Abstract: 972,311. Hydraulic shock-absorbers. GIRLING Ltd. Oct. 22, 1962 [Oct. 31, 1961], No. 38838/61. Heading F2S. An hydraulic shock-absorber, comprising a piston 10 carried on a piston-rod 12 acting in a cylinder 11 and having a transfer passage or passages 22 which co-operates, or co-operate, with a gland 13 to provide an hydraulic stop, is characterized in that each transfer passage, in the direction of damped flow, is controlled by a one-way valve 26 having a closure member in the form of a flexing-shim. The piston 10, having a skirt 17, is secured to the end of the rod 12 between a collar 19, which abuts a shoulder 15 formed by a reduced end portion 14 of the rod 12, arid a flanged sleeve nut 20 the passage 22, extending obliquely through the rod 12. The upper end of the passage 22 opens, at 23, into the cylinder space, between the piston 10 and the gland 13, the lower end communicating, at 24, with a gallery 21 within an enlarged bore in the collar 19. The gallery 21 communicates with a number of passages 25 which extend axially through the piston 10 and open into an annular groove 28 closed by the one-way valve 26. The latter comprises two shims, or sheetmetal rings, 27, the inner edges of which are clamped between the piston 10 and the nut 20, and the outer edges are urged against the piston 10 by a helical spring 29 constrained between the flange 31 of the nut 20 and an L-aection thrust washer 30. A second set of axial passages 32, controlled by a ring valve 34 loaded by a spring washer 35, allow transfer of fluid in the reverse direction. In a modification a passage 22, blind at its upper and lower ends, is located axially of the rod 12 and has radial branch ducts which communicate respectively with the cylinder space between the piston 10 and the gland 13 and with the gallery 21. The nut 20 may be secured to the rod 12 by welding.

Title: Improvements in or relating to television systems
Inventor: MARCH ROY COLLINS
IPC: H04N5/073
Filed: 1958-12-05
Abstract: 869,708. Television systems. MARCONIS WIRELESS TELEGRAPH CO. Ltd. Sept. 23, 1959 [Dec. 5, 1958], No. 39368/58. Class 40(5) In a television field phase controlling arrangement for automatically controlling the phase of the field pulses in a locally produced synchronizing waveform including field and line pulses to be in step with the field pulses in a controlling externally produced waveform also including field and line pulses, triggering pulses at line frequency or a multiple thereof, synchronized by the externally produced line pulses, are fed to a counter chain to provide a field pulse in the locally produced waveform each time a predetermined number of pulses has been counted in the counter chain, the number of pulses being applied to the counter chain being changed, i.e. cut off, or added to, in response to the difference in phase between a pair of pulses initiated by the field pulses in the respective waveforms. The synchronized trigger pulses at twice line frequency produced in a generator 1, Fig. 1, are applied via 1 in 405 counter 3, and 1 in 2 counter 5, to waveform generator 4 in which waveform A, Fig. 4, comprising field and line pulses is produced. A gate 2 in the feed to counter 3 is controlled to shift the position of the field pulses in response to any phase difference in the outputs from field pulse integrators 7, 7<SP>1</SP>, the former being fed through a clipping amplifier 6 and the latter from the external waveform applied at terminal T 1 . In the units 8, 8<SP>1</SP>, Fig. 1, trigger pulses applied at terminals T 3  are applied to the grid V 2  of a multivibrator V 2 , V 3  when the output of a differentiating circuit C 1  R 1  to which the pulse from integrator 7 is applied is sufficient to cut-off rectifiers D 1  D 2 . The first triggering pulse is passed at substantially full output but succeeding pulses are relatively ineffective and the output pulse as shown at D, Fig. 4, has a length determined by the circuit characteristics and by an input of low amplitude trigger pulses at terminal T 4 . The low amplitude pulses are delayed to prevent corrective action when the field pulses are only slightly out of phase. The outputs from units 8, 8<SP>1</SP>, are applied over terminals T 10 , T 9 , Fig. 3, to a monostable multivibrator V 5 , V 6 , the former initiates a corrective pulse for operating gate 2 and is terminated in an interval determined by the circuit time constants or by the trailing edge of the corresponding pulse from unit 8 the former being arranged to cancel an even number of pulses. In a modification described with reference to Figs. 5, 6, 7 (not shown) the out-of-phase condition automatically reduces the number of output pulses from unit 2 or adds extra pulses whichever is quicker. Delayed trigger pulses are gated to provide the extra pulses, a transistor multivibrator being provided for controlling the gating.

The belt 116 is tensioned around pulleys 118, 119 by a pivoted, counterbalanced arm 121. The recorder unit 1 includes two coaxial spools 21, 22 carrying a six-track tape 23. Nylon tape-guide rollers 24-26 are barrel-shaped and are inclined to the base 14 of the tape deck 5. Four further rollers 44 guide the tape 23 across three six-track heads 41, 42, 43 which successively erase, record and monitor signals. The tape 23 is driven by a pinch roller 59 biased by a spring 63 against a sleeve (75), Fig. 3 (not shown), on the drive shaft 61. Each end of the tape 23 has an aluminium strip which shorts two gold brushes 102. This causes the tape drive to be reversed and the functions of heads 41 and 43 to be interchanged, and switches all three heads to the next of the six tape tracks. This is achieved by a six-position rotary switch 107 which also provides an indication of which track is in use. A potentiometric device 78-89 indicates the tape footage or position. A circuit board 105 mounts a preamplifier for the monitor signals. The tape 23 is tensioned by a spring (97), Fig. 3 (not shown) which has one end attached to spool 21 and the other to a shaft 91 to which the spool 22 is fixed. Each tape end is connected to its spool by a projection (124), Fig. 8 (not shown) which co-operates with an aperture (125) in the spool.
