Title: Improvements in the Manufacture of Fringes for Shawls, Rugs and the like.
IPC: D04D5/00
Filed: 1917-08-31
Abstract: 114,572. Buckley, Ltd., W., and Buckley, G. A. Aug. 31, 1917. Rugs, travelling and like.-A cord a is laid sinuously between two pieces of gauze or like thin material b, coated internally with gum, &c., and the whole is pressed between hot rollers to fix the gum, and passed through a sewing-machine to stitch the loops down. The projecting loops are then cut so as to form hanging fringes. A single piece of material, such as b, folded longitudinally, may be used instead of two pieces. The fringe thus made is secured by stitches e within pockets or recesses d in the thickness of the margins of a rug &c. c, as described in Specification 5560/14. In a modification, the fringe is formed directly between the open margins of the rug &c. without employing a strip or strips such as b
Patent GB-720956-A (GB)
Title: Improvements in or relating to centrifugal fan wheels
IPC: F04D29/30
Filed: 1953-05-06
Abstract: 720,956. Centrifugal fans. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 6, 1953 [June 21, 1952], No. 12570/53. Class 110 (1). In a centrifugal fan impeller comprising aerofoil blades attached at their ends to a back plate and a shroud plate, the blades comprise light-weight sponge-like (i.e. having a large number of interstices with air cells therein) cores within and adhesively bonded to outer skins of sheet metal, preferably aluminium. The impeller may be of the double-inlet type, in which case the back plate is the centre plate of the impeller. The core may be of a plastic composition which is poured into the blade through a hole in the back plate or shroud plate and is subsequently heated to cause it to foam and thus expand to press against and adhere to the inner surface of the blade skin. The plastic composition may be a mixture, such as tolylene diisocyanate plus alkyd resin, which generates its own heat. Alternatively, the heat may be applied externally, in which case the core may comprise pellets of nylon and phenolic rubber, or granular cork mixed with phenolic varnish. As a further alternative, the core is preformed, coated with an adhesive, and slid into an open end of a preformed blade. Or, the blade skin is wrapped around the preformed core with adhesive between them, the trailing edges of the blade skin being secured together in a lock seam. A suitable material for a preformed core is a foamed styrene. Or, a cellular or honeycomb texture may be provided by the use of resin impregnated paper or cloth, aluminium foil or cellular cellulose acetate. Holes 25, Fig. 9, can be pressed inwardly to assist in bonding the core 24 to the skin 23. The core may have a void within it, as shown in Figs. 4 and 8, where a hollow inner skin 26 of aerofoil shape is provided. In the modification shown in Fig. 13, a cellular core 38 is folded over an inner member 37 and then the outer skin 23 is folded around the core, and the trailing edges of the outer skin are joined together by a lock seam. Granular composition 39 is then poured into the vacant space at the trailing end, and heated. Alternatively, the voids may be formed by one or more hollow tubes 27, Fig. 11, passing longitudinally through the core. By expanding the ends of the tubes as shown, the blades are secured in place between the back plate 21 and shroud plate 20. In addition, the blade skin may be welded at 35 to the plates. Figs. 8, 9 and 10 show alternative ways of attaching the blades to the plates. Rivets are shown, but welding may be used instead at the connection to the blade skin. In Fig. 8, angle bars 30, 31 extend around the outside of the blade; and in Fig. 9, channel members 32, 33 are used. In Fig. 10, the use of W-shaped attachment members 34 avoids the use of blind riveting at the connection to the blade skin. Specification 488,781 is referred to.

Abstract: 1,208,393. Variable capacitors; vacuum switches. INTERNATIONAL STANDARD ELECTRIC CORP. 12 March, 1969 [20 March, 1968], No. 13029/69. Headings H1M and H1N. In a motor driven vacuum variable capacitor or vacuum switch, the hermetically sealed envelope containing the device is divided by a partition into two hermetically sealed compartments one of which contains the electrodes or switch contacts and is at a pressure lower than that in the second compartment containing the reversing motor, driving member, and means interposed between the driving member and mobile electrode or switch contact to effect movement thereof. In the variable capacitor shown, the partition comprises bellows member 60 which divides the envelope into compartments 10, 12 and allows movement of capacitor plates 64. The pressure differential across the bellows is less than in conventional capacitors, reducing stress on the bellows, and conventional lubricants may be used in the motor compartment since this is not under high vacuum.

Title: Improvements in or relating to very high frequency phase comparators
Inventor: TYLER VICTOR JOSEPH
IPC: G01R25/00
Filed: 1954-05-05
Abstract: 771,684. Phase discriminators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 15, 1955 [May 5, 1954], No. 13129/54. Class 40(5) The magnitude and sense of phase difference between two high frequency currents or potentials are measured by applying currents proportional to the currents or potentials in push-pull to diagonally opposite conductors of an array of four parallel conductors 1, 2, 3, 4 arranged in square form and deriving sum and difference votages from parallel conductors 11, 13 and 12, 14 respectively, intersecting the mid-points of the sides of the square. Rectifiers 18 at the unearthed ends of conductors 11, 12, 13, 14 then act as a full-wave commutiting arrangement for measuring the A.C. voltage (proportional to small phase differences) between the ends 14B 12B, the arrangement being switched by the sum voltages arising at the ends 11B, 13B and the A.C. voltage across 12B, 14B in sign and magnitude, being measured by a centre-zero meter 17 connected to the ends of the conductors 11, 13 opposite to the ends 11B, 13B. A capacitor 19 between the ends 14B, 12B tunes the conductors 14, 12 to resonance so that the A.C. voltage across 14B, 12B is rotated through 90 degrees relative to the voltage induced on conductors .14, 12 and is in phase or anti-phase with the switching voltage across 11B, 13B depending on the sense of phase difference. Further, even if the currents on the conductor pairs 1, 3 and 2. 4 differ slightly in magnitude, being OA, OB (Fig. 6) giving OC as the vector sum and AB as the vector difference having components AE. EB, then EB is measured by the above arrangement and is proportional to small phase differences. The conductors 1-4 may be connected to low impedance current responsive probes 10, 7 placed adjacent the currents to be compared in phase, by resonant lines of length n#/2 where n is an integer and x the effective wavelength is the line and capacitors 5, 8 series tuning the lines 1-4 to resonance. Alternatively, if a voltage phase is to be measured the line is.made of length n#/4 where n is an odd integer, and is connected through high reactance capacitors to points of the voltage source and equal and opposite potentials, the mid-point being earthed. Balancing arrangements may be used where the line is of coaxial type. In a modification the meter is connected to the ends 14A, 12A of the conductor pair 14, 12 (RF earthing condensers being inserted the ends 14A, 12A and earth) and the rectifiers 18 are arranged all to conduct simultaneously when 13B is positive relative to 11B, i.e. a half-wave synchronous gating arrangement is used for measuring the A.C. voltage across 14B, 12B. The secondary conductors 11, 13 and 12, 14 may alternatively be at the corners of any size of square at 45 degrees to the primary square of conductors 1-4. The system may be applied to power meters and reflectometers.
