Title: Stabilized, high solids, low viscosity smectite slurries, and method of preparation
Inventor: PAYTON JAMES
IPC: D21H17/68
Filed: 1994-09-23
Granted: 2001-05-29
Abstract: An aqueous slurry of smectite clay of elevated solids content, comprising an aqueous solution or emulsion of at least 0.2 % by weight of said slurry of a salt of a low molecular weight amine salt, in which is dispersed from about 10 to 47 % by weight of the slurry, of a smectite clay. The amine salt is effective to prevent the smectite from swelling appreciably, whereby the slurry can be shipped and stored without creating a gelling problem. The inhibiting or suppressing effect of the amine salt on the swelling of the clay and on gelling of the slurry is reversible upon subsequent dilution with water, thereby facilitating use of the smectite in typical applications, as a retention aid in paper making, or as a viscosifer.

Title: Communication system resource allocation method
Inventor: AHLENIUS MARK TODD
IPC: H04J1/00
Filed: 1995-09-05
Granted: 1998-10-06
Abstract: A method of allocating communication resources in a com-munication system includes retrieving (404) from the communica-tion system a communication system resource allocation.  An allo-cation parameter is set to an initial value (406) and communication resources are randomly selected from cells (414).  A candidate com-munication resource is either swapped or mutated for the selected communication resource (416) and the system performance is eval-uated with the candidate communication resource (422).  If system performance is improved the candidate resource is retained as part of the allocation (426, 432), or if system performance is degraded, the candidate resource is retained with a probability (428, 432). The steps repeat while the allocation parameter is valid (408), and upon completion a new communication resource allocation is downloaded to the communication system (410).

Abstract: A dental implement designed to be retained for reciprocating movement by the sleeve member of a dental handpiece.  The dental implement is comprised of a flat dental tool having a flat blade portion and a flat shank portion. The flat blade portion can also be formed with a triangular or arcuate cross section while retaining the flat shank portion and the blade edges can be straight or have a saw-tooth configuration.  A removable tool holder has a slot to receive the dental tool and an outside cylindrical shape complementary with the bore of the sleeve member. Forces applied to the tool holder control the displacement of locking protrusions on the tool shank to selectively permit the tool to be driven in a reciprocating movement with or without rotation and to be removed entirely from the sleeve member.

Abstract: Disclosed is a process for making soft tissue paper which includes providing a dry tissue web and then applying a sufficient amount of a functional-polysiloxane softener compound to the dry web. The softener application process includes the steps of mixing a functional-polysiloxane compound with a suitable nonvolatile diluent, such as a nonfunctional-polysiloxane, forming an emulsion containing the functional-polysiloxane compound and nonvolatile diluent using a volatile solvent, such as water, and surfactant emulsifier, applying the emulsion to a heated transfer surface, evaporating the volatile solvent from the emulsion to form a film, and then contacting the dry tissue web with the heated transfer surface. Preferably, the tissue web is dried to a moisture level below its equilibrium moisture content before application of the functional-polysiloxane material. The process may further include the steps of applying an effective amount of a surfactant material to enhance softness and or wettability control; and or an effective amount of a binder material such as starch, for linting control. and/or to contribute tensile strength to the tissue paper.
Patent CA-2185996-C (CA)
Inventor: OFFER HENRY PETER
IPC: B23K9/02
Filed: 1995-04-19
Granted: 2007-03-20
Abstract: A process for providing a significant improvement in the detrimental tensile residual stress condition on the root side of welds, especially on the inside wall of piping welds. The method uses a high welding torch travel speed (10 inches/min), especially on the last one or two cap passes. The process relies on the limited thermal heat sink capability of the pipe wall and nearly completed weld joint itself to generate a significant through-wall temperature gradient, and therefore a sufficient through-wall stress gradient during the welding. This stress gradient results in metal plasticity and permanent strains, and therefore a reduction in the magnitude of the final residual stress or, preferably as conditions allow, a reversal in the direction of the stresses from tensile to compressive. The method can be used as a welding process or as a heat treatment. In the case of heat treatment, the far surface of the weld joint is heated without fusion of the material making up the far surface.

Abstract: An improved replacement ladder rung/pulley construction is disclosed wherein a rotatable rod, mounted on bearings and extending substantially completely from one side of the ladder wall to the other, is located within the rung. The rung has a cutout portion proximate its center, which allows a rope to be passed therethrough and over the rotatable rod. The rod thus functions as a pulley and obviates the possibility of the rope sliding off and becoming jammed if the pulling force is exerted from one side or the other.

Title: Analyte detection from steady-state luminescence lifetime
Inventor: ZUCKERMAN RALPH
IPC: G01N21/64
Filed: 1995-04-19
Granted: 2007-09-04
Abstract: Methods and apparatus determine analyte concentra- don in vivo and in vitro by the steady state determination of luminescence lifetime. A fluoro-phore that is quenched by the analyte is free to undergo Brownian rotation. The fluoro-phore (12) is irradiated with continuous linearly po- larized light (24). Emitted luminescence is resolved into vector components parallel and perpendicular to the plane of polarization of the excitation light (36, 38). A math- ematical function is employed which relates the lumines- cence anisotropy to quencher concentration. For analytes which do not quench excited staves, a known quantity of the analyte is conjugated to a quencher molecule or energy transfer acceptor, and a competition reaction is set up in which labelled and unlabelled analytes compete for sites on a labelled carrier molecule. An empirically determined mathematical function is employed which relates lumines- cence anisotropy at the carrier label emission band to ana- lyte concentration.

Title: Seismic data acquisition system
Inventor: HARMON JERALD L
IPC: G01V1/22
Filed: 1998-05-15
Granted: 2007-01-09
Abstract: A seismic data acquisition system is featured that utilizes a series of nearly identical seismic shots (SISS) to synchronize and to communicate with novel data acquisition units (NDAU) located in the field. Each SISS seismic shot is carefully timed to provide synchronization to each NDAU, and to allow the NDAU to correct for the time drift of its internal clock. Further, each NDAU is programmed with a number of menus, which are used to interpret the seismic shots received from a seismic source. Thus, communication from a central or headquarter site to each NDAU is facilitated, allowing for a change in production schedule and other variables. In addition, the disclosed seismic data acquisition system features movable SISS source sites and overlapping production and SISS shots.
