Granted: 1992-10-27
Abstract: Abstract of the Disclosure A box-like frame member is formed by compressing an internally-pressurized tubular blank within a die having a cavity conforming to the final box-like cross section desired for the product, and increasing the pressure to exceed the yield limit of the wall of the  blank  to  expand  the  blank  into  conformity with  the  die cavity.  The blank is selected so that the final product and the die cavity have a circumference preferably no more than about 5% larger than the circumference of the blank, to avoid weakening or cracking of the blank through excessive circumferential expan-sion.   The internal pressure forces the blank evenly into the corners of the die on closing and allows the blank to be confined within the die without sections of the die pinching the blank on closing of the die.

Title: Apparatus and method for subsurface injection of agrochemicals
Inventor: CROSS HEWIS W
IPC: A01C23/02
Filed: 1988-09-20
Granted: 1991-09-17
Abstract: ABSTRACT    This invention relates to a method and apparatus for injecting agrochemicals into the subsurface of the soil without tilling of the soil.  A high pressure pump delivers the solution to be injected to a series of injection nozzles.  The injection nozzles cause liquid jets to be formed which have sufficient velocity and narrow cross-section to inject into the soil.  The injection nozzles are supported by a shield-pan which rides on the surface of the soil.  The apparatus causes continuous injection from a plurality of nozzles.  The shield-pan minimizes clogging of the nozzles.  In the preferred embodiment, a second low pressure system is incorporated to broadcase spray the soil surface.  This is a low-pressure system utilizing a boom with broadcast nozzles.

Granted: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE        A dual-column, dual-detector gas detector and analyzer employs both a photo-ionization detector and a flame-ionization detector.  In a survey mode, samples of ambient air are driven through both detectors, and the outputs of both detectors are used to determine the presence of one or more gasses.  In analysis mode, fixed-volume samples of ambient air are driven through two elution columns having different properties. The output of each elution column is fed to one of the detectors.  The arrival times is fed to one of the detectors are employed to develop two lists of candidate gasses.  The lists are cross-checked for the presence of each candidate on both lists.  Candidates identified from their presence on both lists are identified.  A further check attempts to identify candidates which are identifiable form their presence on one of the lists, and not on the other.  Components identified in this way are added to the final list.  Unidentified components are discarded, although their presence is noted and reported as unknown.  Portability is retained by eliminating isothermal ovens and by reducing the quantity of hydrogen required.  A simplified way of characterizing temperature corrections of elution columns is disclosed.

Filed: 1989-08-08
Granted: 1999-03-30
Abstract: Methods for isolating thymidine kinase-encoding DNA of a herpes virus are described.  These methods utilize degenerate primers based on regions of relatively conserved amino acid sequence in herpes virus thymidine kinase proteins to initiate a polymerase chain reaction which yields large amounts of the thymidine kinase-encoding DNA.   The methods are illustrated in the isolation of the thymidine kinase gene of feline herpes virus, which can be used to construct recombinant thymidine kinase-negative feline herpes viruses for purposes of constructing live vaccines and expression vectors.  In addition, the regulatory elements of the feline herpes virus thymidine kinase gene are useful in the construction of recombinant DNA vectors.
