Title: Improvements in the propulsion of vessels
IPC: B63H11/00
Filed: 1920-04-30
Abstract: 142,500. Motte, C. MC. April 24, 1919, [Convention date]. Propelling, steering, and manoeuvring by water jets.-One or more turbines are mounted in a vessel with their axes vertical and the casings are rotatable in a horizontal plane to vary the angle at which the jet is discharged so as to steer, stop, or reverse the vessel. A turbine element comprises a casing b containing radial rotating blades a mounted on a vertical shaft c. Suction openings b<1> are provided in the upper part of the casing, a central aperture b<2> in the lower part, and an outlet aperture d. The casing b is made integral with a sleeve e by means of which it may be turned to vary the position of the opening d. A single turbine may be used for propelling a vessel, or two turbines may be arranged as shown in Fig. 3, with their discharge openings d arranged symmetrically with respect to the longitudinal axis of the vessel. The turbines may be turned by means of chains g, g<1> engaging with the pinions h, h<1> integral with the sleeves e, e'. The chains are operated by intermediate pinions h<2> operated by toothed wheels h<3>, h<4> controlled by a handle i. In another form, Fig. 4, the two turbines may be superposed, and the two sets of blades may be carried by concentric shafts c, c'. The casings b, b<4> are adapted to be turned so that their outlets d, d<1> remain symmetrical. When the two outlets are 180 degrees apart, the propelling effect ceases, and when they are again parallel after a half turn, the vessel is reversed. In another form, a combination such as that shown in Fig. 4 is arranged on each side of the vessel. A rudder may be attached to each turbine casing parallel to the discharged water. In another form, Fig. 11, the turbine may be arranged in a well j within the vessel, which is provided with a water conduit m. The casing k carries a grid l to prevent the ingress of solid matter, and is displaceable vertically to compensate for variations in the draught of the vessel. Water is drawn in through the conduit j', n and discharged through outlet orifices on the opposite side. In another form, Fig. 15, the turbine may be arranged within a recess o<1> in the rudder o. In all cases, the turbines may be placed at either end of the vessel, and may be mounted on horizontal shafts so that their outlets are always in a horizontal plane.

Title: Improvements in cathode ray tubes
IPC: H01J29/50
Filed: 1940-07-23
Abstract: 553,131. Cathode-ray tubes. COSSOR, Ltd., A. C., SHELTON, E. E., and MOSS, H. July 23 1940, No. 12050. [Class 39 (i)] In cathode-ray tubes of the kind in which the beam issuing from the gun is divided by a plate 3 between the first pair of deflector plates 4, 5, as described in Specification 505,026, provision is made for making the secondary electron current between the plate 3 and one of the deflector plates independent of the potential of the other. This consists in making the plate 3 of a material of low secondary electron emission such as metal with a carbonized surface or in shielding the field on one side from the other or both. The shielding effect is obtained by extending the plate 3 in the direction of the cathode to an apertured disc 2a which is at the potential of the second anode 2 and may form part thereof. The deflector plates 4, 5 and the plate 3 are carried by mica discs 29, 30, which carry an apertured rectangular metal plate 21. The edges of the aperture parallel to the deflecting plates have turned up lips 21c, and deeper plates 22a are attached at the transverse edges. The outside edges of the plate 21 have deep flanges 21a, on which and the plates 22a rests an apertured mica disc 28 carrying a metal plate 24 electrically connected by a lead 23 to the flange 21a of the plate 21. A tubular shield 25 surrounds the deflecting plates. By these means, the plates 3, 4, 5 are shielded from the straight portions of the additional deflector electrodes 6, 7 which are cross-connected to the deflector plates, and from the supporting and lead-in rods, such as 9, 14 by which the pairs of deflector plates 4, 5 and 20 are mounted. Secondary emission from the fluorescent screen are collected by a metal sleeve 27, which has a push fit over the mica discs 28-31, and is given a potential of about 35 volts positive to the final anode through a lead 17.

Title: Microbiological processes for the production of dicarboxylic acids
IPC: C12P7/44
Filed: 1961-04-04
Abstract: A process for the production of dicarboxylic acids comprises subjecting a compound from the group consisting of hydrocarbons having terminal methyl groups, hydrocarbons having terminal methylene groups and oxidised derivatives of said hydrocarbons wherein one terminal group is partially or fully oxidised and another terminal group is unoxidised or partially oxidised, to the action of oxidising enzymes produced by the aerobic growth of a diterminal oxidising strain of a microorganism.  Suitable starting materials include aliphatic (saturated or unsaturated), alicyclic or aromatic hydrocarbons, aldehydes, alcohols, monocarboxylic acids and omega-hydroxy carboxylic acids.  The process may be effected by aerobically culturing the microorganism in the presence of the substrate or by the use of isolated enzymes. In the former case, the process may be effected during the growth phase or in the stationary phase in a medium deficient in one or more nutrients essential for growth.  In one embodiment the microorganism is cultured in the presence of a gaseous hydrocarbon such as methane or propane, natural gas or "liquefied petroleum gas" until a suitable cell population has been attained, allowing remaining gaseous hydrocarbon to escape and adding the hydrocarbon it is desired to oxidise. Specified microorganisms belong to the following genera of class Schizomycetes; Flavobacterium, Mycobacterium, Streptomyces, Nocardia, Brevibacterium and Corynebacterium.

Title: Improvements in or relating to apparatus for controlling exposures in photographic printing and reversal processes
IPC: G01J1/42
Filed: 1935-04-23
Abstract: 455,623. Photographic exposure meters. I. G. FARBENINDUSTRIE AKT. - GES., Frankfort-on-Main, Germany. April 23, 1935, No. 12190. Convention date, April 25, 1934. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 21, 1935.] [Class 98 (i)] Control of the exposure in photographic printing and reversal processes is effected by a photo-electric cell which is illuminated by light passing through a photographic image and deflects a mirror galvanometer to alter the direction of a pencil of light falling on a diaphragm of fixed shape and size so that more or less of the light is passed in dependence on the deflection. In the apparatus shown in Fig. 1, light from a source L passes through the film F and falls on the photo-electric cell A, the current from which actuates the mirror of a galvanometer G. The mirror reflects light from a source L2 through a diaphragm B and a groundglass screen D to expose the sensitive surface. The shape of the diaphragm B determines the correct ratio between the density curve of the photographic image and the gradation of exposure illumination. In Fig. 2, the sensitivity is increased by the use of auxiliary currents. The lamp L illuminates the photo-electric cell A through the film F to actuate the galvanometer G. A second cell H is in parallel with cell A, and is excited by the illuminating lamp N through the diaphragm B, e.g. behind the film F2. Residual currents due to the most dense portions of the film are made inoperative by including auxiliary cells J, K, with accompanying resistances RJ, RK to be illuminated by the lamps L, N respectively and provide counter-currents to nullify the residual currents.

Up to one half of the eutectoid beta promoters may be substituted by one or more of Mo, V, Nb, Ta up to 20 per cent in total, Mn up to 5 per cent, Fe up to 3.5 per cent and Cr and W up to 12 per cent in total, the substitution being on a proportionate basis, i.e. where the alloy contains Cu for example in amount of 10 per cent the substituting elements may be present up to the maximum indicated proportions and proportionally lesser amounts of these elements are used with lesser amounts of Cu. The alloys may be annealed by heating above the beta transus temperature until transformation to the beta phase is substantially complete and then cooled at a rate of not over 10 DEG F. per minute to below the eutectoid temperature.  The alloy may then be heated at 50 to 100 DEG F. below the eutectoid temperature to remove strains and to promote compound agglomeration after which they are cooled to about room temperature at a rate not less than that of cooling in still air.  The alloys may be hardened by heating above the eutectoid temperature until equilibrium of the alloy is substantially complete and then cooling rapidly to below the eutectoid temperature at a rate sufficient to produce a fine eutectoid structure.  The alloys may be hardened by heating above the beta transus temperature till transformation to the beta phase is substantially complete or by heating in the alpha-beta range till equilibrium is established and then cooling to below the eutectoid temperature sufficiently rapidly to produce martensite, the cooling rate being at least as rapid as an air cool in still air.  The cooled alloy may be aged at a temperature below the eutectoid temperature.

Title: Improvements in or relating to methods and compositions for nucleating alpha-olefin polymers
IPC: C08K5/098
Filed: 1969-03-11
Abstract: 1,202,835. Polyolefin compositions. DART INDUSTRIES Inc. II March, 1969 [13 March, 1968], No. 12746/69. Heading C3P. A process for preparing a masterbatch blend of a crystalline α-olefin polymer and, substantially uniformly dispersed therein, a watersoluble oxygen-containing nucleating agent, involves dissolving the nucleating agent in water, precipitating a gel-like slurry by admixing the solution of the nucleating agent in water with an excess amount of a non-solvent-with which water is at least partially miscible-for the nucleating agent, adding particles of a crystalline α-olefin polymer to the slurry, agitating to disperse the polymer particles in the slurry, and separating the solids from the resulting polymer-containing slurry. The separated solids may then be dried at a temperature of 20-60 C. and a pressure of not more than 15 inches of mercury. The α-olefin polymer may be a homopolymer of ethylene, propylene, butene-1, 3- methylbutene-1, pentane-1 or 4-methylpentene- 1, a block copolymer of ethylene and another α-olefin, or a random or block copolymer of propylene with ethylene, 3 - methylbutene - 1, pentene- 1 or 4-methylpentene-1. The nucleating agent is an aliphatic, aromatic or alkyl substituted aromatic mono- or dicarboxylic acid or an alkali metal salt thereof. The following nucleating agents are particularly mentioned: benzoic acid, sodium benzoate, lithium benzoate, sodium glutarate, lithium glutarate, sodium adipate, lithium adipate, sodium succinate, lithium succinate, sodium crotonate, t-butyl sodium benzoate, o-methylbenzoic acid, 2,4-dimethyl benzoic acid, α-naphthoic acid and trans-cinnamic acid or an alkali metal salt of trans-cinnamic acid. The potassium salts of the acids may be used. The masterbatch blend may contain an antioxidant, a stabilizer against ultra-violet light radiation, filler, slip agent or antistat. Both the polymer and nucleating agent are preferably employed in the form of a very fine powder (average size around 200 mesh) - The non-solvent may be a C 1 -C 10  alcohol, a ketone, ester or partial ester, glycol or aldehyde. The following non-solvents are particularly mentioned: methanol, ethanol, propanol, isopropanol, pentanol, hexanol, acetone and ethylene glycol. Sufficient of the masterbatch blend is mixed with a crystalline α-olefin polymer (at a temperature of 20-150 C. greater than the melting-point of the polymer) to provide 0À05-2À0% by weight of the nucleating agent. An injection moulding polypropylene containing 2-3% ethylene as a random copolymer may be treated with the masterbatch blend.
