Title: Improvements in variable speed transmissions
Inventor: ALSCH RICHARD EMANUEL
IPC: F16H15/52
Filed: 1966-12-31
Abstract: 1,124,670. Variable-speed friction planetary gear. GRAHAM TRANSMISSIONS Inc. 31 Dec., 1966, No. 58491/66. Heading F2D. In an infinitely variable friction gear comprising inclined planetary conical rollers 26 urged centrifugally outwardly into rolling frictional engagement inside a non-rotatable control ring 28 adjusted axially at 32, 34 to vary the speed ratio, the rollers are formed with spherical friction ends 52 engaging an output annulus 54, or sun, fast with an output shaft 60, each roller being supported at 24 in split bearing blocks 22 mounted in radial slots of a spider (Fig. 2, not shown), fast with an input shaft 14, 16, permitting outward movement of the rollers about the centre of the spherical ends 52. The ball ends 52 are thrust into rolling engagement in the annulus race 54 by an inner race 64 spring loaded by a Belleville spring 66 acting through a thrust bearing 68, the spring force being strong enough to prevent slip between the balls 52 and races 54, 64 when a stalling load is applied to the output shaft, whereby the slip will occur between the rollers 26 and control ring 28. The curvature of the races 54, 64 is slightly greater than the ball ends 52 to achieve line contact (Fig. 3, not shown). The rollers 26 are additionally preloaded outwardly by a pair of tapered loading rings 38, 42 spring loaded towards each other to bias the rollers into contact with the control ring to augment the centrifugal effect for greater torque output at low speed. In an alternative arrangement the annulus 54 may be fixed, the ball ends driving through a sun, e.g. inner race, fast with the output shaft.

Filed: 1972-12-19
Abstract: 1402289 Controlling pumps and motors CATERPILLAR TRACTOR CO 19 Dec 1972 [23 Dec 1971] 58620/72 Heading F1A [Also in Division F2]  A control linkage for a pair of variable displacement pumps or motors 10, 12 of a hydrostatic transmission comprises a pair of levers 42 each of which is, at one end, adjustably connected to a pump or motor displacement actuating element 16 and at the other end is adjustably connected to a link 60 which inter-connects the levers 42. Each lever 42 is pivotally connected to an arm 20 of a bracket 24 carrying two adjusting screws 26, 28 between which is held an arm 22 fast with the pump or motor displacement adjusting mechanism 16. A pin 44 on the other end of the lever 42 engages a slot 46 in a bracket 36 which is pivoted at 38 on a fixed frame. The pin 44 is normally held against the end of the slot 46 by a spring pressed yoke 50. The end position of the slot is adjustable by a screw 48. The brackets 36 are additionally pivoted to the inter-connecting link 60. An hydraulic motor 40 pivots the brackets 36 about their pivot points 38 in unison for equal displacement changes in the pumps or motors. Selective operation of hydraulic motors 34 acts through the yokes 50 to move the pin 44 of the lever 42 along the slot 46 to effect selective displacement changes in the pumps or motors for steering purposes. The pistons 52 of the motors 33 are fast with the yokes 50 and are biased to the position shown by springs 54. The pumps or motors 10, 12 may be in separate hydrostatic transmission or may be motors supplied by a common pump.

Title: Internal combustion engine fuel control system having a full load
IPC: F02D41/34
Filed: 1972-12-20
Abstract: 1364999 Electronic fuel control systems for I C engines BENDIX CORP 20 Dec 1972 [20 Jan 1972] 58694/72 Heading G1N In an I. C. engine, electronic fuel control system, a full-load fuel enrichment circuit is provided to determine when engine operation extends into its full-load range to cause an additional amount of fuel to be supplied, the amount being dependent upon the extent of the operation into the full-load range. As shown in Fig. 3, alternate pulses are applied at 40, 42, in synchronism with engine rotation, to a generating circuit 60, each pulse causing the initiation of a charging voltage across a pair of capacitors, Fig. 5 (not shown) which each produce a waveform 90 as shown in Fig. 6. The portion A-D corresponds to the charging of one capacitor by a first current source during a pulse at 40 and the part above D corresponds to the charging of the same capacitor by a second current source during a pulse at 42. The second capacitor also produces the same waveform but phase displaced by the width of a pulse at 40 or 42 with respect to the waveform shown. The instantaneous output 66 of generator 60 is represented by the highest voltage across the two capacitors. This output is applied to the fuel enrichment circuit and to a circuit 62 which provides pulses for causing energization of injector valve means for their duration. The fuel enrichment circuit is shown in Fig. 4, the voltage on line 66 being compared with a reference voltage R which represent the lower limit of the full-load range. When the voltage on 66 reaches the reference voltage, a transistor 76 is switched which causes a transistor 80 to act as a current sink for one of the capacitors. Thus, the slope of the waveform 90 is reduced above the reference level R as shown in Fig. 6. The circuit 62 initiates a pulse 94 coincident with the generation of a pulse at 42, and compares the voltage on 66, i.e. the waveform 90, with a reference 92 which is determined by at least the intake air-pressure. When the voltage on 66 reaches the reference 92, the pulse 94 is terminated. The duration of pulse 94 determines the duration of injections. Thus, if the reference 92 is above the reference R, the pulse 92 is lengthened due to the change in slope of 90 above R. Other engine parameters, such as temperature, may be used to determine reference 92. Instead of using a current sink, the circuit 64 may add a current to one of the charging current sources, this current being cut-off when the reference R is exceeded.

Title: Record card reading apparatus
IPC: G06K13/08
Filed: 1971-12-21
Abstract: 1367173 Card reader COMPAGNIE HONEYWELL BULL 21 Dec 1971 [21 Dec 1970] 59474/71 Heading G4M A card reader feeds cards from a supply stack 1 via a continuously rotating roller 6 to a roller 7 and a solenoid operated pressure wheel 8. The card travels on an incline and is fed continuously through a reader 12 to a roller 14 and solenoid operated pressure wheel 15. A stop 13 is situated so that the card is halted with its final column of punched holes in a reading position. The card is sensed by a detector B to release pressure on pressure wheel 15 so that the card is not damaged on reaching the stop. The card is then stepped in the opposite direction by stepping motor and roller 16 and solenoid operated pressure wheel and is fed via roller 7 and pressure wheel 9 to an output stack 2 situated beneath the supply stack. The cards are fed with a face carrying printed matter face down and the cards have cut corners on one edge. The reader may be controlled by one of the cards or by a punched tape (Fig. 1, not shown). The reader may contain a keyboard and a printer and may feed a computer. The control circuit is shown in Fig. 3. A power switch HS operates a rectifier GR and a start signal from switch T1 or from a computer S1 sets flip-flop FF2 to start motor 18 driving the rollers via belts and feeds distributer RV. When no card is present in the reader all the photo-cells operate to produce signal GR enabling AND gate E2 to set flip-flop FF3 and operate solenoids M4, M7 and M1 via one shot TU1. At the end of the one shot pulse TU1 differentiator D1 enables AND gate E1. The card is fed towards stop 13 and detector B resets FF3 and sets FF4 to operate solenoid M3 and enable AND gate E3 receiving a further signal when the distributer leaves stop segment 5A. FF5 is set and closes line TL coupled to the computer so that data from the column of the card in the read head is fed serially under the control of the distributer and relays CR to the computer. When stop segment 5A is reached FF3 is reset and a stepping pulse is fed to motor 21. The procedure is repeated for other columns. The reader is stopped by switch T2 or signal S2 from the computer or if a card is not detected at A, when E1 is enabled. The card may be rapidly ejected by switch T3 or signal UC punched on the read card by setting flip-flop FF6 to operate oscillator G to feed high speed stepping pulses to the motor 21.

Abstract: 1364107 Coating apparatus HITACHI SHIP BUILDING & ENG CO Ltd 21 Dec 1971 [26 Dec 1970 22 Jan 1971 17 Sept 1971 21 Sept 1971] 59478/71 Heading B2L A spray gun 12 for coating the outer surface of a ship's hull mounted on a rod 1 axially slidable in a tube 2 which is rotatable about an axis 19 is maintained at a fixed orientation relative to the surface in the plane of the rotational movement by means of pulleys 55, 56 a chain 57 and a chain 59 attached to the spray gun. The pulley 55 is mounted for rotation on a fixed arm 20 and an arm 50 is pivotally attached to the end of arm 20 and rod 1. Rotation of the rod 1 and tube 2 about axis 19 caused by crank arm 41 causes movement of arm 50 as shown in Fig. 3. During this movement the rod 1 slides in tube 2 to maintain the spray gun at the same distance from the surface and the pulley system maintains the same orientation of the spray gun. An additional movement is provided at the extreme ends of the swinging movement so that during the change of direction of the gun excess paint is not deposited in one position. This is produced by the action arm 50 abutting extensions 66 on arms 62 to cause rotation thereof. The rotation causes a wheel to move a chain 73 inwardly so that pulley 55 is given an additional rotation at the extreme position. The tube 2 is rotated through an angle and by means of a driven crank arm 41. Fig. 9 shows a mechanism whereby an air motor 85 rotates a pulley wheel 76 which causes the gun 12 to move up and down under the action of ropes 78. The spray gun is mounted on vertical guides 10 and a carriage 11 slides up and down the guides, a connecting rod 95 connecting the carriage 11 to a driven chain 92. The guides are mounted on a platform 91 and rollers 98 move along a fixed guide bar 97.
