Abstract: ABSTRACT OF THE DISCLOSURE           An improved inflammable liquid safety tank compris-ing a double walled tank body with the tank walls being inter-connected by support plates.  An intermediate container is formed by the inner wall structure of the tank and is adapted to hold inflammable liquid.  A pressurized gas bottle is threadably mounted to a sleeve secured to and extending into the intermediate container.  The pressurized gas bottle is selectively connected to the intermediate container to pres-surize liquid held in the intermediate container.  The pres-surized gas bottle also communicates with the tank to pres-surize a foam, nonflammable fluid, or cleaning agent placed in the chamber or outer compartment defined by the outer wall structure of the intermediate container and the inner wall structure of the tank body so that the foam, fluid  or agent will be expelled from the tank if the tank wall is accident-ally punctured.  The outer compartment is preferably pressur-ized at a lower pressure than the intermediate container.  A conduit is connected to an inlet/discharge fitting and extends into the intermediate container adjacent the floor of the in-termediate container and below the level of liquid placed in the intermediate container.  A flexible hose with an adjust-able nozzle is mounted to the tank body for selective communi-cation with either the outer compartment or the intermediate container so that the material contained within either of the containers can be selectively discharged from the nozzle.

Abstract: ABSTRACT OF THE DISCLOSURE        A multi-channel, sequentially timed fuel injection system for an internal combustion spark ignited engine employs a solenoid actuated injector valve for each cylinder controlled by the outputs of separate variable width pulse generators.          The pulse generators each employ a resistance-capacitance discharge timing circuit and a single thermistor, common to all the generators, sensitive to engine temperature is connected to the RC circuits of the generators in a first circuit con-figuration during starting of the engine which provides a wide range of fuel delivery rates for starting and in a second cir-cuit configuration during normal operation in which the various RC circuits are isolated from one another so that interaction. of the variable width pulse generators does not occur as a result of the common thermistor connection during normal engine operation.

Abstract: Abstract of the Disclosure In a system for combining foreground video images with background video images, using the so-called "blue-screen" (or special background color) technique, a comprehensive control system is provided which accommodates a broader range of fore-ground objects, permits the careful coordination of control of the blue of the foreground with the level of the background signals, and also permits precise shadow control in accordance with the artistic requirements of the scene to be produced.          To properly control the level of the blue from the foreground and to properly distinguish between situations where the video signal arises from solid or partially transparent actual fore-ground objects and where it originates from the blue screen, various electrical adjustments are provided for accommodating different types of foreground objects.  One of the adjustments for controlling the blue foreground has three terms, one limiting the level of blue to the amount of green present in the signal, the second permitting an increase in the blue signal in accordance with a function of the positive value of green minus red, and a third term permitting increase of the amount of blue signal in accordance with a function of the positive value of red minus green present in the signal.  As will be described in greater detail below, these electronic circuits will handle the more difficult color situations involving, for example, blue eyes which present n difficult problem because of the similarity to the blue background screen; and purple objects which include high red and blue content but little green.  The background control signal may also be switched to three different types of control depending on the type of foreground which is being reproduced and included in the composite scene.  If desired, the background control signal switch may be mechanically coupled to the switch which limits the blue of the foreground.  As in the case of the control of foreground blue, the background control signal may have several terms.  In addition to the color terms which may be included in the background control signal, electronic circuitry is provided for both accommodating variations in brightness of the "blue screen" background, and also to control desired shadow effects, from completely eliminating shadows to intensifying them, with the additional capability of providing shadow effects.          Special switches are also being provided to switch from composite foreground and background video signal generation to (1) fore-ground only with background blacked out, (2) foreground complete with blue screen signals (3) background only, and (4) background only with foreground blacked out.  These switches permit the achievement of various special effects.

Granted: 1980-07-08
Abstract: ABSTRACT OF THE DISCLOSURE           This loss-of-vacuum detecting means for a vacuum circuit breaker utilizes input information derived from the current transformers of the overcurrent-sensing means typically present in medium voltage switchgear.  In this overcurrent-sensing means, the current transformer secondaries for the respective phases of the switch-gear are connected in parallel with each other across a shorting conductor; and in series with each secondary is hhe operating coil of an overcurrent relay.  Connected in the shorting conductor is an "a" switch that is closed when the vacuum circuit breaker is closed and is opened when the circuit breaker is opened.  Rectifying means is connected across said switch for developing a d.c. voltage when said switch is opened and one or more of said secondary windings is energized.  Time-delay relay means is arranged to be energized by said d.c. voltage and is operable when the voltage thereacross exceeds a predetermined level for a predetermined minimum period following opening of said switch.  Operation of said relay means is indicative of a loss of vacuum in one of the vacuum interrupters of the vacuum circuit breaker.

Abstract: HAROLD P. DAHLGREN          INK METERING APPARATUS             ABSTRACT        Ink metering apparatus comprising a resilient surfaced roller urged into pressure indented relation with a printing plate; a source of ink positioned to apply an excess of ink to the surface of the roller which has applied ink to the printing plate; and a resilient metering member having a hard, smooth, polished, highly developed, flexible edge resiliently urged in a direction generally radial of the roller and rigidly supported in a direction generally tangent to the roller surface for forming a film of controlled thickness on the surface of the resilient roller.  The flexible polished edge on the metering member is positioned in pressure relation with the resilient roller surface such that ink carried by the resilient roller surface impinges against a metering surface on the metering member adjacent the polished edge.  The flexible polished edge is resiliently urged into pressure indented relation with the resilient roller surface by a force of sufficient magni-tude to deform the flexible polished edge and the resilient roller surface such that the edge and the roller surface complement each other and cooperate to form an orifice which is self-adjusting to imperfections of the metering member and the resilient roller surface.  The metering surface on the metering member, against which ink impinges, is oriented such that hydrokinetic forces exerted by the ink on the metering member do not significantly alter the ink film when the surface speed of the resilient roller surface is changed.  The metering member is positioned such that the angle of departure between the metering member and the surface of the roller which has passed the polished edge is sufficient to cause separation of the ink from the metering member to prevent trailing of ink along the surface of the metering member.

Abstract: ABSTRACT OF THE DISCLOSURE        The determination of a "composite" parameter of the formation water in formations surrounding a borehole, for example the composite conductivity of the formation water, is used in the disclosure to obtain a relatively accurate determination of formation characteristics, such as water saturation.  The determined values are meaninful even in shaly regions of the formations.  The disclosed technique determines a composite water parameter, for example a composite water conductivity, which represents the conductivity of the bulk water in the formations, including both free water and bound water.  Bound water trapped in shales is accounted for in this determination so the shales can be considered as having a porosity.  Having determined the composite water conductivity, water saturation can be directly obtained using relatively straigthforward relationships which do not require estimates of the volume of shale in the formations.  Shale effects are accounted for by the different conductivities (or other parameter such as caputre cross sections) of the formation water constituents (free and bound) which make up the total water.

Abstract: ABSTRACT OF THE DISCLOSURE         A paper machine press arrangement for receiving a paper web from a forming wire and carrying the web through at least two non-suction press nips and, for example, a dryer section.  A first press nip is defined by a first grooved roll and a first controlled crown grooved roll.  A second press nip is defined by a relatively large diameter plane press roll and a second grooved roll.  In cer-tain embodiments, a third non-suction press nip is included and is defined by the large diameter press roll and a second controlled crown grooved roll.  A first felt wraps a suction pickup roll pos-itioned in working relation to the forming wire and picks up the web on the underside of the felt and carries the web through at least two non-suction press nips.  The second felt contacts the web prior to the first press nip and supports the web through the first press nip and is then guided downwardly away from the subse-quent press nips so that any broke may be dumped without shutting down the machine or accumulating broke.  The web is carried away from the second felt on the underside of the first felt with the aid of a suction transfer roll and is carried to the second non-suction press nip.  The first felt is guided away from the web after the second press nip back to the forming wire.  The web ad-heres to the outer surface of the plain press roll and is carried therefrom to a dryer or to the third non-suction press nip whereat a third felt contacts the web to guide the web through that work station.  The third felt is then guided away from the web, while the web is appropriately directed for further processing, such as to a dryer section.
