Abstract: In an example, a substrate is oriented to a target axis, wherein a residual angular misalignment between the target axis and a preselected crystal channel direction in the substrate is within an angular tolerance interval. Dopant ions are implanted into the substrate using an ion beam that propagates along an ion beam axis. The dopant ions are implanted at implant angles between the ion beam axis and the target axis. The implant angles are within an implant angle range. A channel acceptance width is effective for the preselected crystal channel direction. The implant angle range is greater than 80% of a sum of the channel acceptance width and twofold the angular tolerance interval. The implant angle range is smaller than 500% of the sum of the channel acceptance width and twofold the angular tolerance interval.

Abstract: Modular elements for composing disassemblable walls, cabinets, writing tables and other pieces of furniture comprising:panels;box-like metal sections provided on three surfaces thereof with a groove defining a longitudinal slot of a width lower than that of the groove while from the remaining surface, anchoring means extend outwardly to connect each section to a panel;column devices having, at its ends, pieces to be received inside the central grooves of said sections and cooperating with means for locking said pieces in its engaged position, said column housing a hollow tubular pivot member, into which passes a threaded rod having a upper control head and which at its lower end rests on an adjustable ground engaging foot;cylindrical rods for the connection of wall panels, in coplanar relationship;expansion screws to be inserted into the front grooves of the sections for carrying hooks, and the like;hinge devices for the connection of adjacent wall panels at right angles and to allow said panels to be fold on

Abstract: A stamping press, as for stamping molded articles out of a plastic web wherein the articles are premolded, has a fixed stamping tool section accurately secured on the press frame and a movable tool section slidably mounted on fixed columns on the fixed tool section and connected by operating linkage to power driven devices on the frame, the linkage including adjustments for tool alignment, stroke and frequency. Push rods in the linkage transmit movement to the movable tool section from cam controlled rocker arms, and the push rods are removably hinged to the movable tool section to disconnect and remove the latter. Secondary devices such as ejectors and further tools are actuated in synchronism with the stamping tool.

Abstract: Thin-walled articles of thermoplastic material are formed in a continuous apparatus starting with heating and extruding granular thermoplastic raw material in the form of a continuous web which is immediately stabilized by rapid cooling of its opposite surfaces and the stabilized web wherein the material sandwiched between the precooled outer surface layers remains at or near extrusion temperature is fed into a thermal forming station wherein shaping tools form the articles in the web without the need for further heating of the web. Adjustments are provided for correlating the cooling action to different materials and web feed rates, for varying the web feed rates and increments, and for varying the shaping tool movements to adapt for different materials and sizes of articles. After the formed articles are separated from the web the web residue is fed back to be mixed with incoming raw material at the extrusion station.

Abstract: A freely flowable pancreatin of high amylolytic, lipolytic, and proteolytic activity, of a low germ content and substantially free of pathogenic germs and fibrous tissue material, of a high bulk weight between about 500 g./liter and about 700 g./liter and a very fine particulate size is produced according to the continuous process of extracting finely comminuted pancreas glands with a mixture of chlorinated hydrocarbons and fluoro-chloro-carbons and, if required, water, separating the fat-containing solvent phase, and recovering pancreatin from the enzyme phase.

Abstract: A container assembly wherein an initially filled container and its closure cover have coextensive flat edge regions attached by welds and also have independent snap fit connection. To safeguard against unauthorized opening and reclosing, provision is made for producing a tear line pattern in the cover upon detaching the edge regions at the welds, such rendering the edge regions incapable of undetectable reassembly to initial cover closed condition, but not affecting the ability of the snap fit connection to more or less temporarily reclose the assembly.
