Title: Improvements in universal joints in particular for automobile vehicle transmissions
IPC: F16D3/18
Filed: 1958-11-06
Abstract: 848,178. Universal joints. ANCIENS ETABLISSEMENTS PANHARD & LEVASSOR, S.A., DES. Nov. 6, 1958 [Nov. 27, 1957], No. 35717/58. Class 80 (2). A gear type universal joint for front wheel drive motor vehicles shown in Fig. 4 as a double joint permitting 45 degrees angularity with constant velocity ratio, comprises a nylon or other plastic sleeve 8 having internal teeth which engage teeth 6, 7 on hubs connected one to a coupled shaft, the other to an intermediate member 11. In the double joint shown the hubs 5 are centred on the respective shafts 2, 13 by spherical joints 4, whilst the shafts themselves are centred by a sliding spherical joint 12. In the single joint, Fig. 1 (not shown), which permits 20 to 25 degrees angularity, the hubs are directly secured to the coupled shafts which are centred by a single spherical joint 4. The gear teeth 6 ... 8 which may be shaped, Fig. 3 (not shown), to make surface contact, allow a slight distortion of the sleeve 8 during high angular deflections. Axial movement of the sleeve is limited by end flanges on the sleeve 8 or on a surrounding casing 15 which does not interfere with radial movement of the sleeve. Radial expansion of the sleeve may be prevented by an inner spring sleeve 10. A flexible bellows 19 connect the casings 15.

Abstract: 448,707. Discharge lamps. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and LUCAS, G. S. C., 75, Eastlands Road, Rugby. Dec. 12, 1934, No. 35722. [Class 39 (i)] A gaseous arc discharge lamp, particularly a high-pressure vapour lamp, has an elongated tubular envelope, provided with current leads from contacts at or near one end of the envelope to electrodes situated at opposite ends of the envelope, the lead to the electrode remote from the contacts comprising a pair of conducting wires electrically in parallel and being so located that the resultant magnetic field at the axis of the arc due to current flowing in the two wires is zero. Disturbing magnetic effects on the arc due to the leads are thus avoided. In the form shown, the leads a, b are parallel to, equidistant from and coplanar with the axis of the arc and are contained within an outer envelope bearing a contact cap. Specifications 429,750, 429,872, and 435,310 are referred to.

The bobbin-carrier 13, supported and guided by pairs of angularlydisposed rollers 14, 15, is driven by gears 17 two at least of which always engage a toothed part 16 on the carrier. The gears are fixed to vertical shafts 18 carrying gears 20 engaging a toothed ring 21 and furnished with belt pulleys 22, all of which are driven by one belt from a shaft furnished with an electromotor. The carrier 13 has one or more rotatable pins 25 receiving conical cross-wound or bottle-shaped bobbins with connected threads to ensure continuous supply, the weft passing through porcelain eves 28. One or more looms mav be omitted, or warp threads may be omitted locally to form warpless strips along which the fabric may be cut. A jacquard may be used and various fabrics such as plain, twill, satin and damask may be woven in the various looms. In the Specification as open to inspection under Sect. 91, it is stated that the reed may be adjustable in width, that the weft may be controlled by jacquard mechanisms, that one or more of the bobbins or the yarns thereof may be replaced automatically.

Abstract: 1,130,907. Knitting-machines. LUWA A.G. 8 Aug., 1967 [10 Aug., 1966], No. 36399/67. Heading D1C. A pneumatic cleaning arrangement for a circular machine comprises a blower having an impeller 31 driven by an electric motor 29 and positioned above the machine cylinder. The blower is housed in a casing 22 provided with outlets connected to ducting 23, 43 conveying air from the blower to nozzles or other openings which direct the air towards various parts of the machine such as the yarn guides, tensioners, stop motions and yarn feeding devices. The whole casing and the ducting are mounted on the bobbin support and are caused to be rotated so that the jets of air directed from the ducting impinge in turn on the various components and cause the dust or lint which has settled thereon to be dispersed. The blower casing also has an inlet 32 covered by a filter element which as the casing is rotated draws in the dispersed dust and traps it. A suction head 37 stationarily mounted by the side of the casing removes the dust from the filter element on each revolution of the casing. The blower may be mounted to rotate with the casing or remain stationary within it.

Abstract: 761,220. Gas manufacture. FARRER, J. O. (Du Pont De Nemours & Co., E.I.). Dec. 20, 1954, No. 36838/54. Classes 55 (1) and 55 (2). Carbon monoxide-hydrogen gas mixtures are obtained for synthesis from a suspension of pulverized coal in superheated steam by mixing the suspension with oxygen of at least 90 per cent purity and passing the mixture at a temperature such that the coal is under incipient distillation into a combustion zone at a velocity preventing flash-back, partial combustion being effected at 1200-1700‹ C. Coal crushed in a hammer mill 3 is fed through a weighing hopper 5 and screw-feed metering means 6 into a steam pulverizer 8 in which it is comminuted for transport as a fluid stream to high velocity jet burners 10, 10a, arranged at the top of a gas generator 12 for axial and tangential direction respectively. Oxygen is supplied to the burners from a blower 11., Gaseous products flow through a water spray 22, a wash box 14 and cooler 16 to a holder, and molten slag drops into a quench tank 18 through a tapping hole 17 kept open by withdrawing some gas therethrough for eventual return to the main stream; this may be utilized for superheating the steam supplied to the pulverizer. To start up natural gas &c. introduced through an inlet 27 is burnt until a uniform temperature of 1000-1200‹ C. is reached, after which an increasing supply of coal-steam suspension is gradually admitted. The burners incorporate a preferably water-jacketed mixing chamber of a length at least 25 times its breadth to set up a high degree of turbulence. Steam or nitrogen may be introduced as at inlet 26. Or air may be supplied through a blower 25. An up-flow or side-flow of the reactants may be substituted for the down-flow arrangement. In one of a large number of examples the product gas is made up of C043.7, H 2  33.6, CO 2  19.6, N 2  2.5, CH 4  0.4, illuminants 0.2 per cent by volume.

[Also in Group XXXI] A vehicle speedometer comprises a narrow guide 21 fixedly mountable upon a windscreen 20 for guiding a rectilinearly movable indicator mark driven in accordance with speed by a drum 23 invisibly mounted in the frame 22 of the windscreen 20. The drum 23 is driven through a flexible shaft 25 by the vehicle if desired in parallel or serial connection with a normal tachometer. The drum 23 drives an endless band 24 guided at the top over a roller 26 mounted in the guide 21 which may be extended at the top so that the roller 26 may be hidden by the windscreen frame. The guide 21 may be a slotted tubular frame, Fig. 3, the two edges 28 of the slot 29 forming the sides of an indicator window through which the band 24 is viewed. The guide 21 may be a strip with a flange overlapping only one edge of the band 24. A scale may be marked on one or both edges, which may be stepped to indicate through a wider window when particular values are exceeded, Fig. 4. The indicator mark may be a conspicuous horizontal line 30 separating a neutral field of the band from an indicating field 32 contrasting with the neutral field which may be transparent or may match the scale background colour. The indicating field 32 may have longitudinal stripes of, say, green, orange and red of widths corresponding with the steps, Fig. 5 (not shown). With suitable guide rollers the two flights 24<SP>1</SP>, 24<SP>11</SP> of the band 24, may appear side-by-side, one flight carrying the indicator mark and the other the scale. The band may be transparent and the mark and scale coloured or non-transparent. The two flights of a transparent band may lie one directly in front of the other, the indicating field of the front flight progressively covering the scale on the other as the speed increases, Fig. 8 (not shown). In a modification, Fig. 9, the guide 21 is replaced by a transparent support 37, fastened to the windscreen, and carrying a tube 38 of narrow bore whose cross-section is circular at c, rectangular at b and a, as shown in Fig. 10, but is of constant area. A coloured liquid is pressed by a piston of a pressure cylinder from below into the tube 38, the piston being moved in accordance with speed. Reference has been directed by the Comptroller to Specifications 832,375 and 844,575.
