Abstract: This method is practiced by first providing a plurality of spools of amorphous steel strip in each of which the strip is wound in single-layer thickness. Then, in a pre-spooling machine, the single-layer thickness strips are unwound from said plurality of spools and combined to form strip of multiple-layer thickness which is wound onto a plurality of master reels, on each of which the strip is wound in multiple-layer thickness. These master reels are then placed on a plurality of payoffs, and the multiple-layer thickness strip is unwound from these payoffs and combined into a composite strip that has a thickness in strip layers equal to the sum of the strip layers in the combined multiple-layer thickness strips. Then the composite strip is cut into a plurality of sections, or lengths, of composite strip, and with these sections a hollow core form is constructed, which form has a window about which the sections are wrapped.

Patent CA-2039546-A1 (CA)
Title: Robotic articulation
Inventor: CULP GORDON W
IPC: B25J17/02
Filed: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE Actuators of rigid electrically actuatable material provide articulation for robotic limbs. Piezoelectric actuators, for example, may be used in various embodiments of robotic joints to rotate a cylindrical or spherical connection or to translate a rod. Opposing pairs of actuators engage in smooth walking motion and maintain a vise-like grip on the robot limb at all times. The traction surfaces of the actuators contact the robot limb with zero clearance. Unlike the use of conventional bearings, zero clearance and full area contact provide relatively large mechanical stiffness that allows very precise positioning of robot limbs without mechanical oscillations of the extremities. With adequate limb rigidity, slop is essentially eliminated from the joints. The smooth walking motion of the actuators achieves high mechanical efficiency by eliminating sliding friction. The joints operate in air or space vacuum without lubrication and with negligible heating. Relatively large forces and torques are developed at relatively slow speeds. Size of the robotic joints can range from relatively large to microscopic.

Abstract: MODULAR LINK CONVEYOR SYSTEM                            ABSTRACT    A conveyor system (10) utilizing substantially V-shaped modular links (14) is disclosed.  A plurality of transversely mounted cross rods (20) retain the links (14) together, thereby forming the conveyor belt (12).  The apex (16) of each link (14) includes an elongated slot (22) to allow longitudinal freedom of movement to the conveyor belt (12).  Special side lines (26) are adapted to engage conveyor guide rails (42, 44) integral with a support frame (40).  Each side link (26) is formed by including a depending arm (27) having a transversely extending tab (28) on a modular link (26).  A locking tab (30) is placed within a corresponding slot (32) in each side link (26) to retain the cross rod (20).  The combination of the shape of the links (14, 26) and the longitudinal freedom of movement of the conveyor (12) allows substantially unrestricted motion through curves and bends.  In an alternative embodiment, upstanding fins (78) can be provided on one or each leg (18) of a link (14).  The angle of the fins (78) to the forward travel gives better lateral support to the product on the conveyor (10).  Fins (78) of an increased height can be provided on one or more rows to form a pusher to positively feed the product when necessary such as going up an incline.  Trays can be formed by combining rows and columns of links (14) having the fins (78).

Inventor: AMIT NETA J
IPC: G06F9/46
Filed: 1992-02-12
Abstract: A   multi-processor   computer   system   executes   a single-thread  program  having  a  plurality  of  callable procedures in program modules. The local memory of each processor contains a program stack, the object code of each module that executes on that processor, and an agent object and  data  structures  containing  linkage  information.   In addition, the local memory contains a c-stub module for each procedure executable on a different processor, and a s-stub module for each procedure in local memory that can be called by  a procedure  executing  on  another processor.   When  a procedure P1  executing on processor A wishes to  call  a procedure P2 which executes in processor B,  it issues a local call to P2's c-stub in processor A's local memory. The P2 c-stub then invokes the agent process in processor A, which communicates with a corresponding agent process in processor B.  The agent process in processor B causes a P2's s-stub in processor B to issue a local call to procedure P2. The  return  from  a  procedure  follows  the  same  path  in reverse.   Each processor  independently maintains  its own version of the program stack, with stack entries referencing the locally executable procedures,  local  stubs,  or local agents.  With each local call or return, the program stack for that processor is updated appropriately.  Because each processor  independently  maintains  its  own  stack,  remote procedure calls are not constrained by the past calling history of a process.  A procedure P1 in processor A may call a procedure P2 in processor B, which may in turn call another  procedure  P3  in  processor  A.   It  is  therefore possible  for  a  conventional  single-thread program to be converted to operation on a multi-processor system without any significant modification to the source code.
