Patent CA-2123531-A1 (CA)
Inventor: EGGIMAN MICHAEL D
IPC: A63B59/06
Filed: 1994-05-13
Abstract: A tubular aluminum bat frame is provided with a large-diameter impact portion, an intermediate tapering portion, and a small-diameter handle portion. A tubular insert is suspended within the impact portion by interference fits at each insert end. A first interference tit is achieved by forcing the first end of the insert into the tapering portion of the bat frame. The second interference-fit is then formed by curling the end of the impact portion over upon the second end of the insert. A gap exists along the length of the suspended insert separating the insert from the interior of the impact portion. The gap is filled with grease to facilitate relative movement between the insert and the tubular frame when a ball is batted.

Patent CA-2126412-A1 (CA)
Title: Bag folding and stacking apparatus
Inventor: WOGELIUS DONALD E
IPC: B65H45/16
Filed: 1994-06-21
Abstract: BAG FOLDING AND STACKING APPARATUS                 ABSTRACT OF THE DISCLOSURE      The present invention features a high-speed folding and stacking system for the manufacture of plastic bags.  The system is made up of a series of rotating, interdigitating drums.  The drums mechanically pick-off and fold twice the plastic bags prior to stacking.  The series of drums consists of a first "tucking" drum; a second "tucking and gripping" drum; and a third, "gripping" drum having specialty grippers.  The first drum of the folding apparatus obtains from a feed drum plastic bags that have already been sized.  Transfer from the feed drum is via the vacuum and air pressure feed mechanisms commonly employed in these arts.  As one bag comes upon the tucking drum, another bag leaves the drum.  The first drum tucks the exiting bag into a mechanical gripper located on the second drum ("the tucking and gripping drum"), as it synchronously rotates into position to meet the first drum.  The second drum puts a first fold into the plastic bags carried on its periphery.  As one bag enters the second drum, it is gripped about its center and rotatively swept over the periphery of the drum, which causes it to be folded once.  The gripper of the third gripping drum puts a second quarter-fold into the "singly folded" bag leaving the second drum.  The gripper of the third drum is especially designed to pivot as it releases the doubly folded bag, thus preventing formation of a kink that results from the gripping of the bag and the subsequent releasing of the gripped bag to the first feed belt of a stacking apparatus.

Title: Method of Forming Tapered Orifice Arrays in Fully Assembled Ink Jet Printheads
Inventor: HAYES DONALD J
IPC: B23K26/38
Filed: 1992-12-18
Abstract: A method of forming an outwardly tapered orifice for a fully assembled ink jet printhead. A main body portion and a cover plate for an ink jet printhead are mounted together such that the cover plate covers an ink-carrying channel which axially extends through the main body portion. First and second light beams capable of ablating the material used to form the cover plate are generated and an ink-carrying channel communicating orifice extending through the cover plate and tapering outwardly from a front side of the cover plate to a back side of the cover plate is formed by directing the first and second light beams at the front side of the cover plate at first and second angles, respectively, whereby the first and second light beams form the outwardly tapered orifice.

Title: Fast packet switch
Inventor: DUXBURY TOM
IPC: H04L12/433
Filed: 1994-07-28
Abstract: The invention provides a very fast distributed frame relay switch. Each switching element is tied to each other switching element using LAN like FDDI technology. Frame relay packets arrive into the switch via lower speed TDM based trunks and can either be switched locally within the same switching element or can be switched to a remote switching element via the FDDI bus. The switching elements themselves reside in a TDM based multiplexer, thus can utilize existing TDM interfaces.

Title: Method and apparatus for constructing a frame buffer with a fast copy means
Inventor: FORREST CRAIG S
IPC: G06T1/60
Filed: 1994-08-12
Abstract: A method and apparatus for quickly copying a first frame region into a second frame region. A video memory array comprising a plurality of video random access memory devices is divided into at least two frame regions. A background image is rendered by a central processing unit into a background frame region within the video memory array. The central processing unit then requests the background image in the background frame region to be copied into a new frame region in the video memory array. A dedicated circuit copies the entire background image in the background frame region into the new frame region. The dedicated circuit operates by using a serial data register within each video random access memory device during the vertical retrace period of a video timing signal. The dedicated circuit performs the background frame copy without requiring any processing resources from the central processing unit,

Title: Method for recovering carboxylic acids from aqueous solutions
Inventor: GENTRY JOSEPH C
IPC: C07C53/00
Filed: 1995-03-16
Abstract: Disclosed is a method for recovering carboxylic acids having from one to ten carbon atoms, and particularly formic acid, acetic acid and mixtures of formic and acetic acids, from aqueous solutions, in which the aqueous solution is contacted with solvent consisting essentially of mixed trialkylphosphine oxides in counter-current liquid-liquid extraction flow in a contacting step to thereby transfer the acids from the aqueous solution to the solvent, thus producing a raffinate relatively low in acid content and a rich solvent. The rich solvent is preferably dehydrated to separate water therefrom and yield a dehydrated rich solvent.  The dehydrated rich solvent then has the acids stripped from it and the resulting lean solvent is then returned to the liquid-liquid extraction step, while the separated acids are split into their constituent components in a distillation operation.

Title: Extended range regenerative pump
Inventor: MOSS NORMAN
IPC: F04D23/00
Filed: 1995-05-10
Abstract: A regenerative or toric pump adds energy to a fluid using an impeller having an axis of rotation and axially spaced, radially extending first and second surfaces.  A casinq encloses the impeller and has a fluid inlet and a fluid outlet separated by a stripper.  The casing has axially spaced, radially extending first and second sidewalls facing the first and second surfaces of the impeller respectively.  Axially and radially extending blades or vanes are formed on an outer radial periphery of the impeller for driving fluid from the inlet toward the outlet as the impeller rotates about the axis of rotation.  A fixed surface is formed in at least one sidewall of the casing for directing fluid back toward the impeller.  Improved operating characteristics and extended range are accomplished through modification to the vane configuration of the impeller and/or by modification of the side channel configuration of the pump chamber in an asymmetrical fashion.
