A method and apparatus applying a laser beam to a working surface, by displacing the laser beam to trace a plurality of circular scans over the working surface; and continuously varying the diameters of the circular scans at a rate to produce a substantially homogenous distribution of the laser energy over the working surface.

The invention relates to a simple method for producing a concrete composition comprising cement as well as the known solid components for this purpose, using furnace slag as the main constituent, being characterized by the fact that sea water is used for obtaining the respective concrete. The concrete composition is hardened either after being dipped in sea water, or maintaining the wet compositio...

Despite the extremely flat construction, it is intended significantly to reduce the tendency of the semiconductor chip (1), which is embedded in the plastic housing (10) of the electronics module (M), to fracture. The chip is mounted on the chip island (22) of a system support (20) in the form of a sheet-metal structure (lead frame). The external contacts (21) - which can be partially covered by t...

Also provided is a tool for preparing the n...

A tablet containing dirithromycin Form II.

A process for separating an anomeric mixture of alpha and beta 2-deoxy-2,2-difluoro-D-ribofuranosyl-1-alkylsulfonates by contacting the anomeric mixture with a solvent; heating; adding a countersolvent; and lowering the temperature.

Morpholinyl derivatives of doxorubicin having the general formula A: wherein X represents a linear or branched C1-c6 alkyl group or a benzyl group -CH2C6H5, and having (S) or (R) configuration at carbon atom C-2" of the morpholino ring, are antitumor agents.

A filtration system and assembly for a wide variety of liquid mixture applications is disclosed. The system comprises a pump, filter, concentrate release, aspirator, and by-pass that incorporates a flow control valve. The flow control valve controls the flow and pressure of the fluid recycling within the system thereby simultaneously controlling permeate outflow from the filtration system and feed...

The present invention refers to a system for packing, storing and transporting, particularly in a vertical position, stacks of sheet material such as glass, metal, plastic and large marble plates. The invention provides, for use in packing, storing and transporting sheet material, a sheet material protecting unit including two complementary protecting elements, each including a substantially plana...

An interactive videotex system with distributed processing and storage of video picture information in nodes (12) disposed throughout a cable television distribution system. The nodes (12) are coupled to the feeder cable (30) of the cable distribution system. Each node (12) in the system receives a substantially identical copy of the interactive video picture information and related data from a re...

The pallet container (1) for liquids has an exchangeable inner container (2) made of sheet metal, an outer casing (6) of latticework and a pallet (9) which is designed as a bottom tray (10) and receives the bottom (16), designed as a drainage bottom, of the inner container in a positive-locking manner. The inner container (2) of sheet metal, preferably of dual-walled design, is welded together fro...

Disclosed is a trehalose-releasing enzyme which specifically hydrolyzes the linkage between a trehalose moiety and the remaining glycosyl moiety in a non-reducing saccharide having a trehalose structure as an end unit and having a degree of glucose polymerization of 3 or higher. The molecular weight of the enzyme is about 57,000 to 68,000 daltons on SDS-PAGE, and the isoelectric point is about 3.3...
