Abstract: D.F. Winter  - W.K. Dick 2-1 ELECTRONIC GROUNDING SYSTEM FOR ELECTRICAL DISTRIBUTION          Abstract Of The Disclosure:       A grounding system for grounding the neutral conductor of an electrical distribution system.  A point of reference potential with respect to true earth ground potential is provided.  An amplifier has a first input connected to the reference potential and a second input connected to the grounded neutral conductor.  The amplifier provides an output signal indicative of the difference between the undesired stray voltage on the grounded neutral conductor and the reference potential. The amplifier develops the output signal across the secondary winding of an output transformer.  One terminal of the output transformer is connected to the grounded neutral conductor of the distribution system.  The other output terminal of the transformer is connected to true earth ground by way of an auxiliary ground path having a finite resistance.  The grounding system thus reduces the magnitude of the neutral-to-earth voltage, including transient variations thereof  to a value approaching  or more nearly equal to  true earth ground potential.

Abstract: ABSTRACT OF THE DISCLOSURE               A spiral gas stream is generated in a pipeline when a uniform flow of gas flowing in a cylinder having inner diameter larger than that of the pipeline is introduced through a funnelform reducer into the inlet of the pipeline and bringing the mean gas stream velocity in the pipeline faster than 20 meter per second.  The uniform flow of gas is formed in the cylinder easily when outside low pressure gas is fed into the cylinder through a feed gas inlet pipe installed diagonally at the side of the cylinder apart from the bottom plate so as to make the flow line of the feed gas to cross the axis of the cylinder and inclined toward the bottom plate.  When solid particles are introduced into the spiral gas stream zone, they are transported to the outlet of the pipeline.  As the compressed gas layer is formed along the inside wall of the pipeline by the spiral motion of gas stream, solid particles do not directly contact the inside wall of the pipeline to cause wear.  As the center part of the cross section of the pipeline becomes very low pressure, especially along the axis of the pipeline, solid particles containing or accompanying volatile matters are desiccated or concentrated as a result of the evaporation of volatile matters while being transported in the pipeline.  Solid particles deposited on the bottom of water can be dredged and dehydrated by the spiral gas stream transportation system. When solid particles transported by spiral gas stream in two or more pipelines are arranged to collide, pulverized fine solid particles are recovered.  A chemical reaction which can not or hardly to proceed at normal temperature and pressure is promoted in a spiral gas stream zone.

Abstract: A B S T R A C T          In this invention a forced air, oil-fired, central home-heating fur-nace is modified by a draft valve installed in an outside wall of its return air chamber.          Operation of such draft valve is synchronized with operation of the furnace fan, so that the draft valve is closed when the furnace fan is in operation, but open during the periods when the furnace fan is at a standstill, allowing thus ambient indoor air to enter the hea-ting system extract residual heat, and transfer it into an upper heated space by means of natural convection.          Such modification reduces waste of residual heat, without causing counter-productive effects of continuous forced air circulation.

Abstract: WELL TOOL LOCKING APPARATUS                    ABSTRACT OF THE INVENTION      A clamping apparatus for locking tools in a well is disclosed.  A first piston sealable engages a hollow body member to form a chamber, which is filled with a working fluid.  A bias member or spring moves the first piston, extending a clamping arm connected to the first piston against the well wall.  A second piston is sealable engaged in a bore in the first piston; the bore is in fluid communication with the chamber.  The second piston is driven into the bore by a motor, increasing the pres-sure in the chamber through a passage in the first piston between the bore and the chamber.  This increased pressure further urges the first piston and locks the clamping arm against the well wall.  The hydraulic pressure is released, and the clamping arm is unlocked, by opening a valve in a line between the chamber and a reservoir.  The clamping arm is retracted by driving the second piston into the bore into contact with the first piston, forcing the first piston back against the spring.

Abstract: PUMP-LESS PAINT SPRAY BOOTH A wet pump-less spray painting booth is provided that more efficiently removes over spray paint particles from the air and uses substantially less make-up water than prior designs of wet pump-less booths. In a rear air cleaning section of the booth, blower-generated air flow sucks water from a lower reservoir up through ducts into an upper plenum where the air and water impact against a splash plate, creating a turbulent mix of air and water. Water from the upper plenum drains through tubes to an upper reservoir and overflows the upper reservoir along a sheet, the bottom edge of which is spaced a substantial distance from the lower reservoir, creating a water curtain. Air flow is through a user portal where the air becomes laden with overspray paint particles, through the water curtain below the sheet at a relatively low velocity to partially clean the air of paint particles, upward through the ducts, into the turbulent mix of air and water where the air is further cleaned and upward through the plenum to an exhaust. The water curtain, which is generally uniform due to the low velocity of air flow there through, and the turbulent mix of air and water at the splash plate provide sufficient air-water contact to remove over 99% of the paint particles from the air. Very little water is exhausted with the air due to the splash plate interdicting the upward path of water through the plenum and due to substantial reduction of air velocity in the plenum as a result of the plenum having a much greater cross-sectional area than the ducts.

Inventor: BROCK GREGORY K
IPC: G01B17/00
Filed: 1983-10-06
Granted: 1988-01-12
Abstract: ABSTRACT OF THE DISCLOSURE The invention is a method and apparatus for non-contact measurement of the length and height or diameter of geometrically regular objects. The objects enter a first measurement station where horizontally opposed echo ranging transducers make sequential differential measurements to deter-mine the length and transverse position of the object. Position information is sent to a microprocessor. The object is then advanced under a transverse array of downwardly oriented echo ranging transducers. The microprocessor preferably selects the single transducer located most closely to the mid-length position of the object to make a height or diameter measurement. In the case of cylindrical objects, the object should be oriented with its axis parallel to a line projected between the opposed length measuring transducers. As the object is moved by the diameter sensing transducer, the microprocessor selects the measurement indicating the shortest distance between the object and the transducer. Diameter of the object can then be readily determined. The invention is particularly well adapted for measure-ment of objects that may be randomly located across a moving conveyor system.
