Title: Fuel and air supply systems of carburetting apparatus
IPC: F02M69/00
Filed: 1945-04-26
Abstract: 590,972. Carburetting-apparatus. BENDIX AVIATION CORPORATION. April 26, 1945, No. 10555. Convention date, Oct. 13, 1944. Addition to 590,960. [Classes 7 (iii) and 7 (vi)] The diaphragm 74 of the fuel-supply valve 80, forming part of the fuel and air supply system described in the parent Specification is subject to the difference between the main air inlet pressure and the pressure near the outlet side of the throttle valve 38: the pressure difference may operate through the spring loading the diaphragm. In the construction shown in Fig. 1, the chamber 78 is connected by a passage 130 containing a constriction 162 and controlled by a valve 136 with the induction pipe on the engine side of the throttle valve 38 and is also connected by a passage 132 containing a restriction 164 with the main air inlet to the carburetter. During idling the suction in the induction pipe transmitted through a passage 146 acts on a diaphragm 138 to open the valve 136 thereby permitting suction to act on the diaphragm 74 and increase the closing force of the valve 80 to reduce the. pressure of fuel supplied to the nozzle 28. As the throttle opens or during acceleration the valve 136 closes and the pressure in the chamber 78 rises to decrease the closing force of the valve 80 and increase the fuel pressure. In Fig. 3, the chamber 78 is open to the atmosphere through a passage 170 and the tension of the spring 112 is adjusted by a plunger 172 engaged by the adjustable end 194 of a rod 190 carried by a diaphragm 188 which divides a casing into two chambers 184, 186. The chainber 186 is subject through a passage 206 to the pressure in the air inlet and the chamber 184 through a passage 204 to the pressure on the engine side of the throttle or to passages opening into the induction pipe on opposite sides of a closed throttle. The pressure of the spring 112 on the head of the plunger 172 is counterbalanced by a spring 178 the tension of which is varied by a bushing 174. In a further modification the rod 190 carried by the diaphragm 188 makes or breaks a switch which controls a circuit including a solenoid which actuates the plunger 172 regulating the pressure of the spring 112.

Abstract: 914,474. Speed-responsive brakes. SCHWERMASCHINENBAU S.M. KIROW VEB. March 27, 1961, No. 11016/61. Class 103 (1). A brake responsive both to overspeeding and excessive acceleration of a winding apparatus, e.g. of a lift, hoist, or crane, comprises a pulley rotated by the winding apparatus and carrying projections 3 which are engageable, according to the direction of rotation, with one or other of two levers 2 pivoted on the axis of the pulley and interconnected by links 5 carrying weights 6, a spring 4 normally maintaining the levers 2 in the positions shown. Shoe members in the form of rollers 8 are carried by links 7 which are pivoted to the ends of the levers 2, the shoe members being guided on blocks 10 secured to the pulley so as normally to be out of contact with the interior surface of a drum 9. Should the speed become excessive, or excessive accelerating torque occur at the running speed, one or both opposed pairs of shoes 8 are moved along the guide blocks 10 and engage the drum with a selfwedging action. The drum 9 comprises a projection 11 engaged between two resilient abutments 12 whereby limited rotation of the drum occurs when the brake is applied, this rotation being used to operate a switch contact (Fig. 2, not shown), for de-energizing the driving motor of the winding mechanism and applying a brake to the lift cage or hoist. Means may also be provided for manually moving the levers 2 relatively to the pulley to keep the device inoperative while the winding mechanism is being run up to speed.

Filed: 1931-01-07
Abstract: 370,887. Manoeuvre signalling apparatus for use on road vehicles. GRAVELEY, H. V. N., 5, Golders Rise, Hendon, London. Jan. 7, 1931, No. 11063/30. [Class 118 (ii).] Coloured manoeuvre signals in a casing at the rear of the vehicle or on one or both sides of the driving mirror are operated automatically or by hand from a switch mounted on the steering wheel and column. The switch comprises three insulated elements A, B, C having ballbearing engagement with one another, the element A being secured to the steering wheel 8, the element C being secured to the steering column whilst the element B normally has an indentation engaging with a spring-pressed peg in the element C but can be rotated through the lead-loaded handle 20. When the steering wheel is moved to the left the spring controlled oontact finger 7 on the element A makes contact with the metallic scroll 6 on the element B to light up the " turn left signals 2R, 2M, the terminals 22, 23 on the element C being connected to the terminals 24 by the switch 21 and the terminals 24 being permanently connected to the contact springs 25. A similar action takes place with the scroll 5 for the " turn right signals. The automatic signalling can be cut out by breaking the switch 21, thus disconnecting the terminals 22, 23 from the terminals 24. When manual operation of the switch is desired the element B is moved by the handle 20 to left or right causing the contact 27 to engage with one or other of the contact springs 25 to actuate the signals. Indentations in the element B engaging with spring-urged pegs in the element C determine the limits of travel of the element B. The signals will remain illuminated until the element B is released by movement of the steering wheel, the finger 7 engaging trips in the element B to release it, the element then returning to its normal position by gravity as shown in Fig. 12. The signalling apparatus can be put into and out of action by the hand brake g operating the switch h, i.

Title: Isochronal governors for power engines
Inventor: BIRO ERNO
IPC: H02P23/00
Filed: 1963-03-20
Abstract: 965, 899. Speed governors. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. March 20, 1963, No. 11098/63. Heading G3B. In a speed governor a driving shaft 1 driven by the engine the speed of which is to be governed, drives a hollow shaft 5 through a gear 3 at a faster rotational speed than a hollow shaft 4 through a gear 2. A number of electromagnets 6, energized by a D.C. source 12 through sliding contacts 7, drive a valve 8 coupled by screw threaded engagement, with a rod 11 axially slidably mounted in the bore of the shaft 4 and connected to the fuel supply, a similar source to the engine driving the shaft 1. Blades 9 provided on the rotor 8 act as an air brake and the braking effect together with the forces of attraction of the magnets 6 are adjusted so that a predetermined slip, equal to the transmission ratios both to the shafts 4 and 5 by the gears 2 and 3, is arranged between the rotor 8 and the magnets 6 and the shaft 11 remains axially stationary. If the engine and hence shaft 1 increase or decrease in speed, the slip between the rotor 8 and the magnets 9 alter and as a result the end of the shaft 11 is screwed into or out of rotor 8 and the shaft 11 is moved axially to effect an increase or decrease in engine speed. The rod 11 may be displaceable between stops and the threaded end of the rod may be split to allow rotation of the rotor 8 about the end of the rod 11 without further axial movement thereof. The voltage to the magnets 6 or the air flow ejected by the blades 9 can be controlled to effect remote control of the governor.

Title: A method of measuring combustion engine crankcase oil consumption
IPC: F16N29/00
Filed: 1968-03-07
Abstract: 1,147,930. Measuring oil consumption. GENERAL MOTORS CORP. March 7, 1968 [March 16, 1967], No. 11112/68. Addition to 1, 095, 056. Heading G1A. In the measurement of the crank-case oil consumption of a combustion engine by the method defined in Specification 1, 095, 056, the tracer is collected from the engine exhaust gases by passing the gases through a mass of porous material containing a reagent with which the tracer reacts so as to be retained by the porous material. This collection process replaces that of the abovementioned Patent in which the exhaust gases are bubbled through sodium hydroxide in an extraction tower. The apparatus is otherwise generally similar to that of the above-mentioned Patent except that exhaust pipes from two inclined banks of cylinders of the engine are connected to respective diverter valves (52), Fig. 1 (not shown) and respective tracer collection devices (58). Each collection device, Fig. 2 (not shown) consists of a canister comprising a steel cylinder, each end of which is covered by a stainless steel mesh, and containing molecular sieve pellets of sodium aluminium silicate. Before the measurement operation, the two canisters are dipped in a 2-molar solution of sodium hydroxide which is retained in the pores of the sieve and then inserted in the exhaust lines. The exhaust gases are then passed simultaneously through the canisters for a predetermined time. The canisters are removed and the activity of each measured by a scintillation detector comprising two sodium iodide crystals electronically coupled to a common scaler. The measured activity is proportional to the oil consumption, a formula for the calculation of which is given. The canisters may be rendered reusable by soaking in water to remove the sodium bromide formed by reaction of the bromide tracer compound with the sodium hydroxide. Instead of the use of a canister filled with porous pellets, a container carrying a filter paper treated with reagent, may be used. This is crumpled up for fitting into the scintillation detector.

Filed: 1946-04-11
Abstract: 615,251. Clutches. LANGDON, A. G. April 11, 1946, No. 11156. [Class 80 (ii)] Controlling mechanism for a friction plate clutch comprises a control disc 2 formed with circumferentially spaced openings for accommodating balls or rollers 4 which project each side of the disc and coact with grooves in control plates 1, 3. The control disc 2 may be splined to a sleeve 11 secured to a driving shaft 12, or it may be rotatably mounted on the shaft and one of the control plates 3 provided with peripheral serrations which engage the outer case of the clutch. On initial engagement of the clutch, rotation of the control plates 3 relative to the disc 2 causes the balls 4 to ride up the inclined surfaces of the grooves, forcing the plates 3 further apart and preventing further slip between clutch plates 6. The heads of screws 8 in the disc 2 engage recesses 9 in the plates 3 and limit the outward movement of the latter.
