Title: Moving and mixing of microdroplets through microchannels
Inventor: BURNS MARK A
IPC: B01L3/00
Filed: 1998-09-25
Abstract: The movement and mixing of microdroplets through microchannels is described employing microscale device. Sample and reagent are injected into the device through entry ports (A) and they are transported as discrete droplets through channels (B) to a reaction chamber, such as a thermally controlled reactor where mixing and reactions (e.g., restriction enzyme digestion or nucleic acid amplification) occur (C). The biochemical products are then moved by the same method to an electrophoresis module (D) where migration data is collected by a detector (E) and transmitted to a recording instrument. Importantly, the fluidic and electronic components are designed to be fully compatible in function and construction with the biological reactions and reagents.

Title: Nondestructive testing of dielectric materials
Inventor: LITTLE JACK R JR
IPC: G01N22/00
Filed: 1998-09-22
Abstract: An apparatus and method for the nondestructive inspection of dielectric matierals are disclosed. Monochromatic, phase coherent electromagnetic radiation (6), preferably in the 5-50 gigahertz frequency range (i.e. microwaves) impinges on the sample. In accordance with Snell's law, the microwaves are partly transmitted and partly reflected at each interface where the dielectric constant changes due to irregularities. A portion of the reflected beam is combined with the signal reflected by the specimen being inspected. These two signals have the same frequency, but may differ in amplitude and phase. The signals combine to produce an interference pattern, a pattern that changes as the specimen changes, or as the position of the specimen changes relative to a detector (2, 4). A computer (10) is programmed to distinguish features in the interference pattern attributable to irregularities in the material from features in the interference pattern attributable to sources of noise.

Abstract: The present invention relates to a veneer cutting machine used for cutting wood veneer coming from a veneer lathe in a direction transverse to the veneer travel. The cutting machine comprises a blade-supporting beam (1) extending transversely across the veneer to be cut and having a blade (2) mounted thereon, the blade-supporting beam performing in a controlled manner a reciprocatory stroke in a direction substantially perpendicular to the plane of the veneer, and a movable anvil (4) aligned to coincide with the beam with the blade mounted thereon, whereby the veneer (5) to be cut is passed via the gap remaining between said coinciding members. According to the invention, the blade (2) is mounted on the blade-supporting beam in a manner allowing the blade to tilt in the downstream travel direction of the veneer and the anvil (4) is arranged to move at the cutting point in the same direction and at the same speed with the veneer (5) being cut. The arrangement is capable of preventing all factors that could impede the travel of the veneer being cut.

Patent CA-2314296-A1 (CA)
Title: Disposable absorbent shoe insert
Inventor: JANZEN KATHERINE E
IPC: A43B17/10
Filed: 2000-07-19
Abstract: A pair of disposable absorbent shoe inserts includes first and second inserts, each including a porous upper layer which allows moisture to pass from the user's foot into an absorbent middle layer. A lower surface of the absorbent middle layer is attached to an impervious lower layer 40 which prevents moisture contact with the insole of the shoe. A lower surface of the impervious lower layer is attached to a release material layer 50 having a first pattern. A second shoe insert is similarly constructed, but provides a release material layer having a second pattern which is approximately a mirror image of the first pattern, and is non-overlaying to the first pattern. As a result, each insert acts as a release layer for the other insert. The layers of each insert are ultra thin and are bonded together to form a tapered edge around the circumference of the insert. An adhesive layer 60 is carried between the release layers of the first and second shoe inserts, thereby forming the pair of disposable absorbent shoe inserts. In use, due to the mirror image nature of the release material layers 50, approximately half of the adhesive layer is deposited on the lower surface of each impervious lower layer.

Title: A ventilator apparatus
Inventor: YOUNG DAVID
IPC: D21F5/04
Filed: 1998-09-10
Abstract: A ventilator apparatus (10) is disclosed for supplying air from a source of pressurized air (12) between a dryer (14) and a web (W) supported by a felt (F) extending around a roll (16) of a single tier drying section (18). The apparatus includes a housing (20) which is connected to the source of pressurized air. The housing defines a nozzle (22) for directing a flow therethrough of a current of air (24).    The flow is directed from the nozzle towards a diverging nip (DN) defined between the dryer and the web supported by the felt when the felt diverges away from the dryer prior to the felt extending around the roll. The arrangement is such that the flow of air compensates for an underpressure generated by the felt when diverging away from the dryer so that fluttering of the web is inhibited.

Title: File system locking
Inventor: HUTCHISON ROBERT BRIAN
IPC: G06F9/46
Filed: 2001-02-09
Abstract: A method and system for managing process requests between and application program and an operating systems managing processes. Process requests and, in particular, file locking or unlocking requests from an application program written on one operating systems may causes files to be corrupted if the application program is ported to a new operating system without rewriting portions of the program code. A file locking emulator is used between an application program and an operating system. The file locking emulator comprises an application program interface and a file lock supervisor. The file locking emulator receives the file locking requests from the application program and generates file requests and file lock query commands. When the application program interface receives a file request it first checks the files lock status and then either returns an error for incompatible file requests or executes the compatible lock request along with any other compatible operation request such as a read, write or truncate file operation. Incompatible file locking requests return an error statement which may include error recovery options available to a user of the application program. The status of files accessed by the application program are stored in file lock managers. Only code in the file request emulator needs to be rewritten when an application program is ported to different operating systems sharing incompatible but executable processes. In this manner tested code of the application program does not have to be rewritten.
