Patent CA-2042799-C (CA)
Title: Chordal ring network
Inventor: KAROL MARK J
IPC: H04L12/42
Filed: 1991-05-16
Granted: 1998-08-11
Abstract: A plurality of NIUs (Network Interface Units) are interconnected by a multiple channel communications medium, and each NIU includes a sequence of inputs and outputs. Each channel is connected to a separate input, and exits theNIU at a separate output. The output that each channel exits is connected to thenext input in the sequence of inputs on the next connector in the chordal ring. Further, channels which enter at a predetermined input of the NIU are cut and connected to a user equipment before exiting the NIU. Thus, if a predetermined channel is cut and connected to a particular user equipment, it will not be cut again at the next NIU since it will enter the next NIU at a different input in the input sequence. Indeed, the channel will not be cut again until N NIU's are traversed,where N is the length of the sequence. Thus, by choosing N to be the chordal length, an NIU is constructed which may be connected in an identical fashion to each user equipment in order to automatically establish chords in the network.

Title: Soil remediation process and system
Inventor: MONLUX KENNETH J
IPC: B09C1/06
Filed: 1991-03-06
Granted: 1995-02-07
Abstract: Process and apparatus for near-zero discharge soil remediation, preferably in conjunction with an asphalt plant, compris-ing heating soil contaminated with up to about 30,000 ppm light hydrocarbons in an inclined, axially-fired rotating separator, and sampling the output soil to determine the remaining contaminants. If below 100 ppm (preferably 10 ppm) it may be reem-placed as clean fill. If it does meet D.O.T./CALTRANS standards and is below about 100 ppm it may be used as roadbed fill. If between about 1000 and 100 ppm and meets standards it may be used as aggregate, being mixed with hot oil to form asphalt. The separator offgases are condensed, the reclaimed liquid hydrocarbons separated and combined with the hot oil. The hot condenser offgases are supplied as secondary air to a main dryer, improving efficiency of operation. A dust/mud blow down system clears the heat exchange plenums with compressed air.

Title: Storage of materials
Inventor: FRANKS FELIX
IPC: A61K35/12
Filed: 1992-06-25
Granted: 2002-09-17
Abstract: Materials which are not themselves storage-stable at room temperature are made suitable for storage by mixing them with a carrier substance and spray drying the resulting mixture so as to form particles containing both the material and the carrier substance in which the carrier substance is in an amorphous, i.e. glassy or rubbery, state. Formation of such a composition greatly enhances stability.

Granted: 2002-07-23
Abstract: The present invention concerns a screening method and apparatus for sorting wood chips into three categories, namely, accept chips, overthick and/or overlong chips requiring further processing and reject fines. The chips are fed onto a disc screen. A major portion of fines and a portion of accepts fall by gravity through clearances between the discs (1) of the disc screen and a portion of the chips travels over the disc screen. Screening of chips on the disc screen is cut short before all accept chips have fallen through the disc screen. Chips travelling over the discharge end of the disc screen are routed onto a roller screen (10), whereby the remaining portion of accepts can fall by gravity through the roller screen while overthick and/or overlong chunky chips are conveyed over the discharge end of the roller screen.

Granted: 1997-07-01
Abstract: A motion detection radar system that is adapted to produce radar warning signals regarding the presence of moving objects that are located behind structural barriers and the like is comprised of a low power frequency tunable continuous wave transmitter and antenna, a receiver, an FM transmitter and antenna, and a handheld remote FM receiver.  The radar system may be adapted to operate at any frequency from 600 MHz to 1.2 GHz.  The motion detecting radar system uses a technique for measuring the changes in phase difference and the rate of change of phase differences detected thereby. The receiver captures the total energy reflected from all reflective objects within the antenna field of view and compares that signal with the transmitted signal in a mixer.  If all objects are stationary and the radar system is stationary, the total complex phase pattern of the return signal is constant, and a fixed DC output signal is provided from the mixer.  Any motion within the field of view changes the fixed phase relationship and causes a phase rate of change at the receiver output. The phase rate of change is converted into a tone which allows an operator to recognize object motion.  The tone is transmitted by the FM transmitter to the remote FM receiver used by the operator to monitor monitor object motion.  The receiver output is almost inaudible when there are no moving objects, but an alarm tone is provided when object motion is present.  The detection process used in the motion detecting radar is unique in that it captures minute changes in the complex signal from all reflectors and converts the moving object differences into the audible alarm.
