Title: Improvements in valves controlling fluid flow
IPC: F16K31/122
Filed: 1958-01-24
Abstract: 864,634. Valves. BUNYAN, T. W. Nov. 25, 1958 [Jan. 24, 1958], No. 2426/58. Class 135. A pair of identical fluidactuated valves 11, 12 are disposed in a body incorporating a central chamber 3 leading to a tank, not shown, and opposed chambers 4, .5 symmetrically disposed with respect to chamber 3 and respectively connected e.g. to ballast-water and fuel-oil supplies. Opposed cylinders 19, 20 and parts 17, 18 are bolted to the chamber walls, the valve stems 13, 14 sliding in glands 16 in the parts 17, 18, which glands may comprise two spaced members, the space between which is vented to atmosphere; valve-stem extensions 22 slide in glands 24 in the cylinder end-plates 25 and project beyond the ends of the latter. Slidable in the cylinders 19, 20 are pistons 28, 30, the former being attached to the valve stems and loaded by a spring 30 confined between the piston 28 and an abutment plate 32 whilst pistons 34 are free to slide on the extensions 22. Each cylinder has three ports 38, 39, 40 for the selective introduction of operating fluid into the space 42 in front of the piston 28, the space 44 between pistons 28, 34, and the space 46 outwardly of piston 34. The supply of operating fluid is connected to each space 42 via a valve means formed between the extension 22 and end plate 26 of the other valve 11 or 12 so that one of these valves must be closed before the other one can be opened. Either valve may be manually actuated upon pivoting a yoke 55 to bring a bush 59 into engagement with a groove 60 in the extension 22, the bush being attached to a threaded rod 56 carrying a hand wheel 58. Oil may be introduced into or withdrawn from the tank only when valve 11 is closed and upon admitting operating fluid to the space 42 via the valve means between the extension 22 and end plate 26 of valve 11, and the port 38 whereupon piston 28 is moved against spring 30 to open valve 12 and place chambers 2, 3 in communication. Upon admitting operating fluid into space 46 the piston 28 and valve 12 are moved towards the closed position until piston 34 engages the plate 32 ; complete valve closure ensues when operating fluid is supplied to space 44. Opening of valve 11 can be brought about in a similar manner. Should the operating fluid supply fail the valve will be closed by the spring 30 and subsequent operation is effected by the hand wheel 58. When the valves control high-pressure liquid they are provided with skirts 63 slidable in projections 66 of the parts 17, 18. Pressure balancing passages 70 may interconnect the two sides of each valve head.

Patent GB-562401-A (GB)
Title: Improvements in or relating to means for the indication of ice formation in carburettors
IPC: F02M69/00
Filed: 1941-02-27
Abstract: 562,401. Carburetters; alarms. BEALE, E. S. L., and MUNTZ & CO., Ltd., A. Feb. 27, 1941, Nos. 2675 and 4650. [Classes 7 (ii) and 7 (iii)] If icing-up occurs, a warming or de-icing device is set into operation by means sensitive to variations in the velocity of flow of combustible mixture through the passage leading from the carburetter to the supercharger. A miniature auxiliary intake system 20 is provided between the main intake 17, 19 and the supercharger inlet 12, and is provided with a throttle 21 coupled to the main throttle 15, which is adjusted by the usual automatic boost control 62, 65, 26. There is no petrol in the system 20, so that it is not likely to become iced up, but ice may form in' the main intake system, in which case, if the throttle 15 is not already fully open, it is opened wider by the boost control so as to maintain the supercharger pressure constant. The throttle 21 is consequently opened. wider also, and the flow through the system 20 thereby increased, this increase causing operation of a diaphragm 43 to close the switch 50, 51 of a warning-lamp 57. The flow in the system 20 is registered by a nozzle 33, Fig. 2, opening downstream into the supercharger inlet, and the pressure in a space 37 behind the nozzle is conveyed to one side of the diaphragm 43 by a pipe 38. The flow in the supercharger inlet is measured by a Pitot tube 39 opening. upstream therein, and connected to the other side of the diaphragm by a pipe 40. The switch 50, 51 may bring into action a de-icing valve 58 admitting alcohol under pressure to nozzles 60. Correction for altitude is afforded by a capsule 52 controlling. the position of the contact 50 relatively to an inclined face on the contact 51. If the throttle 15 should become jammed with ice, the liquid pressure operating in the servomotor cylinder 27 will increase sufficiently to collapse a capsule 75 and close a switch 73 controlling a warning- lamp 77. This action is prevented, when the throttle is fully open, by the servomotor piston 26 opening a switch 70, 71, or when the throttle is set below the rated boost, by the pilot's control rod 61 opening a switch 78 through the disengagement of a cam 79. A replaceable constriction 29 is provided in the pipe 20. In a modification, the pressures acting on opposite sides of the diaphragm 43 are taken from venturis in the main and auxiliary intakes, and the switch contact 50 is arranged to operate between two fixed contacts 51, one to the right operating as that shown in Fig. 1, and another to the left which comes into action if the pipe 20 should become blocked with ice. Specifications 414,410 and 423,510 are referred to.

Abstract: 1,195,334. Curve-describing instruments. DENYS FISHER GROUP Ltd. 10 Jan., 1969 [18 Jan., 1968], No. 2756/68. Heading B6P. A curve-describing instrument comprises a toothed primary member 2 in the form of a ring, and a toothed secondary member 4 in the form of a disc, the width of the teeth on the primary member and/or the secondary member being less than the width of the peripheral surfaces on which they are formed so that a peripheral flange 12 is formed adjacent the teeth. Different modes of operation exist, utilizing a writing instrument inserted into one of the holes of the primary or secondary members to act as a driving member. In (Fig. 3), with the flange 12 contacting the writing surface, it is impossible for the teeth of the members to mesh, so that circles are drawn in similar manner to that of Specification 1,154,653. In (Fig. 4) the flange 12 is uppermost so that it is possible for the teeth of the members to mesh. In this case operation is similar to that described in Specification 1,024,438.

Title: Improvements in internal-combustion engines of the free-piston type
IPC: F02B75/02
Filed: 1942-03-02
Abstract: 578,436. Two-stroke engines. MUNTZ & CO., Ltd., A., and FARMER, H. O. March 2, 1942, No. 2759. [Class 7 (ii)] [Also in Group XXVIII] In a compression-ignition engine of the freepiston type, a fuel-injection pump is operated, or one of the limits of its delivery period is timed, by an oscillatory inertia member connected to the primary moving parts of the engine; energy is stored in the inertia member during the first part of the stroke of the moving parts and the inertia member is afterwards retarded, and its kinetic energy is transmitted to means for operating or timing the pump. As shown in Figs. 1 and 2, a two-stroke freepiston air compressor comprises opposed pistons 26, 29. in a power cylinder 20 having inlet and exhaust ports 21, 22; the inlet ports communicate with a scavenging-air receiver formed by the casing 23. The piston 26 is connected by a rod 27 to a piston 28 in a double-acting aircompressor cylinder 24 discharging at 50 into the receiver 23 and at 48 to a receiver (not shown). The piston 29 is connected to a cushioning piston 31 in the cylinder 25. For synchronizing, crossheads 36, 37 are maintained horizontal by arms 38, 39 sliding in guides 40, 41 and are connected by limbs 34, 35, 42, 43 to levers 32, 33 oscillating about a common axis. A fuel-injection nozzle 44 is supplied from a pump 45, Fig. 6, actuated by an arm 53 on the pivot shaft 52 of the synchronizing lever 33. An inertia lever 54, pivoted at 55 to the arm 53, has an eye 56 movable about the shaft 52 and is weighted at 57. The tappet 58 actuating the fuel pump 45 is connected by links 59 to the inertia lever, so as to follow the vertical component of displacement of the midpoint of the lever, the movement of which is checked by a laminated buffer spring 62 fixed on the arm 53 and engaged by a pin 63 on the lever when the latter nears one end of its displacement. Similar buffer springs mounted on the casing _co-operate with lugs on the links 59. In the opposite direction the lever is checked by a hydraulic dashpot having an element 64 mounted on the arm 53 and the other element 65 having a pin-and-slot connection 66 with the lever. Kinetic energy is stored in the lever 54 during acceleration of the arm 53 and subsequently given up to the pump plunger, as indicated by a graph, Fig. 8 (not shown). The invention may be similarly applied to a timing device for determining the begining or end or both of the fuel-injection period in a free-piston engine having a pump actuated by other means, for example by a small gas engine energized by working fluid compressed in the engine combustion chamber, as described in Specification 536,671, [Group XXVIII].

Abstract: 952,240. Making tubular electric lamps; turret machines. GENERAL ELECTRIC CO. Ltd. Jan. 17, 1963 [Jan. 26, 1962], No. 3024/62. Headings H1F and H1J. In a method of pinch sealing and pumping the envelope of an electric lamp having a tubular vitreous envelope with a filling of inert gas and a pinch seal at each end, especially a high-pressure mercury vapour discharge lamp, the filling gas is fed continuously into the envelope through a pumping stem, the ends of the envelope are pinch sealed during the filling and the pumping stem is sealed off without the envelope being subsequently open to the atmosphere. The pumping stem may have a closed side tube in which is a globule of mercury which is tipped into the envelope after the stem has been sealed off, the stem being then finally sealed off close to the envelope. In a turret machine for carrying out the process, an electrode 5, Fig. 1, is fed to a support 2 on the turret at P1, the envelope 3 is mounted vertically over the electrode at P2 with its pumping stem 7 inserted in a head 9 connected by a plate valve 13 to a source of argon, the top of the envelope 3 being closed by a loose plug and argon is fed into the envelope at P3 while nitrogen or argon is fed to the bottom of the envelope through the support 2 and a manifold 19 also connected to a source of supply through the plate valve 13. At P4, the lower end of the envelope is heated by burners 23 and at P5 the softened quartz is squeezed by punch hammers 24 sealing the end on to the molybdenum foil lead in conductors of the electrode 5. The envelope is cooled at P6 and inverted at P7, a second electrode being fitted to the open end. Scaling and punching is then carried out similarly at P8 and P9, the central part of the envelope being also heated at P8, and the tube being cooled by air jets 30 at P10 and P11. The pressure of argon in the envelope is reduced at P12, the stem 7 is sealed off at P13 and the tube unloaded at P14. The mercury contained in a side tube 8 on the stem 7 is then tipped into the envelope and the stem 7 finally sealed off close to the envelope. The operations are effected by suitable cams (not shown).

Abstract: 370,094. Gramophones. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and CHANTRILL, J. J., 22, Kensington Road, Carlsdon, Coventry. Feb. 2, 1931, No. 3318. [Class 40 (ii).] Relates to a sound-reproducing machine in which two sound-boxes or pick-ups are mechanically interconnected and means are provided whereby when one sound-box or pick-up becomes inoperative the other is brought into use. The pick-ups or sound-boxes may be adapted for use with a single turntable or to engage records on different turntables. As shown in Fig. 1, two pick-ups A, B are movable on pivots C in carrier arms D, E, respectively, and the arms D, E are interconnected by a link G. The arms D, E are provided with insulated contacts f<1>, f<2> which co-operate with fixed contacts e<1>, e<2>, respectively. Fig. 2 shows the supporting means for the pick-up B, which comprises a lever d<2> attached to a member g<2> rigidly secured to the pick-up. The angle between the members d<2>, g<2> is adjustable by means of a screw h. The lever d<2> has an armature k<2> which is attracted when an electromagnet b<2> is energized and this causes lever d<2>, member g<2> and the pick-up C to move about the pivots C, and a latch c<2> then engages the end of the lever d<2> to maintain the pick-up in its raised position. When the pick-up is to be lowered, an electromagnet a<2> is energized which withdraws the latch c<2> to allow the pick-up to be lowered by gravity into engagement with the record. In operation, as the pick-up A traverses the record for reproduction, the pick-up B, in its raised position, is moved towards the outer edge of the record. When the pick-up A reaches the inner groove, the contact f2, e2 engage to energize the magnets b<1>, a2. Pick-up A is thus raised from the turntable and secured by the latch c<1> while the pick-up B drops on to the turntable, as the latch c<2> is actuated, and then commences to traverse the record.
