Abstract: The invention is a dispense head for use with a metal beer keg to supply beer under carbon dioxide gas pressure, the keg being of the type having a standard neck fitting including co-axial gas and beer valves operated by insertion of a probe into the neck. The dispense head can be attached to the keg with the probe raised and in this condition a gas shut-off valve closes the gas passageway. This is opened automatically on the lowering of the probe into the neck of the keg which also opens the keg valves. The gas shut-off valve prevents foaming of beer when the dispense head is attached and spraying out of beer dregs when the dispense head is removed from an empty keg.

Abstract: A yieldable mining stilt comprises a tube formed with diammetrically opposite, longitudinally extending slots. A bar spans the tube and has its end portions engaged in the slots. The relative dimensions of the end portions of the bar and of the slots are such that movement of the bar along the slots causes deformation of the tube adjacent to the slots. In use, the bar supports the leg of a roof arch. There may be two bars, one above the other, the upper one reversing the deformation caused by the lower one.

Abstract: A double-valved closure for a container, particularly a beer container, comprises a cup assembly for insertion into the opening of the container and includes a tubular component of plastics material having legs between which a reaction ring can be sprung during assembly of the closure. A downtube is received in the ring and extends from the lower end of the cup assembly into the container and surrounds one of the valves and a spring biasing the valve closed. The valve is carried by the top of the downtube and the reaction ring provides an abutment for the spring for this other valve and which biases the valve closed. The legs are held together after insertion of the reaction ring by means of an outer ring engaging external grooves in the legs.

Abstract: The specification discloses a method of making an aperture-defining frame member, particularly a window-frame, comprising a rigid frame-shaped reinforcement made of e.g. a solid metal section embedded in synthetic resinous material. The method comprises placing the reinforcement in a mould cavity having the shape of the required frame member and locating the reinforcement in the cavity solely by engaging complementary interfitting formations on the reinforcement and on pin-like projections which extend from the cavity walls, e.g., recesses on the reinforcement engaging the ends of the projections. The longitudinal axes of all the projections are parallel to a predetermined plane and the engagement of the end of each projection with the complementary recess of the reinforcement prevents movement of the latter at least in first directions perpendicular to the plane. The projections are located around the reinforcement to prevent movement of the reinforcement in second directions parallel to the plane.
