Filed: 1991-02-21
Abstract: Ce moteur générateur de pression de gaz possède un piston totalement libre (33) se déplaçant entre une chambre d'explosion (49) et un volume de rebondissement (37). Le piston (33) découvre un orifice de sortie (22) après avoir parcouru une petite distance à partir de la chambre d'explosion (49) et utilise le reste de la longue course du piston pour aspirer de l'air nouveau; après quoi, en se dirigeant de nouveau vers la chambre d'explosion (49), il pompe vers la sortie (22) une grande partie de l'air aspiré. Le restant de l'air aspiré est comprimé davantage pour la combustion. La course du piston (33) n'est restreinte que par l'énergie qu'il reçoit de la chambre d'explosion (49). La pression du volume de rebondissement est réglable pour permettre d'ajuster le rapport pression-volume du gaz de sortie. Une soupape réglée (21) située dans la sortie (22) et un tuyau de pression de fermeture réglé (23) maximisent le balayage de la chambre d'explosion (49) par les gaz, améliorant ainsi l'efficacité du moteur tout en étendant sa plage de fonctionnement.

Patent EP-0638087-A4 (EP)
Title: Modified nucleotides.
Inventor: HACES ALBERTO
IPC: C07H19/20
Filed: 1993-03-17
Abstract: The present invention provides novel modified nucleotide compounds having the general formula: X-n(J)-(d or r)NTP where N is adenosine, guanosine or cytidine; X is H, a fluorophore, a chromophore, a luminescent compound, a ligand or a hapten; n is an integer of 7 or more; and J is a Jeffamine (TM Texaco, Inc.) substituent. These compounds are substantially superior substrates for incorporating label into nucleic acids during enzyme-catalyzed synthesis. Use of a Jeffamine-linked labelled nucleotide derivative as a partial substitute for unlabelled substrate therefore leads to significantly greater incorporation, hence increased label density per unit length of nucleic acid, than the same label joined by a prior art linker. Jeffamine-modified ribo- or deoxyribo-nucleotides are also provided for synthesis of Jeffamine-modified nucleic acids. The invention further provides an improved method of synthesizing labelled nucleic acids. This method provides greater frequency and higher efficiency of label incorporation, thus requiring lower amounts of nucleotide derivative in the reaction mixture.

Patent EP-0688364-A4 (EP)
Title: Genetically engineered enzymes and their conjugates for diagnostic assays
Inventor: BRATE ELAINE M
IPC: C12N15/55
Filed: 1994-03-09
Abstract: This invention relates to genetically engineered enzymes, their ligand conjugates, their manufacture, and their use in qualitative or quantitative assays. A hybrid enzyme, such as an AP-epitope, has a foreign amino acid moiety (an epitope) inserted near the active site of the starting AP enzyme. The foreign amino acid moiety binds with an analyte, and, as a consequence of this binding, the enzymatic activity of the hybrid enzyme, AP-epitope, is modified. The changes in the enzymatic activity are dependent upon the presence, or the amount, of the analyte. In another embodiment, the hybrid enzyme consists of a cysteine introduced near the active site of an AP to give a hybrid enzyme. The cysteine on the hybrid enzyme serves as a point of conjugation of a ligand, such as theophylline, ferritin, thyroxine, or digoxigenin, to form the hybrid enzyme-ligand conjugate. The ligand binds with an antibody, an analyte or a binding molecule to an analyte and as a result of this binding, the enzymatic activity of the hybrid enzyme-ligand conjugate is modified or modulated.

Title: Heat transfer apparatus with positive drive orbital whip rod
Inventor: LI YAO-TZU
IPC: F25C1/14
Filed: 1994-06-16
Abstract: A heat transfer apparatus for processing a liquid continuously has a positive mechanical drive for a set of vertical whip rods each disposed in a vertical heat transfer tube. Each whip rod is free-standing on its lower end and is sufficiently flexible to conform closely to the inner surface of the tube as it orbits. The orbital drive propels the whip rod directly through a pair of horizontal, vertically spaced plates that engage the rods in loose openings that serve as fluid inlets from the drive plate. A motor rotates a drive shaft coupled to at least one of the drive plates through at least one eccentric crank. Each plate can be an opposed pair of plates with a separate eccentric drives 180 DEG  out of phase with one another for a self balancing. Another form of drive plate uses a rigid circular ring that mounts rod-engaging sleeves via a network of wires supported by the ring. Fluid distribution can also be from a water supply held between a fixed plate and the upper drive plate with gravity feed to each tube through a properly sized inlet opening in the upper tube end. To isolate the heat transfer process, various seals are used to transmit rotary power through a housing without conventional rotary seals.

Patent EP-0871415-A4 (EP)
Title: Heart valve replacement using flexible tubes
Inventor: COX JAMES L
IPC: A61L27/36
Filed: 1995-12-28
Abstract: This invention comprises a method of using tubular material (200) to replace a heart valve (118)(120)(162) during cardiac surgery. To create a replacement atrioventricular (mitral or tricuspid) valve (120)(160), the tube inlet is sutured to a valve annulus (121)(162) from which the native leaflets have been removed, and the tube outlet is sutured to papillary muscles (126)(128)(170) in the ventricle (112)(152). To create a semilunar (aortic or pulmonary) valve (118), the tube inlet is sutured to an annulus from which the native cusps have been removed, and the tube is either "tacked" at three points distally inside the artery, or sutured longitudinally along three lines; this allows the flaps of tissue between the three fixation points at the valve outlet to function as movable cusps. These approaches generate flow patterns that closely duplicate the flow patterns of native valves. A preferred tubular material (200) comprises submucosal tissue from the small intestine; this can be taken from the same patient who is undergoing the cardiac operation, to reduce antigenicity. Animal or cadaver intestinal tissue can also be used if properly treated, or a biocompatible synthetic tubular material can be used. This invention also discloses a properly treated intestinal tissue segment or synthetic tubular segment (500) suitable for implantation as a replacement heart valve, enclosed in a sealed sterile package (510). <IMAGE>
