Title: Improvements in fuel feed control systems for gas turbine engines
IPC: F02C9/16
Filed: 1955-04-07
Abstract: 778,105. Variable pitch propellers. BENDIX AVIATION CORPORATION. April 7, 1955, [June 1, 1954], No. 10298/55. Class 114. [Also in Group XXVI] A fuel feed control system for a pilot operated gas turbine comprises a conduit for conducting fuel to the burner of the turbine, a fuel control valve for the conduit, an engine speed responsive governor having an adjustable speed setting and connected to the fuel valve and pilot operated means for slectively adjusting the speed-setting of the governor characterized by a pilot operated " reset " means for selectively adjusting the speed setting of the governor independently of the pilot operated governor adjusting means. As shown, the " reset " means comprises a fluid pressure operated piston 116 connected to a governor " reset " lever 90 and operable when the pilot opens a switch 154 in circuit with a solenoid operated valve 144. In changing from forward to reverse thrust of a propeller, the engine does not drop to normal idling speed but maintains a speed normal to partly open throttle operation. The throttle control valve 36 comprises an apertured cup 53 sliding in a sleeve 50 opposite an inlet port 59 therein and rotatable with respect thereto. The valve stem 55 extends through an extension 50<SP>1</SP> of the sleeve 50 to support at its lower end a retainer 76 for a governor spring 75 the top end of which is adjusted by the pilot's lever 24 acting through links 23, 22, a co-ordinating box 21, a link 79 and a lever 80 which turns a governor scheduling cam 82 to depress a cam follower 83 having a rack portion 88 adapted to turn the governor " reset " lever 90 to depress the upper retainer 77 of the governor spring 75 and open the valve. The downward movement is checked by one or other of an acceleration lever 93 actuated by engine speed and compressor inlet temperature or a part throttle lever 95 subject to the same controls plus the setting of the pilot's lever 24. At the same time, the compressor discharge pressure rotates a gear 109 meshing with a toothed sector 110 to rotate the valve. An engine driven centrifugal governor 61 controls the holder 57 of the governor spring retainer 76. When the pilot intends to use a reverse thrust he opens the switch 154 to de-energise the solenoid which holds closed the valve 144 in a pressure fuel line 146, permitting the fuel to pass to the device 114 consisting of the piston 116 having a threaded extension abutting a stop 126 to determine a normal idling position of the " reset " lever 90 ; the fuel under pressure displaces the piston to the right turning the lever 90 clockwise to increase the flow through the valve 36. Specification 753,305 [Group XXVI] is referred to.

Title: Improvements in automatic stop devices for printing presses and the like
IPC: B41F33/12
Filed: 1927-04-20
Abstract: 279,328. Holt, R. O. April 20, 1927. Stopping-arrangements. - A stop mechanism for printing, folding, and like machines, described as applied to a printing-machine in which a reciprocating bed 11 and cylinder 22 prints sheets fed from a pile 23<1> and delivered by bands 28 to a pile 23<a>, comprises an electric control mechanism for the driving-motor 15 of the press which stops the motor if a sheet is not fed to the machine and thus fails to pass under an electric contact 34, Fig. 2, or if the sheet jams and fails to pass away from the contact 34 at the correct time. An oscillating member 39 connected by a link 38 to a lever 13, which reciprocates the bed 11, is mounted on a roller 40 fitted with a contact 42, and causes the contact 42, which is earthed by connection with the machine frame, to engage a contact 45, Fig. 8, at one period and to press normally insulated contacts 50, 51 into engagement at another period. When the contacts 42, 45 touch, a circuit from battery 78 to an electromagnet 77 is closed if a weighted pivoted contact 34, Fig. 2, is in engagement with an earthed rod 29 below it, and this occurs when a sheet is missing. When a sheet is present, it prevents contact between the parts 34, 29, but causes the contact 34 to engage a contact 36 in the circuit containing the contacts 50, 51. Normally the contacts 34, 36 are disengaged by the passage of the sheet before the oscillating contact 42 closes the contacts 50, 51, but if the sheet jams, the contacts 34, 36, remain closed, and the electromagnet 77 is energized when the contacts 50, 51 close. When the electromagnet 77 is energised it releases a catch 76 which normally holds a pair of knife contacts 62 into engagement with the contacts 64 connected to the driving-motor of the machine. When the electromagnet 77 is energized the circuit containing battery 78 is automatically broken. The contacts 62 are opened under action of a spring 73, and are closed by a hand-crank 72.

Title: Improvements in or relating to emulsion copolymerization of unsaturated organic compounds and sulfur dioxide
Inventor: CROUCH WILLIE WOODWARD
IPC: C08G75/22
Filed: 1952-05-01
Abstract: <PICT:0719493/IV (a)/1> <PICT:0719493/IV (a)/2> Unreacted sulphur dioxide is recovered from the aqueous emulsion heteropolymerization of an unsaturated organic material with a stoichiometrical excess of sulphur dioxide by separating unreacted materials and passing them through a water bath to dissolve the sulphur dioxide and thus separate it from the water insoluble unreacted materials. Unsaturated organic materials, emulsifiers and catalysts which may be used are those listed in Specification 686,446.  In a preferred process unsaturated organic material, sulphur dioxide, water containing emulsifying agent and catalyst from chambers 11, 12, 13, 14, Fig. 1, respectively, are supplied to a reactor 15.  After reaction the emulsion is passed through pipe 17 to a heater 19, wherein the temperature is raised to between 140 DEG  and 185 DEG F., and then to a coagulator 23. Unreacted vaporizing materials are removed, preferably before coagulation and passed by pipe 32 and compressor 33 to a second reactor 35.  Water containing emulsifying agent and catalyst from chambers 13, 14, previously supplied to chamber 35, act as a filter, dissolving sulphur dioxide and allowing insoluble materials to pass through the liquid and be removed through valve 38.  The latex in chamber 23 is coagulated by pumping in coagulant from chamber 24 and in coagulum removed by pipe 39. Unsaturated material and additional sulphur dioxide from chambers 11, 12 are added to the mixture in chamber 35 so that the sulphur dioxide is in excess and the cycle is repeated, unreacted materials this time being passed into the first reactor 15.  In a modification, the materials from the chambers 11, 12, 13, 14, Fig. 2, are continuously supplied to a reactor 45 and the reaction product is passed through a heater 52 and then into a flash chamber 53 under reduced pressure. The gaseous products are passed by a compressor 55 to a scrubbing tower 56, where sulphur dioxide is dissolved in downwardly flowing water and insoluble material passes through. The aqueous solution of sulphur dioxide is passed into a surge tank 61 and thence by a pump 63 to the reactor 45 as part of the required stoichiometric excess. The emulsion in the chamber 53 is passed into a coagulation chamber not shown.  Coagulation may be effected by brine/alcohol, brine/acid or solutions of electrolytes or, if desired, the latices may be used as such for coating articles.  In an example 92.3 per cent. of unreacted sulphur dioxide is recovered and reused.

Abstract: 1,092,611. Change-speed control. J. R. SADIER. March 16, 1965 [March 16, 1964], No. 11037/65. Heading F2D. A constant mesh change-speed gear D is preceded by an expanding pulley gear E having a V-belt pulley 18 with a movable flange settable to four different speed settings by a pneumatic or, as shown, an hydraulic servomotor G. The arrangement may be used to drive the spindle C of a machine tool (Fig. 1) having a slide A fast with a cam plate 2 having fingers 3 actuating switches 4 in circuits 5, 8 controlling the expanding pulley gear and the constant-mesh gear. The cam plate may also control other operations of the machine tool. The constantmesh gear has gears 14-16 selectively clutchable to an output shaft 9 by electromagnetic clutches 14a16a, and the expanding pulley is controlled by the servomotor which has a piston fast axially with the movable flange 18a of the pulley 18. A pump 31 supplies liquid through a line 28 to each end of the servo cylinder, and four exhaust lines 33A-33D enter the cylinder at axially spaced locations and have valves 7A-7D controlled by the switches 4 of circuit 5. On one of the valves 7A-7D being opened a pressure differential is created across the servo piston which is thereby shifted until it blocks the opened exhaust line, so that the expanding pulley gear is set to the desired ratio. The rate at which the servo piston shifts is controlled by a regulating valve 38; for rapid shift valve 38 is by-passed by opening a valve 36. The regulated shift movement is used, for example, in machining a radial transverse surface interconnecting two different diameter cylindrical sections of a workpiece which is being machined, the arrangement ensuring that the cutting velocity of the tool is maintained substantially constant. In a modification the servomotor is connected to the movable pulley flange by a lever connected at an intermediate point to the flange and at one end to the servo piston and at its other end is adjustably pivoted to a link which is adjustably pivoted to a fixed frame.
