Title: Reflux fluid heated patient line
Inventor: VERKAART WESLEY H
IPC: A61M5/44
Filed: 1991-06-19
Granted: 2002-12-10
Abstract: A heat exchanger useful for supplying infusates over substantial distances uses an extrusion which provides a central tube for carrying an infusate and two outer channels for carrying a heat exchange fluid. A first of the channels carries the heat exchange fluid from an inlet end to an opposite end and the other of the channels returns the heat exchange fluid to the inlet end. An end cap at the inlet end is easily connected to a source of heat exchange fluid and communicates with the channels. An end cap at the opposite end receives the heat exchange fluid from the first channel and redirects it to the second channel. Both of the end caps have connectors for facilitating connection with lines from a source of infusate and a patient.

Patent CA-2060495-C (CA)
Inventor: MCNAUGHTON JAMES
IPC: F16L37/098
Filed: 1992-01-31
Granted: 1999-07-27
Abstract: A unique quick connect fluid coupling is disclosed in which tube  inner end does not contact a seal  if  the  tube is not  fully connected.   Preferably, a retainer retains  the  tube within the bore. The retainer is of the avalanche type such that a high force is required to insert the tube, and once this high force is overcome the momentum of the tube carries it to its fully inserted position.  No seal is formed between the tube and seals within the housing unless the tube has moved beyond the point where the high force begins.  Once the tube has moved beyond that point,  it will be fully connected.  The invention ensures that there would be no seal between a tube and a housing unless the tube is fully connected.

Title: Identity verification system resistant to compromise by observation of its use
Inventor: MARTINO MICHAEL J
IPC: G06F21/14
Filed: 1993-02-11
Granted: 1997-03-18
Abstract: A mechanism for an automated system to allow a user of the system to demonstrate his legitimacy by demonstration of secret knowledge.  The mechanism is resistant to compromise by observation of its use.  An array of symbols is presented to the user and the user is required to manipulate several symbols at once until assigned key symbols are manipulated into predetermined states.  Doing so effectively prevents an observer  from determining which  symbols are  the  ones of interest.  For example, pushing a button might cause several symbols in the array to exchange their positions.  The user continues  to  do  this,  having,  perhaps,  to  use  several different buttons,  until a certain subset of the symbols appears in certain locations within the array.   (In this example, the arrangement of this subset of symbols is the user's password or PIN.)   In this process many symbols in the array, in addition to the user's specific symbols, would also have been moved, making it virtually impossible for an observer to identify which symbols and array-positions are pertinent to the user's password or PIN.

Title: Apparatus and method for non-regular channel assignment in wireless communication networks
Inventor: BENVENISTE MATHILDE
IPC: H04W16/02
Filed: 1993-04-14
Granted: 1999-02-16
Abstract: A channel assignment system assigns channels to various cells by the optimal partitioning of the available radio frequencies into non-overlapping sets, the optimal grouping of co-user cells, and the best assignment of the former to the latter. The objective is the maximization of traffic handling capacity which, given the multitude of cells, is expressed as the maximization of a bottleneck capacity ratio. The capacity ratio for a cell is defined as the ratio of the number of radio frequencies assigned to the cell over the number of radio frequencies needed to meet blocking probability requirements. The solution to attain an optimal non-regular channel assignment is decomposed into two mathematical programs designated a Master Program and a Subprogram. These are solved iteratively with assistance from a channel set augmentation technique impelmented between solutions of the Master and Subprogram.

Filed: 1993-07-23
Granted: 1999-12-14
Abstract: Bitumen is recovered from oil sands in an ambient temperature procedure in which the oil sands first are subjected to attrition in the presence of an aqueous sodium hydroxide solution to form a slurry of pH at least about 11.5. Sand, freed from bitumen, usually is separated from the slurry, which then is diluted with further quantities of aqueous sodium hydroxide solution while maintaining the pH value, so as to provide the bitumen in a form which can be separated from the aqueous phase by flotation. The bitumen is floated off from the aqueous phase comprising a clay suspension and then forwarded to an upgrading operation. A second bitumen flotation also may be effected following addition of calcium hydroxide to the remaining aqueous phase. The clay suspension may be flocculated and dewatered and the resulting sodium hydroxide solution recycled to the attrition and/or dilution steps.
