Filed: 1930-12-29
Abstract: 376,227. Current and pressure meters ; power meters. BE•R, F., 6, WesselÚnyi u, Budapest. Dec. 29, 1930, No. 39113. Convention date, Dec. 27, 1929. Void [Published under Sect. 91 of the Acts]. [Class 37.] An arrangement for compensating for pressure drop in the leads to electric measuring instruments comprises the provision of one or more auxiliary measuring instruments B measuring the drop in the leads 1-5, 2-4 and connected mechanically to the main instrument pointer so as to add the drop thereto. The sensitivity of the instrument B may be the same as that of the main instrument A and when one auxiliary instrument B is used its sensitivity is double that of the main instrument and the resistances of both main voltmeter leads are equal. The sensitivity of the instruments B may be adjusted by inserting resistances 4, 4<1>, Fig. 3, in the lead 2, 4 so that the potential added by it to the reading of the main instrument A, being double that in the line 2, 4, has a greater effect thereon. The Specification includes a mathematical discussion and gives optimum values for the resistances of the main and auxiliary instrument leads. The Specification describes adaptations to potentiometric and semipotentiometric measurements as used in measuring the e.m.f. of a thermo-couple or a tach meter dynamo, to measurement of true current, voltage and power delivered to a consumer and to compensation of wattmeters &c. for pressure drop. Methods of adjusting the instruments to the correct values of sensitivity are also given. The auxiliary instruments may be integral with or separate from the main instruments and may or may not be of the same design.

Title: Improvements in or relating to electric control mechanism
IPC: H01H3/58
Filed: 1956-12-27
Abstract: 806,766. Controllers; time switches. BORGWARNER CORPORATION. Dec. 27, 1956 [Dec. 29, 1955], No. 39297/56. Addition to 710,541. Classes 38 (3) and 38 (5). Relates to a controller as described in the parent Specification in which an electrical contact carrier C is driven in a rectilinear direction by means of screw 18, a slide 11 being provided for coupling or uncoupling the screw and carriage. Means are now provided for positively locking the slide into engagement with the screw. Such means comprise a backing-plate 27, which is mounted upon the slide, and a locking device 28 formed of resilient material. By virtue of the disposition of the lock between the backing-plate and cam 24, motion of the slide upwardly is prevented unless rod 14 is withdrawn to the left. Thus, during rotation of the screw, while the slide is engaged therewith, any tendency for the lugs 16, 17 to become disengaged from the screw, is avoided by means of the lock. When the operating rod 14 is pushed inwardly the lugs 16, 17 do not immediately engage a groove in the screw 18, and, during this interval, the cam 24 abuts the lock 28. Due to the resiliency of the lock, it is pushed outwardly by the end of the cam. As soon as the lugs engage a groove in the lead-screw, the lock slides off the end of the cam and snaps inwardly between the cam and the backing-plate.

Title: Improvements relating to control valve devices for vehicle fluid springs
IPC: B60G17/052
Filed: 1958-12-08
Abstract: 867,392. Railway vehicle undercarriages. WESTINGHOUSE AIR BRAKE CO. Dec. 8, 1958 [Dec. 16, 1957], No. 39460/58. Class 103(6). In a railway vehicle, a bolster 3 Fig. 1, is supported by an air spring 2 from an unsprung side frame 4 and a control valve device 1 secured to the bolster and pivotally connected by a linkage 7, 8 to the side frame 4, is connected by pipes 9, 11, with an air reservoir 10 and the spring 2, respectively, whereby the bolster is maintained a preselected height relative to the side frame irrespective of the load carried by the vehicle. As shown in Fig. 2, the control valve device comprises a casing 12 having an exhaust chamber 20 and piston valve 13 slidable in a bush 15 in a bore 16, the valve being urgeable in either direction by a spring 23. The piston has a plugged bore 17 connected by radial passages to annular cavities 18, 19 and the latter are registerable with radial passages in the bush, when the piston is moved to the left, to connect the air supply pipe 9 through a choke 57 with the pipe 11. The piston also has a reduced portion 54 whereby when the piston is moved to the right the pipe 11 is connected to the chamber 20 so that air is exhausted from the spring and finally to atmosphere through ports 55 and a vent valve 56, and at the same time the air supply pipe 9 is closed. The piston valve 13 is operable by a T-shaped cam member 39 having one arm 40 engageable in a slot 21 in the piston. The member 39 is rockable on a pin 43 by means of a cam actuated lever 29 secured to a rotatable shaft '5, in turn secured to the lever 7 of the linkage connected to the side frame 4. The actuator 29 has a roller 33 normally disposed within but not in contact with a semicircular recess 51, of the member 39, which is joined at each end by small radii curves 49, 50, with circular cam surfaces 47, 48 respectively. When the load on the vehicle increases the arm 29 is rotated clockwise to cause the cam member 39 to rotate anticlockwise and move the piston to the left, whereby air is supplied to the spring until such time as the bolster again rises and returns the parts to the position shown. Similarly if the load decreases the piston will be moved to the right and connect the spring to exhaust, until such time as the bolster again descends. The lost motion clearance between the roller 33 and the surfaces 49, 50 ensures that the piston valve will not be operated as the bolster oscillates within normal limits, due to bouncing. Specification 813,150 is referred to.

Title: Apparatus for and method of controlling air-fuel mixture in a carburetor of an automotive internal combustion engine
IPC: F02M7/11
Filed: 1974-09-13
Abstract: 1478172 Automatic control of fuel supply to IC engines NISSAN MOTOR CO Ltd 13 Sept 1974 [19 Sept 1973] 39996/74 Heading G3N [Also in Division F1] The fuel supplied to an I.C. engine by a carburetter is modified by providing a pressurized air supply whose flow-rate is controlled by the actuation of a flow control valve 48 and directed by a flow shift valve 50 to apply pressure either to the body of the fuel or to the discharge passages of the carburetter. The valves are controlled by an electrical control unit 52 which responds to engine operating conditions to supply a pulse train signal to valve 48 and a steady signal to valve 50. In operation the valve 48 will supply pressurized air, at a rate determined by the mark/space ratio of the pulse train on line 140, to the shift valve 50 which in the position shown directs this air to the carburetter float chamber to increase the flow of fuel. The valve 50 is kept in the position shown whenever an engine operation condition is detected by discriminator 142 as leading to operation with an over-weak mixture. If the engine operation detected normally has an over-rich mixture then valve 50 is energized and diverts the airflow into the main fuel discharge tube 38 and to the idling discharge tubes 40, 42 which both reduces the fuel flow and provides better mixing. In the arrangement shown the inlet air flowrate is derived from measurements of the engine speed Sn and inlet manifold vacuum and the function generator 134 produces a corresponding voltage V which is added to a constant sawtooth waveform Vt to produce a sawtooth voltage which is applied to a combined comparator and pulse generator to give an output pulse train whose mark/space ratio is determined by the constant level voltage Vr and thus varies with the voltage V. If the air-flow-rate detected by disciminator 142 is low, a weak air/fuel situation, there is no output signal on line 144 and valve 50 remains in the position shown. If however the air-flow is such that an over rich mixture would be produced then a signal on line 144 causes valve 50 to operate and connect the air supply at port 88 to the outlet port 92. A capacitor 146 may be used to smooth the movement of the shift valve. The control may also respond to engine temperature, acceleration and deceleration, starting and idling conditions, altitude, exhaust temperature or composition by supplying a measurement of the respective variable as an input S D  to the control unit. The arrangement may also be used with variable area carburetters.

Abstract: 1,235,855. Blind riveting. GEORGE TUCKER EYELET CO. Ltd. 5 Sept., 1968 [6 Sept., 1967], No. 40657/67. Heading B3U. A blind riveting tool comprises a closed ended sleeve 52 arranged to advance by means of a piston-rod 40 into a reservoir chamber 24 containing hydraulic fluid to cause fluid under pressure to flow into a cylinder 110 to actuate a piston 112 whereby a pull is imparted to the mandrel, the sudden release of pressure when the mandrel breaks resulting in advance of the sleeve 52 relative to the rod 40. The piston 112 carrying sealing rings 114, 118, is mounted for transverse movement on a piston-rod 120 and bears against a flange 124 thereof by a spring clip 128 engaging a washer. In operation, a plunger 84 is depressed by a trigger 94 to open a valve 68 by dislodging a ball 76 from a seating ring 78. Compressed air from a hose fixed to a tubular coupling 74 is thereby passed through an insert 70, port 66 and into a chamber 22 to raise a piston 34 carrying the rod 40 and sleeve 52. Hydraulic fluid is forced from the reservoir 24 through a port 170 to move the piston 112 rearwardly together with its piston-rod 120 and attached jaw housing 154 causing jaws 160 to be cammed forwardly to grip and then pull the mandrel until it breaks. When the mandrel breaks, the sleeve 52 is advanced relative to the piston-rod 40 to avoid drag on and the transmission of shock to the piston 34. When the trigger 94 is released, the valve 68 is closed and the fluid in front of the piston 112 is forced back into the reservoir 24 to cause the sleeve 52 to retract which in turn retracts the piston 34, the air being exhausted to atmosphere through the top of the insert 70. The piston 112 is returned to its initial position by springs 178, 180.
