Abstract: 986,062. Frequency detectors. HAZELTINE CORPORATION. Jan. 19, 1962 [Jan. 24, 1961], No. 2080/62. Drawings to Specification. Heading H3A. F.M. waves are limited to rectangular form and applied through a cathode follower to shock excite the tuned anode circuit of a grounded grid valve thereby producing damped groups of fixed frequency oscillations, corresponding to each cycle of the F.M. wave, which are applied to the grid of a valve, which becomes self-biased to cut-off by the first position-going half-cycle of each oscillation group. The anode circuit of the valve integrates the peaks of the first halfcycles of each oscillation group, to derive a demodulated signal. The F.M. wave may be a subcarrier of a multiplex or stereo F.M. system.

Title: Shock absorbing devices

Filed: 1971-01-16
Abstract: 1377221 Highway crash barriers DUNLOP Ltd 13 Jan 1972 [16 Jan 1971] 2202/71 Heading E1G [Also in Division F2] A shock absorbing device for mounting a highway crash barrier (not shown) comprises a deformable member (ductile steel tube 30 or tubes 7, 8 or plates 17), and a primary deforming means (plunger 5 with enlarged head 6 or ball-bearings 16) and a secondary deforming means (a rigid sleeve 31 surrounding and moving with the plunger or a sleeve 9a, 10a or layer 19 of elastomeric material) acting on opposite surfaces of the deformable member. A shock load applied to the device causes the deformable member to be deformed by the primary deforming means and subsequently redeformed by the secondary deforming means. In Fig. 1, an axial shock load causes the head 6 of the plunger 5 to deform the tubes 7, 8. Since the elastomeric sleeve 9a, 10a is confined and therefore substantially incompressible, as the plunger moves on and forms another bulge in the tubes 7, 8, the preceding bulge is forced out by the elastomeric sleeve 9a, 10a. On a transverse load ball bearings 16 deform a plate 17, which is re-deformed by the elastomeric layer 19. In Fig. 3, the head 6 of the plunger 5 expands the ductile tube 30 and then the tapered end of the sleeve 31 squeezes it back into shape.

Patent GB-450857-A (GB)
Title: New or improved process of removing tin from niobium alloys
IPC: C22B34/24
Filed: 1935-01-24
Abstract: Niobium alloys containing silicon in amount at least equivalent to that required to form the silicide CB2Si are freed from tin by treatment with a solvent for tin, which may be sulphur chloride or hot caustic alkali, but is preferably an acid such as hydrochloric acid.  Alloys containing too little silicon may be alloyed directly with silicon to render them amenable to treatment, or the required silicon content may be obtained by reduction of silica with a stanniferous niobium oxide ore.ALSO:Niobium alloys containing silicon in excess of a ratio of one part of silicon to six and a half parts of niobium are wholly or partially freed from tin by treating them, preferably in a comminuted condition, with a solvent for tin, which may be sulphur chloride or hot caustic alkali, but is preferably an acid such as hydrochloric acid.  The minimum silicon-niobium ratio corresponds to that present in niobium-silicide Nb2Si, and tin may be removed from alloys originally containing less silicon by increasing their content of silicon prior to treatment with acid. The alloys for treatment may be obtained by with smelting stanniferous niobium oxide ores a reducing agent such as carbon, aluminium, or silicon, and the required silicon content may be obtained by reduction of silicon with the ore or by alloying a niobium alloy with silicon.  In examples, the alloys treated contain, in addition to niobium, tin, and silicon, mainly iron and tantalum.

Title: Improved process for the purification of mineral oil distillates and of paraffin wax
IPC: C10G25/00
Filed: 1926-01-27
Abstract: 260,455. Burmah Oil Co., Ltd., and Worsley, R. R. le G. Jan. 27, 1926. Purifying mineral and tar oils, and paraffin wax.-Fractions of petroleum, shale oil, coal oil, or the like, and paraffin wax are refined by passing the vapour under reduced pressure through fuller's earth, bauxite, silica gel, or other adsorbent at a temperature not substantially more than sufficient to maintain the vapour phase. The vapours may be passed in succession through adsorbent of increasing strength. Treatment with sulphuric acid, or with alkali, or with both may precede treatment with adsorbent, and this successive treatment may be repeated any number of times. The action is accelerated by passing a current of inert gas insufficient to affect the vacuum materially along with the vapours. In an example, a 160-225‹ C. kerosene fraction is treated with sulphuric acid of 10 per cent strength, and passed into a fuller's earth chamber under a vacuum of 27 m. of mercury and heated by steam to about 140‹ C. Suitable apparatus comprises a jacketed vertical tube with the upper 5/6 packed with adsorbent and connected at the top to a condenser and vacuum pump. Liquid oil is run into the empty lower portion, preferably through a narrow central tube from the top, or vapour is introduced from an external still.

Abstract: 534,367. Synthesis of hydrocarbons from carbon monoxide and hydrogen. POTTS, H. E. (Naamlooze Vennootschap Internationale Koolwaterstoffen Synthese Maatschappij. (International Hydrocarbon Synthesis Co.)). Feb. 8, 1940, No. 2406. [Class 2 (iii)] [Also in Group III] Hydrocarbons with more than one carbon atom are prepared by catalytic conversion of carbon monoxide with hydrogen using catalysts which contain cobalt together with from 0.2 per cent to 8 per cent by weight of silver, which have previously been subjected to a reducing treatment in the reaction vessel at a temperature not exceeding 250‹C. The silver may be present as such or in the form of a compound. The catalyst may also contain further constituents such as iron, nickel, and promoters such as the oxides of thorium or magnesium, or mixtures thereof. A preferred way of preparing the catalyst is to precipitate the cobalt and silver together from mixed solutions of their salts. Carriers such as diatomaceous earth may also be present. In examples : (1) Potassium carbonate is added to a solution of cobalt and silver nitrate to which diatomaceous earth has also been added. The precipitate is dried at 110‹C. and is reduced with hydrogen at 220‹C. in the reaction vessel. Subsequently a stream of carbon monoxide and hydrogen is passed through the vessel at 190‹C. under 12 atmospheres pressure. (2) A catalyst comprising cobalt, silver, thorium oxide and diatomaceous earth is produced as in example (1) and carbon monoxide and hydrogen passed over as before.

Abstract: 810,399. Thermionic valves. MACHLETT LABORATORIES Inc. Jan. 23, 1957 [Feb. 2, 1956], No. 2451/57. Class 39(1). An electrode such as a cage-like grid is fixed to a flexible annular member mounted on a support, portions of the annular member being individually adjustable to tilt the electrode about a point on its axis coplanar with the annular member. In the form shown, the grid consists of support wires 29 round which is wound the helical grid wire 33. The support wires 29 are secured to a tubular shield 30, whose lower end is flanged outwardly at 34 and then inwardly again as at 35, and screwed to a supporting ring 37. The flanges 34, 35, with the joining portion 36, form an annular rib, the walls of which can be flexed towards each other. Spaced round this rib are a number of screws 40 which pass through holes in the flanges 34, 35 and thread into the ring 37. Figs. 4 and 5 show how, by adjusting the screws 40, the flanges may be pressed together, so tilting the upper part of the shield 30 and consequently the attached grid supports 29, thus affording a more precise control over grid-to-cathode positioning. The cathode is of the multiple-filament type, the filaments 21, 24 being attached alternately to plates 18 or 20 which are connected to respective terminal posts 15, 15a. The plates also support a stem 43 carrying a heat shield 44.
