Title: Female electrical plug with overload protection
Inventor: KOVACIK JAMES D
IPC: H01R13/713
Filed: 1992-02-13
Granted: 1996-08-06
Abstract: A female electrical plug includes a pair of female terminals for engaging prongs of a male electrical plug, a female ground terminal, and a circuit breaker providing a path for electrical current and being responsive to electrical current flow in excess of a predetermined amount for opening the path and preventing the current flow, the circuit breaker having a reset button manually actuatable for closing the path. The plug also has a first conductor connected in series with the circuit breaker to one of the female terminals, a second conductor connected to another one of the female terminals and a third conductor connected to the female ground terminal. A body formed of an insulating material encapsulates the female terminals, the female ground terminal, the conductors and the circuit breaker. The body has a generally planar front surface with a pair of prong shaped apertures formed therein providing access to the female terminals and a ground prong shaped aperture providing access to said female ground terminal. Another aperture is formed in a side surface of the body through which the reset button extends and a pair of guard walls are formed on the side surface on opposite sides of the reset button for protecting the reset button from damage during normal use. An additional two sets of pairs of female electrical terminals and a female ground terminal can be encapsulated in the body on opposite sides of the two female terminals and connected in parallel accommodate three male plugs.

Title: Supercritical fluids as diluents in combustion of liquid fuels and waste materials
Inventor: NIELSEN KENNETH A
IPC: F23G7/04
Filed: 1992-03-27
Granted: 1997-09-09
Abstract: The present invention is directed to processes and apparatus in which supercritical fluids are used as viscosity reduction diluents for liquid fuels or waste materials which are then spray atomized into a combustion chamber.  The addition of supercritical fluid to the liquid fuel and/or waste material allows viscous petroleum fractions and other liquids such as viscous waste materials that are too viscous to be atomized (or to be atomized well) to now be atomized by this invention by achieving viscosity reduction and allowing the fuel to produce a combustible spray and improved combustion efficiency.  Moreover, the present invention also allows liquid fuels that have suitable viscosities to be better utilized as a fuel by achieving further viscosity reduction that improves atomization still further by reducing droplet size which enhances evaporation of the fuel from the droplets.

Title: Servo tracking for helical scan recorder
Inventor: HUGHES TIMOTHY C
IPC: G11B15/467
Filed: 1990-11-06
Granted: 1995-09-19
Abstract: In a servo tracking method and apparatus, a servo head (S) of a helical scan recorder (30) endeavors to travel equidistant between two servo signal-bearing stripes recorded on the tape (32). The recorder (30) determines a reference-crossing time at which the servo head (S) begins to cross a horizontal reference line (606) drawn with respect to the beginning of a stripe on the tape (32). The servo head (S) samples the amplitude of a servo signal provided on the tape (32) at a plurality of predetermined times after the reference-crossing time. A servo tracking circuit (175) uses the amplitudes of the servo signal at the predetermined sampling times to determine how to adjust the position of said head (S) relative to the pitch of said stripe.
Patent CA-2067583-C (CA)
Title: Arrhythmia detector using delta modulated turning point morphology of the ecg wave
Inventor: HSUNG JEAN-CHEUI
IPC: A61B5/364
Filed: 1992-04-29
Granted: 1996-06-25
Abstract: An arrhythmia detector includes a delta modulator which digitizes the ECG signal and produces a serial digital signal that represents the input ECG signal.  A microprocessor classifies the signal as having no slope, positive slope, or negative slope.  A finite state machine model in the microprocessor uses the positive slope, negative slope, or no slope information to determine the number of times an isoelectric line segment is present in the ECG signal.  By accumulating the line-counts or number of line segments over a two-second period, a determination can be made whether the ECG signal has been in isoelectric line less than a threshold.  For two out of three 2 second periods, if the percentage of isoelectric time is less than the ventricular fibrillation threshold then a ventricular fibrillation signal can be generated.  For ventricular tachycardia verses supraventricular tachycardia discrimination, a second threshold which relates to the average heart rate observed in a linear formula LC(TH) = b - a*(rate)/30 can be used.  If the isoelectric line-count is less than the LC(TH), then VT is declared.          The regression coefficient a and b can be found by measuring the line-count and rate pairs in 2 second periods during normal sinus rhythm in periodic basis, for example, 10 data pairs every hour. The delta modulator uses a comparator which receives the ECG signal and a tracking signal to output a series of binary digits.   A digital-to-analog converter generates the tracking signal.

Abstract: Pouring devices for accurate blending of colour tinters to a base paint are known, but are generally of metal construction comprising a spout covered by a movable cover plate.  Such devices produce accurate pouring due mainly to the rigidity of the metal components.  The invention enables an accurate pouring device to be produced from plastics material. The pouring device comprises essentially two plastics components, a cover plate (3) and operating means (4) therefor being integral and providing one component and a spout (10) formed integrally with a support body (1) providing the other component.  Connection means (6) are provided for detachably connecting the support body over an aperture (20) of its liquid container.  The support body base (5) is elongate and engages over an extended area of the adjacent container wall (19) to provide a stable support and absorb loads applied during use. The connection means may include a threaded boss (25) forming part of a collar (21) which can be snap fitted into a standard-sized aperture, whereby the device can be used for a range of different sized and/or shaped containers.

Title: Apparatus and method for spot position control in an output device employing a linear array of light sources
Inventor: PAOLI THOMAS L
IPC: H04N1/12
Filed: 1992-09-09
Granted: 1998-07-28
Abstract: In a method and apparatus for raster scanning optical output device, such as a laser printer or the like, an array of independently addressable light emitting devices, such as an array of solid state lasers, is used to control spot position on an image plane in the slow scan direction. The array is disposed such that the spots emitted from each element of the array impinge the image plane displaced in the slow scan direction from one another. The total distance between all the spots is less than the distance between fast scan direction scan lines. Only a single element of the array is operated per scan line, thus only a single spot is formed on the image plane per scan line. Control of which of the elements of the array emits a light beam per scan line allows control of the spot position in the slow scan direction for that scan line.

Title: Two line pilot valve
Inventor: JOHNSON CLARENCE WILLIAM
IPC: F15B21/04
Filed: 1993-02-05
Granted: 1999-08-31
Abstract: A two line pilot valve used to exhaust hydraulic fluid from a control circuit when the operating conditions within which a flowline is intended to operate are outside of predetermined limits. The pilot exhausts fluid within a control circuit to a reservoir which allows a dump valve to dump fluid from an actuator which causes the actuator to close the flowline. The pilot has a first poppet sleeve which contacts an o-ring. When the poppet sleeve and o-ring separate, fluid is allowed to pass from the inlet port of the pilot to the exit port and thereby exhaust the fluid of the control circuit.
