Abstract: S P E C I F I C A T I O N     TITLE:  REFRACTORY COATING OF EDGE-DAM BLOCKS         FOR THE PURPOSE OF PREVENTING LONGI-TUDINAL BANDS OF SINKAGE IN THE PRO-DUCT OF A CONTINUOUS CASTING MACHINE            INVENTORS:  STANLEY W. PLATEK             S. JERRY DESAUTELS WOJTEK SZCZYPIORSKI     ABSTRACT OF THE DISCLOSURE           Continuous casting methods and apparatus are described wherein a defect in the cast surfaces consisting of longi-tudinal bands of sinkage, sometimes called "sinks", which are spaced relatively far inwardly from the edges of wide, relatively thin slab or strip,usually being spaced inwardly away from the edges by a distance of 3 to 7 times (sometimes up to 9 times) the thickness of the cast slab, is practically eliminated by means of a coating or covering of non-wettable refractory ceramic material of low heat conductivity applied to the inner faces of the edge-dam blocks for reducing heat flow out of the edges of the slab or strip being cast.    Numerous such blocks are strung onto a flexible metal band or cable to constitute each of the two edge dams which define the edges of the mold space.          Alternative methods for reducing heat flow from the edges of the slab or strip being cast are disclosed -- notably the breaking of thermal contact by means of jiggling by rocking individual edge-dam blocks back and forth; also the use of sintered edge-dam blocks, and the heating of the edge-dam blocks along the casting region.  One or more of these alternative methods may be used in conjunction with the coating of refractory material on the inner faces of the edge-dam blocks for further reducing or controlling the flow of heat out of the margins of the metal being cast into the edge-dam blocks.

Abstract: SPIN BLASTER     ABSTRACT OF THE DISCLOSURE           Apparatus for blast-cleaning the interior surface of a pipe includes a main housing that travels the length of the pipe, and rotatably supports a blast nozzle.  A nozzle support shaft journaled in bearings carried by the housing, rotates freely, reactively to the force exerted within the nozzle by a carrier fluid, which is forced through the nozzle under high pressure, thus causing the nozzle, and hence the nozzle support shaft, to rotate at high speed within the housing.          The carrier fluid is usually compressed air.  Since it is directed through a non-rotating conduit to the rotating support shaft, a gasket is interposed between the rotating and non-rotating components of the apparatus.  To prevent the carrier fluid and the abrasive media carried thereby from penetrating the shaft support bearings of the housing with obviously destructive effects, a gap is maintained between the housing and a junction housing in which the non-rotating conduit is mounted.  The almost inevitable leakage that does occur past the gasket is dispersed to the ambient atmosphere through the gap, before it can impinge upon the bearings in which the shaft is journaled.  The non-rotating conduit is threadedly advancable within the junction housing, so as to correspondingly, selectively adjust the extent to which the gasket is compressed, thereby permitting swift take-up for wear of the gasket without detracting from its capability for dispersing the abrasive media to ambient atmosphere when leakage does occur.          In each position to which the conduit is selectively adjusted, it can be locked, so as to preserve the selected, adjusted compression of the gasket.

Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a gate valve which is moved to  open  position  by  an  extendible  and  retractable, fluid-operated  actuator,  and which  is  moved  to  closed position, upon exhaust of operating fluid, by coil springs which urge follower parts reciprocable with a stem on the gate, and which extend from the valve body into a housing connected on  the valve body,  into  engagement with cam surfaces on the housing.  The cam surfaces are so arranged that the coil springs initially move the gate from open toward closed position with a relatively small force, and then move it into fully closed position with a force which is  sufficiently  larger  to  shear  a wire  line  or  other obstruction in the flowway of the valve body which would otherwise prevent closing of the gate.

Abstract: NON-UNIQUE NAMES FOR BROADCAST MESSAGES              Abstract of the Disclosure A data communication system described in one of the referenced co-pending patent applications, allows  communicating  processors  to  act  without reliance on a  common directory to adopt logical names  for  respective  locally  attached  entities (programs, data files, human operators, etc.), and to initiate sessions relative to remote entities by means  of  communications  directed  to  respective entity names (rather than addresses associated with the  physical  locations  of  respective  entities).          The  present  disclosure  concerns  a  method  for extending the name adoption process of the refer-ence to allow for adoption of names either on a unique basis (association of the name with one and only one entity) or a non-unique basis (association of one name to plural entities).  Names adopted on a  non-unique  basis  are  flagged  as  such  in  the adopting system  and name checking communications directed to such names are ignored by processors serving the respective entity (thereby allowing the checking  processors  to  adopt  the  respective non-unique name, using the existing procedure for adopting unique names, and thereby enabling proces-sors serving a group of entities to adopt a common name for directing network communications to the entire   group   concurrently).    The   disclosure describes specific communication applications made possible by this non-unique naming capability.

Abstract: ABSTRACT OF THE DISCLOSURE         An inductive load, more specifically a direct current motor, is fed by a direct current source through a semiconductor regulator which contains two parallel switching controllable semiconductor rectifier elements with identical conduction direction which in turn are in series with a respective one-half of a center tapped output autotransformer.  Parallel to the semiconductor regulator is an additional and identical semi-conductor regulator.  The center tap points of both semiconductor regulator auto transformers are connected with the terminals of a third output auto transformer which is similarly center tapped, whereby the center tap point of the third output auto transformer is connected to a terminal (+) of the inductive load. The control assembly is made in such a manner that it produces clock frequency signals with identical control levels for both semiconductor rectifier elements, however, these signals for the two parallel switching arrangements are electrically offset by 90 degrees.  In this way, it is possible to operate the motor in RPM ranges where a minimum of ripple current is obtainable.
