Title: Non-pulsating, non-throttling, vented pumping system for continuously dispensing product

Abstract: NON-PULSATING, NON-THROTTLING, VENTED PUMPING SYSTEM FOR CONTINUOUSLY DISPENSING PRODUCT ABSTRACT OF THE DISCLOSURE A non-pulsating, non-throttling, vented pumping system is disclosed for continuously dispensing product from a container in a relatively non-pulsating stream or spray. The pumping system includes a pump for withdrawing product from a container and for pressurizing the product, a storage compartment for storing the product under pressure, an accumulator piston in the storage com-partment acting under bias to maintain the pressure on the product, an outlet passage opened and closed by the accumulator piston, and a restricted orifice at the outlet passage through which the pro-duct is dispensed as a stream or spray. The restricted orifice allows only a portion of the product pressurized by the pump to escape during the pressure stroke of the pump, and the remainder of the product is stored in the product storage compartment to be released for maintaining the spray or stream when the pressurizing pump is acting on its intake stroke. The accumulator piston shuts off the outlet passage when the pump is at rest in a manner such that the pump is non-throttling. The container is vented to the atmosphere through the pump. The pressurizing pump's actuator has a relatively short stroke and so can be pumped rapidly such that the stream or spray need not be maintained by the accumula-tor piston for a long time on a given intake stroke.

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed herein is a ring laser gyroscope having two oppositely traveling laser beams and is provided with mechanically dithered mirrors at its three or four reflection points.  Each mirror is mounted for movement in and out as the result of the expansion and contraction of stacks of piezoelectric elements associated with each mirror.  The mirrors are thus dithered, i. e. oscillated in and out, in phased relationship with one another so that the total length of the laser cavity is held at a fixed number of wave-lengths, but the laser beam translates back and forth across the surfaces of the mirrors.  By this technique, the undesired phenomenon of lock-in at low rotation rates of the gyroscope is avoided, without the need for special optical or magnetic structures in the path of the laser beam.

Granted: 1980-12-02
Abstract: Abstract of the Disclosure A process has been developed for the oxidation of organic substances, dissolved or dispersed in an aqueous system, with a gas containing molecular oxygen at elevated temperature and under elevated pressure chiefly to carbon dioxide and water, with subsequent phase separation of the reaction mixture into a gaseous phase substantially containing inert gas, carbon dioxide, steam and organic constituents and a liquid phase substantially containing water, characterized in that the pressure is adjusted, at the given temperature, so that by evaporation of water from the aqueous system, more steam than the exotherm-icity of the oxidation reaction gives rise to,goes into the gaseous phase, which is fed to a heat exchanger in which the amount of heat required to maintain the oxidation temperature is completely or partially transferred to a mixture of water and a gas containing molecular oxygen, which mixture flows in on the other side of the heat exchanger and is subsequently fed to the reactor.      A particular advantage of the process of the invention is that, in addition to the oxidation of organic substances, it is possible to fed inorganic constituents, after the oxidative degradation of the organic substances, to a re-use or recovery process.

Abstract: PATENT APPLICATION of George K. Farney and F. A. Feulner for METHOD AND APPARATUS FOR       REDUCING NOISE IN CROSSED-FIELD AMPLIFIERS     Abstract Noise in reentrant-stream crossed-field amplifiers is suspected of being generated by electrons re-entering the interaction region with large amplitude cycloidal motion near the slow-wave circuit.  Means to increase the electric field in a portion of the drift region preceding the circuit lowers the noise, presumably by collecting these electrons.          The field may be increased by decreasing the spacing bewteen cathode and drift electrode or by applying a bias voltage on an insulated electrode.     rbn2C9276                - 1 -                  76-44

Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for eliminating time base errors from a carrier-modulated information signal, such as a color video signal which is reproduced from a record medium.  A circuit including a vari-able oscillator generates a carrier signal of controllable fre-quency and phase.  An automatic frequency control circuit detects the time base frequency error in the carrier-modulated informa-tion signal and produces a frequency error signal proportional to the detected frequency error.  An automatic phase control circuit detects a time base phase error in the carrier-modulated informa-tion signal and produces a phase error signal proportional to the detected phase error.  A switching circuit selectively supplies either the frequency error signal or the phase error signal as a control signal to the variable oscillator so as to corresponding-ly control the frequency and phase of the generated carrier signal. in a manner to eliminate such frequency and phase errors, the frequency and phase error signals being supplied to the variable oscillator during selected mutually exclusive intervals.  A frequency converter is provided with the controlled carrier signal and with the information signal so as to convert the carrier of the information signal with the generated, controlled carrier such that the frequency-converted information signal has a carrier of substantially constant frequency and phase.

Abstract: ABSTRACT OF THE DISCLOSURE          A process for the preparation of agglomerates of aluminium oxide is disclosed.  The process comprises contacting a hydrous aluminium oxide gel with an organic liquid which is essentially immiscible with water.  The organic liquid is utilized in an amount such that the weight ratio of said liquid to water, as contained in the hydrous gel, lies within Region II of a plot of said ratio versus the pore volume of aluminium oxide obtained after being dried and calcined.  Subsequent to the gel being contacted with the organic liquid, the gel is subjected to agglomeration conditions.  Region II of the referenced plot is a region in which the slope of the curve plotting the ratio of organic liquid to water versus the pore volume, as discussed above, has a value equal to or greater than about 4Ø           (I)

Abstract: ABSTRACT OF THE DISCLOSURE:             This specification relates to a closure or door preferably for industrial buildings and is of the type in which the door leaf or sheet of flexible material is suspended over the opening by securing its upper edge and being opened or closed by raising or lowering its lower edge.  The raising and lowering is carried out by means of a pair of ropes or the like that are connected to a hoist member, each rope extending within a respective separate channel extending along a vertical side of the opening, each rope or the like being connected to the lower portion of the leaf through a protection means that prevents uncontrolled lowering.  This protection means, in response to a predetermined decrease in the load on the rope, is released to lock the lower portion of the leaf to the respective guide bar.  The protection means includes a spring biased rod that is movable relative to the leaf and is connected to the respective ropes, the rod being connected by links to locking mechanism having dogs that are pivoted in cross-wise arrangement on a common shaft.  The arrangement is such that under the action of the spring, the rod drives the links so as to cause outward movement of both ends of each dog and into engagement with the lateral flanges of the associated guide bar at any position of the lower portion of the leaf relative to the guide bars so as to lock the leaf against movement relative to the guide bars unless the tension in the ropes is of sufficient magnitude to override the action of the springs.
