Abstract: SURFACE HARDENING OF METALS USING ELECTRIC CURRENTS   ABSTRACT OF THE DISCLOSURE: Method and apparatus for modify-ing the surface properties of a metal part made of a metal which changes its properties with heating to a transformation temperature and subsequent cooling in which method electric current having a frequency of at least 3000 Hz is supplied to a pair of contacts respectively at the opposite ends of the surface area to be modified through a proximity conductor or conductors which are spaced from the surface area by not more than two times the width of the conductor.  The duration, frequency and magnitude of the current and the width of the proximity conductor or conductors are chosen so that the metal of such area heats at least to the transformation temperature before the adjacent metal reaches a temperature which would prevent self-quenching of the area metal, by means of conduction of heat from the area metal to the adjacent metal, when the current is discontinued.  Apparatus for producing lines of hardening on valve seats is disclosed.

Title: Centrifugal method and apparatus for processing  fluid materials
Inventor: FORSYTHE JESSE G JR
IPC: B04B5/04
Filed: 1979-03-30
Granted: 1982-05-18
Abstract: Abstract Samples to be analyzed, such as physiological fluids (blood, urine, etc.) may be processed using centrifugal techniques. The sample is centrifugally passed through a separation column to extract the desired component from the aqueous phase. Next, the extracted component is washed free of extraneous materials and then eluted from the separating column by centrifugally passing a suitable solvent therethrough. The aqueous phase and extracted components are collected in separate containers.      To faciliate this method, an apparatus is provided that accommodates switching between fluid flow paths in a centrifuge. The centrifuge utilizes a swinging bucket rotor which contains a separating column, the top end of which employs a fluid reservoir for holding the sample to be extracted. Fluids are passed through the separating column (a first flow path) from a central distributor in the centrifuge rotor while in operation. An outer ring of swinging buckets holds two receptacles (the second and third flow paths), one for the aqueous phase and one for the solvent phase containing the sample extract or physiological compon-ent. These two receptacles are place in radial fluidic alignment with the separating column by the technique of reversing the direction of rotation of the rotor, thus switching between two fluid flow paths.

Abstract: ABSTRACT OF THE DISCLOSURE      A noise reducer for a powder actuated fastening tool comprises a barrel including inner and outer cylindrical walls which are radially spaced to define a gas expansion chamber between them. The chamber is adapted to receive combustion gases through ports or passages in the inner wall, and the gases may be exhausted from the chamber in any appro-priate manner, preferably at a location adjacent the front end of the tool. The outer wall of the barrel can thus be made to slidingly fit within the tool receiver, while porting of the expansion chamber can be such as to induce a favorable flow pattern to the combustion gases passing therethrough.

Abstract: PATENT APPLICATION of GEORGE MIRAM for GRID COATING FOR THERMIONIC ELECTRON EMISSION SUPPRESSION                           Abstract In an electron gun having a control grid in contact with the face of the cathode, unwanted thermionic emission from the cathode can be effectively suppressed by applying a thin (1 micron) coating of boron nitride to the surface of the control grid.  The boron nitride has low thermionic emission itself and, in addition, has an unusual ability to shed or eliminate any deposits of emissive material such as barium or its oxides which come in contact with the boron nitride layer.  For optimum performance and longest lifetime, the boron nitride layer is applied over a pyrolytic graphite layer which may be the conductive grid itself.

Abstract: ABSTRACT         A system for producing television signals for displaying simultaneously a succession of time-separated images of an object moving over a selectable time period in an otherwise static scene which causes the latest image of the moving object to take precedence over the next previous image.  The system of the invention provides an improved display over that of a similar system described in Canadian patent application Serial No. 307,167, particularly in situations where there is partial overlap of successive images of the moving object; because the other system gives precedence to the earlier images, the latest image is partially occluded.  The improved system includes a reference frame delay, an update frame delay, a comparator, and a pair of multiplexers independently controlled in such a way that update information is not inserted in the reference frame delay during the "action interval", whereby to retain the integrity of the initially stored reference frame.  Separate control of the multiplexers allows capture of a reference frame at the start of the "action interval", and precludes information from being written into the reference frame during such interval, and following capture of the reference frame, causes update information resulting from comparisons of the immutable reference frame with selected subsequently arriving frames to be accumulated in the update frame delay.  As a result, earlier update information cannot obscure later update information; that is, the latest update information takes precedence over earlier update information.

Abstract: Abstract of the Disclosure A process for controlling emissions resulting from hot coke being discharged from an oven of a battery of coke ovens from the beginning of discharge until the time when the coke arrives at a quenching station.  The coke from the oven passes through a coke guide and a fume hood into an open-top, one-spot quenching car.  The hood covers the car during discharge and is connected to an exhaust system, including a gas cleaning device, which draws air into the hood in an amount sufficient to control emissions and for combustion of the volatile matter and other combustibles emitted from the coke during the time coke is discharged into the quenching car and for a short period of time thereafter.  During the movement of the open-top, one-spot quenching car from under the hood to the quenching station, the visible emissions given off by the hot-coke are less than 40% opacity.  The process can also be practiced with one-spot quenching cars of a different design, including a covered one-spot car that receives coke through an opening in the car.  Associated with the car is a gas exhaust-cleaning system which, as hot coke is discharged from an oven into the car, operates at a predeter-mined rate to draw air into the car in an amount sufficient to control emissions and for combustion of volatile matter and other combustibles emitted from the coke.

Abstract: Abstract Good salt rejection and flux characteristics can be obtained with reverse osmosis membranes made from crosslinked, interfacially polymerized aromatic polyamides, particularly poly(arylenepolyamine aromaticpolycarboxylamides) such as poly(phenylenediamine trimesamide).  The aromatic polyamides are preferably synthesized directly from an essentially monomeric polyacyl halide (at least tri- or higher in acyl functionality) and an essentially monomeric arylene polyamine with a measurable water solubility.  As compared to closely analogous linear polymers, these interfacially polymerized, crosslinked polyamides have a lower % elongation and lower solubility (e.g. in amide solvents). Chlorine resistance characteristics of these polyamides are also good and can be improved by treatment with a chlorinating agent.  In the preferred practice of the method for making a reverse osmosis membrane, a porous support latex is coated with the polyamine component (e.g. an aqueous solution of phenylene diamine); the thus-coated support is contacted with the polyacyl halide component (e.g. trimesoyl chloride), thereby initiating the interfacial polymerization in situ on the support; and the resulting product is dried to provide a composite membrane comprising the polyamide laminated to the porous support.
