Abstract: ABSTRACT OF THE DISCLOSURE An improved bearing for use in a ball and socket joint is disclosed.  The bearing is generally cylindrical in shape, having a recess formed in one end thereof.  The recess defines a semi-spherical bearing surface adapted to engage and support a head portion of a ball member of the joint.  A plurality of lubricant passageways are formed through the bearing.  Each of the passageways extends axially from the semi-spherical bearing surface to an annular channel formed in the opposite end of the bearing. A plurality of grooves are also formed in the opposite end of the bearing.  The grooves extend radially inwardly from the channel to a central recess formed in the opposite end of the bearing.  The channel functions as a reservoir for lubricant, thereby permitting the joint to be used without frequently re-injecting lubricant therein.  An annular bead is formed about the circumference of the channel to provide a seal which prevents lubricant from escaping from the joint.

Title: Air curtain fume cabinet and method
IPC: B08B15/02
Filed: 1990-11-22
Abstract: An air curtain fume cabinet, in which an air curtain jet is directed across the face opening to an exhaust duct. Sufficient flow is exhausted at the exhaust duct to swallow (i) the entire air curtain jet, plus (ii) all of the air which the jet entrains from outside the face opening, plus (iii) a substantial additional amount of air.  This greatly increases the velocity of air moving into the curtain at its  top,  beyond  the  normal  entrainment  velocity,  and prevents spill-back of jet air to the outside even with substantial crosswinds.   Preferably the ratio of exhaust flow to jet flow is between 2 and 3 for a jet height to jet thickness ratio of up to about 15.  Preferably auxiliary air is supplied to the working space interior to replace air entrained into the jet from inside the working space.

Title: Epoxy modified polyols as dispersants for high styrene, high solids content polymer polyols
Inventor: HAYES JOHN E
IPC: C08G65/26
Filed: 1991-01-10
Abstract: Very low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of epoxy modified polyols as dispersants.      The epoxy modified polyols useful as dispersants may be made by one of three methods: (1) adding the epoxy resin internally to the modified polyol, (2) capping or coupling a polyol not containing an epoxy resin with such a resin, and (3) providing the epoxy resin both internally to the polyol and as a cap or coupler. Epoxy modified polyols having a hydroxyl to epoxy ratio of about 8 or less, made by one of these techniques, are superior dispersants and provide polymer polyols having higher styrene contents, and improved stability and viscosity properties.      In one aspect, the epoxy modified polyols contain a significant amount of high molecular weight polyol adducts; generally from about 5 to about 30 wt.% of materials having a GPC molecular weight of greater than 100,000: and at least greater than 80,000. Base polyols unmodified with an epoxy resin are used to make the polymer polyols.
