Title: Riser device for creating an elevated structure for artificial landscapes
Inventor: FULTON C DWAYNE
IPC: A63H18/04
Filed: 1998-07-30
Granted: 2007-05-29
Abstract: A structure is provided for creating an elevated subroadbed for an artificial landscape. The structure includes a flexible riser section of a given length that has a generally planar bottom. The riser section also has a generally planar top extending and supported parallel to the bottom so that the height of the section is consistent along its entire length. The riser is provided with first and second side walls, which each have a series of channels that extend into the riser in spaced apart relation. The channels allow the riser to be positioned in a radius. The top forms an elevated surface that enables low- lying areas to be more easily created on the artificial landscape below the elevated surface. A flexible incline section is also provided for creating a roadbed for an artificial landscape. The incline section has a top that extends at an angle relative to its bottom so that the section increases in elevation from one end to the other. Further, the incline section has channels formed therein which allow it to be flexed in either direction. A first flexible incline section may be provided that rises from a base to a higher elevation. A second incline section is provided which starts from the highest elevation of the first section and further increases in elevation. The second incline section and the first section can be placed in abutting relationship to form a roadbed having a continuous grade. Subsequent sections may be provided which further increase the elevation achieved.

Abstract: A shock-absorbing telescoping tool handle (2) is disclosed having tubular, larger diameter proximal and a smaller diameter distal portions (4, 6). An internal spring ( 14) between the handle portion is compressed when the handle portions telescope toward each other.      Guide mechanism (26, 28) in the handle portions limits the extent of sliding motion between the handle portions and prevents relative rotation of the handle portions. One or more wipers (40) in the handle portion wipes away any snow, water or debris on the distal portion which could potentially enter the spring area.

Abstract: The invention relates to an aerated flooring system for use in athletic arenas or gymnasiums. The flooring system includes a top layer that provides a surface for the activities to be conducted on the floor. The system also includes at least one ventilation device. The ventilation device covers an air flow shaft within the flooring system, helping to prevent debris from falling in the air flow shaft, but allowing air to flow through the ventilation device. The ventilation device allows air to ventilate out of the flooring system. A support layer below the top layer provides support to the flooring system. A ventilation layer below the flooring is sized to allow air movement through the layer. The air flow shafts allow air to travel from the ventilation layer to the ventilation device. A base is below the ventilation layer and provides support for the flooring system above. A blowing device is controlled by a computer system that monitors the system using sensors. The blowing device can provide air circulation through the flooring system by creating air flow through the ventilation layer, through the air flow shafts, into the ventilation device, and out the flooring system. The aerated flooring system can also be adapted to existing conventional flooring systems without the need to tear up and remove the old flooring.

Abstract: An apparatus for processing materials which are highly corrosive while in a thixotropic state, for example aluminum. The apparatus includes a barrel which is adapted to receive the material through an inlet. In the barrel, the material is heated and subjected to shearing, forming a highly corrosive, semi-solid slurry which is discharged from the barrel through a nozzle. The barrel is constructed with an outer layer of a first material and an inner layer of an Nb-based alloy which is bonded to the outer layer. Positioned within the passageway of the barrel is a screw, the rotation of which operates to subject the materia l to shearing and move the material through the barrel. The screw is constructed with an outer layer of the Nb-based alloy that is molecularly bonded to an inner core of a different material. The Nb-based alloy is resistant to the corrosive effects of the material being processed.

Title: Instant-on cooking device controller
Inventor: HARTER DAVE
IPC: A47J27/62
Filed: 1997-06-03
Granted: 2005-08-16
Abstract: A unique instant-on feature for a cooking device that allows microprocessor (26) control of the device after a period of idling. When activated, the instant-on enabler switch (16) sends a signal to the microprocessor (26), which checks an internal clock to determine the amount of time the device has remained idle since the last cook cycle. This information is sent back to the instant-on enabler switch (16), which then selects among an appropriate array of cooking times. These times, longer than the initial pre-set cooking time, are based on testing and compensate for the degree of heat zone stratification in the cooking medium or surface caused by the extended idling. The instant-on enabler program immediately supplies additional heat to the cooki ng surface upon activation cooking cycle or operator input, allowing the maximum time for the cooking surface to reach proper cooking temperature.

Title: Osmotic delivery system with semipermeable plug
Inventor: AYER RUPAL

Granted: 2009-10-27
Abstract: Osmotic delivery system semipermeable body assemblies that control the delivery rate of a beneficial agent from an osmotic delivery system incorporating one of the semipermeable body assemblies. A semipermeable body assembly or plug includes a semipermeable body which is positionable in an opening of an osmotic delivery system. The semipermeable body has a hollow interior portio n having a size selected to obtain a predetermined liquid permeation rate through the semipermeable body. Because the beneficial agent in the osmotic delivery system is delivered at substantially the same rate the osmotic agent imbibes liquid which has permeated through the plug from a surrounding environment, the liquid permeation rate through the plug controls the delivery rate of th e beneficial agent from the osmotic delivery system. The liquid permeation rat e through a semipermeable body may be varied to control the delivery rate of beneficial agent from an osmotic delivery system by changing the thickness of the semipermeable body or by changing an amount of surface area of the semipermeable body that is exposed to liquid when the osmotic delivery syste m is located in a liquid environment of use.
