Title: Improvements relating to pneumatic vehicle suspensions
IPC: B60G17/04
Filed: 1960-05-10
Abstract: 943,253. Adjusting height of vehicle suspensions. DUNLOP RUBBER CO. Ltd. May 10, 1960 [May 21, 1959], No. 16416/60. Heading B7D. A pneumatic suspension system for a vehicle includes means for preventing transmission to a levelling valve of the relative movements between chassis and axle which normally operate it. The operation is prevented by a pneumatic locking cylinder 1 containing opposed free pistons 2 and 3. Air pressure, when admitted to spaces 13a and 14a by way of channels 12 and 11 cause the pistons 23 and lock a rod 7 to a fixed collar 4 so that the rod is no longer free to move inside the cylinder. The rod is attached to the control of a levelling valve on the chassis and the cylinder 1 to the axle by way of rubber bushes 18 and a collar 16 so that the levelling valve only operates when the rod is locked. Releasing the pressure on the pistons frees the rod again. Fig. 3 shows an embodiment in which the locking cylinder 1 is integral with the levelling valve cylinder 19. Relative movements of axle and chassis are here transmitted through a spring 22 to a cylindrical head 21a on an arm pivoted at 21 and thence to a similar head 23a on a centrally pivoted arm 23 whose other end operates tappets 26 and 27 of the outlet and inlet sides 28 and 29 of the levelling valve. Pressure admitted at 13 and 14 can cause pistons 2 and 3 to move inwards and connect the motions of the heads 21a and 23a, which otherwise will move independently of each other. Figs. 4, 5 and 6 (not shown) illustrate vehicles with arrangements of air-springs, pressure plant and levelling valves controlled by locking cylinders whose air is supplied through a poppet or other valve coupled to a switch on the dashboard and/or electrically or mechanically to the vehicle's accelerator pedal or to contacts which are closed when the vehicle doors are opened. Specification 875,692 is referred to.

Abstract: 790,437. Making cigarette filter tips. BRITISH CELANESE, Ltd. June 8, 1956 [June 10, 1955], No. 16742/55. Class 130. [Also in Group IX] A tow 7 of aligned cellulose acetate fibres is sprayed internally by a device 18 with a bonding agent in the form of an aqueous film-forming solution of a water-soluble cellulose derivative after the fibres have been opened out by air jets 14, the sprayed tow 23 passing to drying and filter-rod forming mechanism such as a heater having a coacting pair of rubber-covered rodshaping rollers upstream and a further roller pair downstream thereof. The tow is largely forwarded by the jets 14 so that it is under only slight tension from the first pair of rollers. The device 18 comprises an air supply nozzle 17 playing across the end of a tube 19 leading from a derivative supply 22. The sprayed tow may be subjected to further air jets in a tube slightly greater in length and diameter than the tube 11 before passing to the first pair of rollers, which may in all cases be replaced by a die or a series of (e.g. two) dies of successively smaller diameter. The fibres used are crinkled either mechanically after manufacture, as by forcible feeding by rollers into a confined space from which their emergence is resisted, or by dry-spinning a solution of cellulose acetate in acetone at high extrusion speeds and collecting the extruded filaments without tension. The derivative used may be methyl cellulose or methyl hydroxy-ethyl cellulose. Reference is made to forced feed of the derivative, to a highfrequency electric dryer in place of the heater and to more than one assembly of further air jets, some of which may be operative on the shaped rod. Quantitative process examples are given. Specification 665,278 is referred to.

Abstract: 145,507. Siemens - Schuckertwerke. Aug. 30, 1918, [Convention date]. Controllers.-In a regulating switch of the resistance-liquid type for motor starting, the immersion surface and the distance apart of the electrodes are varied simultaneously, by operating mechanism which both varies the immersion of one electrode and at the same time varies its distance from the fixed electrode. In the arrangement shown, the sickle-shaped movable electrode 1 is carried by a shaft 4 rotatable by the handle 5 so as to move the electrode into the resistance liquid in the vessel 3 which contains also the fixed electrode 2. The shaft carries a barrel 9 with a cam-groove 10 engaging with a stationary pin or roller 11 so that, as the shaft is rotated to immerse the electrode, it is also moved longitudinally to bring the electrode nearer to the fixed electrode. Both movements of the electrode take place simultaneously, but the mechanical means for producing them may be independent of each other. A number of cam-grooves may be provided and any one of them made effective so as to give different relations between the rotary and transverse movements of the electrode. The vessel that contains the liquid may be raised and simultaneously moved transversely to produce the same result.
