Abstract: ABSTRACT       Locking device locking the suspension nut of a driven shaft from rotation relative to the shaft, upon reversal in the direction of rotation of the shaft or such vibration as would loosen an ordinary nut. The locking device is particularly adapted for cantilevered shaft vertical pumps in which the shaft and pump impeller on the end of the shaft are susceptible to vibration. The locking device includes a pump coupling including a motor shaft coupling part and a pump shaft coupling part detachably secured to the motor shaft coupling part. A nut part having a cylindrical periphery is threaded on the pump shaft and recessed within the pump shaft coupling part, to suspend the shaft from the pump shaft coupling part. The full weight of the pump shaft, coupling and impeller, including the hydraulic thrust, is borne by the threaded connection between the pump shaft and the coupling nut. The coupling nut is tightened by a spanner wrench having projections fitting into drilled holes in the coupling nut. The pump shaft coupling part has a cylindrical inner periphery and an odd number of half holes opening to the periphery thereof. The nut has an even number of half holes opening to its periphery and so arranged that an aligned number of half holes may be formed by 1/72 of a revolution of one part relative to the other. A locking pin fits in the aligned holes and is of sufficient diameter to take the full torque load on the pump shaft and serves as a locking pin rather than a shear pin. The locking pin has a threaded hole in one end and can be removed by the insertion of a puller bolt in the threaded hole.

Abstract: ABSTRACT OF THE DISCLOSURE             A coincidence ink jet principle is disclosed wherein each ink jet has two inlet passages communicated to an outlet orifice.  Each inlet passage is communicated to a respective transducer chamber.  The fluid displacement and fluid velocity effected by a pressure pulse generated by each transducer chamber in a respective inlet passage is insufficient to express a droplet from the orifice.  However, the combined fluid dis-placement and fluid velocity, which is the result of the pressure pulses generated by the transducers being coincident at the orifice, will result in a droplet being expressed from the orifice.          In one system disclosed utilizing the above described principle, each inlet passage of a jet is communicated to a respective transducer and each transducer is connected to a respective electronic driver.  In this system, the number of electronic drivers and transducer chambers are substantially less than the number of ink jets.  These transducer chambers are time shared for expressing an ink droplet.  Actuation of the two transducer chambers communicated to a particular jet, in such a manner that the pressure pulses generated by the respective transducers co-incide at the orifice, will effect expression of a droplet there-from.  In another system disclosed utilizing the above described principle, a master transducer chamber is communicated to a sep-arate respective droplet expression transducer chamber and each droplet expression transducer chamber is connected to a respective electronic driver.  In this system, the master transducer chamber is actuated to create at each orifice a pressure pulse which is below the threshold pressure pulse for expressing an ink droplet therefrom.  Actuation of any of the droplet expression transducer chambers to generate a pressure pulse which coincides at a partic-ular orifice with the pressure pulse generated by the master transducer, will bring the resultant pressure pulse at the orifice above threshold to effect expression of the droplet from a partic-ular orifice.
