Title: Carburation system for an internal combustion engine
IPC: F02D35/00
Filed: 1976-06-10
Abstract: 1526516 Air/fuel ratio control B LAPRADE X LAPRADE and P GELE 10 June 1976 [18 June 1975] 24034/76 Heading F1H The air/fuel ratio of the mixture supplied by a constant vacuum type carburetter is modified by moving the metering needle relative to the piston, in dependence on the composition of the exhaust gases. Piston 6 is open to atmospheric pressure on its under-surface 6b and its upper surface 6a is acted on by the partial vacuum in chamber 31 which communicates through passage 25 with the space upstream of throttle valve 2. The piston is biased by compression spring 38. A cap 28 is fitted inside piston 6 and, with diaphragm 27, defines chamber 30 which communicates with chamber 31 through orifice 32. The underside of diaphragm 27 is open to atmosphere through vent 5 and the diaphragm is biased by compression spring 27a. Stem 26 connects diaphragm 27 to needle-holder 37, needle 4 is adjustable by screw 39. Chamber 30 is connected by orifice 17a, flexible tube 17 and pipe 17b to buffer tank 18 and hence to electromagnetic valve 13 which has an inlet 19 open to atmosphere. Exhaust gas sensor 15 provides an electrical signal representative of exhaust gas composition to control unit 14 which provides an operating signal to valve 13. If the mixture is too rich, valve 13 opens, so that the pressure in chamber 30 increases and needle 4 moves relatively to piston 6 to decrease the amount of fuel in the mixture. At small throttle openings needle holder 37 is very close to the fuel supply orifice and to avoid interference with the fuel flow the needle holder is slotted to provide air-flow passages. The force available to move the needle holder may be increased by providing pipe 40 which connects buffer tank 18 to the inlet manifold downstream of throttle valve 2, a restriction 34 being provided in the pipe.

Title: Improvements in and relating to acoustic diaphragms and to the manufacture thereof
IPC: H04R7/02
Filed: 1933-08-31
Abstract: 411,331. Diaphragms. McKAY, R. F., Fort Dunlop, Birmingham.-(International Latex Processes, Ltd. ; 10, Lefebvre Street, St. Peter's Port, Guernsey, Channel Islands.) Aug. 31, 1933, No. 24139. [Class 40 (iv).] Acoustic and like diaphragms, preferably of conical form, are manufactured from a mixture of cotton fibre or wood pulp, together with a binder of a natural rubber dispersion produced from natural latex. Trinidad asphalt and resins may be added as fillers. The cotton fibre or wood pulp is beaten up with water in a paper-maker's beating-machine, after which a small amount of alkali may be added, followed by the latex. A dilute solution of an acid or acid salt is then added after thorough mixing, in order to form a binding coating of the latex all over the fibre or the pulp. The liquid thus formed is circulated through a vat 1 and maintained at constant level therein. A reversible frame, carrying oppositely-disposed rows of moulds 12 connected through pipes 9 to suction apparatus 42, is raised out of and lowered into the tank on guides 3 by fluidpressure piston-apparatus 18, 19 controlled by valves 22-25 operated by a cam-actuated lever 26. When the lever 26 is raised to open the valves 22, 23, fluid pressure is admitted to the pistons to raise the moulds, while when the lever is lowered, the exhaust valves 24, 25 are opened to allow the moulds to descend by gravity. By reversing the mould-carrying frame one set of moulds can be removed or the articles stripped therefrom while the other set is being dipped. The rate of withdrawal of the moulds can be varied at different points to vary the thickness of the deposit at different points of the diaphragm. The moulds preferably are removed and passed through a hot-air drying-apparatus while the diaphragms are still on them. Finally the dried diaphragm is pressed in heated finishing dies which may also impress a pattern or design upon parts of it. The periphery of the diaphragm may be corrugated and the rim and apex may be dipped into latex before being pressed in the dies. Specification 359,950, [Group V], is referred to.

Filed: 1967-05-25
Abstract: 1,127,728. Bearings. ENTWICKLUNGSRING SUD G.m.b.H. 25 May, 1967 [7 June, 1966], No. 24472/67. Heading F2A. A race of a ball or roller bearing is moved axially to accommodate changes in the bearing temperature. In an embodiment, tube sections 1, 2 and 3, Fig. 9, of a jet deflector of a jet engine have lugs 4, Fig. 1, each of which has a bar 5 pivoted thereto. The bars 5, which are made of a material having a high expansion coefficient, are also connected to lugs 6 on a control-ring 7. The latter is provided with racks 8 which mesh with pinions on axial adjustment screws 9, so that an outer race 10, Fig. 2, for example, may be moved axially to maintain the required bearing clearance by means of the change in length of the bars 5 and the corresponding rack-andpinion movement effected thereby. In another embodiment a control-ring 19, Figs. 5 and 6, actuates a lever 20 which travels through an angle corresponding to the change in length of the members 5 and rotates an eccentric 21. The eccentric 21 is located between the outer races 10 of the bearing and is actuated in accordance with the variation in length of the bars 5 to provide the necessary bearing clearance. Cooling air may be passed between the inner and outer races of the bearing. In a further embodiment, a control assembly 30, 50, Fig. 9, which is connected to an electrical source through a conductor 33, replaces the bars 5 and maintains the required bearing clearance by means of a servo-force. In use, a control unit 30 is connected by electrical measuring circuits 31 to the tube sections 1, 2 and 3 and to a bearing-cover 14, Fig. 2, and senses the temperature correction required. A force amplifier 50 is controlled accordingly to effect the required movement of the bearing races, via conductors 32. The bearing-cover 14 is provided with splines 15 which engage grooves in the outer race 10 so as to prevent the latter from rotating.

Abstract: 798,523. Transistor amplifier stabilizing circuits. GENERAL ELECTRIC CO. Aug. 25, 1955 [Aug. 27, 1954], No. 24479/55. Class 40 (6). In a two-stage push-pull amplifier, a temperature sensitive resistance, which may be a transistor, is connected across the input of the second stage to by-pass a varying part of the output of the first stage. Input is applied in parallel to two complementary transistors 14, 15, Fig. 1, directly connected to a further pair 21, 22 feeding in parallel, a load 25. Negative temperature-sensitive resistors 19, 20 are connected between the bases of the transistors 21, 22 and the junction may be earthed. A further resistor 27 with an earthed variable tap 30 is also connected between the bases. A feedback connection is taken from the point 28 to the tap 18 on resistor 16 to provide D.C. stabilization. The position of the tap 18 on resistor 16 is adjusted at a low temperature so that no D.C. potential appears across the load 25. An adjustment of the tap 30 is made with the amplifier operating at the upper end of its temperature range. In a modification, Fig. 2 (not shown), the resistor 27 is included between the ends of the resistors 19, 20. In a further modification, Fig. 3, the temperature sensitive element is the transistor 40 of a type similar to that used for transistors 14, 15. The value of the resistors 41, 42 may be adjusted in the same manner as tap 30 on resistor 27. A NPN transistor may be employed with the base and collector connections interchanged. The circuit is arranged to operate in class B when any tendency for one or other of the transistors to be biased beyond cut-off would result in distortion, particularly at low level.

Abstract: 507,460. Fluid-pressure servomotor-control systems. JUNKERS FLUGZEUG-UNDMOTORENWERKE AKT.-GES. Aug. 24, 1938, No. 24919. Convention date, Sept. 11, 1937. [Class 136] [Also in Group XXIV] An automatic gear-changing device for two-speed gears, for use more particularly with superchargers on aircraft engines and operating in accordance with changes in an atmospheric condition, e.g. changes in pressure or temperature, comprises a quick-change device which is adapted to move from one end position to the other under the action of an auxiliary force controlled by the atmospheric condition and, in so doing, effects the changing of the gear either directly or indirectly. The invention is described as applied to gearing comprising driven pinions on the supercharger shaft in engagement with idle pinions on a driving shaft, a slidable clutch non-rotatably mounted on the driving shaft being interposed between said idle pinions. The slidable clutch (not shown) is actuated by an oscillating vane 61 which is mounted in a housing 60 and is coupled to the clutch by a lever 62 and rod 63, movement of the vane being effected by pressure fluid under the control of a piston valve 69 located in a chamber 85 which is provided with a pressure fluid inlet 70, outlets 71, 72 and pipes 65, 66 leading to opposite sides of the vane. The piston valve is provided with a mechanical quickchange device constituted by spring- pressed balls 104 in engagement with projections 102 in the valve chamber, and the latter is formed with an extension 96 housing a bellows diaphragm 94 which contains atmospheric air and carries a check valve 91 to coact with an orifice 86 which leads from the main valve chamber 85 to a chamber 88 having an outlet 89 leading to a continuously-operating pump 75 supplying the valve inlets 71, 72. With the valve 69 and vane 61 in the positions shown, the low gear is set for low-altitude working, pressure fluid being supplied from the pipe 70 to the pipe 66, and excess fluid being returned to the pump 75 through a bore 78 in the valve 69, the orifice 86 and the pipe 89. Simultaneously the pipe 65 is in communication with the outlet pipe 71. When a higher altitude is reached, however, the diaphragm 94 expands and causes the valve 91 to close the orifice 86, whereupon a pressure builds up in the chamber 85 and effects movement of the valve 69 against the pressure of a spring 106, putting the pressure pipe 70 into communication with the pipe 65, the pipe 66 into communication with the outlet 72, and operating the vane 61 to move the clutch into high-gear position. Means controlled by a governor 115, mounted on the engine shaft, are also provided for effecting a change into low gear at any time within the range of low airpressure in the event of excessive engine speed, said means comprising a valve 110 which is coupled to the governor and, when actuated, effects a reduction in pressure in the chamber 85. This change may also be effected by opening a hand-controlled valve 117.
