Title: Programmable controller vision system
Inventor: GASPERI MICHAEL L
IPC: G05B19/05
Filed: 1988-05-18
Granted: 1994-01-11
Abstract: Abstract A module for a programmable controller is adapted to process a video image to evaluate characteristics of an object within the image.  A processor converts an analog video signal into four binary images.  A memory stores data defining a separate sensor region for each binary image.  A set of four counters is provided to tabulate the pixels of one color in each binary image that lie within the associ-ated sensor region.  A video signal sensor measures vari-ation of the luminance of the video signal.  The processor uses the luminance variation measurement to adjust the bi-narization of the video signal to produce normalized binary images under varying lighting conditions.

Title: Method for prepressurizing dispensing container and for filling pressurized container with flowable product
Inventor: BANKS GORDON L
IPC: B65D83/00
Filed: 1988-09-09
Granted: 1992-03-03
Abstract: Abstract of the Disclosure A pressurization pouch having a pressurization system therein activated by the application of a vacuum underpressure to the outside surfaces of the pouch is inserted into a dispensing container through an opening in a lid portion of the container. Upon the sealing of the container by the attachment of a valve member to the container lid at the opening thereof, a vacuum gen-erator is coupled to the valve member to generate negative pres-sure inside the dispensing container, thereby causing the pouch to expand under the pressure of a predetermined amount of air disposed therein.  Upon that initial expansion, the pressuriza-tion pouch is further inflated owing to the action of the pres-surization system.  Upon complete inflation of the pressurization pouch, the pouch forms a liner in the dispensing container.  A flowable product is then injected into the dispensing container through the valve member.   The pouch comprises a pair of com-partments releasably sealed and separated from one another by a seam having a sharp point formed by a pair of straight-line seam segments joining one another at an acute angle.

Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed are shaped or unshaped refractory compounds based on extremely pure, low-iron magnesite material in admixture with a zirconium compound, particularly zirconium dioxide, and their use, particularly in the form of burnt moulded bodies or refractory bricks, for lining furnaces or high temperature zones of furnaces for the manufacture of burnt dolomite, burnt lime or burnt magnesite.  The refractory compounds according to the inven-tion are characterized by the fact that they contain as magnesite sintered or fused magnesite with a purity of at least 97% by weight of MgO and as admixture 10 to 25% by weight of a zirconium compound with a ZrO2 content of at least 98% by weight, based on MgO.  The advantage of the refractory compounds according to the invention lies therein that they can be readily used in furnaces at burning temperatures above 1900°C, whereby they exhibit excellent stability of volume, chemical resistance to the charging material and structural flexibility, and furthermore, make lining with bricks without joint grouting possible.

Title: Magnetron with microprocessor power control
Inventor: SMITH PETER H
IPC: H05B6/68
Filed: 1988-12-15
Granted: 1992-12-22
Abstract: MAGNETRON WITH MICROPROCESSOR POWER CONTROL ABSTRACT OF THE DISCLOSURE      A microwave oven uses a full wave full bridge inverter for supplying energy to a cooking magnetron by way of a power transformer.  The inverter is controlled by a microprocessor which acts upon a control circuit having an oscillator.  The control circuit provides gating pulses which are used to switch on FET switches in the inverter.  The microprocessor stops and starts the gating pulses.  The microprocessor may adjust the power of the magnetron by turning the control circuit on and off for variable time intervals.  Alternately, the microprocessor may control the power of the magnetron by changing the switching frequency of the inverter.  The microprocessor is used in a filament standby mode to monitor the current in the magnetron's filament.  In the filament standby mode, the inverter is operated at a lower than normal voltage such that the magnetron is not generating microwave power, but its filament is receiving sufficient current to warm it up, the current flowing through a filament winding of a power transformer.  A primary winding of the power transformer is connected to the inverter.

Abstract: A fluid container (1) with a dosage assembly (3) for delivering a metered amount of fluid through an outlet opening (32) when the container is turned 180°.  The dosage assembly (3) comprises a plunger (20) moving during the metering of the dosage between a start position, providing a free passage for the fluid between the outlet opening (32) and the fluid in the container, and a position, where the plunger (20) blocks this passage and thus the outflow of fluid.  Furthermore the dosage unit comprises a timer chamber (15) defined by the plunger (20) and having a timer aperture (16) for controlling the movement of the plunger (20) from its start position to its blocking position by means of the flow of fluid.  The aperture (16) of the timer chamber (15) is connected with a passageway between the outlet opening (32) and the interior (19) of the container, and that the timer chamber (15) has a feed opening (18) being connected with the interior (19) of the container when the plunger (20) is in its start posi-tion.  As a result the timer chamber is substantially momentarily filled with a fluid through the feed opening, when the container is turned 180° and gradually emptied during the movement of the plunger towards its blocking position so that the timer chamber is substantially empty when the plunger has reached its blocking position and the dosing process is finished.  This causes the plunger to quickly drop to its start position, when the container is returned to its vertical position, as no fluid has to be dis-placed from the timer chamber.  This enables a fast repetition of exact fluid dosages.

Abstract: ABSTRACT           TRANSMISSION LINE INSTALLATION      A method and apparatus for installing optical fibers (11) in tubes or ducts (29). An optical fibre is fed from a reel (13) into a small diameter feed portion of duct (25), and compressed air is introduced into the duct. This advances the fibre, using viscous drag forces, into a main duct of larger diameter. There is a pressure drop at the intersection of the two ducts. Subsequently, the advancement of the fibre is continued by maintaining the air supply, and the viscous drag forces, acting on the increasing length of the fibre in the duct, advance it along the duct. Two or more fibres, which may be unsheathed primary coated fibres, may be installed simultaneously.

Title: Rotary paint atomizing device
Inventor: WEINSTEIN RICHARD
IPC: B05B7/08
Filed: 1989-07-21
Granted: 1995-04-04
Abstract: An improved rotary paint atomizing device in the form of a bell and a cover plate which is releasably attached to the front center of the bell.  Paint fed along the axis of the device onto a conical projection on the back surface of the cover plate accelerates and flows outward in a radial direction.  The cover plate surface is curved so that as the paint flows outwardly, it also flows first forward and then back until it reaches radial slots formed in a peripheral rim on the cover plate where the cover plate contacts an interior bell surface.  Paint discharges from the slots onto a conical interior bell surface and flows in wide, closely spaced ribbons which merge into a uniform, continuous thin sheet before it is discharged from the bell edge. As the paint discharges from the bell edge, the sheet produces extremely fine uniform ligaments which break up to produce fine, uniform small paint particles.
