Title: Improvements in or relating to pig-skin driving belts
IPC: C14B9/00
Filed: 1922-01-04
Abstract: 197,279. Gusdorf, H. M. Jan. 4, 1922. Belts.-A single ply driving-belt is formed of pigskin strips in which the ham end of each strip is joined to the shoulder end of the next strip. The strips are formed from pigskin treated so as to preserve natural cup-like openings in the flesh side, which is employed as the pulley contacting surface, the grain side being substantially inelastic. In joining the strips, the ends to be united are cut obliquely so as to form long bevels a, b, with the thin ends c, d removed to form short bevels, the long bevels being then joined by cementing and pressing. In view of the difference in density between the ham and shoulder ends, the longer bevel at the ham end runs from the flesh side and, at the shoulder-end, from the grain side.

Title: Improvements in or relating to friction clutches
IPC: F16D43/18
Filed: 1920-02-18
Abstract: 153,549. Tuff ery, P., and Demars, G. Oct. 29, 1919, [Convention date]. Clutches, friction.-In friction clutches actuated by centrifugal force as shown in Fig. 1, the driving shaft 1 has a fly-wheel 2 connected to a ring 3, and a cover 5, which acts as a bearing for the driven shaft 6. A plate 7 is connected to the driven shaft. Segments 8 engage radial recesses 10 in the fly-wheel 2, and segments 11 engage radial recesses 13 in the plate 7. On rotation, these segments come into frictional contact by centrifugal force. In a modification this device is employed in combination with an ordinary disk friction clutch, and a free-wheel arrangement is provided to act as a positive brake in reverse. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a method whereby annular disks connected respectively to the driving and driven shafts, are forced into contact by the action of centrifugal force on sliding blocks, which are pivotally connected to a member enclosing the disks. A combination of this method with an ordinary disk friction clutch is described. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to liquid pressure control systems
IPC: F04C14/28
Filed: 1938-02-19
Abstract: 511,298. Rotary pumps; hydraulic machines. AUTOMOTIVE PRODUCTS CO., Ltd., and CHOUINGS, L. C. Feb. 19, 1938, No. 5278. [Class 110 (ii)] [Also in Group XXIX] A reversible pump A is supplied with liquid by a reservoir B, and feeds either side of a slave E to move the piston in one or the other directions. When the pump is stationary, both flow and return passages 20, 21 are connected with the reservoir, and with each other by means of a large clearance between co-operating members in the pumping means. Fig. 1 shows a gear pump with a gear 15 rotated by a shaft 16 and driving a gear 14 mounted on a fixed spindle 17. A pipe 24 leads from the reservoir to a passage 25 which communicates with restricted openings 28, 29, allowing liquid into the casing. A relief opening 30 of V-shape also communicates with the passage 25, the limbs of the V being tangential with regard to the pitch circle of the gear 15. The teeth on the gears have substantial play and the clearance places the passages 20, 21, into communication with the reservoir B by way of the opening 30 while the pump is idle. During operation, the gears are in firm contact, and the opening 30 is isolated from the delivery passage 20 or 21. The gears are coated with rubber 38, or equivalent material, which may be vulcanised to shape. In a modification Fig. 4, a rubber, or the like, bush 44 is mounted within the gear 14, which fits loosely on the spindle 41. Holes 42, 43, allow liquid from the reservoir to pass inside the .bush 44 when the pump is idle, and the liquid to enter the pump through radial passages 45. During operation the bush 44 is pressed against the hole 43 and seals it. The holes 45, 43, lie in different planes. A further modification embodies three gears arranged in a tri-angular casing, the driven gears not being in contact with each other. The driving shaft may have a resilient device adapted to return the shaft through a small angle when the driving force is removed, to ensure clearances being left between each pair of rotors. Fig. 7 shows an eccentric rotor 60 having a pair of sliding vanes 62 spring-pressed apart. The reservoir B, communicates with co-axial openings 67 in the end walls of the casing and rotor. The vanes are a loose fit in the slot 61, but during rotation of the rotor they lag behind pressing against the near walls of the slot. The coating 68 of rubber or the like, is recessed at 69 to produce a lip 70 which is pressed against the wall of the slot 61 when subjected to pressure: A block 71 of rubber, or the like, presses on the rotor 60 having adjusting means 72 to take up wear on the block. Specification 465,410, [Group XXIX], is referred to.

Abstract: 561,012. Cotters. ELECTRIC STEEL FOUNDRY. April 21, 1942, No. 5343. Convention date, April 21, 1941. [Classes 65 (ii) and 89 (ii)] A locking device for a load supporting pin comprises a cotter en - gaging transversely a groove in the pin. A chain repair link comprises sections 1, 2 that may pivot about the pin 3, and each has a load sustaining portion 4 and a slighter end portion 5 seated in a recess in the part 6 of the other section. Transverse holes in the parts 5 register with grooves 14 in the pin 3 and receive cotter pins 16 secured in place by upsetting the ends. The pins may be removed by a hammer and punch. A pin may be similarly secured in a shackle, or one end of the pin may have a head. The pin may be received in holes leading into the grooves in the pin tangentially so that the pin 39, Fig. 9, is bent through a short arc when it passes through the groove, thus giving a greater area of shear and preventing removal of the pin except by a punch.

Title: Improvements relating to electronic circuit arrangements
IPC: H04N9/66
Filed: 1956-02-21
Abstract: 822,554. Colour television. GENERAL ELECTRIC CO. Feb. 21, 1956 [Feb. 21, 1955], No. 5362/56. Class 40 (3). [Also in Group XL (c)] An electronic circuit for mixing two signals is arranged so that amplitude variations in one of the signals has no effect on the output. The invention is described as applied to a synchronous detector for use in colour television, and is concerned more particularly with the elimination from the output of the effects of undesirable low-frequency variations in the amplitude of the sub-carrier reference signal 2, such as noise and field frequency variations imparted by the blanking interruptions in the synchronizing bursts. According to the invention, the cathode circuit 12, 16, 20 of the detector is arranged to present a low impedance at the sub-carrier frequency but a high impedance at low frequencies so that the undesirable amplitude variations at grid 4 produce corresponding variations across resistor 20. These variations are then arranged to act in effect in opposition in the circuit of grid 26 receiving the sub-carrier signal 22 by ensuring that grid 26 is at earth potential for low-frequency variations. By appropriate selection of resistor 20 complete cancellation is effected such that variations in the anode output imparted by grid 2 are offset by those imparted by grid 26. The coupling circuit 8, 10 for the reference signal has a time constant short enough to permit the grid to follow the low-frequency variations, but not so short as to introduce more than a few degrees phase-shift at sub-carrier frequency. The impedance of the coupling circuit 24, 28, 30 to grid 26 is made such that grid 26 is at earth potential for low-frequency variations. Fig. 2 (not shown), illustrates a second embodiment comprising two synchronizing detectors which have a common cathode feed-back resistor 20 for cancelling out the variations.

Abstract: 910,190. Audible signalling - apparatus. KIDDE CO. Ltd., WALTER. Feb. 10, 1960 [Feb. 17, 1959], No. 5456/59. Class 118. A device which gives an audible signal when the pressure of a gas exceeds a predetermined value comprises a whistle 4, or like gas-pressure operated signalling means, to which gas is admitted via a body 1, and a valve 5 spring- loaded towards its seating 6 by a spring 7 and unseated when the gas-pressure exceeds the predetermined value, the gas being admitted to the body 1 through an inlet 2 having an orifice 3 of smaller effective aperture than the whistle 4 or like means, so that when the valve 5 is unseated the pressure in the body 1 cannot be maintained, and the valve 5 closes, this resulting in the emission of an intermittent note. A second valve 8 is provided between the orifice 3 and the first valve 5, the piston of valve 8 being fluted and normally held off its seating 10 by the spring 11 so that gas passes to the valve 5. The supply of gas to the whistle 4 may be cut off by pressing the manual control button 9 to bring the piston of valve 8 into contact with the seating 10, the spring 11 being unable to unseat valve 8 while the gas pressure exceeds the predetermined value.
