Title: Process for cold pressing a conical external thread
Inventor: KELLNER URS
IPC: B21K1/56
Filed: 1989-01-20
Granted: 1993-06-15
Abstract: ABSTRACT OF THE DISCLOSURE The process is carried out using a press tool which has a plurality of dies which are arranged around a longitudinal axis and are radially displaceable with respect to this axis.   The radially inner surfaces of the dies correspond to segments of the conical thread to be pressed.         During  pressing  of  a  conical  thread  in  a cylindrical workpiece, the dies are first drawn apart in  the  radial  direction  and  the  workpiece  is  then pushed  between  the  dies,  along  a  length  which corresponds to only a few thread turns.  The dies are then pressed toward one another in order to press into the workpiece a short conical thread in which only the first thread turn may be formed to its  full depth. After the dies have been drawn apart, the workpiece is displaced between the dies through a further length which  once  again  corresponds  to  only  a  few  thread turns.   When the dies are pressed toward one another again, the previously pressed thread turns are pressed deeper into the workpiece and additional thread turns are formed.   This process is repeated several times until  the  conical  thread  has  been  pressed  to  the predetermined total length.         Each  time  the dies  are  drawn  apart, the workpiece is rotated through an angle which corresponds to part of the circular sector of a die, in order to avoid throwing up a burr between the dies which have been pushed together.         An  apparatus  suitable  for  carrying  out  the process has an electronically controlled hydraulic unit which draws apart and presses together the dies and feeds and rotates the workpiece as a function of the diameter of the workpiece.

Abstract: ABSTRACT        A method for joining together two or several overlaying sheet formed members(10,11), metal or non-metal, at which a coaxial arrangement of a punch(12) ,a die(9) and an anvil(Y) are caused to cooperate by means of their relative movements.  The punch(12) (or die 9) is caused by means of applied forces to carry out a first movement in a first direction coaxially towards said die(9) (or punch 12) to a first predetermined relative position between punch and die which is independent of the thickness of or number of the sheet-formed members(10,11). Thereafter the anvil(y) is caused by means of applied fomces to move in the opposite direction coaxially towards a second relative postion between the anvil(Y) and the die(9) (or punch 12) which position is also independent of the thickness of or the number of the sheet-formed members(10,11). The anvil(Y) is  axially blocked in said second relative positon and said punch(12) (or die 9) is caused by means of applied forces to carry out a second movement in said first direction coaxially towards said anvil(Y) to a third relative position between the anvil(Y) and the punch(12) (or die 9) which is dependent on the applied forces, the thickness, the number  and the material of the sheet-formed members(10,11).

Abstract: Abstract of the Disclosure A balance system for an internal combustion engine or the like includes a counterbalance weight pivotally mounted to the crankcase and driven in a reciprocating manner by a link assembly connecting the weight to an eccentric on the crankshaft.  The pivoting weight not only counterbalances the piston acceleration and deceleration forces but also cancels the torsional forces created by the weight as it pivotally moves through an arc in response to piston movement.  This is accomplished by locating the center of gravity of the balance weight between the piston bore centerline and the stationary pivot of the balance weight itself. This location for the center of gravity causes a torque to be generated by a force couple created by the piston inertial force vector, the balance weight interial force vector, and the distance between them.  This torque counteracts the torque generated by angular acceleration of the balance weight itself, to thereby substantially eliminate all torsional vibrations.

Granted: 1993-07-20
Abstract: ABSTRACT       An apparatus for implementing, in hardware, clipping and inter-coordinate comparison logic in a graphic display subsystem. Clipping is necessary when an object to be displayed is defined as being only partially contained within a pre-determined window on a video display. For example, if a rectangular window is defined in the upper left hand corner of a video display, and a line has been defined which extends from the upper left-hand corner to the lower right-hand corner of the display, the portion of the line which is outside the defined window is not displayed, i.e., it is clipped. Additionally, if a line of text is wider than the window, the portion of the line of text which is outside the window must also be clipped. Calculations in the nature of comparisons are performed in hardware for use by a graphical subsystem for clipping images to be displayed on a video display in hardware whenever possible, leaving for software only those images, or portions of images which cannot be reliably clipped using the hardware of the graphical subsystem.

Abstract: MULTIDIRECTIONAL REINFORCEMENT TEXTURES MADE OF  CERAMIC FIBERS HAVING A SILICON COMPOUND BASE     ABSTRACT OF THE DISCLOSURE           In order to obtain a reinforcement texture made essentially of silicon compound based ceramic fibers in the production of a composite material, the fibers are spun from a ceramic precursor in the molten state, after which they are submitted to a partial cross-linking in view of making the fibers infusible.   The cross-linking of the fibers in the precursor in the infusible state is continued and, while they are maintained in the organic state, the cross-linked  fibers  are  submitted  to  one  or  several textile-forming  operations,  such  as weaving,  layering, needling...  in order to arrive at the multidirectional texture.    Then,  the  texture  is  submitted  to  a  heat treatment by pyrolysis to induce the ceramic state of the fibers  and  so  obtain  the  required  texture,  which  is essentially  made  of  ceramic  fibers  having  a  silicon compound base, in particular silicon carbide.
