Title: Seeded porous copolymers and ion-exchange resins prepared therefrom
Inventor: HARRIS WILLIAM I
IPC: C08F265/04
Filed: 1992-11-25
Abstract: The invention concerns preparation of porous copolymer beads by a seeded polymerization process employing gel copolymer seed particles. The process comprises initially providing a plurality of gel-type copolymer seed particles prepared by polymerization of at least one first monovinylidene monomer and a first cross-linking monomer. A second monomer mixture comprising at least one second monovinylidene monomer, a second cross-linking monomer, and a phase-separating diluent is thereafter imbibed by the seed particles and polymerized therein. The process is characterized by selecting the first monovinylidene monomers such that the phase-separating diluent and second monovinylidene monomers are capable of being imbibed by the seed particles in an amount sufficient to form a porous copolymer. The porous copolymer beads produced have stable polymeric structures and good physical properties that render them useful in preparing ion-exchange resins and polymeric adsorbents.

Inventor: TANIBATA TORU
IPC: H04N1/00
Filed: 1994-05-26
Abstract: An image printer includes a projection exposure unit for projecting and exposing an image of a film onto a photosensitive material, an image exposure unit for exposing the photosensitive material based on exposure image information with setting an exposure amount  for  each  of  a  number  of  areas  of  the photosensitive material, a transport device for transporting the photosensitive material through the projection exposure unit and the image exposure unit, a reader device for reading the image information of the film with dividing the image information into a number of areas,  and a correction information inputting device for inputting a correction-target portion of the image information read by the reader device and a correction content for the correction-target portion.  Based on the image information read by the reader device and on correction information instructed by the correction information inputting means, the image exposure unit generates,  as the exposure  image  information,  image  information concerning  only the  correction-target portion corrected in accordance with the correction content.          The transport device transports the photosensitive material in such a manner that the projection exposure by the projection exposure unit and the exposure by the image exposure unit are effected in an overlapping -manner onto the photosensitive material.

Title: Immobilization of specific binding assay reagents
Inventor: LIN SPENCER H
IPC: G01N33/552
Filed: 1994-02-09
Abstract: Methods and compositions are provided for specific binding assays in which specific binding reagents are immobilized on a solid phase. Immobilization is facilitated by covalently coupling specific binding assay reagents such as polypeptide receptors or analytes with water soluble polymers. Such water soluble polymers, for example star polymers such as dendrimers, provide production advantages of lot-to-lot uniformity and homogeneity, and can enhance sensitivity due to low non-specific binding to the solid phase.

Patent CA-2138202-A1 (CA)
Title: Random orbit sander having braking member
Inventor: HOWARD THOMAS J JR
IPC: B24B23/03
Filed: 1994-12-15
Abstract: A random orbit sander having a braking member for frictionally controlling the speed of a platen of the sander when the sander is removed from a workpiece during operation.  The braking member includes a base portion,  an outwardly flaring,  relatively thin wall portion and an enlarged outermost edge portion adapted to frictionally engage an upper surface of the platen. The braking member is secured to the bottom of the shroud of the housing via a groove formed in its base portion.    The  braking member  exerts  a  relatively constant spring force against the upper surface of the platen which limits the rotational speed of the platen to approximately 1200 rpm when the platen is lifted off of a work surface, without significantly degrading the performance of the sander under load.  This prevents swirl marks and other undesirable scratches from being made in a workpiece when the platen is reapplied to the workpiece as a result of the platen having increased in speed to an unloaded,  free-wheeling speed,  and yet allows the platen to operate at or above the minimum desired working speed of about 800 rpm.  The braking member is formed from polyester butylene terephthalate which  is  doped with  approximately  2%  silicon  and approximately 15% teflon in the preferred embodiments. This material formulation, plus its geometry, allows the braking member to exert and maintain a relatively constant spring force of about 3.5 lbs. against the platen and to resist frictional wear once past an initial break-in period.  The braking member also acts as a seal between the lower surface of the shroud and the upper surface of the platen.

Patent CA-2141381-A1 (CA)
Title: Multi-compartment drum
Inventor: HANSON TERRY J
IPC: B65D21/02
Filed: 1995-01-30
Abstract: A longitudinally bisected storage drum includes a pair of hemi-cylindrical drum segments each being formed by a pair of semicircular end panels which are joined to, and spaced-apart by a side wall having a hemi-cylindrical wall section and a substantially rectangular planar wall section. The planar wall section of one drum segment defines a longitudinally oriented re-entrant groove which unites with a longitudinally oriented tongue protruding from the planar wall section of the other drum segment. Therefore, when the tongue and groove are united with one another, an overall cylindrical drum structure will result. The closely adjacent planar wall sections of each drum segment establish a diametrical parting plane when the tongue and groove are united with one another while the hemicylindrical wall segments are provided with longitudinally spaced-apart and outwardly protruding pairs of roll stops close to this parting plane. Thus, by simply reversing the vertical orientation of bungholes formed in each of the upper end panels (e.g., by rolling the drum along its cylindrical side wall until the it rests upon the other set of roll stops), the contents within the hemi-cylindrical drum segments can selectively be dispensed by positioning that segment's bunghole in the lower vertical position relative to the other bunghole.

A plurality of passages (38) are defined between the porous support structure (36) and the first distribution member (28) which distribute and remove the first reactant from the anodes (40). Each second module (26) comprises a second distribution member (54) which defines internal passages (56) for the supply of a second reactant to the fuel cells (22). The passages (30) in the first distribution member (28) contain a catalyst (74) for steam reforming the fuel. The catalyst (74) is in intimate thermal contact with the fuel cells (22).      Additionally a low temperature adiabatic prereformer (66) supplied with hydrocarbon fuel prereforms the fuel and supplies it to the passages (30). (Figure 1)

Filed: 1993-10-15
Abstract: A process is provided for reducing the inhibiting effect of gas coning on liquid hydrocarbon production into a production wellbore penetrating a subterranean formation having a gas cap overlying a liquid hydrocarbon producing zone in fluid communication with the gas cap. A polymer enhanced foam containing a polymer, an aqueous solvent, a surfactant, and a gas is placed in gas-permeable anomalies or matrix between the production wellbore and gas cap, thereby effectively blocking the downward flow of gas from the gas cap to the production wellbore and enabling desirable liquid hydrocarbons to more readily enter the wellbore for production to the surface.

Title: Satellite monitoring bar
Inventor: MCGRATH JOHN E
IPC: H01R13/00
Filed: 1995-04-24
Abstract: A consolidated monitoring cable arrangement allows multiple cables extending between a surgical gurney, or other type of patient support platform, and a peripheral monitoring stand to be consolidated into a single cable. The present use of multiple cables has the disadvantage that the region between a gurney and a monitoring stand is cluttered. This can present a hazard to medical personnel, particularly when an emergency situation requires that concentration be focused on the needs of the patient. In a primary form, the subject cable arrangement uses two boxes, one on the gurney and another on the monitoring stand; a detachable cable connects the two boxes. Shorter cables of uniform length are used to connect a patient on the gurney and equipment on the monitoring stand to a respective box. Besides the aforementioned safety advantage, this cable arrangement reduces the expense of frequent replacement of damaged cables.
