Title: Microprocessor Controller for Diesel Fuel Fired Heater
Inventor: NELSON KIRK A
IPC: F23N5/20
Filed: 1994-06-29
Abstract: A diesel heater includes a combustion chamber and a fuel pump for pumping diesel fuel to the combustion chamber. An air supply device supplies combustion air to the combustion chamber. An igniter ignites the diesel fuel to generate combustion heat. A heat exchange fluid supplying device supplies fluid in heat exchange relationship with the combustion heat. A thermal sensor in contact with the heat exchange fluid generates a temperature signal related to the temperature of the heat exchange fluid. A flame detector detects an ignited diesel fuel flame and generates a flame signal in response thereto. A microprocessor includes a memory and a plurality of input/output ports wherein the input/output ports are electrically connected to the thermal sensor, the fuel pump, the heat transfer fluid supplying device, the igniter, the combustion air supply device, and the flame detector. The memory stores a normal operating sequence, a start-up sequence, and a fail start period for the start-up sequence. An input device allows the current day and current time to be entered into the microprocessor memory. The microprocessor thereafter updates the current day and current time. A lower threshold temperature for the heat exchange fluid is entered into the microprocessor memory by the input device. A start day and start time are also entered into the microprocessor memory by the input device. The microprocessor automatically initiates the start-up sequence when the heat transfer fluid falls below the lower threshold temperature or when the current day and the current time equal the start day and the start time. The microprocessor executes the normal operating sequence when the flame signal is received.

Abstract: A line blind valve is disclosed which includes a housing having opposed similar housing halves with resilient sleeve units which compressibly engage each other in the valve open condition and engage opposite sides of the gate or blind in the valve closed condition.  The line blind valve provides visibility of all gate edges so as to give a positive indication that the gate or blind has passed completely through the seals.  Lockout is also provided when the gate or blind is closed.  Each sleeve unit has a plurality of compression holes extending axially and arranged at intervals relative to the circumference of  the  sleeve.   An encircling stiffening ring of harder material is encapsulated in each sleeve so as to be positioned at the inner end of the compression holes.  The line blind valve construction of the present invention results in no leakage to the outside when the valve is fully open and no leakage to the outside or past the gate internally when the valve is fully closed.

Title: Method and apparatus for treating cardiac tachyarrhythmia
Inventor: PLESS BENJAMIN D
IPC: A61N1/39
Filed: 1995-02-09
Abstract: The present invention provides an apparatus and method for cardiac defibrillation which utilizes a lower voltage defibrillation output to depolarize the myocardial cells by providing a rapid sequence of defibrillation shocks synchronized with sensed sequential cardiac events or features during an arrhythmia. Each shock may be a conventional monophasic or biphasic pulse. Each of the shocks may be relatively short in duration, i.e. on the order of 0.5 to 3 milliseconds or may be relatively long, i.e. up to about 100 milliseconds. The amplifiers of the sensing circuitry are particularly adapted quickly recover to after each shock is delivered to allow synchronization of the next shock to the next cardiac feature. This is accomplished by using broad band amplifiers which have DC-baseline restoration capability in order to eliminate offsets caused by a preceding shock. A microprocessor in the pulse generator delivers a programmed number of pulses synchronized to the ECG. If a first sequence fails to terminate the arrhythmia, another sequence is delivered at a higher voltage and/or additional pulses are added to the sequence.

Patent CA-2144251-A1 (CA)
Title: Improved acoustic displacement flowmeter
Inventor: WOODWARD WILLIAM S
IPC: G01F3/20
Filed: 1995-03-09
Abstract: An acoustic displacement flowmeter determines the flow rate of a fluid in a path containing a controllable valve by establishing fluid flow along the path, directing the flow of the fluid to a transducer having a displacement element by restricting the flow path, generating a signal from the transducer representative of displacement due to fluid flow while the flow path is restricted, using the transducer to determine the fluid flow rate, and reestablishing fluid flow along the path by removing the restriction. The transducer signal is used to determine the fluid flow rate by providing an analog reference signal, integrating the analog reference signal for a predetermined time period, deintegrating the integrated reference signal with the transducer signal until the value of the deintegration signal reaches a threshold value, and using the time required for the deintegration signal to reach the threshold value to calculate the flow rate. The time is accumulated by counting the number N of fundamental sampling periods occurring during the deintegration of the integrated reference signal and determining the flow rate from the equation V = A/N-B, where V is the mass flow rate and A and B are constants. A temperature correction signal for adjusting the calculated flow rate value for temperature variations is generated by providing first and second sensor signals whose ratio is representative of temperature, integrating the first sensor signal for a predetermined time period, deintegrating the integrated first signal with the second sensor signal until the value of the deintegration signal reaches zero, and using the time required for the deintegration sensor signal to reach zero to calculate the temperature correction signal.

Title: Multiplexed trailer light system
Inventor: VINCENT RAYMOND A
IPC: B60R16/03
Filed: 1995-04-27
Abstract: An encoder and decoder (multiplexer and demultiplexer) are used to control the rear operating lights (e.g., turn, brake, or running lights) of a trailer towed on the roads behind a tractor vehicle. Voltages powering the tractor vehicle's rear lamps are the inputs to a combinational logic unit with gates (AND, OR, etc.) for interfacing between different lighting systems on the tractor and trailer. The logic unit's outputs are fed to an encoder which converts the parallel outputs to aerial data. The data are sent over a single wire to the decoder, mounted on the trailer. The decoder regenerates the parallel signals to control switches (power transistors) driving the trailer lamps with power from the vehicle battery.

Fault tolerant functions are provided for allowing an application process to generate a heartbeat message at specified intervals indicating that the application process is still active.  In addition, fault tolerance implementation functions are provided for specifying critical memory, for executing checkpoints to store backup copies of critical data, and for restoring critical data during a recovery.  In addition, functions are provided which process messages that are sent or received by an application process and maintain logs of the sent and received messages.  The progressive retry recovery method consists of a number of retry steps which gradually increase the scope of the rollback when a previous retry step fails.
