Abstract: DREDGING SYSTEM AND METHODS OF DREDGING               ABSTRACT OF THE DISCLOSURE           A dredging system for excavating difficult-to-dig material wherein a cutterhead is supported on a boom mounted on a floatable vessel and a suction conduit communicating with a suction developing mechanism leads to the cutterhead housing.  The cutterhead housing is mounted for pivotal move-ment about a generally longitudinal axis on the longitudi-nally extending boom and has a vertically disposed rotary disc supported in the cutterhead housing forwardly of a material collecting compartment for rotation about a trans-verse axis.  At least one opening is provided through the disc and a knife is mounted on the outer face of the disc in a position to cut material and to propel it through the opening to the material receiving compartment from which it is moved into the suction conduit and removed to a remote location.  Because the cutterhead housing and its rotary disc are supported for powered pivotal movement on the boom about a generally longitudinal axis, the cutterhead can, at the ends of its sidewise paths of travel in each direction be turned stepwise end-for-end, cutting a path for itself as it moves to a position in which it can take a return cut at a lower level.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of generating graphic designs from a light source by scanning the light source to generate a video signal, generating signals representing parameters of a raster signal and generating a raster signal from the parameter signals.  The method further includes the steps of generating a modified video signal from the video signal and the raster signal, displaying the modified video signal as a visual display and reproducing the visual display as the graphic design.  The system for performing the method includes a light box which is scanned by a television camera to generate the video signal.  A special purpose computer is programmed with the parameters for defining the size, shape, position and structure of a raster signal which is then generated.  The video signal and the raster signal are combined by the computer to generate the modified video signal to a display means such as a cathode ray tube.  A still camera is utilized to photographically record the displayed signal as the graphic design.

Abstract: Abstract of the Disclosure A tube has one end portion supported within an opening in a heat-insulating wall and is fired by a dual fuel burner. Disposed within the one end portion of the tube is a combustion sleeve which extends the name of the burner inwardly beyond the wall and thereby prevents the insulated end portion of the tube from being burned out. An abrupt restriction is formed at the discharge end of the combustion sleeve and creates turbulence in the air/fuel mixture to promote cleaner and more efficient burning.

Abstract: ABSTRACT OF THE DISCLOSURE             The present invention is a method of swelling cell mem-branes of cells surrounding the latex containing vessels in the underpeel of bananas to enable these latex vessels to be more resistant to temperatures within the range of 45°F to 55°F. An oleaginous material having a specified viscosity is applied to the exterior peel while the underpeel is maintained at a temperature above 55° during the application for a dwell period of at least 24 hours to permit substantially all of the oleaginous material to penetrate below the exterior peel and and into the sites of the latex vessel cell membranes to swell the membranes to prevent both a phase change in the cell membranes and an increase in the permeability for the liquid and solutes of the cells surrounding latex vessels into the latex contained in these vessels.

Abstract: TITLE OF THE INVENTION    METHOD OF READING THERMOLUMINESCENT          DOSIMETER     ABSTRACT OF THE DISCLOSURE     A method of thermoluminescent dosimetry em-ploying infrared radiation heating of a dosimeter.  An in-candescent lamp is used for the source of infrared radiation.    The dosimeter is provided with a infrared radiation absorbing layer connected thermally to a thermoluminescent material layer.  The infrared radiation absorbing layer is irradiated with infrared radiation so that thermoluminescent material is not directly irradiated.  The lamp is initially powered whereby the dosimeter is heated by infrared radiation of such high intensity as to tend to cause a heat equilibrium in the dosimeter above the temperature where thermal radiation is generated from the dosimeter.  Then the power supplied to the lamp is cut or decreased, so that the dosimeter is heated by the afterglow of the lamp.  Therefore the rate of temperature rise of the dosimeter becomes quite slow in the latter half of heating process, whereby the temperature of dosimeter easily falls into the required range.

Abstract: ABSTRACT A nutritious vegetable seed solubles binder for animal feed blocks. The subject vegetable seed solubles contains about 80% by weight carbohydrate and up to about 24% protein on a dry substance basis. The new binder may be used as a complete or par-tial replacement for cane molasses as a binder in animal feed blocks, including those such as molasses/salt blocks, medicated feed blocks and high protein feed blocks. The subject vegetable seed solubles may also be combined with soybean hulls, bagasse or such similar material to make an ingredient which is then used to make animal feed blocks. The subject binder has proven especially useful for binding a high energy protein block. The resulting block is more easily formed, and the binder contributes a resilient flexible effect to the block. Such blocks not only weather better outdoors, but they also are consumed more uniformly over a longer period of time by the livestock. The presently preferred binder is condensed soybean solubles which is a by-product from the manufacture of soy protein concentrate by a hexane/aqueous alcohol extraction process. Other vegetable seed solubles binders can also be used, including the vegetable seed solubles from other soybean processes, cottonseed, rapeseed, sesame seed, safflower seed, sunflower seed, peanuts, maize, yellow field pea and horse bean. A typical feed block made according to the subject invention may include a combination of the following ingredients: dried steep liquor concentrate (DSLC), soybean meal, salt, conden-sed soybean solubles, animal fat, dicalcium phosphate, minerals, and vitamins.

A removable wall of expendable material such as ordinary masking tape is applied to the other two sides, extending between the ends of the side plates to form a shallow pan which is filled with a liquid adhesive.  The pleated filter media is attached along its two side edges to side wall members having notched ends for mating with the side plates of the end assemblies.  One edge of the filter media between the two side walls is immersed in the pool of adhesive and the side walls are attached to the side plates.  After the adhesive hardens, the masking tape is removed and the other end assembly is attached in the same manner.

Abstract: Abstract A magnetic circuit useful in crossed field tubes and the like.  At least one permanent magnet assembly is provided which includes a high flux density magnet (as Alnico), a high coercive force magnet (as Samarium Cobalt) with an end area larger than the facing end of the high flux density magnet, and polarized oppositely thereto, and an iron transition member sandwiched between the two magnets. this isiolates the high coercive force magnet and concentrates its flux.  When used with a second such magnet assembly to create a high magnetic flux density in a gap therebetween, for example, in the interaction space of a crossed field tube, a higher flux density is achieved in the gap than would be the case utilizing the high flux density magnet alone within the available dimensional limitations.  This  is particularly so in an open magnetic circuit application having only a non-magnetic flux return path.
