Abstract: 1,051,067. Control of motors. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept. 3, 1963 [Sept. 5, 1962], No. 33983/62. Heading H2J. [Also in Division H3] A control circuit for a windscreen wiper motor 8, 9 includes a thyristor 15 in parallel with a switch 11 and the arrangement is such that, for light rain conditions, the wiper remains in a parked position for a time after each single operating cycle. A manual switch 12 has a continuous running position 13 and a position 14 in which the motor circuit is completed through the thyristor 15. Movement of the motor closes switch 11 to keep the motor running until the parked position is regained, the thyristor meanwhile having been switched off by the opening of relay contact 16 in its triggering circuit. The relay is held open after switch 11 has opened by the discharge of a capacitor 21 through its winding 22; at the end of this delay the contact 16 closes to trigger the rectifier and thus cause the wiper to operate for another single cycle. A diode 18 prevents the thyristor being switched on by the back E.M.F. of the motor when switch 11 opens. Various modifications in detail of this circuit are described, and in an alternative embodiment (Fig. 2, not shown), the relay is replaced by a transistor and two capacitors are used across a potential divider, the arrangement being such that any supply transients appear equally at the base and the emitter of the transistor. In this circuit the delay is adjustable.

Abstract: 1,230,961. Mechanical calculating apparatus. NATIONAL CASH REGISTER CO. 7 Jan., 1970 [15 Jan., 1969], No. 789/70. Headings G4B and G4T. A notched aligner member 45 prevents the movement of the unselected totalizers in a group of four interspersed totalizers mounted on shaft 20. For each of the seven decades is provided a subtract pinion 23 and an add pinion 24, which constitute an add-subtract totalizer; a selective itemizer pinion 25; and a group totalizer pinion 26. In their inoperative position the pinions are locked by member 42, Fig. 1. Rotation of actuating arm 40 on shaft 38 lifts the pinions away from member 42 into contact with actuators 54, Fig. 4. Shaft 20 is laterally shiftable under control of transaction keys to align the pinions of the chosen totalizer with the actuators 54. Accidental rotation of the remaining totalizer pinions is prevented by notched aligner 45. For operation of the subtract pinion 23, aligner 45 is shifted to the right with relation to the totalizers by action of spring 52 until a lower stop portion 55 of the aligner engages the frame 22. In this position the wide stop portion 47 of the aligner engages both the selective itemizer pinion 25 and the group totalizer pinion 26, while the narrow stop portion 48 is positioned between the linked add pinion 24 and the subtract pinion 23, thus allowing both pinions to be rotated by the amount actuator 54. When the add pinion 24 is selected to be operated by actuator 54 (Fig. 5), shaft 20, frames 21, 22, aligner 45, shaft 27 and plate 53 are shifted in step to the right so that the aligner 45 maintains its position with relation to the totalizer pinions. When the totalizer assembly is shifted further to the right to align the selective itemizer pinion 25 (Fig. 6) with actuator 54, movement of aligner 45 is prevented, despite the tension in spring 52, by engagement of plate 30 with the lower shoulder portion 50 of the aligner. In this position the stop portion 47 engages the group totalizer pinions 26 and the subtract pinions 23 of the next amount bank. The stop portion 48 of the aligner engages the add pinions 24, thus leaving the selective itemizer pinion 25 free for rotation by actuator 54. When the group totalizer pinion 26 is to be aligned with actuator 54, the totalizer assembly is shifted farther to the right (Fig. 7), whilst aligner 45 is held in place by plate 30. Stop portion 47 engages subtract pinion 23, thereby also preventing rotation of linked add pinion 24, and stop portion 48 engages the selective itemizer pinion 25, leaving the group totalizer pinion 26 free to be rotated by actuator 54.

Abstract: 1,231,266. Fluid-pressure servomotor systems. CKD PRAHA, OBOROVY PODNIK. June 27, 1968 [July 1, 1967, Oct.31 1967, June 5,1968], No.30701/68. Heading G3P. A governor for compression ignition engines, comprises centrifugal weights 1 loaded by a spring 2, actuating a slide valve 3 distributing oil to a piston and cylinder 6, 5 which by rectilinear motion controls a lever 33 on a shaft 34 of a fuel metering device in a injection pump, the piston 6 having at least one oblique control surface 7 co-operating with an overflow bore 11 in the wall of the cylinder 5, and being rotatively mounted within the cylinder, and connected to a speed control lever 28 through a linkage 22, 27, and with the shaft 34. The valve 3 is connected with the cylinder 5 via an overpressure duct 8 and a pressure duct 9 connecting, respectively, with the upper and lower parts of the cylinder to actuate the differential piston 6 which has a larger upper face. The piston 6 has a plunger 14 in a cylinder which connects with a cylinder of a compensating piston 16 communicating with the valve 3, and a bleed outlet controlled by a needle valve 18. The piston 6 is rotatable by a fuel lever 20. In operation, to start the engine, the speed lever 28 is set to increase the loading of the spring 2, and the fuel lever 20 is rotated to a starting fuel charge defined by the height of the surface 7 above the bore 11, and an oil pump connected with inlet 12 is put into action. Oil is passed to both sides of the piston 6 via passages 8 and 9, and the movement of piston 6 is controlled by the weights 1 and valve 3 until the pressure above the piston escapes through the bore 11 and the engine output is controlled at the setting of the fuel lever 20. When the engine has started, the speed lever 28 is set to the required engine speed, and when the forces acting on the weights 1 are balanced by the spring 2, the valve 3 closes duct 8. If the fuel charge is insufficient for the load the engine speed drops, and valve 3 uncovers duct 8 to cause piston 6 to move down and increase the fuel charge until the engine speed is restored. In Figs. 2, 3 and 4 (not shown), a piston (6) has four oblique surfaces (7) forming two opposite charging chambers (35) connected through ports (37), and two opposite outlet chambers (36) connected with the outlet (11) via ports (38). In Figs. 5 to 8 (not shown), the fuel lever (20) rotates the cylinder (5) with respect to the piston(6), and the speed lever (28) rotates the piston (6) via rods (52), (53) and bevel gears (48), (49) as well as adjusting the governor spring (2) via gears (57), (57<SP>1</SP> ) and levers (58), (59). Ports (39) from the charging chambers 35, and ports (11) from the outlet chambers (36) connect with opposite sides of a rotary piston motor (43) to actuate a rheostat (47) in the field windings of a diesel-electric generator. In Fig. 10 (not shown), a cam (68) is interposed in the linkage between the speed lever (28) and the rotatable piston(6).

A casing hanger 10 is lowered into, and seated in, a casing head D on a running tool C, the hanger and a packing and locking assembly 46 being releasably secured to the tool by dogs 11, 71 respectively. A dart (111, Fig. 2a not shown) is seated in the bore 101 of the tool, and fluid is directed to a chamber 36 to raise a sleeve 21 and release the hanger. The tool is lowered, to shift packing 55, 54, 56 of the assembly into annulus 105 between the head and hanger, and to cause the hanger extension 83 to retract dogs 71 from the assembly. Further downward movement of the tool brings hanger locking dogs 57 on the assembly opposite a groove 62 in the head and forces a lock sleeve 47 to urge dogs 57 into the groove and compress the packing against a seat 118 on the hanger to seal the annulus 105. Blow out preventers (not shown) are closed and fluid is supplied to the annulus 110 to move the tool downwardly to force dogs 57 further into the groove and further compress the packing. As the hanger it fixedly set the tool is removed. If the setting of the hanger is not successful the assembly 46 is removed by a tool which engages grooves 48 on the sleeve 47. After the hanger has been lowered into the well and prior to setting, the casing E supported by the hanger is cemented, cement passing upwardly through ducts 102 in the hanger, annulus 103, slots 104 in the hanger, annulus 105, holes 108 in the hanger and passages 69 in the tool. The arrangement is suitable for sub-aqueous wells.

A transistor oscillator suitable for a telephone key sender, includes an RC frequency determining feedback network TTF (e.g. a Twin Tee filter) and a limiting circuit QA, QB, QC, and all the transistors share the same environmental temperature, as by incorporating them into a silicon chip, to stabilize the limiting circuit against temperature variations. In operation, one of an array of push buttons PB is pressed, inserting corresponding components into Twin Tee filters to produce a burst of oscillations from a high frequency oscillator and from a low frequency oscillator, each oscillation having one of four values. In each oscillator, during the positive peaks of cycles at point B, transistor QC conducts to provide negative feedback to the base of transistor Q2, thus limiting the negative peaks. To stabilize the action of the limiting circuit against variations in supply voltage, points A and B are biased to the same potential by making R1 and R2 equal to the average resistance of the filter and by making R3 and R5 equal.
