Title: Improved method of forming teeth on combs for hand-pieces of machines for shearing filamentous formations
Inventor: SPENCER CHARLES HADDON
IPC: B24B3/58
Filed: 1955-02-22
Abstract: 792,082. Grinding toothed combs. LISTER & CO., Ltd., R. A. Jan. 13, 1956 [Feb. 22, 1955], No. 5283/55. Class 60. The teeth of a comb for a hand-piece of a machine for shearing hair, wool or other filamentous formations, e.g. a sheep shearing machine or a horse clipping machine, are formed by grinding ; a ribbed grinding wheel associated with a crushing roller is used to grind simultaneously a series of equally-spaced non- adjacent gullets to form the adjacent one sides of the teeth which flank them, and a second grinding wheel associated with a second crushing roller is used to grind simultaneously a second series of equally spaced non-adjacent gullets having the same spacing as the first series, and so on with further grinding wheels as necessary until both sides of all of the teeth have been ground. As applied to a sheep-shear comb having ten wedge-shaped teeth, the 1st, 3rd, 5th, 7th and 9th gullets are operated on by a ribbed grinding wheel formed by the crushing roller of Fig. 1 thus forming teeth sides 12, Fig. 2. The 2nd, 4th, 6th and 8th gullets are then operated on by a second ribbed grinding wheel formed by the crushing roller of Fig. 3, thus forming teeth sides 16, Fig. 4. To produce wedge-shaped teeth, the comb is held at an angle, e.g., 33 degrees, to the line of traverse 14 of the grinding wheel, Fig. 5. The two grinding operations may be carried out in the same or in separate machines : in the latter event, transfer jigging is used. A slave and master crushing roller may be provided at opposite ends of the bed of each machine ; the master roller is used to form a grinding surface on the grinding wheel when it has worn beyond acceptable limits. Before further grinding of combs the slave crushing roller is ground to correct form by means of the newly dressed wheel and becomes the new master.

March 4, 1919, Spinning, doubling, and twisting machines with twisting- arrangements at delivery; winding-machines; clearing-apparat u s ; driving - arrangements; thread-guides; stop-apparatus, non-automatic.-A machine for twisting doubled yarns, or yarn from roving bobbins, or for imparting additional twist to yarn, and for winding the twisted yarn in cheeses or on doubleflanged bobbins, comprises driven spindles a, similar to mule spindles, which carry the yarns to be twisted, and swing- frames b which carry the spindles for the tube or bobbin on which the yarn is to be wound, and are so weighted as to ensure a steady pressure of the cheeses or bobbins on the driving-drum. The frame b, Fig. 7, is adjustably mounted on a rod b<3> by set-screws b<4>, and is provided with an arm b<6> carrying a bar d, which slides on a bowl d<x> and is' weighted and locked by a weighted lever e. The frame can rise in accordance with the growth of the cheese, or can be raised by drawing out the bar d, but is maintained in any position by the lever e. The yarn passes from the twisting-spindles through a flat clearer-plate i<2> over a guide-pulley to a traversing-guide h. The guide is provided with a finger h<1>, Fig. 6, around which the yarn is passed, and channels h<2>, h<3> into which the yarn automatically runs when the traverse begins. The traverse bar may be oscillated by a cam f<4x>, Fig. 9, the bowl being adjustable towards and from the centre. The spindles are driven by cords, and the drums by gearing from a shaft a<10>, which carries two sets of fast and loose pulleys, one being driven by an open and the other by a crossed belt, whereby the spindles may be driven for twist or weft. To prevent reverse driving of the drums when changing the direction of rotation of the spindles, a gear i<x>, Fig. 11, on the tin-roller shaft a<10>, which normally gears directly with the first spurwheel 2 of the drum gearing, may be moved longitudinally of the shaft a<10> and drive the wheel 2 through a pinion 11 on a swing bracket 13. A knee brake a<8> may be fitted to each twisting- spindle. In the Provisional Specification, it is stated that mechanism which permits the rising of the bobbin frame, but maintains a uniform pressure, may comprise a cam-motion or link system, or a weighted lever pivoted on the rail which ordinarily supports the catch and engaging a slotted upstanding arm on a swing frame of known type that carries the bobbin, or a lever arm carrying a cam-lever which effects the locking and weighting, and a pin which rests on a curved lever; it is further stated that split drums may be used.

Title: Improvements in and relating to treatment of surfaces
Inventor: FAKTOR MARC MARIAN
IPC: C01F7/021
Filed: 1967-02-03
Abstract: 1,203,441. Treating surfaces of alumina crystals. POST OFFICE. 2 Feb., 1968 [3 Feb., 1967], No. 5347/67. Heading CIA. A depth of the surface of a crystalline aluminium oxide member is removed by contact with molten vanadium pentoxide. The crystalline member may first be polished, and then at least one surface is contacted with molten V 2 O 5 , preferably at a temperature of 800- 1000 C., for from 15 minutes to 2 hours. The crystal is preferably kept stationary. The contacting with molten V 2 O 5  may be carried out in a plurality of stages. When sufficient depth has been removed to give a uniform surface, any residual V 2 O 5  is removed by immersion in hot, concentrated HCl, and the surface then washed in distilled water and alcohol, and dried in air. This treatment gives a smooth polished surface free from damage suitable, e.g. for deposition of thin Si films on to the Al 2 O 3  member. The Al 2 O 3  member may be of α-corundum or in a form which contains small quantities of metal oxide, as do ruby and sapphire. A pale violet film may appear on some surfaces, after immersion in the melt, which is resistant to chemical attack, although some changes occur on treatment with cone. HCl, HNO 3  or catechol in hydrazine hydrate. The films disappear after prolonged heating in air at 1200 C.

Abstract: 1,255,956. Regulating. COVRAD Ltd. Jan.29, 1969 [Feb.2, 1968], No.5403/68. Heading F1B. Means for regulating the temperature of air passing from an air compressor to an internalcombustion engine includes a first duct 10 for conveying the air from the compressor to a heat exchange 11 in which the temperature of the air is to be changed, a second duct 12 for conveying the air from the heat exchanger to the engine, a by-pass duct 13 for conveying air from the first duct to the second duct without passing through the heat exchanger, temperature sensing means arranged in the second duct at a position between the engine and the junction of the by-pass duct with the second duct and valve means 18 operable for controlling the rate of flow of air along the by-pass duct. The temperature sensing means is arranged to supply a signal for operating the valve means according to the temperature of the air in the duct passing the temperature sensing means, for the valve means to increase the flow of air along the by-pass duct as the temperature of the air passing the temperature sensing means approaches a predetermined value, whereby the air passing through the by-pass duct will mix with the air passing from the heat exchanger in such proportions that the temperature of the mixture of air conveyed to the engine will be inhibited from passing beyond the predetermined value. The heat exchanger may be arranged to cool the air passing therethrough but in a modification the heat exchanger is used to heat the supply of air from the compressor to the engine.

Abstract: 557,218. Artificial filaments, films, &c. BRITISH CELLOPHANE, Ltd. May 6, 1942, No. 6078. Convention date, May 6, 1941. [Class 2 (ii)] Regenerated cellulose filaments, ribbons, tubes, films or the like are obtained by extruding viscose into an acid coagulating bath in the presence of a small proportion of a polyalkylene oxide or polyalkylene glycol having a molecular weight of at least 400. Formation of deposits tending to clog the extrusion orifices is thus prevented or retarded. The polyalkylene oxide may be incorporated in the viscose, or in the coagulating bath, or in both. Preferably the polyalkylene oxide has a molecular weight not greater than 5,000. It may be obtained by heating the monomeric oxide in presence of an alkaline catalyst. A polyalkylene oxide which is soluble in water and benzene may be used. It may be obtained from ethylene oxide, propylene oxide, butylene oxide, cyclohexene oxide, or styrene oxide. The coagulating bath may contain sulphuric acid, sodium sulphate, zinc sulphate, and glucose. When the polyalkylene oxide is added to the viscose, the filaments and films are cleaner and show reduced lustre and increased water-sensitivity. When it is added to the coagulating bath the products show a more uniform cross-section but do not show increased water-sensitivity. The molecular weight of the polyalkylene oxide is calculated from the hydroxyl number.
