Title: Process and apparatus for forming a composite product
Inventor: OATLEY JOHN A
IPC: D04H13/00
Filed: 1991-09-11
Abstract: Composite products, comprising a wad of fibrous material sandwiched between a non-woven fabric carrier and a liquid-impervious backing are formed by forming the wad on the carrier, moulding the wad and carrier to have a desired configuration, stabilizing the wad and bonding it to the carrier, applying the backing and cutting the wad with a border of carrier and backing from the rest of the carrier and the backing. The carrier is sheet-like and a number of the wads are formed thereon in a continuous manner. The wads are stabilized by means of a foamed acrylic binder that is sprayed onto the wads and sucked through the wads and onto the carrier by a suction applied to the underneath of the carrier. The wads and carrier are then heated to cure the binder. Instead, the wad can include thermoplastic particles so that the wad is stabilized and bonded by being heated.

IPC: H04Q11/04
Filed: 1992-03-13
Abstract: In known repeaters complying with CCITT Recommendation G.958, repeater sections are monitored by monitoring the transmission error probability of SDH signals (synchronous digital hierarchy) by means of parity evaluation. This requires the splitting-up and reconstitution of the SDH signal. Specific signal processing devices, such as multiplexers and demultiplexers, which are not needed for repetition of transmission signals as such, are required for this purpose, which causes a considerable power loss. In the repeater (RE) according to the invention, the transmission error probability is determined by comparison of a known word in the header part of an STM-N signal with a reference word. The transmission error probability is derived from the result of the comparison and fed via an error line (FL) to a central station. The transmission error probability can be transmitted in an STM-N signal in that it is effected via a repeater complying with CCITT Recommendation G.958 by using, for example, the service channel. <IMAGE>

Abstract: ABSTRACT           A torque wrench (10) in which the torquing forces are applied to the article torqued equally and oppositely in a diametrically opposed manner.  The body of the wrench comprises a two-part metal frame (14, 16) which permits the wrench to be significantly lighter than prior art wrenches.  The applied forces are pro-vided by four hydraulic cylinders (30) mounted in a frame, equally spaced about a central opening in which the member to be torqued is gripped.  The fluid power cylinders apply force to the legs (42) of a rotatable drive means (34) which, in turn, rotates the member torqued.  In order to provide rotation in both direc-tions, each cylinder (30) of the wrench is pivotable to engage two adjacent legs (42) of the drive means (34) and thereby permit the drive means to selectively rotate in opposite directions.  The hydraulic wrench according to the invention is provided with a self-contained hyd-raulic system (32) in order to create a completely port-able unit which is generally free from hydraulic contami-nation.

Title: Multi-mode input/output circuit and module, and process control system using same
Inventor: BILANE GLENN B
IPC: G05B19/042
Filed: 1992-12-11
Abstract: ABSTRACT OF THE DISCLOSURE      A universal I/O circuit is provided to interface a control computer system with remote sensor transmitters which produce outputs representing one or more process variables and with remote controlled devices which control process variables.  The circuit uses a pair of terminals in series combination with an electrically-controllable variable resistance device and a load means, across which series combination a supply voltage is applied.  A microcomputer controls the resistance of the variable resistance device, as well as of associated circuitry, to operate them appropriately to receive current inputs from the remote transmitters or to supply current or voltage outputs to the remote controlled device; in any of these cases, the remote controlled device or remote transmitter is connected directly to the two terminals.      The variable-resistance device is preferably a transistor, and the load means a resistor.  A third terminal may also be provided to receive voltage inputs from a remote device, which voltage input is applied between the third terminal and the terminal which is connected to the load means; the microcomputer again controls the I/O circuit to provide appropriate operation.  Either continuous analog or discrete on-off signals may be accommodated, and two such I/O circuits may be jumpered together at their I/O terminals to accommodate bipolar signals when, as is preferred, the individual I/O circuits are otherwise galvanically isolated from each other.

Title: Polymerization of vinyl chloride
Inventor: SEIICHI MASUKO
IPC: C09D161/12
Filed: 1990-12-28
Abstract: ABSTRACT In a novel method of homo- or copolymerization of vinyl chloride, a specified coating agent is applied on the surfaces of the portions which will become into contact with the vinyl chloride monomer during the polymerization process. The coating agent is in a form of an aqueous solution of a modified condensation product of phenol and aldehyde, the pH of the solution being adjusted in a range that the product is dissolved at an ambient temperature upon coating of the solution and separates out of the solution upon being heated on the surfaces.  The wall surface of the polymerization tank and the like is then coated with a thin film of the coating agent having a uniform thickness and being strongly adhered to the wall surface, thereby providing an excellent effect of preventing adhesion of the product polymer to the wall surface.

Title: Triple orthogonally interleaved error correction system
Inventor: RHINES DON S
IPC: H03M13/29
Filed: 1993-01-13
Abstract: The detection and correction of errors in digital data transmitted by or stored  in a media channel  is provided  by  processing  the  data  through  a  triple orthogonally interleaved error correction system.  On the transmit/store side of the system, the data is encoded three times prior to placement in the media channel with two different interleaving steps performed between the encoding steps.  The first interleave is an orthogonal row shuffling interleave that provides enhanced protection against burst errors.  On the receive/play back side, the data is decoded and deinterleaved, with included errors detected and corrected to enable recovery of the original data.  To enhance the error correction, a circuit is used for generating a symbol accurate error flag identifying symbols  containing  errors  thereby  allowing  the  error correcting decoders to focus on and correct the data.

Filed: 1992-08-06
Abstract: Abstract In a film type battery comprising a generating element which is  formed  by  laminating  a  negative  active  material,  an electrolyte and a positive active material into a layer shape (1, 2, 3), terminal plates (5, 6) which are installed on and under the generating element and serve also as a current collector and a container, and a frame-shaped sealing material (4) which is installed on peripheral edges of the terminal plates, seals the generating element in between the both terminal plates and insulates one terminal plate from the other, the sealing material is improved.  For example, the sealing material is formed into a vertical-type multi-layer structure,  in which at least one layer is composed of a layer (41, 42) comprising metal and the other layer (43) is composed of an electric insulator.  Thereby, a mechanical strength of the sealing material or a battery becomes  large  and  the  battery  becomes  hard  to  be  bent.          Accordingly, an ingress of atmosphere from a sealing portion and a  leakage  of  electrolyte  therefrom  can  be  prevented,  a deterioration of battery performance can be prevented, and a long-term reliability can be improved.

Patent CA-2106351-A1 (CA)
Inventor: GAFFNEY THOMAS R
IPC: B01J20/02
Filed: 1993-09-16
Abstract: The present invention is directed to adsorptive separation of nitrogen with active adsorbent phases with high N2 capacity and high heats of adsorption when diluted with inert material at levels ranging from 5% to 80%. The presence of diluent reduces the temperature swings in the adsorbent bed, which increases the utilizable effective N2 working capacity and decreases the relative amount of O2 left unrecovered on the active adsorbent phase. The net result is equal or better process performance allowing utilization of a lower amount of active adsorbent phase. Use of a diluent having a higher heat capacity than that of the active adsorbent phase increases these benefits, but dilution effects are beneficial even for diluents with heat capacities equal to or lower than that of the active adsorbent phase.
