Abstract: A pump with a continuous inflow and a pulsating outflow comprises a first chamber and a second chamber with a passage between them and made from a flexible material, provided with an inlet to the first chamber and an outlet from the second chamber, the passage between the chambers being provided with a one-way valve permitting flow in direction from the first to the second chamber only, and a second one-way valve arranged at the outlet permitting flow out of the second chamber only. The chambers are movably supported in a pump casing with a first and a second opening, in that the inlet is connected to and penetrates the first opening, and in that the outlet is connected to and penetrates the second opening. Drive means cyclically affect the second chamber and reduce its volume under expulsion of the medium which is pumped while simultaneously affecting the walls of the first chamber causing its volume to increase and medium to flow through the inlet into the chamber. The drive means include a drivering surrounding said passage and fixed to it, and which drivering has surfaces engagable with the first and the second chamber walls in a way that the medium taken in between periods when the drive means is affecting the chamber walls controls the output of the pump by defining the receding movement of the drive ring, which movement is a function of the differential pressure force resulting from the difference in areas of engagement with the respective chamber wall on both sides of the drive ring.

Title: Preparation and use of gene banks of synthetic human antibodies ("synthetic human-antibody libraries")
Inventor: LITTLE MELVYN
IPC: C12N15/13
Filed: 1991-01-31
Granted: 2003-07-08
Abstract: The invention relates to the preparation and use of gene banks of synthetic human antibodies (huAb) or parts of antibodies which contain the antigen-binding domain.      Starting from a huAb framework in a suitable vector, the hypervariable regions of the antibody cDNA are formed by almost "randomly" combined oligonucleotides. Relatively conserved amino acids in the hypervariable regions have here been taken account of in the choice of appropriate nucleotides during the oligonucleotide synthesis and the ratio of the nucleotides used is likewise chosen such that a nonsense codon is to be expected at most in every 89th position. Expression of this synthetic huAb cDNA in microbial expression systems, e.g. in E, coli in the vector pFMT which is described below, thus makes a synthetic huAb library with a comprehensive repertoire for screening using selected antigens available in vitro.

Title: Piezoelectric differential pressure vortex sensor
Inventor: KALINOSKI RICHARD W
IPC: G01F1/32
Filed: 1990-12-19
Granted: 2002-01-22
Abstract: A vortex sensor for measuring a flow rate of a fluid flowing through a flow passage is disclosed. The flow rate is measured by detecting alternating pressure variations generated by a shedding body placed in the flow passage. The vortex sensor includes a sensor housing having two cavities interconnected by a channel. An axle of a spool member is slideably disposed in the channel and allows each of two flange members, connected proximate each end of the axle, to shuttle back and forth with respect to the sensor housing. A piezoelectric sensing element and a biasing mechanism are disposed between the flange members and the sensor housing. The alternating pressure variations are applied to each flange member causing the spool member to shuttle back and forth. When the spool moves, mechanical forces are coupled to each sensing element by the biasing mechanisms. Circuitry, interconnected to the sensing elements, detects signals generated by the sensing elements as a result of forces applied to them.

Title: Medical and dental treatments using laser radiation
Inventor: LEVY GUY C
IPC: A61B17/00
Filed: 1991-11-14
Granted: 1999-04-20
Abstract: The cutting of tooth or bone tissue with laser radiation  is  enhanced  by  giving  the  radiation  a polarization P parallel to the surface of the tissue being cut. For enlarging a tooth canal, laser radiation is delivered via an optical fiber which is introduced into the canal and is tapered in the region of its distal end. To fill a canal, an optical fiber having a low melting point is introduced into the canal and radiation is conducted through the fiber to melt the fiber and form the filling. The fiber may be coated with a material which will be melted by the radiation and will bond to the canal wall. Fillings and coatings are formed on tooth or bone tissue by projecting toward a surface of the tissue two starting components which when combined and exposed to light of a selected wavelength undergo a photochemical  reaction to  form a calcium containing product, and causing light of the selected wavelength to impinge on the components at least partially before they reach the surface in order to create the reaction and cause the resulting calcium containing product to bond to the tissue. Bacteria on a tooth surface are destroyed by staining the bacteria to cause the bacteria to have a dark coloration, and exposing the stained bacteria to laser  radiation  at  a  wavelength  and  energy  level sufficient to destroy the bacteria.
