Patent CA-2042920-C (CA)
Title: Polydextrose compositions
Inventor: BUNICK FRANK J
IPC: A23L29/00
Filed: 1991-05-21
Granted: 2002-01-08
Abstract: A polydextrose composition that is substantially free of bitter tasting and color causing compounds is useful as a bulking agent in the incorporation of low calorie foods. In particular, the bulking agent may be combined with high intensity sweeteners as a replacement for sugar in foods so as to lower their calories without detracting from their texture and mouthfeel. Commercially available polydextrose that otherwise contains acidic compounds that cause bitter tastes and contribute to off colors thereby deterring its use in many food applications is purified through modified ion exchange column chromatography.

Title: Resource reallocation for flow-enforced user traffic
Inventor: CHARVILLAT ERIC
IPC: H04L47/765
Filed: 1992-06-29
Granted: 1997-10-28
Abstract: In a packet (ATM) network, a source node at the entry of the network is responsive to a connection request from a user terminal for invoking a CAC (call admission control) algorithm to accept or reject the request depending on the amount of resource requested by the user, and allocates a portion of a free bandwidth resource exclusively to the user for the duration of the call according to established contract parameter values. Each node of the network responds to a reallocation request from the user for transmitting a copy of the request to a downstream node to elicit an acceptance message therefrom, and reserving a portion of a pool bandwidth resource and invoking the CAC algorithm to additionally reserve a portion of the free bandwidth resource. The node proceeds to allocate the reserved pool bandwidth to the user in response to the acceptance message indicating that the same amount of the reserved pool bandwidth is available in the downstream node. The allocation of the pool bandwidth is temporary. When a portion of the free bandwidth resource is reserved using the CAC algorithm, this portion is exclusively allocated to the user until the end of the call and the temporarily allocated pool bandwidth is returned to the pool resource for other users.

Patent CA-2081761-C (CA)
Inventor: KENWRIGHT ERIC THOMAS
IPC: F16L33/02
Filed: 1992-10-29
Granted: 1999-06-01
Abstract: An open clamp structure, especially an earless clamp structure with overlapping inner and outer clamping band portions adapted to be mechanically interconnected; the clamp structure can be tightened about the object to be fastened by the application of a tightening tool at tool-engaging surfaces in these band portions; the tool-engaging surfaces are thereby so constructed and arranged that over-torquing during tightening is precluded.  Savings in band material can be realized by the particular arrangement of the mechanical connection of the inner and outer band portions which also permits an efficient preassembly.

Title: Biphasic release formulations for lipophilic drugs
Inventor: BARNWELL STEPHEN G
IPC: A61K9/48
Filed: 1991-10-18
Granted: 2002-01-29
Abstract: A pharmaceutical formulation comprises:   (a) a C12-C24 fatty acid, which may be saturated or mono- or poly-unsaturated, such as oleic or linoleic acid;   and (b) a generally lipophilic pharmaceutically active substance.    A portion of the C12-C24 fatty acid is formulated for non-sustained release on non-parenteral administration and a portion of the C12-C24 fatty acid and at least a portion of the pharmaceutically active substance are formulated for sustained release on non-parenteral administration.      The pharmaceutically active substance may be a cardiovascular drug such as propranolol, verapamil, nifedipine, diltiazem, metoprolol, nicardipine or labetolol. Such formulations promote absorbtion redistribution of the active substance(s) from the hepatic portal blood supply to the lymphatic system, thereby avoiding first-pass liver metabolism.    Formulations of this type will have a predictable dose response in patients, achieved with a lower chemical load, with which therapeutic efficacy is maintained.

Title: Shelter cone for protecting seeds and seedlings
Inventor: SPENCER HENRY ANDERSON
IPC: A01G13/04
Filed: 1993-06-17
Granted: 1996-08-27
Abstract: An improved, light-transmitting, plastic shelter cone or terrarium is provided for the germination of seed and growth of seedlings. The cone has a lower soil-engaging flange at its base and a vent opening at its top. The vent opening is covered with a hinged flap which is an integral part of the cone and to which seed may be secured using a water soluble adhesive. When placed in the field, the flap is pressed down into engagement with sidewall indentations which hold the flap and seed in a generally vertical orientation within the cone chamber. Stiffening ribs are formed in the cone wall, protruding outwardly and forming grooves within. Seed may be secured within a groove with water soluble adhesive. When the cone is used, rainfall will dissolve the adhesive, whereby the seed may drop to the soil below. Latching the flap ensures that it does not return to block the vent opening.          Preferably, the plastic is sunlight degradable and is further colored translucent red to modify the transmitted light.
