Title: Improvements relating to flock-coated webs and to flocks suitable for the manufacture thereof
Inventor: EWING HENRY
IPC: D04H11/00
Filed: 1949-09-07
Abstract: A flock, the fibres of which do not tend to adhere to one another when applied to an adhesive coated fabric in the manufacture of pile fabrics by the electro-coating method, is prepared by coating fine fibres not greater than 5 mm. long of an artificial textile material with a finely-divided, solid, non-thermoplastic, water-insoluble, inert, substantially neutral inorganic substance, the substance being applied to the fibres as an aqueous dispersion in which the major dimension of at least 90 per cent by weight of the particles of the substance is between 1 and 50 microns, the dispersion containing no dispersing agents and the treated fibres being subsequently dried. Alternatively, the dispersion is applied to continuous arti-ficial filaments and after drying the filaments are cut or ground to a fibre length not greater than 5 mm.  Specified inorganic substances are precipitated silica, magnesium oxide, talc, precipitated calcium carbonate, barium sulphate, china clay and aluminium oxide.  The examples describe the manufacture of flocks of cellulose acetate and regenerated cellulose fibres, but the process is also applicable to fibres of cellulose propionate, butyrate, acetate-propionate and acetate-butyrate, ethyl cellulose, benzyl cellulose, polyhexamethylene adipamide, polyethylene terephthalate, polyaminotriazole, polyacrylonitrile, vinyl chloride-vinylidene chloride, vinyl chloride-acrylonitrile, vinylidene chlorideacrylonitrile, acrylonitrile-methacrylonitrile and artificial proteinaceous fibres.

Title: Improvements in rate of turn responsive devices
Inventor: MEREDITH FREDERICK WILLIAM
IPC: G01P3/49
Filed: 1951-10-09
Abstract: 713,550. Electric indicating systems. SMITH & SONS (ENGLAND), Ltd., S. Oct. 1, 1952 [Oct. 9, 1951], No. 23510/51. Class 40 (1). A device for measuring rate of turn comprises a housing 1 in which an inertia member 5 is rotatably mounted at 4. The housing carries an annular laminated magnetic member 8 shaped to form a series of pole pairs along its circumference which are disposed adjacent an annular magnetic strip 7 and an eddy current strip 6 e.g., of copper secured to the inertia member. The member 8 carries two series of coils 13, 14 so disposed on the poles that when the inertia member is stationary relative to the field member 8 there is substantially no coupling between the two coil series. The primary coil series 13 is A.C. energised and an output is derived from the secondary coil series 14 which is zero for the above mentioned stationary relative conditions and varies in phase sense and magnitude according to the relative displacement of the inertia member and the housing. The device will respond to rate of turn or angular acceleration dependent on the inertia of the member 5 compared with the acceleration rate and the time constant of the member is so chosen that it responds only to the rate of turn components involved. A single unlaminated mild steel strip may be used in lieu of strips 6, 7 and the space between the inertia member and housing is filled with a lubricant 15 having a specific gravity substantially equal to that of the inertia member to reduce shock loads upon the bearings of the arbor 4.

An open-ended radio feed horn is provided on its outside wall with a quarter-wave choke (the wavelength being taken at a preselected midband frequency) the forward end of which is rearwardly spaced from the open end of the horn by a distance greater than one-eighth of a wavelength but less than a wavelength. As described, a circular waveguide 10, Figs. 1, 2, has an open radiating mouth 14. A sleeve 16 of larger diameter than the waveguide is backwardly offset from the mouth 14 and is mounted on a support ring 18. The annular region between the sleeve 16 and the outer surface of the waveguide is dimensioned to act as a quarter-wavelength choke at the frequency of operation. An annular reflector plate 22 surrounds the outer surface of the sleeve 16 and is secured by a second support ring 24. The other end of the waveguide 10 is provided with a flange coupling 12. In a second embodiment (Fig. 6, not shown), a circular waveguide terminates in a radiation-transparent window, the edges of which are clamped between a flange formed on the outside of the waveguide, and a clamping ring. A quarter-wave choke sleeve and a reflector plate are provided which are backwardly offset from the radiating mouth of waveguide, and the said reflector plate has additionally a shield or skirt extending forwardly from its edge. In a third embodiment (Fig. 7, not shown) a rectangular waveguide is used. The reflector plate may be rectangular or circular and carries the quarter-wave choke sleeve surrounding the mouth of the waveguide and conforms in shape thereto. A series of forwardly projecting parallel vanes is provided at the edges of the reflector plate which are perpendicular to the electric field orientation of the fundamental mode in the rectangular waveguide, and which extend for substantially a quarterwavelength, so defining a series of chokes. Where the waveguide is to handle crosspolarized signals, the vane structure is extended along all margins of the reflector plate. In a fourth embodiment (Fig. 8, not shown), a flared radiating horn is provided at the open end of the waveguide and is surrounded by a correspondingly flared choke sleeve.

Title: Apparatus for automatically stabilizing a variable parameter of a fluid
IPC: G05D7/06
Filed: 1964-06-08
Abstract: 1,074,542. Telemetering system. G. WEISHEIT. June 8, 1964, No.23591/64. Heading G1N. [Also in Division G3] In an electrical system for automatically stabilizing a fluid variable, there are two signal generators responsive to deviations of the variable, one of which switches the correcting means on and off and the other of which varies the speed of operation of the correcting means in proportion to the deviation. In Fig. 1, a flowmeter 11 measuring rate of flow of liquid in a conduit 10 influences a galvanometer 15 so that if the rate of flow deviates in one sense from a value determined by the setting of a resistance 14, a constant width armature 19 of magnetic material carried by the galvanometer pointer 16 couples opposed coils 23 associated with a transistor circuit 26, 27 supplied with pulsating A. C. from a source 48. As a result, a solenoid 28 is energized to operate a valve 12 against a spring 41 to correct the rate of flow. A variable width armature 20 of magnetic material, also carried by the galvanometer pointer, varies the coupling between opposed coils 24 associated with a transistor circuit 31, 33 energizing a solenoid 35. As a result a restrictor valve 45 associated with a hydraulic damper 36 is adjusted so that the rate of movement of valve 12 increases with the magnitude of deviation. Movement of restrictor valve 45 adjusts a resistance 53 in a bridge circuit 51 associated with a meter 50 to indicate the magnitude of deviation. Operation of a switch 54 to its other position disables automatic control and permits manual control of valve 12 by a potentiometer 55. Operation of a switch 56 to its other position completely closes restrictor valve 45 so as to hold valve 12 in the position it occupies.

Title: Incandescent lamp
IPC: H01K1/18
Filed: 1963-06-13
Abstract: 1,005,127. Tubular incandescent lamps. SYLVANIA ELECTRIC PRODUCTS Inc. June 13, 1963 [June 13, 1962], No. 23654/63. Heading H1F. An incandescent lamp comprises a sealed tubular light transmitting envelope having a coiled-coil filament including at least two separate portions connected together by a wire of larger diameter than that of the filament, each end of the wire fitting into the adjacent end of the seconding coil of each portion and the wire being formed between its ends into a loop fitting against the inner wall of the envelope. The end of each coil not engaging the wire loop is connected to a lead-in wire. To avoid using a wire loop in the middle of the lamp filament, the filament may be made up of two outer coils 9 and a central coil 10, wire loops 11 being fitted between the coil 10 and each coil 9. Preferably the end coils are of slightly larger diameter wire than the middle coil, the internal diameters of all the primary coils being the same. The loops 11 may extend only partially round a circle, e.g. for 300 degrees, the ends being turned in radially to engage the filament coils. For a three filament coil arrangement as shown, two similar coils may be made, the ends of which extend outwards as legs to engage the ends of the wire loop. One of these coils is then cut in half to form the end pieces 9. The cut ends are then connected to the lead-in wires 7 the ends of which are shaped to fit into the ends of the filament. The lead-in wires are connected to pieces 6 of molybdenum ribbon within the flattened ends 3 of the envelope 2. The wire loops may be molybdenum, nickel or tungsten, the latter being used when the lamp filling contains iodine.
