Filed: 1996-11-04
Abstract: A packaging tape applicator for automatically applying packaging tape to groups of juxtaposed containers travelling along a conveyor comprises a gate mechanism movable between a holding position and a delivery position, for apportioning a continuous supply of individual containers into consecutive groups. Indexing means move along the conveyor in synchronized relation to the gate mechanism such that the indexing means are disposed in separating relation one between each consecutive pair of groups of juxtaposed containers. First and second packaging tape applicator mechanisms are positioned on opposite sides of the packaging tape applicator to apply first and second lengths of packaging tape to the groups of juxtaposed containers. First and second cutting mechanisms move in synchronized relation to the indexing means to cut the packaging tape, thereby separating the taped groups of juxtaposed containers one from another. A container packaging system is produced, wherein a plurality of like-size containers are secured together in a group by the first and second lengths of packaging tape. The method for automatically applying packaging tape to groups of juxtaposed containers travelling along a conveyor, comprises the steps of receiving a continuous supply of individual containers, apportioning the individual containers into groups, retaining consecutive pairs of the groups during travel along the conveyor, applying a first and second lengths of packaging tape to the containers, along opposed sides, and cutting the lengths of packaging tape.

Inventor: WILKINSON JOHN W
IPC: A47C27/08
Filed: 1995-02-21
Abstract: A pressure relief support system (10) utilizes a self-adjusting approach to maintaining generally constant pressure in fluid support bladders (70-76). A constant force, such as from a constant force linen spring (106, 108) or from a counterweight system (238), is applied directed to a fluid support bladder (182) or to a reservoir in fluid communication with such bladder. Plural self-adjusting arrangements tray be provided in a single device for fabricating a support body with sectionalized support. Such arrangements may be incorporated into mattress support systems (68) or into seating arrangements (538) or other alternative uses. By appropriately selecting system components, such as the amount of the constant force applied, the original volume of fluid to which the force is applied, and the reservoir size, pressure dispersion for a patient or supported object of any type may be controlled at a predetermined generally constant point.
Patent CA-2192275-A1 (CA)
Inventor: GOULET DOUGLAS P
IPC: B21D19/00
Filed: 1996-12-06
Abstract: The present invention comprises a tubing end fitting and a method of forming thereof wherein the fitting is formed out of the tubing itself. In a first step, the tubing end is compressed in a linear direction and shortened forming a first annular ridge extending around the tubing spaced from the end of the tube by a small tube portion. At the same time, the small tube portion diameter is reduced slightly. The small tube end portion is again compressed slightly in a linear direction initiating the formation of a second annular ridge spaced from the first annular ridge, while at the same time again slightly reducing the diameter of the remaining tubing end portion. In a third step the tubing end is again compressed in a linear direction completing the formation of the second annular ridge. In a fourth step the remaining tube end portion is flared outwardly forming an o-ring receiving groove between the second annular ridge and the tube end.

Title: Allosteric control of nuclear hormone receptors
Inventor: UMESONO KAZUHIKO
IPC: C07K14/705
Filed: 1995-12-28
Abstract: Heterodimerization is a common paradigm among eucaryotic transcription factors, though it remains unclear how individual monomers contribute to the overall transcriptional activities of the complex. The 9-cis retinoic acid receptor (RXR) serves as a common heterodimerization partner for several nuclear receptors including the thyroid hormone (T3R), retinoic acid (RAR) and vitamin D receptors. A strategy has been devised to examine the transcriptional properties of each receptor individually or when tethered to a heterodimeric partner. It has been found that the intrinsic activity of RXR is masked in RXR-T3R and RXR-RAR heterodimers. In contrast, a novel RXR-Nurr1 heterodimer described herein is highly responsive to RXR ligands, suggesting that different partners exert unique allosteric control over the RXR response. These findings establish a novel 9-cis retinoic acid response pathway and resolve the paradox as to how T3R, RAR and VDR contribute to distinct physiologic pathways while sharing a common RXR subunit.
