Title: Signal transmission system in data processing devices
IPC: G11C11/06
Filed: 1966-06-06
Abstract: 1,145,916. Circuit assemblies. SCIENTIFIC DATA SYSTEMS Inc. 6 June, 1966 [9 June, 1965], No. 25161/66. Heading H1R. In a data processing system the wires interconnecting the active and passive circuit elements run in the proximity of one or several conductive plates to which the elements are also connected. In the embodiment of Fig. 1 a frame 10 receives a plurality of circuit modules 11, 12, 13 each module comprising a printed circuit network supporting a plurality of circuit elements interconnected to form a logic circuit module. Connector pins of the modules traverse in pairs small slots in the electrically conductive plate 25. Pins 15 and 18 of module 11, pin 16 of module 12 and pins 17 and 19 of module 13 are connected by short connecting wires to the plate 25 which is at ground or reference potential. The modules are interconnected by wires 26, 27, 28 connected to the appropriate pins and insulated from each other. Since the signals transmitted between the modules have a high pulse rate frequency the connections made constitute high frequency transmission lines. A voltage source for driving the modules, Fig. 2 (not shown), has one terminal connected to the ground plate 25 and its other terminal connected via feeder cables to the various pins of the modules. The signal transmission characteristics from module to module can be further improved by including a conducting plate 45 in each module, Fig. 3. Each module comprises an insulating ground plate 40 carrying on one side elements 41, 42, 43 the connecting wires of which are connected to etched conductors 44. The plate 45 is connected to the etched conductors 44 through holes in the ground plate 40 at points where ground potential is to be applied by means of pins such as 15 of Fig. 1. The ground plate 25 and conducting plate 45 have an effective capacitance relative to the cable connections which offsets or balances any inductance provided by curvatures in the cables and/or etchings and also act as shields.

Title: Narrow band television system
IPC: H04N7/12
Filed: 1973-05-25
Abstract: 1413637 Television GENERAL ELECTRIC CO 25 May 1973 [8 June 1972] 25241/73 Heading H4F Television signal bandwidth reduction system for line transmission utilizes a pseudo-random N-fold dot sequential interlaced sampling in which for example the same particular picture element (video signal dot sample) is selected from every successive group of 16 dot samples in each line scan, 16 of these samples being selected from each line scan, and the sample selected in successive line scans is varied in a pseudo-random manner which is such that 16 video signal frames are required before one complete frame of video signal information has been sampled for transmission. In Fig. 1 a video signal from a television camera is supplied to input 10 and the separated sync. signals are fed to sampling oscillator 16 operating at 252 KHz, i.e. 16 times the line frequency, whose output is divided by 16 in binary counter 20 and supplied to a sampling counter 26 which controls a multiplexer 28 so that it changes at line frequency the terminal 32 to which the sampling pulses from oscillator (supplied, via delay line driver 30 which forms  Ásec. pulses, to input 29) are connected, these terminals 32 being connected in a pseudo-random manner to taps on a a delay line 36 whose total delay time is substantially equal totheperiodofthe output of oscillator 16. The resulting sampling pulses from the output of delay line 37 are used to gate 40 the video signal, the resulting dot samples being fed via a holding circuit 44, which stretches the dot samples, to a mixer 54 in which the sync. signals and reset pulses R are added before transmission. The reset pulses R are necessary to ensure that the sampling sequence is duplicated exactly at the receiver (Fig. 2, not shown) since arbitrarily resetting the sampling counter would interfere with the pseudo-randomness of the sampling programme (it should be noted that the transmitted dot samples have been stretched in holding circuit 44 to occupy a time period of about 16 dot samples). The reset pulses R are derived by dividing by 16 the rate of the vert. sync. signal in counter 46 and then, halving it in counter 48 (i.e. 32 slow scan fields are necessary for one complete frame of information to be transmitted the scanning system employing line interlacing). Each reset pulse at the output of counter generator 52 is approx 0À3 milliseconds long with its leading edge about 2 milliseconds after the leading edge of the vertical sync. signal from separator 12. Sampling counter 26 is preferably a reversible counter which counts forwards or backwards depending upon which of two control terminals U and D is excited in response to an up-down binary counter 64, and is arranged so that during the first 16 fields it counts forwards and during the next 16 fields backwards. This increases the apparent randomness of the sampling.

IPC: B29C48/08
Filed: 1967-06-01
Abstract: 1,191,654. Coating and coating apparatus. GLAVERBEL. 1 June, 1967 [1 Aug., 1966], No. 25419/67. Headings B2K and B2L. A liquid is applied to a surface by discharging it downwardly from a dispenser as a steadily flowing film, while the dispenser and surface are relatively displaced, the volume rate of descent of the liquid being such as to maintain at the bottom of the descent path a quantity of liquid which flows over the surface in the direction in which coating proceeds. Initially a bead may be struck between the dispenser and surface and the relative distance then increased to too great an amount to maintain a bead by surface tension. The liquid may first be applied to an auxiliary surface flush with the surface to be coated. The flow of liquid may initially be assisted by gas under pressure. The surface may be of glass, metal, plastics or ceramic in sheet form. A further coating may be applied by the same method and the compositions of the successive coatings may react to form a desired deposit. In the apparatus shown a curved rail 3 supports a trough 4 above a glass sheet 5 on a support 1. The liquid flows from a reservoir 6 through a pipe 7 and a valve 9 into the trough to maintain a constant level therein. At commencement of operations a slit 10 at the bottom of the trough is against the strip 2. It is then raised from the surface by movement along the rail and liquid begins to flow. Once the desired height of the dispense is reached it is moved at a fixed distance from the glass sheet.
