Title: Improvements relating to Cathode Ray Tubes and Focusing and Deflecting Arrangements Therefor.
Inventor: MAYO BERNARD JOSEPH
IPC: H01J29/46
Filed: 1965-09-25
Abstract: 1,165,002. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. 15 Sept., 1966 [25 Sept., 1965], No. 40904/65. Heading H1D. The electron-optical system of a cathode-ray tube includes a first cylindrical lens formed at the entrance end of a first pair of deflection plates by co-operation with a preceding pair of plate electrodes, for focusing the electrons in a line focus perpendicular to the plane of deflection, and a fine mesh grid positioned between the first and a second pair of deflection plates, to form with the second pair a second cylindrical lens for focusing the electrons in a line focus perpendicular to the second plane of deflection, whereby, by choice of the potential applied to the mesh grid, the curvature of the image field may be controlled to render the focus of the beam more uniform over the target area of the tube. In a videcon tube having a target 1, the plates 3 are held at a low potential relative to the mean potential of the deflection plates 4, to form a convergent cylindrical focusing lens therewith, while the fine mesh electrode 5, which may be held at the mean potential of plates 4, provides a lens action which varies with the deflection voltage and may be used to counteract curvature of the image plane introduced by the succeeding deflection plates 6. Electrode 5 forms with plate 6 a second converging cylindrical focusing lens, the variable component of which has little effect on image curvature due to its position at the pre-deflection end of plates 6. A second mesh grid may be positioned on the target side of the plate 6, and both the mesh grid or grids and the deflection plates may be curved. In modified arrangements the plates 6 may be of stepped form (Fig. 4, not shown), and plates 3 may overlap plates 4 (Figs. 5(a) and 5(b), not shown).

Abstract: 1,037,107. Ventilating cushions. ALPHA RESEARCH CORPORATION. Oct. 16, 1963, No. 40939/63. Heading A4M. [Also in Divisions B5 and D1] A ventilating cushion comprises intersecting wire coils 22 wound around a border wire, and an outer cover formed by two sheets 20, 21 at least one of which is of open mesh fabric, the free edges of the sheets 20, 21 being secured together by a line of stitching 24 which extends also through the free edges of binding tape 23 wrapped around the said sheet edges and being further secured to each other and to the binding tape by a viscous, spreadable adhesive 25 machine-applied to the sheets 20, 21 prior to stitching and to folding of the tape 23, intermittently in an area which is intermediate the free edges of the sheets and the subsequently applied line of stitching 24. The cushion may comprise a seat back portion 17 and a seat portion 18 hinged together along a transverse line of stitching 19. In an apparatus for securing the sheet edges, which apparatus includes a suitable sewing machine, the sheets 20, 21 with the coils 22 located therebetween are advanced continuously by a work feed mechanism 14, and in sequence sheet edges are trimmed by a reciprocating knife 11, adhesive is applied in a line 63 from a dispenser 34, binding tape 23 is applied by a folder 30 co-operating with a presser foot 28, the adhesive 25 is initially spread under pressure between the foot 28 and the feed mechanism 14, stitching 24 is made by a needle 13, and the adhesive 25 is further spread under pressure. The moving parts of the apparatus are driven by the sewing machine in timed relationship with the feed mechanism 14, causing a pivoted arm 41 carrying the trimming knife 11 to reciprocate vertically and at the same time reciprocating a bracket 45 carrying a spring urged pawl 46 co-operating with a ratchet wheel 40, the latter carrying a cam 50 which intermittently engages a pin 51 engaged in a helical slot 52 in the wall of the adhesive dispenser 34 whereby downward movement of the pin 51 causes a rod 56 mounted within a plunger 55 carrying the pin 51 to close the outlet 57 by engaging a ball 58 and thereby intermittently interrupt the supply of adhesive to the fabric sheets 20, 21.

Abstract: 1444665 Compacting moulding material W HABERLE 20 Sept 1974 [29 Sept 1973 22 March 1974] 41044/74 Heading B5A Apparatus for compacting moulding material 2 comprises a non-rotatable member 22 which has a conical pressing surface 23 and which is connected via roller bearings 26 to a stub shaft 24a inclined at an angle α to the vertical so that as the stub shaft 24a is driven by a crank 28 the line of contact of the member 22 with the moulding material 2 rotates but the member 22 merely rises and falls with non-rotation. To prevent rotation of the member 22 and associated mould 11, a finger 38 is provided on the member 22 to lie between vertical guides 36, 37. The angle α may be chosen so that the surface 23 produces a flat or curved surface on the material 2. For pressing material having a large area, a plurality of members may be provided (62, Fig. 3). Adjacent members (62) may be driven in opposition to one another by providing intermeshing gears (74, Figs. 3, 4) driven by a common motor (71). The members (62) may also be driven by respective hydraulic motors (81, Fig. 5) mounted on the drive shafts (68). Pneumatic cylinders, e.g. 31, 12 (75, Fig. 3) may be associated with the member(s) and/or material for urging the member(s) and material into contact. The compressed material may be removed by lowering the mould relative to an ejector 18. The member 22 may have a circular, square, rectangular or polygonal periphery. The material 2 may be concrete, lime, sand, gypsum, mortar, and ores. Stones and slabs, split stone blanks, channel slabs, curbstones and edging stones may be formed.

In a method of forming pre-stressed concrete and like bodies according to which reinforcing wires are made to traverse a plurality of moulds arranged in rows on a mould bed, the wires 21, Fig. 1, are fed from reels (not shown) through a distributer head 20 and through holes in a pair of clamped anchor plates 12, 13 and the ends are held by wire grips. The plates are moved forward until plate 12 is arrested by beams 11 which are abutted by hydraulic rams 10 carried by a buttress 2. The plate 13 is then unclamped and is moved forwards and upwards by a trolley 15 mounted on rails 16 and pulled by a cable 33 by means of a winch 17 at the distant end of the bed, Fig. 1a. The wires 21 are carried by rollers 35, Fig. 6, and spaced apart by guide fingers 28 above moulds 25 positioned at intervals along the bed, the moulds being supported by arms 23 and columns 22. The arms 27 carrying the guide fingers 28 are lowered and the wires 21 guided into vertical slots in the mould end plates (not shown). Meanwhile the winch 17 maintains the tension in cable 33 and hence in the wires, and the end of the cable is aligned with the wires 21 by the vertical adjustment of rollers 29 on a carriage 30. The plate 13 is then fixed to the buttress 4 and the wires 21 severed just beyond the distributer head 20, the severed ends being pulled backwards at the feed end of the bed to tension the wires, and concrete or like substance is introduced into the mould.

Filed: 1964-10-12
Abstract: 1,060,168. Voltage measurement. VAKUTRONIK VEB. Oct. 12, 1964, No. 41564/64. Headings G1Q and G1U. The input circuitry of an electrometer is contained in a screening box in the form of a cylindrical or parallelepipedic casing. As depicted in Fig. 1 (not shown) the electrometer consists of a variable capacitor and associated amplifier and includes a resistor (11) and capacitor (12) as part of the amplifier input circuit. In a feedback loop from the amplifier output resistors and/or capacitors (1, 2, 3) are selectively switchable to determine the measurement range. All these components (1, 2, 3, 11, 12) are mounted inside the casing and the switches are contacts of a relay also mounted on or in the casing. Figs. 2 and 3 (not shown) depict a suitable arrangement of the components in a cylindrical ferrous casing. In Figs.4 and 5 (not shown) the casing is of glass, sealed under vacuum, and screening is achieved by coating the outside of the container with graphite or silver and attaching a ferromagnetic ring (19) to that part of the casing which immediately surrounds the relays.

Alternatively the laser device may move bodily during cutting. Supports 1 are provided for the metal 2 and shielding means 12 move into the path of the beam when no material is present. A heat sink 13 comprises a tank of liquid 13 which may be particles suspended in water; alternatively flowing liquid may be used. The liquid is opaque to the light produced by the laser. A number of laser units mounted side by side may be used to make straight or profiled cuts. The laser device may be mounted below the metal to be cut.
