Title: Register resetting mechanism
IPC: G06M1/28
Filed: 1970-08-10
Abstract: 1325355 Zeroizing mechanisms SUN OIL CO 10 Aug 1970 [18 Aug 1969] 38427/70 Heading G4D Zeroizing mechanism, especially for a selfservice petrol pump, comprises a shaft which is rotated in one direction to couple the register to a gear for zeroizing, and then in the opposite direction to uncouple this drive and connect the register to another gear for counting. When a dispensing operation is completed a reset motor 22 drives a crank 160 and cam 134 through a quarter-turn to shift slide 138 longitudinally and drive the register shafts axially so that gears 42 are disengaged from the usual quantity and cost drives 38, while gears 106 individual to each numeral wheel are connected to reset gears 124. At the same time plate 180, Fig. 5, is turned counter-clockwise through 90 degrees without effect on drive plate 184. When the next dispensing operation is to begin the reset motor again drives the crank 160 but in the opposite sense. Pawl 200 on plate 180 turns drive-plate 184 through a quarter turn so that gear 130 drives gears 128, shafts 126 and reset gears 124 to restore the numeral wheels via gears 106. A detent pawl 204 is rendered inactive during this operation. The cam 134 is ineffective until the last 30 degrees of the rotation when it shifts slide 138 to disengage the zeroizing drive and restore the counting drive.

[Class 102 (i).] In a fuel pump of the kind comprising a piston a having axial and radial passages b, c and working in a cylinder e provided with radial inlet ports g controlled by the piston, the end of the injection period being regulated by a sleeve which controls the opening of the passage b, the sleeve is arranged to be moved by the piston during its strokes until it is arrested by a fixed stop n and an adjustable stop l<1> carried by a sleeve l. By this arrangement, fuel enters the barrel d during the whole suction stroke, first through the passages b, c, and then through the ports g. The sleeve l may be adjusted axially for the purpose of varying the end of injection by means of a rack m engaging teeth l<2> on the sleeve, which has a screw-threaded engagement l<3> with the pump casing. In the form shown in Fig. 7, the piston is fixed and the cylinder e reciprocates, the sleeve being moved in one direction by an axially-adjustable sleeve l on the cylinder engaging pins j<1>, and in the other direction by heads r<1> on rods r carried by the cylinder.

Abstract: 901,608. Polishing. AEROSTYLE Ltd. Dec. 2, 1958 [Dec. 12, 1957], No. 38672/57. Class 60.  A device for applying an abrasive or polishing preparation to a rotary mop 4 comprises a spreader 1 and means 14, such as a gun or nozzle, for applying it to the mop periphery on the side of the spreader opposing the direction of rotation. The spreader has a contact face of hard material, e.g. glass, and is operated by a ram 3, the cylinder 5 being carried on a pivoted arm 6 on which the gun 14 is mounted, the ram extending radially of the mop when the spreader is in contact therewith so that the preparation is sprayed tangentially towards the contact zone. The spray-gun is preferably of the automatic type which operates directly air is supplied. A branch air-line 18 to the cylinder 5 from the gun moves the spreader towards the mop in opposition to a spring 9 which retracts it when the air supply to the gun ceases. An adjustable tensioning-screw 17 and spring 15 enable variation of the contact pressure to be made and maintains the gun in its tangentially spraying position as the mop wears, until a stop 20 contacts the frame 21. When spraying pressure is applied, the spreader is thrust into contact with the mop, lifting the spray-gun to its correct position against the action of the spring 15. The polishing preparation may be in liquid or paste form and be squirted through a nozzle from a pressure-feed container.

Title: Motor control system with compensation for low-frequency varia tions in motor energizing voltage

Abstract: 1362868 Automatic voltage control BORGWARNER CORP 23 Aug 1971 [25 Sept 1970] 39413/71 Heading G3R [Also in Divisions H2 and H3] A control system for a synchronous or induction motor 10 supplied from an A.C. supply through a rectifier 13 and inverter 12, comprises a voltage controlled oscillator 15 supplying a signal at 17 consisting of timing pulses whose frequency can be adjusted to regulate the switching instants of the silicon controlled rectifiers of the inverter 12, and a phase shift stabilizer 20 which selectively shifts the phase of the timing pulses whilst maintaining constant their average frequency, the phase shift being produced by a control signal derived from a rectifier 22 representative of low frequency variations of the output voltage of the inverter 12 and being effective to compensate for these variations. As shown in Fig. 3, the signal from the oscillator 15 is applied to a sawtooth generator 30 having a feedback control loop 31 to maintain constant the amplitude of the sawtooth waveform with variations of the frequency of the oscillator signal. The signal from the rectifier 22 is applied to an active filter 35 which removes the high frequency component in the signal, Fig.7B (not shown) to produce a low frequency signal, Fig.7C (not shown) which, after processing by a clipper circuit 37, is combined with the sawtooth signal to produce a resultant signal applied to one input of a comparator 44, whose other input receives a reference signal 46. Variations of the low  frequency signal vary the position of the sawtooth waveform relative to the reference signal, Fig. 7E (not shown) and hence the position of the leading edge of pulses produced by the comparator, Fig. 7F (not shown), which pulses are applied to the driver stage 18 of the inverter after transformation to firing signal form, Fig. 7G (not shown). Instead of obtaining the control signal from a rectifier connected to the output of the inverter, Fig. 8 (not shown), the signal may be obtained from the current in the D.C. bus between members 12, 13, Fig. 9 (not shown) or from the D.C. bus power, the inverter power factor or the turn-off time of the inverter SCR's. Single phase operation is envisaged. Members 30, 35, 37 and 44 are described, Figs. 4, 5 and 6 (not shown).
