Abstract: A polymeric material comprised of (i) at least one random copolymer comprised of ethylene oxide and one or more other alkylene oxide(s) and (ii) at least one non-random polymer comprised of one or more poly(alkylene oxide)s has been discovered. Preferably, it is a polymer alloy. Alkylene oxide homopolymers or block copolymers may be the non-random polymer. In a related discovery, an adhesive material can be made by suspending (a) particles in (b) a matrix of at least one poly(ethylene oxide) copolymer of ethylene oxide and propylene oxide, or a combination thereof. The handling characteristics may be adjusted for different utilities (e.g., from runny oil to hard wax). Applications include use as adhesive, cohesive, filler, lubricant, surfactant, or any combination thereof. In particular, the hard materials may be used for cleaning or waxing.

Abstract: We describe the medical, dental, and surgical uses of modified poly(alkylene) materials which are fully resorbable after implantation into the body, and compositions formulated with such modified poly(alkylene) materials.

Abstract: A gear assembly for transmitting torque from one shaft to another comprises two intermeshing gears mounted on respective shafts. One of the gears comprises a hub member for receiving one of the shafts, a toothed annular member mounted for rotation with the hub member. At least one spring provided between the hub member and the annular member has stiffness capable of reducing torsional vibrations and noise induced during rotation of the gears by the eccentricity of at least one of the gears.

Abstract: Medical and surgical uses for random alkylene oxide copolymers have been discovered. Preferably, this is a biocompatible, non-metabolizable, non-toxic, and/or readily eliminated compound that has a viscosity which is adjustable for different utilities (e.g., from runny oil to thick grease). It is also preferable to formulate the compound as an anhydrous and/or flowable liquid before use or further formulation.

Abstract: A valve comprising a housing having an inlet and spaced therefrom an outlet, a passageway extending between the inlet and the outlet, and a mechanism located in the passageway for controlling the flow of a fluid between the inlet and the outlet, the mechanism including a valve assembly movable between a first open position spaced from a co-operating valve seat and a second closed position at which the valve assembly sealingly engages the valve seat, in which the valve assembly is biased towards the second closed position using a magnet-operated mechanism.

Abstract: A valve assembly comprising a housing having an inlet and space therefrom an outlet, means located in the housing for controlling the flow of fluid between the inlet and the outlet, said means including a main valve movable between a first relatively closed position and a second open position, said movement being controlled by a pilot valve assembly including a temperature sensitive member such that when the temperature in the fluid reaches a predetermined value the pilot valve is opened thereby allowing the main valve to move from said first to said second open position.

Abstract: An apparatus for separating a gas-liquid mixture into component parts having a coalescing filter mounted on a rotatable shaft. The gas-liquid mixture is directed to the coalescing filter in a generally radial inward direction relative to the shaft and the retained liquid is spun in a generally radial outward direction from the filter by centrifugal force associated with the rotation of the shaft and thereby the coalescing filter.

Abstract: A mine roof support comprises at least one hydraulically extensible chock leg connected at its upper end in articulated manner to a roof beam of the support, and connected at its lower end in articulated manner to a base member of the support, a pair of links each having bearing surfaces adapted either to embrace a common chock leg by bearing on opposite sides thereof or to bear on adjacent sides of a pair of spaced apart chock legs, one end of each link being pivotally attached to the base member at a pivot point located to one side of a diametral plane passing through the longitudinal axis of the chock leg on which the link bears, the other end of the link being located to the other side of that plane and being acted upon by a restoring ram adapted to displace the or each link about it or their respective pivot points, to restore the or each leg to its predetermined position upon release of the support from the roof, and also to resist tendency for the or each leg to become displaced from the predetermined
