Title: Improvements in cells with quicksilver cathodes for the decomposition of alkali-metal chlorides
IPC: C25B15/00
Filed: 1927-03-30
Abstract: 269,513. Gerlach, F. April 17, 1926, [Convention date]. Mercury - electrode apparatus; alkalies, hydrogen, and chlorine, obtaining.-In a cell for the decomposition of alkali metal chlorides of the kind in which a body of mercury circulates between the electrode chamber and an amalgam decomposition chamber at a lower level, the transfer of the mercury to the electrode chamber is effected in the presence of liquid and without shock by means of a vertical or inclined continuous or interrupted worm I having above it a horizontal disc, which may in some cases rotate with the worm. To prevent irregular motion the inner walls L of the electrode chamber are formed of smooth material such as polished granite. The inner walls of the decomposition chamber may be. similarly formed, though this is not essential. As a result of these measures a plate-shaped carbon anode may be placed within 5-10 mm. of the mercury without possibility of shortcircuiting. The electrode chamber is provided with a chlorine outlet G, and the decomposition chamber with a water-sealed bell M having a. hydrogen outlet H. The electric connection to the mercury is made by a copperplate inset in the floor of the electrode chamber. The decomposition of the amalgam may be accelerated by the introduction of grids of iron, graphite, or alloys. of vanadium or molybdenum. The body of the cell 0 may be of concrete. In a modification, the electrode chamber and the decomposition chamber are separate vessels connected by end troughs.

Title: Improvements in or relating to the Continuous Dehydration and Distillation of Tar, or other Liquids and to Apparatus therefor.
Inventor: WILTON THOMAS OWSTON
IPC: C10C1/06
Filed: 1918-05-28
Abstract: 127,700. Wilton, T. O. May 28, 1918. Progressive evaporators; hydrocarbons, distilling. - Tar and other liquids are dehydrated and distilled by passage through a series of units each consisting of a coil in which the liquid is heated to a suitable temperature under pressure, and an expansion chamber in which the pressure is suddenly released so as to produce vaporization of the lighter constituents. The tar is preheated, and is pumped, under a pressure of 30-50 lb. per sq. in., through a coil 1 heated to 160-190‹ C. The heated tar enters an expansion chamber 3 through a spring-relief valve, and the reduction of pressure causes the water and light oils to vaporize. The vapours escape by a pipe 8 to condensers 9, 14 in which light oils and naphtha respectively are collected. The residues are pumped, under a pressure of 30-50 lb. per sq. in., through a coil 2 heated to 230-300‹ C., and enter an expansion chamber 4. The resulting vapours are led by a pipe 18 to a first creosote condenser 19. The residues are led to a vessel 6 in which dstillation is effected by free steam of about 300‹ C. The vapours are led by a pipe 22 to condensers 23, 28 in which anthracene and second creosote respectively are collected. The residual pitch is led to a cooler 31. The tar is preheated by use as cooling-agent for the condensers 28, 23, 9 and the cooler 31. The heating-coils 1, 2 may be arranged concentrically so as to be heated by the same furnace, the hot gases passing over the coils 2, 1 in succession. Bvpass arrangements under thermostatic control provide for regulation of the temperature.

Title: Improvements in suspension systems for vehicles
IPC: B60G21/055
Filed: 1945-04-10
Abstract: 599,147. Vehicle undercarriages; springs. JULIEN, M. F. A. April 10, 1945, No. 8868. Convention date, March 24, 1943. [Classes 103 (vi), 108 (ii) and 108 (iii)] A suspension system for the bogies of railway and other vehicles in which the two sets of wheels are carried by longitudinal pivoted arms acted on by resilient means, comprises two transverse beams arranged at least partly one within the other and connected together by resilient cushions which allow relative movement of the beams about a transverse axis, one of the beams beings connected to the vehicle chassis and the other supporting the pivots of the arms. As shown, arms 5 carrying axles 7 are mounted in bearings 25 in a transverse U-shaped member 1 and are splined to torsion bars 9, the inner ends of which are bolted or riveted to coaxial tubes 10 secured at 12 to the member 1. Rubber buffers 30 prevent excessive movement of the arms. Rubber sleeves 24 and 28 are provided in the bearings 25 and the mountings for the axle boxes 6 to allow lateral movements of the axles, such movements being limited by the compression of end portions 29 on the sleeves. The supports 31 for the brake shoes 32 are secured to the arms, and, to minimise the couple applied to the member 1 when the wheels are braked, the axes of the bearings 25 are relatively close together. To allow movement of the member 1 in response to the braking couple, it is resiliently connected to a subsidiary T-shaped member 13 mounted on the chassis by a central pivot 14, 15 and slides 16. The resilient connection comprises rubber blocks 20, 21 bonded to opposed faces of the two members and adapted to be stressed in shear to allow relative movement of the members about an imaginary axis C (see Fig. 1 (not shown)). Further relative movement about a longitudinal axis G<1>, Fig. 6, is permitted by similar rubber blocks 23 bonded to inclined faces 22 of the members. Reaction links may be connected between the member 1 and supports 31. The suspension may incorporate hydraulic, pneumatic or friction-type shock absorbers, and the torsion bars may be replaced by leaf or helical springs. The arrangement shown is stated to produce an anti-rolling effect since, for equal movements of the wheels, both the bars and tubes are stressed in torsion, whereas, for unequal movements of the wheels, the bars only are stressed.

Title: Improvements in or relating to the production the antibiotic griseofulvin
Inventor: RHODES ALAN
Filed: 1955-03-28
Abstract: Griseofulvin, an antifungal antibiotic useful in agriculture, is produced by the submerged aerobic fermentation of a griscofulvia-producing organism in a culture medium containing an assimilable source of nitrogen at a level of 0.04 to 0.30, and preferably 0.075 to 0.25, per cent available nitrogen, a source of carbon and energy and nutrient salts.  The nitrogen source may be sodium nitrate but preferred are complex organic nitrogen containing materials such as corn steep liquor, cottonseed meal, oatmeal, soya bean meal and milk products such as whey powder, buttermilk and liquid whey.  The carbon source is preferably a carbohydrate especially lactose, glucos, sucrose or starch, used in quantities of at least 3.5 and preferably 5.0 per cent.  The nutrient salts include: (a) phosphates, e.g. potassium mono- and dihydrogen phosphate in quantities of 0.4 to 0.8 per cent; (b) calcium carbonate in quantities of 0.4 to 1.2 per cent to buffer the fermentation broth; (c) chloride ions in the form of soluble chlorides, e.g. potassium chloride in quantities of at least 0.1 per cent to prevent the formation of dechloro griseofulvia; and (d) magnesium ions.  The medium is initially adjusted to pH 4.5 to 5.5 and is preferably inoculated with a vegetative inoculum in proportions of 1 to 10 per cent of the medium, the inoculum being prepared with a medium containing less than 0.25 per cent available nitrogen.  The fermentation temperature is 25 DEG  C. and aeration is good. Fermentation is stopped before the mycelium breaks down and the griseofulvin is recovered from the mycelium by extraction with an organic solvent such as ethyl acetate, amyl acetate, butyl acetate or n-butanol.  The extract is concentrated in vacuo before 50 DEG  C., the solid removed, washed with solvent and purified by dissolving in a solvent such as acetone and precipitating the griscofulvin by the addition of water.  The medium used in the example contains corn steep liquor solids 0.2 per cent, lactose 7 per cent, limestone 0.8 per cent, potassium dihydrogen phosphate 0.4 per cent and potassium chloride 0.1 per cent.  The organism is Penicillium patulum Bainier Thom (4640, 455) C.M.I. 39,809 and this strain or mutants thereof is preferred, although other griseofulvin-producing organisms are specified.

Convention date, March 25, 1931. [Class 38 (iii).] A traction motor A with its series field in two parts H, K, is accelerated by closing contactors 1, 2, 5, and then excluding resistance R1. Thereafter contactor 6 is closed and contactor 5 opened, so that the part H of the series field is included in circuit with an exciter a, b, having a field e, f, carrying the motor armature current, and a field c, d, excited at adjustable values. By increasing the energisation of the field c, d, the motor A is regeneratively braked. If desired the contactor 2 may be opened and the contactor 7 closed so that the field H and exciter a, b, are in a local circuit. The exciter armature may be connected in the loop circuit p. The exciter may have a single field energized by series pilot exciters the fields of which are energized by a separate source, and by the motor armature current respectively. As another alternative the exciter may have a field energized by the main motor current, and its armature connected in series with an adjustable voltage. Two or more traction motors each excited in the same way as the motor A may be arranged for parallel-series transition with a transition resistance connected between the motors. After changing from parallel to series connection, and regeneratively braking as far as possible, a change to rheostatic braking may be made. With more than one motor connected in series the part H of the series fields may be excited in series from one exciter. The energizing circuit for the part H of the field of a motor may also include a voltage obtained from a separately excited exciter driven by the vehicle. The part H of the field winding of the motor may be shunted during the period of direct series excitation, and an inductance coil may be connected across the main current field coil e, f, of the exciter.
