Title: Improvements in or relating to gas turbine engine fuel systems
Inventor: TAYLOR DEREK
IPC: F02K3/00
Filed: 1954-12-03
Abstract: 791,621. Supplying liquid fuel to burners. ROLLS-ROYCE, Ltd. Dec. 1, 1955 [Dec. 3, 1954], No. 35142/54. Addition to 694,322. Class 75(1) [Also in Groups XXVI and XXIX] The pressure sensitive device described with reference to Fig. 2 of the parent Specification which is used to control the throttle of an air turbine driving a fuel pump supplying fuel to a reheat combustion stage before a propelling nozzle so as to maintain a preselected value of the ratio of a pressure at a point in the engine between the compressor delivery and the turbine inlet to a pressure at a point in the engine between the turbine and the propelling nozzle has the chamber 77 placed into direct communication with the point in the engine between the turbine and propelling nozzle during the initiation of the reheat combustion. A by-pass 105 around the restrictor 79 is controlled by a valve 106 operated by a solenoid 107. Opening of the valve 106 increases the load on the diaphragm assembly 72, 73 in the sense of opening of the throttle 50. To improve the control of the piston 51 by the valve 66 a second restrictor 101 is placed at the entrance to the space 53. This limits the flow into or out of the space 53 and so limits the rate of travel of the piston 51. This restrictor also modifies the effects of pressure changes in the space 53 due to transient conditions on the diaphragm and capsule assembly 70, 72, 73. To initiate reheat combustion the solenoid 63 is energized and valve 62 thereby closed. The pressure in duct 58 then rises and opens the valve 50 by acting on piston 51. To ensure rapid opening of the valve 50 on initiation of combustion, the solenoid 104 is energized and valve 103 opened. The restrictor 101 is then by-passed. The solenoids 63, 104, 107 may be energized simultaneously to start the reheat combustion but after initiation of combustion only the solenoids 104, 107 are de-energized. A conduit 108 with a restriction 109 is provided to drain water from the conduit 80.

Filed: 1960-10-14
Abstract: 939,070. Knitting. S. A. MONK (SUTTON IN ASHFIELD) Ltd., and S. A. MONK. Jan. 15, 1962 [Oct. 14, 1960], No. 35196/60. Class 74 (2). A straight bar rib knitting machine has frame needles I and machine needles 2, alternate frame needles being provided with a picot point 2, patterning elements 5 being also provided for each or every alternate machine needle. The picot points are lowered so that loops are cast off alternate frame needles to produce two and one rib fabric. After a predetermined number of courses the points are withdrawn and knitting continues, to produce a one and one rib fabric. Alternatively, when the latter fabric is produced first and then followed by the former fabric the picot points transfer loops from alternate frame needles to adjacent frame needles, to prevent a run back, the points then being utilised as before to mask the needles and cast off loops. The patterning elements 5 are movable between the position shown to a vertical position and move with and transversely to the needles 4 to transfer loops from those needles to the frame needles (Figs. 6-13, not shown). Pattern effects are produced (Fig. 14, not shown), by using the patterning elements to transfer loops from machine needles to adjacent machine needles first in one direction and then in the other.

Title: Improvements relating to automatic weighing machines
IPC: G01G13/00
Filed: 1929-11-19
Abstract: 342,413. Automatic - feed weighers. SIMON, Ltd., H. and BRIAN, J. C., 20, Mount Street, Manchester. Nov. 19, 1929. No. 35321. [Class 143.] In an automatic weighing machine the material, for example coal, is delivered to the weighing receptacle by movable pockets constituted by division pieces extending across the face of a stationary drum and connected to side plates or discs to which a rotary movement is imparted. The movement of the division pieces causes the material in the pockets to maintain the drum surface in a clean condition. Coal delivered through a shoot a passes over a grid b, the smaller pieces falling through and accumulating in a hopper c whilst the larger pieces lie upon the surface of a stationary drum g and between radial blades e secured to side discs f driven by means of ratchet wheels p, pawls q, connecting rods p<1>, shaft u, gear wheels v, w, and a motor-driven shaft x. To commence an operation a handle 6 is moved thereby engaging, a clutch z and at the same time releasing a brake. The motor drives the shaft u, and the pawls q rotate the blades e so as to carry the lumps of coal forward and dump them down a shoot i into a sack m supported by the weighbeam k. The movement of the coal over the stationary drum g maintains the surface of the drum in a clean condition. A counterweighted lever 32 engaging the underside of a pin 34 prevents depression of the weighbeam during the dumping of the coal. After the blades e have been rotated a predetermined amount, governed by a hand-set guard plate 43, a projection on the wheel v disengages the clutch z and stops the feeding action of the blades, and a cam 22 operating through levers 23, 26 opens the drible feed gate o which is then retained by a catch 38. In moving to the open position a stop piece 31 on the gate removes the supporting lever 32 clear of the weighbeam. The small coal now passes into the sack until the weight is made up when a projection 41 on the beam engages a lever 40 and releases the catch 38. The feed gate then closes under the influence'of a weight 30. When it is desired to weigh small coal only, without utilizing the power-driven mechanism, the feed gate o is opened by hand. In a modification, the weighbeam supports a tipping weigh bucket instead of a sack ring.

Abstract: 1536547 Aircraft guidance system FERRANTI Ltd 10 Aug 1976 [27 Aug 1975] 35437/75 Heading H4D A system for enabling aircraft to keep station when flying in formation involves transmitting from a master aircraft an optical (e.g. infra-red) beam which is narrow in azimuth, scanned in azimuth, and modulated to indicate the azimuth bearing of the beam at any instant relative to the forward direction of the aircraft. This beam is received on a slave aircraft by two or more spaced sensors. Provided that the two aircraft are on the same heading, the time interval between the instants when the sensors intercept the scanned beam is a measure of the distance between the aircraft. A computer on the slave aircraft determines this distance from the time interval and from the demodulated bearing data. Amplitude and pulse width modulation of the beam enable master aircraft identity and heading data to be transmitted in addition to the beam bearing.
