Title: Fuel supply system for use in aircraft
IPC: B64D37/16
Filed: 1958-06-19
Abstract: 851,428. Fuel supply systems. UNITED AIRCRAFT CORPORATION. June 19, 1958 [Aug. 28, 1957], No. 19622/58. Class 7(3). [Also in Groups XXIX and XXXIII] In an aircraft fuel system described particularly for a helicopter wherein the tank or tanks are located in the lower part of the main freight compartment, a tank 40 is supported by the lower part of the fuselage 10 between bulkheads 50 and 52. The tank is formed with sumps 54 and 56 positioned below the water and sludge level AA and a container 68 is sealed at its base to sump 54, is open at its top and is provided with an aperture 69 above level AA having a one-way valve 73 which permits fuel flow only into the container. An electrically driven booster pump 66 draws fuel from the interior of the container and delivers it through conduit 82, strainer 80 and valve 92 to engine driven pump 88 from whence it is delivered to the engine 25. Sump 56 supports a filter 107 which encloses an ejector pump 98, the outlet 108 connecting by pipe 118 and non-return valve 120 with container 68 and the nozzle 112 being fed with fuel tapped from pipe 96 by pipe 122 either upstream or downstream of pump 88. Drain valves 64, overflow connection 65 and vent 91 are provided. The arrangement ensures that the tank will be completely emptied regardless of the attitude of the aircraft for in a dive with fuel at level B container 68 will be supplied with fuel through valve 73 whereas in a climb with fuel at level C the ejector pump will feed container 68 and pump 66 through pipe 118. In level flight both pumps function. A further embodiment is described of two connected tanks, one as shown in Fig. 2 and the other having an ejector pump only, also feeding into container 68. In this arrangement the ejector pump may be dispensed with in the tank containing pump 66.

Abstract: 1511515 Kinky glass fibres OWENS-CORNING FIBERGLAS CORP 12 May 1975 [13 May 1974] 19932/75 Heading C1M Continuous glass fibres with lengthwise undulations are produced by drawing the glass from a stream feeder, attenuating the stream, directing a stream of fluid against the side of each fibre from a position spaced from the fibre path and in a region where the fibre is still soft, and cooling the fibres to make the resulting undulations permanent. The fluid (e.g. water, dilute acid or alkali, foam, carbonated water, CO 2 , N 2 , or air) is preferably directed near to the tip of the cone of the glass being drawn. The fibres may be vibrated (e.g. by rotating fluted or spirally grooved rollers, by out of phase rotating vanes or by a whirling air stream) at a position where they are substantially solid. The fibres may be drawn from two glasses with different coefficients of expansion whereby kinky fibre formation is enhanced. The stream feeder may be of a Pt-Rh alloy.

Title: Arrangement for separating electric currents of different frequency
IPC: H03H7/01
Filed: 1939-07-13
Abstract: 543,045. Impedance networks. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 13, 1939, No. 20471. Convention date, July 13, 1938. [Class 40 (iii)] A frequency separator comprises two quadripoles having the same real impedance but different phase changing characteristics, the input terminals being connected in series or parallel and the two pairs of output terminals being fed respectively with the sum and difference of the individual outputs from the quadripoles through a hybrid transformer or its equivalent. In Fig. 1, the quadripoles F, F<SP>1</SP> are of lattice type, and their phase-shift angles α,α<SP>1</SP> are such that up to a frequency f<SP>1</SP>, α = α<SP>1</SP> + #, while above a frequency f2 a = α<SP>1</SP>, these relations being approximate. It follows then that the arrangement acts as a low-pass filter between terminals I and II and as a high-pass filter between terminals I and III. The networks F, F<SP>1</SP> may be developed so that over alternate frequency bands α = α<SP>1</SP> + (2k + 1) # and α = α<SP>1</SP> + 2k#, the bands being therefore alternately passed and suppressed at each pair of output terminals II, III. In Fig. 7, the quadripoles take the form of two pairs of inverse reactances X1, X2 and X 1 <SP>1</SP>, X 2 <SP>1</SP> in association with a differential transformer, the two transformers being provided with additional windings to feed the output terminals II, III. In a modification, the quadripoles are connected in series instead of in parallel.

Title: Improvements in refill pencils
IPC: B43K21/16
Filed: 1923-08-13
Abstract: 202,325. Druseidt, P. Aug. 14, 1922, [Convention date]. No Patent granted (Sealing fee not paid). Pencil-holders.-In a pencil-holder of the kind in which a rod is longitudinally slidable in the holder to propel the lead over a predetermined distance, the rod is connected to a cap slidably mounted at the rear end of the holder, and is bent to pass through a slot in the holder for the purpose of limiting the longitudinal movement. As shown in Fig. 1, the end of the rod 3 is bent to pass through a slot 1<a> in the holder 1 into a hollow 4a formed in the cap 4. The rod is also bent to form an abutment 7 which is adapted to be held by the resiliency of the rod in engagement with one of a pair of indentations in the holder, the indentations serving to hold the rod in projected or retracted position. The shape of the indentations is such that greater force is necessary to move the rod backwards than forwards. The extension 2 is adapted to screw into the part 1 to provide for fine adjustment of the lead. In a modification, the end of the rod passes through an aperture in a cap slidable within the end of the holder before entering the slot 1<a>. The Specification as open to inspection under Sect. 91 (3) (a) also describes pencil-holders in which the parts 2, 3, Fig. 1 (Cancelled), are frictionally held against displacement by spring tongues 10 on the part 3. A lead-holding tube 11 is mounted in the part 3 and is formed with a. spring tongue 12 for gripping the lead. The tube is formed from a. strip of material provided with the tongues 12 at the correct distances apart, and, below the tongues, with holes to enable the strip, after having been drawn into tubular form, to be broken into.pieces of the correct length. The propeller-rod 4. which is bent at its rear end 5 to pass through the slot 6 into a groove in the external cap 7, is provided with a springy extension 8 adapted to snap into a recess 2a in the part 2 to hold the lead in the forward position. In a modification, the part 5 passes through an aperture in an internal cap into a slot in the part 2, and the extension 8 is adapted to engage a hole in the casing. In another modification, the part 5 passes through a slot in a tube inserted in the end of the part 2 and engages the interior wall of an external cap, and the part 8 is adapted to spring under the end of the tube. This subjectmatter does not appear in the Specification as accepted.

Abstract: 898,807. Two-part couplings. BURNDY CORPORATION. June 10, 1960 [June 16, 1959], No. 20564/60. Class 38 (1). A pin or, as shown, a socket contact 24 is automatically locked in an aperture 54 in a panel 18, when inserted from the end 56 of the aperture, by spring catches 28 which project through apertures 12 in a sleeve 10 surrounding the socket and engage a shoulder 38 in the aperture when a flange 16 on the sleeve 10 abuts an oppositely facing shoulder 20. To release the socket it is pushed further into the aperture so that the sleeve 10 overrides projections 44 on the socket, which normally prevent accidental release, and cam surfaces 37 on the apertures 12 acting on inclined surfaces 36 of the catches 28 withdraw the latter from engagement with shoulder 38. At the same time latches 29 which extend beyond catches 28 bend upwards and engage apertures 14 in sleeve 10 to hold the catches in their retracted position whilst the contact is slid out of the end 56 of aperture 54. Latches 29 are released before re-insertion of the socket. Said latches and catches 28 are formed on the ends of one pair of four spring fingers slit from the socket wall, the other pair 30 forming wiping contacts.
