  • Patent number: 4386961
    Abstract: A heterologous ink composition for use in an ink jet apparatus features two miscibly incompatible components made compatible by the use of a common solvent having misability for both aqueously and non-aqueously miscible components. The heterologous ink composition derives its print quality characteristic from the non-aqueously miscible component and its good jetability and samll dot size from its aqueously miscible component.

  • Patent number: 4380529
    Abstract: The invention is for a fixed bed reactor with two phase gas and liquid flow. The reactor has at least one auxiliary bed of solid particles disposed above the main bed of solid particles. The auxiliary bed has separate liquid and gas bypasses comprised of hollow tubing extending through the auxiliary bed to a distributor tray. A liquid layer on the tray provides a liquid seal above the liquid bypasses, thereby preventing gas from bypassing along with the liquid. This feed arrangement allows for a low pressure drop bypassing of the auxiliary bed, when the auxiliary bed becomes fouled and clogged. The invention is also applicable to other apparatuses which use a flow arrangement similar to fixed bed reactors, but which do not necessarily utilize a chemical reaction. One example of such apparatus is a packed absorption tower having co-current downflow of gas and liquid.

  • Patent number: 4377445
    Abstract: Electrochemical systems having a plurality of cells which are hydraulically and electrically connected in series develop shunt currents in the electrolyte of adjacent cells. The shunt currents are reduced or eliminated by the placing of an electrical bypass across two adjacent intercell conduits, and applying a protective current through the electrical bypass in a direction of the shunt currents and of a magnitude that can effectively reduce the shunt currents.

  • Patent number: 4365009
    Abstract: The invention features an electrochemical cell having two fluid-containing compartments separated by a non-selective microporous membrane. Select ions which would normally pass through the membrane under the influence of an ionic field, are prevented from passing through the membrane by a polyelectrolyte which has migrated through the compartment fluid to the membrane. The polyelectrolyte acts as an ionic barrier to the passage of select ions, thus effectively increasing the ion-selective capability of the membrane and, hence, the coulombic efficiency of the electro-chemical cell.

  • Patent number: 4364054
    Abstract: A method and apparatus for fluid jet printing features a triode structured charge injection system. The ink jet system is not dependent upon the conductivity of the ink fluid to form and target the ink fluid. Two electrodes are in contact with the ink liquid and they are submerged in the fluid. One electrode is an emitter and serves to field emit charge into the liquid in response to a voltage between it and the other electrode. Depending upon the electrical mobility of the ink fluid, the injected charge will be trapped in the liquid. The liquid is then forced from an orifice and can be made to undergo break-up into droplets similar to inductively charged inks. The paper or target upon which the droplets impinge functions as a third electrode, returning the charge and completing the circuit. The ink may also be propelled as a charged column, which column can be directed by an extraneous electrical field for targeting upon the printing paper.

  • Patent number: 4362590
    Abstract: A light-weight, high-strength composite pin for use in pin-jointed reciprocating mechanisms and a method of preparation thereof is provided. Basically, the pin has a tubular metal sleeve and an interior fiber-reinforced resin core. At least 50% of the fibers in the core are continuous fibers which are oriented at a predetermined specific angle of orientation ranging, in general, from 0.degree. to about .+-.25.degree.. Indeed, in a preferred embodiment of the present invention, the fibers are cross-plied at an angle of orientation of from about 5.degree. to about 12.degree..

  • Patent number: 4361165
    Abstract: A breakaway pipeline coupling is described which comprises first and second pipe sections forming a fluid seal and designed to separate at a predetermined axial load. A plurality of piston and cylinder pressure compensating devices are arranged around the exterior of the pipe sections to hold them together until separation.Shear pins or shear studs passing between the pipeline sections will fail when the coupling is subjected to an external tensile force exceeding the predetermined maximum force. The pressure compensating devices apply a compression load on the coupling to counteract the tension load exerted by internal pressure in the pipeline. The pressure compensating devices included pistons movable axially within cylinders in response to pressure differentials, and porting or tubing for exposing one side of the piston to the internal pressure within the coupling.

  • Patent number: 4341291
    Abstract: A load control link for limiting maximum dynamic loads in and preventing overstressing of tension members by absorbing some of the energy which causes such loads. The load control link comprises a cylindrical housing, a metal sleeve mounted over a shaft within the housing and a cutting collar mounted at one end of the housing and around the sleeve. The inside radius of the cutting collar is slightly less than the outside radius of the sleeve, and is shaped as a cutting edge. The load control link is connected in series with a tension carrying member, with the end of the shaft which extends through the cutting sleeve connected at one end, and the opposite end of the housing connected at the other end. As the tension load on the control link increases, the shaft tends to be withdrawn from the housing causing metal to be cut from the surface of the sleeve by the cutting collar. The shaft remains stationary in the housing as long as the tension load remains lower than that required to cut metal.
