Abstract: The present invention is directed to a three way valve having particular utility as an air control valve and providing an enhanced duty cycle. A characterizing feature of the valve resides in the construction and arrangement whereby the valve plunger is, in all conditions of operation, slidably guided for precise axial movement in a bore whereby any tendency of the plunger to tilt or cant, with accompanying damage or scarring of internal elements of the valve structure, is positively prevented.

Abstract: An envelope opener device is provided characterized in that the envelope, which is automatically fed, is slit through only a single face of the envelope whereby no portion of the envelope is severed entirely, thus minimizing the possibility of loss of the contents. A further characterizing feature resides in a unique device for adjusting the cutting depth to achieve a precisely desired cutting effect, the depth adjustment means being actuatable for the slitting of envelopes of thinner stock, such as air mail envelopes. The device is resistant to feeding an envelope which is so disposed that the envelope contents are in registry with the cutting mechanism, thereby minimizing the possability of damaging the contents.

Abstract: The present invention is directed to an improved bidirectional cassette transport wherein the various operating modes can be achieved through the use of a single lever. The device is characterized in the provision of a novel coupling arrangement between the control lever and the cassette drive whereby the cassette is virtually jam-proof, is protected against damage, and a constant tension in the tape is achieved. The device is particularly suited for use as a leasable player cassette of the type frequently employed in museums for supplying explanatory background and like information in conjunction with the exhibits. The suitability of the device for such use derives from the ease with which the same may be operated, the foolproofness of its operation and the facile manner in which portions of the auditory materials may be repeated.

Abstract: The present invention relates to improvements in treatment rolls for the corona discharge treatment of polymeric films whereby the same are rendered receptive to printing inks and the like. More particularly, the invention is directed to a treatment roll and method for use as an electrode in a corona discharge device, the roll being comprised of a metal substrate having a porous ceramic coating, the interstices in said coating being filled with silicone polymer, the roll evincing a high resistance to wear and electrical breakdown, whereby higher volumes of material may be processed.

Abstract: The present invention is directed to an improved method and apparatus for effecting spot welds between superimposed sheets of galvanized metal. In accordance with the method, one of the electrodes is comprised of a consumable tip component, preferably a steel ball, whereby predictable and repeatable welding conditions are effected at each welding cycle. The invention is further directed to a method of effecting spot welds between galvanized sheets which includes the step of interposing between a conductive carrier electrode and the metal surface a consumable metallic increment having reduced contact area adapted to engage the galvanized sheet, the consumable component being compatible with the ferrous subtrate beneath the galvanized layer.

Abstract: The present invention relates to a high efficiency non-tracking solar collector device of the type in which a reflector, lens or like concentrating apparatus concentrates received energy along a path, locus or band, the location of which varies within a range during the course of the solar collecting period of the day responsive to the inclination of the sun relative to the reflector. The device is characterized by the provision of a collector assembly which includes an energy absorptive receptor surface spaced from the reflector in accordance with the focal length thereof, the receptor surface defining a boundary of a plurality of parallel paths or conduits within which heat transfer fluid is caused to flow.

Abstract: The invention relates to a bearing assembly adapted to be connected to a damper blade, and particularly a damper blade intended to be disposed within the duct of an air conduit used in a heating or cooling system. The assembly is characterized in that the bearing pin is supplied in a first position, from which it may be partially retracted, and after installation may be shifted to an extended position from which, if necessary, it may likewise be retracted, making it particularly suitable for installations wherein the duct interior is provided with an insulating lining.

Abstract: The present invention is directed to a dead shaft bearing device for an auger type conveyor. The device is characterized in that the bearing components are readily replaceable without the necessity for disassembling the conveyor, and provide a leakproof assembly barring ingress of pulverulent material to the bearing surfaces and escape of pulverulent materials through the wall of the conveyor trough.

Abstract: The present invention is directed to a diagnostic instrument for measuring the deformation resistance of tissue, and particularly the articular surface of the patella. The instrument comprises a cannula adapted to be inserted into end abutting contact with the surface to be measured and a carrier member insertible into the cannula and carrying a pressure sensing device.

Abstract: The present invention relates to a photographic print and process of making the same wherein the print presents highlights by a build-up of high reflective, e.g. specularly reflective, metal in the highlighted areas which would otherwise print as blank or very light-toned areas of exposed paper or film. The gradient areas are preferably defined by spaced, specularly reflective areas optionally interspersed with conventional deposit of particulate silver. The method of fabricating such article includes an initially conventional development step, followed by a second development step wherein the silver halide areas remaining after the first development step are converted into increments of specularly reflective silver. An etching step may be interposed between the conventional development step and the development step leading to the creation of specular areas.

Abstract: The present invention relates to a recloseable multi-seal package for food or the like characterized in that a triple seal of the contents is effected, and further characterized in that, upon removal of a sealing film or membrane, identifying indicia printed on a central portion of the film remain on a replaceable cover member.

Abstract: The present invention is directed to a multiple compartment, multiple seal container particularly adapted for packaging plural portions of foods or the like. The device comprises a first container formed of polymeric material or the like and a second container adapted to nest within the first container. A lid member having a skirt extending into the second container provides a seal therefor. The lid and first container, and preferably also the second container, include flange portions disposed in coplanar alignment. A membrane, such as a cellophane membrane, is disposed in registry with the first container and is sealed to the lid and to the first container, and optionally also to the second container, along continuous seal lines, to provide a composite package including discrete compartments having multiple seals.

Abstract: The present invention is directed to a window of the tilt and turn type which may selectively be positioned in a locked condition wherein the window member is in coplanar alignment with the frame; in a vent position whereat the window is tiltable about a horizontal axis adjacent the lower edge thereof; and a casement position whereat the window may be pivoted about a vertical axis, as for cleaning. The device is characterized in that the operating mechanism controlling the various conditions of operation of the window is provided with safety interlock means whereby the window may not be dislodged from its normal operating conditions by inadvertent or improper actuation of the operating handle.

Abstract: This invention relates to a connector device, and more particularly to an electrical connector plug, jack, tapping device or receptacle which provides a direct current path between an input and an output terminal, which path is automatically opened responsive to the insertion of a fuse, after which the sole conductive path between the terminals extends through the fuse.

Abstract: The present invention is directed to an improved method and apparatus for effecting spot welds between superimposed sheets of galvanized metal.
