Title: Secondary gas/liquid mechanical seal assembly
Inventor: SALANT RICHARD F
IPC: F16J15/34
Filed: 1992-11-10
Abstract: A secondary mechanical seal assembly is used on a shaft (12) that is rotatable within a housing (14) to seal both gaseous and liquid medium (20). The assembly (18) includes a stationary seal face element (26) that is fixed relative to the housing and a rotating seal face element (24) that is fixed relative to the shaft (12). One of the seal face element (24-26) back surfaces (34) includes at least one slot (40) configured to produce a wave on the front surface (32) of the seal face element (24-26) when the shaft (12) is rotated. The wave creates an opening force that is sufficient to control wear and prolong seal life when the secondary seal assembly (18) is exposed to a gaseous medium. When exposed to a pressurized liquid medium, the hydrodynamic loading from the liquid medium alters the seal face element (24-26) waviness, and increases the closing force due to the action of the pressurized liquid on the back surface of the seal face elements, such that excessive leakage is prevented.

Patent CA-2128938-A1 (CA)
Inventor: CHANG SHIAO H
IPC: B29C43/00
Filed: 1994-07-27
Abstract: The polymethyl methacrylate (PMMA) or copolymer thereof used to produce one-piece intraocuiar lenses is modified by a compression molding process to produce a much tougher material with improved mechanical properties. The process takes material in rod form and compresses into lens blanks. The molded lens blanks receive little or no compression strain in the center 4 man optic zone. The compression is limited to the periphery region outside the center 4 mm zone. The intraocular lens fabricated from the molded lens blank exhibits greatly increased haptic mechanical properties and resistance to breakage.

Abstract: A  self-positioning  light  fixture  with a stabilizing base  comprises  a  self-righting  member  in the shape of a spherical segment and a separate lamp supporting member with connecting  means  to  join the two together and to separate each from the other. When separated, a filling neck or spout on  the  top  wall  of  the  self-righting member is exposed through  which  fluid  ballast  material such as sand may be poured  into  the  cavity  of  the self-righting member. The filling  neck  has  external  threads to engage the internal threads  of  a recess opening to the bottom wall of the lamp supporting  member  when  received therein to thereby couple the  two  members  together. Additional fastening screws are provided  to  more securely connect the self-righting member to  the  lamp supporting member.

Title: A cdma communications method and system
Inventor: ADACHI FUMIYUKI
IPC: H04W76/02
Filed: 1994-11-02
Abstract: A CDMA communications method capable of multiplex transmission of data over a wide range from a low rate to high rate such as image data without a considerable increase in a circuit scale. A fundamental transmission rate is determined, for example, at 32 kbps, a rate higher than 8 kbps conventionally used. The data whose transmission rate is equal to the fundamental transmission rate is transmitted in frames including no vacant portion. Data whose transmission rate is lower than the fundamental transmission rate (16 kbps, for example) are transmitted in frames including vacant portions. The vacant portions are not transmitted. This makes it possible to receive data through other channels during a time period associated with the vacant portions. Data of a higher transmission rate, 128 kbps, for example, can be multiplexed and transmitted through four channels using different spreading codes.

Title: Vacuum web coating
Inventor: BAXTER IAIN K
IPC: C23C14/56
Filed: 1994-11-09
Abstract: ABSTRACT          VACUUM WEB COATING    In an apparatus for vacuum web coating, an evaporation means has a plurality of separately spaced outlet nozzles through which vapour is conveyed to a deposition zone at the surface of a chilled rotatable drum in a vacuum chamber over which drum the substrate web is advanced by a web transport system.      The outlet nozzle arrangement advantageously comprises a plurality of linear slots disposed transversely to the web substrate path to deliver vapour at positions disposed sequentially in the direction of the web substrate advance, the nozzle outlets being disposed on an arcuate surface around,  but  spaced  from,  the  curved  surface  of  the rotatable drum.      By varying the nozzle profile, for example the width and/or spacing of the nozzle outlets the application of the coating  may  be  tightly  controlled  to  obtain  improved uniformity of the coating, material collection efficiency and control of the substrate heat loading.  The apparatus is particularly suitable for applying  thick coatings of material such as metal on paper or plastic films.

Title: Method of generating a random element as well as a method for traffic mixing, random element generator and system component therewith
Inventor: WAHL STEFAN
IPC: H04L12/54
Filed: 1995-11-23
Abstract: For traffic mixing, random generators with feedback shift registers are usually used.  A simpler, lower cost implementation involves generating a random element in a device that detects nondeterministic events already occurring in operation of the device and mapping them to the random element by means of an assignment rule.  The traffic mixing in an ATM switching element (SE) is achieved cyclically writing data packets into a buffer (MEM) and cyclically reading data packets out of a buffer (MEM).  The write cycle in this case is clocked by the arrival of a data packet, that is, by a nondeterministic event.  The read cycle is clocked by a stable clock signal.

Title: Baton de golf universel a trois tetes et tige telescopique ajustable
Inventor: ALVAREZ JOSE MANUEL
IPC: A63B53/06
Filed: 1996-03-26
Abstract: Dans une partie de golf, le joueur utilise quatorze (14) bâtons: des bois, des fers et un fer droit putter. Ces bâtons ont des angles de frappe différents qui permettent au joueur de frapper la balle plus ou moins loin, selon la distance àparcourir, et un fer droit pour jouer sur le vert, et mettre la balle dans le trou. Il existe aussi des bâtons de golf à tête et à tige ajustables avec des angles de frappe différents; généralement ces types de bâton manquent de stabilité à l'impact et ne peuvent représenter les parties convexes des bois. La PRESENTE INVENTION est un bâton de golf unique à trois surfaces de frappe ajustables (13 positions), qui permet de choisir la surface de frappe et l'angle désiré correspondant à tous les bois et les fers d'un jeu conventionnel. La surface de frappe plate reproduit les fers. Les deux autres surfaces de frappe équivalant aux bois ont des rayons de courbure convexes dans les deux axes qui permettent la correction de l'impact. Le fer droit Putter est reproduit par la face du bois un avec un angle de 4.degree.. Les bases des trois surfaces en contact avec le sol et l'angle d'attaque par rapport à la balle sont assurés par les rayons de courbures convexes dans les deux axes. Le verrouillage de l'angle choisi est fait par l'insertion de l'une des deux goupilles de blocage se trouvant dans l'adapteur à tige. On règle la longueur de la tige télescopique avec une vis de blocage. La torsion est empêchée par un système de blocage sécuritaire comportant un coulisseau carré sur lequel est insérée la poignée ronde. Le poids du bâton est allégé par l'évidement de la tête ajustable.
