Inventor: WITTENBRINK ROBERT JAY
IPC: C10G2/00
Filed: 1996-11-15
Abstract: Discloses high purity solvent compositions constituted of n-paraffins and isoparaffins, with the isoparaffins containing predominantly methyl branches, and having an isoparaffin:n-paraffin ratio sufficient to provide superior low temperature properties and low viscosities. The solvent compositions are made by a process wherein a waxy, or long chain paraffinic feed, especially a Fischer-Tropsch wax, is reacted over a dual function catalyst to produce hydroisomerization and hydrocracking reactions at 700 °Ft conversion levels ranging from about 20 to 90 wt.% to provide a C5-1050 °F crude fraction. The C5-1050 °F crude fraction is then topped via atmospheric distillation to produce a low boiling fraction with an upper end point boiling between about 650 °F and 750 °F. The low boiling fraction is fractionated and a narrow boiling range solvent obtained therefrom; one which can be further divided into solvent grades of various boiling ranges.

Title: Single chamber blood pump
Inventor: PREM EDWARD KARL
IPC: A61M60/876
Filed: 1998-12-17
Abstract: A blood pump apparatus can include a pump housing having a drive chamber containing a drive mechanism. A cupped member can be connected to the housing and the drive mechanism can include a motor for rotating an eccentric shaft. A  pumping arm can be provided having one end riding on the eccentric shaft, an intermediate portion pivotably attached to the housing and another end connected to a movable plate. A roller bearing can be mounted on the eccentric shaft on which the arm can ride. A compressible blood chamber having an inlet and an outlet connected can be provided sandwiched between the cupped portion and the movable plate. The motor thus rotates the cam causing the pumping arm to pivot which cycles the movable plate against the blood chamber to pump blood. The movable plate can be implanted adjacent a lung such that the lung moves with the plate as blood is pumped and thereby functions as a compliance chamber. A speed reducer can be provided between the motor and the eccentric shaft. A hermetically sealing bellows can be provided to seal the drive chamber and the end of the pumping arm from body fluids. An enclosure bag can be provided surrounding all or a portion of the blood pump to provide a tissue friendly surface and to prevent tissue from becoming caught in the moving parts of the blood pump. A position sensor can be included for determining a volume of blood in the chamber for use by an electronic controller to control the speed of the motor to optimize pumping action.

Abstract: L'invention concerne un sac en plastique doté d'une fermeture et comprenant un premier et un deuxième panneau, les deux panneaux étant opposés et fixés l'un à l'autre le long de deux côtés, et un fond reliant les deux côtés. Le sac comprend une fermeture à glissière (22) refermable s'étendant le long d'une ouverture située à l'opposé du fond (20) soudé. La fermeture à glissière comprend une bande mâle à profil mâle et une bande femelle à profil femelle.

Title: System and method for subscriber controlled signal blocking
Inventor: HAUSER AVI I
IPC: H04N7/16
Filed: 1999-03-25
Abstract: A technique for the blocking of individual programs and/or portions of programs transmitted in a source signal, e.g., a cable television signal. In particular, individual programs and/or portions of programs within a class of programs are blocked, while allowing for the viewing of certain other programs even within the same programming class. The transmitted source signal contains individual programs having a transparent program identifier and/or transparent content identifier associated with individual programs in the source signal transmission. As the source signal enters, e.g., a particular subscriber location, the source signal is monitored in accordance with a program viewing profile defined by the subscriber. That is, particular ones of the programs and/or portion thereof available in the source signal transmission supplied to the subscriber can either be unblocked, i.e., viewable, or blocked, i.e., unviewable, at the discretion of the subscriber. The blocking of particular ones of the programs and/or portion thereof is accomplished as a function of the transparent program identifier and/or transparent content identifier associated with a program which is embedded in the video and/or audio component of the source signal. The transparent identifiers are transmitted concurrently with the individual program as the source signal is received at the subscriber location.  Advantageously, the subscriber is given complete control and selectivity over which programs and/or portions thereof are viewed, e.g., by children of the subscriber.
