Abstract: ELECTRICAL PLUG OF DEAD FRONT DESIGN                      Abstract The present invention is a quickly assembled electrical plug of dead front design.  An integrally molded hinge connects the dead front terminal block to a first housing portion and a similar hinge connects the  second housing portion to the first.  Also connected by molded hinges to this composite assembly are two cord gripping strain relief fingers which are held in firm contact with the cord after assembly by a cover or shell.  The line terminals are designed in connection with the terminal block so that their wiring screws all face in the same direction and may be connected to the cord conductors during assembly without rotation of the plug.  After the cover shell is screwed onto the device, a ratchet assembly molded into one of the housing portions and cooperating with elements contained in the shell prevents inadvertant loosening of the shell.

Abstract: ABSTRACT         A standard printing cylinder is supported by a mandrel assembly in a printing machine having bearings, the cylinder having end heads at either end provided with circular bores and being demountable on the mandrel assembly.  The assembly comprises a tube receivable within the cylinder and journals joined to opposing ends of the tube and extending axially therefrom for insertion in the machine bearings.  Each journal has an expansible metal sleeve pinned thereon whose normal diameter is such that the sleeve fits into a respective end head bore of the cylinder.  The sleeve surrounds an annular hydraulic chamber formed on the journal, which chamber communicates with an axially-extending main internal duct filled with hydraulic fluid and having an inlet section in line therewith whose mouth opens into the free end of the journal.          The journal has a leading section which is shrunk fit onto an end of the tube and an intermediate section which is surrounded by the sleeve to define the annular hydraulic chamber.  The intermediate section has grooves on either side of the chamber in which "o" rings are received to effect a seal preventing leakage of fluid when the sleeve is expanded.  A piston is slidable in the inlet section and has a piston screw which is accessible through the mouth.  The screw when turned in advances the piston to produce hydraulic pressure which is transmitted through the chamber to the sleeve to cause expansion thereof whereby the sleeve grips the end head to lock the cylinder to the mandrel.

Abstract: ABSTRACT    A cassette for a scratch strain recorder has a rotatable supply bobbin geared directly to a rotatable take-up bobbin so that rotation of the take-up bobbin will be equal in amount but opposite in direction to that of the supply bobbin.  The recording tape is formed of a roll of flat resilient material which has one end attached to the supply bobbin and which, in the unused condition, is almost totally wound around the supply bobbin except for the other end which is attached to the take-up bobbin.  The tape is driven by a capstan and pinch roller, the capstan being arranged for driving connection to a drive shaft of the strain recorder itself.  Because of its inherent resilience the coil tries to straighten, i.e. unwind, and this assists rotation of the two bobbins when the capstan is operated and the direct gear inter-connection causes an equalization of the spring forces between the two bobbins as the cassette progresses from an unused condition to a nearly completely used condition.

Abstract: ABSTRACT OF THE DISCLOSURE A disc brake is actuated through a mechanical linkage com-prising a power screw (54) which is rotatably mounted within the housing (22) and a piston or power nut (38) which is threadedly engaged with the power screw (54) and which also is engaged with the friction element (32).  An annular thrust collar (70) is installed within the housing (22) and defines a thrust receiving surface (73) which faces a surface (62) on the power screw (54). Brake reaction forces are transmitted to the wall of the housing (22) without loading the bolts (86) in tension by way of the surfaces (62, 73) of the thrust collar (70), the surface (108) and the retaining ring (66).  A take-up ring (84) made of a de-formable material is carried in the groove (82) of the thrust collar (70) so that, when a brake is manufactured, the thrust collar (70) is first installed in the bore and the retaining ring (66) is then installed in the groove (64).  When the brake is first applied, the reaction forces drive the collar (70) into the position illustrated in the drawings, thereby deforming the take-up ring (84) to pass under the retaining ring 66.  The take-up ring (84) thereafter assumes its original shape to engage the retaining ring (66) to hold the thrust collar (70) in place.  An alternate embodiment discloses an equivalent hydraulic actuator, in which the power screw is replaced by a hydraulic coupling.

Abstract: PAPERMAKERS FABRIC OF NONWOVEN LAYERS IN        A LAMINATED CONSTRUCTION                Abstract A papermakers fabric made up of a plurality of impervious nonwoven sheets joined together in a laminated arrangement to define the fabric or belt.          Defined throughout the fabric are a series of drainage apertures which are created in the fabric by conven-tional techniques, such as laser drilling.  The size and distribution of the apertures can be varied to provide a given permeability.  Small surface apertures are provided to prevent loss of fiber through the fabric.  Each of the layers of the papermakers fabric serves a particular purpose.  For example, one or more of the layers may be made of an abrasion resistant material.  Other layers may be made of materials exhibiting other desirable characteristics such as resistance to heat, acid, flame and static charge, to name a few.  Yarns to provide added strength may be placed between the layers or incorporated into one or more of them.  A fabric according to the invention may be made self-cleaning by the incorporation of a detergent or other material within or between the layers of the fabric.  Operation of the fabric on the papermachine will cause the release of the detergent and will accomplish the cleaning.  Materials such as traditional bolt fabric may be incorporated with the laminated fabric in order to obtain the advantages of each.  Embossed surface layers can be provided to aid in the control of the belt on the papermachine.

Abstract: TITLE: LUBRICATOR VALVE APPARATUS             ABSTRACT OF THE DISCLOSURE    A lubricator valve assembly comprises a reciprocably rotatable ball valve which is operated between open and closed positions solely through the selective application of control pressures and/or tubing pressure above the valve to a double acting sleeve type actuating piston.  One end of the actuating piston has a valving piston formed thereon which cooperates with seal bore in the housing to effect the opening or closing of a bypass fluid passage extending from a region below the ball valve to a region above the ball valve.  Such valving piston also functions as part of a lost motion connection between the actuating sleeve piston and a reciprocable actuator for rotating the ball valve.  In opening the ball valve, the valving piston first moves upwardly to establish a fluid bypass around the closed ball valve and then establishes contact with the actuator to rotate the ball valve to an open position.  The same fluid bypass may be utilized to pump through fluid around the closed ball valve by applying fluid pressure above the ball valve.          Improved sealing elements for the ball valve are also provided.
