Patent GB-1424813-A (GB)
Title: Synchronization separator circuits
IPC: H04N5/08
Filed: 1973-03-09
Abstract: 1424813 Synchronization separator HITACHI Ltd 9 March 1973 [10 March 1972] 11530/73 Heading H4F A synchronization separator comprises a comparator circuit (e.g. differential amplifier T 16 , T 17 ) the video signal being supplied to its inputs via a D.C. level shifting circuit and a peak value detector circuit. As shown the video signal is supplied directly to the base of transistor T 17  and via a D.C. level shifting circuit T 11 -T 15 , R 11 -R 14 ) and a peak value detecting circuit (T 15 , C 12 ) to the base of transistor T 16 . The arrangement enables the synchronization separating level difference, i.e. the difference between the peak level of the video signal and the level at which the video signal is clipped to be made small so that synchronization is not lost when the synchronizing component of a video signal is compressed. Horizontal and vertical sync pulses are separated from the video signal. The circuit may be formed as an IC and its operation is stable with respect to temperature change. A noise suppressor filter comprising transistor (diode) T 14 , resistors R 15  and R 16  and capacitor C 11  may be connected as shown, so that signals having their noise content suppressed may be fed into the AGC circuit of a television receiver. In a further embodiment (Fig. 5, not shown) both inputs to the differential amplifier are level shifted and one is also peak detected.

Title: Improvements in or relating to seals and to oscillatory vane actuators incorporating the same
Inventor: RUMSEY ROLLIN DOUGLAS
IPC: F16J15/54
Filed: 1965-03-22
Abstract: 1,096,266. Seals. HOUDAILLE INDUS TRIES Inc. March 22, 1965, No. 12058/65. Heading F2B. [Also in Division F1] A seal member in an oscillatory vane actuator to seal against leakage between the vane hub and the housing end cover on the one hand and between the housing end cover and the actuator shaft on the other hand, comprises a counterbore 15, Fig. 1, in the or either end cover 11 of diameter equal to that of the vane hub 8 housing an annular sealing member 20 having shoulder portions 21, 22 and a thinner interconnecting resilient portion 23, with bores 24 therethrough connecting opposite sides of the sealing member. The sealing member 20 in its unstressed condition is of greater extent both axially and radially than the annulus formed between the shaft 7 and counterbore 15 so that when it is pressed into the annulus the portion 23 sealingly thrusts the portion 21 against the base 17 of the counterbore and the shaft 7 and the portion 22 against the axial face 18 of the hub 8 and the counterbore 15. Should leakage occur past seal 30 and 0-ring sealing member 31 surrounding the fixed abutment 13 from the working chamber at higher pressure to the working chamber, at lower pressure due, e.g., the slight deformation of the end covers under excessive high pressure, the pressure will be relieved into the counterbore 15 to pass through the bores 24 to both sides of the sealing member 20 to thus enhance the seal between the shoulder 21, and the base 17 and shaft 7. In a modification, the interconnecting resilient portion 23<SP>1</SP>, Fig. 3, may be made separate from and of different material to the shoulder portions 21<SP>1</SP>, 22<SP>1</SP>. The shoulder portions may be made of tetrafluoroethylene resin reinforced with glass fibre and the resilient portion of synthetic rubber. The resilient portion 23<SP>1</SP> may be initially of square section, the shoulder portion 22<SP>1</SP> triangular and the shoulder portion 21<SP>1</SP> L-shaped with a tapered surface 35 against which the portion 23<SP>1</SP> tends to slide. Instead of being square the resilient portion 23<SP>1</SP> may be of round cross-section.

Flexible p i p e s , making.-In a machine for converting strip rubber into tubular form for use as air-tubes for tyres, means are provided for cleaning the strip of chalk, &c., applying cement to the skived edges, partially drying the applied cement, folding the strip to form a lap-joint, and finally rolling to the finished flat tubular form. The rubber strip is fed from. a roll 39 on to a travelling conveyer-band 20 from which it is led over guide-rolls 45, 46, 47. During this stage, brushes 48, 51, partially immersed in benzene &c. baths 50, 57 respectively, clean the skived edges at opposite sides of the strip, which is then guided by fingers 59 on to the conveyer, and thus to the cement-applying disks 67, 71. At this stage, a strap 30, travelling with the band 20, is deflected between this and the rubber strip. The latter now passes through the heated drying- ovens 77 (the effective operation of which can be regulated) to the folding-device 104 in which the cemented edges are lapped as shown in Fig. 11. The flattened tube, to which the valve-tabs may now be attached, then passes under a pressing- roll 88, on to the exposed rearward portion of the convever from which it is fed on to a terminal conveyer 106 where it is divided into lengths suitable for air-tubes. The main conveyer 20 and the various operating-unite, as well as a brush 121 for cleaning the conveyer 20, are driven from a motor 112, the conveyer 106 being driven from a separate motor 126.
