Title: Improvements in and relating to television cameras
IPC: H04N5/217
Filed: 1964-12-16
Abstract: 1,066,548. Television; cathode-ray tube circuits. M. GRUNDIG. Dec. 16, 1964 [Jan. 14, 1964], No. 51231/64. Headings H4F and H4T.  The output capacity of a television pick-up tube of the vidicon type due to the proximity to the signal electrode 2 of the grid mesh electrode 11 and of other elements such as the anode 15 is effectively reduced by supplying to at least electrodes 11 and/or 15 a compensation potential comprising a portion of the signal output of an amplifier 4, 5, 6 having the video signal output from electrode 2 as input. The required signal may be derived from a tapped potentiometer 20 or from point 21 in the feedback circuit. By thus reducing the effective input capacity of the amplifier the signal-tonoise ratio is improved. The amplifier, which comprises a printed-circuit board arranged in annular form around the electrode 2, is provided with a shield 14 held at the compensation potential by a connection at point 13. It is also advantageous to arrange for the deflection coils 23 and/or the focusing coils 24 to be operated at this potential.

Title: Gallium arsenide photocathode
IPC: H01J1/34
Filed: 1975-12-16
Abstract: 1535061 Making gallium arsenide photocathodes STANDARD TELEPHONES & CABLES Ltd 16 Dec 1975 51426/75 Heading HID A gallium arsenide field emission photocathode is made by bombarding a layer of p-type GaAs with protons to form a grid pattern of semiinsulating material 24 therein, and preferentially etching the material 24 by a cathodic inhibition process in a chemical etching solution with the p-type material 25 negatively electrically biased, whereby the GaAs layer is left with a figured surface having an array of field emission points. The proton bombardment may be done using a finely focused beam to write in the grid pattern, or, as shown, using a mask which includes a partly etched gold layer 23 above the GaAs layer. Initially the GaAs layer is epitaxially grown on a temporary substrate of semiconductor, e.g. also GaAs, and the layer is then bonded to a permanent substrate 15 of glass, by heating the components and pressing them together. The semiconductor substrate is then removed by etching; this may be a cathodic inhibition process as previously defined, if the substrate is semi-insulating; or, if the substrate is p-type, an anodic electrochemical etching process may be used, either in conjunction with monitoring of the optical transmission and thereby the thickness of the material to determine when to stop etching, or using an n-type blocking layer to stop the etch, which layer is then removed by chemical etching; the GaAs layer is thus exposed ready for the proton bombardment.

Title: Material stitching apparatus
IPC: D05B39/00
Filed: 1970-10-29
Abstract: 1371061 Sewing W J CLARKSON Ltd 26 Oct 1971 [29 Oct 1970] 51443/70 Heading D1G A work holding template 1 has a lower plate 2 formed with a continuous guide track 3 engaging a guiding peg 3a secured to the throat or needle plate of a sewing machine. The guide has a hole and a slot through it giving clearance for a needle and a knife respectively. Two top plates 4, 5 are hinged to the lower plate, and the template is moved by a roller 19 which engages the edge 17 of the template and which is driven through an arm 26 and a sprag-type one-way clutch from the machine rocker shaft. The template is thus moved intermittently, and only when the needle is out of the material. The roller is supported by an arm 20 (Fig. 2) pivoted at 21 and biased anti-clockwise by a spring 24. In operation the machine stitches the cloth until when near the end point 10 a first ramp raises the presser foot 50 and through a linkage 52, lever 53, and switch 56 increases the stitch density control 60. A second higher ramp 15, 16 raises the presser foot higher, and through a linkage 52 and a second switch 62 pneumatically switches off the motor 67, and actuates the conventional needle-position and thread trim systems. A foot controlled pneumatic valve 68 is then pressed to lift the presser foot and knife 71a clear of the template. The cylinder 72 and piston 73 (Fig. 2) also pushes the lever 77 and pawl 78 so that the roller rotates and moves the template to the starting position for the next sewing cycle (at 11). When the foot control 68 is released the piston 73 is withdrawn, the presser foot and knife lowered and the motor started. The presser foot is against a ramp 14 so the stitch density control 60 remains at its higher setting until the presser foot moves off the ramp. The stitching cycle then repeats. The roller 19 has a knurled or V-shaped edge, and means other than ramps may control the sewing machine, e.g. photoelectric apparatus. The guide member 3a may be replaced by a roller on the presser foot. (For Figures see next page)
