Abstract: A ribbon speaker system comprising a three-element tweeter, midrange and woofer acoustical transducer unit is disclosed. The tweeter transducer consists of a single, elongated, corrugated aluminum ribbon positioned vertically and connected to the top and bottom of a rigid, elongated frame. Electrical connections are provided at the top and bottom to permit current flow along the length of the ribbon. The aluminum ribbon is located between sets of magnets which are designed to provide a shaped magnetic field that provides magnetic centering of the ribbon. Additional electromagnetic containment for the transducer ribbon is provided by electrical current passing through the ribbon which current returns to its source by means of flat ribbon conductors located on the surfaces of the magnet sets. 
<??>The midrange transducer consists of a single elongated corrugated aluminum ribbon positioned vertically and connected to an elongated frame similar to the tweeter transducer. However, unlike the tweeter transducer, the edges of the midrange ribbon are acoustically sealed to the frame by foam strips. In addition, desired dynamic properties of the ribbon are achieved by fabricating the aluminum ribbon with corrugations that extend at variable slant angles relative to the longitudinal axis of the ribbon. 
<??>The woofer acoustical transducer consists of an elongated, trapezoidal-shaped, corrugated aluminum ribbon that is supported on all sides and mounted vertically in a rigid, elongated frame. To provide a single electrical path through the ribbon it is divided by a series of horizontal cuts into a serpentine pattern. The ribbon is located directly in front of a rectangular array of ceramic magnets mounted on a steel backing sheet.

Title: Test plate assembly defining discrete regions on a microporous membrane with low boundary distortion

IPC: G01N33/48

Abstract: TEST PLATE ASSEMBLY DEFINING DISCRETE REGIONS ON    A MICROPOROUS MEMBRANE WITH LOW BOUNDARY DISTORTION                 ABSTRACT OF THE DISCLOSURE       A biochemical test plate assembly for use in multiple simultaneous contact tests arranged in a fixed array of discrete regions on a single microporous mem-brane sheet provides less distortion of the boundaries of these regions than do pre-existing assemblies.  Like its predecessors, the assembly contains two apertured plates; an apertured gasket sheet and a microporous membrane, both placed between the apertured plates; and a third plate for placement beneath the apertured plates, having a recess which serves as a reservoir for liquids passing through the membrane.  The improvement resides in the enclosure of the lower apertured plate by the upper apertured plate and the base plate, thereby seal-ing the lower apertured plate and the microporous mem-brane off entirely from the atmosphere.  This eliminates evaporation of moisture from the edges of the membrane, and any lateral diffusion of biochemical species which might occur as a result due to capillary attraction.

Abstract: ABSTRACT: "Camera for recording television, photographic or cinema-tographic images, including an automatic focus-setting device".   A camera for recording television, photographic or cinematographic images includes  an automatic focus-setting device. Information for this device is obtained with the aid of two optical paths having different path lengths present in an optical lens system placed in front of an opto-electronic sensor in the form of a charge transfer device comprising a pick-up member, a storage member and a shift register member. After a signal compar-ison of signals obtained during focus information recording periods the focus is set until an optimum signal correlation is the result. To realize a camera with both an undisturbed scene recording as an automatic focusing while using one and the same sensor for this purpose it operates consecut-ively during a television field period (TV) with a scene recording period (TVS), a scene information transfer period (TFV) for the transfer of information between the pick-up member and the storage member, at least one focus inform-ation recording period  (TAS or TBS, respectively), the first and second optical paths being present in the op-tical lens system and a focus information transfer period (TFA or TFB, respectively) for the transfer of information between the pick-up member and the storage member. Another sequence may be:          TVS, TFV, TAS, TFA, TBS and TFB.            Figure 2.

Abstract: "MODULAR FURNITURE"                 ABSTRACT OF THE DISCLOSURE      The present invention is related to an innovative modular office, reception, and industry furniture, structured on the basis of multiple sections which are assembled using slots and ridges, to integrate a modular furniture which consists of four working areas, with filing cabinets, bookshelves and individual lateral tables or to integrate a whole piece comprising two individual modules which include a desk, a filing cabinet and a table which is shared by both modules.       Due to the innovative structure, form, assembly, and functional features of the individual sections, the modular office furniture now provided and the modular furniture with a shared table for the two individual modules are considered notable developments in this field.                 BACKGROUND TO THE INVENTION In the field of industrial activity of the manufacture of office furniture, the typical desk is well known and these are manufactured in a great variety of designs basically consisting of a horizontal desktop, held by several legs, generally four, with or without drawers in some designs, with a horizontal work area including integrated or detachable shelves.       On the other hand, recently, modular office furniture is being designed, which commonly comprises one or more working tables, separated by vertical dividers which can be adjusted and removed.  These modules are built with the purpose of occupying the least possible space to be used by the greatest number of persons possible.  In many offices, the area allocated for the working furniture of the personnel is generally restricted, thus it becomes necessary to use small desks or small modules, individually adjustable, to accommodate the greatest number of persons possible. The known modules have solved part of that problem, but have the disadvantage of being uncomfortable or very expensive, since in its manufacture not only wood is used, but also other materials such as steel, aluminum and even plastics.

Abstract: "OIL WELL SUCKER ROD COUPLING ASSEMBLY' ABSTRACT OF THE DISCLOSURE         A sucker rod coupling assembly is provided for connecting a pair of sucker rods and centralizing the rods in a tubing string.  The coupling assembly finds particular application in connection with a rotating rod string driving an oil well downhole screw pump.   The coupling assembly comprises a cylindrical solid steel shaft having externally threaded pin ends. A tubular sleeve or layer formed of non-metallic soft resilient abrasion-resistant material, such as polyurethane, is bonded to the surface of the shaft and extends its full length between the pin ends.   A pair of internally threaded steel sucker rod box couplings is also provided.  The box couplings are provided to interconnect the shaft with the pair of sucker rods.   The shaft end face of each box coupling has a ring of soft resilient abrasion-resistant material bonded thereto.   A tubular externally fluted centralizer, formed of the same material, fits loosely around the shaft.   The centralizer has a snug fit in the tubing and is frictionally gripped so as to be stationary in use.   One or more notches extend transversely across the upper end face of the centralzer, to permit fluid flow therethrough so that the centralizer does not seal against the coupling above it.  The polyurethane layers on the shaft and coupling end faces protect the steel  parts of the coupling assembly against severe abrasion wear from sand particles proceeding through the annular clearance between the centrailzer and the shaft. By providing a non-rotating non-metallic centralizer at the locus of the large diameter box ends, wear of the tubing wall is substantially reduced.
