Patent EP-0295083-A2 (EP)
Inventor: EFTHIMION PHILIP DR
IPC: B01D53/60
Filed: 1988-06-08
Abstract: An apparatus and method are disclosed for creating high temperature plasmas for enhanced chemical processing of gaseous fluids, toxic chemicals, and the like, at a wide range of pressures, especially at atmospheric and high pressures. The apparatus includes an electro-­magnetic resonator cavity (10), preferably a reentrant cavity and a guiding wave structure (16) which connects an electro-­magnetic radiation source (14) to the cavity. The cavity includes an intake port (26) and an exhaust port (28), each having apertures in the conductive walls of the cavity sufficient for the intake of the gaseous fluids and for the discharge of the processed gaseous fluids. The apertures are sufficiently small to prevent the leakage of the electro-­magnetic radiation from the cavity. A source of gaseous fluid flow from the direction of the electro-magnetic radiation source (14) through the guiding wave structure (16) and into the cavity (10) acts on the plasma to push it away from the guiding wave structure and the electro-magnetic radiation source. The gaseous fluid flow confines the high temperature plasma inside the cavity and allows complete chemical processing of the gaseous fluids at a wide range of pressures.

Abstract: In a device (1) for the detachable connection of a clamping piston (8) of a power-operated chuck (1) to a controlling member (31) designed as a draw rod, the latter is provided with a coupling member (41) which is held axially in a positive-locking manner and is radially displaceable by means of an adjusting member (14) via key mechanisms (50, 53 or 54, 54'; 57, 57'). In addition, the clamping piston (8) and the coupling member (41) have one or more undercut portions (27, 27'; 44, 44'; 28, 28'; 45, 45') having bearing surfaces (29, 29', 29"; 46, 46', 46"), running perpendicularly to the axis, for transmitting the controlling forces, and the undercut portions can be coupled to one another and detached from one another by radial displacements of the coupling member (41). This design enables the connection between the clamping piston (8) and the controlling member (31) to be made and released in a positive manner. Furthermore, the high tensile and compressive forces are transmitted from the controlling member (31) to the clamping piston (8) via surfaces perpendicular to the axis, so that no radially directed force components and thus no deformations and no high friction forces caused thereby occur. <IMAGE>

Abstract: A tissue plasminogen activator (t-PA) derivative has an amino-acid sequence which corresponds to that of natural t-PA but in which the amino acids of the kringle II domain are absent. To produce a t-PA derivative of this type, those sequences of the t-PA DNA which code for the amino acids which are absent from the derivative by comparison with the complete t-PA protein are deleted, the remaining DNA sequences are joined by ligation, they are introduced into an expression vector and expressed in suitable host cells. An agent for dissolving clots contains a tissue plasminogen activator (t-PA) derivative which has an amino-acid sequence which corresponds to that of natural t-PA but in which at least the amino acids of the kringle II domain are absent. <IMAGE>

Abstract: A diffractive bifocal eye lens, an optical system, and processes for fabrication of such lenses are disclosed. The optical system includes the following principal elements in optical alignment along an optical axis (10), for accomplishing the indicated steps of the process: a laser (12) for emission of ultraviolet light along the optical axis (10); a zone plate mask (18) in the path of irradiation by the laser; and an imaging lens (20) to project, with radiation from the laser (12), an image of the mask on the concave inner surface (30) of an eye lens mounted coincident with the image surface of the optical system, thereby ablating the eye lens imagewise of the mask to generate a phase zone plate on the eye lens. The laser beam scans the zone plate mask (18) to generate a composite image on the image surface. Alternatively, the phase zone plate (18) is generated on the concave surface of a glass blank at the image surface to form a tool from which molds, and in turn lenses, are replicated. The light source is an argon fluoride excimer laser (12), emitting at 193 nm. The lens is a variable magnification lens to project various size images of the mask for producing zone plates of various powers as desired.

Abstract: An improved valve assembly is provided for the distal end of a catheter (12), and particularly a central venous catheter for controlling fluid passage from the catheter to the blood flow passage in which it is inserted, and flow in the opposite direction. A relatively thin sheath wall (14) covers the distal fluid opening (25) of the catheter, and includes a slit (16) for responding rapidly to pressure differentials on either side of the slit opening to allow fluid passage, as required. In addition, the distal end of the catheter, and the side walls thereof adjacent the end, are covered by a thin sheath which serves to impart a small degree of thickness or "body" to the end of the catheter except at the opening thereof. More importantly, with the arrangement here the integrity of the catheter wall is far less compromised.

Abstract: A coffee brewing unit is disclosed which enables a brew cycle to be initiated automatically upon insertion of a coffee receiving vessel (40) into its coffee receiving position, but which prevents a brew cycle from proceeding if a number of required operating conditions are not implemented. If all operating conditions again become implemented after a brew cycle, once underway, is interrupted, the brew cycle continues on to completion. Visual signals indicate that a brew cycle is in progress and also when sufficient mineral deposits are present that cleaning of the unit is recommended. An insulated carafe (40) is used as the vessel to receive brewed coffee thereby eliminating the need for a warmer plate. The unit may be mounted under a cabinet to thereby maximize usable countertop space and a coffee basket (30) for the unit utilizes a dispensing valve (86) which is opened by the carafe (40) when inserted into position but which closed when the carafe (40) is withdrawn. Temperature sensitive switch (98) which is used in association with the hot water generator (62) for the unit has a manual reset switch which is actuated by a self-contained water reservoir (24) when moved into its operating position.
