The frame structure carries external sealing gaskets for the peripheries of said panes and arranged so that said panes are put in place from the interior face of the structure. Internally of said panes, clamping means are disposed to urge said panes into sealing engagement with the gaskets with an adjustable force. The external sealing gaskets cover those parts of the frame structure that project externally of said panes.

Abstract: A method for the production, without thermal treatment, of an anti-reflection coating on surfaces of optical elements of transparent, thermally sensitive material such as organic polymeric plastic material which comprises coating the surface with a layer of silicon oxide by vaporizing said silicon oxide by applying the energy of an electron beam thereto under vacuum in such manner that the vaporized molecules are ionized by said beam and are deposited on said elements in ionized condition. A multi-layer coating may then be applied by depositing with an increasing rate on said coating a layer of a substance of higher refractive index than that of said plastic material while continuing the deposition of the silicon oxide, and then depositing thereon a final layer of anti-reflection material such as silicon oxide. The substance of higher refractive index may an oxide of cerium, tantalum, titanium or zirconium.

Abstract: A device for the remote control of motions and operations, especially on microsurgical equipment, comprises a multiple switch assembly in which the operation of the selected switches is controlled by movement of a control member. Operation of the switches closes or opens electrical circuits which include servo-mechanisms for moving the equipment. The switches are mounted in a housing and the control member comprises a plate having a stud extending through an aperture in the cover of the housing. Selective operation of the switches is brought about by transverse movement of the plate and stud in various directions.

Abstract: The invention contemplates an improved method of electronic-image analysis within a field of raster-scanned subject matter in which each scanning line lying within the boundaries of an object to be evaluated supplies by means of a discriminator a binary signal corresponding to the line length between object-boundary intercepts for the particular line. The improvement involves production of a localized search signal synchronized with raster scanning such that the search signal is effectively located within at least part of the scan-line coverage of the object. The search signal is used to control for each scan line the delay time of the binary signal of the same scan line, said delayed binary signal starting an output signal, the delay time of said binary signal being so controlled that it lies between a scan line period T.sub.1 and a minimum time T.sub.2 and depends upon the time interval between the start of said binary signal and of said output signal.

Abstract: The invention contemplates a method of microscopic analysis of biological, metallurgical or other specimens, wherein an image copy of a comparison or reference object is used to produce a comparison image in the image plane of the microscope eyepiece. A direct side-by-side comparison can then be made for the unknown or unclassified specimen, against the image copy, which may be two adjacent image copies, displayed alongside the unknown, to enable a judgment as to the resemblance between the unknown and one or the other of the two image copies.

Abstract: In a continuous casting plant having a ladle shop and a separate casting shop, each served by a separate traveling crane, means for supporting one or more ladles are located in the ladle shop and means for supporting one or more molds are located in the casting shop. A tundish is positioned to extend across the space between the two shops with one end of the tundish located below a ladle to receive molten metal therefrom, and with the other end located above the mold to discharge molten metal into the mold. One or more tundishes are mounted on pivoted carriers on which the tundishes may be moved selectively from casting position to a position in the casting shop where they may be removed from the carriers for repair and reconditioning, and on which tundishes may be moved to preheating and prefill positions.

Abstract: A positioner for a fluid-operated actuator has a fluid control valve displaced by a controlling force applied to a force-balance lever engaging one end of a biasing spring, the other end of which engages feedback means including an element displaceable by actuator movement. The valve lies between the biasing means and said feedback means element. Adjustment means are provided for the spring and for the feedback means to set the actuator zero position and movement range. Fluid conduits from the valve comprise open channels in a unitary member containing the valve and with a wall of a housing form closed section passages to porting in said wall opening directly into the actuator porting.

Abstract: In an offset lithographic printing machine a recess is provided in the offset blanket in a position such that when the recess is at the nip between the blanket cylinder and the printing plate cylinder the recess is in registry with a part of the non-printing area of the printing plate. The amount of water on that part of the non-printing area is then determined as, for example, a function of the amount of radiation reflected by that part.

Abstract: The invention contemplates improvement in the interpretability of heat-detection data, resulting from scanning a field. One or more heat-detecting devices are caused to scan the field and to create light modulation, superposed on a monitoring display of the field, the monitoring display being the product of observing the field in a band (e.g. visible light) other than that of the scanned heat response. The result is to superpose on the monitoring display brightened light modulations in accordance with heat sources encountered in the course of heat scanning the same field.

Abstract: Samples of fine dusts in air or gases are collected for analysis and measurement by atomic absorption or atomic fluorescence by conducting the air or gases across a surface of a sample container and causing the dust to be deposited electrostatically on the said surface. The sample container is then heated to a temperature sufficient to vaporize the particles of dust, and the vaporized particles are then brought into the beam path of an atomic absorption or atomic fluorescence spectrometer.

Abstract: A lubrication and sealing system for the cylinder head of an internal combustion engine having a sleeve valve mounted for rotation therein, said sleeve valve having intake slots therethrough which register periodically, as the valve rotates, with air intake ports in the cylinder to permit air to enter the cylinder. The sleeve valve is provided with one or more helically shaped sealing rings carried in the wall of the valve facing the wall of the cylinder, which said rings, as the valve rotates, sweep the wall of the cylinder to circulate lubricant oil within the clearance space between the valve and the cylinder to thereby lubricate and seal the clearance space. The circulation of lubricant also has a beneficial cooling effect.

Abstract: In a continuous casting process in which a partially solidified strand of rectangular cross section is formed continuously in a water cooled mold and comprises upper and lower curved surfaces of different radii, and in which the said strand is curved and follows a curved path through a secondary cooling zone, the curved strand is straightened by applying cooling water to the curved surface of the strand which is of greater radius at an intensity sufficient to reduce the surface temperature thereof below the surface temperature of the surface of lesser radius to produce a temperature differential between said surfaces sufficient to straighten the strand.

Abstract: A planar structural assembly has a series of cells formed by elongate structural members, the cells each receiving a pane or panel. To provide a weather-seal, closed loops of resilient sealing strips extend around the exterior edge of each pane or panel and are mounted on auxiliary members secured to the structural members. The auxiliary members clamp the sealing strips in compression against their panes or panels to ensure the seal there. The contiguous edges of the sealing strips of adjacent cells are locked in place and a seal formed between them by locking or zipper strips.

Abstract: In an apparatus for making organic fertilizer from waste organic materials by aerobic fermentation, the interior of an inclined slowly rotating digester cylinder is provided with a series of knives which gradually cut and shred the softer components of the raw material and a series of heavy chains located downstream from said knives, which said chains have overlapping loops which crush and grind hard and brittle components of the raw material, all while the material is in process of aerobic fermentation. Materials which resist the comminuting action of both the knives and chains are discharged with the digested organic materials and are then separated therefrom. The apparatus is capable of accepting and treating municipal garbage and refuse without prior separation of unwanted material, and without preliminary grinding of the material prior to its introduction into the digester.
