Abstract: ABSTRACT OF THE DISCLOSURE         A shroud apparatus for the continuous casting of steel comprising a fused silica or like refractory oxide nozzle having the outer surface thereof which is normally contacted by the layer of fused slag on the surface of the molten metal in the continuous casting mold when the nozzle is in normal operating position enclosed by a ring or sleeve formed of a slag resistant material, such as silicon nitride, boron nitride or zirconium diboride.  In one embodiment the nozzle has a ring member slidable axially along the length thereof with the ring floating in the molten metal and having one end immersed in the molten metal and the other end extending above the slag layer.  In another embodiment the nozzle has a protective ring member formed of the slag-resistant material mounted fixedly on the outer surface of the nozzle with the ring being of such length and positioned axially on the nozzle so that only the protective ring will be contacted by the slag layer during the continuous casting operation.          The method of continuous casting using such a shroud apparatus greatly increases the continuity and efficacy of the con-tinuous casting operation and improves the quality of the continuous casting.

Abstract: ABSTRACT         A key-operated actuator includes a frame, an elongated bolt having a driving connection to the device to be actuated, a tumbler mechanism which enables bolt rotation only when a key having proper configuration is inserted.  A frangible portion on the key axially displaces a non-rotatable sleeve which carries an anvil that breaks off the endmost frangible portion of the key.  The driving connection between the bolt and the device to be actuated is at all times maintained, and the bolt is restricted to angular movement of a predetermined magnitude, there also being anti-backup means to ensure full bolt movement in both directions.  A control disc is secured to the bolt and provides a portion of the anti-backup means, provides a portion of angular movement limiting means, provides an abutment that prevents bolt rotation when the last frangible portion has been broken off, and provides control for a further actuator that operates a further device.

Abstract: ABSTRACT OF THE DISCLOSURE    A control system is disclosed for a hydrostatic transmission of the type including a prime mover driven variable  displacement pump, the displacement of which is controlled by a pair of strokers (28, 30).  Flow of pressurized control fluid from the charge pump to one of the strokers, and from the other stroker to tank, is controlled by a main control valve (34).  The con-trol system in cludes an auxiliary control valve (44) defining passages (98, 100, 102) communicating between the lines connecting the main control valve and the strokers.  The auxiliary control valve includes an on-off, electro-hydraulic valve (46) which prevents flow through the auxiliary valve in response to an electrical signal in one condition, and permits flow in response to an electrical signal in another con-dition.  The electrical signals to the electro-hydraulic valve are generated by control logic (52) which alter-nates the electric signal between the one condition and the other condition at a duty cycle which varies pro-portional to the amount of pump destoke needed to pre-vent stalling of the prime mover.

Abstract: ABSTRACT OF THE DISCLOSURE . . _ . The specification describes a method of refuse collection as well as a transfer station used in conjunction with the method. The method generally involves subdividing an area in which refuse is to be collected into a plurality of service areas and providing each service area with a transfer station, collecting refuse in each service area using relatively low capacity collection vehicles which transport collected refuse to the transfer station of the service area whereat the collection vehicles discharge into transfer containers and emptying on a routine basis the contents of the transfer containers into relatively large transportation vehicles which transport the so collected refuse to an ultimate disposal site. The transfer station containers are such that they can readily receive the contents of the collection vehicles and readily discharge their contents into transportation vehicles.
