Abstract: This invention provides a process and apparatus for the wet attrition of ore. The process comprises grinding the ore to a pulp having a particle size distribution such that about 80% by weight of the particles have a diameter of from about 30 to about 0.4 mm; and agitating the pulp in a slightly turbulent medium. The apparatus comprises a vat having top and bottom covers with central openings and a gutter disposed along the exterior circumference of the top of the vat; a cylindrical shaft extending through the opening in the top cover; and a pair of impellers mounted at a distance apart on the shaft, the blades of the impellers being so arranged that the pulp is pumped towards the space defined between the two impellers.

Abstract: An improved process for shaping the edge of a combustion chamber recess in the piston head of a finish-machined light-alloy piston is disclosed wherein the piston is moved past the oscillating charged carrier beam at an angle of inclination of 40 DEG  to 50 DEG , the charged carrier beam is caused to act on that portion of the rim of the combustion chamber recess which is to be refined by being remelted and the charged carrier rays are moved over said portion only once. The process presents the formation of cracks at the edge of the chamber.

Abstract: PCT No. PCT/DE81/00064 Sec. 371 Date Dec. 11, 1981 Sec. 102(e) Date Dec. 11, 1981 PCT Filed Apr. 18, 1981 PCT Pub. No. WO81/03037 PCT Pub. Date Oct. 29, 1981.A method for the pneumatic insertion of the weft thread (24, 24a) into the shuttles (9) of a multi-feed weaving loom. The weft thread (24, 24a), of a respectively predetermined length, is inserted by means of an air flow in an injector (23) into the weft thread magazine (29) of a shuttle (9) traveling in a continuous movement past the injector (23). In order to be able to supply the shuttles (9) rapidly with the particular weft thread required for the fabric panel width in a multi-feed weaving loom, without thereby causing an impermissible strain on the weft thread or being required to extend the length of the weft thread magazine (29) of the shuttles (9), the injector (23) is moved conjointly with the shuttle, e.g. by a gear coupling (34-38) beginning at a start position (I) but, at a slower speed than the shuttle and over shorter distance during the insertion of the thread (24, 24a) into the weft thread magazine (29). At the end of this distance the injector is rapidly returned to the start position by a spring (42).

Abstract: A bubble pack is formed from two sheets welded or heat sealed together, the bubbles forming medicament (25) accommodating chambers (8). The strength of the resulting package is such that a child can neither force a pill from its chamber (8) nor breach the chamber by tearing the package inwardly from its edge, manually. Along an edge of the package is a row of notches formed by intersecting edge portions (9, 10), each notch optionally having an inwardly-directed incision (11) at the root (12) thereof. The notches assist tearing of the package which will yield to a force an adult can muster but not musterable by a child. <IMAGE>
