Abstract: RCA 71,833 TELEVISION RECEIVER PROTECTION CIRCUIT                  Abstract Of The Disclosure A deflection circuit of a television receiver produces scanning current in a deflection winding.  The deflection circuit includes first and second terminals at which                      first and second deflection rate voltages are developed.  The first deflection rate voltage incudes under fault conditions a fault component voltage present during at least a portion of a deflection cycle.  The fault component voltage is substantially absent from the second deflection rate voltage.  A protection circuit includes combining means coupled to the first and second terminals for combining the first and second deflection rate voltages for producing a fault signal at a third terminal under fault conditions.  A circuit responsive to the voltage developed at the third terminal provides a disabling signal for disabling normal television receiver operation when the fault signal is present.

Abstract: Abstract:      A method of applying a surface layer across a surface layer or joint between cladding layers on a clad metal plate or plates comprises  forming a shallow chamfer along each opposing cladding layer edge and positioning over the said chamfers a corrosion resistant metal flyer-plate having a shallow generally V-shaped configuration, optionally applying a buffer layer of transmitting medium placed on the outside surface of the flyer-plate, further superimposing an explosive layer upon the cladding and buffer layers and detonating the explosive layer so as to weld the flyer-plate material at least to the cladding layers.  Advantageously a metal groove may be formed in the base metal layer of the clad plate to facilitate positioning of the flyer-plate, the groove wall conveniently being extensions of the cladding chamfer surfaces.     The method facilitates an assembly of a cladding strip and explosive layer over a joint between clad metal plates in any orientation and gives joints of high quality between the cladding layers on the plates.

Abstract: Dispositif de mesure des contraintes appliquées à une  garniture de forage.  Il comporte des moyens de mesure associés à un organe élastique reliant deux conduits adjacents qui se raccordent respectivement à une section supérieure et à une section inférieure de la garniture de forage.  Un manchon protège l'organe déformable contre la pression radiale externe. Selon l'invention les conduits ont sensiblement même diamètre externe à leurs extrémités adjacentes, et le manchon et l'un des conduits constituent les parois latérales d'un espace annulaire dans lequel est logé un piston annulaire intermédiaire limité par des éléments annulaires formant les parois d'extrémité dudit espace.  Les éléments annulaires sont solidaires d'une première desdites parois latérales et coulissent sur la seconde paroi, tandis que le piston est solidaire de la seconde paroi et coulisse sur la première.  Le piston sépare deux chambres annulaires dont l'une communique avec l'espace extérieur à la garniture et l'autre avec l'espace intérieur. Les sections droites annulaires efficaces des chambres de part et d'autre du piston sont choisies en fonction des valeurs du plus petit diamètre de l'espace annulaire aux niveaux respectifs des parois d'extrémité de cet espace, de façon à éliminer sensiblement toute contrainte axiale pouvant résulter d'une différence de pression entre l'intérieur et l'extérieur de la garniture.

Abstract: ABSTRACT OF THE DISCLOSURE           Electroless copper deposition solutions, and method of continuously electrolessly depositing copper onto a workpiece using these solutions, are disclosed. The solutions contain, in addition to water as the usual solvent, a soluble source of copper ions, a complexing agent or mixture of agents to maintain the copper in solution, a non-formaldehyde copper reducing agent, such as hypophosphite, effective to reduce the copper ions to metallic copper as a deposit or plating on a prepared surface of a workpiece brought into contact with the solution, and a soluble source of non-copper metallic ions, such as nickel or cobalt ions, which act as an autocatalysis promoter to enable continuous plating using the solutions.  The solutions are maintained in an alkaline condition and preferably in a pH range of 11-14 through the addition of pH adjusters.  The properties of plating baths using the solutions, such as  bath stability as well as plating process parameters such as plating rate, and the quality of deposit may be advantageously controlled through the appropriate selection of the non-copper metallic ion added and the complexing agent used. Optional additives, such as polymers, wetting agents, and various soluble unsaturated organic compounds, may also be utilized to influence these variables.

Abstract: Abstract of the Disclosure Strap feeding and tensioning apparatus is pro-vided for use in a strapping machine to feed steel or plastic strapping in a loop around an object to be strap-ped and tension the strap loop about the object, provid-ing maximum gripping force on the strap and minimum mar-ring thereof.  The apparatus includes a motor-driven drive wheel geared to a feed wheel, the drive wheel and feed wheel respectively having circumferential strap-engaging surfaces which cooperate frictionally to grip the strap-ping therebetween and move the strapping in a tensioning direction in response to rotation of the drive wheel. The axis of rotation of the feed wheel is shiftable about a fixed axis to accommodate movement of the feed wheel toward and away from the drive wheel, tensioning of the associated strap exerting a resultant force on the feed wheel tending to effect movement thereof about the fixed axis in a direction to increase the frictional gripping force exerted on the associated strap by the feed wheel and the drive wheel.  The axes of the drive and feed wheels lie in a plane disposed at a predetermined angle of less than 26 degrees with respect to a plane defined by the fixed axis and feed wheel axis.  For use with steel strap the strap-engaging surfaces of the drive and feed wheels are substantially smooth and the predetermined angle can be as low as about 6 degrees. For use with plastic strap-ping the drive wheel has a toothed or knurled strap-en-gaging surface and the predetermined angle can be as low as about 12 degrees.

Abstract: ABSTRACT         A novel coupling means for coupling elongated drill rod sections together and a novel method for assembly and disassembly of such sections is disclosed.  The coupling means utilizes a body which can receive and secure a drill rod section in each end and external portions engageable by a tool.  The external portions include enlongated flats extending from each end so that as the body rotates a tool engaging the flats can move axially relative to the body.          In the method all coupling means are initially loosened and then the drill motor tightens the coupling means connected to the uppermost drill rod section.  The motor is then operated to release the uppermost drill rod section from the next lower drill rod section.  The uppermost drill rod section is moved to a rack, is disconnected from the motor and deposited in the rack.  The motor is then connected to next uppermost drill rod section and the process is repeated until the drill string is completely disassembled.  The method is performed in the opposite sence when assembling the drill string.

Abstract: ABSTRACT     This sewage and waste water treatment system introduces a different approach to the usual biological digestion of organic solids and sterilization thereof in the effluent.  -It proceeds from the concept that all sediments and suspended solids to 20 microns or less are removed immediately and continuously from the in-flow, and the almost suspended solid-free flow therefrom is treated in a unique manner with ozone so as to react chemically with the dissolved and remaining suspended solids by oxidation to produce precipitations, gasifications and sterilization which in turn are removed from the system immediately and continuously to 5 microns or less, thus greatly reducing the ozone requirements for the oxidation reactions.  The liquid effluent discharged from this process is a clear and sterilized liquid having no contaminants harmful to biological life.    The system also includes the treatment of the removed solids from sewage with ozone to produce a completely deod-orized and sterile product without the requirement of substan-tial chemical oxidation reactions, thereby reducing the ozone demand, and further treatment of the solids in such a manner so as to produce useful dry commercial fertilizers containing a maximum amount of non-pathogenic soil microorganisms required to sustain plant life.      The steps herein are performed largely by existing equip-ment of proven ability with a minimum of moving parts.  The ozone treating method can be applied to liquids and liquids containing a substantial amount of suspended solids in compara-tively large and varied particulated sizes.
