Title: Improvements in or relating to thermoplastic film manufacture
Inventor: EULING TERENCE MARTIN
IPC: B29C48/10
Filed: 1961-01-27
Abstract: <PICT:0926393/IV(a)/1> Tubular films of organic thermoplastic material is heated on its interior and exterior surfaces by radiant heaters, mounted centrally inside and around the outside of the tube, and expanded by inflation with a gas, e.g. air, so that the tube is stretched and oriented.  The process is particularly applicable to films of linear polyesters, e.g. polyethylene terephthalate, and to highly crystalline polyolefines, i.e. those with crystallinity above 50% measured by X-ray diffraction, e.g. polyethylene and polypropylene.  The heaters may be e.g. infra-red or wire-wound radiators or induction heaters comprising a cylinder of iron used in conjunction with an electromagnetic coil.  The internal and external heaters may be placed in substantial alignment, and the former may be used in combination with a locating means placed inside the tube, e.g. a brass cylinder contacting the interior of the film, or a cylinder of sintered metal through which air is supplied to form an air bearing between film and cylinder.  In a preferred embodiment, a polypropylene film 1 is melt-extruded through annular die 2, quenched (by means not shown, see Specification 741,963), passed through nip rollers 3, heated to the stretching temperature by wire-wound infra-red heaters 4 and 5 and then inflated.  A further external heater may be located adjacent the stretching zone.  The internal heater 4, which may be made rotatable, is maintained in position by brass-cylinder 6, sand-blasted and chromium plated, and mounted upon pipe 7 to which heater 4 is also attached.  Air is supplied under pressure through orifice 8 in pipe 7 to inflate the tubular film. Sealed and nitrogen-filled quartz jacket 9 surrounding heater 4 reduces uneven heating of the film by convection, the effects of which may also be minimized by continuously circulating and removing, via pipe 7, the air between locater 6 and internal heater 4. Specification 787,479 also is referred to.

Abstract: 324,813. Raleigh Cycle Co., Ltd., and Wilkie, W. Feb. 2, 1929. Controlling variable-speed gearing. -In order to impart definite stepped angular displacements to a disc b which controls a variable-speed gear through a link k, Fig. 5, repeated oscillations are given to a pedal or handlever d. The parts are supported centrally on a fixed pivot c which passes through a fixed plate a between which and disc b are toothed means, not shown, for locking the latter in gear positions. The lever d is adjustably secured to a pivoted arm e which carries a double-acting pawl g. Supported on the plate a is a spring plunger h, Fig. 6, which normally holds the pawl g in a middle inactive position shown in Fig. 5. The disc b has two sets of ratchet teeth b<2>, b<3>, each tooth corresponding to one step of the disc b in that direction. When the lever d is moved, the pawl g is tilted by plunger h into engagement with a ratchet tooth. Continued movement turns the disc b through the space of one tooth until a stop i is struck. The arm e and lever dare returned to mid-position by a V-shaped spring dog j, Fig. 6, whereupon the stroke may be repeated in the same direction, or reversed by moving the lever d upwards. Instead of stops i, a pin j<2> may terminate a stroke by stopping the axial movement of dog j. A modification is described in which the pawl g works in a window in the disc b, the window being formed with the two sets of internal ratchet teeth.

Title: Improvements relating to methods of and apparatus for the cooling of hot gases by direct contact with water
Inventor: BRITTAIN CHARLES PETER
IPC: F28C1/02

Abstract: 1,082,511. Cooling gases by direct contact with water. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 20, 1964 [Jan. 29, 1963], No. 3655/63. Heading F4K. In a plant for preparing cooled process gases said gases are passed directly in contact with a body of cooling water of low available oxygen content which is passed in a closed cycle through a heat-exchanger, arranged externally of the path of the gases, in which the cooling medium is kept physically separate from the said body of water to avoid oxygen pick-up by the cooling water. Gases pass from a combustion chamber 1, down a duct 2 and up through a stack of porcelain rings 3 (or Raschig rings), contained in an outer casing 4 concentrically surrounding duct 2, before being discharged through outlet 4a. The body of cooling water is circulated by a pump 15 from a lower reservoir 5 through a heat exchanger 16, arranged externally of the path of the gases, to two upper reservoirs 10, 11 of which the upper, 10, supplies duct 2 with cooling water flowing co-currently with the process gasps while the lower, 11, supplies stack 3, from sprinklers 13, with cooling water flowing counter-currently to the process gases. An overflow 6 and water lock 7 may be provided and/or extra cooling water may be added, either through pipes 23, 24 or by saturation of the process gases, depending on the water vapour content of the process gases before cooling. Heat exchanger 16 may be used for a hot water supply system or may be used to heat any sort of fluid as required. In some applications, in which the oxygen content of the process gases may not be critical, the cooling water may enter through 23, 24 and leave through overflow 6 without recirculation; in these cases, heat exchanger 16 may, or may not, be included in the water outlet system. In a modification (not shown) two separate cooling water circuits are employed: one, having a high rate of flow of water, being a closed cycle as above and the other, having a low rate of flow of water, being a straight-through circuit. Heatexchangers such as 16 may be included in either or both of these circuits.

Filed: 1964-01-29
Abstract: 1,025,453. Semi-conductor devices &c. STANDARD TELEPHONES & CABLES Ltd. Jan. 29, 1964, No. 3783/64. Heading H1K. To mount a semi-conductor wafer a layer of an alloy containing gold and the semi-conductor is formed on one of the faces of the wafer and a mixture containing gold and a conductivity type determining impurity is added to the surface of this layer. The wafer is then placed with its prepared face in contact with a mount and heated in a neutral or reducing atmosphere so that on subsequent cooling the wafer becomes firmly attached to the mount. In an embodiment planar transistor structures are formed in an N-type silicon slice by diffusion into one face. The other face is lapped and the slice washed and dried. The slice is heated to 400‹ C. and gold containing a small amount of antimony evaporated on to form a layer of molten alloy with the silicon. This layer is solidified by cooling the slice to below 200‹ C. and a further amount of gold/antimony alloy deposited at this reduced temperature. Next the slice is separated into individual wafers each of which is placed with its alloy layer in contact with a gold-plated header. The assemblies are passed through a furnace at 450‹ C. (in a nitrogen or nitrogen/hydrogen atmosphere) when the gold/antimony acts as a brazing metal to join the wafers to the headers. Each device is provided with leads and encapsulated. In variants the temperature of the slice may be progressively reduced during the alloying operation and the alloy deposited in other than two stages. Arsenic may replace antimony in the doping impurity and boron may instead be used if the original slice is of P-type conductivity. Instead of doped gold a doped gold/ silicon alloy may be deposited during the process. The header may be nickel-plated or may be unplated iron/cobalt/nickel alloy. Germanium or intermetallic compounds may replace the silicon as semi-conductor. Devices other than transistors may be similarly mounted.

A control system for regulating the pressure inside a chamber, such as an aircraft cabin, comprises a capsule 13 which is subjected externally to cabin pressure and connected internally to a chamber 43 via a variable orifice 44, movement of the capsule walls being communicated to a lever 15 which operates flap valves 16, 17. Movements of the lever resulting from changes in aircraft height are delayed by the clamping action of orifice 44 and chamber 43, and such movements produce unbalance in the control pressures applied at 28, 29 to a pure fluid amplifier 22 Fig. 1 which alters the control pressures applied at 24 to amplifier 25, connected to bridge 31 fed with pre-set pressure signals via lines 33, 34 and variable controls 32, 0À1. The latter constitutes an altitude selector. The resulting unbalancing of the bridge produces pressure changes in line 36 which, through pure fluid amplifiers 38, 41, operate a relay 5 controlling cabin vents 6, 7 to regulate cabin pressure as the aircraft's height varies but at a rate selected by the effective size of orifice 44.
