Title: Transmission system for the transmission of characters
IPC: H04N1/413
Filed: 1969-12-19
Abstract: 1298839 Character transmission system PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Dec 1969 [24 Dec 1968] 61961/69 Heading H4F The video signal, corresponding to the scanning by camera 1 of a character, is passed through a threshold circuit 3 and then through a digital-to-analogue converter 8, comprising a sampler circuit 9 and a sawtooth generator 10, before being applied to wire 14 for transmission, the field sync. pulses from generator 5 being transmitted on wire 16. At the receiver the field sync. pulses are converted 18<SP>1</SP> into sawtooth signals of field frequency and applied to one pair of deflection plates of display CRT 19 and the video signal whose amplitude varies in a step-like manner is applied to the other deflection plates. Vertical scanning is employed in the embodiments described, for example in the character of Fig. 2 is scanned, e.g. scan lines I-VI, the resulting signal applied to the vertical plates of the display tube is shown in Fig. 3d, in which waveforms 3a, 3b and 3c represent respectively the outputs of the camera, threshold circuit 3 and sawtooth generator 10. The video signal may be stored 23, e.g. on a magnetic tape or disc, and played back by means of switches S1 and S2. Also under control of a square-wave signal 25 from an astable multivibrator 26 a signal from the camera and a signal from the storage device 23 may alternately be displayed one above the other, signal 25 in addition operating switch S1 which applies a switching voltage to the vertical deflection plates. This arrangement may be used for comparison of signatures. In a second embodiment (Figs. 4 and 5, not shown), the bandwidth of the transmitted video signal is reduced by including a transition counter and a gating circuit between the threshold circuit and the digital-to-analogue converter, the arrangement being such that only pulses corresponding to the nth black-to-white transition of each line are transmitted during the nth field period, the last black-to-white transition of each line being transmitted in the (n+ 1)th field period, e.g. as described the first, second and third transitions in each line are respectively transmitted in the first, second and third fields and the last transition in each line is transmitted in the fourth field, any intermediate transitions being omitted. The display CRT at the receiver is arranged to have long persistence. Since the deflection of the electron beam in the display tube to the positions of the blackto-white transitions is not effected infinitely quickly the beam is preferably suppressed during these deflections.

[Also in Groups XIX and XL (b)] The profile or contour of a surface is determined by means of a carriage movable along a reference axis and a feeler movably mounted on the carriage so as to be pivoted in a plane by the contour, this pivoted movement being detected and the feeler restored to its angular position with respect to the axis either manually or automatically. As described, the apparatus is applied to measuring the internal diameter of a wire drawing die mounted in a chuck (not shown). The feeler 4a is mounted on the carriage 9 which is advanced along parallel rods by a micrometer 10, the carriage being held against the micrometer tam 11 by a spring 12. The feeler may be raised vertically by a further micrometer 19 which lifts a rod 13 on the end of a bell crank lever 18. The rod slides on four polished balls against which it is held by a leaf spring 16. The rod may be rotated about its own axis for adjustment purposes. The feeler itself is mounted in a head 32 so as to be capable of pivoting in the vertical plane. The feeler end is slightly heavy and rests against the bottom of the profile under examination, or alternatively a counter weight 30 will make it rest against the top of the profile. Light from a source at the end of a container 55 is reflected from a mirror 6 mounted at the rear of the feeler and is split to two photo-cells by a stainless steel prism 34. These photo-cells are incorporated in an A.C. bridge circuit, unbalance of which in one direction or the other is used to control a phase sensitive servo-motor 36 which through gearing 25, 26 raises rod 13 to rebalance the circuit. Initially the feeler rests on a. part of the profile. The carriage is then advanced by a motor driving through a micrometer 10. If the profile is other than parallel to the axis the photo-cell will be unbalanced and servo-motor 36 will run to rebalance the illumination on each cell and at the same time to move through gearing a marker parallel to the axis of a drum. The drum is rotated by the same motor which advances the carriage.

Title: Hydraulic Line Coupling Arrangements
IPC: B60T17/04
Filed: 1978-11-06
Abstract: A coupling arrangement to couple the hydraulic brake system of one vehicle to that of a trailer comprises a casing within which two displaceable members 17, 19 are slidably arranged. Pressure fluid of the first fluid pressure system acts on one member and fluid pressure of the second fluid pressure system acts on the other member and a pressure difference between the two systems is reduced by mutual displacement of the two members. The casing can be split into two parts, 11, 12 each containing a displaceable member, and a resilient member 21, 22 acts upon each displaceable member to urge that member to the position of maximum volume for its respective pressure system. Thus, when the coupling is split, the resilient means expand both fluid pressure systems, where necessary drawing additional fluid from a system reservoir, to permit the two systems to operate independently. <IMAGE>
