Abstract: ABSTRACT OF THE DISCLOSURE         The surface of a metal article which is exposed to the atmosphere and abrasion during normal use of the article  is  protected  from  scratches  and/or  corrosion during such use by a thin transparent abrasion-resistant film of an inert non-metallic material such as SiO2, SiC, Si3N4,  TiO2, MgO, Al2O3, Ta2O5, Nb2O5, GeO2 ,  spinel and selected colorless  glass  compositions.   The  protective film is preferably deposited by RF-sputtering techniques and undesirable coloration of the article by optical in-terference effects from incident light rays is avoided by properly correlating the film thickness with the refrac-tive index of the particular material used to form the film.  The  invention  permits  the  use  of  thinner  gold plating on such items as articles of expensive jewelry and bracelets and cases for fine wristwatches without detract-ing  from the  quality,  durability or  appearance of the merchandise.   Alternative  embodiments  in  which  several films of various selected non-metallic inert materials are combined to form composite protective coatings that pro-vide additional cost and manufacturing advantages are also disclosed along with methods for sputter-depositing the protective films in the proper thicknesses to avoid op-tical discoloration effects, either on articles that have been previously plated with gold or which have been pro-vided with a sputter-deposited layer of gold by sequen-tially operating the sputtering apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE       In a device for regulating the air supply of an internal combustion engine supercharged by a turbo-compressor unit driven in rotation by the engine's exhaust, the intake of the rotating compressor is controlled by an intake regulation (or gating) system capable of reducing the compressive effect of the rotor of the compressor.  Control elements of said regula-tion (or gating) system are connected with the accelerator linkage so as to close the regulation (or gating) system and reduce the compressive effect to the maximum degree when the accelerator moves toward the idling position of the engine.

Abstract: SEPARATING COLLECTOR FOR SUBSEA BLOWOUTS                           Abstract A collector apparatus and method for use with a blown-out seabottom wellhead comprising a plurality of collector elements each having an extended, open base and an upper portion enclosing a volume to receive fluid comprising gas and lesser quantities of oil rising, in the water, from the wellhead, and risers connected to the collector elements and extending thereabove to conduct fluid therefrom.  One collector element is disposed below at least one other collector element with an open volume defined therebetween, the first element positioned to intercept fluid rising from the wellhead, and the second element positioned to receive and collect excess flow of fluid that is not collected by the first element.  A riser extends from the first collector element to the surface of the sea, and a second riser extends from the second collector element to a storage tank above the second collector element.  The first riser includes an adjustable valve adapted to restrict flow through the riser whereby only a portion of gas from the blown-out wellhead is allowed to flow through the first riser and a further portion of gas and oil are rejected by the first collector element and flow into the second collector element, and the second riser is adapted to conduct gas in a gas-lift pumping flow rate capable of carrying water and accompanying oil from the second collector element to the storage tank.

Abstract: Abstract of the Disclosure A source of a duobinary data signal is connected to a remote point by a coupling network having a high pass characteristic and transmission line.  The data signal received at the remote point is subtracted from a delayed version thereof to derive the change representative signal, which is utilized at the remote point to regenerate and/or detect  code violations of the data signal. Preferably, the received data signal is subtracted from a version thereof delayed by one bit time period. Circuitry generates an indication of a violation when; after assuming one extreme level in a given bit time period, the change representative signal again assumes the same level before assuming the other extreme level during a bit time period separated by an odd number of bit time periods from the given bit time period. Circuitry may also convert the change representative signal back to the duobinary data signal.  Specifically, a three-state reversible binary counter is stepped up one state each time the change representative signal assumes its high level, is stepped down one state each time the change representative signal assumes its low level, and remains unchanged in state each time the change representative signal assumes its intermediate level.

Abstract: ABSTRACT:           In order to increase the resonance frequency of a transformer, the secondary winding is divided into several (identical) coils, which are each connected to a corresponding individual bridge rectifier circuit.  The outputs of the bridge rectifier circuits are connected in series and each coil is wound in a sense opposite to that of the immediately adjacent coil(s).  Each coil is divided into two series-connected sections, which are each wound in a corresponding individual winding compartment of the coil former.  The series connection between the two coil sections extends through a passage on the bottom of the partition wall between the two winding compartments.  Con-sequently, the coil ends are located on the outerside of each coil section, as a result of which a simple connection (with short connecting leads) is possible.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus is disclosed for the forming of metal, more particularly for the forming of objects made from strips of metal.  The apparatus comprises a base block which has a flat, horizontally-oriented, planar upper surface adapted to receive a forming die; a top block assembly that includes a lower member having a flat, horizontally-oriented, planar lower surface that is oriented parallel to said upper surface of said base block and is movable as to proximity with respect thereto and vertically-oriented hydraulic press means for imparting selected amounts of bias to said top block against it being impelled away from said base block.  A roll assembly is positioned between the lower surface of the top block and the upper surface of the bottom block.  This assembly comprises two contacting cylindrical rolls which are oriented with the axes of said rolls parallel to each other and to both said lower surface of said top block and said upper surface of said bottom block and which describe a fictitious plane per-pendicular to said surfaces and which are supported by roll support means, said roll assembly means being free to move along a path perpendicular to said ficti-tious plane.  Horizontally oriented hydraulic motion means are provided for causing the roll support means and the rolls to move along a path which is parallel to said surfaces and perpendicular to said fictitious plane.  Stop block means are provided for positionally limiting the proximity of said sur-faces with respect to each other to a distance equal to the collective diameters of said two rolls.  With the apparatus described above a strip of metal-forming stock may be positioned above a forming die positioned in the base block and an object of desired configuration and dimension may be produced by causing at least one reciprocation of said roll assembly through operation of said motion means while said roll assembly is biased against deflection upward in excess of pre-determined amounts along the path described by said fictitious plane in response to coming into contact with said strip as said assembly reciprocates by means of biasing pressure applied to said top block by means of said press means that is applied thereto in selected amounts which may be increased successively with sequential reciprocations of said roll assembly until recip-rocation occurs with said top block positioned in the closest proximity to said base block that is permitted by said stop blocks.  The apparatus of the in-vention has utility in the formation of complex-shaped objects or articles from metal stock which is not highly ductile or malleable.
