Abstract: ABSTRACT OF THE DISCLOSURE     Movable insulation is provided with sealing structural components to minimize or eliminate for practical purposes infiltration and convection currents in and around the movable insulation to enhance the thermal insulating quality of the assembly.  Seal strips on the edges of the insulation pocket forming material layers are adapted to slidingly engage seal guides provided in the side frame channels of the assembly to seal the sides.  Weight bars in the lower extremities of the insulation forming material sheets enhance the seal on the bottom as well as to keep the layers of material separated, and rotatable separating rollers on top also help to keep the layers separated and to form a seal on top.  A smooth operating manual chain drive and anchor mechanism is provided, as well as a removable decorative fabric for the front of the assembly.  Alternative embodiments enhance the seals and insulating quality of larger movable insulation assemblies, including top seal guide extensions for separating the layers, a bottom curved seal guide for accommodating the lower ends of edge seal strips to prevent binding and loss of bottom seal by accommodating differential length movement of front and rear layers, and edge seals for inner layers adopted for sealing edges as well as for maintaining layers separate in non-vertical applications.

Abstract: ABSTRACT OF THE DISCLOSURE A method of recovering molybdenum oxide by oxidation of a molybdenum sulfide concentrate contaminated with impurities wherein the concentrate having an average particle size in the range of 20 to 90 microns is suspended to form an aqueous suspension which is oxidized at elevated temperature and elevated oxygen partial pressure in an autoclave,  The suspension withdrawn from the autoclave is filtered to remove the molybdenum oxide from the primary filtrate containing sulfuric acid and this filtrate is neutralized with lime to form calcium sulfate which is then removed from the suspension to provide a second filtrate.  According to the invention, only the second filtrate is recirculated at a rate such that the suspension density in the oxidation stage is between 100 to 150 g of solids per liter and this suspension density is maintained in the oxidation stage by the recirculation.

Abstract: INVENTION: CASTING CAR FOR SUPERHEATED            MATERIALS        INVENTORS: ROBERT THIEL AND EDWARD BIELAWSKI            ABSTRACT OF THE DISCLOSURE           The invention provides a casting car for use in removing super-heated molten materials from an electric arc melting furnace.  The cooling car has a metal frame which includes a shallow container adapted to receive the molten materials.  A relatively permanent refractory lining protects the interior surface of the container, and a replenishable, granular refractory material is deposited over the permanent refractory lining.  Heat deflectors extend upwardly from the metal frame about the top of the container in order to channel heat radiated from the interior upwardly whereby melting plant equip-ment and personnel located near the cooling car are not subjected to very intense radiant heat.  Wheels are secured to the bottom of the metal frame to permit the cooling car to be rolled along the track leading to the melting furnace to receive the super-heated molten materials.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a process for deactivat-ing enzymes in fruit and vegetables, and to plant used there-for, tomato  eing the example adopted.  The process basically speaking is one of feeding-in whole tomatoes under vacuum, chopping or mashing them in conditions where residual oxygen is reduced to a minimum, depending upon the degree of vacuum obtainable inside the feeder-tank, and then introducing the tomato in its triturated state into a pressurized system or circuit operating at whatever temperature represents the optimum for enzyme-deaetivation; the introduction of freshly-mashed deaerated tomato into the circuit being such that it mingles with tomato already heated and circulating therein. Plant for carrying such a process into effect comprises a closed circuit operating either at atmospheric or applied pressure, in which heated tomato is caused to circulate by means of a pump, and a mincer which chops up the raw produce in conditions where attendant oxygen is minimal, prior to its entry into the circuit; also, a heat exchanger for raising the temperature of tomato circulating within the system, a pump for propulsion of the produce thereinto, and a pump for drawing off the ensuing product therefrom.

Abstract: Abstract Method of determining an operating path of a tool Information concerning the path of an adhesive-applying nozzle (28) and/or a lasting roller (176) relative to a three-dimensional shoe bottom surface is obtained using a flat insole in combination with a grid of flexible transparent material.  The grid has a datum (10), a center line (12); (representing a linear path of a tool carrier (26)) and a plurality of transverse lines (14), the spacing between each pair of adjacent transverse lines representing unit time.  The transverse lines adjacent to the datum are more closely spaced than those beyond, the principal component of movement of the tool (as opposed to the tool carrier) in relation to the shoe bottom, at the datum (i.e. the toe end), being widthwise rather than lengthwise.  Heel height information may also be supplied to the computer, which is programmed to modify the digitized information accordingly for the region from the ball region to the heel (which constitutes some 60% to 65% of the overall shoe length).  The information may also be modified according to the particular arrangement of the nozzle and roller supports.

Abstract: ABSTRACT Apparatus for monitoring and storing heart activity signals is disclosed as including a data processor illustra-tively in the form of a digital microprocessor.  The monitoring and storing apparatus comprises a memory comprising first and second pluralities of storage locations, a circuit operating in a real time frame for sampling at a regular rate the patient's heart activity and for storing such sample signals in corres-ponding locations of said first plurality, and the data pro-cessor for processing the signals stored in the first plurality and for storing the processed signals in selected locations of said second plurality.  The storage of the signals in the second plurality is performed in a second computer time frame and at a rate faster than the real time sampling rate.  A sampling clock provides a sampling clock signal to the sampling circuit whereby the samples of the patient's heart activity are taken.  A second computer clock provides computer clock signals to at least a portion of the data processor whereby the processing of the heart activity is effected in the relatively fast computer time frame.  The data processor comprises a first portion or means that operates in response to the sample clock signal for evaluating the heart activity signals to determine the existence of a valid heartbeat and a second portion operating in the computer time frame for processing the detected heartbeat and in particular for determining the interval therebetween, which is evaluated to determine whether the heartbeat is occurring with a regular rhythm or not.

Abstract: ABSTRACT           The raster scanned by a television receiver deflection circuit (36) is subject to an increase in size resulting from a decrease in high voltage level caused by increasing electron beam current.  The receiver comprises a switched mode power supply (16) producing a voltage that is used to power the deflection circuit (36) and generate the high voltage.  The voltage supply level incorporates an ac ripple component caused by loading on the supply due to increasing beam current.  A peak detector (69) senses the peak level of the voltage supply and applies it to a regulator control circuit (52) which maintains the peak level of the supply voltage constant.  Increasing beam current loads the supply, decreasing the average dc voltage level applied to the deflection circuit (36), thereby decreasing the electron beam scan to compensate for a reduction in high voltage level.
