Abstract: A tool bit for use in at least one of a drilling and cutting operations is formed of an axially extending carrier member and a cutting member.  The cutting member has an expansion joint extending parallel to the axis of the carrier member.  The expansion joint is formed by reducing the thickness of the cutting member so that material webs remain.  In the fabrication and formation of the tool bit, the cutting member is a single unit.  In the use of the tool bit, due to the expansion joint the cutting member forms individual operating units affording reduced material expense of the cutting member, because of reduced stresses.

Granted: 2007-03-06
Abstract: A thermoplastic resin such as a styrene/maleic anhydride copolymer is treated to remove volatile impurities such as unreacted styrene by admixing with a chemical blowing agent and extruding under a vacuum. The chemical blowing agent is converted into an inert gas such as carbon dioxide during extrusion; the gas evolved is removed, together with the volatile impurities, through one or more vents in the extruder. The use of a chemical blowing agent, rather than the inert gas itself, permits the facile distribution of the CO2 stripping agent throughout the molten thermoplastic resin using commonly available extruders without the need for elaborate gas injection means.

Patent CA-2170336-C (CA)
Inventor: CESHKOVSKY LUDWIG
IPC: G11B21/08
Filed: 1996-02-26
Granted: 2002-12-10
Abstract: The present invention allows the light beam of an optical disc storage device to radially move between different information tracks of an optical disc while the storage device tracking servo loop remains in a continuous closed loop mode of operation. The invention operates to radially move a light beam from one information track to another during a closed loop mode of operation by activating two control signals introduced into the closed tracking servo loop to create a phantom track center that radially moves across the optical disc. Because the tracking servo loop is in a closed loop mode of operation, the tracking servo operates to keep the light beam centered on the point that the tracking servo considers to be the center of an information track; in this case the phantom track center. Therefore, the tracking servo causes the light beam to radially move across the disc in a closed loop mode of operation by keeping the light beam centered on the moving phantom track center.

Abstract: An improved arc-resistant switchgear enclosure is disclosed.  In preferred embodiments, an internal arc chamber is formed by assembling modules and creating a void within the center of the switchgear enclosure. As multiple compartments or modules for a switchgear enclosure are connected, an arc chamber is created within the enclosure. Upon initiation of an arc fault within a particular compartment, a relief flap or cover for that particular compartment opens to channel the pressure and the gases into the internal arc chamber or directly through the top of the enclosure. Pressure and gases vented into the internal are chamber flow horizontally through the arc chamber until a path to the top of the switchgear enclosure is reached. These, pressures and hot gases are then channeled upward and safely out of the switchgear enclosure.

Title: Double-disc refiner
Inventor: AIKAWA YOSHIHIKO
IPC: D21D1/30
Filed: 1996-12-30
Granted: 1999-08-03
Abstract: A double-disc refiner of the invention is formed of a driving shaft having one free end, a rotating disc fixed on the driving shaft and having a first rotating blade provided on one surface and a second rotating blade provided on the other surface thereof, and a crushing chamber surrounding the rotating disc, and first and second a material supply passages.  On an inner wall of the crushing chamber, a first stationary blade is disposed to face the first rotating blade, and a second stationary blade is disposed to face the second rotating blade.  An end surface of the one free end of the driving shaft is located in the first paper material supply passage, and includes projections to closely face a portion of the first paper material passage to prevent the material flowing through the first material supply passage from entering between the portion and the projections.  Therefore, on the end surface of the driving shaft, pressure caused by the material is reduced to equalize spaces between the respective rotating and stationary blades.

Abstract: In the production of mailer type business forms, particularly from a web in a roll configuration having a plurality of business form intermediates, with pressure sensitive cohesive, the problem of cohesive blocking (sticking together) at inopportune times is avoided by spacing substantially linear patterns of the cohesive disposed in the detachable side edges of the intermediates so that when the intermediates are in the roll configuration the cohesive from one intermediate does not engage the cohesive from another. Preferably the cohesive patterns on one face of the intermediate are spaced from the parallel cohesive patterns on the second face of the intermediate by about 1-15 mm, preferably about one centimeter. Transversely extending patterns of cohesive also may be positioned so that they too do not engage in the roll configuration, even though engagement of the transverse patterns is much less of a problem because the potential areas for engagement are few when the intermediates are in the roll configuration.

Abstract: Dans un système dans lequel des informations codées peuvent être protégées et mises à jour par de multiples utilisateurs utilisant des mots de passe de concert, un fichier avec des données protégées contient à la fois un en-tête non codé et une partie données codées. Cette partie données contient à la fois les données protégées et une liste de mots de passe hachés et est codée avec un seul code de fichier. L'en-tête de fichier non codé contient deux tables. La première est une liste de mots de passe, dans laquelle chaque mot de passe subit un hachage cryptographique à l'aide d'une deuxième technique de hachage différente de celle des mots de passe hachés dans la partie données du fichier. La deuxième table est une liste de combinaisons, ayant subi un hachage cryptographique, de mots de passe ayant eux aussi subi un hachage cryptographique, liste dans laquelle ces combinaisons correspondent à des quorums d'utilisateurs agréés et les mots de passe sont hachés à l'aide de la même technique que celle relative aux mots de passe mémorisés dans la partie données du fichier. Chaque combinaison hachée sur la liste sert également de code de mot de passe pour chiffrer le code fichier. Lors de l'utilisation du système, un utilisateur agréé doit introduire un mot de passe qui, lors du hachage, peut être localisé dans la première table. Si le mot de passe introduit est localisé dans la première table, un contrôle est effectué pour déterminer si une quantité suffisante d'utilisateurs agréés ont introduit des mots de passe pour former un quorum. S'il existe un quorum, les mots de passe des utilisateurs le constituant sont hachés à l'aide de la première technique de hachage, combinés et hachés de nouveau pour former un code de mot de passe. Le code de fichier peut être décrypté à l'aide du code de mot de passe et utilisé pour décrypter le fichier. Les mots de passe hachés dans la partie protégée du fichier peuvent ensuite être utilisés pour mettre à jour les listes de mots de passe.

Title: Heat exchanger efficiency control by differential temperature
Inventor: THOMPSON WILLIAM L
IPC: B01D53/74
Filed: 1997-05-08
Granted: 2005-05-03
Abstract: A regenerative thermal oxidizer (H-101) includes a number of heat exchange columns (A, B) topped by a combustion chamber (C-101). Contaminated air is directed into one of the columns and oxidation is completed as the flow passes through the combustion chamber (C-101). From the combustion chamber (C-101), the now clean air flows vertically downward through another column and then is directed via an outlet valve through an outlet manifold and released to atmosphere or recirculated back to the oxidizer (H-101). A combustible fuel is added to the contaminated air prior to its entry into one of the columns. The addition of the combustible fuel is regulated by continuously monitoring the inlet and outlet temperatures (TE-101A, TE-108A), and comparing a difference between these temperatures to a predetermined value. Further control can be achieved by measuring the flow of contaminated air to the oxidizer (H-101) via pressure differential and coordinating that measurement with the temperature differential measurement.
