An adapter for connecting a tyre-inflating valve to an inner tube comprises a substantially T-shaped body member 23 with a pair of oppositely disposed openings 32, 33 each communicating with the interior of the inner tube, a plug 44 in one of the openings, and an extension tube 37 with a valve core or insides 41 at its outer end in the other of the openings, the positions of the plug member and the extension tube being interchangeable so that the direction of extension of the extension tube may be selectively determined. The body member 23 has a flared portion 24 which is screwed to a threaded spur or bush 22 vulcanized to the inner tube 4. The flared portion 24 has a flange 25 with ribs 26 sealing against the inner tube. A bore 29 in the spur communicates by passages 28, 30 with the openings 32, 33 which are threaded to receive a coupling nut 39 for the tube 37 and the plug 44 respectively. The openings 32, 33 have conical seatings at their inner ends. In a modification the vertical limb 27 of the body member 23 is screwed into the spur or bush 22. The adapter is particularly suited to wheel assemblies with twin tyres as in the case of assemblies with a non-directional tread, a spare rim and tyre assembly having the adapter may be used for any one of the four tyres of a wheel pair. In the case of tyres having a directional tread, two spare rim and tyre assemblies only would be required for a wheel pair, one with the sealing band or gutter portion 16 of the rim one side and one with it on the other. Fig. 2 shows a twin tyre assembly on a wheel 8, the rims 6, 7 having a spacer 9. The inboard tyre 3 has an extension tube 54 of flexible steel, rubber, or plastic of sufficient length to extend to the vicinity of the valve 36 of the outboard tyre 2.
Patent GB-367481-A (GB)
Title: Improvements in the manufacture and production of the carbonyls of molybdenum and tungsten
IPC: C01G39/00
Filed: 1930-12-03
Abstract: Molybdenum and tungsten carbonyls are prepared by the action of carbon monoxide under pressure on materials containing said metals which have been reduced in the presence of copper or its compounds, and also, if desired, heavy metals such as iron or their compounds. Ores or waste products containing copper with or without the said heavy metals may be used, and the amount of copper should not be below for example 1 per cent of the total reduced mixture, or about \ba1/2\be per cent if other heavy metals are present.  Sintering may be avoided by carrying out the reduction at a temperature below say 500 DEG  C. or by subsequent rapid cooling if higher temperatures are used, by addition of materials such as alumina, magnesium sulphate or calcium oxide, or by reducing with carbon rich in ash.  Carbonyls formed from the cupriferous materials may be separated by distillation or crystallization, or the amounts of these materials may be so chosen that an alloy of a desired composition is obtained by thermal decomposition of the resulting carbonyls.  The residue from the carbon monoxide treatment may after purification and reduction be re-used until practically all of the molybdenum or tungsten is removed, and then added to fresh initial material. The action of the carbon monoxide on the reduced material may take place at temperatures above 210 DEG  C.  According to examples, molybdic or tungstic acid together with copper nitrate is reduced at 800 DEG  C. by hydrogen, and then treated with carbon monoxide under a pressure of 200 atmospheres at 200 DEG  C.ALSO:Alloys containing molybdenum or tungsten or both are obtained by thermal decomposition of the metal carbonyls formed by the action of carbon monoxide under pressure on materials containing said metals which have been reduced in the presence of copper or its compounds.  The copper-containing additions may be ores or waste products, and may contain in addition iron or other heavy metals, or compounds thereof, which themselves form carbonyls. The amounts of additional substances may be so chosen that the resulting carbonyls yield, on thermal decomposition, an alloy of a desired composition.

Title: Improvements in or relating to vehicles
IPC: B60G17/033
Filed: 1970-07-30
Abstract: 1,269,486. Controlling suspension height. FIGHTEL & SACHS A.G. 30 July, 1970 [5 Aug., 1969], No. 36926/70. Heading B7D. In a motor vehicle having a superstructure supported on two axles by spring suspensions, and height adjusting means between one axle and the superstructure controlled by level regulating means responsive to height measuring means between that axle and the superstructure, further height measuring means connected between the other axle and the superstructure is connected to the regulating means so that the regulating means responds only to differences between the deviations from ideal height of the two axles. In Fig. 5, an hydropneumatic suspension element 10 connected to the rear axle A of a vehicle is put into selective communication with a pump 11 or reservoir 12 through a rotary or sliding-type levelling valve 7. The housing 7a of the valve 7 is connected by linkage 2 to the rear axle A and the spool 13 of the valve 7 is connected to the front axle B by a bell-crank lever 5, 6 and hydraulic or mechanical transmitting means 4. A spring 8 and hydraulic damping device 9 prevent brief deflections of the axles from influencing the levelling valve 7. When the load carried by the vehicle varies the rear suspension height is adjusted to correspond to that at the front so that the vehicle remains level at a height which will usually be near the ideal height since changes in load normally affect the front suspension height only to a limited extent. In Fig. 8, the adjustable suspension element is controlled by solenoid valves V1, V2 which are energized through a switch 24a, 24b actuated by the armature of a solenoid winding 22 connected to a bridge circuit wherein moving contacts 19a, 19b carried by insulators 21a, 21b are associated with voltage dividing resistors 20a, 20b connected through a switch 25. Separate voltage dividers may be associated with each front wheel, the mean of the two voltages being fed to the solenoid coil or the two voltages being applied to respective coils which individually control separate adjustable suspension elements at the ends of the rear axle A.
