Patent GB-328632-A (GB)
Title: Improvements in and relating to jacquard mechanism for looms
IPC: D03C3/24
Filed: 1929-02-01
Abstract: 328,632. Morton, J., and Morton Sundour Fabrics, Ltd. Feb. 1, 1929. Jacquards.-In a twilling jacquard, the pattern cylinder 14, Figs. 1 and 3, and the twilling cylinder 18 are arranged at opposite ends of the jacquard and are operated so as to act on their respective needles simultaneously. The cylinders are carried by rods 16, 20 slidably mounted on the frame 13, and reciprocated by lever movements from an oscillating shaft 26. The cylinder 18 operates two supplementary sets of needles 64 and 72, the former moving pivoted rods 60 to turn the griffe blades 50 so that they cannot engage the pattern hooks, whilst the latter control hooks 70, which, when engaged by the griffe blades, raise bars 55 and cause a complete row of pattern hooks to be lifted. The selvedge hooks 80 are controlled by the supplementary cards. A lag chain 45, with removable pegs 46 acting on a lever 42, renders inoperative at certain intervals the hook 36 which gives the rotatory movement to the pattern cylinder; a similar appliance may be fitted to the supplementary cylinder. Specification 19409/08 is referred to.
Patent GB-639922-A (GB)
Title: Electrical control systems, particularly systems applicable to the synchronization of oscillators, and to detectors of frequency or phase modulation
IPC: H03L7/06
Filed: 1946-02-04
Abstract: 639,922. Automatic frequency control systems. PHILCO RADIO & TELEVISION CORPORATION. Feb. 4, 1946, No: 3494. Convention date, Feb. 3, 1945. [Class 38 (iv)] [Also in Group XL (c)] A frequency discriminator for use in automatic frequency control comprises a variable source and a reference source feeding the respective grids of a phase detector, the output of which is coupled back to the reference source with the interposition of a quadrature network. As shown in Fig. 3, the variable wave is applied to a control electrode 10 of a heptode mixer valve 9, and a wave from a local back-coupled oscillator valve 19 is fed to the other control grid 11 of the heptode. The anode circuit of the latter includes a damped oscillatory circuit 13 tuned to the centre frequency of the variable wave and inductively coupled to the tank circuit 20 of the valve 19. The frequency of the local oscillations depends partly on the tuning of the tank circuit'20 and partly on the strength of the quadrature feedback provided by the coupling 15, 20. When the grid 10 is energized at the centre frequency, the oscillations in the circuit 13 are at a normal amplitude, and the local oscillation is also at the centre frequency, the grids 10, 11 being energized in phase quadrature. As the variable wave deviates, the phase relation of the grids is disturbed, the excitation of the circuit 13 increases or decreases, bringing the local oscillation into frequency agreement with the variable wave, but with such a phase relation between the voltages on grids 10, 11 as will maintain a suitable degree of quadrature feedback at the coupling 15, 20. The changes in the oscillatory anode current of the valve 9 are accompanied by changes in. the D.C. component which follows the fluctuations in frequency of the input wave and produces a control voltage across the resistance R, which may be used to correct the frequency of the variable wave. The separate local oscillator 19 may be omitted, and the cathode, control grid 11, and screen 28 of the heptode valve 9 may be arranged to produce the local oscillation, Figs. 7 and 8 (not shown). The valve 9 is preferably operated under Class C conditions, so that its anode current is in the form of a series of short pulses, which vary in amplitude according to the phase relation between the grid voltages. The circuit does not respond to amplitude changes in the input wave. The local oscillator may operate at a sub-harmonic of the input frequency, as in Specification 566,255, [Group XL (c)]. In a modification, Fig. 9, the local oscillator valve 53 has a grid tank circuit 55 back-coupled to a cathode coil 56. A phasing-circuit 61, 62 is connected across the tank circuit and the junction 60 feeds a quadrature voltage to the heptode grid 11, causing a quadrature feed into the tank circuit 55 which lies in the heptode anode circuit. Specifications 555,618, [Group XL (c)], 562,993, [Group XL], and 639,980 are referred to.

Abstract: 486,905. Injector apparatus for compressing air. DELL, N. E. Feb. 8, 1937, No. 3753. [Class 71] In air entraining and compressing apparatus of the type set forth in Specification 445,337, the water falls through a vertical pipe and the air enters an inverted pipe of conical form therein. Feeding-pipes extend from the conical pipe into the water flow and increase in length in proportion to the decrease in diameter in the conical pipe. An inverted, elongated conical pipe 1 is positioned in the upper end of the falling-water pipe leg 2 of the water - circulating U-pipe 3. The upper diameter of pipe 1 is greater than half the diameter of pipe 2 ; the lower portion is of a diameter less than a quarter of the diameter of pipe 2. Downwardly - projecting, open tubes 4 radiate from the cone. The pipe 1 has an upper end 7 by which it is adjustably supported, housed in a vertical pipe 6 projecting from a chamber 5 on the pipe 3. The pipes 7, 1 are connected by a part of frustoconical form over which the water flows. The pipe 1 ends in a pipe 12 stationed from the walls of the pipe 2 by radial arms 14. The ends of the tubes 4 project to points substantially centrally of the distance between the cone and the inner wall of the pipe 2.

Apparatus for the fluid pressure testing of tubes has means for carrying tubes to and from a testing position and means for testing a number of tubes for leakage at that position by applying thereto internal fluid pressure, and there is adjacent each tube under test an ejector 3 having means responsive to the fluid pressure in the tube which actuates the ejector only after the tube has been released from the means for applying the fluid pressure to the tube so as to displace the tube, if faulty, from the path followed by satisfactory tubes, the pressure responsive means being set in operation only when the pressure in a tube under test fails to be maintained at a prescribed value for a prescribed time. As shown, the testing mechanism 1 and an associated rinsing mechanism 2 are mounted in an inclined position and the ejectors comprise pneumatically or hydraulically operated pistons which act directly on the tubes. On completion of the testing operation a time relay is actuated which operates by electric switch elements those ejectors located beneath tubes in which the prescribed pressure has not been maintained for a certain period of time and these faulty tubes are thrown on to a conveyer 4. Tubes which pass the test are delivered by the conveyer chains 5 to a ramp 6.
