Title: Improvements relating to anodes for use in electrolytic protection systems
Inventor: MORGAN JOHN HAROLD
IPC: C23F13/02
Filed: 1956-10-31
Abstract: 880,519. Preventing corrosion. CATHODIC CORROSION CONTROL Ltd. Oct. 28, 1957 [Oct. 31, 1956; Jan. 25, 1957(2)], Nos. 33312/56, 2853/57 and 2854/57. Class 123(1). In an impressed current cathodic protective system for an immersed metal structure 6, the anode consists of a stranded or solid core 2 of tinned copper wire, or where the anode is to be slung as a catenary beneath, say, a pier, of steel wire, on to which is extruded by cable making machinery a covering 4 of a lead alloy, the alloy cover being coated with a hard, durable, electrically-conducting film 12 of lead peroxide which is formed during the initial operation of the system by the action of the oxygen liberated at the anode. The coating prevents corrosion of the alloy and thus enables higher current densities to be used during subsequent operation. The hardness, durability and adhesion of the film is due to the inclusion in the base alloy 4 of one or both of the metals silver and antimony, a preferred alloy composition being 93 % lead, 1% silver and 6% antimony.

Title: Improvements in or relating to hobbing machines
IPC: B23F23/12
Filed: 1962-08-31
Abstract: 1,013,718. Gear-cutting. M. PFAUTER, G. PFAUTER, H. PFAUTER, and W. PFAUTER, [trading as FIRM HERMANN PFAUTER]. Aug. 31, 1962, No. 33480/62. Headings B3B and B3K. A hobbing machine comprises flywheels connected through spring means to the hob and work-table shafts, two measuring devices for measuring the relative angular rotation between each mass and its associated shaft, means for comparing the outputs of the measuring devices, and an adjusting device for automatically modifying the drive to the shafts to maintain a substantially constant ratio between their rotational speeds. The measuring device 11a on the cutter shaft 4 has a casing 12 containing a flywheel 14 on a spring support 13, any difference between the angular positions of the wheel and casing causing a signal to be transmitted through a wire 17 to a comparator 19. The comparator also receives a signal from the device 11 on the work-shaft and compares the signals against means corresponding to the ratio of the speeds of the shafts. A signal is then transmitted to a device 21, causing a modification in the drive 23 to the work-table. A similar device may modify the drive to the cutter. In a modification, the work-table is rotated by a constant-speed motor and the device 21 controls a second motor to modify the drive through a differential gear. Alternatively, an electricallycontrolled slip coupling may be used. Additional correction may be superimposed by a rotating template 32 to compensate for errors in the worm drive to the work-table. At high rotational speeds of the table, a filter 36 provides a further correction to take account of the effect of the flywheel masses in correcting fluctuations. A further electrical device may take account of oscillation effects of the flywheel system. In another modification, the device 21 corrects the drive by moving the cutter-shaft or the table worm-drive shaft axially. Instead of electric signals, fluid-pressure or mechanical signals may be used.

Abstract: 1318153 Burning noxious vapours; heating gases for drying GRANCO EQUIPMENT Inc 16 July 1971 [29 July 1970 8 Jan 1971 (2)] Headings F4B F4G and F4S A fume incinerator comprises an elongated combustion chamber, a mixture of fumes and air passing over the outer surface of the combustion chamber, and being supplied to the combustion chamber at an increased pressure to burn therein. In a fume incinerator mounted in a casing 16 above a drying oven 12, fumes pass into a chamber 25 at one end of the casing, and through a U-shaped casing 30 surrounding a U-shaped combustion chamber. A fan 32 in a chamber 25a forces the preheated fumes into one straight limb 40 of the combustion chamber at an elevated pressure, and the fumes burn in the chamber after ignition by a burner 38 before passing out to the stack 50. The straight limbs 40, 46 of the combustion chamber are formed of panels 62 with flanges 64, Fig. 3, secured together with fin members between them. The outer fins 76 space the combustion chamber from the shell 30. Recirculation of the burnt gases may be provided through holes 82 in the second straight limb 46 of the combustion chamber. The combustion chamber is of light metal, and any buckling of its walls increases the turbulence of the gases. Leakage between the panels 62 increases the recirculation. Part of the atmosphere of the oven may be recirculated over the outside of casing 30, past a trim burner through a fan to the oven. The elongated combustion chamber may be of annular form, with preheat chambers within as well as outside it.

Title: Method of performing chemical, metallurgical, and other industrial processes by means of an electric glow discharge
IPC: H01J37/32
Filed: 1957-10-28
Abstract: 868,708. Treating gases with discharges. ELEKTROPHYSIKALISCHE ANSTALT B. BERGHAUS. Oct. 28, 1957 [Oct. 27, 1956], No. 33589/57. Class 39(1). In a method of carrying out chemical or metallurgical processes in gases under the action of an electrical glow discharge, a zone of lower pressure is created in a zone of higher pressure by the action of flowing gas, or by localised heating, or by both, the electric discharge being maintained in the zone of lower pressure by means of an electric field superimposed on this zone. In Fig. 1 the intensity of the discharge produced between hollow tube 22 and inner electrode 25 is increased until the temperature within tube 22 reaches 1000 to 2000‹C. The inner electrode 25 may be cooled by circulating fluid. The pressure in chambers 20 and 21 is then adjusted from 10 mm. Hg. to 250 mm. Hg. The high temperature within tube 22 may be attained by heating the electrode 25 by means of an electric resistance heater. In another embodiment the outer tube 25 is provided with annular channels and a hollow cathode discharge is formed in them. The gas may be supplied through the inner electrode 25 which is hollow and apertured for the purpose. In Fig. 4 the gas is supplied to an annular recess 36 in a body 34 and emerges through nozzle-like radial ducts 38 into the reaction space in the form of gas jets. An intense electric discharge is set up to raise the temperature. In Fig. 5 a gas jet introduced through a nozzle 40 creates a zone of lower pressure within the tube 42, and the gas for entering into the reaction is introduced through radial nozzle openings from an annular duct 46. The gas jet may comprise an inert gas or a gas also entering into the reaction. The electric discharge is formed between a ring electrode 43 and the tube 42.

Title: Improvements in or relating to decorticating fibrous materials
IPC: D01B1/22
Filed: 1929-11-06
Abstract: 342,759. Decorticating siza1, hemp, &c. COOKSON, G. E., 28, Station Road, Marlow, Buckinghamshire. Nov. 6, 1929, No. 33741. [Class 120 (i).] In a machine for decorticating fibrous material, a number of conical rollers are mounted so as to exert a crushing action upon the fibrous material as it passes between them by arranging them in pairs in any manner not claimed in Specification 328,757, [Class 120 (i), Spinning, Preparation &c. for]. Fluted parallel breaking rollers 2 pass sizal &c. to pairs of conical crushing rollers 3a, 3b, 4a, 4b, the upper roller 3a of the first pair being smaller than the lower roller 3b and the upper roller 4a of the next pair larger than its lower roller 4b ; this alternation continues throughout the machine. The large rollers are mounted with their large ends disposed alternately at opposite sides of the machine and all the rollers in the top row taper in one direction, which is opposite to the taper of the rollers in the bottom row. This arrangement compels the material to follow a zig-zag path, the " true centres," i.e. the places where the rollers of a pair are of equal diameter, being out of alignment, and promotes a rubbing action which is intensified by spiral grooves in the rollers. Both upper and lower rollers rotate at uniform speeds. Between the upper rollers and also between the lower rollers are conical feed rollers 18 tapering opposite to, but rotating in the same direction as, the rollers with which they co-operate and perforated for the passage to the material of water from a main 24 which also delivers water through pipes 26 direct to the material. In modifications, the shafts of the rollers may carry more than one roller or sets of rollers in pairs may be mounted upon one another to save space. Instead of the rollers of a pair being mounted with their tapers in opposite directions, they may be mounted to taper in the same direction and be driven at different speeds.
