Abstract: 1,256,244. Fuel (fluid) dispensing apparatus. VEEDER-ROOT Ltd. Oct. 2, 1969 [Oct. 2, 1968], No. 46717/68. Heading A4T. A fuel dispenser has pump 10, Fig. 1, driven by motor 12 controlled by switch 111, a meter 14 driving cost 22 and volume 24 registers via variator 27, the meter leading through a shut-off valve 16 to a hose nozzle 18, and a manual control lever 32 rotated to "off" position to permit the nozzle to be placed in boot 30, and from which the nozzle is removed to permit lever 32 to rotate to "on" position. When lever 32 is pivoted "on", a constant speed motor 56 is switched on at 52 via over-center loaded cam 54 on shaft 42 carrying lever 40, Fig. 2. The motor continually drives gears 60, 62 and ratchet wheels 66, 68 which when pawls 72, 76 selectively engage them, drive gear 70 and register reset shaft 28 or gears 74, 75 and shaft 104 of cost/volume printer 92. With clockwise "on" rotation of shaft 42 and lever 40, Fig. 2, trip lever 80 withdraws spring-loaded lever latch 82 permitting pawl 72 to engage ratchet wheel 66, then engages stop 84 to release latch 82 to engage edge 86 of pawl 72 ready to hold the pawl when automatically released after one revolution of reset shaft 28. Slightly before the one revolution, stud 90 on gear 70 pivots lever 91 counterclockwise to latch in spring lever 93 and via link 110, open valve 16 and switch on pump motor 12 at 111. A timer 120 automatically terminates dispensing after a predetermined time adjustable by stop 140. Upward movment of link 110 to open valve 16 after resetting engages gear sector 130 with the last of gear train 62, 122-128 which is a time measure of operation of motor 56. After the predetermined time, pin 136 shifts lever 138 to disengage latch 93 from lever 91 so that spring- loaded link 110 closes valve 16 and stops pump motor and lifts sector 130 away from gear 126 so that it swings to abut stop 139. Fuel dispensing is manually stopped by turning control lever 32 to "off" whereby lever 40 engages and releases catch 93 from delivery valve and pump control rod 110, but motor 56 remains energized. Lever 40, Fig. 3, via link 144, lever 146 and spring trip pawl 149 is also turned and disengages latch 140 from a sprung pawl 76 so that it engages ratchet wheel 68. The motor 56 gives printer shaft 104 one complete revolution after which latch 140, released by trip pawl 149 to engage pawl surface 152, holds the automatically released pawl 76 disengaged. The cost and volume counters of the printer 92 are operated from the register via shafts 94, 95 and after one revolution of shaft 104, cam 160 on gear 74 engages follower 162 and via lever linkage 164. 46, pivots shaft 42 anti-clockwise to de-energize motor 56.

Abstract: 1485788 Automatic phase control RCA CORPORATION 11 Feb 1975 46962/74 Heading H3A In a generator for supplying constant width drive pulses to a television deflection circuit 50, a phase comparator 24 provides a correction signal D in response to the phase relationship between a ramp signal C and a pulse F from the deflection circuit 50. A constant current source 60 and impedance 58 derives a lower voltage correction signal from the signal at D, the two correction signals being fed to respective signal level comparators 66, 68; 76, 78 which are coupled to a drive source 88 for controlling the deflection circuit 50 in such a way that comparison of the ramp C with the first correction signal D initiates a pulse at E to trigger the deflection circuit 50 whilst the comparison between the ramp C and the second correction signal terminates the pulse at E. As described, the ramp C is part of a triangular wave, Fig. 2C, which is synchronized with sync. pulses, Fig. 2A, by means of a further loop including comparator 16. A control signal generator 34 also provides a square wave, Fig. 2B, which is fed to transistors 70, 74 in the first and second signal level comparators so that comparison only takes place during the negative-going ramp. The phase comparator 24 utilizes a voltage comparator, comparing the instantaneous value of the ramp C with a D.C. reference 18, but, since the comparator 24 is only enabled during the flyback pulse F from the deflection circuit 50, the correction signal output D is a function of the phase relationship between the ramp and pulse F. It is stated that due to loading on the deflection circuit 50, the phase delay between E and F may be variable, this variation being corrected by the action of the main loop including the phase comparator 24.

An antiskid braking system in which the brakes are controlled via a modulating valve 24 actuable to relieve fluid pressure or apply fluid pressure comprises a control circuit having means responsive to a signal indicative, in operation of the system, of variations in the coefficient of friction between the wheel and the road surface for varying the time interval of pressure reapplication, the interval being shorter when the signal is indicative of higher values of coefficient of friction than when the signal is indicative of lower values of the coefficient of friction. The control circuit includes a first rate detector section 52 having a threshold selector 60 connected thereto and a fourth rate detector section 58 senses spin up and operates on the section 60 to vary the  threshold at which section 52 operates, this resulting in delaying the time in a skid cycle at which an output section 76 operates. A memory circuit provides that the signal from section 58 varies the threshold of section 52 for the next skid control cycle.
