Inventor: SWIFT RONALD ALLEN
IPC: C11D11/00
Filed: 1995-02-24
Abstract: A process for making a detergent composition in form of agglomerates is provided. The process for making a detergent composition comprises the step of adding a paste mixture to a mixer/densifier wherein the paste mixture includes from about 1 % to 50 % by weight of a detersive surfactant system comprising at least about 30 % of a surfated suffactant selected from the group consisting of alkyl sulfates, alkyl ethoxy sulfates, secondary alkyl sulfates and mixtures thereof, and from about 1 % to 50 % of a hydrotrope selected from the group consisting of sulfyl succinates, xylene sulfonates, cumene sulfonates and mixtures thereof. The process also includes the steps of mixing at least about 1 % by weight of a detergency builder into the mixer/densifier, and agglomerating the paste mixture and the builder into detergent agglomerates which are substantially free of phosphates. The anionic surfactants in the detergent composition have significantly improved dissolution in aqueous laundering solutions, especially those kept at cold temperatures, i.e. 5 °C to 30 °C
Patent CA-2184854-A1 (CA)
Title: Universal socket device
Inventor: SCHUPP ANDREAS
IPC: B25B13/10
Filed: 1996-09-05
Abstract: A universal socket is described which is suitable for use upon a myriad of fastening means whereupon at least a plurality of pins are capable of longitudinal axial movement in concert and in conformity with contact with a workpiece. This result is achieved by the incorporation of a biasing mechanism on the pins which biases the pins in a normally extended position, but which permits movement to a second retracted position. In one embodiment, the cross-sectional area of the pins is decreased in either a linear or non-linear manner from the outer periphery to the center of the socket. In operation, as the workpiece is inserted into the socket, the pins are moved in alongitudinal axial direction from their normally extended position to the secondretracted position in conformity with the shape of the workpiece. Upon the application of a torque force to the closed end of the socket fitted with a drive means, the workpiece is either moved clockwise or counterclockwise depending upon the nature of the operation to be performed, i.e., tightening or loosening. Upon removal of the workpiece, the pins return to their original extended position due to the biasing mechanism, typically being a spring positioned around a reduced diameter uppermost end of the pins. In one configuration of the pins, accommodation is made for larger multi-sided workpieces than would normally be expected to be inserted into the socket based on the available surface area of the pins through the incorporation of triangular shaped free space within the socket adjacent to the pins. This permits larger sized 4-sided and 6-sided nuts and bolts to be effectively removed or tightened for example.

Inventor: LI SHIH-LIN
IPC: G01B3/10
Filed: 1997-06-20
Abstract: A coilable tape blade is disposed in a housing with a distal end having a hook projecting from an aperture. A positive locking mechanism is mounted on a frontal peripheral side of the housing and is operable for applying a positive lock on the tape blade when the tape blade has been extended from the housing. A measurement of a work piece can be determined when the tape blade is locked in an extended position. A decelerating mechanism is mounted on the bottom of the tape measure. The decelerating mechanism comprises a lever, a spring and an anvil. When the positive locking means is released, the decelerating mechanism can be used to control the speed at which the tape blade is retracted into the housing, thereby preventing damage to the distal end of the tape blade and the hook. The deceleration of the automatic retraction of the tape blade into the housing is accomplished by pressing the lever at its pressure point. The lever has two extensions that engage the tape blade with the anvil, and temporarily stops the retraction of the tape blade. The whole tape measure fits comfortably within the user's grip. The user's thumb is positioned on the push button of the positive locking mechanism and the user's fingers are positioned on the lever.

Title: Recycling of mineral fillers from the residue of a paper deinking plant
Inventor: YOUNG TRUDY DIANE
IPC: D21H17/67
Filed: 1996-03-14
Abstract: A method of recycling mineral pigments contained in the waste produced from the deinking of wastepaper. The deink residue is heated in an oxygen-containing atmosphere to a temperature sufficient to completely oxidize all the organic hydrocarbons present. Combustion causes a chemical reaction to occur, so that the original pigments contained in the deink residue are converted to new, stable mineral forms. The ash from the combustion is primarily a mixture of Gehlenite, Anorthite and Perovskite. The ash containing the mixed mineral phases is added to a reactor in which carbon dioxide gas is bubbled through an aqueous slurry of calcium hydroxide so that precipitated calcium carbonate (PCC) is produced. Because the mineral phases in the ash contain calcium as part of their crystal structure, the PCC will precipitate and grow on the ash particles. This results in a "recycled" PCC pigment containing an ash "core".
