Title: A novel method for the integration of foreign DNA into eukaryoticgenomes
Inventor: BASZCZYNSKI CHRISTOPHER L
IPC: C12N15/82
Filed: 1998-11-17
Granted: 2003-09-18
Abstract: Compositions and methods for introducing a DNA of interest into a genomic target site are provided. In particular, the methods and compositions involve the use of a combination of target sites for two site specific recombinases and expression of a chimeric recombinase with dual target site specificity. Thus, the compositions comprise novel site-specific recombinases with specificities to multiple target sites, and nucleotide sequences and expression cassettes encoding these recombinases or target sites. The methods involve transforming a eukaryotic cell having target sites for the novel recombinase with a DNA of interest that is flanked by corresponding target sites. Expression of the recombinase results in integration of the DNA of interest into the genome of the cell. The compositions and methods of the invention have use in the construction of stably transformed eukaryotic cells, and in particular, plant cells. The methods result in the efficient targeted genomic integration of DNA by site-specific recombination.

Title: Method of making laminated ptfe-containing composites and products thereof
Inventor: EFFENBERGER JOHN A
IPC: B32B7/04
Filed: 1990-02-28
Granted: 1994-06-21
Abstract: Dispersion polymerized PTFE itself, if provided in an unfused state, is sufficiently capable of acting as a pressure sensitive adhesive to facilitate the formation of an initial mechanical bond between components of a laminate such that it may be subsequently heat treated in a rela-tively short period of time to produce a well-bonded final laminate.  This fact makes it possible to prepare a laminate comprising at least one layer containing PTFE by the steps of:               (a)  preparing a first dimensionally stable laminate component having two major surfaces, at least one of said major surfaces having an exposed layer comprising unfused PTFE;               (b)  preparing a second dimensionally stable laminate component having two major surfaces, at least a first of said major surfaces being capable of forming an integral bond with the unfused PTFE-containing layer;               (c)  bringing said first and second laminate components together so that the exposed layer comprising unfused PTFE and the surface bondable with the unfused PTFE-containing layer are in contact with each other;               (d)  applying pressure to the combined lami-nate components at moderate temperature to achieve intimate contact and form a mechanical bond between the first and second laminate components;               (e)  introducing the mechanically bonded to a heating zone under conditions which avoid delamination; and (f)  sintering the mechanically bonded lami-nate components in a heating zone to consolidate the unfused PTFE-containing layer.  The mechanical bond formed is suffi-ciently strong that the consolidation can be done in a free-sintering process (no applied pressure).  Application of pressure, however, is generally not detrimental to the product.

Granted: 1995-06-27
Abstract: An improved method is provided herein for sheathing a defined length of a pitched cable with a layer of plastic.          In the improved method, the outside diameter of the defined length of cable is first reduced to a smaller diameter, and a plastic pipe is drawn onto this length of reduced diam-eter.  Then, by applying an external force to reduce the outside diameter of this plastic pipe, the pipe is fixed in such a way on the pitched cable that at least part of the inner wall of the plastic pipe protrudes into the space between the turns in the pitch elements.   The outside diameter of the defined length of the pitch elements may be reduced by grinding the outside diameter smoothly down or by hammering or rolling so that, as a result of this reduc-tion in diameter, no compaction occurs in the material of which the pitch helix or carrier cable is made.

Title: Dc braking of inverter-driven ac motors
Inventor: GRITTER DAVID J
IPC: H02P3/24
Filed: 1990-10-05
Granted: 1996-05-07
Abstract: A DC braking system for an inverter-driven induction motor, (e.g., three-phase).  When a braking command occurs, the normal gating sequence of the inverter stops.  Mode 1 of the braking procedure starts.     In Mode 1, two semiconductor phase switches of the group connected with one of the DC buses and the semiconductor switch of the third phase that is connected with the other DC bus are latched in a conducting state.  The motor essentially receives DC current, which increases until it actuates a current limit device, clearing the latch. Then all six switches are turned off.  That drives the motor current through the back-biased parallel diodes.  The negative DC bus voltage is available to suppress motor current despite large motor speed voltages.  The apparatus repeats the Mode 1 procedure for a predetermined time interval, after which Mode 2 of the braking procedure starts.     In Mode 2, just as in Mode 1, two switches of one bus and one switch of another bus conduct until an overcurrent limit is reached.  Then the one switch which is connected to a different bus turns off and its complement (same phase, other bus) turns on, allowing motor current to circulate in the motor windings.  This allows current to decay at a slower rate than it would in Mode 1.  The procedure of Mode 2 is repeated for a predetermined time interval.     If the motor speed is below a predetermined threshold when the braking command occurs, Mode 1 is skipped and only Mode 2 is used.

Abstract: Disclosed is a glass body suitable for cementing to a further material. At the time of cementing, there is at least one profile of a cement on the glass body, and it is already solidified at the time of cementing and serves as a range spacer. Furthermore, there is a profile of a second cement on the glass body which ce-ment is still moldable and has adhesive characteristics at the time of cementing. when producing the adhesive connection, the second cement is formed and pressed against the other material. Because the profile of the second, still adhesive cement is directly on the glass body or possibly a layer of a material impermeable to ultraviolet or, where necessary, an intermediate layer of primer, a very good adhesion can be achieved.

Title: Method & apparatus for measuring oxygen concentration and its subsequent use in estimating nitrogen fixation in plants
Inventor: LAYZELL DAVID B
IPC: G01N21/25
Filed: 1991-03-18
Granted: 2001-02-13
Abstract: A non-invasive method and apparatus are described for measuring the oxygen concentration in the infected cells of the nodules of nitrogen fixing plants in the laboratory or field. In many cases, this information can be used to estimate the nitrogenase activity, and therefore the nitrogen fixation rate, in these nodules since recent studies have shown that the oxygen concentration limits and controls nitrogenase activity under most environmental conditions. Using the same apparatus, a method to measure nodule respiration and nodule oxygen permeability is also described. The nodule oxygen concentration in the infected cells of nodules is maintained at very low levels and has not been measurable previously by non-invasive techniques.      The fractional oxygenation of plant hemoglobin is measured spectroscopically using one or more modulated light sources, a number of optical fibres to convey the light to and from the nodules, a photodetector to measure the light passing through the nodule and a detection system such as a photodiode coupled to a microcomputer or a lock-in amplifier to process the output signal.

Granted: 1995-09-19
Abstract: A dual channel helical scan recording system (30) includes a rotating drum (36) having sets of heads (W1, W2, R1, R2) mounted on its peripheral surface (56). A set of write heads (W1, W2) is situated on an opposite side of the drum (36) from a set of read heads (R1, R2). The write heads (W1, W2) simultaneously write two adjacent tracks (T1, T2), which are read for verifica-tion 180 degrees later by corresponding read heads (R1, R2). The heads (W1, W2, R1, R2) are strategically mounted on the drum (36) with respect to angular and axial placement, and have selected head widths and azimuthal angles. Should a block of data (317) written to tape (32) be determined, during readback, to be a bad block, that bad block is subsequently rewritten on the tape (32) in the course of writing good blocks and amongst other good blocks. The rewritten block is recorded at a row position on the tape which is sufficiently displaced from the row position of a previous writing to avoid media defects occurring on the tape. In addition, a block written by a first write head (W1) and perceived as having been written as a bad block must be written by a sec-ond write head (W2) before that block is rewritten a predetermined number of times.
