Abstract: ABSTRACT      The invention is concerned with a continuously variable transmission  mechanism  which   incorporates  a   variator and an epicyclic gearset.   Several brakes and/or clutches are arranged for selectively coupling together or holding stationary  various  parts  of  the  mechanism  to  provide forward  and  reverse  transmission  ranges  within  which the overall transmission ratio can be varied by the variator. In  a  first mode  of  operation  the  drive  is  through  the variator,  the  epicyclic  gearset  acting  as  a  reduction gearing  and  a  further  reduction  gearing  to  an  output co-axial with the  input.   In a second mode,  the gearset is  locked  up  to  provide direct  drive  from  the  variator output to the reduction drive.  The ratio of the reduction drive  corresponds  to  the  maximum  step-up  ratio  of  the variator so that in the second mode, with maximum variator step  up  ratio  the  overall  transmission  ratio  is  1:1  in a third mode the input is coupled directly to the output to  bypass  the  variator  and  provide  direct  drive.    The epicyclic gearset can be used in a reverse mode to provide a reverse gear.

Abstract: Abstract of the Disclosure Method and apparatus for enabling measurement of corona drum current in an electrostatic copier as a maintenance aid. A rotatable drum supports a photoconductor with a conductive backing connected to a ground current return path including a slip ring.  In the maintenance mode, the ground path is opened allowing drum current to flow through a current measuring cir-cult including a pair of jacks to which a measurement device may be connected.  The current measuring circuit also develops a potential which is representative of whether or not the current return path is grounded.  This potential is coupled to a moni-toring device where it may be used to drive a display.  A method of  aligning a corona generator employing the corona current  measuring apparatus of the invention is applicable for aligning corona generators in situ in an electrostatic copier. The alignment method includes steps of energizing a selected corona generator, interrupting the normal ground return path, providing a current path from the photoconductor and coupling the current path to a measurement device.  For alignment purposes at least two measurements are made, each measurement is made while different portions of the corona generator are masked. The measurements provide a measure of the corona current gen-erated by two different portions of the generator which is useful in aligning the generator.

Abstract: ABSTRACT           A sealing device for sealing between a screw and a nut threaded thereon.  The device is particularly suitable for sealing a ball type screw wherein the thread on the screw includes a helical rounded groove and wherein the thread crest is a cylindrical surface.  The device is mounted in a recess of the nut and includes and annular elastomeric member having on its inside surface ribs to seal against the screw thread crests and a projection to seal the groove.  The radially outer portion of the elastomeric member is generally U shaped with radially extending ribs axially spaced to provide a recess there-between.  The outer tips of the ribs seal against a cylindrical wall of the nut recess but each tip is deflectable out contact with much wall when the fluid pressure is high on the axially outer surface of that tip to permit the high pressure fluid to enter the recess between the lips to press the outer tip into tighter sealing engagement with the nut wall and to press the projection and ribs into tighter sealing engagement with the screw.  The lips are backed by rigid washers to permit the deflection and tighter sealing of the lip tip and thus the device is suitable or high pressure.

Abstract: COMPRESSIBLE ELECTRICAL CONNECTOR    WITH POSITIVE MECHANICAL LOCK    ABSTRACT OF THE DISCLOSURE     This disclosure depicts a ductile metallic electrical and mechanical connector for attachment to one or more electrical cables and formable by a compressible process.  The connector comprises at least one bifurcated body member having first and second leg portions initially connected by a reduced cross-sectional thickness portion of the body member to provide a plastically flowable hinge connection.  The first and second leg portions define an initial predetermined angle such that the body member can laterally engage an uninsulated section of an electrical cable.  The first leg has on the end opposite the reduced thickness portion an axially extending rib member and axially extending inner and outer ridges disposed on either side of the rib member.  The second leg has on the end opposite the reduced thickness portion axially extending inner and outer fingers.  The rib member, the inner and outer ridges and the inner and outer fingers are oriented such that the outer finger lies between the outer ridge and the rib member and the inner finger lies between the inner ridge and the rib member, when the body member is closed about an uninsulated section of an electrical cable.  The enclosure occurs by pivoting of the leg members about the reduced thickness portion in response to hand applied external pressure.  The inner and outer fingers and the rib member are deformed to form a positive mechanical lock when an external crimping force is applied radially to the body member.

Granted: 1981-09-15
Abstract: H-SECTION CARTON FORMING MACHINE A machine for forming an H-section carton (19) from three corrugated blanks -- two section blanks (21a and 21b) and a main body blank(23)--is disclosed. The machine has a generally L-shaped silhouette, with one leg of the L shape generally defining the path of travel of the section blanks and the other leg defining the path of travel of the main body blank. A supply of vertically oriented section blanks are located on opposing sides of the section blank leg. The two section blanks facing one another are simultaneously moved toward the main body blank leg, along parallel paths. The section blanks are first moved past glue heads (61a and 61b), which apply glue to the center region (22a and 22b) of the facing surfaces of the section blanks. Then, section forming mandrels (85) ram the section blanks toward one another into a U and H-section forming die (87). More specifically, the section modules first deform the section blanks into a U-shape. Then, the cross-members of the U-shaped sections are pressed together, whereby an H-shaped section is formed. While the H-section is being formed, a main body blank is removed from a supply of vertically oriented main body blanks and moved past glue heads (63a), which apply glue to edge tabs(49, 51, 53, 55, 57 and 59). Main body blank movement stops when the main body blank lies in front of a final forming die (94), which die is aligned with the H-section. When H-section formation is completed, an expandable mandrel (91) having a vertical slit picks up the H-section and rams it into the main body blank. Continued movement of the expandable mandrel rams the H-section and the main body blank into the final forming die, causing the edge tabs of the main body blank to be bent around the outer surface of the legs of the H-section. Thereafter, the expandable mandrel expands so as to press the legs of the Hsection against the edge tabs.
