Title: Improvements in removable tabs or labels for marking textile articles
Inventor: MEYER HANS
IPC: G09F3/04
Filed: 1952-08-27
Abstract: 735,236. Laundry &c. labels. POLYMARK, Ltd. Aug. 27, 1952, No. 21571/52. Class 142(4). Labels to be applied to a garment by heat and pressure and subsequently peeled off are made from a closely-woven single ply fabric having weft yarns d and warp yarns C of cotton or viscose, which together constitute a coherent fabric, and thermoplastic warp yarns A, which pass over one weft yarn and under two, whereby the fabric has a lower proportion of thermoplastic material on the upper face (which is to receive printed identification markings) than on the lower face (which is to adhere to the garment) ; at half the points, such as X, Y, at which the thermoplastic yarns pass over a weft yarn, they are flanked and obscured by the adjacent warp yarns C, thereby further reducing the proportion. In another embodiment, the thermoplastic yarns pass over one weft yarn and under three, alternate thermoplastic yarns being obscured at all points on the upper face, and the intervening ones not at all. The thermoplastic warp yarns are woven under slightly lower tension than the others ; they may be cellulose acetate or other ester or ether, polyvinyl formal or chloride, polyvinylidene chloride, or polythene, and may be monofils or multifilament yarns. The fabric may be woven wide and cut into strips, or may be woven the width of a label, in which case one edge is without thermoplastic yarns to provide an unadhering tab to facilitate peeling it off the garment. Specifications 561,989, 650,910, and 735,280 are referred to.

Title: Improvements in heat exchange apparatus
IPC: F22G5/10
Filed: 1943-12-24
Abstract: 585,465. Steam superheaters &c. DALIN, D. Dec. 24, 1943, No. 21587. Convention date, Feb. 24. [Classes 64 (i) and 123 (iii)] A heat exchange apparatus has a heat exchange chamber divided into two or more compartments and/or is associated with one or more additional chambers or passages, and the flow of a hea'texchanging fluid through those chambers or passages is controlled or cut off by one or more tubular dampers or shutters each of which consists of two or more sets of tubes of which two are fixed at opposite sides of the space or spaces to be controlled and are capable of being bent in opposite directions to vary the total free area between the tubes available for the passage of fluid. In a heat exchanger apparatus such as a superheater in which a tubular damper or dampers 44, 46 control the flow of heating medium through the space 70, the space is divided by a partition composed of vertical water-tubes into two passages, one of which contains superheater tubes 50 and the other of which contains the tubes of an exchanger for heating another fluid. The tubes 44, 46 which are arranged alternately and are connected at one end to the header 43 and at the other to the steam or water spaces of the drum 45, are bent at the points 44d, 46d to form two halves which for each tube are, except for their end parts, of identical shape and lie side by side. The tubes are anchored at 66, 67 to the brickwork, and are connected to rods 54, 63 which are operated by.a crank device 64 through a rod 57 and cranked levers 55, 59, to bend the tubes 44, 46 in opposite directions as required. If desired, fixed tubes may be interposed between the movable tubes 44, 46. Water may be supplied to the header 43 by a pump 89 drawing from the drum 45. The dampers may be actuated, e.g., by a servo-motor, in response to the temperature of the steam, heating fluid, or feedwater, or other characteristic.

Title: Improvements in railway ballast tamping machines
IPC: E01B27/16
Filed: 1953-08-06
Abstract: 731,580. Railway ballast tamping machines. MATERIEL INDUSTRIEL SOC. ANON. Aug. 6, 1953 [Aug. 7, 1952], No. 21715/53. Class 104 (2). In a railway ballast tamping machine with. tamping tools carried by a frame suspended from a piston which is slidable in a cylinder having a fluid supply pipe leading to a space beneath the piston for raising the frame the descent speed of the frame is regulated by valve means including a single acting valve in the pipe and means for adjusting the throttling effect to reduce the descent speed. The frame 2 carrying the tamping tools 6 is suspended from a rod 10 attached to a piston 11 slidable in a cylinder 12 mounted on a machine frame 1. The frame 2 is raised by passing fluid through a pipe 13 to a cylinder space 12<SP>1</SP> below the piston 11. The speed of descent of the frame 2, which falls under its own weight or is accelerated by passing fluid to a cylinder space 12<SP>11</SP> above the piston 11, is reduced through the operation of a single-acting valve in the pipe 13. The piston 11 on descending compresses the fluid into the space 121 which fluid escapes through the pipe 13 to move a block 14 into contact with an abutment 16, as shown in Fig. 1. With the block 14 in this position fluid can only escape through a small hole 141 in the block 14 and thus the speed of descent of the frame 2 is retarded. The speed of descent can be altered by replacing the block 14 by another having a larger or smaller hole 14<SP>1</SP>. To raise. the frame 2 fluid is passed through the pipe 13 to the chamber 12<SP>1</SP> and in passing moves the block 14 to the left, Fig. 1, and then passes freely through a chamber 151 in the valve. In an alternative arrangement' shown in Fig. 2 the sliding block 14 is replaced by a ball 17 and the amount of fluid passing through the valve as the frame 2 descends is determined by a milled out portion 22<SP>1</SP> of a shaft 22, arranged in a bore 20 and rotatably adjusted by means of a hand wheel 21 held in the adjusted position by a spring pressed ball, Fig. 3 (not shown). The descent of the frame 2 is limited by nuts 43 engaging stops 50 or 51. The stops 50 or 51 are carried by slide blocks 42 and are moved into the operative position by a fluid-actuated piston 53 through rods 52 or by a lever, Fig. 6 (not shown), or any other suitable means. The tamping tools 6 are moved towards and away from each other by screws 9 and are vibrated by an eccentric 3 through links 4.

Patent GB-760175-A (GB)
Title: Magnetic core logical circuits
IPC: G11C11/06
Filed: 1954-07-27
Abstract: 760,175. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 27, 1954 [July 30, 1953], No. 21885/54. Class 40 (4). In a pulse transfer circuit which performs the " exclusive or " logical operation on binary digits, a pair of magnetic cores 1, 2 which have bi-stable magnetization conditions provided by rectangular hysteresis loops are each associated with an input winding 3, 7, a read-out winding 4, 8 and a pair of output windings 5, 6 or 9, 10, the two output windings on each core producing voltages of different magnitudes which act in opposite directions in the external circuit. In the arrangements described the magnetic cores are initially driven to the same remanent state by a read-out pulse common to windings 4 and 8. The magnetic polarity of each core may then be reversed by application of an X or Y pulse to the respective input winding 3 and 7. The operating cycle is then completed by a further read-out pulse restoring the cores. Each time the magnetic state of a core is changed a pulse is induced in the associated windings, the induced voltages in the input and read-out windings being without effect. An effective output from windings 5, 6 or 9, 10 is obtained only if an X pulse or a Y pulse but not both are received during an operating cycle. Assuming that an X pulse changes the polarity of core 1, output voltages will be induced in windings 5 and 6, winding 5 producing the higher voltage as it has a larger number of turns. This voltage will be suppressed in the external circuit by a crystal diode 13, while the lower voltage produced by winding 6 will be neutralized by an opposing bias voltage 15. No current therefore flows through the load 17 common to both the cores, Fig. 2, or through loads 18, 19 individual to the cores, Fig. 3. When the cores are restored by a read-out pulse to their initial condition, the direction of the induced voltages is reversed. The voltage in winding 5, (2 v.), then acts in the conductive direction through 13 and overcomes the bias voltage 15, (v.), to produce an effective output voltage (v.). The opposing voltage from winding 6 has no effect since it is suppressed by a crystal diode 14. A similar result is obtained if a pulse Y only is received during an operating cycle, the higher voltage in this case being produced by winding 10. If both X and Y pulses are received in this period, the induced voltages in output windings 5 and 6 are opposed by voltages in windings 9 and 10 and the resultant voltages are insufficient to overcome the bias. In an alternative arrangement, Fig. 4, the output windings are connected to a common load 17 over transistors 20, 21 which have their emitter electrodes 22, 23'negatively biased by potentials Ey and Ex respectively. One or other of these biases is only overcome and current permitted to flow through 17 if an X or a Y pulse alone is read-out, the presence of both signals yielding a resultant reduced voltage which is insufficient to overcome either potential.
