Title: Cyclic aryl ethers, thioethers and amines, and method for preparation
Inventor: MAY LESLIE J
IPC: C07D323/00
Filed: 1999-01-20
Granted: 2005-04-12
Abstract: Cyclic aryl ethers, thioethers or amines, and methods for synthesis are disclosed. These cyclic aryl compounds are synthesized by combining a first dinucleophile with a substituted benzene metallized electron-withdrawing complex, having halo or nitro substituent groups, to form a linear bimetallized aryl compound. The linear bimetallized aryl compound is then reacted with a second dinucleophile to form a cyclic bimetallized aryl compound. The metallized electron-withdrawing moieties are then removed from said cyclic bimetallized aryl compound by photolytic demetallation to form a cyclic aryl compound having the formula   wherein:      X1 and X3 are the same or different and each is a alkyl, heteroalkyl, heterocyclic or aromatic group having up to 6 conjugated rings, optionally substituted;      X2 is benzene n1 and n3 are the same or different and each is O, S or N; and n4 is H or lower alkyl.

Abstract: A device is provided for compensating process and operating parameters variations in a CMOS integrated circuit. The device comprises means for generating a first and a second compensation signals which depend on quality indexes of the fabrication process of the P and N transistors of the integrated circuit and on the operating temperature, and which are capable of compensating deviations of the controlled quantity from the desired value, due to the deviation of the quality indexes and temperature, respectively, from a typical value which would originate the desired value for the output parameter. The compensating device also can be implemented in the form of CMOS integrated circuit, preferably jointly with the device to be subjected to compensation.

Title: Water and wastewater treatment system and process for contaminant removal
Inventor: STEPHENSON ROBERT JOHN
IPC: C02F9/06
Filed: 2000-02-08
Granted: 2003-01-14
Abstract: A system and process for removing contaminants from water and wastewater, where the water or wastewater is transformed into purified water that can be discharged to the environment. Wastewater is transported through several stations for purification, including an electrochemical cell. The purification process begins by sending the wastewater to a classifier through an in-line basket strainer. The wastewater stream in the classifier is drawn through a solid-liquid hydrocyclone, which returns the solids to the classifier and sends the remaining liquid to feed tanks. Contaminants that float are removed from the wastewater by skimming from the surface of the feed tank. The wastewater underflow from the feed tanks is pumped directly to the electrochemical cell where it enters into the bottom of the cell, and exits from the top of the cell. The discharge, including coagulated solids, hydrogen gas, and oxygen gas, is mixed with a polymer as well as compressed air just prior to entering a static in-line mixer. The resulting mixture flows past a vertical vent pipe to a flotation cell. The underflow of the flotation cell, which is substantially free of coagulated solids, flows by gravity to a settling tank where any remaining solids sink to the bottom. The solid-free liquid (water) exits the settling tank over an overflow weir and is pumped through a plurality of bag filters and finally through a polymeric filter to remove remaining contaminants.

Abstract: A multichamber container such as a multichamber tube or multichamber pump can deliver the contained products in varying arrays by the use of container shoulders of different channel configurations. The container body remains the same with chamber dividing walls (12, 22, 32, 52) extending from the container base to the container shoulder. The container shoulder attachment to the container walls and to the chamber dividing walls can remain essentially the same. Within the shoulder, channels direct the flow of each product so that it has a number of arrays from an A/B/A sandwich to axial arrays to semiconcentric arrays to fully concentric arrays. The channels that are a part of the shoulder will direct the product from each chamber to be dispensed in a single stream or multiple streams. Also, the streams can be shaped to many different shapes by the shape and the arrangement of the channels in the shoulder.

Patent CA-2311345-C (CA)
Inventor: HANNA EMMANUEL A
IPC: A47K3/12
Filed: 2000-06-13
Granted: 2008-10-14
Abstract: The present invention provides an ambulatory assistance device such as a grab bar or the like which pivots between a non-in-use and an in-use position. The pivoting of the device is assisted by a torsion member acting between the base member and the body. The torsion device is selected so as to retain the body in its non-in-use position when placed in that position. The weight of the pivoting body of the present invention overcomes the force generated by the torsion member when the body is placed in the in-use position so as to retain that orientation. Moreover, the torsion member acts to assist the user of the device in counteracting the weight of the pivoting body member when the body member is moved between the non-in- used position and the in-use position.

Granted: 2006-12-12
Abstract: According to the invention the labels (22) are produced in a broad woven fabric (21) comprising ground warp yarn (4) and ground weft yarn (5) for a ground woven fabric (11), embroidery weft yarn (12) which forms a figure and code weft yarn (10) which forms a barcode, said yarn being distinguishable from the ground warp yarn only in a light outside the visible spectrum. In the broad woven fabric (21) several labels (22) are produced whose longitudinal sides (1) adjoin each other in the weft direction and remain unfolded and whose lateral sides (2) are adjacent to each other in the warp direction and can be folded. The embroidery weft yarn (12) and the code weft yarn (10) extend parallel to each other and at a distance from the longitudinal sides (1) so that the backs of the labels (22) are evenly covered and thus uniformly transparent.  The broad woven fabric (21) is cut along the lateral sides (2) into strips (25) each consisting of transverse labels (22) which are situated one behind the other in the warp direction. The labels (22) are then separated into individual labels by cuts along their longitudinal sides (1), which produces soft cutting edges (16) in the ground woven fabric (11) which do not irritate the skin.
