[Class 80 (iv)] A steering-wheel is formed of pieces of pressmoulded non-metallic material mounted upon a metallic frame. Fig. 2 shows spokes 2 connected to the boss and metal rim 3, pressmoulded pieces 9, 11 being placed on the spokes 2 and rim 3. The pieces 11 may have projections and hollows at their engaging ends. The rim frame may be in two portions. The rim frame ends may be joined together by a conical-headed bolt to cause tension. Fig. 6 shows the press-moulded pieces 17, 22 forming the spokes and the portions of the rim between the spokes and being provided with sockets 19 to enable them to be connected by the frames 20 embedded in the masses 21. Fig. 8 shows the press-moulded pieces constituting a spoke 171 and the portion of the rim between two spokes. In a further construction the wheel is built up from T-shaped pieces forming a portion of the spoke and a portion of the rim extending on either side and other pieces to complete the spoke and rim. The Specification as open to inspection under Sect. 91 comprises also the following subjectmatter. The metallic frames of the spokes and the rim may consist of pressed sheet metal pieces of varying profile in which case each of the press-moulded pieces may be in halves and connected to each other by screws. The halves may be of the same shape or of different shapes 37, 38 as shown in Fig. 18 (Cancelled). The press-moulded pieces may be cup-shaped with curved ends to engage in the hollow ends so that they may adapt themselves to any radius of curvature. The press-moulded pieces may also be of oval cross-section mounted on similarly shaped frames, the major axis of the rim frame section being at an angle to the plane of the wheel. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,128,115. 1,2,3,4-Tetrachlorotetralin. KOPPERS CO. Inc. 25 July, 1967, No. 34094/67. Heading C2C. 1,2,3,4 - Tetrachlorotetralin, containing substantially more of the isomer which melts at 182‹ C., is prepared by contacting in an inert atmosphere a solution of naphthalene in an inert organic solvent, at a temperature in the range 20-60‹ C. with approximately two moles of gaseous chlorine per mole of naphthalene while exposing the solution to light. The 1,2,3,4- tetrachlorotetralin so obtained may be hydrolysed by refluxing with water to give 1,4-dihydroxy - 2,3 - dichlorotetralin, which is then heated with excess nitric acid at 70-100‹ C. to give 2 - chloro - 1,4 - naphthoquinone. The 2- chloro-1,4-naphthoquinone may then be treated with chlorine to give 2,3-dichloro-1,4-naphthoquinone. Suitable inert solvents for the naphthalene are, e.g., carbon tetrachloride, chlorobenzene, dichlorobenzene, nitrobenzene, trichloroethylene and perchloroethane.

The valve assembly comprises a tip sealing valve body 106 and a tip sealing valve pintle 114 with a spring 116 interposed between them and, in the non-discharge condition, fluid pressure and spring 9 cause the body 106 to compress the spring 116 against the pintle 114 so that valve tip 10 closes the passage 11 in atomiser assembly 2. In this non-discharge condition, shown in Fig. 5, there is a continuous circulation of fluid within the injector via passages in swirl plate 4 and distributor plate 5. On operation of a change-over valve (14) (Figs. 1-4, not shown) flow is reversed and most of the fluid supplied via duct 15 is discharged after the tip sealing valve has opened, shown in Fig. 6, the remainder of the fluid returning via passages in the tip sealing valve assembly 8 and central tube 7.

A liquid-tight fitting for an electric heater in a kettle of thermoplastic material (particularly the kettle described in Specification 840,567) is provided by means of a sleeve 11, Fig. 3. which is inwardly flanged at its inner end 112 and has an annula projection 113 (intermediate its ends 111, 112) bevelled inwards at 116 to accommodate the lower wall A<SP>1</SP> of the kettle. The lower half of the kettle is moulded round the sleeve 11 and the assembly is removed from the mould whilst the kettle is in a plastic state. In this way when a locking ring 13 is tightly screwed on to sleeve end 111 the wall A<SP>1</SP> is dovetailed into the region 116 between the ring 13 and projection 113. Alternatively, this projection may be provided with one or more annular slots 117, Fig. 4, into which the plastic wall of the kettle is pressed by ring 13. The heating element is threaded through sleeve 11 so that its base block abuts against resilient washer 14, the base block being held in place by means of a protective collar which is screwed into the internally threaded bore 115 of the sleeve 11.

Abstract: 453,631. Lifting and manoeuvring motor vehicles. GANGLER, P., 53, Panoramastrasse, Esslingen, near Stuttgart, Germany. Dec. 12, 1935, No. 34451. Convention date, May 6. [Class 79 (iii)] For lifting and traversing one end of a motor vehicle, an auxiliary or spare wheel 5 is mounted on a crank arm 3, engine operated gearing being arranged to rotate the crank arm through 180‹ for lifting and to rotate the wheel in either direction for traversing. The crank arm 3 carries the wheel 5 on a pin 4 and is integral with or secured to a cast steel or like disc 2 forming a rotatable front to a casing 1, being retained in an annular seating 1<c> therein by a bolted ring 1<d>. The casing 1 is shown located under the luggage carrier 50 and formed with lateral extensions 1<a>, 1<b>, whereby it is suspended from the spring shacklebolts 51a of the chassis frame, being further secured by a V-shaped truss tube 41 passing through a lug 140. A shaft 6 from the engine is connectible through a reverse gear box 7, controlled through a lever 7b, and cords 32, 33, to shafting 8, 8<1>, terminating within the casing 1 and serving through skew gearing to drive a worm 10 in mesh with a worm wheel 11, the hub of the worm wheel being connected by dog teeth to a sleeve 15 on a supporting spindle 12. The sleeve 15 drives a train of gears 161, 171, 17<11>, 16<11> on the face of the crank arm, the gear 16<11> rotating the wheel 5 by means of a pin 55. The inner end of the sleeve 15 carries a clutch ring 13 adapted to be expanded into engagement with a flange 21 on the inner face of the crank disc 2, by the action of a conical sleeve 26 on the usual clutch arm 30, the sleeve being slid by pulling a cord 18 to rock an arm 19 on a shaft 2 carrying a toothed sector 28 engaging rack teeth 29 on a yoke 29<1> engaging an annular groove 26<1> in the sleeve. Thus the wheel 5 is rotated on its axis as soon as the drive is put into action, the crank arm being rotated through 180‹ when the cord 18 is pulled to engage the clutch 13. To retain the crank arm in its upper and lower extreme positions, a pivoted lever 24 thereon is provided with a lug 341 which under the tension of a spring rides on the periphery 1 f of the fixed casing 1 and drops into an upper or lower recess 25 therein, the periphery being formed with rises 1<h>, 1<i> to increase the tension on the arm as it approaches the recesses. To disengage the lug 24<1> when the clutch is engaged, levers 20, 21 on the casing 1 are connected by links 22, 23 to an arm 19<a> on the cone sleeve operating lever 19.
