This invention relates to a cleaning apparatus for cleaning workpieces such as semiconductors and other electronic devices by using chloro-fluoro-carbon solvent such as R113. Chloro-fluoro-carbon vapor is drawn from a lateral position of a layer of chloro-fluoro-carbon vapor through a suction duct and is cooled and liquefied in a collecting tank. The resulting liquid is returned to a cleaning tank...

To avoid inadvertent uncoupling of a Monorail catheter (10) from its guidewire (22), the guidewire eye (20) or port is identified by a radiopaque marker (28) so that the surgeon can perceive the location of the distal end (14) of the guidewire (22) relative to the catheter's guidewire port (20) on a fluoroscope screen.

A receptacle (42) mounted in the administration set (20) is adapted for receiving a cartridge (44) containing the beneficial agent. Also disclosed is an adapter (160) for connecting the cartridge (44...

The invention relates to an improved cardioplegic solution for reducing ischemic damage to the heart during operations and/or transplantation. The invented solution contains adenosine, hypoxanthine and ribose in addition to the electrolytes contained in standard cardioplegic solutions.

A titanium oxynitride film, method for its production, and coated articles comprising titanium oxynitride in combination with other metal-containing films are disclosed.

In a device for processing workpieces by laser, having a gas nozzle directed at a working point with the nozzle coupled via a control valve (15) to a gas container, the gas supply container (16) has a closed flow channel (1) provided with a gas inlet valve (4). In the channel, gas is power circulated at high speed, e.g by a turbine wheel (2) in a housing (10) for the closed channel and driven by...

Method and apparatus for bending and quenching a glass sheet by picking up the hot glass sheet using a movable suction plate which brings it above a peripheral bending ring with a concave profile and releases it onto this ring, where the sheet acquires its curvature and on which it is quenched by blasting cold air onto its two faces. According to the invention the glass sheet is brought direc...
