Abstract: 1,094,955. Cooling discharge tubes. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 18, 1965 [Dec. 1, 1964], No. 49022/65. Heading H1D. [Also in Division F4] In an evaporative cooling system for a discharge tube having an external anode 16 immersed in the cooling medium 22, the cooling fluid is sprayed in the form of a stream on to the surface of the anode to disrupt vapour which otherwise tends to form an insulating layer at the anode surface. As shown, tube 10 having a glass or ceramic envelope 12, has its anode 16 immersed in cooling fluid 22 in a boiler 20. The cooling fluid, pure, deionized water, is circulated through inlet pipe 32, manifold 26 and a plurality of pipes 28, which are arranged between the wedge-shaped teeth of the anode, Fig. 2 (not shown), and are formed with apertures 40, so that jets of water are directed on to the anode surface under pressure of the circulating means and carry away vapour bubbles which otherwise tend to collect between the anode teeth. The water leaves boiler 20 via outlet 34 and is pumped around a closed circuit including a heat exchanger, Fig. 4 (not shown), to return to inlet 32. The anode 16, boiler 20 and pipes 28 are of copper, and dimensions of pipes 28 and apertures 40 to obtain a water pressure of 10À5 p.s.i. are given.

Abstract: 1392998 Vehicle side light control SAINT GOBAIN INDUSTRIES 26 Oct 1972 [27 Oct 1971] 49404/72 Heading G1A In a control system for controlling vehicle side lights according to the ambient light level a photosensitive element E, positioned in a hole or slot 20 at the edge of a windscreen 110, is in direct optical communication with the material of the windscreen by being embedded in a mastic 24 having the same refractive index as the glass its optical axis (or field of view) being directed through the material of the windscreen in a direction parallel to the surfaces of the glass. The photo-sensitive element E is covered by the windscreen frame 14 and in use it receives a fraction L of the total light impinging on the whole of the exposed area of the windscreen. The photo-sensitive element's output is amplified Fig. 6 (not shown) and fed to a control circuit which activates a relay turning on the side lights when the light intensity received falls below a predetermined level. The control circuit turns off the light when the intensity of the light received passes a second higher predetermined level.

Abstract: 1485095 Centrifugal separators DORNIER GmbH 2 Dec 1975 [14 Dec 1974] 49433/75 Heading B2P A separator for removing dissolved gases from hydraulic fluid incorporates a chamber 8 which receives fluid from an inlet pipe 4 via a sharp-edged orifice place 10, the fluid passing around the chamber in a helical path and then flowing through a filter 20 and channel 26 to an outlet 28. A rotary pump 24 driven by a turbine 32 pumps the fluid from the outlet. In operation, hydraulic fluid from a supply line D, Figure 2, flows to a consumer V and returns along line R. The separator is arranged in parallel to line R on a branch line R 1 , and the turbine is driven from a branch D 1  from the supply line. Fluid entering the separator initially fills the chambers 8 and 38 (the turbine is not yet operating) and causes a float 40 to close a valve 46. The resulting pressure rise opens shut-off valve 54 (to start the turbine) and closes shut-off valve 70. When the fluid supply is shut off, the valve 70 can re-open to vent the chamber 38 to atmosphere and release the separated gases.
Patent GB-1095222-A (GB)
Title: Metallizing process
IPC: C23C14/24
Filed: 1964-12-04
Abstract: A method of simultaneously coating a plurality of articles with one or more metals comprises heating the coating metal to its sublimation temperature but below its melting point at a pressure not exceeding 10-13 mm Hg and moving the articles in the vapour to expose all their surfaces.  In forming electric resistors ceramic rods preheated to 300 DEG C. are tumbled in a revolving hollow drum in a vacuum chamber containing an Ni or Cr alloy filament heated to 1170-1220 DEG C. To maintain the composition of the vapour constant a filament is heated for only ten minutes and resistances of 1000 ohm/sq. cm. formed. To produce lower resistances several coatings using several filaments are deposited.  The rods are cooled for 10 minutes before removal from the chamber and may then be aged to vary their temperature coefficients of resistance by heating in air to 275 DEG C. for 8 hours.  Their final resistance may be adjusted by removing parts of the metal layer e.g. by grinding a helical groove in the coating. Conductive caps having pigtail wire leads may be added to each end and the rod encased in a glass or epoxy resin capsule.

[Also in Division B8] A machine for setting up, filling (see Division B8) and sealing collapsed tubular cartons comprises a series of mandrels vertically arranged on an intermittently rotatable assembly on to which the opened cartons are pushed for carriage past bottom flap folding and securing apparatus, the cartons then being transferred to holders on a second rotatable assembly passing beneath filling and top sealing means. The cartons (Fig. 22) may be as described in Specification 990,835. Bottom sealing.-The mandrel on to which a carton has been forced is indexed to a heating station where hot air jets from a nozzle 216, Fig. 9, and heater bars 213 render ahesive the polyethylene coating of the carton material. The heater mounting cradle 211 may be swung clear of the mandrels by cylinder 204 and does this automatically should the machine stop. Heat shields are provided. The carton is carried to the bottom folding station where members 237, Fig. 10, on oscillating arms 236 initiate inward folding of the triangular flap portions (56) 58 and further oscillating members 247 engage the other flaps 55 (57) so as to fold them with their projecting margins 61, 62 in overlapping relation. The folders are carried on a mounting 225 which rises beneath the mandrel and its continued upwards movement causes them to withdraw while a final seal is formed by a pressure pad 227. The pad and mandrel may be water-cooled. Sealing after filling.-The carton is transferred to a rotary filling and sealing assembly and after being indexed beneath an initial folding station and liquid filling means (both not described) passes through three heating stations in turn. The first two heating stations each comprise elements 311, 312, Figs. 18, 19, and a heat shield 306 for heating the inner surfaces of the flaps. The support 305 may be raised by means 293 and rises automatically if the machine stops. The final heater 313 has a single bar element only. The rails 285 converge to cause flaps 23, 24, Fig. 25, to approach each other during heating and the closure seal is performed by pivotal jaws 336, 346, Fig. 20, with attached guide members 351, 361 contacting the panels 23, 24 prior to sealing. Finally the carton is released on to a discharge disc 22 by a stationary guide rail (Fig. 1, not shown).

The interpolymer may be prepared in the same aqueous system used to prepare the suspension particles or if wet cake or dried suspension particles are isolated these are reslurried in water. Numerous examples of the vinyl halide monomer, the other ethylenically unsaturated monomer, and the monomer component for forming the rubbercontaining interpolymer are specified. The suspending agent may be gelatine, hydroxy methyl cellulose, hydroxy ethyl cellulose, hydroxy propyl cellulose, carboxy methyl cellulose, talc, clay or polyvinyl alcohol.
