Title: An improved inductance and electrical coil
IPC: H01F17/02
Filed: 1924-12-13
Abstract: 248,849. Turner, L. C. Dec. 13, 1924. Inductances.-In air-spaced electric coils, the conductor is wound to cross the coil from the inner to the other edge, or from one side to the other, and vice versa repeatedly, each crossing being displaced about a winding support between the edges or sides of the coil to form an obtuse angle across the coil and successive turns being air-spaced by relative displacement around the coil. The coil may be wound as shown in Fig. 1 about three concentric circles a - - c of parallel pins, the intermediate pins b being radially aligned with the outer pins a or, as shown, with the inner pins c. After the completion of one turn as shown, the winding is continued to form similar, displaced, air-spaced turns, the air spaces on the outer part of the finished coil being of different shape from those on the inner part and bunching of the turns at crossing points being avoided. In a modification, Fig. 4, the conductor is wound about a cylindrical formed with three circles a, b, c of radial pins, the crossings from one side to the other being displaced about the pins b into obtuse angular formation as shown to produce air spaces of different shapes at opposite sides of the pins b and the pins b being aligned with the pins c and opposite the spaces between the pins a. Adjacent turns may be insulated by the cotton covering on the wire or by strips of non-conducting material. Flexible non-conducting material may be looped and tied about crossing points of the winding to maintain the angular formation. The winding pins are round or oval to round the wire passing around them. The Provisional Specification refers to windings about two rows of pins and to square, oblong, semicircular, and oval coils.

Title: Improvements in or relating to methods for measuring electric potentials
IPC: G01B7/16
Filed: 1955-10-20
Abstract: 789,567. Voltage measurement. GUSTAFSSON, G. V. A., and OLSSON, C. O. Oct. 20, 1955 [Oct. 22, 1954], No. 30064/55. Class 37. [Also in Group XXXVIII] In apparatus for measuring instantaneous values of electric voltages, the unknown is switchably applied, for a period of time which is variable as to its duration and instant of commencement, to an indicating instrument (e.g. a cathode-ray oscilloscope) which remains shortcircuited until immediately before the commencement of the time period and is again short-circuited at its termination, and during the period the instrument indicates a comparison between a direct voltage of opposite polarity and variable magnitude and the unknown; the latter being determined with reference to the change of the direct voltage necessary for equality of comparison. In Fig. 4 a resistance strain gauge R1 is connected in a normally balanced Wheatstone bridge 1 energized from a direct voltage source at diagonal A, B to derive a variable voltage signal at diagonal C, D representing stress variations of a specimen on which is superimposed a variable direct voltage signal from potentiometer 12. The combined signal is applied over decoupling resistances to amplifier 3 and the vertical deflection plates of a cathoderay oscillograph 4, whose horizontal plates are energized from timebase 11 synchronized by impulses from trigger circuit 7 tripped by the amplified bridge unbalance signal on each passage of the latter through its arithmetical mean value. Variable delay circuits 8, 9 impulsed by the trigger circuit respectively operate and release relay 10 closing a shorting contact 5 across the oscillograph vertical plates for a time interval of variable incidence and duration adjustable for display of a narrow pulse (Fig. 1) at any point of the cycle of variation of the unbalance signal. The voltage of potentiometer 12 adjusted for coincidence of the baseline and the apex of the pulse (Fig. 2) determines the instantaneous stress signal value at the selected point, and switch 5 may alternatively be operated from the cycles of a fatigue testing machine or in dependence on extensions of a test specimen. The apparatus is also applicable to resistance thermometry. The bridge may comprise inductive or capacitative variable elements with A.C. energization and phase rectification of the unbalance signal.

Abstract: 767,234. Laminated materials. JAUSLIN, A. Oct. 19, 1954, No. 30087/54. Class 140. A laminated material suitable for covering floors consists of a number of strips of worn pneumatic tyres vulcanized side-byside on to a flexible backing. A tyre, Fig. 1, is first treated mechanically to remove the tread 2, and cut into two on a circumferential line C-C. The two portions are mounted on a rotary mandrel back-to-back so that their exterior side walls contact, and on rotation, the inside rubber layer 6 is removed, and the carcass is roughened, by stationary steel brushes. The inside faces are secured together by neoprene adhesive to form an annular disc, Fig. 3, the wires 3 having previously been removed. Further pairs of half-tyres may be secured to the annular disc with the inside faces turned inwards. The disc is cut in a spiral line to produce a long strip of rectangular cross-section and of width equal to the thickness of the disc. The edges of the strip are abraded or cut to a trapezoidal section, and the sloping edges and narrower parallel face are coated with a neoprene adhesive solution. A number of the trapezoidal strips 7, Fig. 4, may be assembled by hand on a backing 8, e.g. of rubber, and a binding paste is squirted, e.g. by means of a grease gun, to fill the grooves 9 between the strips. Alternatively, strips 7 assembled on a table 10, Fig. 5, with the smaller width turned upwards, are advanced between driven feeding rolls 11 and pass over a table 12 having at one side a fixed guide 13 and at the other side a vertical roller 14 where they are urged to contact one another at their longitudinal lower edges. The upper and side surfaces of the strips are adhesivecoated by a device 16, and an open-meshed linen or jute fabric 18, which may carry a dried coating of adhesive, is pressed on to the strips by a roller 17 and becomes bonded to the strips on heating in an infra-red drying apparatus 20. A paste 22 containing rubber and fibre particles obtained when abrading the sides of the strips 7, and also when abrading the surface of the final product at 26 to produce a napped surface, is applied from a hopper 21, and is pressed through the open-meshed fabric into the grooves between the strips by means of pressure rolls 23, a part of the rubber-fibre paste being left above the fabric to embed it. The product is vulcanized. in an infra-red oven 24 and napped at 26. The napped surface may be dyed.
