Abstract: ABSTRACT OF THE DISCLOSURE           A method of manufacturing a covered roller or idler having a cylindrical metal core and a tubular ultra high molecu-lar weight polyethylene cover.  According to this method, the cover which has a slightly smaller inside diameter than the outside diameter of the core, is heated and subsequently mecha-nically expanded to increase its inner diameter.  The so heated, expanded cover is then slipped over the core and allowed to cool to provide a tight shrink fit.

Abstract: ABSTRACT OF THE DISCLOSURE         A latch for anchoring well tools in landing receptacles such as nipples or side pocket mandrels in well flow conductors, the receptacles having a locking recess providing a lock shoulder which may be fully annular or only 180 degrees in extent.  The latch includes a housing having windows in the wall thereof and a locking lug in each window movable both radially and axially of the housing to engage and disengage the receptacle lock shoulder.  A spring biases the lugs downwardly.  A lock sleeve slidable on a central core normally holds the lugs against inward movement from expanded locking position and has a recess in its outer surface which allows the lugs to move up and retract thereinto to pass obstructions in a well, the spring returning the lugs to expanded position as soon as such obstruction has been passed.  Shearing a pin permits the lock sleeve to be lifted to a position to allow the lugs to retract freely.  In a modified embodiment of the invention, the device includes a core which is slidable and which is operationally associated with the well tool supported by the device and performs a function therein.

Abstract: Abstract Fundamental construction of a written procedure (a written explanation, a written composition example, a written commentary, a written analysis, a written ledger) and method for processing thereof for effecting smooth replection of content of the procedure, lightening of burdon and efficacious-ness, relating to patents.       Minute making-out and examination of related matters are frequently needed in the procedure relating to patents and the contents or the formality thereof is difficult to understand.  In order to solve a varisty of subjects derived from the above, a construction of the written procedure is attempted in which a column, a page and a written document in the relating matter are mutually and intimately checked correspondingly and also standardized.  Especially, the written analysis and the written ledgar are constructed so that relative advantage therebetween obtained in grading up process by unifying and corresponding the two written documents in order to solve a subject due to separation in the speciality between the technique and the patent.   Embodiments are shown in which key subject are solved between patent administration and technique administration.       Further, means for yielding an effective multiplication by activating the features of the written documents are shown in the method for processing and bases to be applicable not only to the procedure for application but also to be general procedure relating to patent are provided.

Abstract: ABSTRACT OF DISCLOSURE This invention relates to a trench shoring assembly which includes a pair of spaced-apart side walls for vertical disposition within a trench. Spreader pipes and spreader collars interconnect the side walls and allow limited pivotal movement between the side walls.  Each side wall includes outer and inner metal plates connected to a horizontally extending hollow top beam which extends longitudinally along the top of the side wall, two intermediate beams parallel the hollow metal beam and a bottom beam.  A hardwood insert is disposed within the top beam to prevent the collapse of the hollow metal beam. A number of hollow beams extend perpendicularly to the horizontal beams and ribbed members extend perpendicularly to the horizontal beams.  The side walls of the assembly have a tapered bottom portion which defines a triangularly shaped pointed lower extremity extending between the ends of the bottom portion. A metallic bar is disposed at the pointed lower extremity and extends between the ends of the bottom portion and protects the bottom of the side wall against abrasion.  A U-shaped member is welded to the main frame, and, in turn, a spreader collar is welded to the U-shaped member so that a force applied to the spreader collar is transferred directly to the main frame.  Each spreader pipe spaces the side walls apart between two spreader collars to which the spreader pipe is attached by spreader pins.  Lifting rings are slidably attached to the spreader pipes for lifting the assembly.  A plurality of flanges extend from a spreader pipe and are connected by locking pins to mating flanges which extend from another spreader pipe of another vertically stacked trench shoring assembly.

Abstract: ABSTRACT OF THE DISCLOSURE A serious problem in size presses has been the splashing of the sizing or coating agent.  The disadvantages caused by this have been further accentuated when the speeds of size presses have increased.  Splashing problems are especially significant in on-machine size presses.  In order to avoid these problems, a size press is disclosed comprising one or more coating nips.  The web to be treated is led through the nips in a generally upwards direction.  Coating agent supply apparatus is associated with the size press by means of which coating pools are formed in the nip entrance between the coating roll and the web entering the nip.          In the nip entrance at least one filling piece is associated with the coating supply apparatus and placed in the coating pool when in the operative position.  The filling pieces are made of penetrable porous or perforated material.  The filling pieces extend across the whole width of the web and suppress the coating pools and prevent or at least substantially decrease the splashing of coating agent.
