Abstract: A process for carrying out chemical reactions in the gas phase or gas-liquid phase comprises feeding the chemical reagents under pressure into the combustion chamber of a turbine engine, where they react to form a desired chemical product. The heat energy evolved in the process can be utilized through the action of the turbine to power auxiliary equipment attached to the turbine engine, such as an electrical generator. In another embodiment, the turbine engine is utilized to carry out at least two reactions: a primary reaction which occurs in the combustion chamber of the engine, and a second reaction which occurs in an augmentor-section of the engine, utilizing the product of the primary reaction as a reagent in the production of a final product.

Each compartment preferably has an open upper end into which bagels may be loaded, a lower dispensing area, and a transition portion through which bagels travel from the upper end to the lower dispensing area. The rotatable bin is preferably supported on a fixed base. The bin preferably includes a bottom wall having a plurality of openings therein to permit crumbs, seeds, and other particulate materials to fall into a receptacle supported by the base.

Abstract: A flat elongated substrate having a bead of a gas and/or moisture pervious adhesive having a desiccant is moved along a predetermined linear path between spaced upper wheels aligned with spaced lower wheels. The upper wheels have a peripheral groove to shape the bead as the substrate moves between the upper and lower wheels. The lower wheels each have a U shape peripheral groove with the base of the U of the downstream wheels being narrower than the base of the U of the upstream wheels and the depth of the U of the downstream wheels being deeper than the depth of the U of the upstream wheels to provide a spacer stock having a base connected to a pair of spaced upright legs such that the base connected to the legs have a generally U shape configuration and a shaped bead on the surface of the base between the legs. The spacer stock may be bent to form a spacer frame to separate outer sheets of an insulating glazing unit.

Abstract: A method is disclosed to deposit aluminum coatings on high temperature superalloys for corrosion, oxidation, and erosion protection using low temperature chemical vapor deposition and an organometallic halide precursor, specifically an aluminum alkyl halide. The process is adapted to protective coatings for turbine parts having internal passages. Due to the lower temperatures used during chemical vapor deposition, a broad range of substrate materials can be utilized. The precursor vapors clean the substrate surfaces by removing native oxides while simultaneously depositing aluminum.

The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75.

Abstract: An improved high-speed sense amplifier is disclosed for use in programmable logic devices (PLDs) and complex PLDs. The sense amplifier includes a transresistance amplifier portion that provides a voltage potential to a first node of a memory array, which defines a read product term line. The current drawn by the memory array will cause the output of the amplifier to change states once a predetermined current level is reached, the predetermined trip point indicating that at least one memory cell is conducting. The amplifier includes an n-channel MOS transistor having its drain connected between a second node of the memory array, and its source to ground. The gate of the n-channel transistor is connected to the read product line. The n-channel limits current through the memory array by raising the potential at the second node, thus reducing the voltage drop across the memory array.

Abstract: The present invention relates to a collection of ultra-thin bags and a collection of bags per se wherein said bags are made by providing two separated thermoplastic films; forming transversely across each separated film, lines of weakness extending from one edge of each film to the other, with each line spaced from the next a bag length distance apart; bringing the films together in face-to-face relationship with the lines of weakness across one film in registration with those of the other films; sealing the films transversely along lines parallel with and immediately adjacent to the lines of weakness; slit-sealing the film layers at one or more bag width intervals to complete individual but interconnected bag structures; and collecting each strip of interconnected bags into a volumetrically efficient form.

Abstract: The forward movement of a pipe-laying vessel when laying pipe offshore is controlled to maintain the position of the pipe as laid on the sea bed as close as possible to the desired track. The position of the touch down point on the sea bed of the pipeline suspended from the vessel is measured at periodic intervals by driving a survey vessel fitted with an echo location device along the already laid line. The measured position of a touch down point is compared with the desired track and any deviation is computed. Further movements of the pipe-laying vessel are adapted to minimize this deviation.

Abstract: An over-voltage protection apparatus includes an over-voltage detector measuring the voltage between each energized conductor and a neutral or ground line associated therewith series connected between an A.C. power source and a utilization device and an over-current protection device, such as a circuit breaker, to disconnect the conductors from the energy source in the event the voltage on any one of the energized lines exceeds a predetermined threshold voltage. Suitable over-voltage detectors consist of any device which is non-conductive for all input voltages less than a threshold voltage and are conductive after the input voltage has exceeded the threshold voltage.The over-voltage protection apparatus described is applied to A.C. power circuits having at least one phase and at least two wires. Use of the apparatus to also provide protection in the event of an open neutral line condition, when unequal loads are present between at least two energized conductors and the neutral line is also described.
