Abstract: 1,228,753. Compression moulding; hydraulic presses. SAMCO STRONG Ltd. 24 May, 1968 [24 May, 1967], No. 24030/67. Headings B5A and B5F. A press suitable for the production of duplicate printing plates from thermoplastic material, consists of a lower set of heated platens and an upper set of cooled platens, the workpiece first being precompressed to an oversized blank between the lower set of platens and then compressed to the desired final shape between the upper set of platens, during which compression the blank is cooled and set in its final shape. In the embodiment shown in the Figure the uppermost platen 64 of the upper set of platens is fixed, the middle platens 42 and 38 of each set are connected by heat-insulating plate 44 and are movable by means of cylinder 60, and the lowermost platen 28 of the lower set is movable by means of a ram 20. In operation, with the platens as shown in the Figure, the workpiece, sandwiched between a matrix and a carrier plate, is transferred from a work-table at level x-x on to platen 28 which is then raised, first against plate 38 under light pressure to heat the workpiece, and then under heavy pressure to close the press and precompress the workpiece. After the pre-compression the platens are allowed to fall under gravity and the dash-pot control of the cylinder 60 and ram 70 to their original positions whence the workpiece is transferred back to the work-table. The platens are then allowed to fall further until platen 42 reaches the level of the work-table, the workpiece then being transferred on to the platen and the platens re-raised to effect the final compression and cooling.

Abstract: 1,233,594. Television tuning indicators; modifying waveforms. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 24 May, 1968 [18 Sept., 1967; 26 Feb., 1968 (3)], No. 25054/68. Headings H3Q and H3T. A tuning indicator circuit for displaying a bar on a television picture tube comprises means for obtaining a ramp-function waveform from the horizontal or vertical deflection circuit, slicing this at levels depending on a voltage which indicates the state of tuning, generating a pulse of width corresponding to the sloping part of the sliced waveform, and applying this pulse to the picture tube. In Fig. 3 the sound or video I.F. signal is applied at G to a limiter valve V3 and then rectified by D4 and smoothed to eliminate the modulation, so that the base of transistor Tr receives a voltage which is maximum negative at correct tuning and decreases to zero for progressive mistuning. Potentiometer R16 is adjusted so that the transistor just saturates on correct tuning. A sawtooth voltage from the horizontal deflection circuit is applied at A and converted into a linear ramp function by R1, C1 and C2. The portion of the sawtooth that is more positive than the emitter voltage of Tr is clipped by conduction of diode D1 and the portion that is more negative than the emitter is clipped by conduction of diode D2. At correct tuning, when the transistor is saturated, only a small portion is left at the centre of the sawtooth, but more and more is left as the conduction of the transistor is reduced due to progressive mistuning of the receiver. Any shift of the mean level of the residual waveform is prevented by a clamping diode D5. The waveform is differentiated by C3 and R6, the negative spike being removed by diode D3, and the remainder amplified by valves V1 and V2. The output F is taken to the grid of one of the colourdifference amplifiers in a colour receiver (Fig. 5, not shown) to produce a coloured bar in the centre of the tube. The rest of the tube then appears in the complementary colour owing to the shift in the zero level of the other colourdifference amplifiers. Alternatively the output F can be applied to the X and Z demodulators or to a video amplifier (colour or black-andwhite receiver). The valve amplifiers V1 and V2 may be replaced by transistors (Fig. 7, not shown). Alternatively, a bi-stable circuit may be used to give two bars which coincide at the correct tuning point.

Abstract: 1,233,648. Electron-beam recording and playback. AMPEX CORP. 27 June, 1969 [17 July, 1968], No. 32592/69. Heading G5R. A system for effecting timebase stabilization and correction of signals played back from a recording medium, e.g. a film, by a scanning electron beam comprises means for obtaining from the recording medium a pilot signal of selected frequency, means for generating a plurality of reference signals of selected frequencies, one of the reference signals being a quadrature reference signal, means responsive to one of the reference signals and the pilot signal to provide an in-phase output signal indicative of the accuracy and direction of the scanning beam and a quadrature output signal indicative of the playback raster size and centring errors, and means responsive to the quadrature output signal to provide, for sweep circuits controlling the scanning beam, error signals controlling the raster size and centring of the scanning beam. As described, a crystal-controlled pilot signal of selected frequency is recorded on the film. During playback, the same crystal and divider used in recording provide a reference frequency equal to the pilot frequency. This reference frequency is fed directly to an in-phase multiplier and also via a 90 degree phase shifter to a quadrature multiplier. The pilot reproduced from the film is fed to the in-phase and quadrature multipliers. The output of the in-phase multiplier is a positive D.C. signal if the lines are properly tracked in the forward direction. The quadrature reference frequency is multiplied by the line repetition frequency and the output of this multiplier is multiplied by the pilot reproduced from the film. The output from this multiplier contains signals representative of the size error. The quadrature reference frequency is also multiplied by one-half the line repetition frequency and the output of this multiplier is multiplied by the pilot reproduced from the film. The output from this multiplier contains signals representative of the centring error.
