Abstract: The valve is intended to contain a given residual pressure in the cylinder and is mounted in the cylindrical bore (16) of a connection piece (14) designed to be connected either to a circuit for using the gas, or to a circuit for filling or rinsing the cylinder. It comprises a closing member which is urged in the direction of its closure onto a seat (22) under the action of a spring (26) and counter to the action of the pressure of the gas in the cylinder. In order to permit the filling of the cylinder, the closing member is axially displaceable inside a bush (40) which is removably engaged in the said bore (16) while the spring (26) rests on an element designed to be secured either to the connection pieces (14) so as to keep the valve in the operative position, or to the said bush (40) so as to permit the axial disengagement of the valve together with the bush (40) and the said element.

Abstract: The valve has a residual pressure valve (14) which is known per se, in which however the gas container can be filled through the residual pressure valve. The residual pressure valve (14) is mounted on a stem (32) which is axially displaceable as a result of a cam configuration in such a manner that it assumes a stable operating position under the influence of its spring (24) and an unstable open position under manual action on a filling apparatus (52) counter to the influence of its spring (24).

Abstract: The valve comprises a body containing a closing member with a sealing surface at the intersection of an inlet duct and an outlet duct for the passage of gas, a piston subjected to the action of a spring or the like and a control device being connected to the closing member via a pusher and via a sealing diaphragm arranged between the pusher and the piston. To lengthen the service life of the diaphragm, the diaphragm is associated with a washer comprised of a slightly deformable material.

Abstract: There is provided inner shoe material in the form of breadths or blanks therefrom consisting of a textile fiber structure which is loaded with 50 to 400 parts by weight based on 100 parts by weight of the textile fibre structure of a mixture of synthetic materials comprising at least one styrene--butadiene copolymer and at least one polyvinyl alcohol obtained by substantial or complete hydrolysis of a polyvinyl ester in an amount of 8 to 102 parts by weight based on 100 parts by weight of the styrene--butadiene copolymer wherein the synthetic material optionally additionally contains fillers, pigments, plasticizers, natural resins, synthetic resins and/or stabilizers against heat, light and/or mechanical influences.

Abstract: Formable or formed stiffening materials, especially for shoe capping, consisting of: at least one backing or layer of fibrous material and at least one thermoplastic synthetic resin, optionally containing fillers, plasticizers, dyes, pigments and/or stabilizers against light, heat and/or mechanical influences, which stiffening materials in a given case have an adhesive coating on one or both sides based on a thermoplastic synthetic resin, containing at least 3 parts of an active substance, e.g., carbon black, in 100 parts of thermoplastic synthetic resins.

Abstract: Formable or formed stiffening materials are prepared which are dry and free of fibrous materials and consisting essentially of a thermoplastic synthetic resin containing at least 3 parts of an active substance, preferably carbon black in 100 parts of the resin. Optionally, there are present conventional fillers, plasticizers, dyes, pigments and/or stabilizers against light, heat and/or mechanical influences.
