Title: Wood type golf club head
Inventor: SOLHEIM JOHN A
IPC: A63B53/04
Filed: 1997-12-16
Abstract: A wood type golf club head includes a body having a face for impacting a golf ball, a top, a bottom, a toe end and a heel end. A sole plate made of high density material is attached to and substantially covers the bottom of the body. An insert made of low density material is disposed in an opening in a center section of the sole plate and extends into a cavity formed in the bottom of the body. By utilizing high density material for the sole plate in combination with low density material for the insert, a significant amount of weight is removed from the center of the club head which maximizes the perimeter weighting of the club head while increasing the moments of inertia of the club head. Preferably, the sole plate is made of a suitable metal such as brass, copper, bronze or nickel, and the insert is made of a suitable plastic.

Patent CA-2237961-A1 (CA)
Title: Paper machine clothings constructed of interconnected bicomponent fibers
Inventor: DAVIS ROBERT BERNARD
IPC: D03D1/00
Filed: 1997-09-12
Abstract: The present invention is directed towards paper machine clothings comprised of interconnected bicomponent fibers (1, 2). In one embodiment of the invention, the paper machine clothing is comprised entirely of bicomponent fibers in both the machine and cross machine direction. Advantage is taken of the unique bicomponent fiber structure, which permits selection of different materials for the sheath and core components. For instance, the sheath material may have a melting point lower than the melting point of the core material. Accordingly, a fused, bonded structure (5) of bicomponent fibers can be formed where the sheath component has a melting point lower than the core component. By heating a fabric constructed of bicomponent fibers to a temperature greater than the melting point of the sheath component and lower than the melting point of the core component, with subsequent cooling of the fabric to below melt temperature of the sheath component, a fused, bonded structure will result.
Patent CA-2238562-A1 (CA)
Title: Lifting apparatus
Inventor: WARD WILLIAM SIDNEY
IPC: B66F7/20
Filed: 1998-05-26
Abstract: A twin post lift has a master and slave cylinder system in which the maser and slave cylinders each drive a lifting carriage, and each of the lifting carriages is mounted within, and is restricted to longitudinal travel within, an upright member. In the event that there is a loss of pressure in the hydraulic system under load, it is important that the lift be prevented from descending unexpectedly, or uncontrolledly. The upright can be manufactured in the form of a roll formed channel section. The legs of the channel section are formed to define guides for guide followers mounted on the lifting carriage, thereby restraining the travel of the lifting carriages to travel in the vertical direction. The lifting carriage has a rack formed on its back face. The rack is nested within the upright member and is not visible in use. The back of the channel is formed with an outwardly protruding step to accommodate the rack. A safety stop, in the nature of a spring loaded safety dog, is mounted to the upright and extends through the wall of the protrusion to engage the rack.

Patent CA-2251125-A1 (CA)
Inventor: SUNLIN WILLIAM M
IPC: G01V3/12
Filed: 1997-04-15
Abstract: A ground penetrating impulse radar system provides three-dimensional images of targets. A moving array of transmitting (52a, 52b) and receiving (56a, 56b) antennas provides narrow beamwidths and high gain by real and synthetic aperture beam processing. Narrow pulsewidth impulse signals (72a, 72b) are utilized to obtain high resolution. Round trip time is calculated for each three-dimensional pixel in a search volume (24), and is used to process three-dimensional imagery (96). Analog to digital conversion (82a, 82b) can be utilized, so all signal processing is accomplished digitally. The radar system is applicable to detecting small objects (30) near the surface by using very narrow pulses, and also can be applied to detect large, deep objects by wider pulses.
