Granted: 1982-09-14
Abstract: ABSTRACT      A photographic system is particularly adapted for use in a check security system and offers novel features and advantages for such systems.    Such system includes a film cassette and film cassette holder.  The film cassette may be molded from plastic parts and can be adapted for assembly and operation without fasteners.  The film cassette forms a light tight enclosure with a first opening to admit an image and expose the film within the enclosure and a second opening to permit operation of a film take-up within the cassette.  The system includes shutter means adjacent the image-admitting opening of the cassette that can be operated by an actuator carried by the cassette holder.  A second actuator carried by the cassette holder can engage and operate the film take-up of the cassette.  The cassette can movably carry elements of the system shutter means and provide reliable film take-up and film guidance within the cassette enclosure.  The system is capable of being operated in a lighted environment and permits the controlled exposure of film carried within the cassette to a plurality of sequential and separate images focused at the image-admitting opening of the cassette.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a unique tool chest which combines the convenience of pegboard display with the mobility and security of a locking tool chest. A slidably disposed pegboard is contained within the tool chest and mounted on rails.  A winch with a cable is located on the exterior of the tool chest and works in conjunction with the pegboard so that when the top lid of the tool chest is opened and the winch is cranked, the peg-board will extend upwardly out of the top of the tool chest and lock in the desired position.  Thus easy access is provided to the tools hung upon pegs on either side of the pegboard.  Doors located on the front and the rear of the tool chest allow access from either side.  The entire tool chest sits upon a foundation piece provided with casters for easy mobility.

Abstract: IMPROVED ADJUSTING TORQUE WRENCH          Abstract of the Disclosure An improved adjusting torque wrench includes an ad-justing screw that is utilized for the purpose of changing the torque setting of the wrench.  The screw has a radial flange thereon having a plurality of circumferentially spaced notches in the outer periphery of the flange.  The adjusting screw is fixed to the grip member and rotatable therewith relative to an adjusting nut that is fixed in the lever arm of the wrench.  A detent that is movable into and out of the recesses in the adjusting screw is slidably carried by the lever arm so that when engaged in the reces-ses, the detent prevents relative rotation between the grip member and the lever arm, and thus prevents adjustment of the torque.  Also, the detent extends exteriorly of the gripping member so that it can be grasped by the operator of the wrench and moved out of the recesses so that the wrench can be easily adjusted to a new torque setting.

Abstract: MICRO-VECTOR PROCESSOR            ABSTRACT OF THE DISCLOSURE       A micro-vector processor has an input and output section, a supervisor section, a vector unit section, and a memory common to all of the sections and accessible by each.          The signals to be processed are supplied by the input section in digital form to the data memory unit.  The supervisor section is programmable and acts as the overall micro vector processor control processor,  The supervisor unit sets up, starts, and monitors the actual signal processor, the vector unit.  The supervisor orders the vector unit to go to a reserve location in the data memory unit where it finds the beginning address of a command-parameter list (CPL) previously loaded into data memory by the supervisor unit, containing the name of, and the parameters for, the utility algorithm which the vector unit is to execute.  The algorithms that the vector unit performs are contained in the form of micro instructions in a read-only memory (ROM) which controls the operation of the vector unit.          The vector unit sends results to the data memory unit and informs the supervisor that its task has been completed.  The results are sent from the data memory to the output section.       The vector unit, once started by the supervisor unit, is completely autonomous from the supervisor unit.  The supervisor unit may control a plurality of vector units by simply invoking each one which then runs autonomously.  Also, the entire micro-vector processor may be connected in an array with other micro-vector processors to form a distributed signal processing system.

Abstract: ABSTRACT: "A device for differential image determination."         The invention relates to real-time (X-ray image) signal processing with which it is necessary to have only one memory with a capacity for one X-ray image. Via an X-ray image intensifier-TV chain consecutive X-ray images are sequentially fed in digital form to a recursive filter. The memory is employed in the recursive filter as a "delay element", as result of which a. noise integration and b. differential image determination between consecutive images take place.

Abstract: POLARIZATION ROTATABLE ANTENNA FEED          ABSTRACT    A  wave guide of an antenna feed assembly has a wave polarization rotary   section  comprising  a  plurality  of   closely   spaced conductive pins extending across the diameter of the wave  guide.          A  first  group of such pins adjacent the output end of the  wave guide to an amplifier are stationary while a second plurality  of pins  are  rotatable  about the axis of the feed  in  progressive steps  through  each pin to 45°  positions selectively to one  or the  other  side of the plane formed by the  stationary  pins  to rotate one or the other of the 90°  polarized waves 45°  into the plane  of the stationary pins and thence to  the  amplifier.  The movable  pins are received in a collar rotated by a  conventional motor,  the pins being located in slots of varying lengths in the collar  so that each rotatable pin lies at the same angle to both of  its  adjacent pins.   A ridge plate is employed in  the  wave guide  to coaxial connector transition to provide a ridge  loaded wave guide transition section;  the ridge plate extending from  a wall  of  the circular wave guide to the center conductor of  the coaxial  connector with the point of contact being  located  such with  respect  for  the end wall of the wave guide to  provide  a resonant  circuit  at the  frequencies  under  consideration.   A matching  boss located at the contact of the ridge plate and  the center  conductor  is employed to add capacitance and  assist  in providing broad band tuning.

Abstract: Docket M-410 Abstract of the Disclosure A high quality, variable font, matrix printer employs a precise carriage position control system that precisely determines the position of the carriage at discrete positions in combination with a variable time delay in the matrix element firing circuit to permit each printed matrix element to be positioned at one of the various carriage positions, or between discrete carriage positions, thereby permitting essentially continuous horizontal lines and high quality characters of various fonts and sizes to be printed. In such a system, the positions of the elements forming the particular characters to be printed are defined by stored information representative of carriage position and time delay.  Essentially continuous vertical lines are generated by precisely controlling the paper feed to permit matrix element overlap, and characters larger than the printing matrix may be generated utilizing multiple printing passes with an appropriate paper advance.
