Abstract: A storage container for holding a commercially packaged compact video disk. The container is adapted for molding in a unitary structure of a thermoplastic material. The container cover is provided with opposed tabs for engaging the cover flap of the commercial package such that the same is opened when the container is opened. When molded of a substantially transparent thermoplastic material, the container allows display of the commercial package graphics.

Abstract: A multi-purpose tool for opening a variety of pail or bucket types of containers and having a handle portion from which a claw-type opener extends from one end and optionally a plurality of projections adapted for opening particular types of containers extend from the opposite end.

Abstract: A metal blade trowel having a handle formed of a thermoplastic material directly attached by injection molding through an elongate aperture extending along the longitudinal centerline of the blade.

Abstract: An insulative housing has a first recess provided with a threaded metal insert adapted to engage a threaded antenna mount on a vehicle. A second relatively smaller recess through which an antenna whip extends has a compression spring which, when the antenna is installed on the vehicle, urges the contact at the lower end of the whip into secure electrical contact with the contact on the mount and also operates to compress a weather seal about the whip at the upper end of the recess.

Abstract: A low profile mobile antenna mounting of a simplified construction having a stamped sheet metal mounting bracket adapted for use with multiple size openings in the vehicle body.

Abstract: A package for blasting agents including an outer bag of a first diameter formed of a multilayer rupturable paper material and an inner waterproof bag of a second diameter larger than the diameter of the outer bag such that, upon being dropped into a blast hole, the outer bag ruptures allowing the inner bag to expand to the full cross section of the hole without tamping while maintaining the blasting agent in a waterproof condition.

Abstract: A system for sensing a leak of ammonia refrigerant into a refrigerated environment and for automatically purging the refrigeration equipment within the environment of refrigerant.

Abstract: A plurality of circular grout striking projections each having a radius different than the rest are arranged about the periphery of a central circular disc such that no projection interferes with the use of any adjacent projection in striking grout between pieces of tile.

Abstract: A method and apparatus for defining a plurality of subcategories of the information content of the input to a reproduction system and generating a set of signals corresponding to each such subcategory for the system output and an idealized output. The sets of signals are analyzed to derive a third set of signals which are used to improve a selected aspect or characteristic of rendition fidelity of the reproduction system output. While the invention is described in the context of video systems the principles disclosed are equally applicable to photography, optical scanners and audio systems as well as other multi-channel reproducing systems.

Abstract: An apparatus for automatically de-packaging products and separating the product from its package wihtout contamination of the product and having an improved, continuous feed agitating hopper, a product-orienting feed chute and being adaptable for operation without tumbling the product and package together.

Abstract: A system for monitoring energy use by each of a plurality of tenants or other users of energy provided by a common heating/cooling plant and for allocating the energy expense for a building among such users on a pro-rata basis.

Abstract: A laminated air permeable container cap lining and sealing material comprising layers of pulp, aluminum foil, paper, wax, paper and air permeable heat sealing material.

Abstract: A method and apparatus useful in both the recording and playback of audio recordings for correcting the effects of acoustic distortion introduced by the room in which the recording is made and/or played. An acoustic test impulse is generated and the response observed to establish the acoustic properties of the room. The response is sampled and used to generate an equalizing function which may be stored and convoluted with the audio signals being recorded or played to substantially eliminate the distortion. In an alternative embodiment the corrected signals may be further convoluted with a function representing the acoustic properties of a different room environment.

Abstract: A spatula type hand implement having integrally formed handle and blade portions and a compound curved reinforcing blister molded therein along the longitudinal axis across the transition between the handle and blade portions.

Abstract: A sinker-anchor for fishing in moving water and having a weighted body with an open tube extending through and outwardly from the body along the centerline, such that a fishing line is free to pass therethrough. A plurality of anchor prongs extend outwardly of the body to engage the bottom and retain the sinker in a desired location.

Abstract: Apparatus for polishing a workpiece wherein an oversize resilient elastomeric polishing die has injector ports through which a viscous or elastic polishing medium is injected. The workpiece is mounted in vertical working alignment with respect to the polishing die. The die and workpiece are moved relative to one another in a horizontal oscillatory rotary motion as they are brought together in the vertical direction such that the workpiece surfaces are polished. The workpiece is heated to enhance the polishing efficiency.

Abstract: Method and apparatus for developing and recording information relating to the color present in a scene under certain illumination conditions. The developed information may be analyzed and compared against certain standards and adjustments made either before or after the scene is recorded on color film to maximize fidelity of the color reproduction during the processing of negatives and prints from said film. An optimized exposure correction is provided for any given set of specific primary spectra of each film layer sensitivity and print dye component for a preferred set of test colors.

Abstract: An abrading apparatus for shaping electric discharge machining electrodes wherein an abrading die is provided with a thin coating of electrically conductive material. The conductive coating and the electrode workpiece are electrically coupled to a switching means to provide a zero reference output signal when the die and workpiece are first driven into contact with one another.
