Title: Improvements in and relating to gas cocks
Inventor: TAULIER HUBERT
IPC: F16K37/00
Filed: 1968-12-19
Abstract: 1,222,390. Valves. ELECTRICITE DE FRANCE (Service National). 19 Dec., 1968 [27 Dec., 1967], No. 60417/68. Heading F2V. A gas cock comprises a body portion 4 formed with an inlet 1 and an outlet 2 and with two coaxial bores 5, 7 of different diameters, the inlet being in communication with one of the bores and the outlet being in communication with the other bore, a piston 9 located in the larger diameter bore, sealing means 19, 20 arranged between the piston 9 and the body portion, a second piston 8 slidable within the smaller diameter bore 7 and secured to the piston 9 so as to move axially with it, a plurality of sealing rings 16 mounted on the piston 8 to seal the inlet from the outlet, screw means 12 for axially moving the piston 9, and a stop 18 adjustable to allow successive ones of the sealing rings 16 to engage the bore 7. The piston 9 houses anti-friction bearings 10, 11 so that rotation of the rod 12 does not cause rotation of the pistons 8, 9. An aperture 22 allows a chamber 21 to communicate with the atmosphere. The screw 23 is not initially tightened so that any gas leakage past the sealing ring 19 visibly expands an elastic sleeve 25. In an alternative construction, the outlet 2 is coaxial with the bores 5 and 7.

Title: Production of Foamed Sheet Materials
IPC: D06N3/00
Filed: 1978-11-03
Abstract: Textured effects are given to foamed sheet materials by application to a substrate web, e.g. paper, a foamable thermoplastic polymer composition containing a heat decomposable blowing agent. Prior to, or simultaneously with, the application of the foamable composition, a composition containing thermally expandable thermoplastic microspheres containing a volatilisable liquid is applied to the substrate web. The laminar product is then heated to effect decomposition of the blowing agent with consequent foaming and volatilisation of the liquid in the microspheres. The amount of microspheres employed is such that in the areas to which both the microspheres and the blowing agent containing composition is applied, the weight of microspheres is 1.5 to 10% by weight of the binder material in the foamable composition.

Title: Steering valve arrangement for a vehicle
IPC: B62D5/08
Filed: 1979-08-02
Abstract: A steering valve arrangement for a hydraulically operated steering system of a vehicle has two spring-loaded, seat-type inlet valves 22a and 22b which are closed in the neutral position of the steering system so that the supply from a pressure medium source to the respective working chambers of an adjusting motor is cut-off. The valve members 38 of the inlet valves co-operate with valve seats 24 formed in an outer rotary member 12 which is resiliently connected via a torsion bar 16 to an inner rotary member 14 in operative connection with the steering wheel of the vehicle. Each valve members 38 is urged on to its valve seat 24 by a respective bow-like spring 36 accommodated in a substantially annular chamber 18 which is formed in the outer rotary member 12 and which constitutes a discharge chamber in communication with a working chamber of the adjusting motor. The valve 22a can be opened, on rotation of the inner member 14, via a tappet 46 which by way of a fine control spring 40 acts on the end of the spring 36. In operation the valve spring 36 counteracts the force produced by pressure drop at the valve 22, and the members 14, 46 operatively connected to the vehicle actuating means (steering wheel) so engage the valve springs 36 that with a steering movement the force of the valve spring 36 corresponding to the steering direction is reduced. <IMAGE>

Title: Powder applicator
IPC: B05B5/03
Filed: 1979-08-13
Abstract: A powder applicator for applying powder to form side stripes on the interior of can bodies B along side seams thereof includes a device for providing a layering effect on the gas-entrained powder so that although the powder is normally carried by the gaseous stream it is directed into an orifice 24 of a nozzle 21 as a dense stream with the carrier gas forming a separate layer. This separation takes place centrifugally in a loop 22 in the supply conduit 17. In addition, the applicator forms a seal with the interior of the can body to define a limited sealed area within which the powder may pass. This sealed area contains corona charging pins 41 which are arranged in a longitudinal line so that a maximum charging of the powder may be effected. Also, a diffused gas is directed into the sealed area to prevent the powder from clinging to the side walls of the sealed area and the charging pins. <IMAGE>

Title: A strip assembly primarily for use as a guard strip
IPC: B60R13/04
Filed: 1980-12-06
Abstract: A strip assembly comprises a main strip element (10), formed as an extrusion of rubber or other flexible and resilient wear-resistant material, and a metal retaining strip (15), which is preformed with longitudinally spaced holes. In its unstressed form the main strip element has a longitudinal recess (12) in a front face thereof with undercuts (13) in both sides; its rear is hollow, the rear face (14) being of arcuate shape in cross-section. By resiliently deforming the main strip element the retaining strip is fitted into the recess and retained in the undercuts. The assembly can be secured against a flat surface (16) by means of screws (18) extending through holes in the retaining strip and aligned holes in the main strip element. This causes the rear face to flatten and closure portions on each side of the recess to abut each other and so close up the recess, concealing the screws and the retaining strip. <IMAGE>
