Patent CA-2243908-A1 (CA)
Title: Noise reducing diffuser
Inventor: AWAD ELIAS A
IPC: F16L55/02
Filed: 1998-07-24
Abstract: A noise reducing diffuser which reduces the sound energy created by a pressurized gas while it is being expelled through a nozzle. The diffuser consists of an elongated enclosure with openings at each end that is attached to the output of the gas nozzle. The dimensions of the enclosure, particularly its distance from the sound source, effective diameter and length, are chosen to specifically eliminate audible noise created by the escaping gas by conversion of a portion of the longitudinal component of the sound energy to an increased radial component that can then be dissipated by repeated contact with the wall of the elongated enclosure.

Title: Metering particulate material
Inventor: SLABIK JEFFREY MARK
IPC: A01C15/00
Filed: 1998-08-05
Abstract: A supply tank for the individual openers of an air seeder includes two separate tank elements each formed from two separate tanks. Each opener has two supply ducts, one from each tank element. Each tank has a dispensing roller across its bottom metering material into the separate supply ducts. The two tanks of each element feed into a common tube within a closed enclosure dispensing into a feed end of a respective pipe for a respective one of the openers. The pipes within the enclosure are monitored by a camera system so that the operator can see the dispensing of the material on a monitor screen. The tanks are covered by a sealed lid which pivots about a vertical post at one edge. An air supply pressurizes the tanks and a heater selectively heats the air to one of the tanks selected for supplying fertilizer.
Patent CA-2246713-A1 (CA)
Title: A method and apparatus for performing minimally invasive cardiac procedures
Inventor: UECKER DARRIN R
IPC: A61B19/00
Filed: 1997-02-19
Abstract: This invention is a system (10) for performing minimally invasive cardiac procedures. The system includes a pair of surgical instruments that are coupled to a pair of robot arms (16, 18). The instruments (22, 24) have end effectors that can be manipulated to hold and suture tissue. The robotistic arms are coupled to a pair of master handles (50, 52) by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position.

Patent CA-2249759-A1 (CA)
Inventor: KITAIN EDUARD
IPC: G06F17/30
Filed: 1998-10-07
Abstract: The electronic distribution of research documents over the world wide web or other network to investors. A repository server receives research documents from contributors. A restriction subsystem server is selectively coupled to the contributor workstation. The restriction subsystem server which includes manages and stores "restriction" and "review" information of companies, relative to contributors. A contributor identifies (via electronic communication or otherwise) to the restriction subsystem server a "restriction" and/or "review" status of a company relative to the contributor. A particular company may be identified as "RESTRICTED" if the contributor has a current banking or financial interest in the company. Additionally, a company may be identified as "UNDER REVIEW" if the contributor believes its opinion about the company may change based on a news event. Moreover, a company may be identified as "UNDER EXTENDED REVIEW," if, for example, the contributor is not presently "covering" that company. Each time the repository server is queried for a list of reports or documents (i.e., document titles or headlines), the repository server determines whether to provide a particular title to the viewer workstation (via a viewer server or web server) to the user based on the restriction status of the contributor of the document relative to the restriction status of the company or companies associated with the document.

Title: Artificial joint, in particular an artificial hip joint
Inventor: SEMLITSCH MANFRED
IPC: A61F2/00
Filed: 1997-03-06
Abstract: With the invention, a geometry is described which makes it possible to use similar, wear-resistant, metallic materials such as PROTASUL 21 WF for a bearing shell (1) and a joint ball (2) in a spherical bearing without micro-weldings and without excessive wear arising, while other properties such as toughness, stability of shape and elasticity can be exploited for the function. Micro-weldings of the similar metallic materials are largely prevented by a suitable relationship between the average radii R m, r m of the bearing surfaces A and B as well as of the permissible deviations (12, 13) in shape and of the permissible roughness of the bearing surfaces.

Abstract: A shell for sports shoes, particularly for Telemark skiing, which comprises a sole and a lateral surface which surrounds the foot of the user. A frame is rigidly coupled internally to the shell and has a foot resting surface and a toe cup which partially extends over the upper metatarsal region. On the resting surface and on the toe cup there are, respectively, at least one first transverse opening, arranged below the metatarsal region, and at least one second transverse opening, which lies above the metatarsal region. A transverse bridge, arranged in the region that lies to the rear of the metatarsus, is thus formed at the toe cup. The resulting shell is therefore highly flexible but torsionally rigid, making it easier for the user to ski.

Title: Refrigerated fuel for engines
Inventor: KOETHE TERENCE LEE
IPC: F02M31/20
Filed: 1997-03-17
Abstract: A method of fueling an engine (92) of a vehicle having a fuel storage tank (70) is accomplished by providing a liquid fuel for fueling the engine (92). The fuel is cooled to reduced temperatures substantially less than ambient temperature so that the volume of the fuel is reduced. The fuel is stored in the storage tank (70) while the fuel is at the reduced temperatures, with the reduced volume of the fuel thereby allowing more fuel to be held in the storage tank (70) and/or increasing the energy value of the fuel per unit volume. The fuel may be transferred from the storage tank (70) to the engine (92) while the fuel is at the reduced temperatures. The fuel may be cooled using either liquid nitrogen (76), or conventional mechanical refrigeration equipment (150).
