Patent CA-2106612-A1 (CA)
Inventor: PLIURA DIANA
IPC: A61K38/00
Filed: 1993-09-21
Abstract: Hemoglobin is purified from a crude solution thereof, to obtain an aqueous solution containing at least 99% of a preselected hemoglobin species, by a two stage displacement chromatography process. One of the stages is conducted under anionic exchange conditions, and the other under cationic exchange conditions. In both stages, the exchange column is overloaded to displace the hemoglobin species therefrom with contaminants having greater affinity for the column, and using the impure hemoglobin solution as the displaces. Normally, anionic exchange is conducted first, with contaminants more acidic than the hemoglobin displacing the hemoglobin from the column and themselves remaining attached to the column for separation. The cationic exchange process is conducted second, on the eluent from the first column, and in this stage, the more basic contaminants displace the hemoglobin from the column under overload conditions, to yield a substantially pure hemoglobin solution.

Title: Process for the Production of Permeation Resistant Containers
Inventor: HOBBS JOHN P
IPC: B29C49/46
Filed: 1993-11-29
Abstract: Plastic containers with excellent resistance to permeation by solvents are prepared by a multi-step treatment of the plastic containers in a controlled manner with fluorine containing gases while blow molding them.  In the process of the present invention, a parison is formed from a pre-heated thermoplastic material, expanded within a closed mold by means of an inflating gas for conforming the parison to the shape of the mold, and subjected to at least two fluorination treatment steps to effect fluorination of the interior surface of the parison.  In the initial fluorination step the parison is pressurized with a reactive gas containing no more than 1% fluorine by volume while the parison is at a temperature above its self supporting temperature and for a time sufficient to effect initial fluorination of the interior surface of the parison. Subsequently, the interior surface of the pre-fluorinated parison is pressurized with a reactive gas containing fluorine in a concentration that is greater than that used in the initial fluorination step.  Preferably, molecular oxygen contaminant in the parison is eliminated or minimized prior to and during fluorination.

Patent CA-2120689-A1 (CA)
Inventor: DOPPSTADT WERNER
IPC: B02C13/09
Filed: 1994-04-06
Abstract: The comminuting machine includes a housing provided with a rotary impact mechanism. A conveyor conveys infed material to the rotary impact mechanism which cooperates with an arcuate impact plate in disintegrating the infed material. The comminuted material is discharged through a discharge opening of the housing. On an inner side of the arcuate impact plate parallel rows of teeth extend transversely to the rotational direction of the rotary impact mechanism. The teeth rows are transversely and lengthwisely offset from each other. The individual teeth protrude in opposition to the rotational direction and decrease in height in the rotational direction.      The arcuate impact plate extends eccentrically in relation to the rotary impact mechanism and the tips of the teeth conjointly with the rotary impact mechanism define a throughpass gap for the material to be comminuted. A cover plate may be linked to the arcuate impact plate for closing the discharge opening and for downwardly deflecting comminuted material in the open condition.

Patent CA-2123165-A1 (CA)
Title: Seamless Basketball
Inventor: MEYER DARIN J
IPC: A63B41/08
Filed: 1994-05-09
Abstract: A basketball having a surface devoid of lines, seams stitching or other markings that span the circumference of the ball for  forming  a  uniform  and  continuous  surface.  The  seamless basketball has a uniform stippling along its entire surface and integrally a part thereof and may have a logo printed thereon. The ball  is  formed  from  a  molded  outer  cover  formed  from  two hemispheres having an inflatable bladder positioned therein. The inflation valve is hidden from view under the cover or, if exposed, is flush with the cover and of the same color as the cover. The lack  of  seams,  stitching  or  other  markings  spanning  the circumference of the outer surface of the ball causes the ball to have no particular orientation. Therefore, the user of the seamless basketball is not inclined to align the ball in a particular fashion prior to shooting the same.  As  such,  wasted time is eliminated and a quicker release and greater concentration is gained. Additionally, the ball is subject to a truer bounce because of the more uniform spherical nature of the same.

Title: Method and Apparatus for Configuring Computer Programs from Available Subprograms
Inventor: HURLEY DANIEL F
IPC: G06F9/06
Filed: 1994-07-20
Abstract: A graphic program configuration system is described that allows a user to create complete computer programs. In particular, the present invention improves on the prior art by providing a system and process that permits a subprogram to have an arbitrary number of outlets that may be defined at program configuration time by stimulating the subprogram to create new outlets that facilitate connecting the subprogram to other subprograms. In particular embodiments of the invention the names for the new outlets may either a) be obtained by virtue of the attempted connection of a subprogram to other subprograms or b) be provided direct entry of the outlet name by a user of the program configuration system, e.g., by typing the outlet names on the keyboard. Additionally, in accordance with an aspect of the invention, outlets can be augmented to have one or more constraining parameters that can be used to ensure that only appropriate relationships are established by connections. Such constraining parameters include: a) number of connections allowed, b) types of connections allowed, c) destination object class, and d) destination object operations required. Thus, a non-programmer or a person with only rudimentary programming skills can configure a collection of one or more subprograms into a complete computer program.

Inventor: PARTRIDGE B WARING III
IPC: H04W48/02
Filed: 1995-01-31
Abstract: The prior art deficiencies are solved, in accordance with the disclosure herein, by maintaining a list of caller identities and by determining, via reference to this list, the type of call treatment that an incoming call should receive. Thistechnique may be termed "divergent call treatment". The caller identities may betelephone numbers. The list of telephone numbers may be stored in the telephone company's switching facilities or in the subscriber's telephone instrument. A wide range of call treatment options are provided, and these options can be performedregardless of whether the list is maintained in the telephone company's switching facilities or in the subscriber's telephone instrument. In connection with cellular telephones, the divergent call treatment technique of the present invention is used to particular advantage. In accordance with one of the embodiments disclosed below, for example, the list maintained is a list of accepted callers, and it is maintained by the telephone service supplier. When a call comes in, a determination is made as to whether the caller is an "accepted" caller. If so, the call is forwarded to the cellular telephone. Otherwise, the caller is offered the option to pay for the call. A willingness on the part of the caller to pay for the call is indicated by a signal from the caller. This signal may be, for example, the pressing of one or more keys on a standard DTMF touch-tone pad, such as #1. In response to such a signal, the call is forwarded to the cellular telephone. In the absence of such a signal, the call is disconnected or diverted, for example, to the land line phone of the cellular telephone subscriber. When the list of accepted callers is maintained in the subscriber's telephone instrument, means are included to attenuate the ringing signal for an interval sufficient to provide appropriate call treatment for the call and, optionally, means are included for call forwarding, and/or recording of incoming messages.
