Abstract: 441,500. Stereotype matrices. HOWELL, A. H., 211, Queen's Road, Vimbledon, London. July 21, 1934, No. 21381. [Class 100 (ii)] In apparatus for drying stereotype matrices having a drying arch upon which the matrices are to be placed, a flexible cover plate for the arch is provided adapted to be wrapped round the surface of the arch from one longitudinal edge of the arch to the other. As shown, the cover plate 3 consists of a perforated sheet of spring steel anchored at one end to a bar 5 extending parallel with one longitudinal edge of the arch 1, and anchored at the other end to a bar 6 which is yieldingly secured to a supporting bar 7. The bar 7 extends between a pair of end plates 10 each fitted with rollers 11 adapted to run on an involute-shaped track 12, serving to guide the movements of the cover plate 3 into and out of operative position. The tracks 12 form part of a frame 13. The flat matrix to be dried is placed against the cover plate 3, and the latter then turned downwardly over the arch, preferably by means of a handle 14, until the rollers 11 reach the portion of the track of minimum radius at the front edge of the arch. The rollers ride over studs 15 whereby the bar 7 and cover plate are locked in the operative position. The lower bar 5 may be fixed in relation to the edge of the arch, but is shown as being spring-pressed towards the arch by springs 20 mounted on studs 19 passing through the bar into the arch. Rods 21 rotatably mounted on the base 2 of the apparatus pass through slots in the bar 5, and are provided with eccentric lugs which engage lugs on the bar 5, whereby when the rods are rotated the bar 5 is moved away from, or allowed to move towards, the arch 1. The rods 21 have lateral arms 24 at the top ends which are engaged by the end plates 10 of the bar 7 when the latter is moved into the inoperative position thereby causing the bar 5 to move away from the arch 1. When the bar 7 is moved downwardly, the bar 5 moves towards the arch 1 to grip the matrix. Pins may be provided on the bar 5 to assist in locating the matrix. A layer of metallic gauze may be secured to the front of the cover plate 3 to assist the dispersion of vapour from the matrix. The surface of the arch may be provided with a layer 17 of asbestos or the like.

Title: Improvements in and relating to astronomical reflectors
IPC: D06P3/79
Filed: 1966-05-16
Abstract: 1,110,689. Moulding reflectors. Z. HERPAY. 15 Aug., 1966 [16 May, 1966], No. 21578/66. Addition to 1,108,523. Heading B5A. [Also in Division G2] A method of constructing an astronomical reflector as in the parent Specification, comprising the steps of using a silver-steel, glass or other rigid tool to make a base of complementary shape to that desired for the final reflector and having an accuracy at least equal to a wavelength of the light used with the reflector, stretching a reflecting film or skin over the base, forming a backing on the film or skin and removing the finished reflector from the base. In order to make the reflector lighter in weight the backing is formed by a multiplicity of rigid bodies adhesively secured to the reflecting skin. The rigid bodies may be bricks or tubes of carbon fibre reinforced polymers. To enable the reflector to withstand temperatures up to 400 C., polyimide resins may be used. For forming a large reflecting skin as is necessary in making a large reflector, a skin may be formed on a number of optically flat rectangular sections of glass which are subsequently pressed together on a large flat surface with their edges secured together with self-adhesive strips to prevent a keying material from oozing through the slight gaps between the sections.

Title: Improvements in or relating to bale-tying mechanism for baling presses
IPC: A01F15/14
Filed: 1947-08-07
Abstract: 647,904. Twisting wires together, BURFORD, E. E. Aug. 7, 1947, No. 21610. Convention date, Dec. 11, 1945. [Class 83 (iv)] [Also in Group XVII] Bale-tying mechanism for a baling press (see Group XVII) comprises means for laying a wire w around a bale B to present crossed wire end portions e of substantial length at one side of the bale chamber, and a wire twisting device 264 adapted to engage the wires at or near their intersection and twist them together, the ends of the end portions being free during the twisting operation so that relatively long and flexible end parts thereof are left untwisted. The wire twisting device comprises a rotatable shaft 262 having at its end an elongated spiral finger 280 which may be disposed in a plane perpendicular to the axis of the shaft. However, the finger may be inclined relatively to the shaft axis to control the adjustment of the final tension of the wire about the bales. If the finger is inclined the shaft 262 will be correspondingly lengthened or shortened so that the outer end of the finger is maintained substantially at the location of the cross-over point. A narrow slot or groove is provided in the end of the shaft 262 between the root portion of the finger 280 and the shaft, this groove serving to receive and hold the wires by friction during the twisting operation. Shearing-adjuncts. The shaft 262 carries at its other end a bevel gear 268 which meshes with a mutilated bevel gear 270. This gear 270 is so located angularly that the shaft 262 will have made a half-revolution at the time a wire cutter 258 is actuated to sever the wire. This allows sufficient wrappng of the wire ends to prevent any flying of the severed ends and retains them in the twister. The wire cutter 258 extends into a notch 172 in the end of an arcuate needle 171 which is used to lay the'wire around the fourth side of the bale. As shown in Fig. 7 the ends of the wire wrap themselves about the shaft 262 but slip off readily as the bale is moved along the bale chamber.

Title: Means and method of supporting helical conductors
IPC: C08G81/02
Filed: 1953-08-07
Abstract: 740,852. High-frequency discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Aug. 7, 1953 [Aug. 19, 1952], No. 21854/53. Class 39 (1). [Also in Group XXII] A helix assembly, especially for a travelling- wave tube, comprises a helix secured to longitudinal insulating support-rods by means of an intermediate glaze. In manufacture, the ceramic rods 2, 2a, 2b are cleaned by boiling in acid, then in distilled water, and, if desired, hydrogen fired. They are then sprayed with glaze 3, e.g. frit, and fired in air or other suitable atmosphere to make the glaze flow to a uniform thickness over the area to contact the helix 1. A tungsten helix is wound on a molybdenum mandrel and annealed at 1000 C. to set the helix. The helix and rod assemblies are then cut to the desired length and assembled together with the mandrel still present, using a jig. The assembly is wrapped with twisted tungsten wires at spaced intervals and then removed from the jig and fired for two minutes at 1000 C. in a gaseous atmosphere to bond the rods to the helix. If the helix exceeds a certain length the mandrel must be etched slightly before firing in order to avoid twisting or bending due to slight differences in thermal expansion of the components of the assembly. The assembly is freely suspended vertically during firing in a metal cylinder of high thermal conductivity so as to avoid sagging or twisting. The cylinder is surrounded by a ceramic casing provided with means for introducing the gaseous atmosphere, preferably nitrogen. The initial firing and annealing procedures may also be carried out with the components in a vertical position. After the bonding process the mandrel is removed by selective etching and the wrapping wires are cut away. A molybdenum mandrel, for example, can be dissolved in a solution of H 2 O, H 2 SO 4  and HNO 3 . The tungsten helix may be cleaned in a hydroxide solution. Additional elements such as magnetic shields or impedance matching devices can be glazed to the assembly during the bonding operation. There may be a number of supporting-rods other than three and the helix may be of different material, e.g. molybdenum. The input and output devices may be waveguides or coaxial lines. It is necessary that none of the glaze lies on the inner circumference of the helix. It is stated that the invention is applicable to helices used in other apparatus. The jig in which the elements are mounted is described in detail with reference to Figs. 4-6 (not shown).
