Patent GB-565097-A (GB)
Title: An improved blood pressure measuring apparatus
IPC: A61B5/023
Filed: 1943-03-01
Abstract: <PICT:0565097/IV/1> In a sphygmomanometer apparatus, the mercury container 2 and the mercury-containing tube 5 are formed as an integral unit of a transparent synthetic resin, e.g. methyl methacrylate or other transparent substantially unbreakable mouldable material.  The bore 6 of the tube 5 is formed as a slit to present a wide ribbon-like column of mercury to assist reading by the operator. The tube 5, which is calibrative in millimetres, is closed by an apertured plug 9 to prevent spilling of mercury, but allowing admission of air.  The container 2 carries a valve 11 to which is attached the usual rubber tube and bulb by which air pressure is applied to the mercury in the container 2 which is closed at the bottom by a plate 4, of the same material as the container, adhesively secured in position.  Screw holes may be provided near the top of the tube 5 for the attachment of the apparatus to a support. The Provisional Specification describes also the embodiment of a spring-loaded piston in the mercury container whereby the mercury may be raised to the equivalence of a minimum of, say, 80 millimeters pressure so to avoid unnecessary scale readings.

Abstract: 469,951. Polishing glass. PILKINGTON BROS., Ltd., and GRIFFIN, J. H. Feb. 5, 1936, No. 3468. [Class 60] In apparatus for polishing flat glass on both sides or surfaces simultaneously, the tools are arranged so that one set operates on one side, and the other set on the other side of another portion of the glass strip, means being provided opposite each set for supporting the strip against the pressure of the tools in that set. The strip 1, driven by rollers 3, is ground by grinding tools 2 opposite each other, and after leaving the tools 2 is washed, to remove sand, and passes over polishing tools 5, and then under tools 7. Whilst over the tools 5, the strip is supported by a roller bed 4, and, whilst under the tools 7, by a roller bed 6 ; the rollers may be idle or may be driven, and a driven belt may pass between the roller beds and the strip, in which case the rollers 3 are omitted. In a modification, Fig. 2, the strip is supported over the tools 5 by tables 8 moved along a guide 9 by rack gearing 12, 13, each table, as it emerges from the guide, passing on to an elevator 15 whereby it is placed on a runway 16 and moved to the elevator 17 which lowers it on to the strip, where it is pushed forward, by a hydraulic pusher 19, again to move along the guide 9; similar tables are used for supporting the strip whilst being polished on the upper surface. The tables may be linked together to form an endless chain, being supported by guides or rollers when supporting the strip.

Title: Improvements relating to pí¬n junction semi-conductor devices and to methods and apparatus for their manufacture
Inventor: GASSON DENYS BROMLEY
IPC: C30B13/06
Filed: 1956-02-09
Abstract: In a method of making a PN junction device (see Group XXXVI) a molten peripheral zone is produced at one end of a cylindrical semiconductor crystal and then moved axially along its length. In the embodiment a crystal 1 of silicon or germanium is mounted with its axis vertical in vacuum chamber 8 within R.F. heating coil and concentrator 3, 4. Graphite <PICT:0843266/III/1> shield 5 is lowered to a position adjacent the concentrator where it becomes incandescent, thereby heating the crystal to a temperature at which it couples directly to the R.F. field. Induction heating then causes a narrow annular zone of the crystal to melt.  An impurity material is added to the melt and the crystal slowly raised to cause the molten zone to traverse it p  axially.  Specifications 727,900 and 728,129 are referred to.

Abstract: 192,927. Jury, A. E. Feb. 11, 1922. Materials, special, ropes and cords of.-Cords or yarns forming the strain-resisting elements of rubber vulcanized articles, such as tyres, are formed from rovings and like fibrous strands without any substantial attentuation, and preferably by loosely twisting them together. Compound cord formed of a loosely twisted yarn combined with one or more twisted strands or yarns may be used. It is stated that in tyres so formed the liability to heating is lessened. Four rovings drawn to a thickness of 1/16 to # i inch may be combined and twisted together, eight twists to the linear inch, forming a soft pliable cord or warp yarn. Such cords or warp yarns may be used as the warp thread of a cord fabric and built into rubber articles before curing; or they may be first woven into fabric.

Title: Signal translating device

Abstract: 927,015. Magnetostrictive non-contact-making relays. STANDARD TELEPHONES & CABLES Ltd. (International Telephone & Telegraph Corporation). Feb. 3, 1961, No. 4169/61. Addition to 914,697. Class 40 (9). By propagating a mechanical pulse along a magnetostrictive element 2, Fig. 2, a signal circuit 1, Fig. 1, is sequentially coupled to a number of separate signal channels 101-150 in turn for the purpose of receiving or transmitting alternating or pulsating signals, the signal circuit being coupled magnetically to the magnetostrictive element by a signal coil 8 and yoke 7, and the mechanical pulse according to its position at any instant effecting a flux coupling between the magnetostrictive element and an adjacent magnetic member 201-250 carrying a channel coil 301-350. The magnetostrictive element is formed of annealed nickel and is supported by rubber units 6 which prevent pulse reflection. Steel wool 17, 17<SP>1</SP> is packed between the yoke extremities and the magnetostrictive element to reduce the reluctance. An electrical pulse is applied over a lead 32 to a coil 3 to produce a mechanical pulse; alternatively a piezo-electric transducer may be used. As the mechanical pulse travels along the magnetostrictive element, transmitter 12 or receiver 13 is activated by a control signal generator 5. Since the mechanical pulse R, Fig. 3, has the property of increasing the reluctance of the magnetostrictive element over the region where the pulse exists, the flux 20 produced in the yoke 7 and the element 2 by the transmitted signal is diverted, as shown, into each magnetic element 201-250 in turn to produce sequential outputs in coils 301-350. Likewise, with the receiver 13 operative, signals in the channels are coupled in turn to the signal coil 8. An alternative construction is shown in Fig. 6 in which the magnetostrictive element comprises a hollow tube 2a surrounding a core 7a on which the signal coil 8a is wound. The magnetic circuit is completed by steel wool 17a, and each magnetic member, such as 201a, carrying a channel coil 301a is magnetically shielded from the coil 8a by the magnetostrictive tube. A modification is shown in Fig. 7, in which the channel coils are carried by magnetic members 201a, 201b mounted within a hollow core 7b. An alternative construction is also mentioned, Fig. 8, in which magnetic members 201-250 and 201c-250c are positioned in pairs on opposite sides of the magnetostrictive element 2, to provide sequential couplings between pairs of elements in turn as the pulse proceeds along the element.
