Title: Method and device for forming flanges on plastic pipe
Inventor: MCMILLAN JAMES S
IPC: F16L23/026
Filed: 1991-04-24
Abstract: A method aid apparatus are shown for forming a flange on pan end of a plastic pipe liner of the type used to line a tubular member. A reinforced disc hawing a rigid portion and an elastomeric portion is placed about the liner exterior and moved into position flush with the flanged end of the tubular member. A retaining ring is placed about the reinforced disc and the disc and liner exposed end are heated to render the materials malleable. A forming unit is then used to apply force to the liner to flow tine liner into a reformed shape having a greater external diameter than the remainder of the liner. The forming operation also bonds the reinforced disc to the reformed liner end to further resist any tendency of the liner end to be retracted into the interior of the tubular member.

Title: Project organizer for business with label control
Inventor: ANNAND CHARLES A
IPC: B42F13/00
Filed: 1992-10-30
Abstract: PROJECT ORGANIZER FOR BUSINESS WITH LABEL CONTROL            ABSTRACT            This organizer allows a conventional multi-ring binder to be used with the standard half pages and a new clipped page to give double the amount of spaces in any one section for the control of projects.   The clipped page results in a quarter inch page spacing which allows a single line system to be printed on a self-adhesive computer label, which then can be attached to the top of the page to give a single line control over  the  key  words  which  define  the  project  on  that particular page.   The quarter inch spacing, now possible by means of the clipped page, allows a single line to be visible to the user rather than multiple lines which cause confusion in defining the project by key words, only with the clipped page system is this quarter inch exposed top line on these pages possible.   The quarter inch top line spacing allows a computer label  to be generated with   bold capital letters for the key words in the top line to define the project and be visible to the user and prevents confusion in defining the project and is only possible because of the clipped page system.  The single exposed top line also resembles the menu systems  now  used  with  computers and  is  therefore  more acceptable to the user.

Patent CA-2087411-A1 (CA)
Inventor: LAKOWICZ JOSEPH R
IPC: A61B5/1459
Filed: 1993-01-15
Abstract: ABSTRACT OF THE INVENTION      A method for measuring the concentration of a saccharide, conjugated  saccharide  or  polysaccharide  of  interest  using luminescent  lifetimes  and energy transfer in which an energy transfer donor-acceptor pair is added to a sample to be analyzed, the donor of the donor-acceptor pair being photoluminescent.  The acceptor is bound to a carrier, while the donor and any saccharide, conjugated saccharide or polysaccharide of interest present in the sample compete for binding sites on the carrier. The sample is irradiated and the resultant emission detected.  Energy transfer occurs between the donors and the acceptors,  which produces a detectable lifetime change of the fluorescence of the donor.  The lifetime change is reduced or even eliminated by the competitive binding of a saccharide, conjugated saccharide or polysaccharide of interest to the donor.  By measuring the apparent luminescent lifetime,  the amount of a saccharide, conjugated saccharide or polysaccharide of interest in the sample can be determined.

Title: Bidirectional video telephony between cable television and switched telephone systems
Inventor: BINNS WALTER P
IPC: H04M3/42
Filed: 1993-03-29
Abstract: In a video telephony system, a coaxial cable network (121, 126), which is preferably a part of an existing cable television system (121, 126, 122, 127), provides a local link for the transmission of the video telephone signals between each originating and destination location (101, 105) and a respective "head end"(122, 127) located on the cable company premises. Each of the head ends is connected to a "point of presence" (161, 162) of a telephone interexchange carrier so that a connection between pairs of head ends, and thus between a pair of video telephone locations, can be made via a switched digital network (160) maintained by the carrier. Certain of originating and destination locations comprise a standard television set (103, 106), serving as the audio/video display, and a consumer-type camera or camcorder, serving as the audio/video source. Others of the originating and destination locations comprise ISDN video telephones (111, 115) which are connected to the various points of presence of the interexchange carrier via local exchange carrier telephone networks (140, 145). The video telephone numbers for cable subscriber locations are administered to be the same as the standard ten- (i.e., area code plus seven-) digit telephone number used for regular telephone calls directed to those locations.

Title: Biodesulfurization of bitumen fuels
Inventor: VALENTINE JAMES M
IPC: C12S1/02
Filed: 1991-11-20
Abstract: A simple and effective biochemical process solves the problems associated with sulfur in bitumen by removing sulfur from active participation in SO x-producing combustion reactions. In one aspect, an emulsion of bitumen and water is contacted with a microbiological desulfurization agent for a time and under conditions effective to reduce the oxidizable sulfur con-tent of the bitumen. The preferred agents do not affect the heating value of the fuel, but selectively oxidize organic sulfur to water-soluble sulfates which can either be physically removed or chemically bound so that they do not cause SO x produc-tion. Multistage reaction is employed to enhance sulfur removal.

Patent CA-2112711-A1 (CA)
Inventor: SARUWATARI MINORU
IPC: F04B47/04
Filed: 1993-12-31
Abstract: A hydraulic drive system for actuating a reciprocating member such as a polished rod in a pump jack device, and for acting as a counterbalance and/or for energy conservation. The system has two hydraulic circuits and a prime mover. A first circuit includes a cylinder for driving an output member which may be connected to the polished rod, a first pump of the variable displacement, reversible flow type, together with a pair of fluid lines forming with the cylinder a closed-loop circuit.          A controller is programmed to control the setting of the first pump so as to establish the velocity profile of the output member. A second hydraulic circuit is also in the form of a closed-loop containing first and second pumps, at least one of which is of the variable displacement type and is also controlled by the controller. The second and third pumps at least are of the pump/motor types, and the third pump has an input/output shaft connected to a flywheel so that as the third pump is driven as motor, it increases the speed of the flywheel. However, when the second circuit is controlled so that the second pump functions as a motor and the third pump functions as a pump, energy is extracted from the flywheel so that its RPM decreases.           The first pump is driven by the prime mover, and the second pump, which can drive the first pump when it is functioning as a motor, may alternatively be driven by the prime mover as well or by both the prime mover and the first pump, if the latter functions as a motor, such as during the down stroke of the polished rod.

Title: Coffee maker
Inventor: FONTYN JAN H
IPC: A47J31/44
Filed: 1994-04-21
Abstract: Disclosed is a coffee maker having an upper compartment in which can be slid a basket provided with a spring biased drip-stop valve, and a lower compartment in which a coffee pot can be inserted.  The upper compartment has a top panel that can be moved down by a manually operated lever, and a spring-loaded double floor that is also movable downwardly and provided with an extension that is sized and positioned to fit into the neck of the coffee pot located in a lower compartment so as to close this coffee pot and, more importantly, to lock it in the lower compartment. This coffee maker is particularly well adapted for use in aircrafts, since it avoids any dripping within the cabin when the drawer is removed, and, more importantly, it allows the basket and coffee pot to be "locked" within their respective compartments when the lever is pushed down, to prevent them from falling out during take-off and landing.
Patent CA-2122019-A1 (CA)
Title: Transient-free synchronous electrical power machine
Inventor: FARKAS OTTO
IPC: H02K7/02
Filed: 1993-02-16
Abstract: Proximity switches and circumferentially movable stator windings allow a motor-generator (2) to simultaneously sense and switch from a synchronous motor position to a synchronous generator position. The mechanism replaces the conventional separate sensing and switching of motor-generator functions. Automatic rotational repositioning of the stator (21) maintains constant voltage and prevents the generation of transient voltages or harmonics. The stator flux leads the rotor magnetic flux slightly in a motor position.  As the stator field weakens due to a failure of the normal power supply, the counter torque also weakens and the stator windings are biased to begin to turn with the rotor (27) until the rotor and stator fields are in step, i.e., when virtually no current is generated or consumed or until a generator position is reached.  The dynamic stator may also be used in electric motors or generators to filter or cushion variations in the power supply or in the load.
