Abstract: 570,538. Electroplating. CRUICKSHANK, Ltd., R., OLLARD, E. A., and POTTS, S. Oct. 8, 1943, No. 16521. [Class 41] [Also in Groups II and XXXVII] Apparatus adapted automatically to convey articles through a succession of baths in, for example, an electroplating process, comprises a carriage movable along a horizontal track and carrying a vertically-movable work-support, the carriage and support being driven by electromagnetic means adapted to be started by automatic switch-gear, which is responsive to electric impulses and is opened by trip pieces for stopping the driving means at appropriate positions along the track. The latter comprises a pair of rails a supporting one or more carriages c by means of wheels d and a roller e. Bus-bars s between the rails a supply, at low voltage and through collectors t, motors j, k for driving the carriage and operating an oil pump m, respectively. The support f is carried on a plunger n which is lifted up to the level of ports p leading from the cylinder o to the pump-intake, gravity restoring the plunger when the motor k stops. With the carriage in starting position, a motor 4 is set in continuous operation and through reduction gearing and a tappet 7, intermittently energizes electromagnets x, x<1> over a switch 8. The electromagnets have pivoted armatures 9 with dead-centre retaining springs 10 and, when energized, close mercury switches v, v' which energize hot wires z, z<1> whereby, firstly, z' closes a switch w<1> to operate motor k to raise the support f clear of the bath b and then z closes switch w to energize the motor and drive the carriage c. At an appropriate position, trip pieces 11, 11<1>, Fig. 2, engage arms 13, 13' and open the switches v, v<1> to stop both motors, the support f lowering the articles into the bath. The arrangement of trip pieces 11 may be such that the carriage moves in stages or continuously across the bath, the trip piece 11<1> being of sufficient extent to hold v<1> open and prevent the motor k being energized every time switch 8 closes and causes energization of motor j. At the conclusion, support f is lifted clear and the carriage moves on to the next bath. The support f may alternatively be raised by rack-and-pinion mechanism and the motor cut out by a limit switch, a brake retaining the support in raised position.

Title: A colour television signal recording and reproducing system
Inventor: MATSUI KUNIO
IPC: H04N9/81
Filed: 1965-04-21
Abstract: 1,108,242. Colour television. YAOU ELECTRIC CO. Ltd. 21 April, 1965, No. 16719/65. Heading H4F. A line-sequential composite chrominance signal is obtained by combining at a matrix circuit the luminance with the colour-difference signals derived from a received N.T.S.C. signal, and applied either directly to a Lawrence tube having a single electron gun or by way of a video recorder which records the line-sequential signal or magnetic tape and reproduces the signal therefrom, the recorder being a narrowband (black and white type) video recorder since a line-sequential signal has a narrower band width than a simultaneous NTSC-type signal. The line-sequential signal includes the three primary colour components arranged in sequence and an instruction signal inserted on the back porch at intervals corresponding to one cycle of the changing three colour components, i.e. at every third horizontal scanning cycle. The instruction signal, which is used to control the voltage applied to the colour switching grid of the Lawrence tube and thus effect colour synchronization at the reproduced image, is inserted into the line-sequential composite chrominance signal in a manner similar to a burst signal by gating the output signal at a 1 megacycle oscillator with a pulse derived from the synchronizing signal components in the NTSC signal and having a cycle corresponding to three horizontal scanning cycles. The voltage applied to the colour switching grid has three steps in its waveform each step corresponding to one horizontal scanning period and is derived in a colour switching signal generator which has applied to it pulses of horizontal scanning frequency, derived from the synchronizing signals, and pulses having a cycle corresponding to three horizontal scanning cycles, derived from the instruction signal. The magnetic tape video recorder described is of known type the line sequential signal being frequency modulated before being applied to the rotating video head.

Title: Improvements in or relating to plug valves
IPC: F16K5/22
Filed: 1953-06-18
Abstract: 725,400. Valves. VOLPIN, A. S. June 18, 1953, No. 16855/53. Class 135. A rotary plug valve has an annular reservoir 10 for a sealing and lubricating substance which is fed to grooves 23, 24 in the face of the plug under pressure of the fluid in the line controlled by the valve. The plug, which is hollow, is rendered resilient by longitudinal slits 42 so that when closed that part of the plug exposed to . line pressure flexes to admit pressure to the reservoir. Pressure so admitted to one side of the reservoir is transmitted to the opposite side through a pair of movable barriers 29, and passages 31 convey the lubricating and sealing substance from each side of the reservoir to the vertical grooves 23 in the plug so that communication with the grooves is effected only in the fully closed and open positions of the plug. Two diametrically opposite charging connections 33 for lubricant are provided. A closure plug 11 has a groove 16 to receive sealing substance from the reservoir. A spindle with a notched flange 45 engaging projections 47 on the plug passes through a stuffing-box 53 and ball-bearing 57. A conical sealing face 61 on the stem engages with a face 60 in the housing when the spindle is permitted to rise by unscrewing a fitting 56 so that the stuffing-box or bearing 57 may be replaced whilst the valve is under pressure. A fitting 70 for the introduction of sealing material to the spindle is fitted. In a modification, a fusible washer is incorporated adjacent the bearing, so that in the event of fire the washer melts and allows the sealing face 61 on the stem to engage the face 60.

Abstract: 830,978. Winding thread. REINERS, W. June 1, 1956 [June 10, 1953], No. 16951/56. Class 120(2) A method of winding thread on a bobbin in an automatic bobbin changing winding machine, comprises presenting the leading thread end portion to a gripping device rotatable with the bobbin whereby the thread is automatically gripped upon commencement of rotation of the bobbin, releasing the gripped thread before the bobbin attains its normal winding speed and then deflecting the released thread end into the path of the thread leading to the bobbin so that the end becomes engaged by the thread and wound into the thread turns being formed on the bobbin. Fig. 2 shows a spindle head of an automatic winding machine. A hook 8 is provided at the forward end of a shaft 10 journalled in head 1 and a weight 9 is secured eccentrically on the rear end of said shaft and is formed with a projecting cam face 11. A spring 13 retains the weight 9 within a recess 14. In operation, during bobbin changing the thread is presented to the hook 8 and engaged therebehind. When the spindle head commences to rotate the thread is broken between the gripper 8 and a clamping device below the head 1 and at the same time a few turns are wound on the bobbin. When the speed of the spindle reaches a predetermined value the weight 9 swings out of recess 14 under centrifugal action, and, under the action of cam face 11 the shaft 10 and hook 8 move forwardly, i.e. to the right, so releasing the thread end. This end is then deflected by the base portion 3a of the bobbin outwardly so that the end is wound in with the next few turns wound on the bobbin. Shears may be provided for severing the thread instead of relying on it being broken by rotation of the bobbin. In other embodiments the shaft 10 and hook 8 are moved forwardly by electro-magnetic means; an external reciprocating member or an impeller means. In the latter case the air current from the impeller is used to blow the thread end into the path of the thread being wound on the bobbin.
