Title: Method for transmitting a digital broadband signal in a tributary unit concatenation via a network of a synchronous digital multiplex hierarchy
Inventor: MUELLER HORST
IPC: H04J3/06
Filed: 1990-11-27
Abstract: A pointer is allocated to the first tributary unit in a tributary group system for determining its position in the frame; the other tributary units receive a system indicator instead of a pointer. Each network node facility along a transmission link must recognise the tributary group system and forward its tributary units in the correct order. If a clock adaptation is required in the first tributary unit, a phase shift must also be initiated in all others. This requires hardware and software. This can be omitted if a pointer (PTR1 to PTR5) with the value of the positioning determination of the first tributary unit (TU-121) is allocated to all tributary units (TU-121 to TU-125) containing the broadband signal (DSa). The individual tributary units (TU-121 to TU-125) can then pass through the network node facilities independently of one another - if necessary with an individual phase shift (PS). At the receiving end, the tributary group system is restored after recognition of the pointers (PTR1 to PTR5) in that leading tributary units (TU-122, TU-125) are delayed by delay sections (L2, L5). <IMAGE>

Title: Surgical cutting instrument
Inventor: PINGLETON EDWARD D
IPC: A61B17/32
Filed: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE A  surgical  cutting  instrument  is  disclosed  for percutaneously debulking tissue through an access sheath commonly  used  in  minimally  invasive  laparoscopic  or endoscopic surgical  procedures.   The cutting instrument includes a inner rotary member tube having a cutting edge at the distal end thereof for cutting and slicing tissue.  The distal end of the cutting member tube extends from the distal end of a stationary sheath which prevents tissue from wrapping around the inner cutting member tube.  The inner cutting  member  tube  includes  a  hollow  passageway  for suctioning and aspirating tissue and fluid through the tube and into a collection chamber or out through a vacuum or suction  line  attached thereto.   The  instrument further includes an outer safety shield having a rounded distal end for preventing the puncture of a surgical tissue bay or from unintentionally cutting tissue by the attending physician. The outer shield has a channel across the distal end through the hollow passageway therein for feeding tissue into the cutting edge and controlling the vacuum applied to the tissue.  Vacuum or suction control ports are included at the proximal end of the inner cutting member tube and stationary sheath for also controlling the amount of vacuum or suction applied to the tissue.   The surgical cutting instrument includes a control handle for grasping by the physician.  A removable collection  chamber  is  connected  to a  coupler connected to the stationary sheath for collecting tissue therein.  The inner cutting member tube extends through the collection  chamber  to  a  drive motor  or  to  a  remotely positioned  rotary  drive  mechanism.    A  vacuum  line  is attached to the collection chamber for drawing tissue and fluid through the inner cutting member tube and into the collection chamber.

Abstract: A captive ball and socket joint where the socket is made from bearing material which is encased in a metal shell, thereby forming a socket around the ball head an t;he end of a ball stud. The metal shell is cup-shaped and lass its base wall apertured so that the ball formed with internal wrenching socket is accessible through the aperture when the ball and the bearing socket are placed into the cup-shaped shell. A flat steel connector lug is pierced with an opening and the wall of the metal cup-shaped shell is secured within the opening by welding. The edge portion of the shell is deformed to render the ball and socket captive in assembly with the lug. The hole in the base wall of the shell permits access for insertion of a rotary drive tool to engage a formation in the ball component to rotate the ball component and secure it to a machine element such as a brace or bracket. The bearing socket can be one or two pieces and can be made from metal bearing material or a plastic bearing material. The method of assembling the joint envisages use of techniques to avoid destruction of the characteristics of the bearing material.

Abstract: PINCH RESISTANT CHILD'S TOILET SEAT INSERT                   ABSTRACT OF THE DISCLOSURE           A pinch resistant toilet seat insert is provided for use in combination with conventional toilet seats to restrict the dimension of the opening thereof to facilitate safe and effective use by children.   A seat insert body forms an outer peripheral recess at the sides thereof or at the sides and rear portions thereof for supported and positioned engagement with the inner peripheral portion of a conventional toilet seat.   The forward side edge portions of the seat insert body are recessed so as to locate  the  frontal  contact points of  the  insert  and  the conventional toilet seat so as to be inaccessible and to thus minimize the possibility of pinching during use.  The seat insert body forms outer peripheral channels to conduct accidentally spilled liquid between the seat insert body and the conventional toilet seat so that it will drain into the toilet.  The seat insert is of rigid uni-body design and is provided with a rearwardly extending angulated tailpiece having pivots that establish  pivotal  connection  with  the  seat  pivot  of  a conventional toilet seat or with other structure.  The tailpiece includes a downturned extremity which locates the pivot axis so that in the upstanding position the center of gravity of the seat insert will be located over-center with respect to the pivot axis.  the tailpiece also achieves positioning of the insert relative to the seat opening in the lowered position and positions the seat insert in a spaced non-contaminating position wit the toilet seat or flush valve when upstanding at its raised position.
