Abstract: The present invention provides a novel method of rendering a wallboard water-repellent comprising applying to the wallboard a water-repellent composition comprising a hydrogen siloxane component and a high molecular weight silicone.

Abstract: A drum assembly for the collection and disposal of hazardous waste includes an enclosure with an access hole for collecting the waste. After the waste has been collected, the drum is opened and an insert is positioned to cover the access hole. The drum is then closed to form a sealed container.

Abstract: A metal drum and the method of making the same having a detachable lining removable therefrom after a first use to allow for the reuse or recycling of the drum.

Abstract: A fiber drum and the method of making the same having a detachable lining fabricated therewith but removable therefrom after a first use to allow for the reuse or recycling of the drum.

Abstract: A collapsible, fiber, bulk container which is made-up of a plurality of sidewalls joined by connectors to form a tubular body. The body is closed off by top and bottom members telescopically engaging said body. The bottom may be reinforced by a strut member to insure that the bottom does not warp and collapse. A reinforcing strap is also secured around the body.

Abstract: A fiber drum with an integral skid is made by providing a lower skirt on a drum body. The skirt has cutouts for engagement by mechanized drum handling apparatus. The drum may also include an upper skirt cooperating with the lower skirt to maintain several drums aligned vertically for stacking.

Abstract: A barrel or drum, preferably of fibre, with metal chimes responsive to longitudinal compressive forces is provided. The compressive forces urge a diagonal flange of the chimes towards the horizontal thereby expanding the outer circumference of the flange of the chime. The outer circumference of the flange of the chime has a looped or tear-drop shaped high strength hollow beam construction so as to increase the stiffness or "stretch resistance" of the flange.

Abstract: A barrel or drum, preferably of fibre, with metal chimes responsive to longitudinal compressive forces is provided. The compressive forces urge a diagonal flange of the chimes towards the horizontal thereby expanding the outer circumference of the flange of the chime. The outer circumference of the flange of the chime has a rectangular high strength hollow beam construction so as to increase the stiffness or "stretch resistance" of the flange.

Abstract: A vehicle leveling strut of the type having a direct-acting hydraulic shock absorber provided with a reciprocable piston rod having a dirt shield mounted thereon. A tubular rolling diaphragm member secured at one end to the shock absorber and to the opposite end to the dirt shield and defining therewith a variable volume chamber adapted to be selectively pressurized and de-pressurized for controlling the distance between the sprung and unsprung portions of an associated vehicle. Located interiorly of the pressurizable chamber and concentrically positioned between the shock absorber and fixedly mounted to the dirt shield is a generally tubular support member upon which is mounted at least one pair of electrical coil windings for sensing changes in the electromagnetic field of each coil winding.

Abstract: A self locking cover/bottom for a fibre drum includes substantially perpendicular projections with inwardly tapered portions which, when in registry with notched portions in the fibre shell sidewall, engage the notched portions (which can bend inwardly) such that an airtight seal can be formed for the drum. An optional feature is the provision of a channel in the bottom to accommodate a tine of a fork lift truck.
