Abstract: ABSTRACT         A linear motor comprised of a plurality of primary coils arranged and spaced sequentially. A fluid intake manifold and a fluid exhaust manifold with at least one conduit in fluid communication between the intake and exhaust manifolds, such that the fluid intake manifold, fluid exhaust manifold and conduit are associated with the primary coils to control the temperature of the motor.          A robotically controlled linear motor apparatus for manipulating physical arms in one or more dimensions, with at least one linear motor comprised of primary coils sequentially and spacially arranged and a secondary coil positioned magnetically adjacent to the primary coils. A fluid circulating manifold as described above.  A commutator for selectively energizing the primary and secondary coils to create a magnetic imbalance therebetween so that the secondary coil is urged in a direction opposite to that of the flux imbalance.  A first arm is fixed to one the secondary coils and a second arm is fixed to the primary coils so that when a secondary coil moves, the first arm moves in reference to the second physical arm.  A control for manipulating the first physical arm in one or more dimensions by selectively energizing the commutator to energize the linear motor causing the secondary coil and attached physical arm to move in relation thereto.

Title: Sterilized, unitary container and fluid transfer set
Inventor: HARVEY ROGER W
IPC: A61L17/00
Filed: 1987-12-04
Granted: 1992-04-28
Abstract: Abstract of the Disclosure A method of forming a unitary, sterile fluid dispensing assembly (10) includes forming a fluid-filled container (12) with a vinyl dispensing port (14) and forming a fluid transfer set (17) with a vinyl spike connector (40).  The spike connector (40) is inserted into the vinyl dispensing port (14) thereby placing the set in fluid flow communication with the fluid (F) in the container (12).  The assembly (10) is sterilized in an autoclave (A). The heat of sterilization melds at least a surface portion (46) of the vinyl spike connector (40) and softens an interior adjacent surface portion (18) of the port (14) on the container (12).  After sterilization, the transfer set (17) is permanently bonded to the container (12).          The presence of the fluid (F) in the transfer set during sterilization prevents fusing and closing of the lumens of the set due to the heat of sterilization.

Inventor: MINAMI HIROO
IPC: B29C45/00
Filed: 1988-03-16
Granted: 1991-04-23
Abstract: ABSTRACT OF THE DISCLOSURE     A method of making an injection-molded slide fastener slider includes a first injection-molding step for forming a slider body having an integral arch-shaped support lug and a second injection-molding step for forming a pull tab threaded through a transverse hole in the support lug.  For pivotal connection of the pull tab with the support lug, a mold used for achieving the method includes a combination of a main slide core and an auxiliary slide core slidably associated therewith.  In the first injection-molding step, the auxiliary slide core is held in a first position in which the two slide cores jointly have a shape corresponding to the shape of the transverse hole while blocking fluid communication between first and second mold cavities in which the slider body and a body of the pull tab are formed respectively.  Then the auxiliary slide core is moved to a second position in which a third mold cavity corresponding in shape to a pintle of the pull tab and communicating with the second mold cavity is defined between the slide cores and the underside of the already molded lug.  Thereafter, the second injection-molding step is carried out.
