Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a metallic screen cloth system, which can be used as a filter for dust aerosols and/or as a support matrix for catalysts in exhaust gas puri-fying equipment of internal combustion engines.  This system comprises superposed corrugaged or concentrina layers of screen cloth which alternate with flat layers of sheet metal or screen cloth and are piled  so as to form a stack of per-meable to gas or wound spirally as a coiled body permeable to gas.  On its opposite front ends  the parcel or the coiled body is closed by cover means such that a closed front end portion lies opposite an open front end portion so that exhaust gas entering at open front end portions is forced to pass over the entire length of the matrix through the screen cloth meshes into channels assigned to an open opposite front end portion.

Granted: 1985-05-28
Abstract: ABSTRACT OF THE DISCLOSURE     A pulse improvement circuit for a magnetic readback system produces a data representative signal having symmetrical, equal-amplitude pulses of limited time widths. The circuit includes an equalizer made in accordance to a final transfer function produced as a result of a mathematical convolution of first and second transfer functions. The first transfer function is based on the theory of a matched filter for receiving a signal having data representative and non-white noise pulses contained therein to produce a filter signal having maximum signal to noise ratio. The second transfer function is based on the theory of a Papoulis window function for slimming the pulses contained in the filter signal. A specific circuit implementation of the final transfer function is an eight-pole, inductor-capacitor, ladder network for amplitude equalization coupled to an inductor-capacitor, lattice network including first and second order sections for phase equalization.

Abstract: PHD. 80-103               9 ABSTRACT:            For radio communication with submarine vessels frequency ranges with very low frequencies are used. Even at these frequencies the penetration depth in salt water is only approximately 10 to 20 metres.  In order to improve the signal noise ratio or to extend the sub-merging depth use is made of buoy antennas connected to the submarine vessel by a cable.  In order to improve the manoeuvrability of the submarine vessel and to avoid the use of an active control system in the antenna, the antenna is constructed as a torpedo-like hollow body, which at the trailing part is equipped with two hydrofoils resembling a horizontal tail unit, which hydrofoils inter-connect the top and bottom of the body to each other as an open arc.  Both in the floating body and in the hydrofoils a loop of a crossed-loop antenna is incorporated, which loops are tuned in order to increase the sensitivity.  Sig-nal transmission to the submarine vessel is effected via an optical fibre guide, which also transmits the traction force.

Abstract: ABSTRACT During transmission of orthogonally polarized waves, cross-polariza-tion interference resulting from the non-spherical nature of rain drops can arise.  To eliminate this interference a special circuit has been designed. This elimination circuit includes a crosstalk component adder which has a weighting circuit for multiplying an interference component of the received orthogonal cross-polarized  signals by a compensation coefficient and a compen-sating adder for adding the output of the weighting circuit to a desired one of the received orthogonally-polarized signals.  The elimination circuit also includes an error detector for detecting the difference between a transmitted signal and the desired one of the received signals on the basis of the output of the cross-polarization crosstalk component adder.  Further component of the elimination circuit are an oscillator for generating cyclic infinitesimal signals; a correlator for detecting any correlation between the output of the oscillator and that of the error detector; and an integrator for integrating the output of the correlator.  Finally, the elimination circuit includes a control unit for adding the output of the integrator to that of the oscillator and sup-plying the sum as the compensation coefficient for the weighting circuit of the orthogonal cross-polarization component adder.

Abstract: Abstract of the Disclosure Shaped products of a 3A zeolite are formed either as beads or extrudates without any binder remaining.  In the case of beads, a 4A powder is mixed with a caustic solution and a metakaolin clay binder to form beads.  The beads are converted to a binderless 4A product which is given a partial calcium exchange followed by a potassium exchange to obtain the desired 3A binderless bead.  The 3A extrudates are produced by forming binderless 4A extrudates from a 4A powder and clay mixture that contains 40-60% by weight clay.  These binderless 4A extrudates are then given a potassium exchange.  Both the beads and the extrudates can be used to dry a mixture of a hydrocarbon compound such as ethylene and water.

Abstract: SELF-ALIGNED POWER MOSFET WITH INTEGRAL SOURCE-BASE SHORT AND METHODS OF MAKING           ABSTRACT OF THE DISCLOSURE         Double diffused power MOSFET's and methods of manufacture.  The source, base and drain regions of a double diffused power MOSFET correspond respectively to the emitter, base and collector of a parasitic bipolar transistor.  Double diffused power MOSFET's perform better when provided with an ohmic short between the source and base regions to prevent turn-on of the parasitic bipolar transistor.  In one form of ohmic short between the base and source regions, the source terminal comprises a metallic electrode, preferably aluminum, deposited over the source region, and the ohmic short comprises at least one microalloy spike extending from the source terminal metallic electrode through the source region and partly into the base region.  Such microalloy spikes are formed by heating the semiconductor substrate after the metallic electrode has been deposited under appropriate conditions.  In another form, a V-groove is formed by preferential etching in the source and base regions.  In particular the V-groove extends through the source region, with the bottom of the V-groove extending only partly into the base region.  A metallic source electrode is deposited over the source region and into the V-groove in ohmic contact with both the source and base regions to form both the source terminal and the ohmic short.  These two forms of ohmic short are integral in nature, and facilitates an overall MOSFET structure and manufacturing process characterized by a minimum number of masking steps, self-alignment, and increased active device area.

Abstract: ABSTRACT OF THE DISCLOSURE           A two speed hydraulic drive system for a boom mounted digger.          The system includes a three position directional control valve which directs fluid to and from tandem hydraulic motors.  In a low speed operating mode of the digger, a pilot operated valve is positioned to maintain the two motors in parallel.  In a high speed operating mode, the pilot operated valve is shifted by pilot line pressure to a posi-tion wherein the exhaust line of one motor is connected with a regen-eration loop leading back to the common inlet manifold of the motors, thus maintaining the motors in a condition with one motor idle and all fluid directed to the other motor.  The pilot line is controlled by a manually operated shift valve which effects shifting externally of the digger to minimize gear wear.
