Abstract: A modular tool assembly including a tool base configured to releasably secure a modular tool arrangement in a fixed relationship relative to a mounting surface. The tool base includes an upper housing portion and a lower housing portion having a mounting seal extending therefrom. The mounting seal cooperates with the mounting surface to define a vacuum pocket therebetween. A vacuum generating mechanism is configured to remove air from the vacuum pocket through an aperture in the lower housing portion. A modular tool attachment releasably engages a portion of the tool base to secure the modular tool attachment to the tool base. The modular tool attachment can include a self leveling laser leveling device having a laser light source mounted within a housing to project an alignment beam through an opening in the housing to denote a reference plane along the mounting surface.

Abstract: The present invention provides a sample chamber for a centrifugal permearmeter for testing permeant conductivity of a porous sample, the sample chamber comprising a rigid outer sleeve; a resilient inner sleeve mountable over the sample and within the rigid outer sleeve; fluid inlet means for introducing fluid between the inner and outer sleeves; sealing means acting between the inner and outer sleeves for maintaining the fluid therebetween; a porous top member for mounting over a top face of the sample and supplying the permeant to the sample, the top being movable with the sample to maintain a radially outward permeant force on the sample as the sample is being spun in the centrifugal permeameter; a permeant supply for supplying the permeant to the porous top; and, a permeant accumulator for receiving and accumulating permeant which has passed through the sample.

Abstract: Apparatus for removing a liquid (2) containing suspendible solid matter from a tank (1) comprises a plurality of nozzles (47) located at the lower region of the tank. A pump (10) removes the liquid and ejects it through the nozzles (47) to cause resuspension of settled solid matter. When sufficient resuspension has occurred, the tank (1) is emptied by opening a valve to remove a portion of the liquid being transferred to the nozzles (47). The nozzles (47) are arranged as oppositely facing pairs ofjet nozzles at the lower end of a rotatable vertical pipe (46). The pump (10) is suspended by a cable (13) connected to a drum (19) which can be rotated to raise or lower the pump. A pump outlet (12) is connected to a flexible hose (27) which is wound around the drum (19) or around a separate drum (110). A movable containment flask (14) houses the drum (19) and accommodates the pump (10) when withdrawn from the tank (1).
