Title: Artificial digital neuron, neuron network and network algorithm
Inventor: AUSTIN KENNETH
IPC: G06G7/60
Filed: 1993-03-12
Abstract: IMPROVED ARTIFICIAL DIGITAL NEURON, NEURON NETWORK AND   NETWORK ALGORITHM    ABSTRACT            The invention relates to an improved artificial digital neuron, an enhanced artificial neural network architecture together with a reduced training neural network training algorithm.  The digital neuron comprises an n bit input one bit output device utilising a random access memory having 2n locations of one bit each.  The neuron is programmed by the network training algorithm with the neuron fire state (on or off) in accordance with the synaptic weights allocated to the input code combination pattern for that neuron within the neural network.  The digital neuron operates as a look-up table device deriving the neuron firing state, for each n bit digital code pattern applied to its input paths, from the random access memory location identified by the digital code pattern.  The synaptic weights allocated to each digital code pattern for a particular neuron in the network cause the neuron to provide as an input correlation function or an interconnect function.  The network architecture is based upon digital neurons providing either correlation or interconnection functions allowing a reduced interconnection arrangement where the output of each neuron in the input and hidden layers is connected only to an input path of a corresponding or immediately above or below neuron in the next layer.  The training algorithm maps each pattern (as a function or interconnect) into neurons that lie on the path between a positive input (1) and the network output.

Title: Processing of yeast refuse and resulting product
Inventor: GREENSHIELDS RODERICK
IPC: A23L33/20
Filed: 1991-10-17
Abstract: Yeast refuse having a solids content not exceeding 20 % by weight is digested with a food grade alkaline salt such as sodi-um bicarbonate, whole cells are separated from the extracted refuse so as to produce a material rich in disrupted ceU. walls which is then treated with an alkaline extraction agent and bleached either before or after the separation step, followed by lowering the pH of said bleached material using a food grade acid such as dilute hydrochloric acid. The product comprises a yeast beta-glucan which is substantially free of yeast cells, and which predominantly comprises a multiplicity of yeast ghosts or shells comprising substantially uncollapsed yeast cell walls. The yeast ghosts or shells contain a substantially lower quantity of yeast cell contents relative to the whole cells of the yeast refuse.

Title: Cosmetic composition and process for making it
Inventor: GOUGH ANTHONY D
IPC: A61K8/00
Filed: 1993-04-20
Abstract: Cosmetic compositions comprising an emulsion, preferably an aqueous emulsion, including at least one cosmetic resin material, e.g. a hydrocarbon resin such as polyisobutylene, are made by direct emulsification of the resin without a solvent or carrier therefor. The direct emulsification may be achieved by a special mixing regime, with particular emulsifiers. The absence of solvent or carrier for the resin material avoids product thinning and gives several manufacturing and processing advantages.

Patent CA-2106540-A1 (CA)
Inventor: VANCHA JOHN
IPC: G01V8/12
Filed: 1993-09-20
Abstract: A system is disclosed for determining and indicating calcification in a clear water conduit. The present invention directly determines calcification and indicates cleaning of the clear water conduit. An infrared transmitting circuit emits an infrared pulse through the clear conduit. As long as calcification has not formed on the conduit to block the infrared pulse, a phototransistor or infrared receiving circuit receives the infrared pulse. When calcification has formed in the clear conduit enough to block the emitted infrared pulse, the receiving circuit determines that calcification has occurred and provides a visual indication to a user that the conduit needs cleaning.

Title: Nitric oxide synthesis inhibitors for potentiating the action of pressor agents in certain hypotensive patients
Inventor: GROSS STEVEN S
IPC: A61K31/223
Filed: 1992-07-01
Abstract: A method for treatment of an animal for systemic hypotension induced by internal nitric oxide production caused by endotoxin or cytokines. The method involves administering an .alpha.1 adrenergic agonist and an amount of an inhibitor of nitric oxide formation from arginine restoring vascular contractile sensitivity to $(a)1 adrenergic agonists. Preferable NG-substituted arginine (having at least one hydrogen on a guanidino amino group replaced by another atomic or molecular species). The inhibitor is administered to an animal having such induced systemic hypotension.  Arginine derivative inhibitors are preferably of the L configuration and include pharmaceutically acceptable addition salts. Treatment of systemic hypotension in a patient which has been induced by chemotherapy with biologic response modifiers such as tumor necrosis factor or interleukin-2 may be likewise accomplished. Treatment of an animal for systemic hypotension induced by endotoxin, or other bacterial toxins, e.g., septic shock, may also be accomplished by treatment with .alpha.1 adrenergic agonists and an inhibitor such as an arginine derivative, restoring vascular contractile sensitivity to the .alpha.1 adrenergic agonists.
Patent CA-2111808-A1 (CA)
Inventor: ANDERSON DANA Z
IPC: G02B6/02
Filed: 1993-12-17
Abstract: The invention involves a method for making Bragg gratings in glass optical fibers, or other glass optical waveguides (10), which is relatively insensitive to perturbations in the actinic light used for processing. This method is suitable for mass production and lends itself well to the manufacturing environment. The inventive method involves first providing an optical phase grating (20). An interference pattern is generated by impinging a single light beam (30) on the grating. The optical waveguide to be processed is exposed to this interference pattern, leading to the formation of a Bragg grating in the waveguide.

Abstract: A method of making a thermoplastic laminate includes the steps of extruding a tubular polymeric film; collapsing the extruded film to form a layflat film; slitting the edges of the collapsed film to form two plies; taking up both plies of the slit film onto a single take up roll to form a double wound film with two plies, the film having first and second outside surfaces; corona treating the first outside surface of the double wound film; applying a varnish to the treated surface; printing the varnished surface; corona treating the second outside surface of the double ground film; and taking up the printed film onto a wind-up roll such that the treated printed surface of one ply of the film in the roll bonds to the treated second outside surface on an adjacent wind in the roll, thereby forming a laminate. Alternatively, two separate films may be taken up on a take up roll to form a double wound film, and processed as described. The result is a trap printed laminate with good machinability and other properties.
