Abstract: A residuum oil solvent extraction process is improved by using direct fired convection heaters for heating the asphaltene, the solvent-deasphalted oil phase, the deasphalted oil and the stripping steam, instead of hot oil heat exchangers. The convection heaters are fired using recirculated flue gas so that the hot flue gas supplied to the convection heaters has a temperature between 800.degree. F. and 1400.degree. F.

Abstract: Defoaming formulations for aqueous systems are produced by treating silicates such as sodium magnesium aluminosilicates with a source of aluminum to provide an aluminum content therein in the range of 0.1 to 2.5 wt. %, preferable 0.3 to 1.2 wt. %, and forming a defoaming formulation from said aluminum treated silicate by hydrophobizing with a silicone fluid, and dispersing in oil and/or water to form a defoamer formulation.

Abstract: A method of inhibiting the production of mycotoxins of fungus, such as aflatoxin-producing and sterigmatocystin-producing fungi, in plants susceptible to contamination by such mycotoxins consists of introducing into the susceptible plant a gene encoding for lipoxygenase pathway enzyme of the mycotoxin. Exemplary of the lipoxygenase pathway enzymes are soybean lipoxygenase, allene oxidase, hydroperoxide lyase and hydroperoxide dehydratase. The resulting transgenic plant demonstrates substantial resistance to mycotoxin contamination of such fungus. Plants which are substantially resistant to mycotoxin contamination of Aspergillus spp. are further obtained by incorporating into mycotoxin susceptible plant antisense genes for the 9-hydroperoxide fatty acid producing lipoxygenases.

Abstract: This composite pipe (20) is of the type including an inner tube (2) made of a first thermoplastic material (A), a reinforcement (21) including a metal tape (3) bonded to the inner tube by a first adhesive (61) compatible with the first thermoplastic material, an outer sheath (4) made of a second thermoplastic material (B), bonded to the reinforcement (21) by a second adhesive (62) compatible with the second thermoplastic material. According to the invention the two materials A and B have different chemical natures and, in the connecting region 22 between the strips opposite one another 61a, 62a, respectively, of the first and of the second adhesive, a means of bonding joins these two bands coherently. In an embodiment this means of bonding consists of adhesives which are different but compatible and co-crosslinked with each other.

Abstract: An improved finely divided rubber-reinforcing clay mineral composition can be produced by employing a hydrous kaolin clay surface treated with a functional silane, a methylene donor compound such as hexamethylenetetramine, and a multifunctional methylene acceptor such as resorcinol. A novel process of preparation is provided. The improved reinforcing, treated clay filler can be combined with natural or synthetic elastomer compositions which can be cured to elastomer products which have improved physical properties, such as modulus, tensile, tear, wear resistance and/or resistance to heat build-up.

Abstract: A moist-heat sterilization apparatus is provided which comprises a boiler shell (3), a chamber (4) inside said boiler shell (3), a heating block (14) external to said chamber (4) and in contact with the boiler shell (3), a feeding circuit (12) to supply the heating block (14) with water, and a conveying circuit (26) extending between the heating block (14) and chamber (4), the heating block (14) comprising canalization members (31) interposed between the feeding (12) and conveying (26) circuits and heating members (30) adapted to create a first steam flow through the canalization members (31). The process consists in admitting a first steam flow into a boiler shell, collecting the condensation water of the first steam flow and heating the boiler shell in such a manner that a second steam flow is produced from the condensed water.

Abstract: The preferred embodiment provides an electronic learning aid which includes a housing having a hand pad that is sized and shaped to receive a child's hand. The hand pad has five finger portions with each having a finger switch embedded therein that is positioned to be actuated by the child's finger. An indicator is mounted in close proximity to and associated with each finger portion to indicate the appropriate finger to be depressed on the hand pad. A keyboard assembly, having an abbreviated keyboard, is also mounted on the housing. A light emitting diode is mounted directly beneath each white key so that each white key can be illuminated to indicate the appropriate key to be depressed. A microcomputer having a speech synthesizer provides instruction to the student and controls the operation of the electronic learning aid.

Abstract: A new process is described for the production of 6-alpha-amino-penicillins and 7-alpha-amino-desacetoxy-cephalosporins free from halogen-containing solvents by acylating 6-APA, 7-ADCA or a derivative thereof in a halogen-free solvent.

Abstract: Apparatus for balancing and lifting a load supported from opposite ends of a cable or chain and which includes a sheave engageable by the cable or chain and through which extends a pin member. The pin member is radially offset from the center of the sheave and is supported, at opposite ends thereof, by structural members which may be attached to a source of lifting power.

Abstract: A projectile having a longitudinal axis, a sensor disposed in the substantially pointed front end of the projectile for detecting a respective target, and electronics connected to the output of the sensor for igniting a correction charge to effect a correction of the flight path of the projectile by a predetermined angle (.delta..sub.0). In order to install the apparatus for flight-path correction into the respective projectile completely and in a space-saving manner, so that, unlike in known projectiles, corresponding evaluation and signal-transmission units in the respective weapon carrier can be omitted and complicated gyroscopic systems in the projectile can be omitted, the sensor determines the angle (.delta.) between the longitudinal axis of the projectile and the line (target line) connecting the projectile and the target, and when an angle (.delta..sub.0) is reached that is identical in size/magnitude to the deviation caused by the respective correction charge, the electronics ignite this charge.

Abstract: The invention relates to a method by which expression cDNA clone banks are screened by means of IgE antibodies derived from the sera of allergic individuals, or by means of monoclonal or polyclonal antibodies. This type of screening is used for the detection of polynucleotides whose open-reading frames code for allergenically active proteins. These proteins are characterized in that their biological activity as allergens is equal to that of plant allergens occurring in nature.

Abstract: A robust and frequency-economic point to multipoint radio access microwave system combines the use of only two frequency bands and alternating polarizations. Base station antennae feeding adjacent sectors from a common base station site operate at least with different ones of two sets of channels. Moreover, sectors at adjacent base station sites (e.g., in adjacent cells) which are aligned with the sectors of the first base station site employ either a different set of channels or differing polarization. The two sets of channels can be two sets of frequencies (e.g., FDMA).

Abstract: An intrinsically safe data acquisition system is disclosed for use in hazardous locations. The system includes a driller's console that itself is intrinsically safe and includes a large LCD monitor, keypad and local CPU. The system further includes satellite data acquisition and processing boxes that are also intrinsically safe and that are located within the hazardous area. Each satellite box includes its own CPU and acquires and locally processes signals received from a number of field sensors. The satellite box converts the signals into digital form, and transmits the data via a fiber optic communication channel to a master CPU box located in an unclassified area. A high current intrinsically safe barrier distributes power from the master CPU box to the satellite box for powering all the sensors supported by that satellite box. Another such barrier distributes all the power required by the driller's console.
