Abstract: ABSTRACT OF THE DISCLOSURE            A grille for use as a sunscreen, decorative racing, vision barrier and the like is made up of a multiplicity of modular pieces, each of which is of uniform cross section along its length.  Each piece has walls terminating in spaced-apart parallel edges that define a base plane of the piece, and each piece is paired with another piece by bringing the edges of the two pieces together to produce a closed cell. An edge flange extends outwardly from a portion of the walls adjacent each edge of the piece, and a pair of closely-spaced, parallel slot flanges extend outwardly from a portion of the walls and define an outwardly open slot that is centered on a medial plane perpendicular to the base plane and parallel to the edges of the piece.  The slot is, moreover, spaced from the line of intersection between the base plane and the medial plane, which line may be considered the axis of the piece, distance substantially equal to one-half the perpendicular distance between the edge flanges.  The two pieces that form each cell are interconnected by reception of the edge flanges of that cell in the slots of adjacent cells, the flanges when placed together matching the slot in cross section and being urged apart into tight frictional engagement with the slot flanges by a nail-like element.

Abstract: ABSTRACT OF THE DISCLOSURE           Spherical antenna arrangements are disclosed utilizing annular slots in polar regions which are associated with resonant cavities having a TE01 mode or a TE11 mode of field distribution.  This field distribution within the cavity produces a cosine field distribution around the annular slot which serves via proper cavity excitation to produce nearly hermis-pherical isotropic radiation characteristics.  The resonant cavities may take on the form of a parallel-plate structure or a coaxial cylindrical structure.  Circular polarization and hemispherical coverage with uniform gain is characteristic of the antenna when the cavities contain probes placed ninety degrees apart in azimuth at the same radius from center and coupled to the quadrature phase related ports of a signal coupler.

Abstract: DOWNHOLE CABLE TENSION MEASURING APPARATUS            Abstract of the Invention Downhole cable tension measuring apparatus according to the invention is connected between a cable and well-logging apparatus suspended from the cable in a borehole.  A rod is placed between the cable and the well-logging apparatus so as to elongate elastically under the effect of cable tension.  A sleeve, fixed at one end of the rod, surrounds the rod.  A transformer, the primary of which is wound on the rod, the secondary of which is wound on the sleeve, detects the relative longitudinal displacement of the other end of the rod with respect to the sleeve. Two primary windings displaced on the rod are alter-nately excited to generate two signals in the secondary coil in order to correct temperature drifts of the circuits.  The rod and sleeve are made of the same metal so that each of them will elongate similarly as a function of temperature.  The apparatus is placed in a pressure-balanced oil-filled chamber.

Abstract: Abstract of the Disclosure A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame.  At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system.  Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%.  The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure.    Each individual modular press can be multi-opening and has the ability to open and close on command.  Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface.  The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets.  At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings.  The loading apparatus is pivotally mounted.  Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded.  The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.

Abstract: SURGE SUPPRESSION APPARATUS FOR    COMPRESSOR-DRIVEN SYSTEM ABSTRACT OF THE DISCLOSURE Surge in a compressor-driven system, such as a refrigeration system, is precluded by sensing an appropriate parameter, for example the gas flow at the compressor discharge outlet, and developing therefrom a feedback signal which dynamically varies the capacity of the compressor so that the discharge pressure versus discharge flow rate characteristic curve of the compressor always has a negative slope at the operating point, regardless of where that point is located on the curve.  By providing a negative slope at all operating conditions, the system is incapable of surge.  In order to satisfy variable load requirements, the compressor capacity is adjusted to vary the steady state operating point on the characteristic curve.

Abstract: Abstract of the Disclosure Aqueous metal ammine siliconate solutions are the reaction product of selected metals or metal derivatives, selected mono-organosilicon materials, certain alkaline nitrogen compounds having the formula R-NH2, and water.          Amorphous materials are formed when volatiles are removed from the siliconate solutions.  The metal components in the resulting amorphous material are not readily leached out by normal weathering, washing or the like.  The solutions are useful in a method for treating substrates, such as wood, textiles, thread, canvas, carpeting, paper and masonry, to confer antimicrobial properties.  The organosilicon component can be selected so that the treatments also confer either hydrophobic or hydrophilic properties to the substrates.  The components of the solutions can be selected to enhance their ability to form continuous films of amorphous materials when used in such treatments, making the solutions useful to provide antimicrobial coatings which may be either hydrophobic or hydrophilic.  Such amorphous coatings are useful for applications such as wood preservation, masonry water repellents, marine varnishes and as treating agents to give a desirable hand to fabrics.  Powdered amorphous materials can be used to produce antimicrobial ointments.  The solutions are useful as hardeners for water-reducible resins and emulsions, including latex paints.  The solutions can be adapted to include components which may be slowly leachable from the resulting amorphous materials which can thus serve as a controlled-release binder to provide prolonged antimicrobial protection not only to the treated surfaces but also to their immediate surroundings.
