Patent CA-2109034-A1 (CA)
Title: Washerless pressure balancing valve
Inventor: CLARE MANAMOHAN
IPC: F16K11/074
Filed: 1993-10-21
Abstract: ABSTRACT     The invention relates to a shower control valve assembly which includes a casing mountable in a wall with inlets for hot and cold water. A cartridge is insertable into the casing in one of two orientations so that the hot water inlet of the cartridge can be aligned with either one of the casing inlets, depending on which one is the hot water inlet. The casing has two outlets, one for the shower and the other for the tub. There is an integral bypass which takes water from the tub outlet to the shower outlet upon activation of a diverter valve. The cartridge is of the pressure and temperature balancing type, with water of the desired temperature flowing to the tub outlet and then to the tub or shower as desired. The cartridge uses a rotatable mixing valve disc having arcuate ports therethrough for hot and cold water, each port being alignable with a corresponding passage in the cartridge that communicates with an inlet chamber for water of the appropriate temperature. The thickness of the valve disc at each port diminishes from a maximum to a minimum and a cam surface is provided adjacent each port. Within each passage is an axially movable seat member that has an annular surface in constant contact with the cam surface and an opposite annular surface that is sealable against an O-ring held by a snap seal member to prevent water flow through the seat member and the mixing valve disc. The snap seal member allows water flow therepast and is biased towards the disc, but when the axially movable seat member is in sealing contact with the O-ring, no water can pass to or through the valve disc. With this configuration wear is minimized and it is not necessary to use toxic lubricants to maintain smooth action of the valve disc.
Patent CA-2109179-A1 (CA)
Title: Process for bleaching of lignocellulose-containing pulp
Inventor: HOLTINGER LILLEMOR
IPC: D21C9/10
Filed: 1993-10-25
Abstract: Abstract The present invention relates to a process for bleaching of lignocellulose-containing pulp, in which the pulp is treat-ed at a pH between about 1 and about 7 in the presence of a magnesium compound, whereupon the pulp is washed and subse-quently bleached with a peroxide-containing compound. The ini-tial treatment removes from the pulp those trace metal ions that have a negative effect on the subsequent bleaching with a peroxide-containing compound. Owing to the presence of mag-nesium ions in dissolved form during the initial treatment, the magnesium ions are retained in those positions in the pulp where they have a particularly positive effect on the effec-tiveness of the bleaching stage.

Title: Hay feeder for livestock
Inventor: DYSON KAREN
IPC: A01K5/01
Filed: 1994-02-18
Abstract: ABSTRACT      A resiliently flexible hay feeder for livestock.  The feeder is made from a flexible plastic material such as polyethylene so that the complete feeder responds to stresses with flexibility rather than rigidity.  The feeder initially deforms but resiliently resumes its original shape when stressful forces are removed.  The bale feeder also includes a plurality of bale centering springs attached around the peripheral edge of the feeder in order to maintain the hay a fixed distance away from the peripheral edge of the feeder and thus reduce waste by allowing hay that falls from an animal's mouth to return into the feeder to be eaten later, instead of being trampled and wasted. The feeder is made up of component parts which are assembled after shipment.  This enables the feeder to not only be shipped at a reduced cost via parcel post but also permits a broken feeder to be easily repaired by simply replacing the broken piece with a new piece.

Title: A method for combustion of hydrocarbons
Inventor: LYNUM STEINAR
IPC: F16L55/18
Filed: 1992-12-11
Abstract: In order to enrich natural gas or other hydrocarbon gases with hydrogen, thus reducing the carbon content and thereby achieving a reduction or elimination of the discharge of carbon dioxide during combustion of the gases, a pyrolytic process is conducted in the feed stream for the natural gases or hydrocarbon gases which are to be burned. The gas is passed through a reactor in which it is decomposed at least partially into a carbon constituent and a hydrogen constituent. The carbon constituent is removed to a desired level. Any remaining constituent together with the hydrogen constituent is conveyed to the combustion process while the removed carbon constituent is conveyed out of the process for separate application. The pyrolytic process can be carried out on the entire stream or only on a partial stream.

Title: Methods of treating inflammatory dermatoses
Inventor: KLIGMAN ALBERT M
IPC: A61P17/00
Filed: 1993-01-29
Abstract: Inflammatory dermatoses are controlled and cleared by topical application to the affected areas of the skin of a composition containing both a corticosteroid and a retinoid. The combined therapy is more effective than either active ingredient alone and is particularly effective for chronic dermatoses which are or have become resistant to corticosteroid treatment alone. After clearing has been obtained with once or twice daily applications of the corticosteroid-retinoid composition, usually after several weeks, clearance can be maintained by less frequent application or lower concentrations of the composition or by application of only one of the corticosteroid or retinoid, less potent corticosteroids, or other non-steroidal therapies, depending upon the particular dermatosis being treated.

Title: Peptides that mimic gp120 hiv epitope
Inventor: BUTLER PETER J G
IPC: C07K16/00
Filed: 1993-07-16
Abstract: The invention provides a molecule comprising a peptide having the amino acid sequence lysine-proline-cysteine-valine-lysine-leucine-threonine-proline-leucine-cysteine-valine (Seq.Id.No.1), wherein each cysteine resi-due is disulphide bridged to a further cysteine residue or is derivatised to simulate part of a disulphide bond, or functionally equivalent variants of such a peptide which mimic the immunogenic behaviour of an epitope of gp120 of HIV env. The sequence is highly conserved, being total-ly conserved in all listed isolates of HIV-1 and HIV-2, and undergoes only minor changes in isolates of SIV. With each cysteine residue contributing to a respective disulphide bridge (actual or simulated by suitable deriva-tisation), the molecule accurately mimics behaviour of the corresponding sequence of gp120 and elicits an immune response. The molecule can thus be used as the basis of a potential vaccine against AIDS and AIDS related condi-tions, and may find use in the treatment of AIDS and re-lated conditions.
