Title: Speed-increased small boat
Inventor: OSAWA MASAKAZU
IPC: B63B1/40
Filed: 1993-11-24
Granted: 2002-02-26
Abstract: The speed of a high-speed powered boat such as high-speed fisherboats can be increased even at the same power output of the engine irrespective of the speed by providing on each side symmetrically with a plural number of fins each opening outwardly toward the rear end making an angle with the boat hull in at least two high and low rows along the waterline which varies depending on the speed of the boat, whereby the wave-making resistance against the boat is greatly reduced at varied speed of the boat along with a stabilizing effect to decrease rolling. The effect of wave-making resistance suppression can be further enhanced by providing the bow of the boat with a stem-edge guard with right and left wings opening outwardly toward the side lines.

Title: Bandgap tuning of semiconductor quantum well structures
Inventor: CHARBONNEAU SYLVAIN
IPC: H01L21/18
Filed: 1994-12-12
Granted: 2004-05-04
Abstract: A method of selectively tuning the bandedge of a semiconductor heterostructure includes repeatedly forming a disordered region that is spatially separated from a quantum well active region and subsequently annealing the heterostructure each time after the disordered region is formed, so that vacancies/defects in the disordered region diffuse into the quantum well region and enhance interdiffusion at the well-barrier heterojunctions. Repeating, the disordering followed by annealing allows for a greater range in bandgap tuning. The heterostructures of interest are III-V material systems, such as AlGaAs/GaAs, where the active region includes structures such as a single quantum well, a multiple quantum well, or a superlattice.
Patent CA-2145943-C (CA)
Inventor: OBOSU CHARLES B
IPC: F28F1/32
Filed: 1995-03-30
Granted: 1999-04-13
Abstract: The present invention involves a flat fin heat exchanger configuration with a plurality of louvers and a rib raised above the plane of the fin connecting adjacent tube collars.  The raised rib configuration enhances the heat transfer characteristics of the fin, and allows for the use of thinner materials to lower cost without diminishing performance.  The exterior fin surface "scoops" and redirects air flow from the leading edge to the trailing edge of the fin.  This "scooping" effect directs the air flow over and in between the interrupted surfaces, thus breaking up air boundary layer around the fin.  The louvers of the fin are oriented relative to the air flow in such a manner that each louver in effect creates another leading edge contributing to a higher heat transfer coefficient.  Also, the location of the raised rib also enhances the heat transfer between the fin and the circulated air.  The fin collars are also surrounded by a raised portion so that one raised rib and its two adjacent raised portions bordering the collar form a "dog bone" type shape.  The leading and trailing edges are serrated to improve the structural rigidity and create turbulence in the air flow.  Also, the leading and trailing edges are oriented at a slight angle, e.g., 12°, relative to the plane of the fin.  The louvers are oriented at a slightly greater angle than the leading and trailing edges, e.g., 20°-35°.

Abstract: An apparatus and a method for attaching articles (11) to a plastic bag wall (10') and particularly for attaching flat articles (11), such as coupons, cards, packets, samples, etc, to an inside wall of a panel of the bag and at different locations thereon. The articles (11) are attached by feeding a bag-forming film sheet (22) of plastic material to an article insertion station (24) where the plastic sheer (22) passes about a nip roll (26). An article transfer mechanism (30) transfers articles (11) from a discharge end of one or more supply magazines (29) to two or more support surfaces (42) at an article insertion station (40). These support surfaces (42) are aligned with distinct sections of the bag-forming film sheet (22). An attaching film sheet (28) is fed over a support roll (27) which is in frictional rotational contact with the nip roll (26) with the attaching film sheet (28) aligned over the distinct sections of the bag-forming film sheet. The nip roll (26) is moved in the direction towards the support surface (42) to grasp a leading edge (11') of an article (11) positioned on the support surface (42) to position same between the bag-forming film sheet (22) and the attaching film sheet (28) along the distinct sections. The two sheets are then sealed together with the article captive therebetween. The composite film can then be fed to a bag-forming station.

Patent CA-2164586-C (CA)
Title: Slitted absorbent members for aqueous body fluids formed of expandable absorbent materials
Inventor: LAVON GARY DEAN
IPC: A61F13/53
Filed: 1994-05-26
Granted: 2000-01-25
Abstract: This application relates to the use of slitted regions in absorbent members formed of absorbent materials that remain relatively thin until wetted with such fluids. Suitable materials include presently preferred varieties of polymeric foam materials. Single and multi-layered absorbent members incorporating slitted regions are disclosed, as well as the use of pre-formed cup-shaped slits for enhanced initial fluid acquisition. Such slitted regions in combination with planar expansion properties enable the absorbent members to respond dynamically to various fluid loading conditions to create useful structural features. The slitted regions, in combination with absorbent materials having expansion potential in at least one direction within the plane of the absorbent member, cause the slitted regions to buckle and/or deform out of the plane of the absorbent member, thereby causing the slit surfaces to displace angularly and/or translationally with respect to one another. This more fully exposes the slit surfaces to the incoming fluid for improved acquisition capabilities. The use of pre-formed cup-shaped slits enables the absorbent member to more quickly capture and absorb aqueous body fluids, and is particularly useful for containment and dewatering of moist or runny fecal material and higher viscosity fluids and/or those having a higher concentration of particulate material therein such as blood, menses, or wound fluids.

Title: Manufacture of paper
Inventor: CUTTS PAUL KENNETH
IPC: D21H21/10
Filed: 1995-06-01
Granted: 2007-10-02
Abstract: Paper is made by forming a thick stock cellulosic suspension, flocvulating the thick stock by adding a relatively high molecular weight and relatively low cationic charge density polymer, diluting the flocculated thick stock to form a thin stock and then draining the thin stock to form a sheet. Usually coagulant is added to the thin stock before drainage and best results are achieved by adding coagulant followed by anionic colloidal material such as bentonite. The process can be operated to give good retention and good formation and, if the thick stock is dirty, to minimise pitch problems.
