Title: Compositions containing nucleic acids and ligands for therapeutic treatment
Inventor: SOSNOWSKI BARBARA A
IPC: A61K47/48
Filed: 1996-05-16
Abstract: Preparations of conjugates of a receptor-binding internalized ligand and a cytocide-encoding agent and compositions containing such preparations are provided. The conjugates contain a polypeptide that is reactive with an FGF receptor, such as bFGF, or another heparin-binding growth factor, cytokine, or growth factor coupled to a nucleic acid binding domain. One or more linkers may be used in the conjugation. The linker is selected to increase the specificity, toxicity, solubility, serum stability, or intracellular availability, and promote nucleic acid condensation of the targeted moiety. The conjugates are complexed with a cytocide-encoding agent, such as DNA encoding saporin. Conjugates of a receptor-binding internalized ligand to a nucleic acid molecule are also provided.

Patent CA-2228527-A1 (CA)
Title: Loose material combining and depositing apparatus
Inventor: SPERBER HENRY
IPC: E04F21/12
Filed: 1996-08-07
Abstract: An apparatus (10) combines two constituent loose materials to form a composite loose material and immediately deposits the composite loose material in a worksite area. The apparatus includes a single combining channel (34) for forming the composite loose material, and a separate hopper (12, 74) for each of the constituent loose materials which supply the constituent loose materials to the single combining channel (34). A single motor (16) is used for supplying both constituent loose materials to the combining channel (34).  One hopper (74) includes an auger (86) driven by the motor (16) through a drive train (24) and an easily accessible gear (102) for extracting the constituent loose material therefrom. The ratio of the constituent loose materials in the composite loose material is changed by replacing the gear (102) by rotating the one hopper (74) to disengage the gear (102) from the drive train (24), replacing the gear (102), and then rotating the one hopper (74) back until the replacement gear engages the drive train (24).

Patent CA-2229681-A1 (CA)
Title: Wire guard assembly for a string trimmer
Inventor: TREES GREGORY A
IPC: A01D34/90
Filed: 1998-02-16
Abstract: A string trimmer includes a wire guard assembly which retains a wire guard and debris shield on a motor housing. The wire guard is retained in a pair of grooves in the motor housing to capture the debris shield between the wire guard and an upper portion of the motor housing. The wire guard is locked in place by locking members on the bottom of the shield, thereby substantially permanently connecting the shield to the motor housing without the necessity of additional parts.
Patent CA-2233242-A1 (CA)
Inventor: HEITMANN WALTER
IPC: G02B6/38
Filed: 1998-03-27
Abstract: An physical-contact optical fiber connector for optical fibers has improved long-term stability. The fiber surface ends of the optical fibers are coated with a thin, absorption-free film made of very hard material, whereby the resistance to scoring is considerably increased. The thickness of the protective film is such that interfering reflection losses due to differences in the refraction indices are largely avoided. The hardness of the film is greater than that of the optical fiber material. Its optical thickness is also small compared to the operating wavelength. For optical fibers made of quartz glass, a protective film of Al2O3 is used. Other oxides, nitrides, borides, and carbides are also used. For optical fibers made of multicomponent glass or plastic, the protective film is made of an absorption-free material of greater hardness.  The optical thickness of the protective film is between 1/1000 and 1/10 of the operating wavelength. The films are applied using ion-supported processes or ion-beam sputtering or the MicroPlasma process. Due to the small diameter of the rods, a large number can be placed into the coating system and coated at the same time. Thus physical-contact optical fiber connectors are obtained that have virtually unlimited service life and have extremely small insertion losses or connection losses.

Abstract: La présente invention concerne un système radio cellulaire (1) pour terminaux à antennes (20) à faisceau étroit. Il donne une assignation de canaux en accès multiple avec assignation en fonction de la demande (AMAD), avec un critère de qualité garantie des canaux. L'invention possède un algorithme efficace d'assignation de canaux (46) qui utilise une base de données de caractéristiques d'interférences mesurées entre canaux pour les terminaux d'abonnés, pour éliminer les interférences importantes entre canaux, dans les canaux assignés. L'utilisation de caractéristiques mesurées d'interférences dans les terminaux élimine l'apparition d'importantes interférences aléatoires inattendues entre canaux, dans les assignations de canaux, permettant ainsi d'utiliser des systèmes plus efficaces, sur le plan du spectre, de réutilisation des fréquences cellulaires.

Patent CA-2239917-A1 (CA)
Title: Exercise machine
Inventor: BUSTARD JEFF
IPC: A63B21/02
Filed: 1998-07-14
Abstract: An exercise machine is comprised of one or more resistance units.      The unit(s) can be mounted to a ceiling, a floor, a wall, a freestanding floor unit, to opposing walls, an opposite floor and ceiling, opposing freestanding units; or the unit(s) can be mounted into frames which are so mounted. Necessary eyelets and pulleys attached to the frame(s) allow ropes to be presented to the user at various angles which are useful for resistance exercise. When the user pulls a handle attached to a rope a shaft is turned inside each resistance unit. A consistent amount of resistance is created because the resistance of the shaft to being rotated does not change over the duration of the exercise stroke. Changing the freedom of the shaft to rotate will vary the degree of this consistent resistance. Each rope drives a separate resistance unit, allowing for independent resistance settings and usage of each rope. The user can orient themselves to the exercise machine in any way, allowing for an almost unlimited number of exercise positions.

Title: An assay surface that permits an analyte releasing step
Inventor: EDWARDS STEVEN
IPC: G01N33/543
Filed: 1999-03-05
Abstract: Assays where harsh sample pretreatment for releasing an analyte is required are routinely performed in two separate vessels or on two physically separate surfaces. The present invention provides for the preparation of a surface suitable for performing assays where sample pretreatment is necessary. The appropriate surface is coated with a molecule coupled to biotin wherein the resulting surface is resistant to the analyte releasing step. It can then be overcoated with avidin. Treatment of samples with strong alkali and reducing agents to release complexed or bound analyte molecules prior to assay can be carried out in the presence of the coated surface without significantly reducing its binding activity. In this way, pretreatment and assay can be accomplished on the same surface or in the same reaction vessel.
