Patent CA-1278916-C (CA)
Title: Sludge processing
Inventor: ERDMAN ANDREW JR
IPC: F26B3/24
Filed: 1987-05-19
Granted: 1991-01-15
Abstract: ABSTRACT        Methods for continuous drying of sludges.  Large scouring particles are added to a sludge to be dried to create a mixture which is passed through a rotary screw type indirect heat exchanger. The scouring particles are large relative to the particulates of suspended and dissolved solids which result from drying in the heat exchanger.          During the process of drying and conveying the mixture through the heat exchanger the scouring particles continuously remove the particulate residue from the surfaces of the heat exchanger.  It also appears that the particles assist in the actual heat transfer between the heat exchanger surfaces and the sludge by absorbing and subsequently releasing heat through relatively large surface areas.  The scouring particles can be consumptive, that is, consumed in processes during subsequent handling of the residue, or nonconsumptive.  In the nonconsumptive case, upon discharge from the heat exchanger the scouring particles are separated from the particulate residue and recycled for mixing again with the sludge.

Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE        Optical pyrometers such as for a gas-turbine engine have a fibre-optic cable that supplies radiation from the engine blades to a remotely mounted detector.  The output from the detector is amplified and processed to provide an indication of temperature.    In the present invention the detector includes a photodiode and an amplifier that are mounted in a cylindrical metal casing that forms one end of the fibre-optic   cable.  The detector casing has a connector that is mateable with a connector on the casing of a separate processing unit so that the detector can be electrically connected with the processing unit without the need for cables between the two casings.          The detector connector has a flange that provides good thermal contact with the connector on the processing unit so as to help equalise the temperatures of the two casings.  The processing unit casing is cooled by means of a thermal transfer unit supplied with liquid fuel.  The processing unit has an electrical circuit that processes the output of the detector circuit and inputs from other sources to provide an output to an engine control unit.

Title: Hydraulic steering system
Inventor: MCBURNETT JAMES R
IPC: B62D5/06
Filed: 1988-07-25
Granted: 1994-05-03
Abstract: ABSTRACT OF THE DISCLOSURE      An hydraulic steering system for a ground-engaging, self-powered vehicle, the system including an engine driven primary pump for pumping hydraulic fluid to the steering system when the vehicle engine is operating and a wheel-driven secondary pump for pumping hydraulic fluid to the steering system when the vehicle is in motion, even if the engine or the engine driven primary pump is inoperable, or if the output of the engine driven primary pump is inadequate.  The wheel-driven secondary pump is an over-center, axial piston pump which is controlled so that it is uni-directional in its output regardless of any change in direction of its input power source and which, thus, avoids the need for check valves in the hydraulic lines of the secondary pumping system, regardless of whether the vehicle is moving forward or in reverse when the engine becomes inoperable.

Title: Ground start circuit
Inventor: PERRY STEVEN B
IPC: H04M1/24
Filed: 1988-08-12
Granted: 1991-11-26
Abstract: Abstract of the Disclosure Various embodiments of a ground start circuit suited for use in telecommunication applications, illustratively in conjunction with a ground start line, and a method for use in the circuit for invoking ground start operation on such a line are described.  In essence, as soon as a telephone line is connected across the inventive ground start circuit, a potential difference that appears between a ring side of a two-wire telephone line and earth ground causes a control voltage internal to the circuit to increase in magnitude.  Once this control voltage reaches a threshold value, then the circuit establishes a low impedance path between the ring side of the line and earth ground in order to place the line in an unbalanced condition.  This low impedance path is maintained until a central office connected to the line at a remote end thereof senses the unbalanced condition and, in response, applies battery voltage to the line to cause loop current to flow therethrough, i.e. through a loop formed of tip and ring wires that form the line.  As soon as the inventive circuit detects the presence of loop current through, for example, a resistive loop current detector, the circuit eliminates the low impedance path thereby returning the telephone line to a balanced condition.  At this point, the inventive circuit becomes substantially electrically transparent to normal functioning of the line.  The central office then applies dial tone to the line in order to allow a caller to initiate an outgoing call.

In that integrated portion, a switch is disposed in each one of two lines, which connect the integrated portion and each substation.  Further, a switch is provided in a line which bypasses these two switches. Other systems are a composite of the above systems.  Still other systems have automated portions of fault location and fault recovery.

Title: Bus data path control scheme
Inventor: KIRK JOHN
IPC: G06F13/40
Filed: 1988-10-19
Granted: 1993-06-15
Abstract: ABSTRACT OF THE DISCLOSURE      A bus data path control scheme facilitates communications in a data processing system between subsystem elements that have different data widths.  A plurality of buses is provided whereby each subsystem or element is connected to one of the plurality of buses. A control logic array detects requests to transfer data between subsystems.  Each of the plurality of buses are connected to one another through a bidirectional transceiver.  Once the control logic array detects the request for transferring data between subsystems, the array and the transceiver operate in concert to permit subsystem devices having different data widths to communicate with one another.  In particular, the array and transceiver act to redirect data so that as it is shifted from a first bus to which the sending subsystem is connected to a second bus to which the receiving subsystem is connected, the data is moved into the proper bit location on the second bus so as to be received properly by the receiving subsystem.

Abstract: A corrosion control composition and method for boiler/condensate steam systems is provided.  Corrosion is controlled by the addition to the feedwater of a relatively high molecular weight amine.  The high molecular weight amine is formulated so that at the conditions of temperature and pressure in the boiler/condensate steam system, partial degradation into more volatile amines occurs.  The resulting blend of neutralizing amines provides the superior corrosion control of a blend of neutralizing amines from a single amine feed.  The preferred high molecular weight amine is dimethylaminopropylamine which will partially degrade into dimethylamine, trimethylamine, methylamine, and dimethylaminopropanol.     #37/mm
