Filed: 1939-07-21
Abstract: 531,921. Variable speed gearing. PITTER, W. C. July 21, 1939, No. 21234. [Class 80 (ii)] Relates to speed changing gear of the kind described in Specification 242,378, [Class 80 (ii)], in which planetary pinions 15 gear with a fixed sun wheel 22, and are driven through a one-way clutch from an oscillatory crank 38 the throw of which can be varied and in which the planet carrier 17 forms the driven member. According to the invention the gear is provided with variable throw mechanism including a plurality of discs 18 ... 21 on the driving shaft which passes straight through the discs, one, 18, of which forms a variable throw eccentric. As shown, the discs 18, 19 are eccentrically mounted 180 degrees out of phase and are pivoted on pins 26, 27, fixed at diametrically opposed positions on disc 20 fixed to shaft 13. Diametrically opposite pins 28, 29 on the disc 21 engage slots 28d, 29b in the discs 18, 19 respectively so that relative angular movement between the disc 21 and the shaft 13 will vary the eccentricity of the discs 18, 19 in opposite directions. The discs 19, 20 are slotted to allow a clearance passage for the pin 28. Mounted on the disc 18 on rollers 35 is a ring 34 having an annular groove 36 in which work slippers 37 mounted on the crank pins 38a of the cranks 38. A disc 40 to balance the ring 34 is mounted on the disc 19. The disc 21 is fixed to a sleeve 25 pinned at 62 to a drive shaft 13a. The shaft 13 is driven from the sleeve 25 by pins 66. The latter are carried on a sleeve 67 slidable on the sleeve 25 and pass through helical slots 65 in the sleeve 25 and are fixed to a nut 59. This is helically splined to the shaft 13. A handwheel 74 has screwed engagement with a non-rotatable thrust ring 68. Upon rotation of the handwheel 74 the sleeve 67 is slid along the shaft and relative angular displacement of the sleeve 25 and shaft 13 occurs producing change in the throw of the eccentric discs 18, 19. In a modification, axial movement of the thrust ring 68 is produced by a pair of screwed rods which are geared together and one of which is manually rotated by helical gearing.

Title: Method of removing synchronising pulses from a television signal
IPC: H04N5/08
Filed: 1958-07-03
Abstract: 893,877. Television. STANDARD TELEPHONES & CABLES Ltd. July 3, 1958 [July 13, 1957], No. 21294/58. Class 40(3). In an arrangement for separating synchronizing pulses from a composite television signal the latter is supplied with opposite polarity to two grids of the hexode section of a triode-hexode valve and the separated synchronizing pulses derived from the anode (terminal 19) of this section the control grid of which is so biased that this section is cut-off by negatively going noise pulses extending beyond the peaks of the synchronizing pulses. To prevent the cut-off level from occurring at the wrong point if the amplitude of the input signal changes the separated pulses are supplied to the grid of the triode section and the resulting pulses in the anode circuit of this section, which are integrated by resistor 2 and capacitor 5, vary the bias on the control grid of the hexode section to maintain the cut-off point at the optimum level for separation of the synchronizing pulses.

Title: Improvements in and relating to the raising of natural oil and other liquids by gaseous pressure
IPC: F04B47/00
Filed: 1946-07-22
Abstract: 616,887. Raising liquids. BROWN, N. F. July 22, 1946, No. 21800. [Class 102 (ii)] An apparatus for raising liquid in wells by gas pressure consists of an eduction pipe 11 supported by a collar 10 on the upper end of a hollow rod 9 secured to a piston 7 within a cylinder 6. The apparatus is controlled by an electromagnetic valve unit A comprising an armature 17 serving as a valve and actuated by coils 15, whereby gas under high pressure can flow from pipes 14 and 21 through a valve seat 18 and a pipe 22 to a cylinder 23 to depress a piston 25 which in turn forces liquid through a pipe 26 and a valve 28 to the cylinder 6, to raise the piston 7, after which the valve 28 closes under the action of a spring 27. The high pressure gas in the pipe 22 also actuates a piston 30 which forces a roller 33, on a pivoted trip lever 31, beneath an abutment 34. The closing of the armature 17 on the valve seat 18, and the simultaneous opening of valve seat 20, by switching-off the current to the coils 15 allow the gas in the cylinder 23 and pipe 22 to infiltrate through slots in the armature 17 to a pipe 35 leading to a low-pressure pipe 4. The oil slug which flows through a pipe 36 to a chamber 37, having a restriction 38, actuates a diaphragm 40 and a rod 42 to release the roller 33 and the trip lever 31 which is forced upwards by a spring 32 to open the valve 28, thereby allowing the piston 7 to fall ready for the next lifting operation. Specifications 584,410 and 616,885 are referred to.
