Title: Vehicle turning radius gauge
IPC: G01B5/255
Filed: 1964-01-31
Abstract: 996, 936. Alignment gauges. DURA CORPORATION. Jan. 31, 1964 [Feb. 8, 1963], No. 4180/64. Heading G1X. Apparatus for checking the aligment of vehicle wheels comprises a stand 18, a wheel supporting member 22 pivotally mounted on the stand 18 by a pin 24 for rotation in either direction, stop means 50 which can be arranged to engage the member 22 against rotational movement in one direction, the stop means being automatically disengaged when the member 22 is biased to move in the other of the two directions. The member 22 carries a pointer 36 which moves over a scale or a turning radius indicia plate 34 carried by a retractable member 26 forming part of the stand 18. The pointer 36 is adjustable by means of screws 40, 42 to zero it on the scale. The member 22 also carries a shoulder stop 44 against which an adjustment screw 68 forming part of the stop means 50 may be made to abut in use, (Fig. 5). The screw 68 is carried on a bracket plate 52 pivoted on a screw 54 on the member 26. A leaf spring 62 normally urges the screw 68 clear of the stop 44. In use two of the apparatus shown in Fig. 2 are employed are to support each front wheel of a vehicle. With the vehicle properly aligned on the apparatus and with the pointer 36 zeroed on the turning radius scale, the vehicle wheels are turned e.g. to simulate a left turn through 20 degrees as indicated by the pointer and scale associated with the right hand front wheel of the vehicle. The screw 68 is moved so that it abuts the stop 44 and the screw is adjusted to maintain a reading of 20 degrees on the scale. The operator crosses to the left side of the vehicle and notes the reading on the turning radius scale which should correspond to 20 degrees with the Ackerman effect taken into account. The left wheel is then turned further into a left turn so that the screw 68 associated with the right hand side of the vehicle will be released and will disengage the stop by action of the spring 60 allowing the wheels to return totheir straight ahead position by castor action. The apparatus supporting the right hand vehicle wheel is now set to simulate a 20 degrees right hand turn using its adjustment screw 68 and the reading on the scale taken at the left hand front wheel completing the alignment check.

Title: Improvements in methods and apparatus for the manufacture of moulded bodies from mortars or concretes
IPC: B28B3/02
Filed: 1934-02-09
Abstract: 431,484. Piles. FREYSINNET, E., 28. Rue St. James, Neuilly-sur-Seine, France. Feb. 9, 1934, Nos. 4372 and 4373. Convention date, Feb. 9, 1933 and Jan. 22, 1934. [Class 68 (ii)] [See also Group V] Piles are moulded from damp concrete by filling a non-rotary mould with the concrete which is then subjected, in a first phase, to vibration accompanied by pressure applied to the upper portion of the concrete, which pressure coacts with the vibration to produce compactness but is not strong enough to prevent relative displacement of the elements of the concrete, after which the compact concrete is subjected, in a second phase to a substantially greater compression, preferably obtained by reducing the size of the mould. Piles may be manufactured in successive portions as shown in Fig. 16. The mould 82 is connected by an element 81 to a previously formed portion of the pile and an expansible mandrel, comprising a wooden core 51 surrounded by an elastic envelope 53 and wooden staves 55, is placed inside, the mandrel having an annular projection 84 at the top end to form a recess in the concrete. Reinforcements 85 are placed in the mould which is filled by means of a hopper 86, the material in which provides the light pressure. The mould is vibrated by rotating eccentric masses. The hopper is then removed, a closure plate 87 is applied, and the mandrel is expanded by fluid pressure. When the mould is removed the end element 81<a> is left in position. The method is particularly applicable to screwed piles.

Title: Improvements in and relating to bearings
IPC: F16C17/22
Filed: 1921-02-08
Abstract: 181,060. Parsons, Sir C. A., and Cook, S. S. Feb. 8, 1921. Self-adjusting bearings.-A number of compensating-elements are mounted in a common support, differential expansion of the elements and their support acting to allow them to come closer together as the temperature rises, and vice versa, in order to equalize the load and prevent seizing. In a cylindrical bearing, a brass bush b, Fig. 1, has formed in its outer periphery a number of circumferential grooves with tapered sides d, in which are arranged a series of segments e of steel or invar steel which are surrounded by a backing h. Should local heating occur, the bush b expands more than the segments e, and the latter sink deeper into the grooves. In a modification, the segments are replaced by conical plugs inserted in recesses in the bush, various forms of plugs being described. Fig. 6 shows the invention applied to a pivoted thrust pad, the brass pad k being provided on its rear face with a number of conical holes n containing steel plugs o which bear on a backing r provided with the pivot s. In place of conical plugs, screwed plugs u, Fig. 7, may be inserted in threaded holes in the pad k. in which case the plugs slacken with rise of temperature and sink further into the hole. Keys v are fitted to prevent the plugs turning, and the threads may be of the interrupted type. In order to obtain a greater compensating effect, the plugs may be threaded into an additional brass plate k<1>, Fig. 9, which rests against the backing r. This arrangement may also be applied to the case of conical plugs by making them double-conical. Fig. 11 shows the invention applied to the slippers z of a cross-head, conical plugs 3 being used. The invention may also be applied in the case of conical or curved bearing-surfaces. Instead of using metals having different coefficients of expansion, unequal heating may be relied on to provide the necessary differential expansion. Specification 172,119 is referred to.

Abstract: 788,609. Gas turbine plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Feb. 15, 1955 [Feb. 26, 1954], No. 4511/55. Class 110 (3). [Also in Group XXVII] A power plant comprises an internal combustion piston engine driving an air compressor comprising at least two stages, air from the higher pressure stage being supplied to the engine while air from a low-pressure stage is mixed with exhaust gases from the engine, the mixture of air and exhaust gases being used to drive a gas turbine. The amount of air used for mixing with the gases is greater than that passing to the engine. The internal-combustion piston engine 1 in Fig. 1 drives a two-stage centrifugal type air compressor 5 through a coupling 6. Air from the second compressor stage at pressure Pa passes to the induction manifold 8 and exhaust gases are discharged through the manifold 10 into a duct 9 where they are mixed with air discharged from the first compressor stage at pressure Pe, pressure Pa being greater than Pe. The mixture of gases and air passes to the turbine 11. In Fig. 6 is shown an assembly of engines a1, a2 ... each driving an air compressor. The mixture of exhaust gases and air from each engine is collected in a manifold 9a and after further heating in the combustion apparatus 40, the gases pass to the turbine 11. A suitable type of engine is shown in Fig. 3 comprising a piston 4 disposed in a cylinder having admission ports 17 and exhaust ports 16 controlled by a sleeve valve 18. The inlet ports are controlled by ports 20 in the sleeve and the exhaust ports by the top edge of the sleeve. The sleeve is given a combined reciprocating and rotary movement by means of a crank 21 on a shaft 23 which is driven by gearing from the main crankshaft. The support 25 of the shaft 23 may be rotated about the axis 28 by means of a servomotor piston 29 acting 'against the spring 30, thereby varying the areas of the admission and exhaust openings, as described in Specifications 742,303 and 742,360, [both in Group XXVII].

Patent GB-903053-A (GB)
Title: Process for the reaction of organic aluminium compounds with olefines
IPC: C07C1/32
Filed: 1959-02-10
Abstract: Organo aluminium compounds of formula X(n)[Y-AIR2]n in which X represents a monovalent or polyvalent hydrocarbon radical, n represents the valency of X, Y represents oxygen or sulphur and R represents a hydrocarbon radical containing no unsaturated carbon-carbon bonds on the carbon atoms bound to the aluminium atom are reacted with olefines in the presence of an aluminium compound in which the three valencies of the aluminium atom are bonded to carbon, or in the presence of a dialkyl aluminium hydride, an alkyl aluminium hydride or aluminium hydride as catalyst.  The grouping XY in the aluminium compound may be the residue of an alcohol, mercaptan, phenol, thiophenol, or a nuclear-substituted phenol, thiophenol, naphthol or thionaphthol in which the substitutent is an alkyl group. X and R may be the same or different and may be alphatic, alicyclic, aromatic, aromatic-hydroaromatic or aliphaticalicyclic radicals. Thus addition of olefines e.g. ethylene gives higher homologues of the starting compounds: this reaction takes place at pressures above 10 atmospheres and temperatures between 90 and 170 DEG C.  Above 170 DEG C. a displacement reaction occurs.  These two reactions can be combined, especially if one R is a radical higher than C2H5, first adding on olefine and then raising the temperature, in the presence of nickel to displace higher olefines from the compounds formed. Thus compounds of formula XYAl[C2H4)nR]2 can be synthesised from XYAlR2 and ethylene in the presence of an aluminiuhm compound in which all three valencies of the aluminium are bonded to carbon, and then on adding a small quantity of colloidal nickel, displacement occurs yielding XYAl(C2H5)2 and H2C= C(C2H4)n-1C2H5.  The catalyst may be inactivated by addition of carbon dioxide or a carbonyl compound, an alcohol, thioalcohol or carboxylic acid.  The products of the synthesis reaction may be converted into alcohols by oxidation. Specifications 742,642, 763,824, 770,707, 773,539 and 804,325 are referred to.
