Title: Catalytic desulphurisation of gas oils
IPC: C10G45/30
Filed: 1948-06-24
Abstract: A process for the hydrocatalytic desulphurization of gas oils which is self-supporting in hydrogen and is conducted at a pressure low enough to avoid the use of special pressure-resisting steels, comprises passing the gas oil in vapour form over a dehydrogenation - hydrogenation catalyst immune to sulphur poisoning at a temperature and pressure such that the dehydrogenation of naphthenes is effected to an extent not substantially in excess of that required to convert the organically combined sulphur into hydrogen sulphide and to enable the necessary partial pressure of hydrogen in the reaction zone to be maintained.  The temperature range is preferably from 750 DEG F. to 820 DEG F., the pressure range from 50 to 200 p.s.i. and the catalyst a compound of the oxides of cobalt and molybdenum such as cobalt molybdate containing excess of molybdenum oxide supported on alumina or bauxite, although molybdenum oxide on alumina or cobalt chromate on alumina may also be used.  The reaction proceeds by dehydrogenation of some of the naphthenes to produce hydrogen in excess of that required to convert the combined sulphur present into hydrogen sulphide.  At temperatures above 800 DEG F. dehydrogenation occurs to such an extent that the product becomes increasingly aromatic, while the length of life of the catalyst before regeneration is necessary becomes shortened.  The preferred space velocity lies between 1 and 2 v/v/hr., and the preferred recycle rate for the hydrogen-containing gases lies between 2000 and 4000 cubic ft. per barrel.  The process may be p  operated at constant pressure, in which case gas in excess of that required to maintain the predetermined pressure has to be withdrawn, or the hydrogen-containing gases may be recycled to the desulphurization zone and the pressure therein allowed to rise to an equilibrium pressure at which the hydrogen evolved equals the hydrogen consumed. Tables illustrating sulphur reduction in various samples of gas oil under various conditions of temperature, pressure, space velocity, catalyst charge, and time are given.  In all cases the boiling characteristics of the products show that little molecular breakdown has occurred. Specifications 612,006, 654,152, 663,038 and 669,536 are referred to.
Patent GB-171113-A (GB)
Abstract: 171,113. Boudreaux, E., (Representative of Boudreaux, L.). Nov. 5, 1920, [Convention date]. Electrotype.-An electrotype printing-plate for reproducing engravings &c. is obtained from a mould prepared by pressing a thin lead plate into contact with the engraving, and subsequently giving rigidity to the mould until the electrotype is deposited on it by securing to the mould another layer of lead which is attached to it, by a second pressing operation, with the interposition of a layer of canvas impregnated with wax mixed with pitch or any material capable of adhering to the metal. The canvas may be replaced by wire gauze, or a perforated plate more rigid. than lead, and the meshes of the wire may be filled or covered with a plastic composition formed of wax, gutta-percha, or paraffin dissolved in turpentine, so as to form a resilient cushion between the two lead plates. The supporting lead plate may be cast on a tinned copper or brass plate, which may take the pressure of the press for applying it to the lead mould.

In a machine with fluid circulated about the stator core by a first fan or pump, some of this fluid is extracted and passed through hollow stator conductors by a second fan or pump serving solely for this purpose. Gas from the coolers 3 is passed into general circulation by fans 1, but some of the cool gas enters the stator windings at 8 and is drawn through to the space 6 at high pressure by the centrifugal fan 4 arranged in a volute whence it returns to the coolers. The conductors may be in pairs of channel sections to provide rectangular ducts, with insulators between the channels, and the channels may be obliquely cut and brazed together as in Figs. 7 and 9 to provide transposed conductors. The main terminals, Fig. 3 (not shown) may be tubular with the gas flowing both through and over the tube.

Title: Improvements in vacuum leak detection
IPC: G01L21/00

Abstract: 843,060. Detecting leaks in vacuum systems. GENERAL ELECTRIC CO. June 2, 1958 [June 5, 1957], No. 17518/58. Class 37. In a vacuum system, leaks are detected by observing the current passing through a discharge device communicating with the system and comprising a heated anode 14. Such current is markedly increased on the entry through any leak of dichlorodifluoromethane or other halogencontaining gas. To improve the steadiness of the meter a small amount of air is admitted to the vacuum system. To prevent a gradual loss of sensitivity, the pressure is kept above one micron but less than 200 microns. As shown a chamber is evacuated by mechanical pumps 5 and then by diffusion pumps 3 and air is admitted at 23. In a modification, Fig. 2 (not shown), separate valves with filters are provided for the admission of air to the chamber and to the discharge tube. Specifications 648,367 and 842,897 are referred to.

Title: Improvements in spur gearing
IPC: F16H55/08
Filed: 1942-12-11
Abstract: 561,714. Toothed gearing. ENGLISH ELECTRIC CO., Ltd., and BINNEY, E. A. Dec. 11, 1942, No. 17662. [Class 80 (i)] Relates to gearing for an electrically propelled vehicle having, an axle-hung traction motor with flexibly supported nose and a pinion., carried by the motor, meshing with a gear wheel on the vehicle axle, both toothed wheels lying to one side of the motor pivotal supports. Thus, in Fig. 1, the motor 4 is hung on an axle 2 carrying a gear-wheel 1 engaged by a pinion 3 both overhanging the motor armature and the motor suspension bearing. When the wheels rotate in the direction of the arrows, tilting takes place about an axis A-A through the centre P of the nose suspension and the lower outer edge of the suspension bearing remote from the gearing. The result is to tip up the outer end of pinion 3 and cause all the load to be carried on those portions of the teeth of both wheels nearest to the motor with consequent possibility of fracture. In the reverse direction of running, the tilting is about an axis B-B. According to the invention, the concentration of load is caused to occur at the middle part of the length of a tooth instead of at the end thereof. To this end, the flank of each gear-wheel tooth or, preferably, of each tooth of the driving pinion, is of normal shape from one end up to a point at the middle of the length of the tooth but is slightly tapered from this point, Figs. 2, 3, to the end on which the concentration tends to occur. Where tilting occurs in both directions, opposite flanks may be tapered from about the middle of one flank and about 1/3 to “ of the other flank, Fig. 6. The taper is of the order of 5.to 10 minutes of angle and is produced by grinding.

Abstract: 876,913. Rotating lens turrets. PYE Ltd. June 5, 1958 [June 5, 1957], No. 17894/57. Class 97(1) [Also in Group XXIV] In an indexing mechanism, particularly for rotating the lens turret of a television camera between successive locked positions, a driven shaft 3, Fig. 1, which may be geared to the lens turret, carries a crank pin 5 engaged by a fork 2 on an offset driving shaft 1. The length of the crank arm 4 is substantially equal to, or very slightly longer than, the distance between the axes of the driving and driven shafts so that after each full turn of the driven shaft 3 the pin 5 is substantially aligned with the driving shaft 1, thereby locking the shaft 3 in position. A flat 7, Fig. 2, may be provided on the underside of the pin 5 to prevent sticking as the locking position is approached. In order to initiate movement of the shaft 3, the arm 4 may have an additional small crank pin 6 which is engaged by the fork after a degree of lost motion. The pins 5, 6 are adjacent and may be rotatable in the arm 4 or may be integral with each other. In a modification the pin 5 is mounted in a radial slot in the arm 4, Fig. 3 (not shown), and is spring loaded outwardly, thus obviating the need both for the pin 6 and the flat 7. The arms of the fork 2 may be parallel, but are preferably divergent as shown. They may be made in two pieces and may, or may not. be shaped as shown to fit the crank pin 5. When the mechanism is employed, Fig. 4 (not shown), for indexing a camera turret the shaft 3 carries a gearwheel driving the turret while the shaft 1 is provided with a detachable handle and is formed with a pinion driving an indicator gear. It is stated that the output from the shaft 3 may, instead of a complete revolution, be a motion through a given angle and back again if the shaft 1  is reversed, and may be geared up or down.
