Abstract: 1,226,608. 608. Rotary positive-displacement pumps. G.G. HARVEY. May 9, 1968 [May 11, 1967], No.22000/68. Heading F1F. [Also in Division F2] The speed of an output shaft 2A driven through a variable speed planet gear 1.. from an electric motor is maintained constant by speed responsive control of a hydraulic pump 6 which controls the ratio of the planet gear. As shown planets 2 on an output carrier 9 mesh an input sun gear 1 and a reaction ring gear 3 which drives the hydraulic pump 6. The flow of liquid through the pump 6 is controlled by a valve 12 which is operated by a governor 7 responsive to the speed of the output shaft 2A. A decrease in output shaft speed causes the valve 12 to close and increase the braking on the ring gear 3 and thus increase the output shaft speed. If an overload on the output shaft causes a decrease of the input shaft speed, a governor 10 on the input shaft opens the valve 12 to prevent damage to the driving electric motor. Excessive pressure in the pump 6 opens the valve 12 to relieve the excess pressure and prevent damage to the pump. The liquid from the pump 6 is returned to a reservoir 5 through a cooler 11. Hydraulic braking. The pump 6 comprises an eccentric rotor 15 carrying vanes 16 which are held against a freely rotatable ring 18 by centrifugal force. The liquid discharged from compression chambers 25, 24 flows through ducts 19A, 19, past the valve 12 to an outlet A. As the valve 12 closes the discharge from chambers 24, 25 is throttled to brake the rotor 15 and ring gear 3. The vanes 16 are additionally urged into engagement with the ring 18 by the pressure in chambers 24, 25 which acts beneath the vanes. During reverse rotation of the rotor 15 (i.e. during overrun) the fluid wedge between the vanes 16 and ring 18 overcomes the centrifugal force on the vanes and moves the latter radially inward to permit the rotor to free-wheel. The vanes 16 may, as shown, have a circular section and carry weights 17 or they may have a rectangular section. In Fig. 3 (not shown) the pump rotor (15) surrounds and is fast with the ring gear (3). The rotor cavities carrying the vanes are wider than the vanes and the discharge from the chambers passes between the vanes and the cavity sidewall. Braking is provided for both directions of rotation.

Abstract: 1,231,894. Cine cameras. EASTMAN KODAK CO. June 26, 1968, [June 28, 1967], No.30449/68 Heading G2E. In a cine camera having an electric motor for driving the shutter, rotation of the motor automatically releases a brake on the shutter. To start the camera, a slide-member is depressed causing manual rotation of the motor shaft until a switch is engaged by the slide-member to switch on the motor. As shown, a rotatable shutter 17 is mounted on a shaft 11 connected through gears 14, 15, 16 to a shaft 12 of an electric motor 13 having a battery 52. Depression of a button 25 moves a slide 22, allowing a latch 26 to drop and lower a rack plate 33 through engagement of an ear 41 and an upwardly extending tooth 39. This horizontally aligns a rack 54 with a pinion 53 on the motor shaft 12. Further movement of the slide 22 moves the plate 33 through engagement of surfaces 57, 58. Members 53, 54 then engage so manually rotating the shaft 12. A lug 45 on the rack 33 abuts a strap 46 and closes motor switch contacts 49, 50. With the motor 13 switched on the shaft 12 rotates and moves the rack 33 further to the right through members 53, 54.

Abstract: 1,233,365. Arrangements for identifying articles. MOLINS MACHINE CO. Ltd. 12 Sept., 1968 [13 Sept., 1967], No. 41870/67. Heading G4H. Apparatus for sensing identifying marks on articles constituted by combinations of magnetic and non-magnetic material carried by articles at predetermined positions to represent a binary number, comprises at least one electromagnetic sensing device having a magnetic circuit in which the markers produce an electric output. The magnetic marks representing " 1's " are constituted by plugs 17 of magnetic material in holes in the article 16. Binary " 0's " are represented by plugs 18 of non- magnetic material or by empty holes. If the article is magnetic " 1 " positions may be represented by blank areas, and if non-magnetic, " 0 " may be represented by a blank area. A sensing device includes a coil 13 which is supplied with A.C. through a series resistor. The voltage across the coil, which varies when the core is adjacent a magnetic plug, is rectified, smoothed and amplified in a transistor. A similar sensing coil senses a blank or non- magnetic position and the rectified output is subtracted from all the other sensing coil outputs. The subtracted voltage is arranged to be about 20% more than the output of a coil sensing a " 0 position and about 20% less than the output of a coil sensing a " 1 " position. An output transistor gives a signal only when a " 1 " position is being sensed. If there are 15 binary positions, twelve may represent a binary number and three a modulus-seven check. There may be only a single sensing coil reading the binary positions in succession as the article moves past. The serial signals are entered into a fifteen-stage shift register. Readout may be in serial or in parallel mode.
