IPC: F02C7/32
Filed: 1959-11-26
Abstract: 888,320. Gas-turbine plant. ROLLSROYCE Ltd. Nov. 18, 1960 [Nov. 26, 1959], No. 40279/59. Class 110 (3). A gas-turbine engine has a front air intake portion which comprises an outer casing and an internal housing mounted within the casing by means of a plurality of struts, at least one of which is hollow, the casing and housing driving therebetween a passage through which air flows to the engine, the casing being readily releasable from the remainder of the engine, the casing having mounted externally thereon at least one engine auxiliary device which forms an operative part of the engine, drive transmission means for driving the engine auxiliary device or devices extending through a hollow strut, the drive transmission means being freely disengageable from a shaft disposed within the engine. The aircraft gas turbine jet-propulsion engine shown comprises a front casing portion 13 which is bolted to the casing portion 14 and so may be readily detached therefrom. Mounted on the front casing portion is a number of engine auxiliary devices including a centrifugal fuel pump 20, a filter and oil cooler 21, a fuel control unit 22, a backing pump 23, an emergency governor 24 and a pair of hydraulic pumps 25. Quillshafts 29 are utilized for transmitting drive from the compressor 17 to the auxiliary devices and they extend through certain of the hollow struts 28 which extend across the annular airintake passage 27 formed between the front casing portion and the bullet-shaped front bearing housing 26, the latter being supported from the casing portion by the struts. The quillshafts have bevel gears 30 at their inner ends, the bevel gears engaging with a bevel gear 31 on a shaft driven by the compressor. The engine auxiliary devices are disposed within a rectangular section housing 12 within which the engine is disposed, the housing being mounted either on the aircraft wing or fuselage. In Fig. 4, the engine auxiliary devices 36, 37, 38 are supported from the front casing portion of the engine by means of struts 40, 41 which extend through holes 42, 43, 44 in the wing or fuselage 39 within which the auxiliary devices are disposed. The quill-shaft 46 driving the device 37 extends through a hollow strut 28, but the quill-shafts 45, 47 are connected by bevel gears to quill-shafts 48, 49, these latter shafts extending through hollow struts 28.

Abstract: 889,922. Liquefaction of gases. CONCH INTERNATIONAL METHANE Ltd. Nov. 29, 1960 [April 18, 1960], No. 40917/60. Class 8(2). Liquefaction of a gas e.g., natural hydrocarbon gas is effected by dividing a stream of compressed gas leaving a multistage compresser 12 into a major stream which traverses a duct 34, a heat exchanger 36 cooled by an external refrigerant, an expansion turbine 40 and ducts 48, 50 leading to a heat exchanger 20 through which is passed the minor stream 18 of compressed gas to effect condensation thereof; the so warmed major stream being returned through a duct 10 to the inlet of the first stage compresser 12. The condensed inner stream is expanded to atmospheric pressure at a value 26 into a vessel 30 from which product liquid is discharged through a duct 32 and flashed vapour is fed through a duct 46 to the turbine exhaust and hence through the exchanger 20. Make-up gas under well-head pressure is supplied by a duct 42a to the inlet of the last compression stage or through a duct 42 to the turbine inlet.

Title: Improvements in Electrolytic Material Removal Method
Inventor: BERGER E
IPC: B23H9/16
Filed: 1966-09-14
Abstract: 1,162,648. Electrolytic removal of material. GENERAL ELECTRIC CO. Sept. 14, 1966 [Dec. 20, 1965], No. 41085/66. Heading C7B. A method of removing material electrolytically from an electrically conductive workpiece comprises directing a stream of electrolyte from a nozzle made of dielectric material towards a workpiece across a gap, causing the stream to be electrically charged by applying an A.C. or D.C. voltage between the workpiece and an electrode immersed in the electrolyte upstream of said nozzle, moving the electrode relatively towards the workpiece, maintaining said voltage at a level sufficiently high to maintain a condition at or beyond the threshold of glow discharge at the region of the workpiece upon which the stream impinges, said level not being so high as to permit sparking to occur directly between the electrode and the workpiece, and electrically contacting said stream along at least part of its length with an electric conducting means so as to dissipate a proportion of the charge carried by said stream, said proportion being dependent upon the length along said stream of said electrical contact, whereby increases and decreases in said contact length respectively cause the rate of material removal to decrease and increase to provide a stabilizing effect on said gap length. At the threshold of glow discharge, an increase in applied voltage produces a reduction in current. In electrolytically removing material from a workpiece 10, Fig. 2, e.g. to make a fluid spray head, streams of charged electrolyte are pumped through nozzles 14 as they are moved e.g. at a constant rate, towards the workpiece. The streams of electrolyte are contacted by a bath of electrolyte 18 which dissipates charge from them. All the nozzles are moved at the same time and at the same rate irrespective of whether or not they are starting to remove material, or at an intermediate position, or completing penetration of the work. In the process, pronounced funnel shaped entrances to the holes are not formed since there is a relatively sudden change from no material being removed to removal at a substantial rate. The electrolyte can be heated or cooled at 30 and 32. Where the electrolyte supplied through the nozzles and that used in the bath is the same, it may be recirculated, e.g. through a filter. By the process, holes may be formed in tubes, bars or plates of Ni base alloys using aqueous electrolytes containing 10 weight % H 2 SO 4  or 14 weight % HCl, voltages of 300-1200 with the current flow not exceeding 4 amps, an electrolyte temperature of 70-200‹ F. and a charged electrolyte stream directed under a pressure of 40-60 p. s. i.

Abstract: 1,101,702. Seed drills; harrows. BAMFORDS Ltd. 15 Oct., 1964 [18 Oct., 1963], No. 41174/63. Headings A1B and A1D. A seed drill of the kind described in Specification 788,214 has attached thereto a harrow the tines of which effect furrow closing. The harrow comprises a sub-frame 19 to which a tine carrying frame 29 is pivoted at 31 for movement in a vertical plane. Movement of the tines is controlled by two rods 34 passing through plates 33 mounted on the frame, and extending through apertures in abutment plates 35 fixed to the sub-frame. Compression springs 37 on each rod engage the abutment plates and are held between collars 38 which are adjustable longitudinally of each rod. Owing to these springs the tines and their frame in operation will be caused to vibrate by impact of the tines with irregularities in the ground. The seed drill is adapted to be mounted on the three point linkage of a tractor, and it may comprise wheels by means of which it is driven, or drive may be effected by the tractor p.t.o. shaft. The harrow may comprise one (Fig. 6 or two (Fig. 2) rows of tines.

Filed: 1958-12-29
Abstract: 870,848. Counting-apparatus. TYER & CO. Ltd. Dec. 29, 1959 [Dec. 29, 1958], No. 41860/58. Class 106 (1). In apparatus for counting and recording vehicular traffic, possible miscounts due to the " bounce " of contactor contacts operated by the vehicles are obviated by the provision of a high-speed relay which closes a contact to maintain a circuit for operating the slow-to-operate counter magnet. As described, a passing vehicle travels over a flexible tube (not shown) to close diaphragm-operated contacts A. A circuit is thus closed to energize a high-speed relay B whose contact B1 closes to complete a circuit for the counter magnet C which is maintained at least until the counter magnet is energized and opens a contact C1, thus preventing miscounts due to " bounce " of the contacts A. If the contacts A have opened, the circuit then returns to its initial state, but if the contacts A are still closed, the magnet C is maintained energized until the contacts A open. In addition to a counter (not shown), a stylus and drum recorder (not shown) may be provided, clock contacts E opening to cause resetting of the counter and stylus after predetermined time intervals.
