Title: Improvements in reversible propellers
IPC: B63H3/02
Filed: 1946-07-18
Abstract: 631,526. Variablepitch propellers. VICKERS-ARMSTRONGS, Ltd., and WOOD G. July 18, 1946, No. 21575. [Class 114] In a reversible propeller for ships the hub 1 is recessed to accommodate the roots of the blades 3 formed with worm wheels 7 engaging worms 8, spindles 9 carry pinions 17 meshing with gear rings 18 and 20 on the rear of a hub 18a and an annulus 21 respectively, and the forward sides of the hub and annulus have gear rings 18b and 22 engaging pinions 26 and 23 respectively on shafts 25 and 24. The front ends of the shafts carry pinions 25, 24<SP>1</SP>, meshing with gear wheels 28, 27 formed on brake drums 281, 271, controlled by remotely operated means 30, 38. Thus, movement of a control lever at 30 operates the brake 28<SP>1</SP> bringing shaft 25 and combined wheels 18, 18b to rest, consequently the pinions 17 are made to revolve over the stationary wheel 18, thus rotating the worms 8 and hence the propeller blades 3 about their axes until each blade reaches a limit stop. The wheels 18, 18b are then caused to revolve, rotating pinion 26, shaft 25 and brake gear wheel 28, causing the brake 28<SP>1</SP> to slip. Movement of the blades in the opposite direction is controlled by the lever at 38. The freeing of the brakes is automatically controlled by a hunting gear formed by gearing the wheels 27, 28 to a differential 31 which is idle when the combined wheels 18, 18b and the annulus 21 are rotating with the propeller shaft. When either brake is applied the differential precesses, causing a shaft 32 to rotate to translate a nut 33 towards a contact 34 or 35, thereby exciting a solenoid 36<SP>1</SP> or 37<SP>1</SP> to move the lever at 30 or 38. The planet gear formed by the hub 18a, annulus 21, and pinions 17, 23, 26, is housed in a chamber 19 formed by a ring 11 which acts as a rope guard. When the propeller is fitted in conjunction with stern tube lubrication, the chamber 10 is charged with oil. The oil supply to the stem tube may also be connected to a tank via valve means actuated in unison with the operation of reversing the blades so that during this latter operation the blades will be charged with lubricating oil at higher pressure than the normal oil supply.

Patent GB-917122-A (GB)
Title: Improvements relating to electrostatic coating
Inventor: BULGIN DOUGLAS
IPC: B05B5/025
Filed: 1958-07-10
Abstract: A method of electrostatically spray coating electrically non-conductive articles comprises the step of submitting the articles to penetrating radiation in the form of a -, b -, g - or X-rays immediately prior to or during their positioning in the electrostatic field.  Such materials as rubber are thereby rendered sufficiently conductive to allow the charges carried on to the articles by the coating material to leak away to earth. The radiation may be produced by an X-ray tube or a radio-active isotope, the rays from which may be directed towards the articles within the electrostatic field, or, in the case of a continuous process, across the path of articles about to enter the field.

Title: Improvements in the purification of crude benzol
IPC: C07C7/163
Filed: 1926-09-09
Abstract: 258,576. I. G. Farbenindustrie Akt.- Ges. Sept. 15, 1925, [Convention date]. Tar oils, purifying, extracting, &c.-Crude benzol is desulphurized and otherwise purified by treatment at high temperature and elevated pressure and in presence of a catalyst with hydrogen or gases containing or producing hydrogen under the conditions of working. In an example crude benzol containing thiophene is passed in a current of hydrogen at 460‹ C. and 200 atmospheres through an aluminium-lined vessel containing a contact mass prepared by pressing a mixture of molybdic acid and zinc oxide. The product is light in colour, free from unsaturated compounds and thiophene, and gives pure benzol and a small proportion of other lowboiling hydrocarbons on distillation. In a second example, crude benzol obtained by steam distilling an oil used for washing gases containing benzol is passed in a current of nitrogen and hydrogen at 450‹ C. and 150-200 atmospheres over a pressed mixture of molybdic acid and magnesium oxide. The product is fractionally distilled into pure benzol and a mixture of other hydrocarbons of low boiling point. Contact masses specified are those immune from sulphur poisoning used in the destructive hydrogenation of coal &c., e.g. those containing molybdenum, tungsten, or chromium. The pressures are preferably over 50 atmospheres.

Title: Improvements in or relating to blasting assemblies
IPC: F42B3/06
Filed: 1946-07-26
Abstract: 614,761. Blasting devices. THOMSON, T., REID, K. C., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 26, 1946, No. 22299. [Class 9 (i)] Relates to blasting devices of the type in which a pressure-resisting container is separated from a perforated dischargehead by a closure adapted to yield at a predetermined internal gas pressure produced by a non- detonating gas - evolving charge the gases being evolved without flame as in Specification 431,935. According to the invention such a device containing a granular charge of a mixture of sodium nitrite and ammonium chloride stabilised by an alkaline is actuated by electrically fired local heating means comprising an electric black powder fuze having a sheathing of a perchlorate. A pressureresisting container 1 having a firing head 2 is separated from a discharge head 3 by a rupturable disc 4. A 460 gm. charge 7 of a stabilised mixture of sodium nitrite and ammonium chloride in the container 1 is initiated by an electric fuze 6. Insulated leads 5 of the fuze 6 are connected through terminals in the firing head to the electric circuit. The fuze 6 consists of a paper tube closed by plugs 8, 9 and 17 and containing a 20 gm. charge 11 of ammonium perchlorate surrounding a 60 grain charge 16 of black powder in a paper tube 12. A low-tension electric fuze-head 15 is embedded in the black powder. The charge of ammonium perchlorate acts as a booster, reducing the delay between closing of the firing circuit and venting of the gases from the initiated charge 7 to about 30 millisecs. Thus an assembly of a plurality of these devices may be electrically connected for simultaneous shot firing. Specification 461,647 also is referred to.

Title: Improvements in or relating to lubricating greases
Filed: 1951-09-26
Abstract: A lubricating grease comprises a lubricating oil thickened with 4.5-15 per cent of a carbon black having reticulate particles coated with 1-7 per cent, based on the total weight, of an alkali or alkaline earth metal or aluminium soap of C12-C22 fatty acids.  The carbon black, preferably acetylene black, is coated in situ with the soap which is at or near its melting point and in the liquid state. C12-C22 saturated fatty acid soaps of Ca, Ba, Al, Sr, Na and K are specially suitable. Hydrogenated fish oil acids averaging C18 may be heated with one-third the mineral oil to about 160 DEG F, lithium hydroxide solution added, and the soap dehydrated by heating to 360 DEG F. Carbon black and the remaining oil are added and the mixture heated to 420 DEG F.  Extreme pressure agents such as sulphurized or phospho-sulphurized oils, chlorinated fats or hydrocarbons, and lead soaps may be incorporated.  Mineral base lubricating oils are preferred, but synthetic oils such as polybasic acid esters, polyglycols and their ethers may be used.  The products are non-staining and oil separation is low.  Viscosity index improvers, anti-oxidants, tackiness agents, inhibitors, deactivators, and the like may be present.  Comparative physical data are given for greases containing 10 per cent lithium stearate or acetylene black and 4 per cent of the former and 6 per cent of the latter, and for E.P. greases containing different proportions of acetylene black and lithium soap together with lead naphthenate, sulphurized sperm oil and chlorinated paraffin.
