Abstract: A handle assembly for a pressurized dispensing container consists of a handle 12 and a collar 11. The collar is fitted with legs 28, provided with bulbous portions 29 which clip resiliently into a groove 20 in the valve cup. The handle is provided with lugs 41 which engage with the collar. The handle is inserted into the collar and twisted to engage the lugs 41 with the collar to retain the handle. The lugs also press against legs 28 to prevent the collar becoming detached from the cam 13. A rachet surface 30 is provided around the top of the collar which is engaged by a tab on the handle as the handle is twisted to lock it into the collar. The rachet surface thus prevents the handle from being disengaged by being twisted in a direction opposite to that required for engaging the lugs.

Abstract: The invention relates to a method for manufacturing tubes by sintering and infiltration, the characteristic features of the invention being that the tube wall is formed from a metal powder on a mandrel and is sintered and that the tube wall, during one sintering stage, is sealed by infiltration by means of an infiltration material which solidifies in situ when the temperature is lowered after sintering and which is capable, when in the liquid state, of wetting the metal powder particles, the molding of the tube from the metal powder being preferably carried out by a wet or dry pressing process or by extrusion of the metal powder.

Abstract: Powders with a relatively low bulk density can be emptied from transportation containers only with a large and undesired production of dust. The apparatus for emptying powder-filled containers consists of a suction tube on which a fluidizing device is arranged in the neighborhood of the open end of the tube. This fluidizing device can have the form of a double-jacketed cone concentrically about the tube, or a hollow sphere concentrically about the tube. Fluidizing air can be introduced into the powder through bores arranged in the direction of the opening of the tube. To prevent the suction tube being sucked onto the container wall, the opening of the suction tube has a crenelated edge.

The fuse unit includes a pair of spaced apart U shaped fuse clips axially aligned about the longitudinal axis of a cartridge fuse. The fuse clips each have two mutually opposed wing contact portions that are substantially parallel to the longitudinal axis. The broad contacting surface area of the wing contact portions are capable of making contact with a load or line contact. The base member has an opening therein for receiving the fuse unit. The base member has a load and line contact each of which includes a base portion and two resilient side strips that are closely adjacent to each other. Each side strip is independently biased towards the opening in the base member and lies on a plane normal to the longitudinal axis.

Abstract: Disclosed is a continuous or discontinuous process for coking high-boiling aromatic hydrocarbons to form high grade carbon products having only a narrow range of variation of physical and chemical properties. High-boiling aromatic hydrocarbon mixtures are coked in thin layers according to a defined temperature/time program, and the functional relationship between layer thickness and optimum coking time, which applies to that program for the particular hydrocarbon mixture used, is determined by means of a simple preliminary experiment. A small quantity of the hydrocarbon mixture used is coked on a microscope hot stage under standardized conditions to determine the minimum coking temperature, the time to the final coking temperature and the dependence of coking time on the layer thickness.
