Title: Gas discharge indicators
Inventor: WARNE L C
IPC: H01J17/49
Filed: 1970-12-30
Abstract: 1341850 Welding by pressure SPERRY RAND CORP 30 Dec 1970 [23 Jan 1970] 61715/70 Heading B3R [Also in Division H1] A gas discharge indicator for displaying symbols comprises a sealed envelope containing ionizable gas, a plurality of spaced flat cathodes 6, on pins, each cathode forming an elemental part of the desired symbol and the flat surface thereof shielding a portion of the interior surface of the non-conductive back base, and flat planar anode(s) 5, 7 in the common plane of the cathodes and co-operable with the cathodes for shielding the interior back surface, thereby inhibiting sputter deposition and the formation of cathode shorting paths along the base between pins, the anode(s) and cathodes being spaced from the interior surface of the base by 0À005 inches. In Fig. 1, triangular elements 6 are decimal points, viewing faceplate 1 may be glass or other transparent or translucent material, peripheral spacer 2 may be replaced by a peripheral ridge or wall in glass base 4 or the faceplate, Figs. 4, 4a and 7 (not shown) also showing fill tube 9 and hole 10 which may alternatively be in plate 1 or spacer 2. Anode and cathode elements are fabricated from common sheet 3 (e.g. 0À005 inch stainless steel) by stamping, etching, laser cutting, ultrasonic means, electroforming or electrical discharge machining. Fabrication may be as in Specification 1,330,710. In manufacture, tabs (not shown) interconnect all elements, the tabs providing high electrical resistance for later removal. The pins may be replaced by L-shaped support pieces with the longer limb extending to base 4 edge for attachment to drive circuitry, the longer limbs being printed for example. The pins may be formed by etching away an initially flush base 4 surface also forming indentation 8 due to preferential etching, serving to inhibit sputtering effects. Pin-electrode joins may be by electric welding either singly or by a multielectrode welder as described, and the tabs then resistance melted. Reference is included to planar raised cathodes as in Specification 1,272,674 in which anode and cathode elements occupy a common plane. In Fig. 2 (not shown), anode 5 surrounds each cathode 6; Fig. 3 (not shown) shows separate gas tube modules interchangeable within an array of modules forming a display panel; Fig. 5 (not shown) includes peripheral metallic strip (12) incorporating anode elements 5, with the faceplate attached to flange 5 or extending down and embracing strip 12, and rectangular, circular or other base shapes are instanced. Fig. 6 devices (not shown) may be incorporated in indicator 14 (Fig. 7, not shown), with a common gas filling envelope.

Patent GB-2008887-A (GB)
Title: Method and apparatus for determining the rotational position of objects
IPC: A63B21/02
Filed: 1978-10-03
Abstract: Angular position of an object is determined by scanning an image of the object B and comparing the scanned data with stored data of a reference object GR. For a given radius, a set of circular scans is effected for different relative angular positions of the object image and reference object and for each scan the object image and reference object data are cross-correlated and integrated about the scanning circle. The correlation integral with the absolute extreme value gives the actual angular position of the object. The procedure may be repeated for different radii. Stores GSp and RSp for the object and reference object data are connected to multiplier M and integrator I and the data are recalled and the correlation controlled by correlation control circuit KSt, the extreme integral value being selected by stores Sp1 and Sp2 for the computed integrals and an associated comparator D3. <IMAGE>

Title: Apparatus for testing the base folding of bases formed on tube sections
IPC: B31B70/00
Filed: 1979-01-29
Abstract: In the production of bags from tube sections 2 provided with folded bases 1, wherein the sections are conveyed transversely (arrow 3) in a flattened condition but with the bases 1 at right-angles thereto, photocells 4 to 7 on one side of the bases 1 are disposed to scan parts of the edges or fold lines of the bases and are spaced apart so that, if the bases are formed correctly, light from a source on the other side is simultaneously blocked to all of them by the bases.

Title: Pressure Limiter for Hydraulic Brake Booster
IPC: B60T13/12
Filed: 1979-07-30
Abstract: The booster comprises a housing which defines a pressure chamber 26 and supports a control valve 32 and a piston 34. The control valve co- operates with an actuator 36, 38 to move relative to the housing so as to communicate pressurized fluid from inlet 50 to the pressure chamber and the piston is movable in response to the pressurized fluid within the pressure chamber to effect braking. In order to limit the level of pressure of pressurized fluid communicated to the pressure chamber a ring 56 is disposed within the housing in co- operation with the control valve. The ring co-operates with the control valve to define a differential area which is exposed to pressurized fluid to generate a force opposing movement of the control valve so that communication of pressurized fluid to the pressure chamber is limited. <IMAGE>
