Title: A vehicle steering wheel having an adjustable rim
IPC: B62D1/08
Filed: 1936-10-01
Abstract: 468,489. Hand wheels. DOVER, Ltd., and DOVER, J. A. Oct. 1, 1936, No 26664. [Class 80 (iv)] A vehicle steering-wheel has a boss adapted to be mounted rigidly on the end of a steering column and a rim which is adjustable axially with respect to the boss, the rim being connected to the boss by two or more pivoted telescopic spokes. The boss 11 is connected to the rim 12 by three or more telescopic spokes, each comprising a rod 14 hinged to lugs 17 on the boss and entering a sleeve 15 hinged to the rim 12. A return spring 34 may be inserted between the rod 14 and a plug 36. The hinge portion of each rod 14 is formed on its underside with teeth forming a portion of a pinion 18 adapted to be engaged by teeth on a ring 19. This ring is adapted to be pressed against the pinions 18, to lock them, by a screwed collar 20 threaded on the boss and provided with spring plungers 23 engaging a groove in ring 19 to ensure smooth operation. To adjust the rim 12, the collar 20 is unscrewed to separate the teeth when the rim 12 may be adjusted by pushing or pulling, the spokes meanwhile telescoping and pivoting. After adjustment, the collar is screwed up and the pinions 18 locked. In Fig. 4, the teeth 18 on each of the rods 14 engage a rack-like surface on a block 25 which is movable in an eccentric slot in a plate 27 rotatable by a lug 28. Rotation of this plate causes the blocks to move radially and rotate the spokes about their pivots. After adjustment, locking is effected by a screwed ring 20. In a further modification, the teeth 18 are replaced by a lug engaging the eccentric arcuate slot in the plate 27, the locking being effected by cam-headed levers bearing against a disc washer under the plate. The locking devices described above may be replaced by locks on the telescopic portions of the spokes, e.g. leaf-spring and pin. The spokes may be made flexible by providing clearance between each rod 14 and sleeve 15 and inserting therein a helical spring or a rubber or fluid cushion.

Abstract: 241,945. Dubilier Condenser Co. (1925), Ltd., (Assignees of Houck, H. W.). Oct. 24, 1924, [Convention date]. Thermionic valve circuits. - Comprises structural arrangements of apparatus for supplying valve circuits from house mains. As shown in Figs. 1 and 3, the unit comprises condensers 4, 5, C<a>, Cb, c, and three coils 14, 15, 25 and is covered by a cap 1 extending over the top and opposite ends of the coils. A block 2 is placed beneath the coil 25 to make the sides of the stack rectangular and bands 3, 3a encircle the stack to render it compact. The condensers 4, 5 and C<a>, Cb are respectively enclosed in casings 6 open at the ends and with central partitions 7. Conductors 8, 9 lead respectively to condensers 4, 5 which have terminal plates 10, 11 while the remaining condensers have similar plates. The coils 14, 15 are on opposite limbs of the same closed core 16 and the coil 25 is arranged on a core 16 in such a, way that the adjacent limbs of the two cores have like polarity, as shown in Fig. 1, so that they are not inductively related. Fig. 6 shows a scheme of connection of the appliances, their application being in smoothing out ripples from direct current supply when the latter is used to supply the anodes of wireless receiving valves. The receiver is connected to the terminals T<1> - - T<3>, and an impedance r may shunt the coil 25 to improve the filtering. L-shaped laminations L are used in the cores 16 which are secured by clips 30 having upturned sides 31 and overturned ends 32. In the modification shown in Figs. 7, 8, 11 and 12, the stack comprises coils 37, 46, 49, 52 and condensers C<1> - - C<3>, 58, with a cap 2a similar to that 1 covering the sides and ends of the coils 37, 46 and a frame 1<a> comprising a base 33<a> and sides 34<a> serving to make the stack rectangular. Fig. 12 shows the diagram of connections, the terminals 35, 36 being connected to a source of rectified alternating current converted into a pulsating unidirectional one, and the terminals 61 - - 63 to the input terminals of a radio receiving set. The coils 49, 52 are wound so that the fluxes in adjacent limbs of the core are in the same direction and one coil will have no inductive effect on the other.

Abstract: 1,223,844. Rotary pumps. ROLLS ROYCE Ltd. and GENERAL MOTORS CORP. June 10, 1968 [June 9, 1967], No.26842/67. Heading F1F. In an internally-meshing gear pump comprising a housing 12, Figs.1, 2 within which is mounted an externally-lobed driving gear element 11 and an internally-lobed driven ring gear element 13 having one more lobe, all but two adjacent external lobes 20 and two adjacent internal lobes 14 are cut away to be of less axial extent than the full axial length of the gear elements so that during pump operation pumping occurs only in the spaces sealed by the intermesh of the full length lobes. Thus in the embodiment shown, with six external lobes, and seven internal lobes with six pumping spaces, pumping will occur in one pumping space every seven cycles so that pump output is only 1/42 of what it would have been if the lobes had not been cut away. The pump includes a single kidneyshaped inlet port 26 and two output ports 29, 30 fitted with non-return valves 34, 35 and between the ports 29, 30 in the direction of rotation of the gear elements, a by-pass port 32 connected by a passage 33 with the inlet port 26. Thus small accurately metered quantities can be passed through a pump having practical dimensions.

Title: Improvements in the manufacture and production of polymerisation products from indene, or styrene, vinyl esters and like mono-vinyl compounds
IPC: C08F2/02
Filed: 1931-09-29
Abstract: Polymerization products of indene, styrene, vinyl esters and like monovinyl compounds after the reaction is complete but still in the hot state are pressed out of the reaction space by means of a difference in pressure such as increased pressure or a vacuum to give products that may readily be pulverized, dissolved, comminuted or rolled out.  By means of suitably shaped nozzles rods or threads which may be collected on spools may be obtained or the product may be directly injected into moulds.  Catalysts, softening agents, fillers, and the like may be added during the polymerization which may take place continuously.  In examples (1) styrene is polymerized in a pressure-tight vessel and the product is pressed out under a pressure of nitrogen giving a thread which may be comminuted; the hot product may be directly pressed into a closed mould or the disintegrated cold material may be fed into an injection moulding machine.  Covers for electric switches or other insulating articles for electric or wireless apparatus, vanity boxes, powder boxes, knobs, handles, buttons, or transparent or coloured artificial jewellery may be made.  (2) A mixture of monomeric styrene which still contains ethyl benzene and tricresyl phosphate is forced through a heated tube coil and the product is taken off from a nozzle.

Title: Process for removing methanol from methanol-containing mixtures
IPC: C07F5/04
Filed: 1962-07-16
Abstract: Methanol is removed from a methanol-containing mixture by treating the mixture with formaldehyde in the presence of an acetalisation catalyst to convert the methanol to methylal and removing this from the mixture by distillation as soon as it is formed.  The formaldehyde may be used in the form of a polymer or as formalin solution.  Suitable acetalisation catalysts are, for example, hydrochloric or sulphuric acid, calcium chloride, p-toluene sulphonic acid, cation exchangers, aluminium chloride, zinc chloride, piperidine hydrochloride, sodium bisulphate, ferric chloride, orthosilicic acid esters, titanic acid esters and dimethyl sulphite. If desired the catalyst may be neutralised after the acetalisation is complete by treatment with sodium carbonate, sodium acetate or an organic base. In the examples methanol is removed from a mixture of methanol and (a) methyl acetate, (b) trimethyl borate, (c) acetone, and (d) methyl acrylate. It is stated that the process may be used for the removal of methanol from mixtures of methanol and methyl esters of acrylic or a -alkyl acrylic acids.
