Title: Method and apparatus for parametric generation of midinfrared light in knbo3
Inventor: GUYER DEAN R
IPC: G02F1/39
Filed: 1991-11-19
Abstract: METHOD AND APPARATUS FOR PARAMETRIC GENERATION OF MID-INFRARED LIGHT IN KNbO3 Abstract of the Disclosure A method and apparatus for parametric conversion of electromagnetic radiation in KNbO3 crystals of optical energy at a wavelength near 1 µm to optical energy at wavelengths in the range from 1.4 µm to 4.6 µm.  A pump beam and a signal beam impinge on a KNbO3 crystal and interact to produce optical energy at an idler wavelength and a signal wavelength at the expense of optical energy of the impinging j       pump beam wavelength. The KNbO3 crystal has an orientation axis which is aligned with the direction of the impinging pump and signal energy and is on a locus defined by a minimum phase relation between the energy at the pump, signal, and idler frequencies.

Abstract: PHA 21.650                                   14-10-1991 Abstract of the Disclosure A rectifier bridge includes two pairs of diodes , each pair connected to opposing ends of the secondary winding of a boost transformer whose primary winding is in series with the secondary winding of a high frequency DC/AC inverter circuit output transformer which is connected to ballasting capacitors in a fluorescent lamp receiving circuit. The bridge output charges a smoothing DC supply capacitor whose voltage is boosted by a pair of capacitors charged by the boost transformer whose inductance determines that the zero portion of the incoming line current waveform is boosted. The line voltage peaks are uncorrected.  In a second embodiment both the peak region and the zero crossing region of the incoming line current waveform are corrected by deriving a portion of the boost voltage from the load circuit and a portion from the inverter circuit.

Title: Protein partner screening assays and uses thereof
Inventor: KINGSON ROBERT E
IPC: C12N15/10
Filed: 1991-03-26
Abstract: A rapid, simple and inexpensive method to screen and classify proteins as partners of heterodimeric proteins is described which utilizes fusion protein constructs containing a DNA binding domain and a dimerization domain from a different protein. According to the method of the invention, heterodimer formation is detected by the ability of the protein partner to displace homodimer formation, and thus reveal a phenotypic change in a bacterial host which was dependent upon maintenance of the homodimer configuration.  The method of the invention may be used to identify compounds of interest which inhibit such heterodimer formation, and especially to identify compounds which prevent heterodimer formation and activation of oncogenic transcriptional regulatory proteins.
Patent CA-2078863-A1 (CA)
Inventor: URDEA MICHAEL
IPC: C12Q1/68
Filed: 1991-03-22
Abstract: An analyte polynucleotide strand having an analyte sequence is detected within a sample containing polynucleotides by contacting the analyte polynucleotide with a capture probe under hybridization conditions, where the capture probe has a first binding partner specific for a solid-phase second binding partner. The resulting duplex is then immobilized by specific binding between the binding partners, and non-bound polynucleotides are separated from the bound species. The analyte polynucleotide is optionally displaced from the solid phase, then amplified by PCR. The PCR primers each have a polynucleotide region capable of hybridizing to a region of the analyte polynucleotide, and at least one of the primers further has an additional binding partner capable of binding a solid-phase binding partner. The amplified product is then separated from the reaction mixture by specific binding between the binding partners, and the amplified product is detected.

Title: Gating means for metal matrix composite manufacture
Inventor: LANGENSIEPEN RALPH A
IPC: C04B41/88
Filed: 1991-05-09
Abstract: The present invention relates to the use of a gating means (3) in combination with a spontaneous infiltration process to produce a metal matrix composite body. Particularly, a permeable mass of filler material or a preform (2) is spontaneously infiltrated by molten matrix metal (5) to form a metal matrix composite body. A  gating means (3) is provided which controls or limits the areal contact between molten matrix metal (5) and the filler material or preform (2). The use of a gating means (3) provides for control of the amount of matrix metal (5) which can contact the preform (2) or filler material, which may result in less machining of a formed metal matrix composite body compared with a similar metal matrix composite body made without a gating means (3). Moreover, the use of a gating means (3) ameliorates the tendency of a formed metal matrix composite body to warp due to the contact between the formed composite body and matrix metal carcass.
