Abstract: 273,324. Du Pont de Nemours & Co., E. I., (Assignees of McBurney, J. D. and Nollau, E. H.). June 24, 1926, [Convention date]. Drawings to Specification. Printing processes; embossing.-A leather substitute comprising a backing of textile fabric and a cellulose ester coating is provided with a waterproof, non-sticky, flexible surface film comprising casein or similar protein substance which reduces the interfacial tension in order to facilitate the adhesion of glue, paste, or inks. The surface film is preferably casein, with a softener such as a polyhydric alcohol. A suitable solution consists of 3 to 25 per cent of casein, 0.5 to 27 per cent of ammonium hydroxide, 2 to 30 per cent of glycerine, and 0.5 to 5 per cent of colouring matter, in water. Several coats may be applied, giving a final thickness of 0.0025 to 0.001 inch, but one coat is generally sufficient. In the composition given, borax or potassium hydroxide or citric acid may be used instead of ammonia, and other polyhydric alcohols, such as ethylene glycol may be used instead of glycerine. The material is also adapted to facilitate the application of gold leaf or other leaf thereto, as the coated surface is readily wetted by the shellac size used. Further, leaf may be applied directly to the material, as the casein coating is sufficiently thermoplastic to cause the leaf to adhere when stamped on by a hot tool. In printing on the coated material,. ordinary ink may be used.

IPC: H01J17/04
Filed: 1954-06-10
Abstract: 773,600. T.R. switches. FERRANTI, Ltd. June 8, 1955 [June 10, 1954], No. 17041/54. Class 39(1). [Also in Group XL(b)] In a T.R. Cell containing dielectric material (which may be fibrous or gaseous) for accelerating de-ionization, retaining means are provided for restricting said material to a part of the cell away from the initiating discharge gap. The cell shown comprises a short length of rectangular waveguide 22 carrying a pair of electrodes 11 secured between metallic spacing sleeves 10 and defining an initiating discharge gap 12 which may be a dumb-bell slot. A short sleeve 15 carrying a diaphragm 13 having an aperture sealed by a glass plate 14, and a sleeve 27 carrying a diaphragm 24 having an aperture 25 sealed by a bowed glass plate 26 are brazed into the ends of a short length of waveguide 28 and form an auxiliary cell which is brazed into the input end of the waveguide 22. A combination 16 of sealed diaphragm and sleeve is brazed into the output end of waveguide 22. The space 23 is evacuated and then filled with inert gas and water-vapour through a tubulation (not shown) passing through the wall of waveguide 28. The space 29 is exhausted through another tubulation (not shown) and filled with ionizable gas at low pressure. In operation, energy reflected from the electrodes 11 when a discharge occurs between them produces a standing-wave pattern having a voltage antinode near the diaphragm 24, so a discharge is initiated across aperture 25. The seal 26 is bowed towards the electrodes 11 to ensure that this discharge takes place in the water vapour atmosphere. Similarly, diaphragm 13 is located near a voltage anti-node of energy reflected from aperture 25. The Q valves of the aperture in diapragm 13, the aperture 25 and the initiating gap 12 are chosen to give the cell a band-pass characteristic. In an alternative embodiment the waveguide 28, sleeve 27, diaphragm 24 and window 26 are omitted and the sleeve 15 is brazed directly into the end of the waveguide 22. A quantity of glass wool or silica wool is retained in the sleeve 15 by a number of parallel wires which may be spot-welded across the end of the sleeve or may be secured to two metal strips which are spot-welded to the sides of the sleeve. The wires may be staggered to lie in two separate planes. Alternatively the wool may be retained by a mica plate sprung behind retaining studs or strips on the sides of the sleeve, or by a thin glass or quartz plate. The arrangement is such that energy reflected from the electrodes 11 produces a voltage anti-node near the diaphragm 13, so the region of maximum ionization lies well within the wool.

Filed: 1949-07-01
Abstract: Olefine chlorides or bromides are made from a mixture of an olefinic compound with another gas such as hydrogen, carbon monoxide or paraffin which would react with chlorine or bromine under the conditions of direct halosubstitution by treating the mixture with chlorine or bromine in a primary zone of a reactor at a temperature which is low enough to exclude a reaction between the halogen and the gases other than the olefine, but high enough to effect substantial additive halogenation of the olefine, and then passing the product through a second reaction zone at a higher temperature, at which halogen hydride is split off to form the desired olefine chloride or bromide.  No separation, concentration or purification takes place between the two reaction zones.  The temperature in the first reaction zone is between - 20 DEG  and 200 DEG  C. and in the second reaction zone between 400 DEG  and 700 DEG  C.
