by a coiled pipe 17 provided with fins 4 above which are a series of fans 5 driven from a common shaft 6, the motor being reversible. A partition 28 carries a box-like structure between which and the ceiling 23 is a space 32, the air passing through this space and under a baffle 33 into contact with finned pipes by which it is heated or cooled, fans over the pipes ensuring circulation. The air escapes through the window in the opposite wall. The fans are controlled so that the direction of the air current through the room is that of the prevailing wind. A brine pump 7 in conjunction with a refrigeration plant 9, 10 and 11 forces the cooled brine through the finned pipes. When heating is required, the refrigerator is shut down and the brine diverted through a boiler 18.

Abstract: 1,078,777. Equipment for training or testing a swimmer. P. ELIA, K. ELIA and G. N. COVINGTON. Feb. 16, 1966 [March 2, 1965; March 19, 1965; Aug. 26, 1965], Nos. 8888/65; 11817/65 and 36737/65. Headings A6D and A6M. Equipment for training or testing a swimmer comprises a rotatable means, a flexible line extending round said rotatable means, connecting means for attaching the line to a swimmer, whereby, when the swimmer moves away from said rotatable means, the line is taughtened, drawn after him, causing rotation of said rotatable means in one sense and means for applying a resistive load, acting through said line, against movement of the swimmer away from said rotatable means, the arrangement being such that, as a result of return movement of the swimmer towards the said rotatable means, the latter are caused to rotate in the opposite sense and thereby to effect reverse move - ment of the flexible line running round them. One form of the equipment, as shown in Fig. 2, comprises a casing 1 in which is rotatably mounted a drum or wheel 2, on which is coiled a cord or cable 3, of which the free end runs over a pulley 4 and out through an aperture in the casing wall. Rotation of the drum or wheel 2 can be resisted by friction means 5, and an adjustable mechanism 6, with a handwheel 7, for adjusting the friction load. Associated with the mechanism 6 may be means 9 for indicating and/or recording the imposed resistance, a stop-watch 10, and a cyclometer 11 to indicate and/or record the rotations of the drum 2. Other friction means specified include a brake means which comprises a friction wheel secured to the shaft of the rotatable means, a friction band extending round the friction wheel anchored at one end and weighted or sprung at the other end; or adjustable half-bearings in which the shaft of the rotatable means rotates. Alternatively, the resistive force may be transmitted to the rotatable means by a flexible line wound upon a constant diameter helically-grooved sleeve or conical worm, whereby the resistive force is varied as the line winds on, or unwinds from, the conical worm. A modification of the above equipment comprises two rotatable means wherein either an endless loop runs between two spaced drums provided with a means for attachment to an athlete and a braking load is applied to one or to each drum, or the opposite ends of a rope may be wound upon two spaced drums which have braking means and have means for attachment to an athlete; a spring means may be provided to ensure that the drum towards which the athlete is moving rewinds.

Filed: 1940-05-25
Abstract: 538,075. Welding chain links. NORTH BRITISH ELECTRIC WELDING CO., Ltd., and GLOVER, T. S. May 25, 1940, Nos. 9242 and 13043. [Class 83 (iv)] In making studded chain links by automatic electric resistance welding, two complementary half links are welded together and at the same time the stud is seated on both half links and is keyed with portions of at least one of the half links adjoining the welded extremities thereof. The half links are formed with inwardly-facing upset portions presenting a plane surface 1b, 2b parallel to the length of the link. These portions are machined to form small keyways 5 having sloping bases with which engage non- circular projections 4 on the ends of the stud 3, the other portions of the ends of the stud engaging the seats on the half links. One half link projects beyond the minor axis so as to provide excess metal which is sparked off in welding so that the plane of the weld is on the minor axis. In a modification the ends of the stud are formed with unilateral projections 6, Fig. 8, projecting into mating keyways in one only of the half links. In either case the pressure applied during welding forces the inclined bases of the keyways into intimate contact with the projections so that the link is welded and the stud keyed in the same operation. The projections may be formed on the link and the keyways in the ends of the stud.

Abstract: 1365911 Matrix displays UNIVERSAL TELEWRITERS (PTY) Ltd 14 April 1972 [14 April 1971] 9406/71 Heading G5C A display device comprises an opaque apertured sheet 2, a shutter 11, 16, mounted on a magnetic member 21 ... 26, associated each aperture 4, 5, 6 and a plurality of selectively energized magnetic field producing means which move each member and to shutter between two stable positions. Conductor loops 31, 32, 33, 41, 42 extend along each row and column of pivot axes of the magnets. A current pulse in any vertical loop produces a horizontal field which moves adjacent shutters unless they are held down by a vertical field produced by a horizontal loop. Alternatively a combined horizontal and vertical field may be required to move the shutters. The shutter and magnetic member may form a single component. The movement of the shutters is limited by stop members which may be permanent magnets to increase stability. In another embodiment the magnetic member is of soft iron. The two arms of the horizontal loops are in a vertical plane producing a field which magnetises the member which can then be moved by current in vertical loops. Alternatively the shutters are mounted in square apertures and comprise cylindrical members 70 with opaque and transparent areas. The cylinders are pivoted about their axes 72 and the mangetic members 73 are radially mounted. A spherical shutter may be mounted in a circular aperture.

Title: New stilbestrol derivatives and preparation thereof
IPC: C07F9/12
Filed: 1953-04-07
Abstract: Phosphoric acid esters of diethylstilboestrol and water-soluble salts of said esters are obtained by recting diethylstilboestrol with phosphorus oxychloride by heating, preferably to the b.p. of the phosphorus oxychloride, in the presence of an organic base, e.g. pyridine, capable of binding the hydrogen chloride developed during the reaction, the proportion of the base employed being just sufficient to bind the whole of the hydrogen chloride developed, and the phosphoric acid ester formed is separated from the reaction mixture, purified via a readily soluble ether adduct, and if required is converted into a water-soluble salt, for example its sodium salt. To obtain the mono and diphosphoric acid esters 1 and 2 mols. of phosphorus oxychloride per mol. of diethylstilboestrol respectively are employed.  The desired ester in analytically pure form may be obtained from the ether adducts by heating in vacuo.  Salts of the ester, e.g. the sodium salt, are produced by dissolving the ester in sodium hydroxide solution and precipitating the sodium salt from this solution by the addition of an organic liquid, e.g. acetone. Alternatively the salt of the ester may be obtained by treating in absolute ethanol with sodium and isolating the sodium salt thus formed. Specification 539,506 is referred to.

Title: Improvements relating to the adjustment of the cylinders of rolling and milling machines
IPC: B29B7/68
Filed: 1964-03-06
Abstract: 1,063,731. Rolling-machines. A. L. VERDIER. March 6, 1964 [March 19, 1963], No. 9513/64, Heading B5A. [Also in Divisions F2 and G3] A rolling-machine, particularly intended for sheeting pasty materials such as those used in producing printing inks, paints, soap or chocolate, has an hydraulic gauging means for sensing the distances between the end bearings of adjacent rolls, and means for varying the working pressures acting upon the bearings to compensate for variations in these distances, thereby maintaining the roll gap constant. In the embodiment shown, rolls 1-3 are rotated at different speeds, roll 3 fastest and roll 1 slowest, roll 2 is a floating roll, and roll 3 is journalled in pivoted bearings 3A, 3B which are supported by pistons 9B, 8B respectively held in cylinders 9, 8. The cylinder chambers 8D, 9D are fed with oil from a reservoir 12 via pipes 16, 17 and valves 15, 18 and while the machine is at rest the rolls are pressed against one another and the pressures in chambers 8D, 9D are equalized. Also chambers 8C, 9C are fed with oil and are connected by pipes 20, 21 through a differential pressure gauge 19. According to the invention the pressure on the material entrained during rolling is greater, and hence the pass between the rolls is least, at the non-driven side (righthand side of Fig. 2) than at the driven side, so that the gauge 19 indicates a greater decrease in pressure in chamber 8C than in chamber 9C. Equality is restored by reducing pressure in chamber 9D by operation of valve 18, which operation is preferably automatic, such as by means of a servo-motor, and indicated diagrammatically by chain line 26. Differences in pressure along the length of the rolls caused by variations in the rotational speed of the rolls is indicated and may be compensated for in a similar manner. In a second embodiment, electric valves are used, and in addition to valve 15, whose setting determines the pass between the rolls, a valve (33A), Fig. 3 (not shown), slows down the rolls when valve 15 is unable to create the required pressure in chambers 8D and 9D.

Title: Improvements in or relating to sound reproducing machines
IPC: G11B17/02
Filed: 1932-04-02
Abstract: 398,921. Gramophones. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and BOWEN, A., 38, Bull's Head Lane, Stoke, Coventry. April 2, 1932, No. 9516. [Class 40 (ii).] Relates to automatic stop-mechanism for gramophones, in which a member for operating a switch or brake is repeatedly displaced from and returned to an inoperative position while the stylus traverses the record, a rapid inward movement of the stylus at the end of the playing of a record effecting an abnormal displacement of the operating member in such a manner as to actuate the stopping device. According to the invention, the return movements of the operating member are effected by a rotating element, the operating member and the rotating element being so shaped and arranged that after the abnormal displacement of the operating member it is thrown back by the rotating element with such velocity that it is carried by its momentum intoa position where it actuates the switch or brake. In the construction shown, a pivoted arm 6 moving with the pick-up arm 7 frictionally engages with a lever 2 mounted on the same pivot 3, and slowly moves the lever towards the turntable 1. A cam 5 on the turntable has a slightly eccentric edge 5a and a face 5b with a steep slope. Each revolution of the turntable causes the cam edge 5a to push back the lever 2 repeatedly, until a sudden inward movement of the pick-up arm at the end of the record effects an increased inward movement of the lever 2. This enables the cam face 5b to throw back the lever sharply, and since the lever has considerable mass its momentum is then sufficient to allow it to reach a switch member 8 and to open the motor circuit at 9. A lever 10, pivoted at 10a, is engaged by the pick-up arm when this is returned to its outer position, the lever 10 resetting the lever 2 to allow the switch to close. In a modification, a lever corresponding to the lever 2 is bent so as to lie partly below and partly above a switch-supporting plate which is slotted for the passage of the lever and for a pin thereon which actuates the switch. In this case, cam surfaces are provided on the lever instead of on the turntable. The resetting device is also modified.
