Abstract: DEMETALLIZATION OF HIGH METALS FEEDSTOCKS         USING REGENERATED CATALYST     ABSTRACT     The demetallization of petroleum feedstocks contain-ing a high percentage of metal impurities, particularly vanadium, by ebullated bed catalytic hydrogenation is improved through an initial pretreatment of particulate activated porous aluminum oxide catalyst in a reaction zone wherein vanadium and carbon are deposited on the catalyst.  Following such pretreatment, the used catalyst is removed from the reaction zone at an appropriate rate, regenerated by burnoff of substantially all the carbon, and then returned to the reaction zone.  This use of regenerated catalyst results in the average demetallization activity of the catalyst in the reactor being higher for vanadium removal than if the used catalyst were all replaced with fresh catalyst.      While this invention may be used in a single stage ebullated bed reactor process, it is particularly useful as the first stage of a multiple state ebullated bed hydrogena-tion reaction process in which a high activity desulfurization catalyst is used in a subsequent reaction stage for sulfur removal.

Abstract: Docket M-295-C      PRINTING APPARATUS WITH INKING MECHANISM        Abstract of the Disclosure There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head and to which another cam is secured for driving an operating lever.  The operating lever is coupled to a slide which drives a feed finger and cam means for actuating an inker.  The travel of the feed finger is selectively variable by changing the position of the pivot on which the lever is mounted.  The cam means is part of a lost-motion connection which couples the slide to the inker.  As the operating lever is cammed in one direction to move the feed finger forward, the inker is moved into and out of inking cooperation with the print head assembly.  Because of the lost-motion connection adjustment of the pivot does not affect the length of travel of the inker.          When the inker is in inking position the inker is supported at both sides of the platen thereby leaving the platen accessible during threading of the apparatus with the web of record members.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for assembling an aerosol val-ve which are intended to assemble a valve made up of a valve body, a spring, a stem, a sealing disk and valve cap.  In assem-bling the valve, two vertically disposed sets are formed in a sequence indicated by their names which are the first "sealing disk-valve cap" set and the second "valve body-spring-stem" set.          Said sets are disposed one above the other so that their origin-al orientation is retained, the sets are brought together so as to place the components into the specified position relatively to each other in the valve and then the sets are interlinked by deforming  the valve cap. In the apparatus embodying said method, namely in a mechanism bringing the sets together, there is pro-vided a tip adapted to grip, transfer and dispose the first set above the second one.  By virtue of such arrangement, the assembling of valves involves a minimum of operations and a high-capacity apparatus has been developed.

Abstract: GRADE TRIMMER     ABSTRACT OF THE DISCLOSURE:         A grade cutting machine having an alongated main frame supported on three bogey-mounted individually driven endless tracks.          The cutting tool is rotatably mounted on an axis transverse the front of the main frame within an enclosing bowl.  A vertically adjustable moldboard is provided across the back wall of the bowl behind the cutting tool.  Two of the endless tracks are mounted on vertical non-rotatable axes on opposite sides of the main frame behind the moldboard and each is provided with an extensible frame-supporting member for automatic simultaneous or independent vertical adjustment.  The third endless track which can control the steering under certain conditions is provided with an extensible frame-sup-porting member connected for independent manually controlled vertical adjustment.  In one embodiment the drive means for the front pair of endless tracks are under the control of the steering function of the rear endless track so that, as a steering correction is made, the front endless track on theoutside of the curve is driven faster while the front endless track on the inside of the curve is driven slower, the speed differences being inversely proportional to the radius of the curve being negotiated.  A conveyor having a pivotal rear sec-tion under the control of dual rams through dual levers for deposit of the cuttings anywhere in a 180° arc is provided.  The moldboard is under the control of a pair of rams and carries both the grade sensor and the slope pendulum control whereby slope corrections are isolated from grade corrections.

Abstract: ABSTRACT OF THE DISCLOSURE      A method is disclosed whereby the molecules of a chemical substance to be measured, referred to as target molecules, are combined with fluorescent molecules having a relatively long fluorescent decay lifetime.  These tagged target molecules are excited with an intense pulse of ultra-violet or visible radiation, and a detection system is gated on only after background fluorescence has substantially de-cayed, but while the fluorescent tag attached to the target molecules is still actively decaying. The amount of fluorescent tag emission which is measured is indicative of the target molecule content of the sample  An apparatus for improved fluorescent spectrofluorometry includes a pulsed excitation source and a gating means connected to a detection system for gating the detection system on after tagged target molecules have been excited and competing back ground fluorescence has substantially decayed, but before tagged target molecules have substantially decayed.    A new family of fluorescent antibodies (FAB) and a method for their synthesis is disclosed for use in an apparatus and method wherein the effects of background flu-orescence are virtually eliminated from fluorescence measure-ments.  The novel fluorescent antibodies consist of anit-bodies conjugated with rare-earth chelates which have unique fluorescent properties.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention relates to an improved signal delay circuit. In both the transmit and receive circuits of FM communications systems, it is often necessary to delay a particular signal in order to improve the performance of the system. Prior art delay circuits are undesirable because of the high cost of elaborate generators, filters and phase linearity compensators required to eliminate their associated noise and resulting signal degradation. The present invention provides an improved delay circuit having low insertion loss and low phase distortion charac-teristics. This is accomplished by a bucket brigade device for sampling the signal and time delaying the samples, a sample-and-hold device for sampling and sorting the voltage levels of the individual delayed samples in succession, and a clock for developing timing signals for controlling the delay line and the sample-and-hold device.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed herein is a method for producing foamed articles, such as seat cushions for a riding lawn mower or the like, including the steps of providing a mold having at least two separable, electrically insulated mold sections which, when positioned together in a molding position, cooperate to define a molding chamber having the shape of the article, and providing a thin layer of an electrically conductive material on each mold section, which layer forms the molding surface and serves as a radio frequency electrode.  A foamable and heat curable material is introduced into the mold cavity and a radio frequency voltage is applied across the electrodes, and thus through the foamable and heat curable material, after the mold sections are positioned together in a molding position. The resultant internal heating of the material rapidly cures the material to a hardened condition without generating high internal pressure forces inside the molding chamber.          In one embodiment, a skin-forming material, such as a sheet or film of a flexible thermoplastic resin, is laid over the mold cavity of one of the mold sections and is vacuum formed into conformity with the contour of the molding section surface and a foamable and heat curable pad-forming material is introduced into the molding chamber on top of the skin-forming material prior to the application of the radio frequency voltage.
