Title: Improvements in and relating to dough moulding machines
IPC: A21C3/00
Filed: 1929-06-12
Abstract: 329,198. Embrey, L. June 12, 1929. Rolling machines. - In a doughmoulding machine of the type comprising a rotating drum which cooperates with a stationary fence, the drum is composed of a series of discs which are obliquely mounted in relation to the geometrical axis of the drum and are rotated about their own geometrical axes. As shown, the oblique annular discs 1 which form the drum are held in position by grooved or stepped bars or rollers 2. The discs are rotated by frictional driving-bars 5 which are pivoted at 6 to forks 7 on spindles 12, 19 rotated by bevel gearing driven by pulleys 17, 18; the bars 5 thus revolving parallel to one another and in contact with the inner edges of the discs. The fence 27 is preferably made in sections each separately adjustable about the pivot 28 by adjusting-screws 29. A scraper 32 contacts with the discs. The drum and the fence form a wedge-shaped pocket into which the dough is carried. The discs form a grooved drum, the grooves being deepest at A and gradually decreasing until the point B is reached. The discs may have bevelled edges. According to the Provisional Specification, the oblique discs are bevelled and are mounted looselv on a central shaft. Thev are rotated by bevelled rollers which engage the discs at the point where the grooves are of maximum depth. Alternatively, the central shaft is driven through a change-speed gear and carries a spider which engages projections on the first disc. The discs are pressed together by a helical spring and the shaft has an oblique plate or thrust block which retains the discs at the required angle. A ball thrust bearing may be used.

Abstract: 146,335. Dubief, G. L. Oct. 13, 1917, [Convention date]. Fabrics composed of threads united by adhesives.-Relates to a machine for making continuous strips such as ribbons by sizing threads or filaments. The threads 1, Fig. 2, are fed from bobbins grouped on a rack in sections corresponding to the number of strips to be produced, being separated by combs 2 and assembled side by side at 1<a> on a width equal to that of the strip. The strips of threads are then guided by rolls 4, 4<a>, Figs. 1 and 2, through a paste-containing vat 3<a> having a submerged roll 5 and a pair of pressing-rolls 6, 7, the vat 3a being surrounded by a water bath 3 to maintain the paste at a suitable temperature. The rolls 4, 4<a>, 5, 6, 7 have circumferential notches corresponding to the width of the ribbons. The strips are next dried on both sides by being passed between pairs of rolls 9 heated internally by gas tubes and arranged around, and driven by, a toothed wheel 11. The sized ribbons then pass to a winding-mechanism 14 having a rotary and a to-and-fro movement for winding them on bobbins ready for sale. The machine has a shaft 15 provided with fast and loose pul. leys 16, 17 and driving the pressing rolls directly and the wheel 11 through gears 18, 19, 20, 21.

Abstract: 911,856. Adjusting steering columns. FORD MOTOR CO. Ltd. May 19, 1961 [May 27, 1960], No. 18293/61. Class 79(5). The steering column of a vehicle, especially a sports car, is pivoted by brackets 25, 26 to the vehicle bulkhead, the steering shaft. equipped with a steering wheel 11 and conventional steering box 29, being provided with a universal joint 28. The arrangement enables the steering wheel to be moved to one side to enable the driver to enter the vehicle. Along the length of the column, a bracket 43 is affixed by a strap 46 and is bolted to a hanger 32 having a nylon bearing piece 45 which slides between the arcuate flanges 31, 34 of a support member 33 secured to the bulkhead by a U bracket 37, there being a stop member 39 at one end and a centring spring-loaded pawl 54 (Fig. 5) at the other. The pawl 54 engages within a slot in the hanger member 32 and bearing piece 45. A solenoid 68 controls the position of a locking pin 69 and is in a circuit, Fig. 6, which includes the vehicle ignition switch 75, a switch 72 at the outboard limit of travel of the hanger member 32 and a switch 78 operated by the vehicle transmission which is of the automatic type. The arrangement is such that the solenoid is withdrawn to enable movement of the column when the transmission is in the "park" position whether the engine is running or not and if the column is not centred, the engine is cut out when the transmission lever is moved out of the "park" position. In a modification, Fig. 8, for use with a gear lever disposed on the steering column, a mechanical locking device is employed, comprising an arcuate member 94 fixed to the gearshift shaft by a bracket 85 and which extends through slots 92 and 91 in a flanged bracket 88 secured to the steering column and the arcuate hanger track 87, respectively, only in the normal postion of the column. The member 94 is clear of the guide track in the "park" position but remains through the slots in the engaged positions of the gears.

Homogeneous ferromagnetic bodies are made by adding a deflocculant and water to a powder consisting of a mixture of oxides, of which at least one is an oxide of a ferromagnetic metal, to produce slip, pouring the slip into a waterabsorbing mould to produce a cast, and then drying and sintering the cast, the constituents of the mixed oxide powder being so chosen that the resultant sintered body is ferromagnetic. Specified deflocculants are sodium silicate, ammonium alginate, pyridine, polyvinylamine, piperidine, tetramethyl-ammonium hydroxide, ethylamine, propylamine, butylamine, amylamine and triethylamine. A protective colloid may be added to the slip before casting. In a preferred embodiment, the proportion of powder particles having diameters less than 1/10 of the largest particles (about 20 microns) exceeds 5% by weight. Preferably the true specific gravity of the powder is more than 3, and the solids concentration of the slip is more than 50%. In examples: (1, 2) Mixtures of Fe 2 O 3 , ZnO and CuO are presintered, ground and added in varying proportions to ground mixtures of the same oxides having different particle sizes. The combined mixtures are slip cast and sintered at 1000‹ C.

Abstract: 906,657. Securing end-windings. GENERAL ELECTRIC CO. May 25, 1960 [May 26, 1959], No. 18524/60. Class 35. In a dynamo-electric machine, the end windings are rigidly anchored together by resilient spacers 1 interposed between adjacent conductor bars and fixed to one of them. The spacer 1 comprises a block 2, preferably laminated and impregnated with a heat resistant resin, carrying a spring member 3 which may be of metal but is preferably of an insulating material. In one embodiment the spring comprises an assemblage of resin impregnated glass fibre cloth which is either arcuate or corrugated. The dimensions of the spacers and configuration of the spring is largely determined by irregularities in the winding. The spring is secured to the block by layers of uncured resin impregnated glass fabric 4 which is in turn covered by a wrapping of lubricating material (examples of which are given) to facilitate press fitting the blocks into position. A tape 8, e.g. of glass fibre, is secured between the spring and the block and on insertion between adjacent conductor bars is cemented to one bar 8. When the winding assembly is completed (Fig. 4, not shown), it is heated to cure the resin in the tape 4.

Title: Method for removing water from liquid hydrocarbon compositions
IPC: C10G29/20
Filed: 1955-06-27
Abstract: Water is removed from a water-containing liquid hydrocarbon composition by maintaining the composition in contact with urea at an elevated temperature, until evolution of ammonia and carbon dioxide, formed from the reaction of the urea and water, ceases. The elevated temperature may be 150-212 DEG  F.  From 1.2-2 mols. of urea may be used for each mol. of water in the composition. Elevated or reduced pressures may be used to treat hydrocarbons not liquid under atmospheric conditions.  Unreacted urea may be removed from the treated compositions by filtration.  The process may be used to dehydrate transformer oils, gasoline, kerosene, Diesel fuels, fuel oils, lubricating oils and flushing oils, and to break water-oil emulsions.  In the examples, the treatment of white oil containing water, and crude oil emulsions containing salt water or water and caustic alkali is described.
