Title: Supported vessel and means for support thereof
IPC: E04H7/02
Filed: 1975-11-06
Abstract: 1504546 Supporting vessels TIOXIDE GROUP Ltd 23 Sept 1976 [6 Nov 1975] 46093/75 Heading BIX A vessel such as a reaction vessel is supported to allow for movement due to thermal and pressure variations by means of webs 1 attached at their outer ends to projections 3 on the vessel walls and at their inner ends or centre to support posts 2 secured to the ground. The projections 3 may be integral with the webs. In a modification the posts are replaced by a unified structure comprising posts linked by cross-bracing which carries supports for the webs, said supports comprising a pair of compliant, vertical, spaced apart plates to which the webs are attached.

Abstract: 1416154 Electron beam systems; electron multipliers; photo-electric detectors POST OFFICE 24 Sept 1973 [6 Oct 1972] 46131/72 Heading H1D A device, for use in an opto-electric transducer, comprises a length of monomode dielectric optical waveguide having a core and a cladding, said length of waveguide being tapered along a section forming at least part of its length so that light propagating along the length will interact with a photocathode formed on a circumferential surface of the length of waveguide. Fig. 1 includes core 1, cladding 2, infra-red sensitive photoemitter 9 on taper 6 within anode 4 and B field 3 from coil 15 (Fig. 3, not shown) assisting coupling with channel multiplier 8. Light entering taper 6 increasingly propagates through the cladding and the structure increases the low quantum efficiency of the infra-red input (e.g. from a GaAs laser). The high E field due to the small diameter of the p/cathode assists electron ejection. The B field may be absent (Fig. 2, not shown), the electrons no longer orbitting spirally; anode 4 may be dispensed with (Fig. 4, not shown), taper 6 projecting into multiplier 8. Visible and U.V. inputs are also instanced and dimensions given.

Title: Method and apparatus for coiling continuous filament yarn
IPC: D02G1/12
Filed: 1962-12-07
Abstract: 1,016,139. Coiling yarn. TURBO MACHINE CO. Dec. 7, 1962 [Jan. 4, 1962; May 21,1962], No. 46221/62. Headings D1F and D1T. In apparatus for continuously deforming multi- or mono-filament yarn by projecting the yarn through the nip of two feed rolls into a space bounded solely by two plane opposed guide surfaces and against a mass of coiled yarn held frictionally between the surfaces, at least one of the rolls has a diameter of between <SP>1</SP>/l6 in. and “ in, and the guide surfaces are spaced from one another by a distance not more than about the radius of the rolls, or of the roll having the smaller diameter. It is stated that the small roll diameter and thus the relatively large distance between the surfaces of the rolls at a fixed point downstream of the roll nip allows the yarn to be formed into helical coils rather than into saw toothed crimps when it meets the accumulated mass of crimped yarn. In the embodiment of Fig. 2 yarn Y passes through tensioning device D, and ceramic guide pins 30, 31 or other guide means to ensure that the yarn reaches rolls 1, 2 at the same axial point. The coiled yarn is passed to a container preparatory to further treatment including either batch or continuous heat setting treatment followed by a tensioning operation adapted to repeatingly extend and relax the filaments so that the coils of one filament become out of phase with respect to the other filaments. The shaft 3 of the roll 1 is mounted in bearings in a leaf 6 swingable on a shaft 7 and adjustably spring pressed against the main housing 8 by a spring 26 on a screw 24. The restrictor guides 40, 41 are yieldingly supported on leaft springs 42, 43 controlled by screws 44, and 45 so that knife edges 46, 47 engage the rolls. Leaf spring 42 is mounted on a segmental plate 33 angularly adjustable with respect to roll 2 so that the distance between guides 40, 41 can be adjusted. In the embodiment of Fig. 9 there are several coiling devices mounted side by side, Fig. 6 (not shown) and having common feed rolls 101, 102. The yarns pass over plates 153, Fig. 6, heated by infra red lamps or other means to the curling clips 120. The coiled yarn then passes between endless belts 200, 201, Fig; 8 (not shown), mounted on rollers which are adjustably mounted to vary the pressure on the yarn, and from thence to a receptacle or heating chamber. Each clip 120 is mounted on a shouldered rod 127 and has spring pressed bars 123, 124 flucrumed at 129. The rolls 101, 102 are rotated by a plurality of partly intermeshing discs mounted on rolls 162-165, Fig. 12 (not shown), in a housing 110. Antifriction bearings of one roll 165 are mounted in movable supports which are adjustably spring urged so that the pressure on the rolls 101, 102 can be varied and so that by means of a lever the roll 165 can be lowered to remove rolls 101, 102.

Title: Telephone looptest system fitting for a high-pressure hose
IPC: H04M3/26
Filed: 1973-10-08
Abstract: 1420658 Automatic exchange systems MAGNETIC CONTROLS CO 8 Oct 1973 [12 Jan 1973] 46855/73 Heading H4K In a system for testing a subscribers line, the line is terminated at the substation end by an interface which selectively connects the line to the subset or to a test impedance under control of an A.C. signal transmitted from the exchange. It is thus ensured that irrespective of the condition of the substation, e.g. grounded, open or short circuit connections, the line itself can be remotely tested by the exchange. The interface 20 contains a balanced transformer I1, I2, I3 connected in series with the line wires and a capacitor C1 shunted across the wires for ensuring continuity for a test signal. The transformer output is applied to an amplifier 28 tuned to the 2800 Hz test frequency and thence a rectifier 30 which guards against transients at the test frequency. The rectifier output is used to enable a relay 36 that transfers the incoming line from the subset 14 to the test impedance 22 for a time governed by times 40. The latter includes a 600 Hz generator whose output indicates to a test equipment 44 at the exchange that the line has been correctly terminated for testing. The capacitor Cl may form part of a series resonant LC circuit which provides greater assurance of line continuity for the test signal. In an alternative arrangement the interface 20 is coupled to the line wires via capacitors, a pair of inductors on the substation side of this coupling ensuring isolation from the substation (Fig. 2, not shown).

Abstract: 1283547 Diaphragm pumps SOC FRANCOHISPANO-AMERICAINE FRANCISPAM 26 Sept 1969 [30 Sept 1968] 47451/69 Heading F1A A pump for filling gas lighters with liquefied gas comprises a bottle 1 for the liquefied gas and a chamber 8 which is filled from the bottle 1 through a valve 14, the chamber 8 being reduced in volume to expel the liquefied gas therein through a bore 17 in a spigot 6 by upwardly moving a diaphragm 3. Interchangeable connectors 22 for fitting a range of lighters are stored within a transparent cover fitted to the bottle 1 to protect the spigot 6, Figs.4-6 (not shown). In use a connector 22 is fitted to the spigot 6, whereafter its fingered end 25 is forced into the lighter's valved filling opening. This movement first raises the spigot 6 to communicate the chamber 8 with the bore 17 via a cross-bore 18 and then the diaphragm 3 moves to expel the chamber's contents. A safety valve 21 is provided. Two further embodiments are described, Figs.2 and 3 (not shown) in which the inlet valve 14 is replaced by a type mechanically closed during the pumping stroke.

Abstract: 1,270,116. Transistor switching circuits. GENERAL ELECTRIC CO. Ltd. 18 Sept., 1970 [30 Sept., 1969], No. 48035/69. Heading H3T. An inductive load, e.g. a transformer primary winding 6, is switched by a transistor which is protected against high back e.m.f. at switch-off by a network connected across the load, comprising a diode 12 and a winding 11 which is inductively coupled to the load, the diode being poled to conduct only at switch-off and the winding being arranged so that the voltage produced by current flow in it is in a direction to reduce the flow. It is explained that with this arrangement the value of a resistor 5, which determines the recovery time of the circuit, may be reduced compared with that which would produce the same recovery time without the additional winding 11. The winding 11 has fewer turns than 6. An external load 9 may be largely resistive. Switching is effected by two transistors 1, 2 in response to pulses from an unspecified source 8.
