Abstract: 396,106. Drying materials in long lengths. SPOONER, W. W., Ashbrook, Ilkley, Yorkshire. Dec. 29, 1931, No. 3295/33. Divided on 388,167. Drawings to Specification. [Class 34 (i).] Material such as cloth or warp is traversed along a given path and a gaseous fluid such as air is caused to flow in a succession of paths part of which coincides with the path of the web, the fluid being projected on to the web at an angle thereto, and at a relatively high velocity. The speed of the fluid as it leaves the fan or passes through nozzles may be 80 feet per second, so that on reaching the material it will have a speed of say 28 feet per second. The speed of the fluid may be boosted up or increased at spaced localities on the path of the material. For drying, air may be projected first on to the driest part of the web and then on to a wetter part, and for conditioning after drying, leak-off air from the drying cycle may be cooled and introduced into the conditioning cycle. During its flow in or between successive cycles the fluid may be subjected to different treatments, e.g. heating and then cooling. It is preferred to project the fluid simultaneously on to both sides of the web. The process may be carried out as described in Specification 388,167 with reference to Fig. 7 thereof, and the forms shown in Figs. 1 to 6 of the said Specification may be utilized as units of a succession of closed paths, being modified where necessary to give connection between the successive paths.

Filed: 1959-02-03
Abstract: 841,550. Moulding hollow articles. OWENSILLINOIS GLASS CO. Feb. 3, 1959, No.3733/59. Class 87(2). In the making of hollow articles by combined injection, extrusion and blow moulding, the output from an extruder screw 12 is recirculated through an external passage 40, 41, 42 while a part of the article is being injection moulded. The recirculation passage is normally closed by a fluid pressure operated piston 45, but when a conduit 16 is closed by a sleeve valve 32, the piston 45 is depressed and material is returned to a portion 14 of the plasticizing cylinder 11. Sleeve valve 32 is operated by a fluid pressure cylinder 30 which also operates an injection piston 33 having a lost motion connection with the sleeve valve. As shown, the neck of a container is first formed in an injection mould 26, then the body 50 of the container is extruded, Fig. 2, and finally the body is sealed at its lower end and blown to shape in a mould 51 by air supplied at 53. Extrusion is permitted by upward retraction of sleeve valve 32 and plunger 33, and assisted by the piston 45. The neck mould 26 is preferably moved upwardly at a greater speed and to a greater extent than the speed and extent of extrusion, so as to stretch the body 50. Specification 809,534 is referred to.

Abstract: 1424351 Intruder alarms EMI Ltd 17 Jan 1973 [27 Jan 1972] 3797/72 Addition to 1289513 Headings G4N and G4H An intruder alarm comprises a plurality of fence sections S 1 , S 2  ... S n  connected in series around a protected area, each section acting as a waveguide for electromagnetic energy injected by a transmitter T x  and received by a receiver R x , repeaters R 12 , R 23 ..., between each pair of sections including an arrangement for sensing an intrusion in the leading section and for impressing upon the energy transmitted into the trailing section a code indicative of the leading section in the event of intrusion and a further arrangement including a detector DU and a console CC of lamps selectively lit in response to the code to indicate in which section an intrusion occurs. In each repeater shown in Fig. 2 the signal received by R x  is applied via a pulse shaper PS for setting a bi-stable BS which in turn triggers a monostable MS for producing a pulse of predetermined duration which enables an AND gate A and keeps BS latched on via an inverter I and an OR gate X. When an echo pulse resulting from intrusion is received, it is sensed by gate A for modulating the regenerated signal transmitted by T x . A code detector DPC detects and enhances codes already present in the incoming signal.

Title: Improvements in directional lighting fittings
IPC: F21V5/00
Filed: 1933-02-08
Abstract: 414,726. Street &c. lamps. GENERAL ELECTRIC CO., Ltd., and DAMANT, E. L. B., Magnet House, Kingsway, London. Feb. 8, 1933, No. 3868. [Classes 75 (ii) and 75 (iv).] In a fitting adapted to redistribute light from a source into a plurality of preferred directions, means are provided for reducing the effective brightness of some part of the source as viewed from one of the said preferred directions relatively to the effective brightness of some part of the source as viewed from another of the said preferred directions. The invention is particularly applicable to street lamps in which the preferred directions are up and down the street. The effective brightness may be reduced by increasing the effective area of the source, as by means of fluted or ribbed glass, ground glass or like diffusing surfaces, or a series of spaced reflecting strips returning light to the source, or it may be reduced by interposing a medium that absorbs light without altering its direction. The difference in effective brightness may be obtained by using a fluted glass or the like on one side only of the source, or by using two or more glasses having flutes of different light-spreading strengths. In the form shown, a vertical linear electric discharge tube 1 is arranged between a pair of prismatic refractors 2, 2<1> having vertical prisms to direct the light up and down the street and slightly towards the opposite side, these refractors being associated with glasses 3, 3<1> having vertical convex ribs. The glass 3 is adapted to face on-coming traffic on the same side of the street and the effective brightness on this side is made less than that on the opposite side by providing the glass 3 with ribs of less radius of curvature than those on glass 3<1>. Reference has been directed by the Comptroller to Specification 408,419.

Title: Anodizing Metallized Substrates
Inventor: GERHARD ALLEN ROBERT
IPC: C25D17/00
Filed: 1967-01-26
Abstract: 1,169,792. Anodizing. WESTERN ELECTRIC CO. Inc. Jan.26, 1967 [Feb.9, 1966], No.3934/67. Heading C7B. A method of anodizing selected metallic areas on a substrate comprises maintaining each such area in alignment with an opening in a reservoir, allowing the liquid to flow by gravity into contact with each metallic area and applying a current through the liquid in each reservoir to anodize the respective metallic area. As shown substrate 12 has a thin film circuit thereon comprising resistors 13-19 of an anodizable metal such as tantalum, low-ohmic paths 21, 22 and contact areas 26- 36. The substrate is inverted over the surface of block 51 having reservoirs 63-69 corresponding to the resistors and the resistors and reservoirs are aligned by means of locator pins 70 and spring clips 71. Lid 73, when closed and held by spring retainer 78, presses the substrate into contact with the surface of the block by rubber pad 76. Inversion of the block about trunnions 46 allows liquid in the reservoirs to flow into contact with the selected areas on the substrate and in this position current passes between a cathode situated within each reservoir, through the solution and the selected areas, and anodes 101-111 mounted in bores in the block and spring-biased against the contact areas on the substrate. Anodes and cathodes are connected to an external current source and provision is made for monitoring the change in resistance of each selected area as anodizing proceeds.
