Abstract: ABSTRACT           A tamper evident closure and package having a container (10), a resealable, substantially rigid closure (12) for closing, opening and reclosing the container (10), color changing means (32a in Figures 1-6) which effect a color change upon stretching, and coacting mechanical means (24, 36, 44 and 46 in Figures 1-6) for uncapping and recapping the closure 10 and for stretching the color changing means (32a) which clearly and unequiv-ocally indicate the condition of the package, e.g., open or closed.     Where legends, or other well defined indicia, indicating opening is desired, the color changes can be localized in the skirt by providing thin sections (32a) which stretch preferentially and adjacent thicker sections (38) which remain substantially unstretched.  The thin sections (32a) for example can be a legend, or alterna-tively the thick sections (38) can be the legend while the thin sections (32a) provide a suitable background.     The color changes employed by the invention can be accomplished by such phenomena as stress whitening inherent in various plastic materials.  Alternatively, the color changes can be accomplished by mechanisms such as the use of encapsulated staining or coloring agents incorporated in a suitable matrix.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for automatically mounting chip type circuit elements on printed circuit boards is constructed in a manner to mount a feed wheel for carrying out the delivery of a chip tape on a lower frame.  A lever is mounted with respect to the feed wheel through a one-way clutch, so as to allow the lever to be pressed by a cam provided on a reciprocating upper frame which supports a mounting head.  The feed wheel is thus rotated in the actuating direction of the one-way clutch to intermittently feed the chip tape and permit another chip type circuit element to be disposed at a chip type circuit element removing position, each time when the mounting head is returned to its original position.

Abstract: To produce a panel of variable thickness, a stratified assembly of a layer of fibers containing a non-polymerized binder and at least one cover sheet is placed between the mold and mold-backing of a molding press. The stratified assembly is caused to conform to the interior surface of the mold or mold-backing by forcing the cover sheet against the mold or mold-backing interior. Hot air is blown into the fiber layer from the mold surface opposite the cover sheet, into at least the region that will correspond to the area of greater thickness. The direction of the heated air is reversed after a period of time, the blowing of the air being maintained and adjusted in order to secure polymerization of the binder. At the same time, the portions of the panel corresponding to areas of lesser thickness, generally the edges of an acoustical panel, are cured (the binder polymerized) by contact heating means. To effect cross-over blowing, both the mold and mold-backing are provided with ports through which heated air may be blown or passed.

Abstract: Abstract of the Disclosure A transportable building module including a load-bearing support frame which includes a pair of spaced apart portal frames, a floor frame and a roof frame The floor frame includes two elongated open web trusses having tubular floor purlins secured in spaced relationship therebetween.  Reinforcing floor elements are secured to the upper surfaces of the open web trusses and the floor purlins.  Reinforcing mesh is draped across the area of the frame to receive a reinforced concrete slab floor with the mesh being received around the upstanding reinforcing elements. Clip elements may be received around peripheral reinforcing elements, if needed for peripheral reinforcement, and a concrete slab is produced in situ about the floor frame, encapsulating the reinforcing elements, which concrete floor will undergo transit of the building module without damage.  The roof frame includes longitudinal tubular beams with roof purlins secured therebetween, the purlins having a predetermined slope across the width of the module, such that a roof secured thereto will have a like slope.  Non-load bearing exterior and interior wall structures are secured to the load bearing support frame system which conceal the structural elements of the frame.  Preferably, the exterior wall elements are glass reinforced concrete panels which are secured around the exterior of the frame, while the interior wall structures are rigidly secured at a lower end to the concrete floor and flexibly secured at an upper end to a portion of the structure.  Interior wall panels such as gypsum board may be secured to the wall structures and are preferably reinforced across the face of same and joints therebetween, preferably with either a fabric adhesively secured thereto or a flexible polymeric film produced in situ thereacross. Each individual module is virtually complete when it leaves the factory and has structural integrity, such that connections between adjacent modules generally do not require structural connections other than necessary to ensure coplanarity of adjacent surfaces.

Abstract: ABSTRACT        A method for installing an automatic guided vehicle system guide path in the form of an inductive loop disposed beneath the floor of a factory or other facilities includes the steps of establishing a desired floor layout to meet the needs of the facility wherein the system is to be installed, cutting a trough or slot in the floor following the layout with a saw, placing the signal wires into the slot, installing a mechanical seal in the floor slot flush with the floor surface, setting the mechanical seal to a final depth, and applying a primer and final seal over the slots including the mechanical seal.  The signal wires are thus retained "free floating" within the slot rather than being solidly embedded in the floor, and are relatively easily accessible by removing the mechanical seal and final seal for access for repair and maintenance.

Abstract: ABSTRACT OF THE DISCLOSURE    In an image pickup apparatus or television camera tube in which a signal corresponding to a target current of the television camera tube is supplied to its beam current control electrode to thereby control the beam quantity to become corresponding to the variation of the incident light amount thereon, the present invention is to provide an automatic beam current control system for a television camera in which the signal corresponding to the target current is supplied through a line adder circuit to the beam current control electrode.    The line adder circuit may use, for example, a one horizontal period delay line.  Since the control signal supplied to the beam current control electrode is an added value or an average value of the target currents obtained over two scanning periods, the stable control signal is always supplied to the beam current control electrode of the television camera tube so that the image picked up signal of high definition without a line crawl componet can be obtained.

Abstract: ABSTRACT           The density of the energy that is conducted within a fiber-optic waveguide is increased by means of an energy coupler at the input end of the optical fiber.  This energy coupler comprises a fused or ground lens at the input end of a silica-based fiber.  A second lens, preferably a plano-convex lens, focusses a large collimated laser beam to a point source.  The lens at the end of the fiber is located at a distance greater than the focal length of the second lens, so as to receive light from the point source and couple it into the fiber.
