Patent CA-2093791-A1 (CA)
Title: Purification of hydrogen peroxide
Inventor: MILLAR MALCOLM H
IPC: B01J47/10
Filed: 1991-10-02
Abstract: 2093791 9206918 PCTABS00012 Purification of aqueous hydrogen peroxide solutions using conventional ion-exchange techniques can result in the hydrogen peroxide decomposing explosively. Much safer processes are obtained by restricting the contact between the resin bed and the hydrogen peroxide solution to a very short contact time, by employing a treatment chamber that is vented to the atmosphere and also by slurrying the resin bed. The bed is conveniently retained on a mesh that acts as a filter (13) preferably conical having an aperture (17) at its apex through which is introduced a small fraction of the solution countercurrent (10) to the main solution flow (9) in order to slurry the bed (19). The solution can be recycled through the same bed or a plurality of beds. Very high purification can be achieved and combined with improved safety of operation.

Title: Process for the preparation of alkyl polyglycosides
Inventor: BALZER DIETER
IPC: C09K23/56
Filed: 1993-05-07
Abstract: ABSTRACT         A process for the preparation of C8-C24-alkyl poly-glycosides  from saccharides and alcohols is disclosed.  The process comprises a step of glycosylation of a saccharide with a short-chain alcohol having 1 to 6 carbon atoms, followed by a step of transglycosylation of the alkyl glycosides so obtained with long-chain alcohols containing 8 to 24 carbon atoms.  The process according to the invention is carried out in the presence of phosphorus-containing mineral acids, their alkali metal salts or their alkaline earth metal salts.  Compared with similar products known in the prior art, the products prepared according to the process of the invention have improved colour and water miscibility.  They are useful as surface-active agents, particularly for cosmetic applications.

Title: Shadow Boundary Process for the Continuous Radiant Cure of Composites
Inventor: SMITH CHARLES R
IPC: E01F15/04
Filed: 1992-05-21
Abstract: A method for the production of fiber reinforced plastic composites (18), in which a continuously moving array of fibers (10) is impregnated with resin and fast cured as it passes through a shadow boundary (17) created by a source of radiant energy (16) such as ultraviolet light.

Title: Frequency hopping spread sprectrum data communications system
Inventor: AVERY JOHN W
IPC: H04W28/04
Filed: 1993-10-14
Abstract: "FREQUENCY HOPPING SPREAD SPECTRUM DATA          COMMUNICATIONS SYSTEM"     Abstract of the Disclosure A frequency hopping spread spectrum wireless data communications network is disclosed. Time mark frames are transmitted by each base station at a regular cadence and each time mark frame contains all information necessary to determine the hopping sequence of channels, a sub-set of possible channels in use, and the particular channel upon which the time mark was transmitted. Receipt of the time mark resynchronizes a slot clock that is used by the wireless terminals in implementing a media access protocol With defined synchronous time slots. The base station to roaming terminal radio link is half duplex. Each base station broadcasts an end-of-message frame during a hop period that indicates that it has no more data to send during that hop. If there are no outbound messages a roaming terminal needs to send, it puts its receiver in a low power mode until the next hop time approaches. Look ahead acquisition of the hopping sequence for a nearby base station when the received signal level for the current base station drops is also disclosed.

Title: Authenticating label and it's manufacture
Inventor: ELDRIDGE ROBERT H
IPC: B32B7/12
Filed: 1994-04-05
Abstract: An authenticating label is provided by adhering a substantially transparent peel strength adhesive to the underside of a protective layer, adhering an authenticating representation which will disintegrate if unsupported, to the underside of the peel strength adhesive layer, adhering a bonding material to the underside of the authenticating representation, and adhering a pressure sensitive adhesive layer to the bonding material and any uncovered underside of the peel strength adhesive layer. The bonding material bonds the pressure sensitive adhesive layer to the authenticating representation in a relatively stronger manner than that by which the peel strength adhesive layer adheres thereto, and the peel strength adhesive layer material, the bonding material, and the pressure sensitive adhesive layer material are selected to have similar melting and solubility characteristics, thereby rendering it very difficult if not impossible for the authenticating representation to be removed intact from an article once it has been applied thereto by the pressure sensitive adhesive.
