Abstract: A low cost process for the high yield recovery of wheat gluten and starch is provided which comprises initially pearling whole wheat kernels to remove germ and a part of the bran, followed by grinding to an average particle size of 100-400 microns. The ground, pearled wheat is then subjected to wet processing to isolate gluten and starch. Yields of gluten are 20-25% higher than yields using flour as a starting material.

Abstract: An intracatheter pump apparatus and method is described for infusing fluids through a lumen of a catheter. The intracatheter pump includes a motor or power source on the outside of the catheter which causes movement of a fluid moving mechanism positioned in the lumen of the catheter, the fluid moving mechanism being attached to the distal end of an elongated member which in turn is attached to the motor.

Abstract: Novel thioimidazoles are 5-carboxyaldehyde-1-methyl-4-(phenylmethyl)thioimidazole and 5-(.alpha.-aminoacetyl)-1-methyl-4-(phenylmethyl)thioimidazole acid addition salt. The latter is prepared from the former by steps comprising Grignard addition to form 5-(1-hydroxyethyl)-1-methyl-4-(phenylmethyl)thioimidazole, oxidizing the hydroxy compound to form the corresponding ketone, brominating under acidic conditions to form the bromoacetyl derivative, converting the bromo in the bromoacetyl derivative to N,N-diformylamino and then hydrolyzing. The latter thioimidazole is an intermediate for forming 5-methylimidazo[4,5-e]-1,2-thiazin-4(5H)-one, that is neamphine, and for forming 3-chloro-(5-methylimidazo) [4,5-e]-1,2-thiazin-4(5H)-one, that is 3-chloroneamphine.

Abstract: An apparatus is disclosed to optically determine which of four fluorophores is attached to a band of DNA molecules on an electrophoresis gel.

Abstract: A soil desorption device and method which utilizes an easily manufacturable and assemblable pressure cell to contain soil samples. The pressure cells are in turn easily attachable to pneumatic pressure manifolds and can be independently valved. The cells are also easily adapted to be connected to collection containers for any desorbed fluid. Each cell utilizes a cylindrical container having rubber gaskets at opposite ends and which can be sandwiched between top and bottom plates to seal the container. A thin nylon membrane having small pores is positioned at the bottom of the container and the bottom plate has apertures to allow fluid forced through the membrane to pass to the fluid collection devices. This cell presents low impedance to fluid flow, produces high flow rates, and allows maintenance of good seals and accurate pressurization of each cell. These and other features and advantages allow for more economical and better soil desorption procedures and soil hydraulic characteristic measurements.

Abstract: A gene which codes for the protein apoaequorin is disclosed along with recombinant DNA vectors containing this gene.

Abstract: A selectively-sized, raw, low-rank coal is processed to produce a low ash and relative water-free agglomerate with an enhanced heating value and a hardness sufficient to produce a non-decrepitating, shippable fuel. The low-rank coal is treated, under high shear conditions, in the first stage to cause ash reduction and subsequent surface modification which is necessary to facilitate agglomerate formation. In the second stage the treated low-rank coal is contacted with bridging and binding oils under low shear conditions to produce agglomerates of selected size. The bridging and binding oils may be coal or petroleum derived. The process incorporates a thermal deoiling step whereby the bridging oil may be completely or partially recovered from the agglomerate; whereas, partial recovery of the bridging oil functions to leave as an agglomerate binder, the heavy constituents of the bridging oil. The recovered oil is suitable for recycling to the agglomeration step or can serve as a value-added product.

Abstract: A process for converting starch or partially hydrolyzed starch into a syrup containing dextrose includes the steps of saccharifying starch hydrolyzate in the presence of a saccharifying starch hydrolyzate in the presence of a mutated glucoamylase or related enzyme and increasing the selectivity of the enzyme for .alpha.-(1.fwdarw.4)-glucosidic bonds by the glucoamylase or related enzyme by including at least one mutation, the mutation substituting an amino acid of the enzyme with at least one amino acid chosen by comparison with structurally related regions of other enzymes that selectively hydrolyze only .alpha.-(1.fwdarw.4) glucosidic bonds.Enzymes made in accordance with the present invention are also disclosed.

Abstract: A method for preparing biodegradable microspheres having a three-dimensional network in which biologically active macromolecular agents are physically entrapped therein. The microsphere is able to degrade and release the macromolecular agent at a controlled rate. The method involves emulsifying a vinyl derivative of a biodegradable hydrophilic polymer, a water-soluble monovinyl monomer and a biologically active macromolecule in water, and copolymerizing the biodegradable hydrophilic polymer and the water-soluble monovinyl monomer such that the biologically active macromolecule is entrapped therein.

Abstract: An energy beam position detector including a shape memory alloy wire positioned at a boundary of acceptable beam trajectory. The wire is held under adjustable tension. A contraction detector monitors contraction of the wire. If the beam strays, is misaligned, or spreads and strikes the wire, the contraction detector can actuate a switch to alert personnel, shut off the beam, or can exert a force to enable other remedial action be taken.

Abstract: Multi-layer heterostructure transistors, and methods for making them, involve the use of a p+ doped GaAs gate for an n-channel device to increase barrier height and reduce turn-on threshold. A p++-i-p substrate helps to reduce source and drain capacitances and control short-channel effects. Use of one relatively high temperature photoresist in the fabrication process facilitates alignment of ohmic contact depositions with the source and drain regions.

Abstract: A ponded infiltrometer including a bubble chamber formed in a base that supports a liquid reservoir. A single valve interposed in a channel between the bubble chamber and the reservoir controls both air flow into the device and water flow out of the device. A selectively movable bubble tube communicates between the bubble chamber and the atmosphere, and the position of the lower end of the bubble tube precisely regulates the amount of ponded water in the containment ring which contacts a section of soil. The base and attached reservoir are supported and secured above the containment ring by an adjustable tripod.

Abstract: Methods and systems are disclosed for encapsulating viable cells which produce biologically-active factors. The cells are encapsulated within a semipermeable, polymeric membrane by co-extruding an aqueous cell suspension and a polymeric solution through a common port to form a tubular extrudate having a polymeric outer coating which encapsulates the cell suspension. For example, the cell suspension and the polymeric solution can be extruded through a common extrusion port having at least two concentric bores, such that the cell suspension is extruded through the inner bore and the polymeric solution is extruded through the outer bore. The polymeric solution coagulates to form an outer coating. As the outer coating is formed, the ends of the tubular extrudate can be sealed to form a cell capsule. In one embodiment, the tubular extrudate is sealed at intervals to define separate cell compartments connected by polymeric links.
