Patent CA-2154820-A1 (CA)
Title: Rotary ultrasonic apparatus and methods
Inventor: RAJALA GREGORY JOHN
IPC: B29C65/00
Filed: 1995-07-27
Abstract: This invention pertains to methods and apparatus for processing workpieces, including effecting changes in the workpieces by applying ultrasonic energy to the workpieces using novel apparatus and steps for applying the ultrasonic energy to the workpieces. Specifically, an ultrasonic horn and anvil are used to apply ultrasonic energy in a limited amount, to effect change such as cutting in one layer of a workpiece without effecting a corresponding change in the other layers of the workpiece, although some change in the other layers may be tolerated and/or desired. A rotary horn and anvil are taught, with a protuberance on either the horn or the anvil. In use, the horn and anvil preferably rotate cooperatively in close proximity to each other at a nip, and apply pressure and corresponding ultrasonic energy to the workpiece only when the protuberance rotates into the nip, even though ultrasonic energy may be applied uniformly to the ultrasonic horn throughout the rotation of the protuberance. The workpieces may be presented to the horn/anvil combination as contained serially in a web of workpieces passing through the gap at a given speed; the speed of the protuberance being preferably substantially matched to the speed of the web while the protuberance is applying ultrasonic energy to a workpiece, but may differ from the speed of the web when the protuberance is not applying ultrasonic energy to a workpiece.

Title: Method and apparatus for determining material fatigue by measuring damping factors
Inventor: DIMAROGONAS ANDREW D
IPC: G01N3/06
Filed: 1994-03-01
Abstract: The fatigue integrity of metallic ma-terials may be determined be either one of two methods. In a first method, an impulse of energy is introduced into the metallic ma-terial, such as by striking the metallic mate-rial (20), and the induced vibration is sensed and analyzed in order to compute the damp-ing factor thereof, the damping factor be-ing directly related to the fatigue thereof. With this method, a transducer (28) is cou-pled to the metallic material and its output is amplified by an amplifier (30) before being input to a computer (32) which determines the damping factor. In a second method, a continuous energy input is provided to the metallic material, such as by utilizing a fre-quency generator coupled to a power ampli-fier whose output drives a transducer such as a speaker or the like for inducing a con-tinuous vibration in the metallic material. This continuous vibration is measured with a transducer, an amplifier, and a damping factor calculated with a computer as in the first method.

Title: Milling cutting insert
Inventor: HANSSON LARS-OLA
IPC: B23C5/20
Filed: 1995-10-23
Abstract: A milling cutting insert comprises an upper side (2), a bottom side (3) and flank surfaces (4) connecting these two sides. At each operative cutting corner is a projection (17), which is depressed relative to the adjacent main cutting edge (5) and corner cutting edge (6). At the front upper edge of the projection is the wiper edge (16) that generates the surface on the workpiece. By tipping the cutting insert axially positively and radially negatively, the horizontally located wiper edge may be tipped frontwards into contact with the workpiece, while the vertically located wiper edge is tipped backwardly, so that it does not reach the workpiece. In this way an improved axial clearance is made possible and an undesired groove in the workpiece is avoided, which would otherwise be caused by the vertically located wiper edge.

Title: Method, reagent and kit for evaluating susceptibility to premature atherosclerosis and treatment of same using gene therapy
Inventor: HAYDEN MICHAEL R
IPC: C12Q1/6883
Filed: 1995-10-11
Abstract: A single point mutation in the human lipoprotein lipase gene which results in an A .fwdarw. G nucleotide change at codon 291 (nucleotide 1127) of the lipoprotein lipase gene, and a substitution of serine for the normal asparagine in the lipoprotein lipase gene product is seen with increased frequency in patients with coronary artery disease, and is associated with an increased susceptibility to coronary artery disease, including in particular premature atherosclerosis. This is expressed as a diminished catalytic activity of lipoprotein lipase, lower HDL-cholesterol levels and higher triglyceride levels. Thus, susceptibility of a human individual to premature atherosclerosis can be evaluated by: (a) obtaining a sample of DNA from the individual; and (b) evaluating the sample of DNA for the presence of nucleotides encoding a serin residue as amino acid 291 of the lipoprotein lipase gene product.  Patients found to be suffering from or likely to suffer from premature atherosclerosis and other forms of coronary artery disease as a result of a lipoprotein lipase deficiency can be treated using gene therapy.
