Title: Device for transmitting signals between two terminals
Inventor: WOLF KLAUS-UWE
IPC: H01R35/02
Filed: 1996-03-28
Abstract: A device for transmitting signals between two terminals is indicated, where at least one of them is moveable with respect to the other.  The terminals are connected by at least one line wound in turns, which is stored in an essentially circular cassette.  The turns of the line are divided into an inner winding area and an outer winding area running in different directions, between which an approximately U-shaped reversing area is located.  A one-piece ring-shaped guide (14) is located between the two winding areas and surrounds the reversing area of the turns. At least on the inside facing the inner winding area, the guide (14) has protrusions (15) that are distributed around the entire periphery and face radially out toward the center point (M), and which are offset with respect to each other in the peripheral direction.  On the inside that faces the winding area, it has convex curved walls (16) between each two protrusions (15), where their minimum distance from the center point (M) of the guide (14) is larger than the minimum distance of the protrusions (15) from the same point.  In the transition areas between the walls (16) and the protrusions (15), at least on the side that faces away from the direction of rotation of the guide (14) when the internal winding area increases, at least one nub (17) is located, which has a smaller minimum distance than the pertinent wall (16), but a larger minimum distance than the pertinent protrusion (15), from the center point (M) of the guide (14).

Title: Umbilical cord clamp applicator and transector
Inventor: SEETHRAM KENNETH
IPC: A61B17/12
Filed: 1993-04-29
Abstract: A device used at time of childbirth, for fastening a plastic umbilical cord clamp to an umbilical cord, securing the proximal end of the cord, and accomplishing cord transection comprises a rigid frame, an articulating clamp, a clamp applicator, a trigger, a cutting apparatus and a platform.  The articulating clamp and clamp applicator run parallel to, and on opposite sides of the platform.  The articulating clamp and clamp applicator are linked mechanically and operate in conjunction.  The trigger and cutting apparatus are linked to each other, are integral with, and connected to the frame by means of horizontal and oblique grooves.  The umbilical cord is placed within the platform, and as the handles of the articulating clamp and the clamp applicator are depressed, the umbilical cord clamp becomes fastened to the cord, while the proximal end of the cord becomes secured. Trigger depression results in the cutting apparatus blade to pass perpendicularly across the umbilical cord, transecting it. Upon release of the clamp, the biased clamp applicator handle opens, releasing the distally clamped cord, while the articulating clamp remains closed, securing the proximal cord end. The newborn is safely and rapidly separated from the mother by use of this device, in a simple two-step maneuver.

Inventor: STEIGER ROLAND
IPC: C08C2/00
Filed: 1996-12-31
Abstract: A process for the recovery of an initially living polymer from a cementproduced in a polymerisation process. The living polymer cement is shortstopped, washed, stabilised, coagulated and dried. The recovery process comprises adding a short stop to the polymer in the cement, washing catalyst residue from the polymer with water, adding an antioxidant Irganox 1520 to the cement to stabilise the polymer, adding epoxidised soya bean oil to the polymer to stabilise the polymer against colour degradation, and coagulating and drying the polymer. The pH of the cement is regulated in the range of from about 6 to about 7 during the catalyst wash and the coagulation steps of the recovery process. A product of the process is also described. The product and process provide for use of a preferred anti-oxidant system, which overcomes health concerns associated with existing anti-oxidant systems used in anionic polymerisation processes, while providing a polymer product that has excellent colour and stability characteristics suitable for use in high impact polystyrene applications.
