Abstract: GATE HINGE CONSTRUCTION            ABSTRACT OF THE DISCLOSURE       Gates, such as farm gates, cattle gates and the like often sag after being installed for some considerable time, the ground below the gate changes level, or ground movement occurs all of which require repositioning of the gate relative to the hinge post so that the requisite clearance between the bottom of the gate and the ground is maintained.  Convention-ally the post hinge components are secured through apertures bored through the post and considerable time and effort is re-quired to alter or adjust the relative position of the hinge components with the post.  The present device is secured around the post and is firmly and securely anchored to the post when tightened.  It can easily be loosened and moved upwardly or downwardly relative to the post for adjustment purposes.  Each hinge assembly includes a front post engaging component to which the gate may be hingedly secured, and a rear tightening and clamping component with a chain extending around the post and the front post component and being adjustably tightened by the rear component to clamp the front component firmly and securely in position.  The hinge construction also facilitates initial installation of the hinges for the gate as no drilling of the hinge post is required.

Abstract: TITLE: DETERMINATION OF SYSTEM RESPONSE             ABSTRACT OF THE DISCLOSURE            Determination of the impulse response of a system such as a hydrophone is determined by generating a broad band reproducible test signal which after propagation is received and a replica of the broad band test signal is produced; either the received signal is compensated for fluctuations in propagation time of the test signal through the system and cross correlation of the compensated signal with the non-compensated signal is effected to derive the system response.  A secondary signal may be used with the broad band test signal whereby the Doppler shift of the secondary signal can be utilised to determine the required compensation.          Feed-back shift registers are disclosed for generating pseudo random noise for the test signal and the replica thereof.  The invention permits calibration of a hydrophone in circumstances in which noise is present and variation in path length of the propagated test signal occurs.

Abstract: ABSTRACT A full color high contrast image projection system with oil coupled dichroics is disclosed.  The preferred embodiment includes a unitary optical tank in which a prepolarizer and dichroic separators are mounted in fixed alignment relative to a main polarizing prism.  The prepolarizer acts on the incident light from a source to polarize the green light and reflect the S component out of the system.  The red and blue components are transmitted unchanged.  The main polarizer is mounted at a 90° twist relative to the prepolarizer so that it reflects the green light to a first light valve via a first dichroic separator.  The polarized red and blue components are transmitted to second and third light valves via a second dichroic separator.  The light valves modulate the polarization state of incident light before returning it to the second beamsplitter.  The second beamsplitter then recombines the individual beams into a single output beam.  This beam is projected by a telecentric projection lens to provide a full color high contrast image.

Abstract: OPTICAL KEYBOARD WITH COMMON   LIGHT TRANSMISSION MEMBERS                  Abstract A keyboard assembly is constructed of first light transmission members, second light transmission members, a key actuation assembly having a matrix of keybuttons, plural light source assembly and plural sensor assembly.          Each light source on assembly is exclusively and sequentially energized causing its light to be transmitted through the first light transmission member to be split up and deflected downwardly by the surfaces and then rightwardly by the surfaces to emanate through the surfaces to enter the surfaces of the second light transmission member.  Actuation of a keybutton causes its associated interrupter to assume a light blocking position between the first light transmission member and a second light transmission member.  Light passing through the second light transmission member to the sensor array indicates that none of the interrupters have blocked the light path.  This geometrical arrangement provides N key rollover detection with phantom key lockout and the light transmission members may be made of a single part or a single part for each row or column.  Such parts provide common light transmission paths.

Abstract: Abstract of the Disclosure Electron Optics of the Electron Beam Generating System of a Color Picture Tube By giving special shapes to the shielding parts in the electrodes of an electron beam generating system for the use with color picture tubes, there is obtained an improvement in the electron optics. In this way there is reduced in particular the twist error and a common sharpness or sharp focus point is obtained. At the same time the structure of the electron beam generating system is simplified by reducing the number of component parts. Instead of each time three rings there are in-serted each time one or two parts in the "grid 4" and/or the "grid 3". If, in addition thereto, these parts are made from a soft magnetic material, and quite depending on the given shape, additional field-formers (shunts and/or enhancers) can be omitted.

Abstract: ABSTRACT         A signal processing system for processing dynamically varying intelligence-carrying signals represented by different frequencies by transferring these signals within a pass band narrower than the range of the frequencies.  The system makes use of a compressor circuit for compressing only signals within a predefined pass band.  Active filter circuits shape the compressed signals into a predetermined power envelope having fundamental frequency signal components and harmonically related constituents of the fundamental frequencies.  Another compressor circuit is used for further compressing signal constituents of the power envelope.  A negative feedback arrangement provides dynamic limiting of compression by the first compressor circuit as a function of increase of compression by the second compressor circuit.  A linear combiner is used to recombine the harmonically related constituents delivered by the second compressor circuit, and thus retrieve the dynamically varying intelligence-carrying signals.  The system involves a new method of signal processing involving first defining a range of original signal constituents to be processed including signal fundamentals and harmonically-related components of said fundamentals and then primarily dynamically compressing the range of original signal constituents. Signal component amplitudes of the dynamically compressed signal are selectively controlled to define a power envelope which is further dynamically compressed to provide processed signal constituents, but while providing time-delayed limiting of com-pressing of the original signal constituents.  The processed signal constituents are linearly recombined to reproduce the intelligence-carrying signals, recovering original frequencies quite beyond the pass band.
