Title: Improvements in vehicle suspensions
IPC: B60G11/14
Filed: 1933-11-13
Abstract: 413,931. Vehicle spring-suspensions. DUBONNET, A., 114, Boulevard Maurice Barres, Neuilly-sur-Seine, France. Nov. 13, 1933, No. 31580. Convention date, Nov. 14, 1932. [Class 108 (ii).] In road vehicles in order to prevent dipping of the front end of the chassis during braking the steering wheels are connected to a casing pivoted about a vertical axis on the chassis by means of at least one arm the movement of which is resisted by spring means housed in the casing and means are provided connecting the fixed or reaction part of the brakes to the casing to prevent rotation of the part. As shown the wheel is supported by a lever a the end of which is provided with a series of arms bearing against springs b in a casing c as described in Specification 344,788. In addition the plate f supporting the brake shoes is mounted in the brake drum so as to be rotatable therein and is restrained by a rod h connected thereto and to the casing c mounted on the chassis so that when the brakes are applied the force or couple tending to rotate the plate f is resisted by the rod h and transmitted as a reactive force to the chassis tending to counteract the dip or fall of the latter due to braking or deceleration. Fig. 4 shows the arrangement of rods h and levers a when the front and rear wheels are mounted to the rear and to the front of the casings c respectively. Instead of rods h similar restraining means mounted on the chassis such as guides may be used. In a modification the fixed or reaction plate of the brakes carries the stub axle and is connected to the casing &c. by two torque rods.

Title: Improvements in or relating to the conversion of heavy hydrocarbon oils into oils of lower boiling point by heat treatment in the presence of hydrogen
IPC: D01H7/56
Filed: 1931-11-16
Abstract: Carbonaceous residues obtained in the destructive hydrogenation of oils are treated with superheated steam at high temperatures with the formation of gases containing hydrogen and carbon dioxide which are used as the hydrogenating gases for the destructive hydrogenation reaction.  The latter comprises a multi-stage cyclic process under varying conditions of temperature and pressure, the vapours and gases from one stage being recycled to another stage.  The oil is treated in a series of reaction stills B<1>, B<2>, B<3>, provided with hydrogenation chambers A<1>, A<2>, A<3>, gas domes C<1>, C<2>, C<3>, and interposed desulphurizing chambers E<1>, E<2>, E<3>.  Vapours from the last still are passed to a dephlegmator hydrogenator D while the liquid residues are fed to a chamber F in which, after removal of heavy oils for recycling to the stills, the carbon-containing residues are decomposed by treatment with superheated steam.  The reflux from the dephlegmator D is divided and subjected to vapour phase hydrogenation, one part under super atmospheric pressure in a heater I, flash chamber J, desulphurizer E<4>, heating coil LL, cracking stills L<1>, L<2>, L<3>, cooling coil K, and dephlegmator M, and the other part under reduced pressure in a heater P, flash chamber Q, desulphurizer E<5>, heater R, cracking chambers S<1>, S<2>, S<3>, cooler SS, and dephlegmator T, the <PICT:0396065/III/1> <PICT:0396065/III/2> vapours from the dephlegmators D, M, T being condensed to give the final low boiling point product.  Each reaction zone comprises a still 1, Fig. 2, mounted on a firebox 2 and provided with vertical hollow cylinders 6, 4 forming the hydrogenation and gas chambers B<1>, C<1>.  Pipes 7 . . 10 admit charging oil, partially treated oil, hydrogenating gas, and superheated steam respectively into the cylinder 6 and the mixture is removed through a pipe 11 by a high speed spiral pump 14 and forced along a homogenizing tube 12 into the still 1.  The latter is provided with an agitator comprising an endless conveyer chain 18 fitted with scrapers 23 having gas-entrapping chambers 24.  The agitator may be replaced by a plurality of steam jets.  Hydrogenating gas formed in the reaction accumulates in the dome C<1> and is discharged through a pipe 5. Heavy oil and sludge are discharged through a spiral pump 32 to a pipe 35.  The hydrogenating chambers C<2>, C<3> of the stills B<2>, B<3> are provided with screens supporting catalysts.  The hydrogenating gas entering through the pipe 9 is produced in the chamber F in which sludge from the last chamber B<3> is treated with superheated steam at 1400 DEG  F. with the formation of gases consisting chiefly of carbon monoxide and hydrogen which are passed through screens charged with iron oxide and are then recycled to the stills and also to the heating coils I, P, where the reflux oils from the dephlegmator D are hydrogenated further in the vapour phase.

Title: Net-Like Structure.
IPC: B29D28/00
Filed: 1968-07-03
Abstract: 1,184,635. Net-like structures. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 3 July, 1968 [4 July, 1967], No. 31784/68. Headings B5A and B5B. Net-like structures are produced from heatshrinkable thermoplastic sheet material by exposing the sheet to infra-red radiation while it is close to or in contact with a pattern composed of areas of good infra-red absorption properties and interconnected areas of poor I.R. absorption properties, and heating the sheet to induce shrinkage while maintaining the position of the peripheral edge thereof. The sheet material preferably shrinks on heating by at least 10%. Preferably the starting material has been stretched biaxially. Examples of films used are those of calendered stretched and extruded stretched polyvinyl chloride, polypropylene, polythene linear polyester, vinyl chloride and vinylidene chloride copolymer, and biaxially stretched polystyrene. Suitable films have thicknesses in the range of 10 to 200 microns. In Fig. 1, for a continuous process film 2 from the roll of plastics material 1 is passed over roller 3 provided with a sleeve 4 of white plastics on which a pattern has been arranged. The infra-red heater 5 is situated just above roller 3. The film 2 then passes a series of rollers 6, 7, 8, 9 and 10 of which rollers 6, 7 and 8 are heated to a desired temperature, e.g. by steam or by electricity. The large contact surface of the rollers and the undulated path of the film provide a friction surface preventing shrinking of the entire film so that only local tear-shrinking takes place at the areas of mechanical weakening caused by the I.R. radiation. In another embodiment a pair of drive chains with clips is used for holding the edges of the film which is heated as it passes the chains. Various methods of obtaining the pattern are described.

Title: Improvements in engine-starters
IPC: F02N15/06
Filed: 1920-11-10
Abstract: 153,870. Eclipse Machine Co., (Assignees of McGrath, W. L.). Nov. 13, 1919, [Convention date]. Turning-gear.-In an electric or like starter comprising a driving-pinion 5 arranged for rotary and axial movement, the axial movement is effected by the depression of a plunger 24 by hand or foot, and if the pinion teeth clash with those of the engine fly-wheel, a rotary motion is imparted to the pinion or shaft upon release of the plunger, so that on a second operation of the plunger the position of the pinion relative to the engine member is altered. In the form shown, the pinion 5 and the shaft 2 of the starting-motor 1 have inter-engaging helical splines 4, and an extension 8 on the pinion has a head 9 with a cam-surface 10 engaged by rollers 14 on arms 13 depending from a slide 11. The slide is actuated from the plunger 24 through a bell-crank lever 18 having a pivoted finger 21, which engages the slide on the forward movement and is free on the return. The parts are normally held in the position shown by springs 27, 23. The depression of the plunger moves the pinion 5 wholly or partly into mesh with the fly-wheel, the movement being completed, in the latter case, by the rotation of the shaft 2. If the teeth clash, the plunger is released and the parts are returned by the springs 27, 23. If the rollers 14 are in engagement with the bottom of the cam-surface, the pinion 5 is held against rotation on the return movement and effects some rotation of the shaft 2, so that the parts are in a different position for the next engagement. If the rollers are not at the bottom of the cam, they effect some rotation of the pinion, with the same effect. The depression of the plunger may close a switch 30 supplying current to the starting-motor. In a modification, the splined part 4 is connected to the motor shaft 2 through a coiled driving-spring.

Title: Improvements relating to automatic gate-opening gear
IPC: E05F13/04
Filed: 1936-11-24
Abstract: 485,475. Door-operating apparatus ; fastenings. HASLAM, O. H. Nov. 24, 1936, No. 32212. [Classes 44 and 65 (i)] In automatic gate - operating apparatus of the kind in which a wheel of an approaching vehicle depresses a ramp or platform to open the gate through linkage or other connections, the vehicle holding the gate open by its weight until it has passed through, each ramp 8 has the end adjacent to the gate 3 pivotally supported at 11 and the other end connected to the gate-operating means and comprises members or teeth 21 projecting upwardly through a fixed grid or the like 22 which takes the weight of the vehicle when the ramp is depressed. The ramps are connected by a bridge-piece 4 extending under the gate and resting on the ramps at 24 to maintain the gate open during the passage of the vehicle ; the bridge-piece 4 may be constructed in the same way as the ramps, as shown, or may present a continuous surface and be depressed on to supports which take the weight of the vehicle. In the arrangement shown, a bracket 13 on the outer end of each ramp is supported by a three-armed crank 9 which is counterweighted to hold the ramp normally raised and is connected by a cable 16 to a wheel 25, this wheel being weighted to return it to its normal position after operation of the gate. A pin 30 on the wheel 25 engages a quadrant 31, which is freely pivoted on the axle of the wheel 25 and has a small counterweight 33 tending to move it anticlockwise, and a cable 32, adjustably attached to one end of the quadrant 31, runs round a quadrant guide 34 fixed to the gate 3 and is attached to a lever 35 pivoted to the quadrant 34. The lever 35 is connected by a link 44 and crank to a spring-returned latch-operating member, so that the first movement of the operating cables 16 releases the latch and the crank 35 then abuts against the quadrant 34 so that further movement opens the gate. The gate is closed by any weight or spring means when released, and is operable by hand independently of the mechanism. The latch may be dispensed with, the cable 32 then being attached to an arm on the gate or a lever which is pivoted on the gate-post to push against the gate or is otherwise connected to the gate.

Title: Neopentane separation of bituminous materials
IPC: C10G1/04
Filed: 1966-07-18
Abstract: A process for recovering oil from an oil-bearing bituminous material containing bituminous resins and oil comprises intimately contacting said bituminous material with liquid neopentane at a temperature within the range of 0 DEG  to 250 DEG  F., separating the resulting mixture into a first fraction comprising bituminous oil dissolved in neopentane and a second fraction comprising undissolved bituminous material including said resins, and recovering the oil from the first fraction.  The oil so obtained is free from asphaltenes, resins and waxes.  The insoluble portion may be separated by settling, centrifuging or filtration and may then be treated with another paraffinic solvent to extract resins.  Alternatively the bituminous material may first be extracted with n-pentane or iso-pentane to extract oil and resins, and the resins subsequently precipitated from the solution with neo-pentane which dissolves only the oil.

Title: Improvements in or relating to universal joint constructions
IPC: F16C11/06
Filed: 1937-11-23
Abstract: 485,844. Universal joints. POLLAK, J. E. (Thompson Products, Inc.) Nov. 23, 1937, No. 32263. [Class 65 (ii)] A universal joint, having a stud element 11 adapted for swivelling and tilting movement with respect to the housing 10 and means 26 for constantly urging the stud end 13 into closer bearing relation with the inner bearing wall, has the said wall arranged for bearing contact only over those localized areas within which the majority of the tilting movement takes place. The inner bearing wall of the housing 10 contacting with the segmental spherical bearing portion 12 of the stud 11, which moves largely in the vertical plane containing the axis of the tie rod 21 or a plane parallel thereto, has the portions 18, 19 which are subject to little or no wear cut away so as to allow the stud to reseat itself as the bearing surfaces 16, 17 wear away. The bearing surfaces 16, 17 may be frusto-conical in form and may be either integral with the housing 10 or part of a separate member forced into it. In another modification the bearing surfaces are of segmental spherical formation. In a further modification the bearing portion 12 of the stud 11 is circumscribed by a hemispherical seating member which co-operates with localized bearing surfaces in the housing 10. This arrangement allows free rotational movement of the stud 11. In order to lubricate the joint the closure plate 27 may have an opening into which a plug may be fitted, and cap member 23 may have holes allowing the lubricant to reach the bearing surfaces of the joint.
