Title: Pal system colour video signal reproducing system
IPC: G11B20/02
Filed: 1975-10-31
Abstract: 1530448 Colour television NIPPON VICTOR KK 31 Oct 1975 [5 Nov 1974] 45560/75 Heading H4F In slow motion replay of a PAL video signal, recorded on tape (Fig. 2, not shown) so that chroma signals of different kinds (i.e. wherein the phase alternating sub-carrier of one signal is phase reversed with respect to that of the other signal) are aligned side by side in adjacent tracks, the scanning head does not follow a single track, but passes from one to the next and as it does so the phase of one of the sub-carriers being detected is reversed, which leads to loss of colour in the reproduced picture. This is overcome by detecting when the phase alternating subcarrier has the wrong phase (by generating a half-line frequency signal, from the line sync., at the output of 43 and phase comparing it at 52 with a signal resulting from comparison at 50 of the colour burst phase with a reference 4À43 MHz signal from oscillator 63, the normal half-line periodicity of the latter being interrupted when said phase alternating subcarrier has the wrong phase) and substituting at switch 46, during these times, a signal which has the same frequency as the reproduced chroma signal but which has been phase corrected at 47. Alternatively (Figs. 6, 8, not shown) the substitute signal may be derived from the reproduced signal by a one line delay. Also described (Fig. 3, not shown) is a system wherein the recorded signal comprises a frequency modulated luminance signal and a chroma signal having a subcarrier frequency below that of the luminance signal.

Abstract: 1,240,618. Steering wheels. SOC. AUTOVEIL. 24 Sept., 1969 [24 Sept., 1968], No. 47062/69. Heading B7J. [Also in Division G1] In a safety device for use in driving a motor vehicle, a high resistance wire 4, i.e. of the order of 100 K #, is mounted on the steering wheel 1 in the form of a plurality of loops coaxial with the steering wheel, and is connected to a circuit for providing an alarm when the current in the wire drops below a predetermined value. In use the wire is shunted by the driver's hands, relaxation in the driver's muscles, due to fatigue, causing a change of conductivity of the hands and thus a drop in current through the wire. As shown, the wire 4 forms one arm of a bridge circuit, and when the current in this arm AB of the circuit drops below a predetermined value (set by rheostat Rh), a transistor T 1  conducts and causes a transistor T 3  to conduct and trigger the alarm V 1  which may be visual or acoustic. Application of a finger to the wire is sufficient to stop the alarm. A further reduction of the current may cause the vehicle braking system to be actuated. Alternatively, if the current remains low for a sufficient period of time after triggering of the first signal, the engine ignition may be cut or the brakes actuated.

A cassette 1 containing film 2 of the type in which a light sensitive sheet 4 and an image receiving sheet (16) Fig. 2, (not shown), are hinged to a carrier strip 3 either side of a liquid container (18) is inserted into a camera having its back hinged open and the carrier strip 3 led across an exposure aperture 5, over rollers 8, 9 and through an opening 13 until a marking on the strip 3 is in alignment with the opening 13. A transport lock (not shown) is set and the camera back closed, thereby bringing a spring backed pressure plate 6 and a roller 10 into contact with the strip which is pulled out until stopped by the transport lock. After exposure, the transport lock is released and the strip 3 pulled out, the exposed sheet 4 being guided into a chamber 7 by the roller 8. When the hinge of sheet 4 passes the roller 8, the sheet 4 is drawn out of the chamber 7 so as to overlie the image receiving sheet, the roller 8 and a projection of the camera back rupturing the liquid container (18). The members 8-10 and the projection serve to spread the liquid evenly between the two sheets. When these sheets have been pulled out, the transport lock stops further movement of the strip 3, from which the processed sheets can be torn off. The carrier strip 3 may be of image receiving material, in which case the hinged sheets (16) are not present.

Abstract: 1,076,290. Two-part couplings. AMP Inc. Nov. 18, 1965 [Dec. 14, 1964], No. 48981/65. Heading H2E. A high-voltage electrical connector comprises mating plug and socket members, the insulating body of the plug member being made of a more flexible material than that of the socket member, and the dimensions of the bodies being such that when the end of the plug member initially engages the bottom of the socket member, there is a clearance between the two bodies. The plug member is subsequently expanded to make full surface to surface contact with the socket wall by screwing nut 22, rotatably attached to the plug member, on to external screw threads 12a on the socket member. As the screw nut is tightened, air and insulating grease are expelled from between the members into a space between threads 22a and the top of the body 28 of the plug member. The preferred angle of taper B of the plug member is 6À5  0À5 degrees, and that of the socket is 8  0À5 degrees. The plug and socket members may have a constant taper or a taper which increases progressively as shown by the dotted lines in Fig. 2. The socket body may comprise a bushing 12 of fired ceramic or glass secured to a mounting ring 14, and an internal socket body 19 also of ceramic or glass, or the bushing and internal body may be formed integrally. The plug member is of synthetic rubber treated with silicone. For use at relatively low voltages, the socket body and flange may be formed integrally of epoxy resin into which the contact 16 is moulded. In this ease the screw ring 22 may also be of epoxy resin.

When correcting mistakes made in the original sound record on a tape recorder 1 synchronized with a film projector 4, bias current is supplied to the record head after current is supplied to the erase head, the delay in unit 3 being equal to the travel time of the tape between the two heads, and both currents pass through a unit 2 which reduces the rate of rise of current and thereby prevents transients producing noise on the tape. The sound mixing amplifier 5 receives inputs from the synchronized tape recorders 7-9 and two non-synchronized tape recorders 10 and 11. When using only the synchronized recorders, all units are returned to a position before the mistake occurred and restarted with the record head short-circuited over a lead a. At the desired point the switch K is closed to energize the erase head, remove the shortcircuit from the record head, and, after the required delay, supply bias to the second head. When the non-synchronous recorders are used a second recording must be made of the whole scene. In a newsreel, for example, separate scenes may be prefaced by cue signals in the projector and by the sound of a gong 6, and when re-recording the cue signal may actuate the gong 6 and the switch K.
