Title: Method and apparatus for the production of tgf-beta and purified tgf-beta compositions
Inventor: PUNGOR ERNO JR
IPC: C07K1/18
Filed: 1990-09-10
Abstract: METHOD AND APPARATUS FOR THE PRODUCTION OF TGF-B ABSTRACT OF THE DISCLOSURE         Transforming growth factor B (TGF-B) is produced in relatively large quantities and at a relatively high purity by fermentation in a perfusion microcarrier reactor.  Conditioned media from the reactor is first treated to provide the active form of TGF-B and subsequently purified by cation exchange chromatography followed by hydrophobic interaction chromatography. Optionally, nucleic acids complexed with the TGF-B may be removed while the protein is bound to the cation exchange resin.  Purified TGF-Bl compositions have a specific activity above 107 U/ml.

Title: A particulate, absorbent, polymeric compositions containing interparticle crosslinked aggregates
Inventor: ROE DONALD C
IPC: A61F13/53
Filed: 1991-03-25
Abstract: Methods of producing particulate, absorbent, polymeric compositions comprising interparticle crosslinked aggregates. In the methods of the present invention, an interparticle crosslinking agent is applied onto precursor particles; the precursor parti-cles are physically associated to form a multiplicity of aggregates; and the interparticle crosslinking agent is reacted with the po-lymer material of the precursor particles of the aggregates, while maintaining the physical association of the precursor particles, to form crosslink bonds between the precursor particles to form interparticle crosslinked aggregates. The interparticle crosslinked aggregates are formed to such an extent that the mass average particle size of the polymeric composition is at least about 25 % greater than the mass average particle size of the precursor particles.

Title: Constrained vane compressor with oil skive
Inventor: HEKMAN EDWARD W
IPC: F04C18/344
Filed: 1992-10-06
Abstract: CONSTRAINED VANE COMPRESSOR WITH OIL SKIVE                 ABSTRACT OF THE DISCLOSURE         A constrained rotary vane compressor having a rotor-vane assembly within a stator often exhibits unwanted noise and vibration effects.  The present invention offers a design and method to decrease noise and vibration effects of such compressors by the incorporation of an oil skive formed in the interior wall of the stator.  The oil skive rids the vane tips of any excess liquid which may have collected on the rotating vanes, which otherwise may impact certain interior regions of the stator resulting in unwanted noise and vibration of the compressor.
Patent CA-2080152-A1 (CA)
Inventor: SWEENEY DEREK J
IPC: F02C7/28
Filed: 1992-10-08
Abstract: Abstract LOW-PRESSURE TURBINE SHROUD A turbine shroud is formed by a ring of butted shroud segments.  Each turbine shroud segment has a radially inwardly projecting annular flange which is seated on a radially outwardly facing surface of an annular tip of the outer shroud of the downstream nozzle stage.  This flange is free to slide axially relative to the annular tip during thermal expansion of the nozzle outer shroud in the axial direction.  Each turbine shroud segment has a spring seated thereon which urges the radially inwardly projecting flange toward the annular tip of the nozzle outer shroud.  Honeycomb material attached to the turbine shroud segment discourages the flow of hot gases through the gap between the flange and annular tip of the outer shroud of the downstream nozzle stage attributable to seam chording, thereby reducing the leakage of hot gas into the spaces between the shrouds and the outer casing.

Patent CA-2087215-A1 (CA)
Inventor: TEMPEL LORNE F
IPC: F16L57/00
Filed: 1993-01-13
Abstract: A weather protector for the end of a pipe section, e.g. for use in a pipeline, tends to prevent the ingress of snow and rain into the interior of the pipe.  The weather protector is made from a generally circular blank having peripheral tabs, a few  of  which  are  widely  circumferentially  spaced  and  are appreciably longer than the remaining tabs and extend over the edge of the pipe end.  The weather protector is placed in the interior of the pipe, the tabs forming a substantially continuous cylindrical rim portion that engages the interior cylindrical surface of the pipe.   The longer tabs position the weather protector in the interior of the pipe by overlapping the pipe end to prevent the weather protector from being pushed further into the interior of the pipe. The spacing between any neighbouring pair of longer tabs is sufficient that a pipe gripping element may grip the edge of the pipe without encountering any of the tabs so that the weather protector may stay in place at the pipe end even though it has been handled repeatedly.  The outermost circular surface of the weather protector is preferably water repellant.  A small hole may be provided in the circular area to relieve pressure differentials between the interior and the exterior of the pipe.   The exterior tab ends are preferably tapered  to reduce wind drag  during  transit.    The weather protector is preferably made of cardboard or similar disposable biodegradable material.

Filed: 1993-02-02
Abstract: The disclosure herein describes a light fixture for mounting to a ceiling,  wall or the  like which comprises a pot having a peripheral edge abutting the area adjacent a hole made in the ceiling or wall.  A hook and a bolt extending through appropriate openings in the inner wall and the side wall of the pot cooperate to secure the pot to the ceiling.  Rotating the bolt causes the hook to move into an abuting engagement with the rear surface of the ceiling, the latter thus being contacted, on the outside, by the peripheral edge of the pot and, on the inside, by that portion of the hook engaging the rear surface of the ceiling.

Abstract: A paint roller tray and lid having a seal for resealable air-tight mating of the tray with the lid. The lid has a paint roller handle holder so that when the lid is mated onto the tray the paint roller handle is detachably securable to the lid. The holder for holding a paint roller handle has a pair of resilient protrusions depending from the interior of the paint roller handle housing of the lid, the protrusions being in spaced apart relation so as to snugly receive therebetween a paint roller handle. The housing has contiguous sides extending upward from the upper surface of the lid and a roof extending between the contiguous sides. The protrusions depend from the roof into the housing, each of the resilient protrusions having therein a finger or thumb receptacle for insertion of a finger or thumb into the receptacle from the top of the housing whereby when a finger and a thumb are placed into the receptacles and a paint roller handle is detachably secured between the protrusions, the protrusions may be resiliently deformed so as to grip the paint roller handle between the protrusions.

Filed: 1993-02-23
Abstract: Abstract of the Disclosure An adapter (10) is useful to prevent formation of a static electrical charge on an outlet valve (V) during discharge of lading from a railcar on which the valve is installed.  A unitary member (12) has an inlet end (14) formed for attachment to the outlet valve, and an outlet end (16) formed for connection with a hose (H) into which discharged lading flows.  A passage (28) is formed in the member and extends from the inlet end to the outlet end.  The passageway is of an irregular shape at the inlet end of the adaptor.  It is of a generally circular shape at its outlet end.  The member is formed of an electrically non-conductive, resilient material so that it prevents the build-up of any static electrical charge as lading flows through the member.
