Patent CA-2146386-A1 (CA)
Inventor: WATSON CHRISTOPHER L
IPC: F02M1/10
Filed: 1995-04-05
Abstract: An air inlet control system for a carburetor of an internal combustion engine. The system includes a magnet, an air inlet valve, and a temperature controlled limiter. The magnet is used to automatically attract the air inlet valve towards a fully closed position. The temperature controlled limiter limits the range of movement of the air inlet valve based upon the temperature of the engine. The limiter limits the open position of the valve to a position less than fully open when the engine is cold and, limits the closed position of the valve to a position less than fully closed when the engine is hot.

Title: Electric iron with reservoir fill-check
Inventor: MORRISSEY MICHAEL D
IPC: D06F75/14
Filed: 1995-05-08
Abstract: An electric iron includes a soleplate and a housing connected to the soleplate.  The housing forms a water reservoir.  An opening is formed in an outer wall of the housing. A valve seat is formed adjacent the top of the opening. A float valve having a specific gravity less than one is movably disposed within the reservoir.  The valve moves into engagement with the valve seat to prevent the flow of water through the opening when the water level in the reservoir raises the valve into engagement with the valve seat.

Title: Use of p2o5 in non-aqueous rechargeable lithium batteries
Inventor: ZHONG QIMING
IPC: H01M4/131
Filed: 1995-06-02
Abstract: The loss in delivered capacity as a function of the number of charge/discharge cycles in non-aqueous rechargeable lithium batteries can be reduced by exposing the electrolyte therein to P2O5. The exposure to P2O5 can be accomplished by incorporating P2O5 in either electrode or other locations that contact the electrolyte. Alternately, the electrolyte can be exposed prior to assembling the battery. The invention is particularly suited to certain lithium ion rechargeable battery electrochemistries.

Patent CA-2155630-A1 (CA)
Title: Low temperature albumin fractionation using sodium caprylate as a partitioning agent
Inventor: TENOLD ROBERT A
IPC: A61K38/00
Filed: 1995-08-08
Abstract: Highly stable plasma-derived therapeutic albumin solutions, having a turbidity level of 5 NTU or less can be made by adding sodium caprylate to Cohn fraction II+III or IV-1 effluent at relatively low temperatures. The sodium caprylate acts as a partitioning agent to separate albumin from unwanted proteins. In preferred embodiments, the albumin source solution temperature is elevated, increased in pH and reacted for approximately six hours under conditions sufficient to disrupt the initial solution colloid, and partition albumin-containing supernatant from a colloidal disperse phase, which retains unwanted globulins and manufacturing debris.  Since it tends to be a scavenger molecule, albumin is selectively stabilized by diafiltration against a buffer containing sodium caprylate, thereby assuring a high albumin monomer content and low turbidity level. The amount of sodium caprylate required for selective stabilization is determined by the amount of available binding sites on the albumin molecule.

Materials produced via this method include layered materials which can be utilized as precursors in the formation of other manganese oxide products and molecular sieves which, due to their high thermal stabilities, can be utilized in high-temperature catalytic applications.
Patent CA-2160934-A1 (CA)
Inventor: GRANT ROBERT H
IPC: H04B10/075
Filed: 1995-10-19
Abstract: A frame time monitoring system (100) tracks the time in which data frames  (11)  reside within a fiber optic switch (30) for a fiber optic network.  The network switch (30) transfers data frames (11) from source ports (33) to destination ports (33).  The frame time monitoring system comprises a digital signal processor (DSP) (100a), which is configured by a software program  (108)  to implement a plurality of timers  (164) relative to frames  (11)  to be routed through the switch (30) from a source port (33) to a destination port (33).  The processor (100a) operates as an incrementer and is configured to output a series of sequential  timer  states  (144)  corresponding  to  each particular  frame (11).    The  timer  states  (144)  are generally indicative of the amount of time in which the frame (11) has resided in the switch (30).  A logic network (100b) of logic gates is connected to the processor (100a) to receive and interpret the timer states (144).  The logic network (100b) has frame busy (FBSY) and delete mechanisms (204, 207) for determining elapse of respective FBSY and delete time periods based upon the timer states (144).  The FBSY and delete mechanisms (204, 207) generate respective FBSY and delete signals (146, 147) after the elapse of the periods, which can vary for optimization reasons depending upon  frame class  and  type.    Thus,  in  the  foregoing configuration, a processor (100a) is utilized as a timing incrementer and logical decisions are allocated to the logic network  (100b),  resulting  in an optimum balance between hardware and software so as to minimize cost, space requirements, and complexity, and maximize frame tracking resolution.

Patent CA-2163662-A1 (CA)
Title: Dna sequencing by stepwise ligation and cleavage
Inventor: BRENNER SYDNEY
IPC: C12Q1/68
Filed: 1995-03-24
Abstract: The invention provides a method of nucleic acid sequence analysis based on repeated cycles of ligation to and cleavage of probes at the terminus of a target polynucleotide.  At each such cycle one or more terminal nucleotides are identified and one or more nucleotides are removed from the end of the target polynucleotide, such that further cycles of ligation and cleavage can take place. At each cycle the target sequence is shortened by one or more nucleotides until the nucleotide sequence of the target polynucleotide is determined. The method obviates electrophoretic separation of similarly sized DNA fragments and eliminates the difficulties associated with the detection and analysis of spatially overlapping bands of DNA fragments in a gel, or like medium. The invention further obviates the need to generate DNA fragments from long single stranded templates with a DNA polymerase.

Title: Convenient "drop-down" respirator
Inventor: BYRAM DAVID C
IPC: A62B18/08
Filed: 1994-08-05
Abstract: A respirator (15) has a harness (10) that allows the respirator body (20) to be conveniently disposed beneath a wearer's chin when not in use. The harness (10) includes a substantially flat, flexible strap (14) and an element (12) that contains a curved elongated slot (16). The subtantially flat, flexible strap (14) is threaded through the curved elongated slot (16). The curved configuration of the slot (16) causes the flat flexible strap (14) to be deformed to assume the curved configuration of the slot. This deformation of the strap (14) allows the strap (14) to frictionally engage element (12), and the frictional engagement allows the respirator body (20) to be incrementally withdrawn from the wearer's face so that it can be temporarily stored beneath the wearer's chin, and allows the respirator body (20) to be conveniently repositioned over the nose and mouth of the wearer by simply pulling on free ends (34) of each strap (14) and joining a buckle (32) behind the wearer's neck.

Title: Simulcast of interactive signals with a conventional video signal
Inventor: HARPER GREGORY W
IPC: H04N7/173
Filed: 1995-04-14
Abstract: A system for simulcasting a fully interactive program with a normal conventional program in the same standard video signal bandwidth. It allows active participation by subscribers who have interactive components (600) connected to a television (186) or personal computer display (187), as well as normal viewing of the conventional program by viewers with conventional television sets (186). An important feature is that interactivity is offered as an option, without any degradation or interruption in program content to users who do not have the interactive components (600). Interactivity is personalized through the use of alternative audio responses and/or graphic displays that can be provided as part of the transmitted video signal bandwidth. The interactive elements are presented to the subscriber either immediately after subscriber entry and/or later at transparent "trigger points" (900). At trigger points (900), program content is subtly altered to present specialized attention to each interactive subscriber.
