In a first embodiment a disposable rigid separation/irradiation chamber (14) is provided with a cylindrical outer compartment located within the drum and opposing the radiant energy source (2). Whole blood is supplied to the chamber through ...

In a small-sized motor with a worm reduction gear wherein a worm, an armature and the like are coupled onto the outer periphery of an intermediate portion of a motor shaft and fixed thereto; the motor shaft is inserted into a gear case, whereby a worm wheel is meshed with the worm; a journal member having the outer diameter larger than that of the worm is projectingly provided at a position close ...

A method of degassing and decarburizing molten stainless steel in a vacuum, which molten steel is produced in a steel making furnace. Molten steel is foamed in a vacuum tank. Before foaming the [N](%) in the molten steel is increased. The foam is produced by denitrification of the steel during vacuum degassing. Oxidizing gas is blown through a top-blow lance onto the surface of the steel in a vacu...

A system and method are disclosed for controlling a shift even in a transmission (14) wherein a shift actuator (30,48) develops a force to effect the engagement of a clutch collar and a gear. The method comprises detecting when a non-fully engaged condition of the clutch collar and the gear occurs, indicating either a tooth butt or torque lock condition, and then pulsing the shift actuator (30,48)...

A process for producing a substantially non-explosive powder containing finely divided metallic particles suitable for being incorporated in a refractory mixture, comprising simultaneously grinding a mixture of pieces of metal with pieces of an inert refractory material to produce a premixture containing finely divided metallic particles and finely divided refractory particles which are intimately...

A bobbin winder assembly, to lead the yarn end to an empty bobbin sleeve, has a retainer formed by the first yarn guide (31) at a controlled drive (33). The drive moves the yarn guide (31) from a guide retention position into a yarn release setting, in a swing movement. The second yarn guide is the opening (30) of a suction unit. When the yarn is to be caught through the catch (4), the first yarn ...

To transfer a running yarn fed by suction to an empty bobbin sleeve, the sleeve is fitted to the bobbin winder and rotated. The yarn is laid at the rotating yarn catch to be caught by it. Through the rotation of the yarn catch, the cutter is initially moved in when the yarn catch is displaced from the side of the winder where the yarn is fed in. Also claimed is an appts. with a yarn cutter (...

Methods for making, methods for using and articles comprising cermets, preferably cemented carbides and more preferably tungsten carbide, having at least two regions exhibiting at least one property that differs are discussed. Preferably, the cermets further exhibit uniform or controlled wear to impart a self-sharpening character to an article. The multiple-region cermets are particularly useful i...

A gauging system for monitoring channel depth in percutaneous endocardial revascularization surgery, includes a catheter (14) for percutaneous insertion into a heart chamber, including a source (23) of tissue ablative energy for ablating a part of the wall of the heart chamber where a channel is to be created; a sensor device (24) proximate the distal end of the catheter (14) for sensing a boundar...

Pointing device for a personal computer (EL) comprising an optoelectronic transmitter (TX), provided to be associated with the screen (MON) of the personal computer (EL), and an optoelectronic receiver (RX), provided to be made integral with the head of a user for the personal computer (EL), for example by assembling it on a pair of eyeglasses (OC), in order to allow moving a cursor on the screen ...

The invention realtes to a process for producing foams based on polyisocyanates by reacting polyisocyanates, compounds having at least two hydrogen atoms reactive towards isocyanate groups, blowing agents and, if appropriate, further additives. In this process, a blowing agent is used which is composed to the extent of at least 10 mol % of one or more fluoroalkanes of the formula I CaHbFc where a=...

Metal lumps or pebbles are produced by introducing a molten metal stream into a stream of water in a direction which is substantially the same as the direction of the water stream and at a velocity which is substantially the same or slightly less than the velocity of the water stream.
