Title: Cleaning device
Inventor: SAUNDERS DAVID H
IPC: B24C3/32
Filed: 1991-01-21
Abstract: ABSTRACT OF THE DISCLOSURE      A conduit (3) Can be cleaned by directing jets (10-14, 25) of abrasive mixture from a pressurized supply at its internal wall from a plurality of nozzles (7, 13, 16) which have no tangential component about the conduit axis.  Nozzles preferably includes two types, one type (7) which is inclined in one direction to the axis and another type (13) which is inclined in the opposite direction to the axis.  When the conduit (3) has an open end, the nozzles (7) directed away from that end are preferably closer to the end than those (13) directed towards it.  The density of abrasive mixture supplied by the different types of nozzles is arranged to be different by swirling the mixture and supplying different types of nozzles from different radii in the swirl output chamber (6).

Title: Polymerisation of olefinic-containing monomers employing anionic initiators
Inventor: SHEPHERD NEIL
IPC: C08F4/46
Filed: 1991-02-06
Abstract: Process for anionically polymerising a conjugated 1,3-diene monomer consists of contacting the monomer in an inert hydrocarbon solvent with a monofunctional silyl ether initiator of general formula R1R2R3Si-O-A-Li where R1 to R3 are independently selected from monovalent organic substituent groups and A is a short chain hydrocarbon bridging group, to yield a polydiene having a molecular weight of typically 1,000 - 10,000, a high 1.4 content of typically 90 % and a low polydispensity of typically 1.15. The reactive ends of the living polymer chains may be terminated with a reactive group such as hydroxyl by treating the polymer with ethylene oxide. Subsequent removal of the polymer's relatively unreactive silyl end groups by reaction with tetra-n-butylammonium fluoride produces a difunctional, chain-extendable, hydroxy-terminated polydiene useful as a rubbery binder prepolymer.

Abstract: TELEPHONE HANDSET CUSHION            Abstract of the Invention A cushion for application to a telephone handset. The cushion is made from a low density, high resiliency flexible  foam  to  make  the  telephone's  receiver  or transmitter more comfortable when pressed against the ear or mouth of the user.  The cushion has a main body which defines a funnel shaped channel for guiding sound between the handset and the user.  A diaphragm with sound ports completely covers the channel to dampen the sounds passing between the handset and the user.  The cushion is shaped to match the receiver or transmitter of the telephone handset and can include a groove to allow the cushion to hang  from a  wall mounted base  and tabs to  conduct electricity from recharging pins to rechargeable batteries in the handset.  A variety of coverings can be placed over the cushion for aesthetic or functional purposes.

Title: Switching excitation supply for argon-mercury discharge tubes
Inventor: ORENSTEIN EDWARD D
IPC: H05B41/285
Filed: 1991-11-13
Abstract: The present invention describes a method and apparatus for a high frequency switching gas discharge tube supply which suppresses or eliminates the "bubble effect" in gas discharge tubes containing neon or argon-mercury gas or other gases and which eliminates the migration of mercury or other migratory gases toward one electrode over time. To prevent mercury migration to one electrode over time within an argon-mercury gas discharge tube, a line frequency bias voltage is induced on the high frequency, high excitation voltage resulting in a gas discharge tube display which is uniform in intensity of light over the length of the tube.

Title: Gas permeable thrombo-resistant coatings and methods of manufacture
Inventor: WINTERS SUZANNE
IPC: A61M1/16
Filed: 1991-04-09
Abstract: The present invention is directed to thrombo-resistant coatings for use with gas permeable biomedical devices and implants. The coatings include a siloxane surface onto which a plurality of amine functional groups have been bonded. Covalently bonded to the amine functional groups are a plurality of poly(ethylene oxide) chains, such that a single poly(ethylene oxide) chain is bonded to a single amine functional group. A quantity of at least one bioactive molecule designed to counteract a specific blood-material incompatibility reaction is covalently bonded to the poly(ethylene oxide) chains, such that a single bioactive molecule is coupled to a single polyethylene oxide chain. The methods of manufacturing the present invention include preparing a material having a siloxane surface onto which a plurality of amine functional groups have been bonded. This is preferably achieved by plasma etching with ammonia gas. The amine-containing siloxane surface is reacted with poly(ethylene oxide) chains terminated with functional groups capable of reacting with the amine groups on the siloxane surface.  The material is then reacted with a solution of at least one bioactive molecule which counteracts a blood-material incompatibility reaction, such that a single bioactive molecule is coupled to a single poly(ethylene oxide) chain. The resulting siloxane surface is capable of resisting blood-material incompatibility reactions while maintaining high gas permeability.

Title: Reinforcing block for excavation work and method of construction thereof
Inventor: TATEYAMA MASARU
IPC: E02D5/74
Filed: 1993-01-28
Abstract: A novel method to construct a reinforcing block in an embankment is provided, wherein a core rod to which a protrusion is molded on the tip, is preset inside a hollow rotating shaft with drilling and agitating blades affixed around its circumference, but with the protrusion on the core rod exposed at the front of the shaft. This drilling and agitating shaft rotates and bores into the earth while simultaneously mixing the soil so agitated with a fixing agent; then at a specified depth, the rotating shaft is withdrawn leaving the core rod to remain anchored in the soil while the fixing agent continues to discharge from the end of the hollow rod; and when the hollow rod is completely removed, a reinforcing block is intact within the soil and the tail end of the core rod exposed on the surface of the banking is directly or indirectly affixed to this surface.      Alternatively a core rod with no protrusion can be inserted into the hollow rotating shaft which is first drilled into the embankment, such that the nose end of the said core rod is anchored into unagitated soil. In either case the reinforcing block so formed is comprised of an outer concentric tube of agitated soil mixed with a fixing agent molded around an inner concentric tube of reinforcing fixing agent molded around a core rod, and wherein the nose tip of the core penetrates into the unagitated soil beyond the end of the concentric reinforcing layers.
