Abstract: 961,608. Disposition of brakes. TRACTOR RESEARCH Ltd. Oct. 8, 1962 [Nov. 28, 1961], No. 42551/61. Heading B7H. [Also in Division F2] In a motor vehicle, e.g. a tractor, having rear wheels 1, 2 rotatable with stub shafts 3, 4 which are driven through reduction gearings 5, 6 from half shafts 7, 8 extending from a differential gearing 9, each wheel encompasses the stub shaft and a brake assembly, BA, is carried by each half shaft and is located within the wheel. The stub shaft 3, Fig. 2, is rotatable in bearings 11, 12 and is connected to or integral with a flange 16 carrying the wheel. The half shaft 7 rotates in bearings 13, 14 and the brake assembly comprises friction plates 20 splined at 21 to the half shaft and a pair of rings 23 rotatable by toggle links operated by a link 24, the rings 23 having cam surfaces and enclosing a number, e.g. three, of equi-spaced balls whereby rotation of the rings forces the friction plates against a thrust plate 22 and against a cover plate 18 fitted to the axle casing 15.

Abstract: 935,974. Separating laundry articles. McGRAW-EDISON CO. Dec. 18, 1959 [Jan. 28, 1959], No. 43197/59. Class 117. [Also in Groups XIX and XXX] In an apparatus for folding laundry articles as they pass a folding zone having automatic control means for the selection of articles for folding and the rejection of other articles the articles are advanced in a travel path past the folding zone by conveyers, a by-pass member when in an operating position guiding the article through the folding zone and when in inoperative position causing the articles to by-pass the folding zone, the conveyers including a pair of lanes lying side-by-side and each lane being arranged to carry an article not exceeding in width the width of the lane, and both lanes being adapted to co-operate in carrying an article overlapping each lane, sensing means being provided between the two lanes on the travel path upstream from the by-pass member and adapted to be intercepted by the leading portion of any article overlying a portion of each lane, and motors, responsive to the interception of the sensing means, move the by-pass member to its operative position, the sensing means being disposed adjacent to the by-pass member so that the control of the normally spaced articles following each other in immediate sequence is effected without mutual interference. In the arrangement shown laundry articles are conveyed towards by-pass members 10L, 10R by belts 12 and from the by-pass members by belts 13. The conveyer comprises two lanes, one lane leading to and from the by-pass member 10L and the other to and from the by-pass member 10R. Each lane is divided into two courses A, B and C, D respectively. If an article of laundry overlaps two lanes a sensing means CF1, comprising a spring-loaded lever 23c connected to an adjustable actuating screw 23b, is operated to cause the by-pass members 10L, 10R to be pivoted to the open position to guide the articles on to conveyer 14 to be fed to a folding device 86. The by-pass members 10L, 10R are held in the open position until laundry articles pass an article responsive means CF2. The lanes are divided into two courses A, B and C, D respectively and if a laundry article overlaps courses A, B or C, D a between course sensing means FL or FR is operated to open the by-pass member 10L or 10R. If a laundry article passes along course A, B, C or D individual course sensing means S1 S2, S3 or S4 are operated to move the by-pass member 10L or 10R to the by-pass position if such member is in the open position. Gang switches are provided to allow either or both lanes to be set for folding articles if desired. The articles on leaving the conveyer 13 are stacked or draped over a fixed bar 90 by pivoted plate devices 88 reciprocated by an air motor 89.

As shown, hot primary coolant from a nuclear reactor passes through inlets 14, 15 of the heat exchanger and passes through tube bundle 22 to outlets 26, 25. The riser chamber 33 is provided with a series of apertures 34 to permit flow of feedwater from inlet nozzles 36 into downcomer 35 into the riser chamber 34 which may include an economizer. A superheater shroud 47 surrounds the upper portion of tube bundle 22 and superheated steam is discharged from an outlet 53 in the heat exchanger 10. As the maximum acceptable temperature difference is approached, the valve 55 in the auxiliary feed-water conduit 56 is opened in order to discharge some of the fluid directly into the riser chamber 33 to prevent the cold fluid from directly contacting the tube sheet, thereby avoiding the risk of distortion of the latter. While the valve 55 is being opened, the valve 40 in the main feed-water inlet 37 is being closed. Specification 1,292,236 is referred to.

[Also in Division F1] A compressor blade is made by securing boron fibres 12 in parallel relationship to an aluminium alloy backing sheet 14, cutting the sheet into shaped plies 18 which vary in length and width, stacking the plies one above the other and then compacting the assembly in a mould to form the blade shape. The fibres 12 may have a tungsten core and be coated with silicon carbide, the fibres being secured to sheet 14 by a coating 16 of aluminium alloy applied by plasma spraying. The plies 18 are stacked on both sides of a central aluminium core 24, the smallest ply 20 being innermost and the largest 22 outermost, and are tack welded in position prior to moulding. In the latter operation the stacked plies 18 are placed between the two parts of a die 32 disposed between pressure plates 34, 36 slidable in a housing 38 heated by an induction coil 40. The die 32 is heated in a high vacuum to between about 549‹ and 566‹ C., i.e. about 25‹ C. below the melting point of the aluminium alloy and then a pressure of about 246 kg/cm.<SP>2</SP> is applied causing the alloy to flow and fill the voids between the fibres 12. Stops 44 limit the movement of the plates 34, 36 towards each other. The temperature and pressure are maintained for about 1¢ hours after which the die 32 and blade are allowed to cool while the pressure is maintained. The blade is removed from the die and any excess alloy 42 trimmed-off. If not added prior to moulding, a pair of profiled root elements (30, Figs. 8, 9, not shown) are then secured to the blade.

IPC: C10L1/12
Filed: 1961-12-15
Abstract: A fuel oil composition comprises a hydrocarbon fuel oil (e.g residual oil) containing vanadium compounds and a corrosion inhibitor, said inhibitor comprising a diluent oil, an oil-soluble dispersing agent, and discrete particles of magnesium oxide, hydroxide and/or carbonate uniformly and stably dispersed in the diluent oil, the amount of said inhibitor being sufficient to give a molar Mg-V ratio of at least 2 : 1, the diameters of said discrete particles not exceeding 0.25 microns, and the magnesium content of the inhibitor being from 4-10 wt. per cent. The inhibitor is formed by condensing the oil-insoluble magnesium compound from an alkanol-soluble magnesium - alkoxide - carbon dioxide complex dispersed in the diluent oil together with a dispersing agent, by heating the mixture to remove the alkanol (which has less than 6 carbon atoms) and decompose the complex, for example as described and claimed in Specification 836,855. The diluent oil may be a mineral oil, vegetable or animal oil, or propylene polymer, polyoxyalkylenes and esters thereof, dicarboxylic acid esters, or esters of acids of phosphorus, and may be diluted with a solvent, e.g. petroleum naphtha or a hydrocarbon. Many diluent oils and additional solvents are specified. Dispersing agents are discussed under the headings sulphonates, phenolic compounds, organic phosphorus compounds, phosphorus sulphide treated olefins, metal soaps of carboxylic acids and nonionic and cationic oil-soluble surface-active agents. Many examples of substituted and unsubstituted compounds falling under these headings are given.
