Title: Hydraulic device for controlling the perpendicularity  of boom members in mobile platforms
Inventor: JOHNSON LEONARD L
IPC: B66F11/04
Filed: 1977-06-27
Granted: 1980-09-16
Abstract: ABSTRACT OF THE INVENTION         In connection with a pair of articulated booms there is a leveling system consisting of a sprocket wheel at the base of the lower boom and a co-acting sprocket wheel at the free end of the upper boom with chains and rods interconnecting the two sprockets and constituting part of the leveling system maintain-ing the basket connected to the free end of the upper boom in a level condition.         The angular position of the sprocket wheel on the upper boom is calibrated so as to be in a direct relationship to the perpendicularity of the upper boom relative to the horizon, which in turn is related to chain movement at the upper boom.         A control valve associated with the upper boom is actuated by a cam on the chain so the valve is operated at what-ever preselected critical angle of perpendicularity of the upper boom is desired.  The control valve, in turn, has fluid connect-ions with power actuator means associated with each of the upper and lower booms to preclude further movement of either the upper or lower boom which would increase the perpendicularity of the upper boom beyond its critical predetermined amount.  Fluid con-nections are provided to the power actuator means associated with the upper and lower booms to permit either or both of the booms to be actuated in a direction decreasing the perpendicularity of the upper boom from its critical position whether the control valve has been operated or not.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a interchange termination apparatus for multi-function telecommunication devices, such as key telephones.          Telephone termination systems, particularly those associated with key telephones in a business office environment, have heretofore required a great deal of time and expense in connection with installation, maintenance, and line and function flexibility in providing changes in an alteration of service.  The present invention overcomes these problems by providing a module for a modular termination interchange system which has a one-piece panel supporting an array of contacts.  Patch cord connectors engage selected ones of these contacts from the front side of the panel as a means of selectively programming line selection and/or function.          A plurality of projections extend from the rear of the panel to support electrical connector units each having a plurality of contacts which are electrically connected to the contacts supported by the panel, the contacts of a connector unit connected to respective contacts of at least one row or rows with a particular electrical connector unit.  Complementary mating connector units are interengageable with the connector units supported by the panel projections and extend the electrical connections, via respective cables, to telephones at the distal ends of the cables.          The interchangeability of the electrical connectors permits complete freedom in associating telephones with telephone lines and signaling and switching functions without relocating a telephone instrument.

Abstract: PROCESSES FOR PRODUCING POSITIVE OR NEGATIVE DYE IMAGES  USING HIGH IODIDE SILVER HALIDE EMULSIONS     Abstract of the Disclosure Processes are disclosed for producing dye images employing photographic elements which comprise a support and coated thereon, at least one radiation-sensitive color-forming layer unit.  This layer unit includes a substan-tially uniform distribution of catalyst and a radiation-sensitive, high iodide silver halide emulsion.  A first method for producing dye images after imagewise exposure of the photographic element comprises the steps of imagewise poisoning the catalyst with iodide ion by developing the silver iodide containing silver halide emulsion and there-after employing the remaining unpoisoned catalyst to permit a redox reaction between a peroxide oxidizing agent and a dye-image-generating reducing agent.  In a preferred element the high iodide silver halide emulsion is comprised of multifaceted, radiation-receptive silver iodide crystals and silver chloride crystals forming epitaxial junctions with the silver iodide crystals.  A dye image of opposite sense can be produced using the preferred element by the steps of poison-ing the catalyst; selectively developing the silver chloride portion of the silver halide emulsion; and amplifying the resulting silver image using the peroxy redox amplification reaction.

Abstract: ENERGY CONSERVING AUTOMATIC LIGHT                      OUTPUT SYSTEM                   Abstract of the Disclosure An energy conserving lighting system is provided wherein a plurality of fluorescent lamps are powered by a poorly regulated voltage supply which provides a decreasing supply voltage with increasing arc current so as to generally match the volt-ampere characteristics of the lamps.  A transistor ballast and control circuit connected in the arc current path controls the arc current, and hence the light output, in accordance with the total ambient light, i.e., the light produced by the lamps together with whatever further light is produced by other sources such as daylight.  In another embodiment, a transistor ballast is utilized in combination with an inductive ballast.  The transistor ballast provides current control over a wide dynamic range up to a design current maximum at which maximum the transistor is saturated and the inductive ballast takes over the current limiting function. An operational amplifier is preferably connected in the base biassing circuit of the control transistor of the transistor ballast.  In an embodiment wherein two sets of lamps with separate inductive ballasts are provided, the arc currents for the two ballasts are scaled or matche to provide the desired light output.

Abstract: ADAPTIVE BRAKING MODULATOR VALVE  ABSTRACT OF THE DISCLOSURE          In a single fluid brake system a modulator valve communicates with a pressure source and provides for communication of pressurized fluid From a master cylinder or brake booster to a wheel assembly to effectuate braking of the latter.  An electronic control unit monitors the wheel speed of the wheel assembly and cooperates with the modulator valve to relieve braking pressure when a skidding condition is imminent. The modulator valve includes a first piston which forms a variable volume chamber in communication with the wheel assembly and a second piston which cooperates with the electronic control unit to provide for movement of the first piston during skidding.  When the first piston moves, the variable volume chamber is expanded to receive fluid from the wheel assembly thereby relieving braking pressure to avoid skidding of the wheel assembly.  Normally, the second piston includes opposite faces which are exposed to a reservoir; however, when the electronic control unit is activated upon imminent skidding, the second piston is exposed to pressurized fluid from the pressure source on one face to move the second piston and impart movement to the first piston.  A sleeve between the pistons forms a portion of a passage through thy modulator valve and limits the movement of the first piston in one direction.

Abstract: TITLE          A METHOD AND APPARATUS FOR CONTINUOUSLY CASTING MOLTEN METAL                   INVENTOR                 ROBERT THOMSON                    ABSTRACT          A method of continuously casting molten metal in a reciprocable  mould sealed to a vessel containing liquid metal by means of an extendible container, wherein a tube forming a passage from an orifice in the vessel to the mould is sealed at one end to the vessel, and at the other end dips into molten metal in an entry to the mould.  A meniscus of molten metal around the tube and in the mould is stabilized by adjusting the pressure of inert gas fed into the extendible container so that the rate of flow of metal from the vessel to the mould is controlled directly by the rate of extraction of the solidifying casting from the mould.  The problems related to controlling metal flow into the mould are substan-tially reduced.  This is of particular significance in continu-ous casting steel, permitting the casting rate to be indepen-dent of the size of the orifice in the vessel, and of the ferrostatic head above it.  Thus it is possible to use a larger orifice in the vessel, alleviating the problem of nozzle blockage, and to continuously cast aluminum killed steels where deoxidation by and alloying of aluminum is achieved in the vessel or during prior refining  stages of preparation of the molten metal.
