Title: Improvements in or relating to heat exchange tubes
Inventor: WALL ALAN JAMES
IPC: F28F1/36
Filed: 1969-02-24
Abstract: 1,272,621. Make finned heat exchange tube; angular bending; welding by pressure. CLAYTON DEWANDRE CO. Ltd. 30 Jan., 1970 [24 Feb., 1969], No. 9695/69. Headings B3A, B3E and B3R. A method of forming a helically wound fin, in the form of wire loops, on to a heat exchange tube comprises bending wire to a zig-zag formation in a single plane to form a strip of fin material, bending the strip so formed to a substantially U-shaped cross-section but with one limb 3b inclined outwardly, winding the bent strip helically on to a rotated and axially fed tube 6 with the base 4 of the bent strip contacting the tube, bonding the base to the tube using a revolving resistance welding electrode which bears down on a bonding wire 5 placed in the base 4, and bending up the inclined limb 3b of the strip material after the welding step so that both limbs extend perpendicularly to the tube wall. The upward bending of the inclined limb 3b is effected either by a forming roller 8 or a fixed cam 9.

Patent GB-653757-A (GB)
Title: Melt-spinning process and apparatus therefor
IPC: D01D1/09
Filed: 1948-04-09
Abstract: <PICT:0653757/IV (a)/1> Synthetic linear polyamides are melt-spun by introducing the polyamide and water vapour into a heated space to melt the polyamide and to provide a constant vapour pressure of water, and extruding the polymer.  As shown, the polymer in flake form is fed into the melt spinner by means of an open hopper 11 into a preheater 12, heated by a steam jacket 13 or other means.  Steam at 10-100 lbs./sq. inch pressure and 115-170 DEG  C. is supplied to the jacket at 14 and withdrawn at the bottom of the jacket.  At 16 a portion of the steam is bye-passed through a pipe 17 carrying a valve 18 and thence to a chamber 19, where it is at atmospheric pressure. Steam from the chamber 19 passes up through the polymer flake and out into the air at 20, thus blanketing the polymer. After mixing with the steam, the flake passes to a grid melter heated by steam, electricity or other means.  The molten polymer is pumped from the pool 22 by the pump 23 and delivered to the spinneret assembly 24. By this means a constant amount of moisture is maintained in the melt resulting in a more uniform yarn.  The steam pressure in the chamber may be as high as 30 pounds per square inch, but steam pressures of 7-10 pounds per square inch are satisfactory, the maximum pressure depending on the polyamide to be spun and the type of yarn formed. Polymer flake with a moisture content as high as 6.5 per cent may be used, although flake which has reached equilibrium with atmospheric conditions and contains about 4 per cent moisture is preferred. It is not necessary to dry or condition the polymer before spinning. Suitable polyamides are polyhexamethylene adipamide, polytetramethylene adipamide, polytetramethylene sebacamide, polypentamethylene adipamide, polypentamethylene sebacamide, polyhexamethylene sebacamide, polyhexamethylene glutaramide, polyoctamethylene adipamide, poly-p-xylylene sebacamide, the polyamide from 3,31-diaminodipropyl ether and adipic acid, and polymerized epsilon - aminocaproic acid, 9 - aminononanoic acid and 11-amino-undecanoic acid, and these may be used singly or mixed. Specifications 461,236 and 461,237 are referred to.

Title: Method of manufacturing an electrical surge arrester/diverter
Inventor: DOONE RODNEY MEREDITH
IPC: H01C7/12
Filed: 1995-12-14
Abstract: A distribution class surge arrester comprises a core formed of distributed zinc oxide varistor blocks, aluminium blocks acting as heat sinks and as spacers providing voltage grading and required arcing distances, and terminal blocks held in face to face contact by means of a glass reinforced epoxy shell which is formed by winding a pre-preg onto the assembled blocks and thermally curing under mould pressure within an evacuated mould. The core is housed within a polymeric shedded housing which is formed by shrinking a heat-shrink shedded sleeve onto the core with a sealant provided in the interface of the core and the sleeve, and end caps are sealed to the ends of the structure thus formed. The all solid-state arrester thus formed has performance and cost advantages over conventional porcelain housed arresters and furthermore has very considerable physical strength enabling it to serve additionally as a stand-off support insulator in situations where con­ventionally separate arrester and support insulators were required.

Title: System and method for coding speech
Inventor: MOULSLEY TIMOTHY JAMES
IPC: G10L19/12
Filed: 1990-08-13
Abstract: A speech coding system of the code excited linear prediction (CELP) type comprises means (24,26) for filtering digitised speech samples to form perceptually weighted speech samples. Entries in a one-dimensional codebook (110) comprising frame length sequences are filtered in a perceptually weighted synthesis filter (28) to form a one-dimensional filtered codebook (38). The filtered codebook entries are compared with the perceptually weighted speech signals to obtain a codebook index which gives the minimum perceptually weighted error when the speech is resynthesised. Using a one-dimensional codebook (110) reduces the amount of computation which is required compared to using a two-dimensional codebook.

Abstract: The invention relates to a process and an apparatus for electrolytically depositing, in a moving mode, a continuous film of nickel on metal wire for electrical use. The process comprises using an activation bath and a nickel-plating bath in which the current density is reduced in the upstream portion of the nickel plating bath and/or the downstream portion of the activation bath and the acidity of the nickel-plating bath is so regulated as to develop the nickel in the form of strongly adhering globules of small diameter, which completely cover the wire. The reduction in the above mentioned current density and control in respect of the current density profile along the bath may be achieved by acting on the position of the electrodes in the bath and/or by interposing screens between the electrodes and the wire.

Title: Metallic finish of plastic molding

Filed: 1982-01-07
Abstract: PURPOSE:To obtain a metallic finished plastic product having good adhesion and excellent appearance and quality easily at low cost, by a method wherein the surface of a plastic molding is subjected to plasma treatment and then to metallic finishing. CONSTITUTION:The surface of a plastic molding 6 (e.g., PP, Teflon) is subjected to plasma treatment to form a modified layer so as to improve adhesion. On the surface of the layer 7 are formed, in turn, base coat 8 (e.g., polyester-modified urethane coating), metallic deposit 9 (e.g., Ag or Cr plating by sputtering), top coat 10 and, if necessary, overlay 11. So far, the surface of PP, Teflon, etc. has been difficult to undergo metallic finishing because of low surface energy, poor hydrophilic and lyophilic nature, and deficient adherence to base coat as a result of being free of polar groups. Howerver metallic finishing becomes possible by means of plasma treatment of the surface thereof.
