Abstract: A transportable container for handling powdered, granulated or other particulated solid materials, having a tapering lower wall portion of hopper form and a discharge opening at its base, the opening being normally closed by a valve member which is movable upwardly into the interior of the container to define an annular opening between its periphery and the internal surface of the container wall, retaining springs being provided within the container and arranged to hold the valve member in its closed position until lifted by, for example, a probe fixed relative to a material receiving member onto which the transportable container may be lowered. This inventionTHIS INVENTION concerns the handling of powdered, granulated or other particulate solid materials. Such materials will hereinafter be termed materials of the kind referred to.Materials of the kind referred to are widely used by the process industries and are normally dispensed for use from bins or hoppers.

Abstract: A transportable container for particulate solid material and receiving means for the container which is adapted to removably receive the container and which is capable of being actuated to promote flow of material from the container.

Abstract: A mounting bracket for supporting either end of a roller or other blind is formed in two pivotally connected parts one of which is adapted to be secured to a part of the blind mechanism and the other of which is angularly movable through 180.degree. relative to the first part and can be secured to either a horizontal or vertical surface as desired.

Abstract: Rotary piston engines of the kind in which the air inducted into the working chambers of the engine passes through an induction passage which is formed in part in the rotary piston of the engine, the rotary piston thereby being cooled by the air flow therethrough, a member is secured to the main engine housing which forms an air reservoir chamber having at least the same and preferably twice the volumetric displacement of the engine in the induction passage between the part thereof formed in the rotor and an inlet port to the working chambers.

Abstract: A platform weighing scale having a load receiving platform structure positioned over and resting on a multiplicity of load cells and having a load cell-removing aperture in registry with each load cell whereby each load cell is upwardly removable through its associated load cell removal aperture.

Abstract: Reserve fuel tank for motor vehicles and the like includes an air-tight reservoir having inlet and outlet tubes so that it can be connected between the main fuel tank and the engine or other fuel consumer. In a main feed position the outlet opens from an upper region and the reservoir is automatically filled with fuel by the flow from the inlet, and preferably said flow impinges on the outlet so that some fuel passes straight through. In a reserve feed position structure of the device is rearranged so that the outlet opens from a lower region to draw fuel from the reservoir, for example by inverting the reservoir, or inverting or lowering an outlet tube or a combined outlet and inlet tube. A simple and cheap construction is provided, avoiding the need for valves or cocks.

Abstract: The method for the random dyeing of yarn in which yarn slivers are laid in a tensionless zig-zag formation onto a travelling stenter pin chain conveyor, applying longitudinal rows of stitching or tape to anchor the yarn slivers in position and to take the tension of feeding the yarn slivers through rollers which apply dye liquor of differing colours or shades in longitudinal stripes and fixing, washing and drying and heat setting the slivers and finally rewinding the individual yarn slivers onto separate yarn packages to produce yarn randomly dyed throughout its length.

Abstract: A pelletising machine of the kind comprising an annular die having radial bores therethrough, and adapted to be rotated about its central axis, whereby material introduced into the centre of the die is extruded through the bores by the action of freely rotatable pelletising rollers which are closely spaced from the inner peripheral surface of the annular die, and having a door which can be hinged between an open position enclosing the die, there being a cut-off knife mounted on the end of a shaft extending through the wall of said door, characterised in that the shaft supporting the cut-off knife passes through a guide sleeve carried in a housing secured to the wall of the door, there being means to permit fine adjustment of the position of said shaft axially within said guide sleeve and means permitting said guide sleeve together with said shaft to be moved as a unit rapidly outwardly relative to said housing and returned inwardly to their initial position.
