IPC: B60L5/08
Filed: 1951-04-19
Abstract: 697,754. Current collectors. ANTI-ATTRITION METAL CO., Ltd., and LIVINGSTONE, R. Feb. 11, 1952. [April 19, 1951] No. 9202/51. Class 104 (iii). An insert-holder for current collector of vehicles has a spring clamping plate to apply a uniform pressure to the face of the insert, such plate being fastened at one end to the holder so that it cannot twist and at this end is clear of the insert the other end being drawn by a screw or bolt into contact with the insert. A renewable carbon insert 2 is held in position in a holder 1 by a clamping plate 3 attached thereto by screws 4, 5, Fig. 4. The plate 3 is reduced in thickness over the length A so as to be clear of the insert 2 and the remainder of the plate 3 is of sufficient thickness to bear against the insert 2 when the screw 5 is tightened. The holder 1, insert 2 and plate 3 are fastened to a table 6 by a screw 9 and a dovetail 12. The insert pocket in the holder is made with a small radius r at one end, to accommodate the end 2a of the insert 2 of a corresponding radius, and a large radius R at the other end both radii being struck from a common centre O so that the insert can be removed from the holder 1 when swung downwardly about the common centre. The plate 3 may be dowelled, as at 13, Fig. 1, brazed, or soldered along its top edge to the holder 1 to prevent twisting. To ensure uniform lateral pressure on the insert 2 the plate 3 may be provided with a plain semi-circular blind groove at the centre of its top edge combining to form a single circular hole with a similar semi-circular threaded groove in the holder 1, a grub screw being inserted in the hole so that on tightening it applies pressure to the top edge of the plate 3. Alternatively, lateral pressure may be applied to the centre of the plate 3 by a flat or other suitably shaped spring held in a slot formed in the top edge of the plate 3 and engaging a corresponding slot displaced towards the insert 2 in the holder 1, or by a spring and ball or plunger contained in a hole in the plate 3 and engaging an inwardly inclined surface on the holder 1 or by a flat spring fastened in a recess formed on the outside of the plate 3 and engaging a slot in the holder 1.

IPC: F23R3/02
Filed: 1956-03-26
Abstract: 853,108. Liquid fuel burners. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. March 20, 1957 [March 26, 1956], No. 9210/57. Divided out of 853,110. Class 75(1). [Also in Groups XII and XXVI] In a gas turbine, the liquid fuel is applied to the surface of a rotating disc from which it is thrown off centrifugally as a liquid sheet, into the high velocity air stream from the compressor. The fuel is thus atomised and mixed with the air in the flame tube. A secondary air stream from the compressor passes between the flame tube and the turbine outer casing and part mixes with the combustion gases in the turbine and part flows back towards the flame tube inlet by a passage in the flame tube inner wall which is cooled thereby. The fuel spraying disc is slightly coned inwardly to cause the fuel to adhere by centrigufal force. As shown, the turbine 10, 12 is supplied from the flame tube 31 which receives air from the compressor 6, 8 driven by 10, 12 through shaft 14. The fuel is led into 31 from hollow shaft 23 through ports 45, 47, to the downstream surface of the disc 24. The latter rotates with 14 and the ports are dimensioned so that the fuel is thrown from the disc periphery as a sheet into the airstream at 36. Turbulence is increased by the paddles 51. The air flow from 6, 8 is divided by the flame tube outer wall 32 into two annular streams, one through duct 35 and the other into 31. The inlet to 31 is divided by fingers 36, which may be shaped to meter the air-flow. The outlet from 31 is a number of channels 56 formed by corrugations spaced apart circumferentially in 32 to provide alternating passages which discharge streams of hot gas and air. The inner wall 33 of 31 is cooled by air pumped by fan 61 from 56 through holes 62, into passage 60. Specifications 723,015 and 853,109 also are referred to.

IPC: F16H3/72
Filed: 1940-05-27
Abstract: 544,251. Variable-speed gearing. SCHMID, F. May 27, 1940, No. 9284. Convention date, May 27, 1839. [Class 80 (ii)] In an epicyclic gear a shaft 1a having a sun pinion 3 is driven at variable speed from a shaft 1 having a sun pinion 2 by varying the speed of the planet pinion carrier 7, 8 by throttle control of the delivery from axially arranged plunger pumps 31 the cylinder block 10 of which is fixed to a casing 9 secured to the carrier 7, 8. The pump pistons 31 are connected to a wobbler disc 26 having a gimbal connection with the casing 9 and mounted on bearings 25 so as to be rotatable about an axis inclined to the axis of the shaft 1. The casing 9 and the parts connected thereto are rotatably mounted by bearings 11, 12, 13 upon a fixed sleeve 14. The pump cylinders 32 are inter-connected by a duct 55 and, in the latter between each pair of cylinders is a throttle valve 56, Fig. 9. The latter is cylindrical and has a port 57 corresponding to the duct 55 and a coned sealing face 58 pressed into contact with a sealing face 60 by a spring 59. At its end the valve '56 has a bevel pinion 64 meshing a gear 65 linked to a sleeve 71 so that axial movement of the latter by means of a hand lever 74 produces rotation of all the valves 56. The block 10 has a pressure chamber 39 supplied by an auxiliary pump 43 actuated by a fixed eccentric 50. Ducts 40 from the chamber 39 lead to the cylinders 32 so as to register with a circumferential groove 33 and diametral duct 34 in the pistons 31 when the latter are at the end of their suction stroke. The ducts 34 are connected to the cylinders 32 through spring controlled valves 38. Leakage losses are thus made up by flow past the valves 38. A pressure control valve 53, Fig. 8, is fitted to the pressure chamber 39.

IPC: F41A3/40
Filed: 1967-02-28
Abstract: 1,182,454. Firearms. B. CIVOLANI. 28 Feb., 1967 [9 March, 1966], No. 9481/67. Heading F3C. A firearm comprises a breech mechanism slidable within a breech frame 7. The breech mechanism consists of a bolt head 1 mounted slidably within a breech bolt 9, spring 10 being interposed therebetween and tending to urge the head 1 away from the bolt 9. The bolt head 1 is locked in its firing position by a nib 3 which engages with one end in recess 15 in the bolt head, the other end of the nib being formed with a foot 5 preferably having four flat faces 16, 17, 18, 19. In the locked firing position the face 16 engages an abutment 6 of the breech frame 7. On firing the firearm, for example, through the hammer 23 striking the firing pin 14, the firearm recoils and, in response to the recoil, the breech bolt 9 is urged forwardly against the spring 10 to delay the unlocking of the bolt head 1, (Fig. 2, not shown). The breech bolt 9 is then urged rearwardly by the compressed spring 10 and by the residual gas from the fired cartridge, a face 22 of the breech bolt 9 engaging the face 18 of the nib foot 5 to slide the face 17 over the abutment 6 and withdraw the forward end of the nib 3 away from the bolt head recess 15, thus unlocking the bolt head 1, (Fig. 3, not shown). The bolt head 1 then recoils away from the breech to eject the spent cartridge.

Filed: 1934-03-28
Abstract: 427,363. Change-speed gearing; claw clutches. STANDARD MOTOR CO., Ltd., and GRINHAM, E. G., Canley, Coventry. March 28, 1934, No. 9623. [Class 80 (ii)] Relates to change-speed gearing with synchronized clutches in which a pin such as 32, Fig. 3, in a cross slot 30, 31 thrusts an auxiliary friction clutch 27 momentarily into engagement to synchronize. An additional or auxiliary member 21, Fig. 1, is provided which is splined at 20 on a shaft 19 and supports both the friction clutch member 27 and the claw member 12. The claw member 12 is splined at 14, Fig. 2, on the auxiliary member 21 and carries the pin 32 which may be formed, as shown in Fig. 3, by cutting away unnecessary splines and parts of splines and leaving two part splines. The friction clutch member 27 is adapted for a limited turning without axial sliding relatively to the member 21. In the double-synchronized clutch arrangement shown, the two friction clutch parts 27 are rigidly connected by a bridge-piece 28, Fig. 2, which passes through a wider opening 23 in the member 21 and carries the cruciform slot 30, 31, Fig. 3, engaged by the pin 32. A spring ball 33, Fig. 1, normally holds the parts in neutral. When the claw sleeve 12 is moved, say, to the left of Fig. 1 by a fork engaging a groove 13, the pin 32 in the cross slot 31 carries the friction members 27 and auxiliary member 21 to the left until there is frictional engagement with a friction cone 25 on the coacting claw member 15. This frictional engagement is effecting synchronization of the claws 12, 15 while the pin 32 is slipping into the axial slot 30. As the pin 32 slips along the slot 30, the claw sleeve 12 is sliding into full engagement with the claws 15.

Patent HK-137196-A (HK)
Title: Polyphonic coding
Inventor: HOLT CHRISTOPHER ELLIS
IPC: H04S1/00
Filed: 1996-07-25
Abstract: A polyphonic (e.g. stereo) audioconferencing system, in which input left and right channels are time-aligned by variable delay stages (10a, 10b), controlled by a delay calculator (9) (e.g. by deriving the maximum cross-correlation value), and then summed in an adder (2) and subtracted in subtracter (3) to form sum and difference signals. The sum signal is transmitted in relatively high quality; the difference signal is reconstructed at the decoder by prediction from the sum signal using an adaptive filter (5). The decoder adaptive filter (5) is configured either by received filter coefficients or, using backwards adaptation, from a received residual signal produced by a corresponding adaptive filter (4) in the coder, or both. Preferably, the adaptive filter (4) is a lattice filter, employing a gradient algorithm for coefficient update. The complexity of the adaptive filter (4) is reduced by pre-whitening, in the encoder, both the sum and difference signals using corresponding whitening filters (14a, 14b) derived from the sum channel.
