IPC: C12Q1/68
Filed: 1996-03-26
Abstract: The present invention provides novel assay methods for identifying compounds that may have both estrogen agonist and antagonist properties. In particular, the assay use cells comprising promoters having an AP1 site linked to a reporter gene. Compounds capable of inducing or blocking expression of the reporter gene can thus be identified. The compounds may be further tested for the ability to modulate the standard estrogen response, as well.

Title: Lid dispenser with dial adjustment and pivoting access door
Inventor: GUNDERSON JEFFREY E
IPC: B65G59/10
Filed: 1997-10-10
Abstract: The lid dispenser of the present invention has four rods which extend from the front to the rear and which hold the lids thereon. The rods are connected at the front to individual lid dispensing pagers, and at the rear to arcuate tracks in an adjustment wheel. The front pagers are also mounted in an adjustment wheel with arcuate tracks. Both adjustment wheels have serrated or ridged cylindrical edges, which allow the click-positioning of the wheels at a desired position to force the rods and pagers into an evenly spaced radial position. Three plastic claws are flexibly supported on a support member which is mounted for front-to-back movement on cover guide rods. Each claw member is connected by flexible bands to positionable fasteners which are fixed in radial slots in the support member which allow some radial movement of the claws as they engage a cover.  By use of such a dispenser in convenience stores and the like contact bycustomers with lids other than those dispensed is avoided.

Title: Composite rock bit seal
Inventor: KYKER G STEVE
IPC: E21B10/25
Filed: 1997-10-07
Abstract: A high performance rock bit journal seal is formed from a composite material comprising an elastomeric material and a nonelastomeric polymeric material. The polymeric material is preferably in the form of fibers woven into a sheet. The elastomeric material includes at least one lubricant additive. The composite 'seal' material comprises a number of repeating sheets of polymeric fabric that are bonded together with the elastomeric material. In one embodiment, the seal includes a body formed entirely from the composite material, in which case both the static and dynamic seal surfaces are the same. In another embodiment, the seal includes a first body portion formed from the composite material, and a remaining body portion formed from a noncomposite elastomeric seal material. Seals formed from the composite seal material display enhanced wear resistance, reduced coefficient of friction, and improved high-temperature stability and endurance when compared to noncomposite seal materials, thereby both extending the useful life of seals formed therefrom and of rock bits that employ such seals.

Title: Universal, energy-absorbent trailer hitch
Inventor: GULLICKSON RUSSELL C
IPC: B60D1/50
Filed: 1997-12-15
Abstract: The present invention features an energy-absorbent, hitching mechanism for towing trailers and other vehicles by pickup trucks or other tow vehicles. This is a mechanism of the universal type, in which energy absorption is achieved for all transverse and orthogonal forces, including force vectors in the vertical, lateral and longitudinal axes, i.e., the X, Y and Z axes of movement. The hitching mechanism has a housing for receiving a hitch ball that is attached to a tow vehicle. The ball is free to move within a chamber of the housing, subject to cushion forces described below, in any orthogonal direction, i.e., along the X, Y and/or Z axes. The housing chamber contains an energy-absorbent, dome-shaped pad that cushions the hitch ball. When the ball presses against the pad from any direction, the energy of any transverse force is absorbed by the pad, which expands into at least part of the housing chamber. A slide bar that is supported by the housing engages the neck portion of the ball, anchoring the ball for movement within the padded housing chamber. The slide bar is locked against slidable movement by a spring-biased locking pin, with the spring-biasing forcing the pin to seat within a detent hole in the housing, after it has passed through the slide bar. The locking pin is pulled upward against the biasing to release the slide bar, which in turn can be slid outwardly to release the shank of the hitch ball.

Abstract: The VRC is applied to a regeneration process, whereby the condensed water generated and a concentrated solution sent out from a regenerator are used as heat sources. When a dilute solution is preheated, the preheat quantity of the dilute solution increases to cause a performance coefficient of a heat pump to be improved. During heating, the concentration of the solution is increased by utilizing the absorbed liquid cooling heat for the room heating operation, and storing a part of regenerated cooling liquid medium, whereby the heat pump can be used for both the room cooling and room heating purposes.

Abstract: A shaft engageable with the reciprocative component of a voice coil actuator for selective translational projection of the shaft from the actuator includes a proximal section, an intermediate section, and a distal section. The proximal section is engageable with the reciprocative component of the actuator. A proximal connector, defined by a groove in the shaft between the proximal section and the intermediate section, is deformable in response to a force applied against the shaft distal to the proximal connector to substantially isolate the reciprocative component of the actuator from the force. Likewise, a distal connector defined by a groove in the shaft between the intermediate section and the distal section is similarly deformable in response to a force applied against the shaft distal to the distal connector, tosubstantially isolate the reciprocative component of the actuator from the force. Additionally, the shaft includes a lumen that extends from a proximal end to a distal end of the shaft. A vacuum source can be connected in fluid communication with the lumen for selectively creating a partial vacuum at the distal end of the shaft for holding components during the automated assembly of a product.

Patent CA-2246755-A1 (CA)
Inventor: SUBOTICS GYULA
IPC: F24J3/08
Filed: 1997-02-10
Abstract: The invention concerns a method and device for heating and cooling buildings.  During heating for cooling, the air heated by geothermal heat energy and supplied from the subterranean layers is circulated at least in the air duct of a heat-insulating air-circulation system (11), which is preferably provided with an inner heat-insulating air gap, an air duct and an outer heat-insulating air gap and, from the room interior, covers the walls (8, 9), delimiting the outer environment and other unheated rooms, and ceiling parts (4) of the room to be heated or cooled. At the same time, the outer ambient temperature (tk) is continuously measured by a thermostat (48) mounted outside the building. When the condition t1  tk - 1 ~C is satisfied, t1 being the temperature of the air circulating in the air duct, during heating, the air circulation is interrupted by means of the thermostat (48) and further heating of the interior (19) to a desired temperature, if necessary, is ensured by means of additional heaters which are preferably associated with the room. In contrast, when the room is cooled, the air, which is maintained at a given temperature by geothermal heat energy, is made to circulate when the temperature, which is continuously measured by means of a thermostat (47) disposed in the room, exceeds a given value. The air circulation is interrupted when the room temperature measured drops below a given value. The invention further concerns a heat-insulating wall covering which forms the heat-insulating air-circulation system according to the invention and comprises parquet-like plastics elements which can be joined to one another.

Title: Fast extraction of program specific information from multiple transport streams
Inventor: CUCCIA DAVID
IPC: H04N5/44
Filed: 1997-12-24
Abstract: A digital TV receiver suffers from latency when a channel change is made to a program in an other than the currently accessed transport stream (TS). That is because the transport decoder (202) must first acquire and decode the Program Specific Information (PSI) from the transport stream, such as the Program Association Table and Program Map Table. In accordance with the invention, a pre-decoder (203) is successively coupled to the other transport streams through a cross bar switch (204) to extract the PSI from said other streams and create a map of channels.
