Abstract: Abstract A continuous casting process comprises feeding a mol-ten metal into a mould from a metal supply system through a metal feeding duct, effecting a stepwise withdrawal of a continuous strand or casting from the mould for a measured length and simultaneously feeding a molten metal into the latter, producing a superpressure on the forming skin of casting at the side of molten metal at intervals between the casting withdrawal cycles. On completion of the with-drawal cycle, the molten metal is fed from the metal supply system to an auxiliary vessel prefilled with an inert gas, whereupon a preset pressure is built up in the molten metal inside the auxiliary vessel and in the casting being form-ed. Next, the molten metal is moved to and fro between the auxiliary vessel and the metal feeding duct of the metal supply system. As the casting is withdrawn from the mould for a given length, the molten metal is concurrently fed into the mould from the auxiliary vessel and from the metal supply system.     There is also provided an apparatus for performing the above process.

Abstract: ABSTRACT In xerography, registration method and apparatus for a variable pitch copier. The invention has particular utility in achieving a speed and position match between a copy sheet and an image on a photoconductor as the copy sheet approaches an image transfer station. According to the invention the speed and position of both image and copy sheet are monitored and updated by a programmed microprocessor. Controlled accelerations and brakings of a copy sheet drive motor under microprocessor control first achieve registration and then maintain that registration as the image transfer occurs. The disclosed registration automatically adjusts for variable spacings between successive images about the periphery of the photoconductor to accommodate various image sizes.

Abstract: METHOD AND APPARATUS FOR SEQUENCE CONTROL OF        VERTICAL MOVEMENT OF SLURRIED PARTICULATES     ABSTRACT OF THE DISCLOSURE    A method and apparatus for sequence control of vertical movement of slurried particulates from a lower level to the upper levels, more particularly a vertical hoist system for movement of slurry from a subterranean mine area upward through an earthen or cased borehole to a surface station.          The vertical pump system includes series-connected pumps having variable speed capability to transport slurry par-ticulate from an underground sump upward to a surface surge tank or other repository.  The logic sequence system exer-cises control over valving sequence between the underground pumps and the vertical borehole in order to control slurry surges during start-up, shut-down and emergency dump opera-tions.  Thus, the pump input to the vertical conduit utili-zes energy dissipator units as selectively controlled by automated block and by-pass valves to control flow of fluids from the pumps upward through the vertical conduit.          Selective control of the dissipator units and valving enable critical start-up, shut-down and the emergency shut-down operations and this is effected by particular sequence control.

Abstract: A Coupling For Connecting Hose or Pipe Ends Abstract of the Disclosure A coupling for connecting hose or pipe ends has a sleeve portion and a cylindric insert portion, each to be secured to one of the ends to be connected.  The insert portion, when  "plugged" in the sleeve portion, sealingly engages same to provide the coupling.  The invention couples the two parts to prevent axial displacement of same.  It utilizes a locking lever pivotable about a transverse axis and having a locking bolt at a location between the pivot and the free end of the lever.  The pivot of the lever is mounted on a transverse cross-piece extending between free ends of the arms of a U-shaped frame surrounding the coupling.  The base of the "U" has an upwardly protruding second bolt.  The arms of the "U" are each curved outwardly such that in one position, the curved section releases the halves of the coupling for becoming disconnected, while in the locked state, a section of the curved arms engages the sleeve and the insert portion at suitable recesses, to interlock same together with both bolts as referred to above.  The advance in the art is in structural simplicity and ease of operation as a single lever, when locked, causes, in the disclosed embodiment, three additional locking places to become effective.

Abstract: TRUCK LOCKING DEVICE              Abstract of the Disclosure A device for locking a vehicle to a loading dock during a loading operation.  The device includes a frame mounted on the front surface of the dock beneath a pit which houses an adjustable dockboard.  A slide assembly is mounted for vertical movement on the frame, and the slide assembly includes a locking member adapted to engage an abutment on the vehicle, as the slide assembly is elevated.  To raise and lower the slide assembly, a motor is mounted on the slide assembly and drives a gear that engages a rack carried by the frame.  The rack is spring biased to an upper position, and on operation of the motor in one direction, the slide assembly is raised to bring the locking member into engagement with the abutment on the vehicle.  Continued operation of the motor will thenmove the rack downwardly relative to the gear and slide assembly, and downward movement of the rack will activate a switch to cut off power to the motor.          After the loading operation is completed the motor is driven in the opposite direction to lower the locking member to its storage position.  The movement of the slide assembly and locking member can be tied into the operation of the lip of the dockboard in which the motor will automatically be operated to move the locking member upwardly toward the locking position when the lip is raised from its pendant position, and the motor will be operated in the reverse direction when the loading operation is completed and the lip is returned to its pendant position.
