Patent CA-2098305-A1 (CA)
Title: Lectins in probiosis
Inventor: PUSZTAI ARPAD J
IPC: A61P31/00
Filed: 1991-12-16
Abstract: Many microorganisms (such as bacteria) are capable of causing disease or other conditions in a host animal by attaching to host cellular receptors by means of sugar-specific lectins or adhesins.  Even non-pathogenic bacteria may give rise to, for example, non-specific colitis, by this means. Plant lectins, such as Galanthus nivalis agglutinin (GNA), can be administered to compete with, for example. bacterial adhesins for the sugar-containing receptors, thereby treating or preventing the bacterially-mediated infection. Such lectins can also be fed to livestock to keep down infectin and present a preferable alternative to the routine use of antibiotics for this purpose.

Title: Reduced polydextrose
Inventor: BORDEN GEORGE W
IPC: A23L27/30
Filed: 1992-01-03
Abstract: A polydextrose having improved color, flavor and decreased reactivity toward food ingredients having amine functionality. The polydextrose comprises a water-soluble highly branched polydextrose having been prepared by a process which comprises melting dextrose in the presence of a food-acceptable acid catalyst. The improved polydextrose of this invention has substantially no reducing glucose groups. Another aspect of this invention is directed to a method of making the above-described improved polydextrose which comprises exposing unimproved polydextrose to an environment capable of chemically transforming the reducing glucose groups contained in the unimproved polydextrose, thereby substantially eliminating their reducing properties. An improved polymaltose prepared by heating maltose in the presence of a food-acceptable acid catalyst and chemically transforming the reducing glucose groups contained in the polymaltose, thereby eliminating their reducing properties, is also described.

Title: Wall Water Hydrant Having Backflow and Back Siphonage Preventor
Inventor: ALMASY LAWRENCE
IPC: E03B9/02
Filed: 1993-11-25
Abstract: A wall mounted water hydrant (10) has an elongated hollow housing (12) with water inlet and outlet ends, and a center axis; an inlet valve in the housing adjacent to the inlet end, including a valve seat (39) and a valve body (42); a water outlet port (24) in the housing (12) adjacent to its outlet end; a valve operating rod (30) in the housing (12) with its inner end secured to the valve body (42) and extending along the center axis to the outlet end of said housing (12), terminating in an outer end; a handle (28) attached to the rod outer end, which when rotated in one direction closes the valve body (42) against the valve seat (39), and in the other opposite direction moves the valve body (42) away from the seat (39), thus allowing pressurized water from the inlet to flow downstream through the housing (12) and outlet port (24); and a backflow preventor (44) secured to the valve downstream from its seat (39).  The elastomeric backflow preventor (44) has a bell shape comprising a cylindrical body (46) smaller than the interior of the housing and thin flexible side walls (48 and 51) extending from the body outwardly and downstream to end in a lip portion (52) which normally engages the interior walls of the housing (12).  The construction of the preventor (44) permits it to deflect toward the axis of the housing (12) when water is flowing in a downstream direction and to engage the interior surface of the housing if backpressure urges water to flow in an upstream direction, thus sealing the valve means against backflow.

Patent CA-2114670-A1 (CA)
Inventor: LABONTE NELSON
IPC: C10L11/04
Filed: 1994-02-01
Abstract: Dans les articles servant à allumer un feu, la pratique courante était de se servir de journaux, d'écorce de bouleaux, de bois fendu en bois d'allumage, additionné souvent d'un activant pétrolier. On sait que l'efficacité de combustion des dispositifs d'allumage déjà connus résulte non seulement de leur constitution mais également de la façon dont ceux-ci sont disposés sur la substance à allumer afin de permettre un jeu d'air pour l'entretien de la flamme. Dans la présente invention, le dispositif d'allumage qui est un allume-feu est composé de plusieurs feuilles de carton ondulé, superposées les unes sur les autres et retenues entr'elles par de la colle pour ainsi former une briquette, laquelle est ensuite imprégnée de paraffine, de cire ou de gras animal ou végétal. L'utilité et la distinction de la présente invention résulte du fait que la disposition de ce dispositif d'allumage sur la substance à allumer importe peu puisque le jeu d'air est permis grâce à la constitution même du dispositif d'allumage. En effet, les alvéoles du carton ondulé imprégnées permettent ce jeu d'air et par conséquent, procure une flamme soutenue. Il permet un allumage rapide et soutenu, dans un minimum d'espace.  Egalement, le dispositif d'allumage peut occasionnellement être muni d'allumettes paraffinées. Dans ce cas, il s'agit d'un allume-feu de survie qui permet qu'une allumette soit toujours à la disposition de son utilisateur.

Abstract: In this lift installation for zonal operation with immediate allocation of zone calls, the passenger traffic between at least one main stopping place (HH) and zones in a high building is managed by a lift installation (ABC) consisting for example of three lifts (A; B; C). The passenger traffic filling the building and arriving at the main stopping place (HH) is symbolised by arrows (P0; P1 to Pn) pointing to the lift group (ABC). The passenger traffic leaving the building and arriving at the main stopping place (HH) is symbolised by arrows (Pa) pointing away from the lift group (ABC). Each lift user filling the building passes one gateway (G0; G1 to Gn), which is associated with a zone and in which a sensor (S0; S1 to Sn) registers the lift user. Through the choice of the appropriate gateway (G0; G1 to Gn), the lift user informs the lift control of his desired zone without manual actuation of a call-registering equipment. The signals of the sensors (S0; S1 to Sn) are passed on to the control equipments of the lifts (A; B; C), which in turn inform the lift user before leaving the gateway (G0; G1 to Gn) of the respectively allocated lift by means of an indicating equipment (D0; D1 to Dn).

Abstract: Abstract The invention relates to a process for preparing aqueous solutions and gels of chitosan, in which chitosan and an acid chelating agent are dissolved in water.        Such   solutions   can   have   their  viscosity drastically increased or be converted into high-viscosity gels, by adding salts of polyvalent metals and acids in which chitosan is only moderately soluble or insoluble.        From such solutions, salt-like chitosan-chelating agent adducts can be obtained by removal of water or by precipitation using an organic solvent.
