Patent GB-473657-A (GB)
Title: Improvements in or relating to the coating of absorbent materials
IPC: D06M15/39
Filed: 1936-04-15
Abstract: In a continuous process for coating absorbent material such as paper, cardboard, textiles, and leather in long lengths with aqueous dispersions of solid water-insoluble synthetic resins, the coated material is rapidly dried at a temperature above 110 DEG  C. so that the resin is deposited as a continuous film and then hot-calendered to produce a glossy surface.  Suitable synthetic resins are polyvinyl chloride or acetate, polyacrylic acid esters, e.g. methyl methacrylate, polystyrene and polyhydric alcohol-polybasic acid resins.  The drying temperature is above the softening point of the resin and high enough to remove all the water from the dispersion on the surface of the material in 5--10 seconds.  If necessary, a further short heating at a lower temperature, e.g. 75 DEG  C. may be given to remove absorbed water. Calendering may be done on a four-bowl calender at a temperature of 125 DEG  C. and a pressure of 700 pounds per square inch.  Wax may be incorporated in the dispersion to produce a film on the coated surface which may subsequently be removed by polishing.  In the example, a dispersion is prepared by adding to methyl methyacrylate, caustic soda solution, a peroxide, dibutyl phthalate and cyclohexanone, stirring and heating to 80 DEG  C. to polymerize.  10 per cent of an emulsion of white wax is then added.

Filed: 1976-03-18
Abstract: 1517872 Drill stem stabilizers SMITH INTERNATIONAL INC [trading as DRILCO INDUSTRIAL] 18 March 1976 10942/76 Heading E1F A drill pipe or special sub 21 connected to a bit 11 is fitted at its reduced diameter lower end with a stabilizer 31 having an inturned flange 35 clamped between a shoulder on the bit and the bottom of the pipe or sub. The sleeve is in threaded engagement with the pipe or sub as at 67, 79 and carries a rubber seal ring 85 for engaging a shoulder 71 of the pipe or sub. Blades 91 projecting from the sleeve are coated with tungsten carbide granules or fitted with tungsten carbide inserts pressed into holes in the blades (Fig. 3, not shown). The bit can be of the rolling cutter, drag or diamond type. The radial width of shoulder 73 of the stabilizer should be at least twice the height of threads 79. Where a blasthole drill stem is assembled from two drill pipes, the pipes may each be adapted for connection to the bit and for fitting with the stabilizer, and in such case a spacer 35B would be fitted between the pipes as a substitute for flange 35. As an alternative, where the drill head and the bit have non- mating tool joints only one of the pipes would be adapted for connection to the bit and for fitting with the stabilizer. It is suggested that the bit might alternatively have a box joint and the pipe or sub a pin joint.

Abstract: 973,954. Electric selective signalling systems. R. SCOTT. March 19,1963 [March 22,1962], No. 10949/62. Heading G4H. In a system for measuring the pressure in a selected reaction flask 20, Fig. 1, each flask (only one being shown in the Fig.) is connected by a flexible tube 21 to one side of a diaphragm 54, Fig. 4, the other sides of the diaphragms being connected to a common manifold 11, Fig. 1, and the pressure in the selected flask is determined by lowering (or raising) the pressure in the manifold from a reference level to such a level that the pressure in the flask is just balanced by the pressure in the manifold, this being detected by the opening (or closing) of two contacts 58, Fig. 4, on the diaphragm, and the change in pressure in the manifold required to achieve balance being determined by counting clock-pulses for the period for which a synchronous motor 15, Fig. 1, has to drive a bellows 42, Fig. 3, via a clutch 16, to effect the necessary change in pressure in the manifold. The reference pressure in the manifold is determined by driving the pressure varying motor 15 until the pressure in a reference flask is just balanced. A block diagram (Fig. 6 not shown) is described in which clock-pulses derived from the A.C. mains are counted for the period for which the pressure varying motor is on and the result for each flask is printed. The actual time when the measurement is made is also printed.

IPC: F01L7/02
Filed: 1917-07-30
Abstract: 113,228. Gove, H. H. July 30, J917. Valves; valve-gear.-Rotary valvesections 25, 40 are secured together by a tongue and groove connexion 44, 45, and each controls the inlet and exhaust ports of a pair of adjacent cylinders 3, 4 and 1, 2 respectively. Mixture is delivered into the interior of the valve through end ports 28, 28<a> and through a channel, between the adjacent ends of the valve-sections, which opens into a supply passage 22 in the valve casing. The charges enter the cylinders 4, 3 when ports 29, 30 in the valve 25 register with the ports 27, 26 respectively in the heads of the cylinders. The burnt gases discharge through passages 31, which deliver into chambers leading to the exhaust pipe 36. The exhaust passages 31 are surrounded with asbestos or other material which prevents undue heating of the bearing surface of the valves. To prevent the deposit of foreign matter adjacent the cylinder ports, packing-rings carrying a cross-bar 52, Fig. 4, are housed in suitable grooves so that the bar 52 may act as a scraper. A modification is described in which each end of the exhaust passage in a valve-section registers alternately with a port leading to the discharge pipe and with a cylinder port. Each section is split longitudinally through the supply ports and provided, if required, with a spiral packing-ring 78, Fig. 9, extending throughout its length. The valve may be stiffened by internal ribs.

Filed: 1954-04-15
Abstract: 806,003. Indirectly heated cathodes. POSTMASTER GENERAL. May 9, 1955 [April 15, 1954], No. 11239/54. Class 39(3) An insulator for insulating the indirectly heated cathode of a thermionic valve from the heater is formed of a fused silica-free refractory material and provides a substantially impervious barrier which is arranged so that it extends across the electrostatic lines of force when the insulator is in use to prevent migration of charged particles or uncharged molecules of the material. If a sintered material, such as sintered alumina, is used, the barrier may be formed by fusing the material on one or other of its surfaces or throughout its thickness. Alternatively, one or more silica-free substances may be applied which react with the refractory material or with each other to give compounds which have a lower melting point than the refractory material, heat being applied to melt the compounds.
