Title: Circular extension for generating multiple nucleic acid complements
Inventor: RUTH JERRY L
IPC: C12Q1/68
Filed: 1991-07-17
Abstract: A process for generating multiple linear complements of a single strand, circular nucleic acid template containing at least one cleavage site is described. The process consists of combining the single strand, circular nucleic acid template with polynucleotide primers under conditions sufficient for hybridization; extending the polynucleotide primer more than once around the circle to generate a complementary displacement of more than one contiguous complement of the single strand, circular nucleic acid template.  Also described is a process of synthesizing novel single strand, circular nucleic acids between 30 and 2200 nucleotides. The process consists of synthesizing a linear polynucleotide; combining the linear polynucleotide with a complementary linking oligonucleotide under conditions sufficient for hybridization; and ligating the linear polynucleotide to produce a single strand, circular nucleic acid.
Patent CA-2088204-A1 (CA)
Title: Non-mechanical tank
Inventor: ISMAIL SOOLIMAN
IPC: C22B11/08
Filed: 1993-01-27
Abstract: ABSTRACT This invention relates to the treatment of a liquid/solid slurry. More particularly, a method of treating such a slurry in a tank comprises introducing a first gas into the slurry to agitate the slurry and prevent settling of solids in the tank.  A second gas is introduced separately into the slurry to effect a solution of the second gas in the slurry.  Separation means are provided in the tank so that the agitation of the slurry by the first gas and the dissolution of the second gas in the slurry are effected in the separate regions or zones of the tank so that contact between the first and second gases is minimized.  These gases may be air and oxygen, respectively.

Title: Design of bioactive peptides based on immunoglobulin structure
Inventor: WILLIAMS WILLIAM
IPC: C12N15/13
Filed: 1991-09-13
Abstract: The present invention relates to a method for producing peptides which have biological activity comprising: (i) identifying a region of a protein of interest which is homologous to a member of the immunoglobulin superfamily of molecules; (ii) synthesizing a peptide which comprises amino acid sequence found in the region of homology; and (iii) modifying the synthetic peptide such that it assumes a three-dimensional conformation which is biologically active. The invention is based, in part, on the discovery that a cyclic peptide comprising amino acid sequences of a CDR derived from an antibody directed toward a viral receptor molecule can be used to effectively inhibit the binding of virus to its receptor.  The invention is also based in part on the discovery that a cylic peptide corresponding to a portion of human immunodeficiency virus (HIV) gp120 that is homologous to immunoglobulins may be used to generate an anti-HIV immune response.

Title: Device for cutting a paper web in a press end of a paper machine
Inventor: RUF GUENTHER
IPC: D21F7/00
Filed: 1993-05-20
Abstract: A cutting-off device and at least one tear detector are provided for cutting a web of paper in a press end of a paper machine, in response to a tear in the web of paper in a single-tier dryer and, the tear of the web of paper being recognized via a tear signal and transmitted to the cutting-off device. The tear detector has a transmission/reception base unit, which, on the one hand, at the start of a production cycle, or whenever a tear in the paper web is detected, records and stores the spectrum of the existing shade of color of the corresponding dryer felt, and possibly updates the stored shade of color at the time of subsequent tears. On the other hand, upon a later tear in the paper web, the base unit compares the shade of color of the dryer felt at the existing tear and the previously stored shade of color.      If they match, the base unit activates the cutting-off device When (and only when) the stored shade of color of the dryer felt is recognized.

Patent CA-2109234-A1 (CA)
Inventor: FROLA FRANK R
IPC: G01F1/66
Filed: 1993-10-26
Abstract: A gas concentration and/or bulk flow rate sensor suitable for measuring the oxygen concentration and the bulk flow rate of gas delivered to a patient for medical purposes. Two piezoelectric transducers mounted on a printed circuit board are interconnected by an elongated coiled tube. The gas is flowed around one of the transducers, through the tube and around the other transducer. Periodically, one of the transducers is energized with a single short duration pulse to transmit a sonic wave through the gas to the other transducer. The travel time for the sonic wave is measured. The two transducers are alternately used as transmitters and receivers so that the wave travel time is measured both with and against the gas flow direction. A thermistor is located in the center of the coiled tube for measuring the temperature of the gas. From the measured times, the measured temperature and stored formulas, a microprocessor calculates the oxygen concentration and/or the bulk flow rate for the gas. The sensor also may be used to measure other components of a gas mixture.

Title: Method and apparatus for multivariate characterization of optical instrument response
Inventor: RUHL HARRY D JR
IPC: G01J3/28
Filed: 1992-08-06
Abstract: The system consists of light source (2), a monochrometer (4), one or more etalons or other samples (7), a detector (8) and a computer (10) to store reference spectra, provide a read out indicative of the spectrum and to change the instrument response. A  transfer function is used to recharacterize the instrument's wavelength position and intensity response to match the actual spectrum with the standard spectrum. In one embodiment, the etalon (7) is used in series with the unknown sample (9). A spectrum of the unknown sample and etalon (7) is created and is extracted from the spectrum of the unknown sample (9) alone to provide the actual spectrum of the instrument response to the etalon (7) alone. The actual spectrum can then be compared to the standard spectrum and the instrument response recharacterized accordingly.
