Granted: 1997-04-22
Abstract: Process in manufacturing paper wherein stock is prepared using cellulose fiber material which contains calcium sulfate (gypsum), said material being disintegrated in an aqueous medium in order to form part of the stock for the paper to be pro-duced. The characterizing feature of the process is that (a) carbonate ions and/or hydrogen carbonate ions (CO32- or resp. HCO3-) are supplied to the aqueous medium, and (b) the pH in the aqueous medium is adjusted to an alkaline value so that calcium carbonate precipitates and forms part of the suspension. There are overall major advantages provided by the pro-cess in the context of applying gypsum coatings on paper, inasmuch as broke can be reused in the process without any trou-blesome gypsum precipitation. Moreover a new grade of coated paper is described, the characterizing feature of this paper being that the filler of the base paper consists entirely or partly of precipitated calcium carbonate (PCC) and that the pig-ment of the coating layer consists entirely or partly of calcium sulfate.

Title: Coinjection molding apparatus having rotary axial actuating mechanism
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/16
Filed: 1992-05-11
Granted: 1999-11-09
Abstract: Valve gated injection molding apparatus for coinjecting and/or sequentially injecting two different fluids through a gate into a cavity. An elongated valve pin member is received in an elongated valve sleeve member in alignment with the gate and both are reciprocated rotatably as well as axially by separate actuating mechanisms to control the flow of the fluids through the gate. Each actuating mechanism has a piston driven rack member to provide rotary motion which is then converted to axial movement of the corresponding valve member between the retracted open and forward closed positions. In one embodiment, helical threads on the valve members engage fixed teeth extending inwardly from the surrounding nozzle to convert the rotary motion of each valve member to corresponding axial movement. Linear position transducers on the rack members provide for accurate control of the valve members. This accurate control and the reduction in force required by these rotary axial actuating mechanisms minimizes wear resulting from repeated seating of the valve members.

Title: Transition joint for oil-filled cables
Inventor: WENTZEL CARL J
IPC: H02G15/08
Filed: 1991-09-13
Granted: 2002-11-12
Abstract: A transition joint for sealing an electrical coaxial cable (10) having an oil-impregnated or fluid filled layer (1t7. The trans-ition joint has two primary elements, an electrically insulative elastomeric tube (26) and a heat recoverable sleeve (32). In connect-ing a paper-insulated lead jacketed cable (10) to an extruded dielectric cable (40), the elastomeric tube (26) is placed in tight con-formity around the paper layer (16), slightly overlapping the lead jacket (12) and the central conductor (18), and further partially overlapping a connector (44) joining the conductors of the cables. The heat recoverable sleeve (32) is then contracted over the elastomeric tube (26), overlapping the lead jacket (12) and the central conductor (18), and partially overlapping the connector (44). The heat recoverable sleeve (32) mechanically restricts the elastomeric tube (26), preventing the elastomeric tube (26) from swelling which, in turn, precludes absorption of the oil, which would otherwise cause the elastomer to degrade. If the cable has an additional semiconducting layer, a high-dielectric tape may be used for dielectric stress control.
