Title: Collapsible apparatus for compressing packing material in liquid chromatography columns and methods of use
Inventor: FAN CHIKO
IPC: B01D15/22
Filed: 1997-02-28
Abstract: Longitudinally collapsible apparatus for compacting packing material within a tubular liquid chromatography column. The apparatus includes a first support member, a second support member and a movable support member. The movable support member is releasably connectable to the second support member for support thereby. When released from the second support member, the movable member is adapted to ride on guide members extending between the first and second support members. A compression mechanism is supported on the movable support member to move therewith to a longitudinally collapsed position for the apparatus. The compression mechanism comprises a reversible drive for an axially movable rod carrying a movable piston. With the movable support member secured to the second support member, the piston of the compression mechanism is movable in an end of the tubular column when the column is supported on the first support member. Movement of the movable piston within the column axially compresses a column packing material as the piston is driven towards an opposite end of the column. The piston also is releasably connectable to the tubular column to raise and lower the column when the apparatus extends in a vertical direction and when it is desired to insert an end piston into or remove the end piston from the opposite end of the column or when it is desired to change an adapter ring on the first support member to receive a column of a different diameter for packing by the apparatus.

Title: Ubiquitin conjugating enzymes having transcriptional repressor activity
Inventor: WANG ZHAO-YI
IPC: C07K19/00
Filed: 1996-08-30
Abstract: A human ubiquitin conjugating enzyme, designated hUBC-9, its full amino acid sequence, and nucleic acid polymers which encode hUBC-9 are disclosed. In addition to having functional ubiquitin conjugating activity, this enzyme has transcriptional repressor activity which is independent of the conjugating activity. The conjugating activity of hUBC-9 enhances transcription through degradation of transcription suppressor proteins such as WT1, and possibly, of hUBC-9 itself. The repressor activity of hUBC-9 suppress gene transcription, probably by disrupting the transcriptional initiation complex through specific interactions with the DNA binding region of the TATA binding protein (TBP). In use, hUBC-9, yUBC-9 and other ubiquitin conjugating enzymes having repressor activity can be fused to proteins having a DNA binding domain, such as Ga14, or used in conjunction with repressors such as Wilm's tumor suppressor gene product, WT1. Such enzymes and the nucleic acid polymers encoding them can be used for regulating transcription of a target gene in both pharmaceutical and non-pharmaceutical applications.
Patent CA-2237213-A1 (CA)
Inventor: KERRIGAN KURT J
IPC: A01C23/04
Filed: 1998-05-08
Abstract: A method of applying chemical compositions to plant life such as, but not limited to, lawns, shrubs, plants, trees and gardens is disclosed and includes the use of an irrigation system having a main water delivery line for directing a pressurized flow of water from a water source to one or more water discharge devices. An air tight chamber is filled with a predetermined amount of a dry water-soluble or liquid chemical composition such as a fertilizer composition and/or a pesticide composition. A water input line connects from a first location along the main water delivery line to the chamber and a water output line connects from the chamber to a second location along the main water delivery line. The pressure of water flowing through the main water delivery line is higher at the first location than at thesecond location, causing a portion of the water flow to be diverted through the input line, into the chamber, through the output line, and feeding back into the main water delivery line at the second location. As water flows through the chamber, the dry water-soluble chemical composition therein gradually dissolves to produce a chemical solution. The chemical solution flows through the output line and into the main water delivery line so that the chemical solution mixes with water flowing through the main water delivery line. The mixture is then directed to the one or more discharge devices for application on to the plant life.

Patent CA-2257631-A1 (CA)
Title: Call transfer operation
Inventor: BERTACCHI LUCIANO
IPC: H04M3/54
Filed: 1997-05-16
Abstract: Responsive to an incoming call (34) made to a primary telephone number subscribing to a call transfer calling service feature, a first switching node (12(1)) queries (36) a data base (20) to retrieve (38) at least one transfer-to secondary number. The first switching node then signals (46) other switching nodes (12) in the telephone network (10) to set up an outgoing leg (48) to each secondary number telephone.   The signals transmitted by the first switching node further (50) direct each of the other switching nodes in the network to inhibit the initiation of any call transfer service features associated with the secondary number telephones. The signals may further include a transfer service indicator and a counter (80) identifying the number of prior call transfer which have occurred in connection with the originally received call. If the counter exceeds a given preset threshold (100), the other switching nodes reject further transfer of the call (102).

Filed: 1998-05-19
Abstract: A metallurgical furnace unit (1) includes a cylindrical furnace body (2) which is intended for rotation and/or tilting or like movement and is provided with at least one ring (7) mounted outside the furnace body (2) and functioning to enable such movement to take place. Each ring (7) is spaced from the furnace body (2) and connected to said body by means of a force transferring supporting-member (6) that extends in the longitudinal direction of the furnace unit (1). The supporting member (6) is adapted to prevent the transfer of furnace body movements caused by thermal expansion to the ring (7), and to take-up external loads from the intrinsic weight of the furnace body and the weight of the furnace charge. The invention is characterized in that the supporting member (6) has the form of a closed mantle which surrounds the furnace body (2) and which is connected to the furnace body (2) and to the ring (7) respectively by means of a flexible attachment that permits a given, limited change in the angle between the mantle (6) and the furnace body (2).  This angle may change as a result of movements of the furnace body (2) caused by thermal expansion. As a result of the inventive design of these attachments, these movements are eliminated, in the absence of any significant curvature or other deformation of the actual mantle (6).

Title: Composition, methods and reagents for the synthesis of a soluble form of human pex
Inventor: BOILEAU GUY
IPC: A61K48/00
Filed: 1999-02-24
Abstract: This invention relates to a soluble form of PEX, PEX being a type II integral membrane glycoprotein. This enzyme is the gene product of a phosphate regulating gene with homologies to endopeptidases on the X chromosome. To produce a soluble form of PEX, the transmembrane anchor domain has been modified to encode a signal peptidase coding sequence. The soluble PEX therefore comprises the active ectodomain. An inactive mutant of PEX is also an object of this invention.  Both soluble and inactive mutant forms of PEX can be used to screen ligands to PEX. These ligands will be used as substrates or inhibitors of PEX. PEX being phosphaturic, an inhibitor thereof will be used to treat phosphaturia and/or hypophosphatemia.  On the opposite, a substrate for PEX or PEX itself will be used to treat hyperphosphatemia.
