Title: Improvements in or relating to fluid sealing devices
IPC: F16J15/36
Filed: 1954-11-02
Abstract: 771,254. Stuffing-box substitutes. CARRIER ENGINEERING CO., Ltd. Nov. 2, 1954 [Nov. 2, 1953], No. 31725/54. Class 122 (5). A fluid seal for a rotatable shaft 12 comprises a resilient sleeve 26 having a constricted portion 28 held in sealing contact with the shaft by a constricted portion 42 of a shell 34 and integrally connected by an intermediate portion 32 with an enlarged end portion 30 engaging a rotatable sealing ring 46 and embraced therewith by a collar 50 drivingly connected to the shell 34 by means permitting relative axial movement between the collar and shell, e.g. by lugs 43 on the end of the shell engaging axial slots 60 in the collar. The shell 34 has a shoulder 40 forming a support for one end of the sleeve 26 and terminates at its end remote from the sleeve in a flange 36 adapted to abut a shoulder 66 on the shaft. Axial grooves 54 on the periphery of the ring 46 are engaged by indentations 52 on the collar 50 which is shouldered at 56 to press a washer 58 against the portion 30 of the sleeve 26. The rotatable sealing ring 46 is urged into facial contact with a sealing surface 22 on a cover-plate 20 secured to shaft housing 10, by a spring 44 compressed between the flange 36 and the collar 50. To assemble the seal on the shaft the collar 50 may be initially rotated relative to the shell 34 so that the lugs 43 do not register with the slots 60 and then, with the inner edge 62 of the collar abutting the lugs, the seal is pushed along the shaft until the flange 36 abuts the shoulder 66 on the shaft; the collar then being rotated until the lugs register with the slots and the collar abuts the spring 44. The cover-plate 20 is finally assembled on the shaft housing 10, compressing the spring 44 so that the lugs 43 occupy a position intermediate the slots 60. If desired, the seal may be inserted on the shaft with the lugs and slots in register and rotation of the collar to cause the lugs and slots to be out of register deferred until resistance to movement of the seal along the shaft causes compression of the spring 44.

Abstract: 1374083 Pipe joints ROLLS-ROYCE (1971) Ltd 28 June 1972 [7 July 1971] 31807/71 Heading F2G  In order to eliminate differential thermal expansion between a duct 16 and a connecting flange 14, hoop stresses, tending to enlarge the aperture 12 of a pressure vessel 10, are counteracted by forces acting in a frusto-conical ring 26, which is held against expansion either by a rigid abutment ring 28 or by fulcra 44. On exerting a pull in direction 34, (Fig. 4), bellcrank lever 42 applies an inward thrust to sheet metal ring 26. Similarly, in Fig. 1, the tie bars 34 become loaded when the vessel 10 and the duct 16 are filled with a fluid under pressure and they exert an axial pull tending to flatten ring 26. Since the ring 26 is prevented from expanding outwardly, by ring 28, the axial pull causes it to contract inwardly against the abutment face 24 of the aperture.

Abstract: 1427184 Gas turbine combustion chamber STAL-LAVAL TURBIN AB 5 July 1973 [7 July 1972] 31976/73 Heading F1G [Also in Division F4] In a fluidized bed combustion chamber 6 for a gas turbine engine, dampers 5 and 14 respectively controlling entry of combustion air to the bed 9 and of a cooling gas, e.g. air, to a chamber 16 surrounding the bed for circulation via pipes 17 through the bed, are controlled to maintain constant the ratio of the amounts of the combustion air and cooling air, e.g. at 1:2; and by also controlling the combustion air and fuel supply together, complete combustion of fuel occurs at a bed temperature in the range of 700-950C, preferably at 850C. As shown, the combustion air and cooling air enter together through a valve 2 controlled together with a fuel valve 21. The fuel may be liquid, pulverulant or gaseous. The pipes 17 discharge the cooling air to a chamber 11 where it mixes with the exhaust gases from cyclone separators 10 to drive a gas turbine 20, which may drive a compressor. A by-pass 25 short circuits the fluidized bed and allows rapid cooling of the turbine. The two gas streams from the pipes 17 and separator 10 respectively may be kept separate as shown in broken lines at 23, with the cooling air driving a second turbine. A separate air, or other gas, source 24 may be used for cooling, as may water vapour when the combustion chamber acts as a super-heater for a steam turbine. The separate cooling air may be controlled in accordance with the combustion chamber temperature to maintain this constant.

Abstract: 159,687. Pochin, F. H., and Pochin, H. S. Dec. 20, 1919. Pulling-over.-In a machine of the type described in Specification 3301/10, an additional pedal is provided by means of which (1) the toe and side pincers are retained normally open; (2) they are successively closed; and (3) thereafter, a partial relaxation of the grip of the toe pincers can be obtained. As shown, the additional pedal 29 controls rocking levers 20, 22 engaging, by adjusting-screws, the pedals 7, 9 of the side and toe pincers, respectively. The lever of the pedal 29 has a cam-surface 31, concentric with its pivot, which engages rollers at one end of the rocking-levers to retain the pedals 7, 9 normally depressed, and therefore the pincers normally open. When an upper has been engaged in the pincers, the pedal 29 is slightly depressed to bring a gap 32 under the roller of the rocking lever 22 and cause the toe pincers to close. Further depression of the pedal 29 causes the side pincers to close. If it is then desired to relax the grip of the toe pincers, the pedal 29 is still further depressed, a step 33 then raising the roller of the lever 22. Strips 34, 35 on cams 15, 16 depress the pedals 7, 9 at the end of the cycle of operations, to allow the pedal 29 to return to starting position.

Title: Improvements in or relating to Fuel Injection Pumps for Internal Combustion Engines.
IPC: F02M41/12
Filed: 1967-07-13
Abstract: 1,187,074. Fuel injection pumps. ROBERT BOSCH G.m.b.H. July 13, 1967 [July 19, 1966], No.32185/67. Heading F1A. In a fuel injection pump of the type in which output is regulated by means of a by-pass or spill valve actuated by pressure generated by an auxiliary pump, return flow of the actuating liquid and hence the return of the valve towards its initial position being controlled by a throttle, a second by-pass passage is opened by the pump plunger before the by-pass valve opens, during conditions under which the by-pass valve returns to its initial position. The plunger 1 is reciprocated and rotated and comprises an injection portion 1a operating in an axially adjustable cylinder 2 and controlling inlet ports 46, a distributing portion 1C having a port 12 distributing to outlets 13 in succession and a portion 1b forming the auxiliary pump and having grooves 16 controlling the flow and return of actuating liquid to the by-pass valve 5 which regulates the spill from the chamber 3 via the passages 9, groove 6, passages 30a and 31 to the inlet chamber 11. The groove 6 also communicates with grooves 7 which appropriately connect with inlet 10 from chamber 11. The groove 6 also connects with a groove 33 towards the end of the plunger stroke providing a second spill or by-pass valve, groove 33 connecting via passage 32, normally open valve 34 and passage 32a with the chamber 11. Valve 34 is held open during normal running by pressure in the chamber 11 but during starting is held closed so that maximum fuel is delivered. The arrangement is such that the by-pass 6, 33 opens before the by-pass 30a, 30b when the valve 5 starts from its stop 28 or from a point closely adjacent thereto i.e. under low speed operation of the engine. In a modification Fig. 3 (not shown) the auxiliary pump chamber is by-passed through a passage throttled by the valve 34 during starting so that the valve 5 cannot be operated. Should the valve 34 stick the throttled aperture would allow the valve 5 to operate before excessive speed is reached. In a further modification Fig. 4 (not shown) the plunger portion 1a has ports which function as the second spill or by-pass, which ports co-operate with normally open ports in the cylinder 2. During starting these latter ports are closed by a spring pressed sleeve surrounding the cylinder 2 but which is raised to open the ports by the pressure from the feed pump.
