Title: Methods for modulating t cell unresponsiveness
Inventor: BOUSSIOTIS VASSILIKI A
IPC: A61P31/00
Filed: 1995-03-08
Abstract: Methods for modulating antigen-specific T cell unresponsiveness which involve inhibiting or stimulating an unresponsive T cell through a cell surface receptor, CD2, are disclosed. Agents which inhibit stimulation of an unresponsive T cell through a CD2 surface receptor are useful therapeutically in situations where it is desirable to inhibit an immune response to an antigen(s), for example in organ or bone marrow transplantation and autoimmune diseases. Methods for reversing T cell unresponsiveness by contacting the T cell with an agent which stimulates the T cell through a CD2 surface receptor are useful therapeutically to stimulate an immune response to an antigen(s). For example, the method is useful to stimulate an anti-tumor response in a subject with a tumor or stimulate a response against a pathogenic agent or increase the efficacy of vaccination.

Inventor: HAWKINS LARRY LEE
IPC: D06F37/24
Filed: 1997-01-30
Abstract: An easy to assemble upper ball joint assembly for a wash tub suspension system is described. In accordance with one embodiment, the upper ball joint assembly includes a socket configured to be located within a keyed opening in the suspension system upper frame, and a ball joint configured to be secured to a suspension rod extending from the suspension system lower frame through the opening in the upper frame. The socket includes a seating surface which, in one embodiment, is substantially spherical shaped and concave. A slot extends from the socket opening to a periphery of the socket. The slot is configured so that the suspension rod can be moved through the slot and located within the socket opening. By orienting the socket so that the slot extends radially outward from a center axis of the wash tub, the suspension rod is allowed more movement relative to the socket since the rod can also move within the slot. The ball joint has a seating surface for mating with the socket seating surface, and the ball joint seating surface is substantially spherical shaped and convex. The ball joint further includes a substantially cylindrical central support member. A support flange extends from a periphery of the ball joint seating surface, and a plurality of support members extend from the support flange to the substantially cylindrical central support member. The suspension rod extends through an opening in the ball joint, which opening includes a bore extending through the central support member, and an end of suspension rod is deformed, or crimped, so that the ball joint is trapped between the end of suspension rod and the socket.

Title: Animal alignment guide for a nipple valve waterer
Inventor: GERBO MICHAEL R
IPC: A01K7/00
Filed: 1997-06-13
Abstract: The present invention provides an animal waterer having an animal alignment guide attached to the water supply line near the juncture of the terminal conduit and the nipple valve. The guide includes an interior portion attached to the water supply line and a pair of guide wings extending out on opposite lateral sides of the nipple valve about the same distance as the trigger of the nipple valve. The vertical position of the nipple valve is adjustable so that the nipple valve can be easily and quickly positioned at the most efficient drinking height for the size of animal being watered. One embodiment of the waterer includes a waterer fed by a flexible feed line, and supported by a chain to freely swing at an elevation of about two inches above the backs of the animals. A  second swinging embodiment includes a suspension bracket which extends up from the vertical axis of the supply line for connection with a chain so that the waterer will hang straight. Also, this second embodiment uses a single triangular bend in the terminal conduit so that the terminal conduit is inclined downwardly and has no horizontal sections. This configuration eliminates the buildup of excess galvanizing material in the interior of the terminal conduit when the unit is submersed in and withdrawn from the vat of zinc galvanizing material during the plating process.

IPC: H04M3/50
Filed: 1997-07-17
Abstract: A method and system adaptively substitutes a single dialing button sequence for a selected action in a voice menu of a telephone system. A shortcut message in the voice menu prompts a caller to select a shortcut button to acheive a shortcut action. The system then accumulates counts related to frequencies of occurrence of a plurality of actions prompted by the voice menu. The system then ranks the plurality of actions by their respective accumulated counts and determines if any one of the plurality of actions has an accumulated count greater than an accumulated count of the shortcut action. If it does, then the system causes the substitution the one of the plurality of actions and a corresponding message for the shortcut action and the shortcut message in the voice menu.

Abstract: The build up of unwanted components, particularly potassium and chloride values, in pulp mill recovery cycles is avoided by processing pulp mill recovery cycle precipitator ash. The ash first is dissolved in water and the aqueous solution then is evaporated to crystallize sodium sulfate, which then can be returned to the pulp mill recovery cycle. The mother liquor from such crystallization is subjected to extractive crystallization to recover further quantities of crystalline sodium sulfate for return to the pulp mill recovery cycle. The purge stream containing chloride values is removed from the cycle.

Filed: 1996-09-18
Abstract: In a communications network, call records are generated by a plurality of originators (CLI#1, CLI#2, CLI#3) making calls to a service provider (180).  The call records are stored in a database (145) which forms part of the billing function (140) of the network. The call records for the service provider (180) are collated and sent to the service provider for processing.  The service provider is provided with a system for analysing the call records to establish the number of lost callers, rather than the number of lost calls.  This is possible since the call records include the CLI information of the originators. This information, gathered over a predetermined period of time, allows the service provider (180) to estimate the number of answering stations (170) necessary to optimise call answering and minimise the number of lost callers.
