Abstract: A process for the continuous catalyst-free production of polyisocyanates by thermal decomposition of the N-substituted carbamic acid esters corresponding to the polyisocyanates, in which the carbamic acid esters to be decomposed, in the form of a 5 to 90% by weight solution in an inert high-boiling solvent, are heated to a temperature of 100 to 400°C and are subsequently introduced with expansion as a sidestream into a distillation column (4), in the sump of which a pressure of 0.001 to 5 bar and a temperature of 150 to 400°C are maintained so that the high boiler is kept boiling in the sump, and the decomposition products are simultaneously condensed continuously and selectively at the head of the distillation column. The high boiler, which optionally contains impurities, is continuously removed via the sump outlet in a quantity substantially corresponding to the quantity of high boiler introduced into 'the column as solvent for the carbamic acid ester.

Abstract: A vinylidene fluoride copolymer containing a carboxyl group or a carbonate group is formed by copolymerizing a monomer principally comprising vinylidene fluoride with a relatively small amount of an unsaturated dibasic acid monoester or vinylene carbonate.  The copolymer has a large adhesion to various substrates or fillers and is excellent in chemical resistance, so that it is useful as a basic substance constituting a binder, an adhesive, a paint, etc.  The copolymer is particularly effectively used as a binder for constituting an electrode for a non-aqueous solvent-type secondary battery together with an active substance, or an active substance and an electroconductive material, respectively in a particulate form.

Abstract: Measurement signals generated by detectors arranged in the transverse direction of a revolving paper machine roll are passed to a measurement signal reading unit installed preferably at the end of the roll. From the measurement signal reading unit, the signals are transmitted wirelessly further as telemeter signals to a reading unit placed outside the roll and connected to a PC or equivalent computer. In the measurement signal reading unit, a transponder is arranged into which an unique code is coded for each detector. The signals are processed in the entire measurement process as analog signals. In the transfer of the telemeter signals between the unit for reading and measurement of the detectors and the reading unit placed outside the roll, a substantially low transfer frequency of an order of from about 100 kHz to about 150 kHz is employed.

Title: Ds/cdma receiver for high-speed fading environment
Inventor: USHIROKAWA AKIHISA
IPC: H04J13/00
Filed: 1994-07-08
Granted: 2000-03-21
Abstract: A receiver is disclosed for a DS/CDMA communication system wherein a symbol is spread with a predetermined spread code to produce a DS/CDMA signal which is transmitted on a radio frequency carrier. The receiver includes an interference canceller for cancelling signals from undesired sources introduced to a signal received from a desired source using a feedback signal. A phase variation canceller is provided for cancelling a phase variation that occurs in an interval between successive symbols of the received signal. Both cancellers are connected in series. A decision circuit compares an input signal from the interference canceller or from the phase variation canceller with a threshold and produces an output representing one of two discrete values depending on whether it is higher or lower than the threshold. A correction circuit derives a correction signal from a signal produced by the interference canceller and applies it to the interference canceller as the feedback signal.
Patent CA-2128481-C (CA)

Granted: 1997-03-25
Abstract: A method is provided for establishing the location and orientation of the boundaries surrounding a subterranean reservoir and creating an image thereof. A conventional pressure test is performed on a well, establishing measures of the well's pressure response as defined by the rate of pressure change in the reservoir over time. Conventional techniques are used to determine measures of the radius of investigation. A calculated response for an infinite and radially extending well and the measured response are compared as a ratio.  Variation of the ratio from unity is indicative of the presence of a boundary and its magnitude is related to an angle-of-view.  The angle-of-view is related to the orientation of the boundary to the well.  By combining the angle-of-view and the radius of investigation, one can define vectors which extend from the well to locations on the boundary, thereby defining an image of the boundary.  In an alternate embodiment, the angle-of-view and radius of investigation can be applied in a converse manner to predict the pressure response of a well from a known set of boundaries.

Title: Intra-vehicular local area network and method of routing messages along it
Inventor: LUITJE WILLIAM V
IPC: B60R16/02
Filed: 1995-03-30
Granted: 2005-08-16
Abstract: Microcontrollers (10), e.g. those located within a vehicle or factory, are connected over a local area network (LAN) (25). The microcontrollers broadcast messages on the LAN tagged with an identifier (ID) which identifies the contents of the message, rather than a destination address. Microcontrollers on the network are provided with read only memory (ROM) (5) containing a table of message IDs and accompanying data, wherein the table address of each message ID was initially determined by applying a hash function to the ID. Upon receipt of a message, a microcontroller (10) applies the hash function to the message ID (Step 32). Using the result as a pointer into the table (Step 33), the microcontroller compares the message ID stored in that pointer location with the received message ID. If they are equal, the microcontroller performs a predetermined function (Step 34). If the message IDs are not equal, the message is ignored (Step 35).

Title: Osmotic devices having vapor-permeable coatings
Inventor: CUSSLER EDWARD L
IPC: C08G18/38
Filed: 1994-05-19
Granted: 1999-07-27
Abstract: An osmotic device that, following the imbibement of water vapor, provides for the controlled release of a beneficial agent to an aqueous environment. The device comprises a hydrophilic formulation including a beneficial agent, and if needed, an osmagent, surrounded by a wall. The wall is formed at least in part of a semipermeable hydrophobic membrane having an average pore size between about 0.1 .mu.m and 30 .mu.m. The pores are substantially filled with a gas phase. The hydrophobic membrane is permeable to water in the vapor phase and the hydrophobic membrane is impermeable to an aqueous medium at a pressure less than about 100 Pa. The beneficial agent is released, for example, by osmotic pumping or osmotic bursting upon imbibement of sufficient water vapor into the device core. These devices minimize imcompatibilities between the beneficial agent and ions (such as hydrogen or hydroxyl) or other dissolved or suspended materials in the aqueous medium, since contact between the beneficial agent and the aqueous medium does not occur until after the beneficial agent is released. This results from the semipermeable membrane's selective permeability for water vapor. In addition, the high water fluxes attendant with these vapor-permeable membranes facilitate the delivery of beneficial agents having low solubilities and the delivery of high dosages of beneficial agents.

Each end of the bond bar has a generally planar surface for engagement with the cable. A radially contractible clamping member is securable about the cable and about the planar surface of each bond bar end for securing the bond bar ends to the cable. The planar surface of each bond bar end includes a deflectable jacket skiving member which is deflectably movable from a first position in non-skiving engagement with the jacket of the cable to a second position in skiving engagement with the cable jacket upon the radial contraction of the clamping member. Such arrangement positionally confines and secures the bond bar with respect to the cable.
