Patent CA-2152623-A1 (CA)
Title: A process for forming a carrier material
Inventor: LO FREDERICK YIP-KWAI
IPC: C08F210/14
Filed: 1993-12-13
Abstract: A support containing methylaluminoxane and derivatives thereof is formed by an incipient impregnation of a silica support so that the solution of the aluminoxane fills the pores in the support with no solution left out. The supported aluminoxane eliminates the problem of fluid bed reactor fouling during gas phase polymerization of olefins in the presence of added metallocenes. The fluid bed reactor (10) is a vertical enclosure with a reaction zone (12), comprising a bed of growing polymer particles and a minor amount of catalyst particles fluidized by the continuous flow of polymerizable and modifying gaseous components, a velocity reduction zone (14), where entrained particles are given opportunity to drop back into the fluidized bed, and a distributor plate (20). The unreacted gas passes through a cyclone separator (22), a filter (24), a compressor (25) and a heat exchanger (26). The distribution plate (20) serves the purpose of diffusing recycle gas through the bed at a rate sufficient to maintain fluidization.

Abstract: A hermaphroditic ball and socket joint permits a ball to rotate freely within a socket within constrained bounds. The socket resides within a housing that has an exterior surface having a rotational axis of symmetry passing through the center of the socket. A channel connects the socket to the exterior surface. The ball extends from a member having a collar which partially enshrouds the ball and which has an inside surface that is substantially identical to the exterior surface of the socket housing and which has an axis of rotational symmetry passing through the centre of the ball. The free rotation of the ball in the socket is constrained by the restricted movement of the member through the channel and the restricted rotation of the collar around the exterior surface of the housing.

Patent CA-2163221-A1 (CA)
Inventor: LALANCETTE JEAN-MARC
IPC: C01B32/20
Filed: 1993-05-21
Abstract: A process for the use of elemental chlorine, as a gas, in high temperature processes consists in circulating chlorine in a graphite reactor which has a double wall chamber. In the space defined by the double wall, a pressure of either nitrogen, argon or helium is maintained at a value higher than the pressure inside the reactor. In so doing, a radial diffusion of the gas within the wall towards the lower pressure zone inside the reactor is maintained through the graphite wall, thus sweeping to the inside of the reactor any chlorine that would otherwise diffuse radially outward and corrode rapidly the outer metallic shell of the reactor.

Inventor: CHAN JOSEPH
IPC: G10L25/93
Filed: 1996-02-13
Abstract: A method and an apparatus for reducing the noise in a speech signal capable of suppressing the noise in the input signal and simplifying the processing. The apparatus includes a fast Fourier transform unit 3 for transforming the input speech signal into a frequency-domain signal, and an Hn value calculation unit 7 for controlling filter characteristics for filtering employed for removing the noise from the input speech signal.

Title: Compositions and methods for the administration of .delta.-aminolevulinic acid and pharmaceutical equivalents thereof
Inventor: MANTELLE JUAN A
IPC: A61K47/26
Filed: 1995-08-28
Abstract: A pharmaceutical composition of increased stability, which comprises ALA or pharmaceutical equivalents thereof and a pharmaceutically acceptable, flexible, finite carrier suitable for administration to the skin or other dermal membrane of a mammal, optionally containing a stabilizing amount of an organic weak proton donor or saccharide containing substance.  The pharmaceutically acceptable carrier in solid formulation can be a skin patch, many forms and types of which are known and used in the art. It is preferable that the composition be anhydrous.  The formulations appear to improve the fluorescence produced after exposing treated skin to activating light, as compared with the fluorescence produced with ALA in a fluid carrier.  In particular, the pattern of fluorescence is more even and uniform over the area of application than with topical creams or salves and may provide increased fluorescence.

Title: Pinned unitary bearing seal
Inventor: ORLOWSKI DAVID C
IPC: F16J15/447
Filed: 1996-05-06
Abstract: A mechanical labyrinth seal for rotating shafts having first and second ring members. The first ring member, includes a series of annular axially extending grooves and flanges. The second ring member is adopted for insertion into said first ring member with a plurality of complimentary inwardly extending flanges and grooves to form a well known labyrinth seal. There is a slot or channel through the labyrinth or maze connecting the exterior atmosphere to the interior of the seal assembly. The second ring member is adapted to rotate with the shaft and includes an annular recess near the shaft and inwardly toward the housing. There is a plurality of radial holes drilled in the first ring member to be opposite the recess in said second ring member and a plurality of pin members are inserted into the holes in said first ring member and are inserted into the recess of said second ring member. The recess being slightly larger in axial direction than the pin members. Thus, the seal permits axial movement of the shaft while maintaining the labyrinth seal integrity and during a predetermined amount of movement, and upon reaching the limit of said movement, the pins accommodate the axial thrust of the shaft movement. The pins are made of a material having natural lubricity and have only point contact with the walls of the recess, thereby reducing the amount of friction and wear in absorbing the axial thrust.
