Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for classifying desirable particles of powder metal by size and removing particles of undesirable material of a different density than the metal particles.  There is included a housing defining a closed flow path for a recirculated stream of protective gas different than ambient air.  A particle supply device introduces particles into the housing at a controlled rate in a downwardly falling stream.  A plurality of re-ceptacle trays are disposed in the housing generally vertically below the particle supply device with each tray having a forward lip positioned forwardly in the direction of the gas flow of the trays thereabove.  An electrostatic gas ionizer is disposed upstream of the particle supply device for ionizing the gas and a screen is disposed in the stream of gas between the ionizer and the particle supply device for attracting the ionized gas from the ionizer while allowing the passage of the gas through the screen for establishing the recirculated stream of gas to impinge the stream of falling particles to impart to each particle a horizontal component of velocity so that the trajectories of the particles will vary depending upon size and density thereof for falling into the various re-ceptacle trays.  Consequently, the desirable particles are classified by size, undesirable particles of a dif-ferent density than the desirable particles are removed or separated out, undesirable hollow particles are also removed or separated out, and because of the charge placed thereon, clusters of particles are broken up, i.e., the particles in such a cluster repel one another and separate.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed an apparatus for automatically maintaining the speed of a vehicle at a desired speed selected by the vehicle operator.  The apparatus includes one feedback loop for monitoring the actual vehicle speed and another feedback loop for monitoring the engine load. The engine load feedback loop enables the speed control to anticipate the effects of changes in engine load so as to minimize or eliminate undershoot or overshoot of the control system.  A signal representing the actual vehicle speed is combined with a signal representing the engne load to generate a composite feedback signal to a comparator circuit.  The comparator circuit compares the feedback signal with a signal representing the desired vehicle speed and generates control signals for maintaining the speed of the vehicle at the desired speed,

Abstract: (Case No. 7100) ABSTRACT OF THE DISCLOSURE    An inshot valve device for use with railway brake apparatus of the type employing a brake cylinder in which the chambers formed on opposite sides of the brake cylinder piston serve as storage reservoirs.  Braking force is obtained by the venting of air from the storage reservoir chamber on one side of the brake cylinder piston following movement of the piston to brake application position, so that the storage reservoir chamber from which air is vented is reduced to a minimum to conserve air.  During an emergency brake applica-tion, the air from this storage reservoir chamber is vented via the inshot valve device, which controls the emergency buildup of brake forces in accordance with a predetermined brake force profile.  The inshot valve device controls the emergency brake force buildup to follow this predetermined profile irrespective of different brake pipe charges or different service brake applications that may exist at the time of the emergency.

Abstract: ABSTRACT OF THE DISCLOSURE A method is provided herein for supplying solid, pulverized fuel to a pulverized-fuel pilot light of an annular flame, coal dust burner.  The method includes, firstly, supplying the coal dust burner with a fuel stream comprising a mixture of pulverized fuel and carrier air from a pulverizing plant via a main fuel supply conduit, that stream having a cross-section with areas of pulverized fuel having different grain sizes.  The second step involves selectively withdrawing a portion of the pulverized fuel and carrier air at a withdrawal site in the main fuel supply conduit which faces in the upstream direction with respect to the direction of flow of the stream so as to with-draw pulverized fuel of a grain size different from that comprising the cross-section of the entire stream.  The third step involves separating the with-drawn pulverized fuel from the carrier air and returning the carrier air to the main conduit at a location downstream from the site of the withdrawal. The fourth step involves feeding the withdrawn pulverized fuel to a storage bunker for a subsequent burning by the pilot light.  The fifth step involves feeding the withdrawn pulverized fuel from the storage bunker to the pilot light when the coal dust burner is extinguished wherein a flame is available for reigniting the coal dust burner when ignition is necessary.  The final step involves withdrawing additional portions of pulverized fuel as described above to keep a sufficient supply of pulverized fuel of selected grain size in the storage bunker for use by the pilot light when the coal dust burner is extinguished.

Abstract: ABSTRACT     A three dimensional interstitial catalyst support and a catalyst system comprising the support for use in (especially pressure-sensitive) surface reactions involving disturbed fluid flow, especially trickle feed three phase reactions such as the hydrogenation of crotonaldehyde or butyraldehyde.  The support comprises a three dimensional self-supporting form-stable inter-stitial (preferably knitted) wire (11, 23) structure (5, 20) in which the volume of the interstices (4a, 9a, 25, 26) is from 60 to 98 (preferably at least 85) % of the volume of the structure (5, 20). The combination of the use of wire, form-stability and an open structure allows disturbance to be imparted by the catalyst system with less risk of blockages, flooding or damage by attrition and hence less need to increase pressure during a reaction which is undesirable in pressure-sensitive reactions.  Also a method for making the structures (5, 20) by rolling up-wire cloth (1), compressing it to the pre-determined volume and annealing.          Also the use of the catalysts in disturbed fluid/solid/ catalysed reactions.

Abstract: DROP-ON-DEMAND METHOD AND APPARATUS USING CONVERGING NOZZLES AND HIGH VISCOSITY FLUIDS                      Abstract A drop-on-demand ink jet printing method and apparatus in which the print head has an ink cavity which is filled with ink, and which has a nozzle designed so that ink does not flow out under static conditions.  An electromechnical transducer is selectively energized in response to print data signals so that, when energized by an electrical signal, the transducer produces a pressure wave in the ink cavity sufficient to eject one ink drop from the nozzle for each signal above a threshold value.  The nozzle is a strongly convergent nozzle and the ink has a viscosity up to 100 centi-poise.  In the preferred embodiment, the nozzle is formed by anisotropic etching in a silicon substrate. An array of print heads produces a line of high-resolution printing as the print head array is moved across a print medium.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention is directed to a container for the long-term storage of radioactive materials such as irradiated nuclear reactor fuel elements.  The container is made of a material such as steel, cast steel or the like.  The container includes a vessel having an opening at one end for receiving the radioactive material stored therein and a cover which is welded to the vessel for closing the same.  In this container, the base material provides the mechanical strength and stabil-ity.  To make the entire container resistant to corrosion, the vessel and cover are provided with respective weld platings at the partition interface of the container.  The weld platings are made of cold-weldable, corrosion resistant material and are applied by the surface-layer welding process.  Corrosion protective layers are formed on the outer surfaces of the cover and vessel, respectively, and cover the outer surfaces up to the region of the weld platings.  The corrosion protect tive layers are preferably made of graphite, ceramic or enamel. After the weld platings and corrosion protective layers are applied, the cover and vessel can be placed in a hot cell wherein the vessel is filled with radioactive material.  There-after, the cover is joined to the vessel with a weld made of cold-weldable material applied to the weld platings at the partition interface.  A follow-up heat treatment is unneces-sary and operations in the hot cell are kept simple and to a minimum.
