Title: An enclosed extended nip press apparatus
Inventor: FILZEN SCOTT E
IPC: D21F3/02
Filed: 1990-04-09
Abstract: An enclosed extended nip press apparatus (10) is disclosed for pressing water from a formed web (W). The apparatus (10) in-cludes a frame (12) and a back-ing roll (14) rotatably secured to the frame (12). A press member (16) cooperates with a backing roll (14) for defining therebe-tween an extended nip (N) for the passage therethrough of the formed web (W). A press blanket (18) extends in a closed loop through the nip (N), the blanket (18) having a first and a second lateral edge (20 22) and an inner and an outer surface (24, 26). A first and a second head (28, 30) are rotatably secured to the press member (16) with the first and second heads (28, 30) being disposed adjacent to and cooperating with the first and the sec-ond edges (20, 22) respectively of the blanket (18). The first and the second heads (28, 30) define first and second annular chan-nels (32, 34) respectively for the reception therein of the first and the second lateral edges (20, 22) respectively of the blanket (18). A first and a second annular seal (36, 38) are disposed within respectively the first and the second channels (32, 34) with the seals (36, 38) contacting the respective edges of the blanket (18). A first and second plurality of barbs (40, 42) extend from the first and the second channels (32, 34) respectively such that the first plurality of barbs (40) extend towards and engage the first lateral edge (20) of the blanket (18) and are disposed on the opposite surface (26) of the blanket (18) relative to the first seal (36). The second plurality of barbs (42) extend towards and engage the second lateral edge (22) of the blanket (18). The second plurality of barbs (42) are disposed on the opposite surface (26) of the blanket (18) relative to the second seal (38) so that during use of the appara-tus (10), lateral movement of the edges (20, 22) of the blanket (18) relative to the heads (28, 30) is inhibited.

Title: Dna segment encoding a gene for a receptor related to the epidermal growth factor receptor
Inventor: KRAUS MATTHIAS H
IPC: A61K47/48
Filed: 1990-11-30
Abstract: A DNA fragment distinct from the epidermal growth factor receptor (EGF-R) and erbB-2 genes was detected by reduced stringency hybridization of v-erbB to normal genomic human DNA.  Characterization of the cloned DNA fragment mapped the region of v-erbB homology to three exons with closest homology of 64 % and 67 % to a contiguous region within the tyrosine kinase domains of the EGF-R and erbB-2 proteins, respectively, cDNA cloning revealed a predicted 148 kd transmembrane polypeptide with structural features identifying it as a member of the erbB  family, prompting designation of the new gene as erbB-3. It was mapped to human chromosome 12q11-13 and was shown to be expressed as 6.2 kb transcript in a variety of normal tissues of epithelial origin. Markedly elevated erbB-3 mRNA levels were demonstrated in certain human mammary tumor cell lines. These findings indicate that increased erbB-3 expression, as in the case of EGF-R and erbB-2, plays a role in some human malignancies.

Patent CA-2077304-A1 (CA)
Inventor: STURGIS MALCOLM B
IPC: F16L37/23
Filed: 1992-09-01
Abstract: A quick-connect coupling for connecting a gas line to a gas appliance.  The coupling comprises a nipple and a socket member with a socket for  receiving the nipple.  A sleeve is slidable on the socket member from a retracted position in which the nipple may be inserted into the socket, to a locking position in which the nipple is held captive in the socket, and then back to the stated retracted position for disconnection of the nipple from the socket member.  Two valves are disposed in a flow passage in the socket member.  The first valve is biased toward a closed position and automatically opens upon insertion of the nipple into the socket.  The second valve is manually movable by means of a lever on the socket member from a fully open position for permitting maximum flow of fluid through the flow passage, through a range of movement in which  it is  only partially open to  a  fully closed position.  A detent member movable conjointly with the lever is engageable by the sleeve to prevent it from being moved to its retracted position when the second valve is fully or partially open.  The detent member is movable to a position for permitting the sleeve to be moved to its retracted position only when the second valve is in its fully closed position, thereby ensuring that flow through the second passage is completely cut off before the nipple and socket assembly can be connected or disconnected.

Title: Front jaw
Inventor: STRITZL KARL
IPC: A63C9/08
Filed: 1992-03-25
Abstract: ABSTRACT The invention relates to a front jaw (1) with a housing (2), in which is housed a release spring (40). The release spring (40) loads a pull rod (10) extending through the release spring, which pull rod acts onto the shorter lever arms (36) of two toggle levers (35) through a release plate (13), which toggle levers are pivotal about vertical axes (34) on a bearing part (20) and the longer lever arms of which toggle levers are designed as sole holders (37).  The bearing part (20) has a through opening (21) for the pull rod (10) and has at its lower end section a rearwardly directed projection (31) for abutment against the release plate (13).    The release plate (13) has according to the invention in its lower section (14) on its side facing the bearing part (20) a control surface (15) which, when viewed in a longitudinal cross section, extends upwardly and forwardly.  The rearwardly directed projection (31) on the bearing part (20) rests at least pointlike on the control surface (15) when an upwardly directed force engaging the sole holders (37) occurs.

Abstract: TITLE OF THE INVENTION:       METHOD FOR CONTROLLING RECTIFIERS          ABSTRACT OF THE DISCLOSURE:    In a method for controlling rectifiers of an inductive   element   for   reversible   energy transmission first rectifiers are connected to a primary circuit  of  the  inductive  element  and second rectifiers are connected to a secondary circuit of the inductive element.  The first and the second rectifiers are switched in a constant timing ratio.  The first rectifiers are controlled by  a  central  signal  source  with  a  constant frequency.  The second rectifiers are controlled with control signals derived from the changing potential at the inductive element.   With this method it is possible to provide a control of the rectifiers such that they are switched depending on one another without being directly connected to one another.

Title: Electrosurgical trocar assembly with bi-polar electrode
Inventor: GENTELIA JOHN S
IPC: A61B18/14
Filed: 1993-02-17
Abstract: ELECTROSURGICAL TROCAR ASSEMBLY     Abstract of the Disclosure A trocar assembly includes an elongate trocar device and a surrounding cannula.  The trocar device incorporates an electrosurgical cutting element which is used to make a guide hole for the cannula and thus enables the remainder of the trocar assembly to enlarge the puncture.  The cutting element comprises a bi-polar electrode assembly.  An electronic control circuit senses the current flow to the cutting element and, when the trocar device breaks through the wall of the body cavity being cut into, this circuit cuts off the connection to the associated electrosurgical generator.  Further control circuitry prevents a surgeon from resuming electrosurgery until a predetermined time period has elapsed.  Multiple trocars of different diameters are provided for the same assembly.
