Title: Forming a fiber web using a widened jet of suspension
Inventor: MEINECKE ALBRECHT
IPC: D21F9/00
Filed: 1991-02-15
Abstract: FORMING A FIBER WEB USING A WIDENED JET OF SUSPENSION        ABSTRACT OF THE DI DISCLOSURE          A method and apparatus for minimizing damage from impingement of a jet of fiber suspension on a wire, roller surface or the like defining an inlet slot to a forming section which is opposite the headbox outlet nozzle by increasing the angle of spread and therefore the height of the jet where it impinges upon the surfaces.  The opening angle of the jet is at least 3°, preferably between 15° and 60°.  The jet widens, that is becomes taller, upon leaving the outlet nozzle from the headbox so as to impinge upon one or both of the moving surfaces defining the inlet slot, which surfaces may be defined by one wire or two wires or a wire and a roll.  The outlet nozzle from the headbox may have a flow body in it which divides the flow before its exit from the outlet nozzle.  A flow constriction at the outlet region of the nozzle, past the flow body if present, widens the jet as it leaves the nozzle.  There may be inwardly directed ledges on the lips defining the nozzle near the nozzle outlet. There may be air inlets in one lip and a hump inside the nozzle on the other lip opposite the air inlets.

Title: Hinged mold block conveyors in tube making apparatus
Inventor: LUPKE MANFRED A A
IPC: B29C49/00
Filed: 1991-04-15
Abstract: ABSTRACT     The invention concerns apparatus for molding tube utilizing a travelling mold tunnel.  The tunnel is made up of mold blocks each comprising parts which are hinged together to be closeable to form the tunnel and openable to release tube from the tunnel.  The opened mold blocks from the downstream end of the tunnel are returned to the upstream end to reform the tunnel about an extrusion nozzle for thermoplastic extrudate without changing the orientation of the axes of their bores so that said axes always remain generally parallel with the axis of the mold tunnel.  Mold blocks removed from a downstream end of the mold tunnel are returned to the-upstream end at a speed greater than the travelling speed of the mold tunnel.

Inventor: SCHANEN PAUL C
IPC: A61B6/03
Filed: 1991-05-09
Abstract: A data acquisition filter for a dual beam CT machine uses two spectral filters for alternately receiving the signal from each detector depending on the state of the xray beam. When one filter is filtering the detector signal, the other filter is in a "hold" state where its output and internal values are frozen. Each filter effectively filters only the signal occurring during one beam state without being effected by the signal occurring during the other beam state or by the passage of time during the other beam state The output of the filter in the holding state is constant and may be sampled at any time during this period.

Title: Code acquisition method and circuit for a spread spectrum signal receiver
Inventor: ZAREMBOWITCH ALAIN
IPC: H04B1/707
Filed: 1990-10-02
Abstract: The spread spectrum signal (S1) is converted into a digital binary signal (S2) having one binary character, and this binary signal is applied to several parallel detector circuits (10) each of which detects a distinct code position. Each detector circuit (10) simultaneously receives a phase-shifted version of a binary reference code (CR) and produces a signal (B3) which has a first binary state when the received signal corresponds to the code position of the detector circuit, and has a second binary state when this is not the case. The output signals (B3) are combined and/or coded in order to identify the correct code position for demodulating the received signal. The invention is used in communication systems receivers.

Title: Device for singularizing drop wires in warp-thread drawing-in machines
Inventor: WILHELM HANS
IPC: D03J1/14
Filed: 1991-07-04
Abstract: Abstract The device contains a selecting member (31) for the  drop wires  fed  in  the  form  of  a  stack,  which selecting member (31) separates the drop wires from the stack and prepares them for the drawing-in of the warp threads.  The selecting member is  formed by a means, preferably a friction wheel (31), acting on the front end of the drop-wire stack and frictionally transporting the actual frontmost drop-wire      from the drop-wire stack into an intermediate position.        Consequently, the drop wires do not need to have any specific configuration at the point of application of the selecting member and they also do not need to be lined up or arranged in a specific manner. The friction wheel contacting the drop wires at their front end is able to singularize all types of drop wire.                                                (Fig. 2)

Filed: 1991-12-04
Abstract: ABSTRACT OF THE DISCLOSURE            A method for improving the seismic resolution of geologic structures is disclosed.  Refracted wave arrivals are gathered into common midpoint trace gathers.  Data representations originating inside a critical offset distance are muted, and the remaining data is tau-P summed and projected into zero source-to-receiver offset.  Constant velocity stacks can then be displayed.  A plurality of common midpoint trace gathers can be used to generate multiple panels of tau-P sums.  Portions of several of these panels can be combined to provide a complete image of the subsurface reactors.  A near-surface velocity model can then be designed, to provide a solution to near-surface statics in seismic traces.
