Abstract: 993,385. Reciprocating pumps and compressors. J. PASQUALI, Y. PEAUTHOIS, and M. DORDAIN. Dec. 2, 1963 [Dec. 11, 1962; June 10, 1963], No. 47426/63. Headings F1A and F1N. A pump or compressor comprises a reciprocating piston 14, Fig. 1, acting on an elastic pad 11 having a frusto-conical through passage communicating with inlet and delivery valves 6 and 7. Piston 14 is actuated by a lever 15 acting through a cam 19, stroke varying being effected by rotating cam 19 about a pin 16. In another embodiment, a spring-loaded plate assists pad 10 to effect the suction stroke, after the pump has been idle with the pad in a compressed condition. The edges of pad 10 are rounded to facilitate its deformation.

Title: Colour television camera
IPC: G03B33/00
Filed: 1973-10-11
Abstract: 1446449 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 Oct 1973 [14 Oct 1972] 47479/73 Heading H4F [Also in Division G2] A colour television camera viewing a scene 1 includes a pick-up tube 6, a source 39 of invisible radiation (or a source which emits both visible and invisible radiation and an appropriate filter 37), for example ultra violet or infra-red radiation, and two strip filters, one, 42, uniformly passing visible light from scene 1, but alternate strips of which pass less of the invisible radiation from source 39 than the intervening strips (to provide an index component in the tube output), and the other filter 44 uniformly passing the invisible radiation but being formed with overlapping red-blocking and blue-blocking stripes so that adjacent strips of filter 44 respectively pass cyan, green and yellow light. A filter layer 35 between prisms 31 and 33 removes from the radiation from scene 1 radiation corresponding in wavelength to that from source 39. The part of filter 44 near one edge is formed with a layer which blocks all visible light and the corresponding part of filter 42 has some of the radiation-blocking strips omitted to provide distinctive run-in-strips. The signal from the pick-up tube 6 is separated into a low-frequency component, a chrominance component, and an index component (due to source 39 and filter 42) by low-pass filter 51 and band-pass filters 52, 53 the chrominance component from band-pass filter 52 being demodulated at 58 with a signal at the same frequency which is derived from the index component from band-pass filter 53 via frequency divider 56 and frequency multiplier 57. The phase of operation of frequency divider 56 is controlled by the output of band-pass filter 55 which is derived in response to the run-in strips of filter 42, switch 54 being closed only when radiation passed by these run-in strips is being scanned. A second, luminance, pick-up tube may be provided.

Abstract: 1,173,318. Control systems for gas discharge flash lamps. TRW Inc. 26 Oct., 1966 [28 Oct., 1965], No. 48096/66. Heading H2H. [Also in Division H1] In the supply circuit for the gas discharge flash lamp 10 trigger pulses of adjustable duration and repetition rate from oscillator 28 are applied to the grid of thyratron 22, the firing of which causes the voltage across the section of coaxial cable 32 to be applied across, and to fire, the lamp. The lamp and thyratron return to the non-conducting condition when the coaxial line has discharged, the resistor 30 thereafter permitting the recharged coaxial line voltage to be applied again across the thyratron. The pulses applied to the lamp from the coaxial cable are of less than one microsecond duration, and the amplitude of these pulses, and the constituents of the lamp filling and their partial pressures, are chosen such that the duration of each of the pulses is approximately equal to the natural discharge time of the lamp, i.e. the time for decay to half intensity upon removal of the exciting stimulus.

Abstract: 1,256,254. Chamfering gear teeth; machine tool details. GLEASON WORKS. 1 Oct., 1969 [1 Oct., 1968], No. 48237/69. Headings B3B and B3L. A chamfering unit particularly for spiral bevel or hypoid gears comprises upper and lower centring and clamping assemblies 24, 22, a pair of chamfering assemblies 26, 28 for chamfering the toe and heel portions of the teeth of a gear piece 32 and an indexing assembly 30. The lower centring and clamping assembly (Fig. 4) comprises an hydraulic piston and cylinder unit 38, 40 the piston carrying a rotary centre 36 and being urged upwardly by a spring 66. The upper centring and clamping assembly (Fig. 5) includes two springs 132, 134 so arranged that with a workpiece held between the centres and with only the pressure of spring 66 urging the centre 36 upwards the upper centre is retracted a limited distance d 1  against the pressure of spring 132 only. Under this condition the workpiece is rotatable for indexing. When hydraulic pressure is applied to the piston 38 of the lower assembly 22 further retraction d 2  of the centre 148 takes place against the combined action of springs 132, 134 and the workpiece is firmly clamped against a serrated lower face 144 of the upper clamping assembly 24. A rod 112 extends through the upper assembly and carries limit switches at its upper end for controlling parts of the chamfering cycle. Each chamfering assembly (Fig. 1) comprises a reciprocable mount 174 operable by hydraulic pressure to bring the chamfering head adjacent a workpiece. The chamfering head is adjustable vertically and horizontally and angularly about the axis of the mount 174 by bracket means 176 The chamfering tool 268 is adjustably mounted at the end of a piston member 202 adapted to be reciprocated linearly by hydraulic pressure. Air pressure outlet ports 242, 252 are covered at the ends of the strokes to initiate the next phase of cycle through suitable control equipment. The indexing assembly which operates between each chamfering stroke comprises a spring loaded finger 538 reciprocated vertically by hydraulic piston 412. The stroke of the finger is suitably adjusted to provide the required degree of indexing which results from the finger moving along the spiral tooth space. When the workpiece is clamped between the upper and lower assemblies the finger rides over the teeth being displaced into its mounting against the force of spring 542. Cycle control limit switches B, C are actuated in co-operation with the movements of the indexing piston. Scales are provided to enable accurate adjustment to be made of the positions of the chamfering heads and index finger and the unit may be made to operate in conjunction with the feed movements of a workpiece conveyer 34.

Abstract: 1306130 Colour television NIPPON HOSO KYORAI 16 Oct 1970 [10 Nov 1969 (2)] 49213/70 Heading H4F A modification of the system described in Specification 1,270,552 for conversion of television signals from 625/50 standard (PAL or SECAM (Registered Trade Mark)) to 525/60 NTSC, or vice-versa permits frame frequencies differing from a strict 50/60 ratio. In Fig. 1 the functional units in the right-hand broken-line box are generally as disclosed in Specification 1,270,552, the action being that after processing as necessary to convert to SECAM standard a line interpolator modifies the content of lines adjacent those to be deleted to minimize visible picture distortion, a line compensator slightly reduces the line length (period) to that of the NTSC standard, a line converter deletes every sixth line after the first twelve of the 312À5 lines of the field, a field setter precompensates for interlace of inserted extra fields, and a field converter inserts extra fields by repetition of every fifth field. A #t compensator corrects for various timing errors and a field interpolator corrects for jitter due to the added field inverting the sequence of interlaced fields. The luminance and chrominance signals are then separated and processed to NTSC standards. According to the invention a non-locked control device receiving P and Q frame signals acts to pair input and output frames for conversion in such a way that fifty lines can be deleted from the incoming frame without this reduction in frame time rendering completion of the output frame impossible. For this purpose the P and Q signals are continuously monitored and the time difference processed arithmetically to load line and frame counters which control the deletion of lines and insertion of frames. The rate of insertion of frames is controlled by the relative P and Q timing so as to vary from its nominal 1:5 rate. Schematic circuit diagrams and timing diagrams illustrate the various stages of the conversion process, and of a converse process for deletion of fields and interpolation of lines for the reverse conversion. A small computer may be used to control the conversion timing.
