Title: Heterogeneous catalyst for the production of acetic anhydride from methyl acetate
Inventor: RAMPRASAD DORAI
IPC: C07C51/56
Filed: 1997-05-14
Granted: 2000-09-05
Abstract: This invention relates to a process for producing acetic anhydride by the reaction of methyl acetate, carbon monoxide, and hydrogen at elevated temperatures and pressures in the presence of an alkyl halide and a heterogeneous, bifunctional catalyst that contains an insoluble polymer having pendant quaternized phosphine groups, some of which phosphine groups are ionically bonded to anionic Group VIII metal complexes, the remainder of the phosphine groups being bonded to iodide. In contrast to prior art processes, no accelerator (promoter) is necessary to achieve the catalytic reaction and the products are easily separated from the catalyst by filtration. The catalyst can be recycled for consecutive runs without loss in activity. Bifunctional catalysts for use in carbonylating dimethyl ether are also provided.

Title: Telephone communications network with enhanced signaling and call routing
Inventor: WHITTAKER RICHARD JONATHAN
IPC: H04M3/428
Filed: 1998-09-14
Granted: 2007-01-09
Abstract: Enhanced signaling and call routing is provided in a telephone communications network that includes a local telephone central office having a POTS line connection between a subscriber station and an access junction of the office. A voice path interfaces the access junction with a circuit switch for conventional dial-up voice call placement. Modem data calls, however, follow an access path from the junction as a physical switched connection terminated in layer 1 of a network data-switching matrix. The access path continues therefrom to a data switch which interfaces an Internet service provider. Interfacing the data and circuit switches, a network controller functions to selectively configure communications paths within the central office and between the office and network in response to commands originating at the subscriber station or incoming from other networks. Additional controller functions include blocking subscriber-originated traffic from the access path and queuing incoming network-side traffic when an Internet call is on hold, invoking a tear-down of the physical switched connection to free the access path for incoming and outgoing call attempts, converting PSTN-based voice signals to an IP-based voice format and transmitting any queued data to the subscriber station followed by restoration of normal data communications.

Abstract: A method and apparatus for helping health care professionals create clinical protocols or assist in direct entry of medical finding into a chart by intelligently prompting a health care professional with medical findings associated with at least one medical finding which has already been entered in the protocol, is disclosed (fig. 2). First of all, at least one medical finding for a patient is inputted into the system (10) wherein each findings is assigned a point of value for each diagnosis within a knowledge base (22).  A total number of points for each diagnosis is then totalled for all the findings which have been entered into the system (10). The possible diagnoses are then ranked in descending point total and predetermined plurality of the highest ranked diagnoses are selected. Once the higher ranked diagnoses have been selected, the health care professional is prompted with additional findings associated with the selected diagnoses which have not yet been inputted into the clinical protocol.

Granted: 2001-07-10
Abstract: The rotary cutting blade is mounted on a cutting machine which dispenses and cuts sheet material. The cutting machine includes a frame for supporting a cutting table top and a dispenser for supporting a roll of floor covering material. The rotary disk shaped cutting blade is mounted on a support block the frame below the table top for movement along a slot in the cutting table. A  cable or chain driven rotary drive drives the block back and forth and at the same time provides the rotary motion to the cutting disk in a direction such that a leading edge of the disk moves upwardly relative to the floor covering material as it cuts.  The chain passes over a sprocket on the block which carries a clutch so that the clutch slips when the block reaches one end of the slot and allows the chain to continue driving the rotary blade. A rotary sharpening disk is mounted at one end of the slot and is driven by the chain so as to rotate against the blade in a sharpening action while the block remains stationary.

Title: One-way actuation release mechanism for a system for applying medicament
Inventor: PY DANIEL
IPC: A61J1/06
Filed: 1998-12-17
Granted: 2007-10-30
Abstract: A medicament-dispensing system includes a cartridge for housing and actuating an accordion-like vial--dispenser for dispensing a calibrated amount of medicament by means of a single actuation motion which sequentially loads the vial-dispenser and dispenses the loaded medicament. The vial-dispenser has a front bellows portion, a rear bellows portion, an internal piston mechanism, a medicament storage chamber and a dosage cavity. The cartridge has a trigger mechanism which acts in concert with a notched lever and a wedge-shaped arm internally located in the cartridge to sequentially load the dosage cavity with medicament and discharge it. Depression of the trigger mechanism simultaneously extends, by means of the notched lever, the front bellows portion and compresses the rear bellows portion to load the dosage cavity with medicament. Once the notched lever has extended the front bellows portion a predetermined distance, the notched lever is disengaged from the front bellows portion by the wedge--shaped arm extending from the rear wall of the housing, thereby releasing the front and rear bellows portions, along with the internal piston mechanism, to return to original position and force the medicament from the dosage cavity via a nozzle of the vial-dispenser.

Granted: 2006-10-24
Abstract: Formulations have been developed for regional delivery of drugs, for example , into a cavity such as the pelvic region, peritoneal region, or directly on organs of interest. Regional delivery increases comfo rt and bioavailability of the drug, resulting in rapid and relatively high blood levels in the regions to be treated in the substantial absence of side effects due to the high levels required for efficacy following systemic delivery. In the preferred embodiment, these formulations consist o f drug micro or nanoparticles, which may be formed of drug alone or in combination with an excipient or polymeric carrier. The excipien t or polymer may be used to manipulate release rates and to increase adhesion to the affected region. The drug formulation can be applie d as a dried powder, a liquid suspension or dispersion, or as a topical ointment, creme, lotion, foam or suppository.
