Abstract: CAPACITOR WITH NON-NOBLE METAL ELECTRODES AND METHOD OF MAKING THE SAME                    Abstract of Disclosure A ceramic  capacitor having electrodes. The capacitor is formed by cosintering layers of ceramic dielectric and layers of non-noble metal material indifferent to the dielectric layers corresponding in area and position to the electrodes. The indifferent layers are converted to a conductive state, for example, by chemical conversion and used as such or are removed and replaced by metal or conductive material. One example in which the indifferent layers comprise nickel oxide involves stacking layers of green ceramic coated with nickel oxide in the desired electrode pattern, sintering the stacked layers to produce a monolith, reducing the nickel oxide in the monolith to metallic nickel in a hydrogen atmosphere at a tem-perature low enough to have minimal effect upon the dielectric properties of the ceramic and using the metallic nickel as reduced for the ceramic capacitor electrodes. In another ex-ample, after the reduction step ( which may be at high tempera-ture) the metallic nickel is dissolved, for example by sulfuric acid, the ceramic monolith is reozidized by firing in an oxi-dizing atmosphere such as air, and the voids left by removal of the dissolved metallic nickel are provided with suitable electrodes. In still another example, in which the indifferent layers comprise oxidizable material such as carbon, the stacked layers are sintered in an inert atmosphere to produce a mono-lith of matured ceramic and the indifferent layers are removed by subsequent firing in an oxidizing atmosphere to produce the voids for receiving conductive electrode material.

Abstract: FILTRATION METHODS AND APPARATUS               ABSTRACT OF THE DISCLOSURE       Filtration in an internal rotary filter system  is improved by externally impacting the filter screen as it rotates with a programmed spray of liquid that is varied from a relatively low to a relatively high pressure.   In certain instances, this programmed spray is controlled by an electric timer circuit so arranged that the high pressure spray is on for a period of time which does not too unduly burden the system with fluid, but which is sufficient period of time to prevent slime formation on the screen.  This can for instance keep the screen free of slime when no germicidal agent (e.g. Cl2) is employed.

Abstract: LEG LEVELING DEVICE      Inventor:   Gerard J. Berkowitz ABSTRACT OF THE INVENTION DISCLOSURE In a preferred embodiment of the present invention, there is provided a leveling device for semi-automatically leveling and locking a plurality of legs of a legged unit such as a washing machine, a stepped ladder, or the like.  In this most preferred embodiment, each leg spring biased in a down-ward direction is clamped by a cylindrical sleeve of which half of the cylindrical wall thereof is pivoted on the other half, and is pressible such that the large surface of the sleeve is frictionally engaged with the leg in the locked state thereby providing secure frictional binding of the leg against further axial movement because of weight and/or vibrations of the articles such as a washing machine, and in conjunction with such clamping mechanism of a sleeve, there is provided a lever which includes in and as a part of the lever flanged male and female mated sections thereof biased apart by a strong spring such that upon withdrawal of the lever the pressure on the clamping mechanism of the sleeve is relieved but upon pressing forward of the lever, a firm and constant pressure is exerted against the pivoted clamping wall by virtue of the spring of the lever, the spring of the lever making it unimportant for the lever to be of any exact length, this being particularly important in view of the presence of a common pressure applying and pressure releasing lever for each of a plurality of the levers leading to different legs, in such a situation the actual length of these leg levers being slightly different from one another when connected to the central pressure applying and pressure releasing latching lever.

Abstract: ABSTRACT OF THE DISCLOSURE         A vessel adapted to receive, or discharge, heavy pieces of cargo moved in a horizontal plane, from or to an embankment, suffers a sudden change in displacement, when the weight of said cargo is transferred from the embankment to the ship, or vice versa.  This sudden transfer of weight alters the relative position be-tween the deck and the embankment, and makes a smooth handling of the cargo impossible.  The present invention provides means for temporarily increasing the buoyancy of the vessel, at least on the portion thereof facing the embankment, to a value at least corresponding to the cargo weight to be handled, as well as fur-ther means for retaining the deck level with the embankment, irr-espective of the increased buoyancy.  The buoyancy increasing means may be trimming tanks formed integral with the vessel and arranged to always remain below water level, or may be a separate pontoon remaining at the embankment.

Abstract: Abstract of the Disclosure A high voltage power supply system particularly adapted for rapid switching of high voltage applied to an anode of a beam penetration color cathode-ray tube.  Energy for making the rapid transition between voltage levels is stored in two energy storage inductors, one for upward transitions and the other for downward transitions.  When it is desired to change the voltage applied to the cathode-ray tube, the appropriate one of the storage inductors is coupled through a controlled switch to the anode causing the voltage applied to the anode to change at a rapid rate.  The voltage rises until the de-sired voltage level corresponding to a desired output color is reached at which time the switch is turned off and the storage inductor recharged.  A tracking high voltage supply maintains the anode at the predetermined voltage level once that level has been reached.  Gain compensation is applied to the deflection amplifiers within the system so that patterns displayed upon the cathode-ray tube have a constant size inde-pendent of the voltage applied to the final anode of the tube.

Abstract: ABSTRACT OF THE DISCLOSURE     A draft gear carrier attached to the lower flanges of a hat shaped center sill comprises a flat steel plate to which are connected first and second slide or wear plates which extend substantially the width of the center sill.  The slide plates are substantially identical and, in assembling of the carrier, proper assembly is assured since the carrier is reversible and either slide plate will properly support the draft gear.  Upon predetermined wear to the first side of the carrier, resulting in an arcuate depression in the first side flanked by unworn, thick lateral edge portions, the carrier may be reversed, whereupon the arcuate depression faces downwardly and defines an upwardly arch-like depression centered between the unworn strength imparting thick edge portions which serve as buttresses for the arch-like depression.

Abstract: ROTATING-COMPENSATOR ELLIPSOMETER     ABSTRACT OF THE DISCLOSURE      Plane polarized light is reflected from a surface of a sample film to produce an elliptically polarized reflected beam.       The reflected beam is passed sequentially through a rotating one-quarter wave plate and a fixed analyzer which transmits a beam whose intensity varies as a function of the rotational angle of the plate.       The transmitted beam impinges upon a photodetector which produces an electric signal proportional to the intensity of the transmitted light.  The rotating one-quarter wave plate cyclically varies the polarization of the beam, so that the electrical signal, when numerically Fourier analyzed, provides Fourier coefficients having both sin.DELTA. and cos.DELTA. terms, where the ellipsometric parameter .DELTA. is the instantaneous phase difference between the parallel (RP) and per-pendicular (RS) components of the electric vector of the elliptically polarized reflected beam; therefore, the phase difference .DELTA. is uniquely and unambiguously defined in a single measurement.  Further-more, the presence of both sin.DELTA. and cos.DELTA. terms permits .DELTA. to be determined more accurately than is possible with the prior art ro-tating-analyzer ellipsometer.  Since the ellipsometric parameter ? is also uniquely defined ( ), properties of the sample film can be computed.  Alternatively, the rotating quarter-wave plate may be placed in the path of the incident plane polarized beam.
