The apparatus comprises a filtration system for cleaning up recovered fluid, a primary pump, an accumulator, a first manifold for fluid injection, a second manifold for fluid recovery, and a return conduit from the second manifold to the filter.

Abstract: Aggregates of cellulose-containing particles, such as particles of waste paper and optional other vegetation or waste particles are used as a carrier for additives such as insecticides, herbicides, fertilizers and nutrients. The particles permits a “timed release” of the additives. The particles can be employed as a building insulation to prevent infestations of roaches, termites, ant, or other insects in the building when they contain insecticides. The particles can also be employed to promote revegetation of denuded areas, such as highway right of ways when they contain fertilizers and nutrients.

Abstract: A device is disclosed which enables a scoped firearm owner to determine whether a scope has lost zero due to being moved or hit. A blank cartridge form is attached to a second scope by a bracket. To use, the rifle is first sighted in, then the blank cartridge form is inserted to the rifle chamber and the device is rotated around the chamber until a stop device protruding from the bracket touches the rifle scope. The rifle is then placed in a firm rest with the crosshairs of the rifle scope centered on a target at a known distance and the second scope then adjusted to indicate the same aiming point. If the owner is later unsure whether the scope has lost zero, a target can be set up at the same distance, the device again mounted to the rifle, and the two scopes viewed to determine whether the same impact point is indicated. If it is not, the rifle scope can then be adjusted to the spot indicated by the device scope.

Abstract: A gravity measuring instrument comprises a housing, a float, and proximity sensing means between the housing and the float. The housing defines a vertically oriented elongated chamber for containing a liquid. The chamber has an upper end and a lower end. The float is elongated and is positioned in the chamber. The float has an upper end and a lower end. A liquid partly fills the chamber and the float is positioned for free floating movement in the liquid in response to gravity variations. A proximity target is on the lower end of the elongated float and a proximity sensor is supported in immovable relation with the housing beneath the lower end of the elongated float. The sensor provides electrical signals representative of distance between the proximity sensor and proximity target. The design avoids large, upwardly facing, horizontal surfaces on the elongated float to reduce the possibility of erroneous gravity readings due to the accumulation of fluid droplets or dust on such surfaces.

The floatation collar has a longitudinal axia and is formed from a sidewall body having a longitudinally extending slit extending through the sidewall body. The slit enables the floatation collar to be transversely mounted onto the marine riser.

Abstract: To form a candle blank, a volume of hot liquid candle wax is injected into a generally cylindrical chamber having a length and a diameter. The hot liquid candle wax is then cooled and the length of the generally cylindrical chamber is reduced as the wax cools, so that the volume of the chamber remains substantially that of the volume of the shrinking wax. By operating in this manner, there is no room for a void to form. An apparatus to carry out the process comprises a block, a piston, a gate, a means to inject the wax, and a means to move the piston so that it follows the shrinkage of the wax as it solidifies. The block defines a generally cylindrical mold chamber for the candle blank. The mold chamber has a generally vertically positioned longitudinal axis, an upper end, and a lower end. The piston is positioned in the chamber to slide from the upper end to the lower end of the chamber. The gate is positioned at a lower end of the chamber.

Abstract: A method of facing a substrate comprises applying a plurality of facing bodies to a carrier in a pattern corresponding to the desired pattern of the bodies on the faced substrate. The carrier has holes positioned centrally with respect to each body. Each body has, on a contact face to be fixed to the substrate, spaced raised weld elements which serve to locate the contact face parallel to and spaced from the substrate. The carrier is applied to the substrate with the contact faces of the bodies facing the substrate and then each body is electrically welded to the substrate by applying a welding tip to the body through each hole. A gap remains between the contact face and the substrate. Finally, the bodies are brazed to the substrate and brazing material flows between the bodies and the substrate. A facing kit comprises a carrier strip with facing bodies adhered thereto, each having raised weld elements in the form of dimples or lines.
