Abstract: 552,831. Sales recording apparatus. HILL, W., and SIMPSON, A. W. Feb. 9, 1942, No. 1695. (Class 106 (i)] A sales recording apparatus with means for printing the exact time at which a particular transaction is recorded has a rotary strip-feeding means, the operating shaft of which carries a snail cam that is arranged to act upon a spring controlled plunger carrying the impression pad, the connection between the plunger and spring providing for lost motion so as to effect a time record without interruption of the feeding movement. In the form shown in Figs. 1 and 2, a casing a with a three part cover b, c and d has a supply of continuous strips of paper h, i arranged in zig-zag form and adapted to be fed over a surface g beneath a writing aperture e in the cover part b. The cover part d is formed with an apertured plate k that supports hour and minute time indicating wheels and date indicating wheels. The date wheels are set manually while the time wheels are driven by an electric clock through a clutch or spring coupling. The record strips are fed between pressure rollers u and frictional discs t on a shaft r that is operated by a crank handle s. The drive is adapted to be interrupted periodically by providing the paper strips with perforations y which permit the rollers u to turn idly until the drive is reestablished by gripping pieces z situated alongside the discs t. After the autographed record portion has passed the writing aperture e a snail cam 11 on the shaft r operates to effect an impression of the time and date wheels on the record strips. The cam co-operates with a roller 12 on a pivoted frame. 13 formed with an extension 15 in the form of a yoke and controlled by springs 16. The yoke 15 engages beneath trunnions on a plunger 18, Fig. 7, slidable in a cylindrical guide 19. The plunger 18 carries an impression pad 20 which underlies the time and date wheels. In order that the action may not interfere with the feeding operation the springs 16, at their lower ends, are formed with elongated loops to provide lost motion between the springs 16 and yoke 15. The impression is made through a pair of ink-ribbons one of which is arranged above the strip h and the other is arranged between the strips. A step by step movement is imparted to the ink ribbons by a pin 23 on the shaft r and a toothed wheel 24. To limit the rotation of the shaft r to one revolution a trin device as shown in Fig. 4 is provided comprising a radial arm 26 on the shaft and a pair of pins 27, 28 interconnected by a spring controlled lever 30 mounted on a guide block 29. In the event of failure in the electric supply to the clock the apparatus is locked against use.

Abstract: 1,160,710. Gas turbine engines. FORD MOTOR CO. Ltd. Dec. 13, 1966 [Dec. 21, 1965], No. 55760/66. Headings F1G and F1T. [Also in Division G3] A gas turbine engine is connected to the wheels of a vehicle through a variable ratio transmission and is controlled by varying the supply of fuel to a combustion chamber by a driver operated element 94 which also controls the position of the turbine nozzles through a servomotor system having a control valve 62 movable to either side of a central position to connect a fluid-pressure source 72 to one side of a movable member 34 for operating the nozzles and a follow up mechanism 100,102, 104 and 106 responsive to the position of the nozzles to recentre the control valve. Depression of the accelerator pedal rotates the element 94 and a cam 92 to relieve the pressure on a cam follower 78 and a spring 74 to permit the valve 62 to be moved to the left by a spring 76. Passages 48 and 46 are thus connected to supply and drain ports 72 and 60, respectively, to cause the member 34 to rotate the nozzles towards their high-power positions until the follow up mechanism has relieved the pressure on the spring 76 for the control valve to be recentred. If, after the vehicle has been accelerated, the accelerator is completely released orifices 120 and 121 in the element 94 register with passages 148 and 154 which have been placed in communication with the pressure source 72 by a valve 126 responsive to vehicle speed so that fluid flows through a passage 119 in the element 94 to raise the pressure in a space 86 having a fixed discharge orifice 88. The follower 78 and valve 62 are thus moved to the right to rotate the nozzles to the maximum braking position. If, at the same time a transmission selector valve 20 is rotated through 90 degrees to the left from the position shown to a neutral position, the passage 154 from the valve 126 is closed and fluid under pressure may be supplied to the space 86 by a valve 158 responsive to engine speed. Pressure in the space 86 is also controlled by a needle-like valve 111 connected to an element 109, 110 responsive to turbine inlet or exit temperature. In a modification, the temperature-responsive pressure acts on the follower 78 through a spring-loaded diaphragm and a yoke extending around the cam 92.
