Abstract: a braided sleeve is formed from a tow of flexible filaments such as glass fibers and a rigid filament such as a stainless steel wire. The rigid filament reduces the tendency of a braided sleeve to fray at its ends, and can cause the end portions of the sleeve to taper inwardly, which can enhance the thermal insulation properties of the sleeve. The sleeve may be coated with polymeric material.

Abstract: A sliding and pivoting joint, and a retractable medicament spray dispenser having such a joint. A sleeve is telescopically mounted on the dispenser housing by engaging a pair of pin-like projections on a pair of ears on the sleeve into slots which are in opposite side walls of the housing. An elongated stud protrudes perpendicularly from the inward end of each pin. When the sleeve has been telescopically extended relative to the housing, abutments in the housing interact with the protruding studs to prevent the sleeve from being pivoted to any positions beyond those which correspond to the storage and the operating configurations of the dispenser.

Abstract: Pneumatic switching devices do not constitute a danger in explosive surroundings contrary to electrical switching devices with which sparking may occur. Known pneumatic devices have the disadvantage of a long actuation path, whereby they can arrive at a so-called "cutting" position. Moreover, they are not suitable for actuation by the very sensitive pressure pick ups constituted by membrane pistons. Also the known pneumatic switching devices have large dimensions. The invention removes said disadvantages in that the switching device has a piston provided in a housing, a switching chamber and a pressure chamber being formed between the housing bore wall and a narrowed piston portion.

Control means consisting of a button or key selectively control the movements of the links under the action of the biasing means.

Abstract: The high pressure of a gas transport network must be reduced before the gas is admitted to a distribution network to which consumers, e.g. household appliances are connected.This reduction is carried out by a gas pressure control installation. If this installation fails, conduit failure, appliance failure, explosion and fire may occur.A known safety device has a closing spring, which closes a valve if the gas pressure unacceptably rises which causes release of the spring by the gas pressure. The movement releasing the spring is influenced by friction which may have an uncertain value. The invention eliminates friction in that the reduced gas pressure acts on the valve via spring loaded membranes, namely a measuring membrane and an actuating membrane.
