Abstract: DATA STORAGE AND RETREIVAL SYSTEM                ABSTRACT OF THE DISCLOSURE        Preferably, a linear array of light sensing elements is positioned opposite light projected images of alpha-numeric or pictorial data recorded on the frame of a microfiche card or the like.  Each alpha-numeric character or pictorial pattern segment is dividable into individual rows and columns of image-forming spots which together form a particular alphabet or numeral char-acter or pictorial pattern segment.  The sensing elements and the image spots projected thereon are related in size such that an integral number of light sensing elements are required in both X and Y axis directions to intercept a single image spot.  One of the microfiche card or light sensing elements are movable relative to the other so that the various image spots projected therefrom are scanned during a given scanning cycle.  The outputs of the sensing elements are sampled at a frequency such that the sampled light sensing element outputs over a given scanning cycle repre-sents the outputs of a hypothetical multiplicity of groups of light sensing elements of said size, together encompassing the entire image field involved, with each group intercepting one image spot.  The sampled outputs of the light sensing elements are fed to threshold detector means, which detect only signals repre-senting signals above or below a given threshold level.  The threshold detected signals are initially stored as markers in a storage unit having respective groups of storage points respec-tively corresponding in number and position to the various groups of light sensing elements for said hypothetical multiplicity of groups of sensing elements.  The markers in said groups of storage points are respectively "OR" gated, and the gated signals are stored as markers in corresponding storage points in a second storage unit.

Abstract: OVERLOAD PROTECTION APPARATUS FOR HYDRAULIC MULTI-FUNCTION        EQUIPMENT                    Abstract of Disclosure This invention relates to an overload protection apparatus for hydraulic multi-function equipment. It is applicable to equipment sharing a common pressure and return line and in which functional operation of the equipment is interrelated such as to expose certain elements to overpressure conditions. The system includes an overload or overstress valve having a manifold to which the power lines of all of the actuators, except the principal actuator which responds to an overstress condition, are connected. These connections are directed through check valves so that fluid within the lines will be directed only to the overstress valve. A pilot valve connected to the power side of the principal cylinder controls a pressure actuated control valve in the manifold to control and open a passage to the reservoir. Thus, an overpressure condition representing an overstress to the equipment in the principal actuator will operate the pilot valve to unload the pressure lines of the associated actua-tors, thereby preventing their continued operation so long as the overstressed condition continues. This may be relieved by the operator reversing the operation of the motor causing the overstress condition.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to an amplitude equalizer for use in a signal transmission system.  Signal transmission systems require amplitude equalization in order to realize desired transmission characteristics.  Known equalizers produce more delay distortion the larger the equalizing quantity is.  Accordingly, high-speed transmission systems need more delay equalizers than level transmission systems.  This invention provides an amplitude equalizer consisting of a first and a second unit of amplitude equalizers disposed in series between a first input terminal and a first output terminal.  Each of the first and the second unit is supplied with a branching circuit, a synthesizing circuit, an amplifying or attenuating circuit, a circuit for delay correction and a phase shifting circuit whereby the delay distortion characteristics of the first and second unit are set to their complementary values to flatten the overall delay distortion of the equalizer.  Furthermore, the attenuation or amplification factor, the delay time and the phase shift are changeable to achieve variable amplitude and frequency characteristics.  The improved equalizer compensates both the amplitude and the own delay distortion of a signal in distinction to conventional equalizers, and is stable, versa-tile and easy to adjust.

Abstract: ABSTRACT       A low friction piston ring of split annular construction has a circumferentially extending recess formed at its upper outer portion to define an outer radial ledge which divides the outer axial surface of the ring into a recessed outer face and a reduced (as compared to the total outer axial surface) bearing surface.  The bearing surface preferably has a wear resistant coating thereon.  The outside diameter of the recessed outer face is less than the outside diameter of the bearing surface by an amount at least equal to the radial wear depth of the bearing surface.  A peripheral recess is also formed at the upper-inner portion of the ring to reduce or eliminate torsional twisting of the ring.  The ring provides a reduction in frictional resis-tance between the ring and the cylinder wall, good sealing against gas blow-by and enhanced engine performance and exhaust emissions control.

Abstract: ABSTRACT:               A recording system for recording signals on a magnetic tape comprises a recording apparatus and cas-settes, each containing a specific length of magnetic tape, which cassettes can be placed onto said apparatus, and has a timer by means of which time-preprogrammed automatic recordings can be made.              A detection device determines the maximum time available for recordings with a cassette placed on the recording apparatus and a comparator device compares an output signal of the detection devices with a reference quantity which is derived from the timer and which is a measure of the total time required for the preprogrammed automatic recording(s).  When this required time exceeds the maximum time available for recording with this cas-sette, an alarm signal is produced.  The cassette is pro-vided with marks which are detected by the detection device and which indicate the length of the magnetic tape con-tained in the cassette being used.
