Title: Pipe Bending Machine
Inventor: HEAMAN NORMAN LAVERNE
IPC: B21D11/00
Filed: 1995-09-18
Abstract: A pipe bending machine is described which utilizes a cord and lattice support structure having a first end, a second end, an interior lattice framework and an exterior connecting cord which connects the periphery of the interior lattice framework.  Pipe securing tie backs are secured to the support structure adjacent each of the first end and the second end. At least one pressure exerting hydraulic cylinder is secured to the support structure intermediate the first end and the second end.   The hydraulic cylinder has a pressure member movable in relation to the support structure thereby exerting a bending force upon a pipe held by the pipe securing means. The bending force places the interior lattice framework in compression and the connecting cord in tension.  The forces of compression and tension being off-setting thereby enabling the support structure to withstand the bending force.  The cord and lattice support structure, as described, enables the pipe bending machine to be made light enough to be carried by one man to remote locations along a pipeline right of way or other such construction sites.

Patent CA-2177087-A1 (CA)
Inventor: NETUPSKY BORIS
IPC: E01D15/14
Filed: 1996-05-22
Abstract: This invention comprises the use of the force of buoyancy to counter the gravity forces due to the dead and live loads imposed on bridge structures spanning bodies of water.   This is achieved by securing to the underside of the bottom chord or element of the bridge superstructure, restrained at each end from vertical movement, a buoyancy block or a plurality of buoyancy blocks submerged at all levels of the body of water, thus providing the desired prestress to the superstructure to counter the gravity loads. Further, in a trussed type of superstructure, buoyancy collars may be secured to the vertical elements of the truss, providing additional prestressing forces when the body of water rises and a resistance to the deflection of the bridge structure from the live loads, thus reducing the shearing forces, bending moments, and reactions at the two ends or abutments of the bridge.

Title: Identification of nucleotides, amino acids, or carbohydrates by mass spectrometry
Inventor: YATES JOHN R III
IPC: C12Q1/6816
Filed: 1995-03-14
Abstract: A method for correlating a peptide fragment mass spectrum with amino acid sequences derived from a database is provided. A peptide is analyzed by a tandem mass spectrometer to yield a peptide fragment mass spectrum. A protein sequence database or a nucleotide sequence database is used to predict one or more fragment spectra for comparison with the experimentally-derived fragment spectrum. In one embodiment, sub-sequences of the sequences found on the database which define a peptide having a mass substantially equal to the mass of the peptide analyzed by the tandem mass spectrometer are identified as candidate sequences. For each candidate sequence, a plurality of fragments of the sequence are identified and the masses and m/z ratios of the fragments are predicted and used to form a predicted mass spectrum. The various predicted mass spectra are compared to the experimentally derived fragment spectrum using a closeness-of-fit measure, preferably calculated with a two-step process, including a calculation of a preliminary score end, for the highest-scoring predicted spectra, calculation of a correlation function.

Filed: 1996-10-21
Abstract: A  method  and  device  for  harvesting  hay  are disclosed.  The method includes injecting steam into hay as it is being processed by a baler. Typically, the hay will be subjected to steam as it is lifted into the baler, and then subjected to steam as it passes through a feed chamber of the baler.  Preferentially, the hay will be saturated with steam less than two seconds before it is formed into a bale of hay.   The device includes a conventional baler having one or more steam manifolds disposed so as to emit steam into the hay between  the  point  it  is  picked  up  by  a  pick-up mechanism,  and the point at which it is ultimately formed into a bale of hay.  By saturating the hay with steam, dew moisturization is simulated and less loss occurs.  However, the moisture content reading in the resulting bale of hay decreases much more rapidly than dew  moistened  hay,  thus  decreasing  spoilage  and increasing the amount which may be sold to the most lucrative markets.  The invention also includes a method for improving the absorption of moisture from the steam which includes cooling the hay prior to application of the steam.
