Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M19/02
Filed: 1943-09-10
Abstract: 567,136. Spray carburetters. AERO ENGINES, Ltd., and HALLIDAY, G. F. Sept. 10, 1943, No. 14911. [Class 7 (iii)] In a carburetter of the kind having a tubular stem projecting into the induction passage at the inlet side of a butterfly throttle valve which, in its closed position, isolates the bore of the stem from the inlet portion of the induction passage, the stem conveying fuel-air mixture to the passage, the valve member is formed with an aperture which registers with the bore of the stem when the valve is closed and places the bore in direct communication with the induction passage behind the throttle valve. Fuel from a float chamber 22, Fig. 2, flows through a passage 28 to a nozzle member 24 having at its lower end a calibrated passage 30 leading to a well 31 into which dips a needle valve 72. The needle is urged downwards by a spring 65 which presses a plunger 64 rigid with the needle against cams 40 formed on the inner face of a butterfly valve 41 controlling the main passage 12, 11 of the carburetter, movement of the butterfly valve thus actuating the needle valve. In its closed position, the valve 41 seats closely on the oblique top of a tubular stem 33 which surrounds with clearance the needle 72 and nozzle 24, providing a passage for air fed to it through a channel 74 opening out of the main air inlet 12 and the fuel air mixture thus formed passes through an aperture 68 in the butterfly valve 41 to the induction passage 11. The spindle 42 of the valve 41 is rigidly secured to an arm 46, Fig. 3, engaged at its outer end by a Bowden control mechanism 49. A rod 53 extending through an aperture in the arm 46 engages the arm by a head 54 and may be lifted by a cam device 59, 60 to set the lever in position for starting, as shown, or for slow running by turning a knurled knob 58 through a quarter turn. The sleeve 55 carrying the cam device is adjustable. In a modification, the needle valve is replaced by a simple calibrated orifice.

Title: Control System for Vehicles having Steering Clutches and Brakes
IPC: B62D11/08
Filed: 1968-03-28
Abstract: 1,170,034. Controlling steering brakes and clutches. KOMATSU SEISAKUSHO K.K. 28 March, 1968 [29 March, 1967], No. 14936/68. Heading B7H. [Also in Division F2] In a vehicle control system comprising left- and right-hand control pedals coupled to steering clutches and brakes through control means which release the appropriate clutch upon initial depression of a pedal and then apply the brake upon further depression of the pedal, the control means are such that when both pedals are depressed either simultaneously or one subsequently to the other then both brakes are applied with both clutches engaged. The pedals 1, 2 are secured to torque shafts 1a, 2a each carrying two levers linked respectively to brake levers 7, 8 by rods 3, 4 and to levers 14, 15 on a clutch control valve assembly 16 by rods 11, 12 including overstroke springs 13 which accommodate the continued movement of a pedal necessary to apply the brake after initial movement of the pedal has actuated the valve assembly 16. The clutch control valve assembly 16 comprises two spring-loaded sliding spools 21, 22 each actuated by one of the levers 14, 15. When neither pedal 1, 2 is depressed both spools 21, 22 occupy a position wherein pressurized fluid flows from an inlet chamber 25 across grooves in the spools to respective ports 26, 27 connected to the clutches which are thereby held engaged. When one pedal 1, 2 only is depressed one port 26 or 27 is cut off from the inlet chamber 25 by a land 40 on the displaced spool 21 and is placed in communication through a chamber 28 and across a groove in the other spool 22 with a drain port 43 so that the appropriate clutch is disengaged. When both pedals 1, 2 are depressed and both spools 21, 22 displaced, the lands 40, 40a prevent direct communication between both ports 26, 27 and the inlet chamber 25, but both are supplied therefrom through by-pass passages 29, 30 and the clutches remain engaged, further lands on the spools 21, 22 blocking communication of either port 26, 27 with the drain port 43. The spools 21, 22 are so arranged that during simultaneous depression of both pedals 1, 2 the clutches are disengaged at no stage of pedal travel. The overstroke springs 13 may be omitted, there being employed a modified control valve assembly (Fig. 8, not shown) arranged to accommodate greater spool displacement. The pedals 1, 2 may have mutually interposed parts 51, 52 (Fig. 6a) at their adjacent ends for facilitating simultaneous depression of both pedals with a single foot, and/or guard structures 55, 56 (Fig. 7) may be fitted beneath the pedals to prevent a foot depressing and releasing one pedal from being trapped beneath the other.

Title: Improvements in or relating to Extrusion Presses as used for the Manufacture of Tubes and Hollow Sections.
Inventor: JACOBSEN OLAF BERG
IPC: B21C25/04
Filed: 1917-10-16
Abstract: 118,925. Jacobsen, O. B. Oct. 16, 1917. Squirting. - In an extrusion press for forming metal tubes or hollow sections from heated hollow billets, the tubes are formed by passage of the metal between a die band a mandrel c which is attached to a thrust member d attached to a ram e. The metal is extruded from a container which is held against the die b by an hydraulic ram and can be moved away therefrom, when desired, by a separate ram. The extrusion pad n, is advanced to form the tube by the combined action of the thrust member d and a sleeve f, which advances with it, a ring o being inserted between the sleeve f and pad n. When the tube is nearly formed, the container a is withdrawn from the die b, and the sleeve f is advanced relatively to the member d by means of auxiliary rams which advance a cross-head g relatively to the main ram e, and the extrusion process is thus completed. The member d is then withdrawn by a separate ram, thus stripping the tube from the mandrel, and the cross-head g and sleeve f are withdrawn subsequently to assume the relative position to the member d shown in Fig. 2. The mandrel c is received by a guiding-nipple b<1>, and a slide for removing the finished article works in a recess j. The auxiliary ram cylinders for operating the cross-head g may be fitted with flexible conduits and be carried by the main ram, and they serve only to advance the sleeve f relatively to the member d during the completion of the extrusion.

[Also in Groups XXVII and XXXIV] In a vehicle braking system wherein the braking is effected by the closing of the exhaust outlet of the engine and by fluid pressure operated braking system, a fluid pressure actuated braking mechanism is provided with a driver-operated control valve together with a fluid pressure operated device which controls the closure of the exhaust, the supply of fluid under pressure thereto being controlled by an electro-magnetically operated valve with an electrically controlled device for cutting off the fuel to the engine, the energizing circuit of the electro-magnetically operated valve and of the electrically controlled device being controlled by a switch arranged to be operated in response to the initial movement of the driver's control valve to effect the application of the fluid pressure braking mechanism. In the embodiment illustrated in Fig. 1, the compressed air brake cylinder 1 is supplied with compressed air from supply pipe 2 through driver's foot valve 3 and pipe 4. The engine exhaust is closed by a compressed air operated cylinder 5 the supply of compressed air to which and its release therefrom being controlled by an electro-magnetically actuated valve 6. An electrically actuated device, the energizing winding of which is illustrated at 8, when energized, also cuts off the supply of fuel to the engine of the vehicle. When pedal 17 is depressed to brake the vehicle through control valve 3 in the usual manner, the switch 16 is closed and the winding 15 of the relay 10 is energized to close contact 9 and effect the supply of current to windings 7 and 8. The energizing of winding 8 causes the supply of fuel to the engine to be cut off and energization of the winding 7 from the position shown to operate valve 6 to supply compressed air, via inlet 14, to the cylinder 5 and to cause closure of engine exhaust. A stop lamp 18 connected in parallel with winding 15 may be provided. Switch contacts 11 are arranged to be closed only so long as the engine of the vehicle is rotating at above predetermined low speed to prevent exhaust braking when engine is running at idling speed. An alternative braking system is shown in Fig. 2 wherein the switch 16 is replaced by a pneumatically operated switch device 20 supplied with compressed air from pipe 4 when the pedal 17 is depressed.
