Title: Method for the production of in vitro expanded lymphoid cells for use in adoptive immunotherapy
Inventor: KNAZEK RICHARD A
IPC: A61K39/00
Filed: 1990-09-11
Abstract: This invention provides improved methods for in vitro culturing of therapeutic quantities of expanded subpopulations of lymphoid cells for use in methods of adoptive immunotherapy. Lymphoid cells, which are derived from a patient, are grown in a hollow cell fiber bioreactor culture system in the presence of at least one growth promoting substance, that specifically expands subpopulations of the lymphoid cells that are useful in methods of adoptive immunotherapy, including the treatment of cancer and genetic disorders. The improved methods of this invention provide convenient and inexpensive means for generating the large numbers of biologically active cells that are needed for adoptive immunotherapy.

Title: Pipeline repair sleeve assembly having heat sink groove
Inventor: SAVARD DONALD D
IPC: F16L55/17
Filed: 1992-04-29
Abstract: The assembly comprises a pair of semi-circular steel shells. The  inner surface of one  shell  forms a centrally located,  circular recess and a concentric groove positioned between the recess and the side edges of the shell.   A flat cylindrical annular seal element is seated in and fills the recess.   The element is resilient and deformable.   It has concentric protruding ribs on its top and bottom surfaces.  The seal element is adapted to circumscribe a leaking small hole or crack in the wall of an internally pressurized pipeline.  The shells are then circumferentially clamped against the pipeline to cause the element to seal around the leak and to effect tight shell-on-pipe  contact.   The  steel  side wall  of the recess confines the compressed seal element.   The side edges of the shell   are   then   welded   together   longitudinally   and circumferentially to create a permanent pressure vessel sealing and containing the leak.  The concentric groove acts as a heat sink to impede the transfer of heat from welding through the shell wall toward the seal element.

Abstract: ELECTRIC MOTOR          Abstract Field of Invention This invention comprises an electric motor of a comparatively flat profile, such profile being obtained by a new disposition of electro-magnetic components acting to produce mechanical power.    Essentially,  it  is  constructed from solenoids wound upon hollow circular tubes.  The dimensions of the tubes are chosen so as to allow one of such tubes to fit within the other, such tubes rotating independently but in close proximity to one another.  In cross-section  the  hoops  are  concentric  circles  of  slightly differing diameters.   In plan view   the hoops are themselves concentric circles.  The elements of the motor comprise two or more rings of solenoids or    permanent magnets spinning one within another.

Title: Apparatus and method for sorting objects
Inventor: REGIER ROBERT D
IPC: B07C5/18
Filed: 1992-04-16
Abstract: An apparatus for sorting objects (12) according to preselected weight and visually ascertainable criteria. Each object (12) is singulated and transported between adjacent pairs of a plurality of roller assemblies (100) attached to a conveyor chain (40) to be freely rotatable on a vertically slidable axis oriented normal to the conveying path. A control surface (162) along the conveying path causes rotation in the roller assemblies and in the object supported therebetween, increasing the surface of the object accessible for optical scanning (70). Mounted between each pair of roller assemblies (100) is a weighing cradle (103) subtending the object transported therebetween. The cradle (103) elevates and captures the object from its support between roller assemblies (100) so that the cradle (103) can engage a load cell (78). Pivotally mounted between each pair of rollers and subtending the object transported therebetween is an elongated discharge plate (104). Each object (12) is unloaded at an appropriate discharge location by pivoting upwardly the discharge plate (104).
