Abstract: A local area augmentation navigation system for determining the location of an object using differential GPS. The system does not require any significant power or communication infrastructure. The system includes at least three reference stations, a master station and a LAAS receiver. The at least three reference stations are located in close proximity to each other and at known locations. Each of the reference stations receive a GPS signal from a GPS constellation and collect and output via a wireless transceiver the pseudo-range data from the GPS signal. The master station is positioned in close proximity to the reference stations and receives the pseudo-range data from the reference stations. The master station forms a correction message from the pseudo-range data and the known locations of the reference stations. The master station broadcasts the correction message within a specified area.

Abstract: A pan oiler for spraying oil into cavities in pans moving on a conveyor including a stationary center nozzle assembly and spaced outer nozzle assemblies. The outer nozzle assemblies are mounted on opposite ends of a drive screw having right hand threads formed on one end and left hand threads formed on the other end for moving the outside nozzle assemblies in unison relative to the stationary center nozzle assembly. A pair of electrically charged electrodes are positioned adjacent the nozzle assemblies for setting up an electric field across the spray paths of the nozzle assemblies for reducing overspray.

Abstract: A system for characterizing the pressure, temperature, movement and flow patterns of a fluid under high pressure within a test cell. The test cell is lined internally with adjustable rock facings. Pressure is measured within the test cell using a device employing pressure-distortable optical fibers. Fluid velocity, flow direction, and filter-cake buildup are measured with laser Doppler velocimetry. The flow pattern of the fluid is viewed using corresponding arrays of transmitting and receiving optical fibers. Temperature of the fluid is estimated using a combination of thermal sensors. The pressure, velocity, viewing and temperature systems are integral to the rock facings of the test cell.

Abstract: An electronic monitoring system to accurately measure a vacuum in an interstice between inner and outer walls of a dual-wall container or pipe which allows highly accurate analysis of vacuum differential to discover and confirm a leak in either the inner or outer walls of the container or pipe within minutes.

Abstract: The sequence controller disclosed is a microprocessor based unit having a user programmable sequence of electronic pulses for the control or synchronization of valves, relays, solenoids and timers. The controller is connected to spray nozzles adapted for projecting atomized droplets of liquid between charged electrodes in a timed sequence to cause the charged droplets to be attracted to and impinge against partial areas of a grounded surface to form a continuous substantially uniform film of liquid on the surface.

Abstract: A method of using a sequence control system in combination with a spray system for applying a liquid, such as cooking oil, to a surface of a pan carried by a conveyor. The controller, which is a microprocessor based unit, is connected to spray nozzles adapted for projecting atomized droplets of liquid between charged electrodes in a timed sequence to cause the charged droplets to be attracted to and impinge against partial areas of a grounded pan surface to form a continuous substantially uniform film of liquid on the surface.

Abstract: A method of forming a film of cooking oil on a pan surface wherein a mass of cooking oil is atomized to form droplets which are projected between a pair of electrodes having curved surfaces charged to a potential in a range between four and six kilovolts to electrically charge the droplets. The charged droplets are propelled at a velocity in a range between ten and twenty meters per second along a trajectory to impinge against an oppositely charged pan surface at an angle of greater than 45.degree. relative to the plane of the pan surface to form an oil film on the pan surface.

Abstract: A hydraulic splitter for cutting proofed dough pieces carried on a conveyor to form a chevron shaped pattern on the dough pieces. A manifold having multiple nozzles is movable along a guide rail by a timing belt driven by a stepping motor. The stepping motor is controlled by a computerized system in conjunction with a pan velocity sensor and a pan position sensor for initiating a cycle of operation and controlling movement of the manifold transversely of the conveyor. One of a plurality of stored programs is selected for controlling the shape of the pattern formed on the dough piece.
