Abstract: 385,373. Charging aircraft engines. AVIONS H. M. D. FARMAN, 167, Rue de Silly, Billancourt, Seine, France. Sept. 30, 1931, No. 27207. Convention date, Sept. 30, 1930. [Classes 7 (ii), 7 (iii), and 7 (v).] A carburetter 35 is provided with a branched air inlet leading to the atmosphere through the pipe 148 and to a blower 51 through the pipe 141 and cooler 142. The outlet from the carburetter is connected to a second blower 34, which is permanently driven off the crank shaft through multiplying gearing 15, 23, 24, 26. The blower 51 is used only when the aircraft is at high altitudes being optionally driven from the crank shaft ; the air admission to this blower is varied by a throttle 151 either hand or barometrically controlled. A flap 147 moves automatically to open or close one or other air pipes to the carburetter according as the blower 51 is working or not. The blowers, carburetter and mounting for an engine turning gear 46 are mounted as a unit on an extension 14 to the crank case. Clutches ; pump driving-gear.-The blower 51 is driven off the wheel 15 on the crank shaft extension through the lay shaft 18, wheels 71, 73, spindle 74, friction clutch 85, wheel 97, two wheels 116, 116a, Fig. 3, friction couplings 125, 125a whose rims carry toothed wheels both driving the pinion 134 on the blower spindle 135. The friction clutch is closed centrifugally by levers 105 carrying the weights 107 ; the levers have lugs which act on pins 113 mounted on the axially-movable ring 101, which has internal teeth keying it to the driving disc of the clutch. The ring and the driven disc 95 carry friction surfaces 102, 98a, between which is mounted a disc 78. Springs 108 acting on the levers tend to maintain the friction surfaces in contact with the disc 78. The clutch is held open by a hand-actuated muff 97 ; when this is moved to the position shown, the weights 107 acting on the levers 105 are free to close the clutch and thereby drive the blower 51, shock at the commencement of drive being taken up by the friction couplings 125, 125a. Turning-gear.-The starter 46 works through the clutch 52, 53, bevel gearing 58, 62 and an engaging member 69 on the lay shaft 18 for the blower 57, which shaft is geared to the crank shaft 10 by the wheels 17, 15.

IPC: B21D43/02
Filed: 1956-09-06
Abstract: 810,060. Metal working presses; machine-tool details. PRESS EQUIPMENT Ltd. Aug. 30, 1957 [Sept. 6, 1956], No. 27279/56. Classes 83 (3) and 83 (4). A power - driven feed - mechanism for feeding components to a powerpress or the like has a member 12 movable through a predetermined distance whilst a component is being inserted in the press, and which is arranged to interrupt the feed if it is not moved through its normal distance during insertion of the component. The feed-mechanism is of the kind described in Specifications 780,203 and 733,347 and is driven by an electric - motor 61 through a clutch 62 and gear-box 57, and includes an arm 40 oscillating horizontally about a vertical pivot 41, Fig. 5 (not shown), between extreme end-positions, i.e. a component pick-up position and a component insertion position. At these positions a platform 10 carrying the arm is rocked about a horizontal pivot, respectively to raise and lower the components. Platform 10 is connected by link 12 to a lever 18 pivoted at 17 and connected at 19 to a vertically-adjustable spindle 21 pivoted at 23 to a curved arm 24. The left-hand end of this arm has a lip 28 cooperating with a cam-projection 29 on a disc 27 secured to the output shaft of the gear-box; the right-hand end is connected to a clutch trip-rod 77. During each manual feed the lip 28 is raised out of the path of the cam 29, but if the feed-movement is less than normal due, e.g. to two components being inserted together, the lip is engaged by the cam, which moves the arm 24 to trip the rod 77 and cause it to release the clutch-engagement lever 65 as described in Specification 780,203, thereby to disengage the feed-mechanism and apply a brake. The press is also stopped. Alternatively the lever 24 may operate a switch which stops the motor 61.

Title: Combustion methods and apparatus
Inventor: SHERMAN RALLSTON MARIGOLD
IPC: F23M9/06
Filed: 1961-07-27
Abstract: 981,087. Fluent fuel combustion chambers; burning refuse. SILENT GLOW OIL BURNER CORPORATION. July 27, 1961, No. 27314/61. Heading F4B. Liquid, gaseous or pulverulent  fuel mixed with air is projected along a trough at the bottom of a combustion chamber, and the resulting flame and combustion products are deflected upwards to circulate round the combustion chamber to become entrained in the flame, a combustion products outlet passage leading from the bottom of the trough at a point spaced from the burner. In one embodiment, the trough, deflecting baffle and flue outlet are formed in a block of refractory material, Fig. 1, not shown. In a modification, Figs. 4 and 5, a trough is formed from metal side walls with vertical lower parts 87 and outwardly flaring upper parts 85, connected to a plate 73 closing the top of the space surrounding the trough. A baffle-plate 83 extends upwardly and rearwardly from a plate 89 connecting the ends of the vertical wall parts 87. A flue duct 94 extends from an opening in the plate 89 to the flue 95. A bar 39 of refractory material supported by the side walls of the combustion chamber at right-angles to the trough forms a baffle to guide the combustion products round the chamber. Auxiliary fuel may be fed to the stream of gases from a burner 101, or a burner 101A, or oil fuel may be dripped from the burner 101A on to the top of the baffle bar 39. When an auxiliary fuel is used, secondary air from an inlet 105 is fed to the casing surrounding the trough to issue from holes 107 in the top-plate 73. The primary fuel supply to nozzle 65 may be cut off when the trough walls are sufficiently hot for combustion of the auxiliary fuel to continue alone. A thermocouple 108 arranged in the flue outlet 94 cuts off the primary fuel supply and restores it according to the temperature of the flue wall which will provide a measure of the temperature of the trough. The secondary air supply is cut off when the primary fuel is cut off. In another embodiment, Figs. 12 and 13, a trough of triangular vertical section is formed from metal sheets 175 connected to a top wall 181 within a cylindrical casing. The ends of the trough are closed by a wall 171 through which the burner 65 and air inlet sleeve 205 extend, and a wall 173 connected to a triangular flue duct 199. A plate 187 above the outlet to duct 199 forms the deflector baffle. An upper combustion chamber fits on to the top of the lower casing, and has a dependent cage 239 for solid fuel or refuse, which is burnt with the aid of the primary flame and secondary air passing through holes in the air supply sleeve 205 to the space surrounding the trough and holes 210 in the top plate 181 to the upper combustion chamber. The supply of primary fuel and of secondary air can be cut off or reduced under the control of a thermocouple in the flue passage, which may lead direct to a dust separator.

Title: Improvements in and relating to protective devices for electric apparatus
IPC: H02H3/28
Filed: 1919-11-06
Abstract: 158,640. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 6, 1919. Electromagnetic switches; protective arrangements. - The relay of a protective system for parallel conductors consists of a contact-carrying member pivoted at each end to the core of a solenoid, and at its middle point to the core of a third solenoid. When the current conditions in the parallel conductors are balanced, the extreme solenoids are energized to hold the contact-carrying member in its inoperative position; but upon an unbalancing of the current conditions, the central -solenoid is energized to overcome the action of the weakened solenoid, and a tripping circuit is closed to open the conductor having the greater current. When applied to three-phase circuits, the solenoids are connected across similar phases, and when applied to three or more conductors, two of them are grouped. The member 1, Figs. 1 and 3, carrying the contact 2 is pivoted to the cores 5, 6 of solenoids 7, 8 and to a rod 16 operated by the core 13 of a solenoid 14. The cores 5, 6 are provided with collars 9, 10 which engage non- magnetic stops 11, 12 when the solenoids 7, 8 are normally energized, thereby holding the contact 2 in its mid-position. The solenoids 7, 8 are connected in series with the secondary windings 26, 27 of current transformers in the conductors 21, 22 and the solenoid 14 is connected across the secondaries of the transformers. If a fault occurs in the conductor 22, the current through the solenoid 7 is increased and the solenoid 14 is energized. The solenoid 14 overpowers the solenoid 8 and the member 1 is moved about its pivot on the core 5, thereby causing the contact 2 to bridge the contacts 3 to close the tripping-circuit of the switch 25 in the circuit of the conductor 22. The contact 2 bridges contacts 4 when a fault occurs in the conductor 21.
