Abstract: Abstract Thermotropic, wholly aromatic polythiolesters exhibit an anisotropic melt.  The polythiolesters may be prepared from monomers selected such that all or substantially all of the repeating groups are thiolester groups.  Alterna-tively, the monomers can be selected such that sufficient thiolester groups are present to impart processability to a normally non-tractable polyester.  Preparation of tpe poly-thiolesters is typically accomplished by melt polymerization of an esterified aromatic mercaptan compound, either alone or with other copolymerizable monomers.  The polythiolesters may be melt processed into fibers, films or other types of shaped articles.

Abstract: ASSEMBLING HOSE UNITS FOR APPLIANCES     Abstract of the Invention Method and apparatus for assembling a hose unit consisting of a given length of hose having end couplings inserted respectively in each of its ends. The given length is measured and cut off, being inserted freely, longitudinallyin a rigid tube without endwise restraint. The couplings are inserted simultaneously, the thrust applied being balanced as well as sufficient to compress the hose longitudinally, while the dimensions of the tube relative to the hose are such as to prevent buckling.  The rigid tube moves perpendicularly of the length of hose, preferably about a common axis, stepwise to a series of stations.  In one station the inserted couplings are secured to the respective ends by a commercial crimper-expander.  The hose unit is then dropped or ejected to a container. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Abstract: ABSTRACT OF THE DISCLOSURE     The specification discloses a system for moving and securing an elastic sheet used in the ink duct for offset or letterpress printing machines whereby after displacement of the sheet a new unworn part of the sheet is in contact with the duct roller.  According to one embodiment of the invention a rotatable clamping spindle extends over the length of the ink duct and the spindle is provided with a longitudinal slot for attaching the sheet.  The present invention provides an ink duct in which the service life of the sheet is extended thus reducing the frequency of emptying the ink duct.  This is achieved by fastening the elastic sheet in such a way as to be tangentially displace-able with respect to the duct roller whereby after displace-ment a new unworn section is in contact with the duct roller.

Abstract: 47,735 ABSTRACT OF THE DISCLOSURE         Locking structure for maintaining a set position in assembling an annular seal ring housing to a stationary inner shroud of an annular array of vane segments of a combustion  turbine  engine.   This  permits  an adjustable assembly for obtaining concentricity between the seal and the  adjacent  rotor  structure.   Thus,  the  seal ring is mounted to the vane segments through an adjustable mount-ing arrangement  that, upon assembly of the two, permits the  seal  ring  to  be  aligned  concentrically about  the rotor.   Once  concentricity  is  obtained,  the  mounting components must be locked in such position to maintain such  concentricity.   The  present  invention  provides  a bracket attached to the adjustable mounting structure to lock it in the set position.

Abstract: IMPROVED PARTIALLY FLUID-LOCKED DRIVE TRAIN           Abstract Improved partial locking for a fluid-locked planetary gear train is provided by loosely mounting planet gears (110, 111,60,61) for movement within the chambers (100-103) which closely surround the partially locked planet gears.  The driving and reaction forces on the loosely mounted planet gears permit the planet gears to move so that their peripheral ends come into close engagement with the walls of the chambers in which the gears are mounted to further increase the fluid resistance to movement of the gears.  To obtain similar partial locking char-acteristics in either a forward or a reverse direction, the planet gear pairs and their corresponding chambers are reversed in their relative positions.

Abstract: ABSTRACT     A switched-capacitor circuit for passing an audio frequency over a predetermined range of frequencies fabricated on a monolithic semiconductor substrate is provided.  The switched-capacitor filter includes a first amplifier and a second amplifier.  A first integrator capacitor is interconnected to the first amplifier.  A second integrator capacitor is interconnected to the first amplifier.  A first input switched-capacitor is inter-connected between the first amplifier and the second amplifier, such that the first input switched-capacitor samples and holds the output of the second amplifier during a first clock phase thereby isolating the output of the second amplifier from the input of the first amplifier.          During a second clock phase the first input switched-capacitor applies the output of the second amplifier to the first integrator capacitor.  A second input switched-capacitor is provided and is interconnected between the output of the first amplifier and the input of the second amplifier, such that during the second clock phase the second input switched-capacitor applies the output of the first amplifier to the second integrator capacitor.          The switched-capacitor circuit functions such that effectively zero phase shift is introduced into the signal being processed by the switched-capacitor circuit.

Abstract: ABSTRACT      In worm fishing, the way of baiting a conventional hook permits the worm to be somehow removed rather too frequently; consequently, there is the excessive need for the re-baiting with fresh new worms. This easiness of worm removal is due to the ineffective present hook designs because worm-efficiency and natural worm-appearance are not considered.  In this invention, a portion of the shank between the eye at the free end and the barb at the other end, is bent through approximately an additional 360 degrees in any direction or profile. This results in a better baiting of the hook with the worm by making available a relatively much longer shank which would accept a much larger portion of the worm, or even the entire worm, around the hook. The overall distance between the eye and the barbed point is still maintained essentially the same for any given hook size. Hook rigidity can still be satisfactorily retained by increasing the shank cross section if necessary.

Abstract: Docket M-18 TAG ATTACHING APPARATUS Abstract of the Disclosure There is disclosed apparatus for attaching tags using fasteners of a type having a bar section and a button section joined by a filament section.  The apparatus includes a body with a pair of body sections keyed together in part by a needle having an elongated bore and a side opening.  A push rod is engageable with the bar section to push the bar section through the needle bore while its filament section extends through the slot.  Opposed operating levers are pivotally mounted on opposite side of the body.  Each lever carries a cam.  A first carrier is mounted by the body and a second carrier is mounted by the first carrier.  The push rod is connected to the second carrier.  The first carrier has a pair of carrier members and each carrier member carries a post which rotatably mounts a gear.  The carrier members are connected by a pin which rotatably mounts a pair of rollers.  Each cam cooperates with a respective roller.  A rack is secured to each body section and the second carrier has a pair of racks.  Each gear meshes with a respective body section rack and a respective second carrier rack.  A pawl is coupled to the first carrier through a lost-motion connection so that only part of the movement of the first carrier is imparted to the pawl.  Action of the operating levers causes the cams to drive the rollers to in turn drive the first carrier.  Movement of the first carrier causes the racks and gears to drive the push rod forward through a distance Docket M-318 twice as great as movement of the first carrier.  Near the end of the forward movement of the push rod, the pawl is moved to a ready position. A spring acting on the first carrier returns the carriers, the levers and the push rod to their respective initial positions and moves the pawl away from its ready position to drive a toothed wheel of a fastener advancing means to bring a bar section of the next successive fastener into alignment with the needle bore. The pawl is cooperable with a cam disposed at a preselected position so that the toothed wheel with which the pawl cooperates can be driven through a preselected angle.
