Title: Fluid power steering system
Inventor: MORENO EMIL FRANK
IPC: B62D5/09
Filed: 1965-04-08
Abstract: 1,098,123. Power steering; beam axle suspensions. INTERNATIONAL HARVESTER CO. April 8, 1965, No. 14910/65. Headings B7D and B7H. A vehicle power steering system has a control valve 40 supplied with pressure fluid by a primary pump 42 on relatively slow steering wheel movements and by the pump 42 together with a secondary pump 43 on relatively faster steering wheel movements. The invention is shown applied to a dump truck 10 with driven front and rear axles each of which is located by pairs of parallel links 16 on each side, is suspended by leaf springs and hydraulic shock absorbers 17 and carries dual wheels 18 at each end. Each stub axle 22 of the steerable front axle is carried by an axle portion 21 through two vertically-spaced part-spherical bearings 26 (Fig. 4, not shown). Power steering system.-In the neutral position the outputs from the pumps 42 and 43 pass respectively through passages 83, 84, 96 and a check valve 99 and through passages 86, 87 of the control valve to an outlet 50 and a reservoir 44. Also the lines 100/102 and 101/103 to the hydraulic actuators 31 are blocked by load valves 45 to prevent wheel shimmy. When the steering wheel 141 is rotated slowly clockwise the pump 143, which is connected to chambers 92 at each end of the control valve, displaces the valve spool to the left and the output from the pump 42 passes through passages 83, 82, an outlet 97 and lines 100, 102 to the actuators 31 to turn the wheels. The exhaust from the actuators returns to the reservoir through a line 103, the valve 45, which has been opened by the increased pressure in the line 108 communicated to a chamber 112 of the valve 45, the line 101, the passages 98, 64 and 85 and the check valve 99 of the control valve 40. On faster movement of the steering wheel the valve spool 55 is displaced further until the land 61 abuts a bore 78, the output from the pump 43 then pushing an unloading valve 123 to the left and combining with the output of the pump 42 to steer the wheels more quickly. Feel is provided by the valve spool centring springs 67 and by a servopump 154 pivotally interconnecting one axle portion 21 and one stub axle 22 and containing a piston which on steering movements displaces hydraulic fluid through lines 170 and 171 from one side to the other of the manual pump 143 tending to centralize the valve spool and resist steering wheel movement. If in the neutral position one wheel hits an obstruction sufficient to open the valves 45 and turn the wheel the servopump 154 displaces the valve spool 55 to restore the wheel. The valve spool neutral position is adjusted by nuts on slidable pins 70 the heads of which abut within the ends of the spool 55.

IPC: H02K7/065
Filed: 1916-10-20
Abstract: 110,569. Oulianine, S. Oct. 20, 1916. Electro-magnetic switches; contacts.-In a harmonic relay the armature is caused to produce by means of a pawl and ratchet the rotary movement of a shaft upon which is muunted resiliently a braked member carrying a contact adapted to close the controlled circuit. In the arrangement shown in Figs. 1 and 2 the windings 1 are energized by pulsating current of predetermined frequency and its armature 1<1> is mounted on a spring 2 or upon cords fixed at points a, b. The armature 1<1> carries a pawl 3 engaging a ratchet wheel 4 mounted on a shaft 5 which also carries an insulated metal drum 10 and a loosely mounted fly 6, resiliently connected to the shaft 5 by means of a spring 7. The fly carries a spring 8<1>, one end 8 of which normally rests on an insulating portion 11 of the drum 10, while the other end 9 bears against the shaft 5 which is connected to a battery circuit 13. A contact 12 engages the conducting portion of the drum 10. When the shaft 5 is rotated by the successive energizations of the windings 1, the fly 6 lags behind the shaft 5, thereby causing the end 8<1> to leavel the insulating portion 11 of the drum and complete the circuit 13. The member carrying the spring 8<1> may be braked magnetically.

Title: Improvements in or relating to the stopping of internal combustion engines
IPC: F01L13/00
Filed: 1933-05-24
Abstract: 420,599. Stopping. GRIEVE, E. J., and RUSTON & HORNSBY, Ltd., Sheaf Iron Works, Waterside South, Lincoln. May 24, 1933, No. 14980. [Class 7 (v)] To facilitate the stopping of a four-stroke compression-ignition or other engine upon cutting off the fuel supply, an outwardly opening spring - closed compression - relief valve is positively locked or held closed during normal running, and the locking or holding means is released during the stopping period, so that air drawn into the cylinder during the suction stroke is compressed until its pressure overcomes that of the relief valve spring, and is then expelled during the remainder of the compression stroke, while a partial vacuum is formed during the following outstroke until the exhaust valve is opened. As shown, the relief valve a closes a passage c in the head d of each cylinder, which provides communication between the combustion chamber e and passages r in the valve casing b. The valve is closed by a spring f which is sufficiently strong to allow the valve to open on the compression stroke when a predetermined compression has been reached. During normal running, the valve is prevented from opening by a stronger spring g, Fig. 2, acting through a slidable bar i and a cranked lever j pivoted to the bar i and to a lug k on a cap closing one end of the valve casing b. The lever j carries an adjustable set-screw s bearing against the valve stem. For releasing the valve a, the end of the bar i is jointed to a bell-crank lever l pivoted upon a fixed plate m supporting a shaft o carrying at one end a hand-wheel or lever for controlling the stopping, starting, and reversing of the engine. On turning the hand-wheel to the stopping position, a cam p on the shaft o actuates the lever l to slide the bar i to the left in Fig. 2, moving the levers away from the valve spindles. The valves are then free to open on the compression stroke when a predetermined compression has been reached. The Provisional Specification states also that stopping may be facilitated by throttling the inlet and outlet of air throughout all four strokes of each cycle, the normal inlet and exhaust valves being held closed.

Title: Improvements in or relating to automatic electric follow-up switching mechanism
IPC: G05D3/12
Filed: 1946-05-17
Abstract: 629,650. Control of motors. AMALGAMATED WIRELESS (AUSTRALASIA), Ltd. May 17, 1946. No. 15068. Convention date, May 18, 1945. [Class 38(iii)] [Also in Group XXXVIII] A follow-up switch which automatically moves by the shortest path to its selected position is driven by a two-field reversible motor 4 imparting intermittent motion. to the switch shaft 5 through a worm gear 7, 8 and Geneva-stop-mechanism 10, 14, Fig. 2, which is locked in the stop-position corresponding to the selected switch position by an arcuate projection 15 on the pinwheel 10 engaging one of the corresponding recesses 13A in the star wheel 14. The motor is energized over a remote pre-selector switch 9 connected to corresponding stationary coarse control contacts I-X arranged round an insulated disc 48 on the shaft 5 to engage sectors 27, 28 connected through slip-rings 21. 22 and brushes 26, 23 to the counter-clockwise and clockwise motor fields, respectively. Starting from the position shown when the switch reaches the pre-selected position, say III, and the locking segment 15 starts to enter the recess 13A, a pin 25 on the disc 48 travels under contact III and raises it from sector 27 to engage the ring 16 whereby the circuit is changed over to the cam-operated fine control switch, through selector arm 19 moved by frictional engagement with the shaft 5, between two contact pins 17, 18. In the conditions in question the arm 19 is in engagement with contact 18 whereby the. counter-clockwise field circuit is maintained through ring 16, flex 32, pin 18 and contacts 31c, 31d of the fine control switch until.positioning is completed, when the cam 24 lifts the bridge 29 and opens the circuit. Owing to the inertia of the armature the continued fovement of the cam 24 causes the bridge 29 'to close contacts 31a, 31b to energize the clockwise field and bring the motor to rest, the bridge 29 being again in neutral position. Since the five contacts either side of the contact III will be connected through sectors 27, 28 to the clockwise and counter-clockwise fields respectively the switch will take the shortest path to the next selected position and the arm 19 will select either contacts 30 or 31 of the fine control switch to apply the correct postioning and braking fields.

Title: Improvements in and relating to regulating systems for alternating current circuits
IPC: G05F1/32
Filed: 1919-06-16
Abstract: 140,285. British Thomson - Houston Co., (General Electric Co.). June 16, 1919. Regulation, automatic systems for.-In alternating-current distribution systems, the voltage is automatically regulated by providing two alternative paths for the current through separate tappings on a transformer, and arranging means whereby the reactance of the separate paths is varied with varying voltage in the tapped-off circuit. In one arrangement. Fig. 1, an autotransformer 5 having two separate tappings 11. 12 feeds the secondary circuit S the voltage of which is to be regulated. Connexions from points 11, 12 constitute alternative paths, which have a common return to a terminal 6. Devices 13, 14 for imposing variable reactances on the corresponding circuits are connected in the manner shown. Each device consists of two double-limbed magnetizable cores, one limb wound with coils in series with the corresponding tapping, and the other limb wound with magnetizing-coils connected in one of a pair of circuits branching from a pair of auxiliary bus-bars 33, 34. These busbars are fed by a direct-current generator, or by an alternating-current generator of lower frequency than the circuit to be regualted. The object of the auxiliary bus-bars and the magnetizing-coils energized therefrom is to impress magnetic fluxes upon the reactor devices 13, 14 in such a manner that the choking effect upon the circuits associated with the respective tappings 11, 12 is decreased or increased, and thereby to determine, automatically which of the tappings shall have the preponderating effect in energizing the circuit 8. For this purpose, two similar dynamo-electric machines 27, 28 mechanically coupled together have their armatures connected in the respective magnetizing-circuits, and their field windings 31, 32 in a loop across the busbars 33, 34. A potential relay 36, in responding to rise or fall of voltage in the circuit 8, is adapted to short-circuit one or other of the field windings at one or other of the contacts 43, 44. The particular machine of which the field is not short-circuited runs as a motor and produces a counter-electromotive force in the corresponding magnetizing-circuit, whereas the other machine is electrically dead, and the electromotive force in the corresponding magnetizing-circuit is increased. The effective reactance in the circuits from the tappings 11, 12 is thus increased in one part and diminished in the other, and the effective voltage applied to the circuit 8 thus approximates either to the voltage tapped off at point 11 or to that tapped off at point 12. Under ordinary conditions of regulation, the potential relay 36 is in a state of rapid vibration. The reaction devices may have the modified form shown in Fig. 2, which shows a four-limbed core 46 wound with two choking-coils 49, 50 in parallel or separate limbs and one magnetizing-coil 51 wound round both the inner limbs. Resistances may be connected in series with the choking-coils for the purpose of augmenting the speed of the regulator.
