Title: Cassette for a typing ribbon for typewriters
Inventor: GILLIO CLAUDIO
IPC: B41J35/23
Filed: 1990-11-16
Abstract: ABSTRACT OF THE DISCLOSURE         A unitary cassette for a typewriter comprises a container and two arms.  The container comprises two support elements and which project from the bottom and which are capable of rotatably supporting a supply spool and a take=up spool for a correction ribbon.  Two guide elements projecting from the ends of the arms guide a portion of the ribbon below the typing ribbon, and a tensioning device holds the ribbon taut.  The cassette can be mounted on a carriage of the machine by means of two projections projecting from the underneath of the bottom and which are capable of being pivotally mounted in two respective grooves and moving against two co-operating surfaces for oscillating movement about an axis parallel to the roller.  A pin on one side of the container can be removably engaged into a seat of a connecting lever of the machine, which is connected to a displacement means.

Title: Drum type agitating and mixing machine
Inventor: HENDREN CHARLES W
IPC: B01F33/40
Filed: 1990-12-17
Abstract: ABSTRACT OF THE DISCLOSURE     A drum type agitating and mixing machine for treating garments or fabric in liquid such as in washing or dyeing wherein a rotatable drum partially submerged in liquid along one side includes inwardly projecting hollow ribs arranged to contain air when the rib is outside the liquid in the machine.  Each rib defines a pumping chamber having an inlet opening arrangement for liquid and an outlet arrangement for air trapped within the rib and the liquid that fills the rib so that liquid enters each rib from at one area of the rib and pumps air trapped within the rib out through an outlet arrangement which is axially spaced from the inlet.   Flow of air out the outlet openings is slower than inflow of liquid into the chamber.   Liquid contained within the  rib drains therefrom through the outlet openings as each rib moves over the surface of liquid in the drum and is inverted.  A one-way valve admits liquid into the rib chamber but does not let it flow in the reverse direction to ensure that liquid will drain from the outlet openings only.  Pumping of air while the ribs are immersed causes air bubbles to be generated beneath the surface of the liquid in which the drum is rotated to promote intimate mixing of the liquid.  The axial spacing of inlet and outlet transfers liquid axially within the drum.     (WWB0013-HENDREN.APP)

Title: Collapsing mandrel apparatus for manufacturing plastic couplings
Inventor: MORAN THOMAS F JR
IPC: B29C57/00
Filed: 1991-02-14
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus and method for the manufacture of plastic couplings for joining together two lengths of plastic pipe is provided.  The couplings are manufactured from blanks of plastic material, such as polyvinyl chloride, which are heated to the thermoplastic state.  The blanks are expanded between two mandrels which come together inside the ends of the blank.  The mandrels have an outer member with a thin walled section and a nosepiece inside of that section which collapses at the end of the inward stroke of the mandrels so that the center shoulder of the coupling is not as wide as that of the prior art coupling.  This results in a coupling which is shorter and lighter than the prior art coupling and yet is the full equivalent of the prior art coupling.

A bias spring acts, between a second similar cam surface on the opposite side of the stem and the disk holder, to maintain the first cam surface in contact with the disk holder. The orifice tube has a removable boost end cap for providing a boost action to the diaphragm. One type of boost end cap is snapped in position over the end of the orifice tube and has a plurality of fingers with latch portions that engage an annular groove on the orifice tube. One of the fingers has a hook end that forms a guide for the rear of the cam stem in a sliding contact. A hole in the end cap reduces the boost effect. Another type of boost end cap has a pair of arrow-shaped fingers that engage a pair of retention slots in the end of the orifice tube and a guide finger that engages a guide slot on the tube. The end of the guide finger engages the rear of the cam stem.
