Title: Pyridinium derivatives and pharmaceutical compositions containing them
Inventor: AMITAI GABRIEL
IPC: A61K31/00
Filed: 1996-08-29
Abstract: A series of carbamates based on the structure of pyridostigmine (PYR) were synthesized and evaluated as potential drugs for the treatment of cognitive impairments associated with cholinergic perturbance such as in Alzheimer's disease. These compounds were examined for their cholinesterase inhibition, pharmacokinetics, acute toxicity, lipophilicity, reversal of scopolamine induced memory impairment in rats (passive avoidance) and analgesia in mice.  These compounds include N-alkyl-PYR and various sugar-N-alkyl-PYR conjugates, being 3-position substituted pyridinium derivatives of general formula (I).  Some of the new compounds are less toxic than PYR in rats and may serve for the treatment of other CNS-related diseases such as stroke and PNS-diseases such as: mysthenia gravis, glaucoma, neurogenic urinary bladder, neuralgic pains and as a pretreatment of organophosphorus intoxication.

Inventor: MCLOUGHLIN IAN VINCE
IPC: G10L25/15
Filed: 1998-04-21
Abstract: A speech communication system comprises a receiving unit 14 which receives speech data and uses that data to output speech 15.  The characteristics of the speech received by the decoding unit are altered by a processing unit 10 based upon an analysis of the listener's current background noise before the speech is output to enhance its intelligibility to a listener.  An analysis unit 12 determines the type and level of the background noise by use of a microphone 13.  A decision unit 11 then determines whether the speech currently being received and replayed would be intelligible to an average listener in the current background noise.  If the decision unit 11 determines that the speech is readily intelligible then no processing is necessary and the processing unit 10 does not alter the speech which has been passed to it.  However, if the decision unit 11 determines that the speech would be unintelligible, then processing is necessary and the processing unit 10 alters the speech before passing it to the output to make the speech more intelligible.  A method of operating the apparatus is also described.  In a particularly preferred embodiment, the speech characteristics are altered by altering line spectral pair data representing the speech.

Title: Reclosable fastener assembly
Inventor: PORCHIA JOSE
IPC: A44B19/26
Filed: 1997-06-30
Abstract: A reclosable fastener assembly having two interlocking profiles with uppermost closure elements and bottommost closure elements and a slider for moving between a closed position and an open position along the profiles in straddling relation. The slider has a top and side walls depending from opposite sides of the top for receiving the profiles therebetween. The side walls extend downward from the top to a point at or below the profiles, and the side walls extend from a separating end of the slider to a pinching end.  The side walls have a greater spacing at the separating end than at the pinching end, but close enough at the pinching end to press the first and second profiles into an interlocked relationship as the slider is moved toward the closed position. The slider has a separating leg depending from the top between the first and second side walls at the separating end of the slider.  The separating leg is inserted past at least one of the uppermost closure elements of the profiles, but not between the bottommost closure elements. In a second aspect, the fastener assembly includes means for holding the bottommost closure elements in interlocked relationship when the slider is in the closed position, such that the bottommost closure elements are in interlocked relationship throughout their entire length.
Patent CA-2237646-A1 (CA)
Inventor: HOLMES RALPH
IPC: G06F13/42
Filed: 1996-11-15
Abstract: A computer system has a plurality of non-compatible clients (102) and servers (110) selectively interconnected over a network (108), each client capable of initiating an application (124) in which a related compatible server is involved. Communication between the clients and servers involves a first registry process (104, 126) including the acceptance of application specific messages from a client, destined to a preselected server, and encapsulating them into standard registry specific messages (128). The routing of the messages is determined by a database that responds to a verb command, from a particular client, to provide routing data. Next, there is a translation of the registry specific messages into a preselected protocol (106, 130). A second registry process (104, 126) occurs at a distant end to restore the message, after passing through the network. The second registry accepts the translated messages and converts them from protocol format to the original application specific format for use by the preselected compatible server.

IPC: B65G41/00
Filed: 1998-10-20
Abstract: Highway safety regulations generally limit the length of trailers to 75'. Most large conveyors generally have two top folds, one at each end of the conveyor. This format facilitates a trailer which is balanced on a wheeled support both in an unfolded operative position and a folded towing position. The mono-fold trailer conveyor comprises: a main conveyor section having a feed end portion; one and only one folding discharge conveyor section having one end hingably attached to the main conveyor section and having a length exceeding one half of the length of the main conveyor section; and, a counterweight positioned on the feed end portion of the conveyor, necessitated by the otherwise unbalanced folding discharge conveyor section, and sized to stably maintain the discharge end of the conveyor in an elevated position when the conveyor is in an operative unfolded position. With a counterbalanced mono-fold trailer conveyor there is a substantially greater horizontal run between the wheeled support and the discharge end of the conveyor. This means that a mono-fold conveyor can stockpile a substantially greater volume of material than a bi-fold conveyor of similar length without being moved. The mono-fold trailer conveyor is also easier and less costly to manufacture; stronger; and safer to transport, setup and operate; than large trailer conveyors of conventional design.
