Abstract: 768,328. Pile fabrics. MOHASCO INDUSTRIES, Inc. April 25, 1955 [July 22, 1954], No. 11882/55. Drawings to Specification. Class 142 (4). [Also in Group XVI] Pile fabrics, in which the pile yarns are wholly or partly of heat-skrinkable material, are embossed to form depressed areas, the yarns in the depressed areas being simultaneously heated causing the yarns to shrink. The fabric is produced on a backing, e.g., of cotton by a tapestry loom or by a tufting operation on a sealing machine. The pile yarns may be formed by plying together yarns spun from heat-shrinkable and non-heat shrinkable fibres respectively, or preferably from blends of fibres e.g., viscose rayon and polyvinyl chloride; wool, viscose rayon and polyvinyl chloride, or polyvinylidene chloride and polyvinyl chloride.

Abstract: 411,651. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Kenty, C. E. ; 650, Palisade Avenue, Jersey City, New Jersey, U.S.A.) April 24, 1933, No. 11922. Convention date, April 25, 1932. [Class 39 (i).] A device, more particularly a lamp, comprises a resistance wire extending from a point near the cathode to a point near another electrode and connected to that electrode through a resistance, and the resistance of the wire per unit length of discharge path increases progressively towards the cathode. Preferably the surface area of the resistance wire decreases towards the cathode. In one form, Fig. 1, a resistance wire 11 consisting of a tapered wire or a helix of tungsten or the material known under the Registered Trade Mark "Nichrome," of decreasing radius and pitch approaching the cathode, is mounted with one end adjacent the anode 10 and the other, provided with a small collector 12, adjacent the cathode 4. The wire 11 is connected to the anode through a resistance 16 and the anode is connected to the cap 14 through a ballast resistance 15. The cap 15 is connected to the sleeve of the cap 13 by a strip 17 of aluminium foil. The cathode heater is connected to the contacts on the cap 13. The cap 14 may be perforated to allow of cooling. In a modification, Fig. 2, for use on alternating-current, the wire 11 is connected through a resistance 16 and the opposed rectifiers 34 to the anodes 28, or one of the rectifiers may be omitted. In another modification a tube has two heated electrodes, for alternating-current supply, and two resistance wires are connected to them through rectifiers and are parallel to each other and function on alternate half-waves. To assist excitation, the filling may consist of a rare gas with a small percentage of another gas having its ionizing potential of the same order as a metastable potential of the main gas, e.g. neon together with 0À2 per cent argon. Or the filling may comprise only neon at a pressure of 0.5 to 3À5 mms.

[Also in Division B8] An apparatus for separating a flowing medium, such as a liquid, into individual sections 22 by forcing into the liquid, at predetermined intervals, a second medium such as a gas, comprises a body 5 having a duct 6 for the liquid, and at least one further duct 8 leading into the duct 6 for introducing therein the second medium via a dosing device 19. As applied to chromatography the liquid is fed by a pump 1 through a column 3 into the duct 6 which connects with a duct 9, the latter communicating with an outlet 15 via a flexible pipe 10, a capillary reactor 11 and a photometric measuring cell 13. The dosing device 19, which may be a pump, draws a gas, such as argon, from a pressurized container 18 and forces it at pre-determined intervals into the stream of liquid thereby separating the latter into separate sections. In modifications, a further medium may be introduced into the liquid either into the continuous stream in the duct 6 or into the separated sections 22 in the duct 9. In order to assist the introduction of the gas into the liquid at the junction point 7 of the two ducts 6, 9 the flow of liquid through the duct 6 may be slowed down or stopped momentarily by means of a pulsator 24.

Title: Surface treatment of polyethylene terephthalate structures such as films
Inventor: GATES WILLIAM ELLIOTT FREW
IPC: B29C59/08
Filed: 1955-04-29
Abstract: The surface bonding properties for printing inks and other materials of a drawn and heat-set polyethylene terephthalate film or other article are improved by applying a flame to the surface for a time that is insufficient to cause distortion of the film &c.  In the example, a film of polyethylene terephthalate 0.0005 inch thick is produced by melt extrusion into water followed by drawing the quenched film at 80 DEG  C., both longitudinally and laterally, and heat-setting the drawn film by raising its temperature to 180 DEG  C. without allowing it to shrink.  The tip of a Bunsen burner flame 2-3 inches long is played over this film while it is supported on a cold backing roller so that the flame at any instant covers 0.5 square inch of film and is moved over the film at such a rate that 24 square inches of surface are treated per second.  Specifications 603,840 and 704,665 are referred to.

Abstract: 1497120 Measuring liquid level electrically B J HIGGINS 26 March 1975 [29 March 1974] 12613/75 Heading G1N An elongated multi-electrode liquid level probe for use in a tank or well comprises a plurality of metal collar sections 2A, 2B separated by insulating sections 1A, 1B which screw into the collars 2A, 2B. A plug 7 threaded to the lower end of section 2B seals the interior of the probe. Leads connected to the terminals 4 attached by lugs 3 to the collars extend upwards through the probe to the exterior and after the probe has been filled with insulating material such as sand the top is sealed by epoxy resin. The probe is mounted vertically in e.g. a sewage tank and as the level rises to bridge the collars signals are produced due to the lowering of the resistance between the collars and the lowest collar 2B. Thus when the level falls to 2B a pump is stopped and the level is allowed to rise to the collar at a second level which when reached causes a signal to be passed to the pump to start it and pump the level back to 2B. If the pump fails and the level rises to the collar at a third level a standby pump is activated and the level cycles between this level and level 2B. If on failure of this pump the level reaches a further collar at a fourth level an alarm is activated. In order to protect the probe from solids in the liquid a pipe may be  positioned around the probe which may be provided with a filter across the bottom and/or small holes in the pipe.

Abstract: 1347461 Coating with glass NORTHROP CORP 3 May 1971 [1 May 1970] 12631/71 Heading C1M [Also in Division H1] A method of making a dynode plate wherein a substrate plate of insulating material is first formed with a plurality of holes therethrough and wherein the insides of the holes are then glazed with a glass and treated to convert at least the surface of the glaze to a semi-conductive and secondary emissive state. Reference is made to electron beam scanning multiplier devices and electron multipliers. In Fig. 1 (not shown), holes (13) may be up to 20 degrees inclination and 50 to 500/inch in a photosensitive crystalline ceramic (e.g. " Fotoceram ", Registered Trade Mark). Glazing may be with lead glass or bismuth, iron oxide, vanadium, uranium, strontium and titanium glasses, or chalcogenide glass with a thermal expansion preferably matching that of the substrate. The lead glass composition may, for example, be 30 to 60 mole per cent of the composition and may include PbO, SiO 2  and B 2 O 3  with Bi 2 O 3  to establish the desired surface resistance. The SiO 2 , B 2 O 3  content controls the m.p. to a temperature below the deformation point, B 2 O 3  also controlling the wetting. Typical composition may be, in mole per cent; PbO-45; B 2 O 3 -30; SiO 2 -9; CuO-3; ZnO-6À30; Bi 2 O 3 -6; Al 2 O 3 -0À30; Zr 2 O 3 -0À20; TiO 2 -0À10 with traces of Fe, Mn, Ca, Ag &c. amounting to <0À10%. Water frit is produced by pouring hot melt on to water, ball milled to <5 Á, further liquid producing a 1À0 to 1À30 s.q. Cleaning techniques for the substrate are described, the substrate being then dipped into a particle suspension, preferably ultrasonically agitated, forming a coating as in Fig. 2 (not shown), which is then dried preferably by rotation on a fixture in a drying environment, e.g. an air flow through a hood. The particles are generally removed from the flat surfaces, conductive fingers being selectively applied, or may remain if all substrate is to be simultaneously activated. Heating fuses the particles to a glaze, e.g. 500 to 550‹ C., or 515‹ to 520‹ C. A two-step process is used for inclined holes. Heating in a reducing atmosphere, e.g. hydrogen at 325‹ to 350‹ C., or carbon monoxide, reduces the glass. Examples give geometrical dimensions and preparation details.
