Abstract: Title Actuator For Friction Coupling Abstract of the Disclosure A friction coupling apparatus contains a plurality of fluid motor actuators circumferentially fixed about a relatively rotatable shaft.  Each of the actuators is positioned between a spaced pair of friction rotors fixed to the shaft for rotation therewith.  The actuators each contain an annular axially distensible elastomeric air tube, which upon pressurization operates to force pairs of friction members against the rotors for establishing frictional communication between the shaft and a relatively fixed support member.  In a preferred embodiment, the elastomeric air tube contains a pair of axially spaced apertures.          Each aperture defines a circumferential sealing edge by which one of a pair of air pistons is supported.          Each piston contains a circumferential groove which sealingly mates with one of the edges, the pistons positioned to bear directly against the friction members.

Abstract: ABSTRACT         The invention relates to a blind rivet having a shear portion that is accepted within aligned apertures in a workpiece.  The rivet has a pre-formed head at one end of the shear portion and a central aperture therethrough for the acceptance of a headed mandrel.  An incompletely polymerized thermoset resin portion of the rivet is disposed about the mandrel at the opposite end of the shear portion from the head thereon.  Tensioning of the mandrel effects compression of the incompletely polymerized portion which is softened due to the application of heat.  The mandrel forms a radially extending blind head that is interlocked with the shear portion of the rivet to draw the workpieces together and which, when fully polymerized, forms a permanent thermoset riveted connected.

Abstract: ABSTRACT         A video signal coding apparatus includes a motion detec-tor for detecting a motion contained in the video signal to deliver a motion vector and an inter-frame prediction coder for coding the video signal in response to the motion vector.  An intra-frame coder is also present in the apparatus for coding the video signal by using a spatial correlation of the video signal for refresh operation and a control circuit is provided for alternatively selecting the inter-frame prediction coder and the intra-frame coder to code the video signal.  Finally a motion compensation inhibiting circuit inhibits the operation of the motion detector for a predetermined period with respect to an area where the re-fresh operation has been completed.  The invention permits errors to be removed by the refresh operation which is an improvement over existing systems which employ motion compensation.

A new printing ink has been developed which is based on a polymeric binder, a solvent therefor and an adhesion promoting agent which is the reaction product of a titanium orthoester and either a monoalkyl phosphate or a dialkyl phosphate or a mixture thereof in such proportions that the molar ratio of titanium to phosphate expressed as Ti:P is from 4:1 to 1:2.
