Filed: 1959-04-24
Abstract: A synthetic crystalline zeolitic molecular sieve, designated zeolite T, of formula 0,7-1,5[xNa2O:(1-x)K2O]Al2O3: 6,4-7,4SiO2:0-8H2O, where x is 0,1 to 0,8, and having a specified x-ray diffraction pattern is prepared by forming a sodium/potassium aluminosilicate mixture of composition either <TABS:0912936/III/1> or <TABS:0912936/III/2> and maintaining the mixture at 100 DEG -150 DEG C. until the zeolite crystallizes.  The zeolite should be activated by heating to 300 DEG C. under atmospheric or reduced pressure or by maintaining at room temperature under vacuum.  The activated zeolite preferentially adsorbs polar, unsaturated or straight chain hydrocarbons. Comparative data is given for the adsorption capacity of the zeolite for water, oxygen, argon, propane, propylene, n-pentane, cyclopropane, iso butane, thiophene, benzene, carbon dioxide, butene-1, ammonia, krypton and cyclohexane.  The zeolite may be pelletted with clay.

Title: Improvements relating to hydraulic and other fluid pressure couplings
IPC: F16L29/00
Filed: 1925-05-28
Abstract: 241,128. South Metropolitan Gas Co., and Fletcher, C. U. May 28, 1925. Couplings, disconnectible; with valves; cup-leather joints.- The two members A, B of a fluid-pressure coupling are released by means of a safety catch F, pivoted to the body A at E, so arranged that two movements thereof are necessary, the first movement permitting a slight withdrawal of the member B and the automatic shutting off of the fluid, by means of a valve N positioned within the member A, the second movement freeing said member B and allowing it to be withdrawn. In order to couple the members, the operations are reversed. The catch F is provided with a cover plate G, while movement of said catch is limited by a pin H fast on the body A and passing through a slot K in the catch. The catch F is also provided with a cam slot L of such shape that when the catch is in the position shown in Fig. 1 it engages a flange D on the member B and prevents withdrawal, while, when it assumes the position shown in dotted lines, where the flange D is clear of the slot L, it allows the member B to move outwardly until the flange D is engaged by the cover plate G. The plate G is provided with a slot M also, arranged to engage the flange D when the catch proper does not and vice versa, so that by now returning the catch F to its original position the member B may be completely withdrawn. The slidable valve N, which is opened by contact with the member B, is provided with ports O, and during the first of the above movements of the catch F, when the member B is partially withdrawn, it is moved by the fluid pressure until it comes in contact with a seating on the body A so that the ports 0 are closed. Fluid-tightness between the two members is secured by a cup-leather packing C, while the pipe B is provided with ports Q for passage of the fluid.

A receiving aerial suitable for use with television frequency signals comprises two flexible elements of a length substantially less than #/4 which are connected together at one end of each by a tunable inductor whereby the aerial may be selectively tuned to receive signals over a particular channel. The other ends of the elements are left open and coupling means to match the aerial to feeder and receiver input, are associated with the inductor. In a preferred embodiment each of the elements 1 consists of two parallel conductors 3 contained within the ends of a dumb-bell sectioned flexible ribbon of insulating material 2. The elements are secured at their inner ends to an insulating base 5 and both conductors 3 soldered to terminal tags 4. A cylindrical pillar 6 supports the inductor coil 8, connected between the tags 4, on its outer surface. The inside of the pillar is screw-threaded and contains a threaded core 9 of bonded powdered iron adjustable in position to tune the aerial. A brass core may be used instead of the powdered iron core for a different waveband, or a composite core, half of one material and half of the other may be used. The inductor serves as the primary winding of a matching transformer, a secondary winding 13 of a suitable number of turns for matching the aerial to the feeder being wound over the top of it and connected to the feeder 15 at terminal tags 14. Alternately a part of the winding 8 may be tapped off for connection to the feeder so that the operation is that of an auto-transformer. A dust cover 16 is provided to enclose the coils and connections.

Abstract: 1423485 Oxidative removal of impurities from acetic acid UNION CARBIDE CORP 1 April 1974 [2 April 1973] 14431/74 Heading C2C The concentration of oxidizable impurities, comprising alpha-, beta-unsaturated ketones, in acetic acid is decreased by contacting with a gas containing molecular oxygen at elevated temperature (e.g. 75-150 C.) in the presence of a catalytically effective amount of a transition metal compound for a sufficient period of time to decrease the concentration of impurities to such a level that the permanganate test time for the acid after distillation is at least 2 hours. The transition metal compound may for example be an alkanoate (acetate) of Mn, V, Co, Ni, Mo, Fe, or W. The molecular oxygen is preferably used at about 2-14% in a mixture with inert gas. In the examples the product is distilled and a major fraction constitutes the required product; a forecut containing impurities is rejected and the residue containing the catalyst may be recycled for further use, The impure acetic acid may be the product of liquid phase oxidation of hydrocarbons, e.g. of butane.
