Patent CA-2158510-A1 (CA)
Title: Self-powered extensible device
Inventor: FRAZIER RICHARD K
IPC: F41B15/02
Filed: 1995-09-18
Abstract: A baton-like device is provided with a hollow telescopic ram or bolt member which can be driven to extend out of a barrel or trunk portion of the baton. The driving force is produced by a source of gas under pressure, which in preferred embodiments, takes the form of explosive cartridges and which can be repeatedly and automatically operated in a manner similar to an auto-matic shot gun.  The force with which the ram is driven can be modulated using a pressure by-pass or by selection of the cartridges, or both.  In order to reduce the risk of a fatal impact, the tip of the ram is provided with a blunt knob which can further include an inflatable cushion like member which is supplied with air or gas as the ram is displaced out of the barrel.  The knob is removable allowing projectiles such as tranquilizer darts to be launched by loading the projectile into the hollow bolt and catapulting them towards a target or targets. Alternatively, the knob can be replaced with a chisel-like cutting tool and used as an emergency cutter in the event of a vehicle accident.

Inventor: CUNNINGHAM JOHN
IPC: F16L3/02
Filed: 1994-03-23
Abstract: A method of supporting distribution means (42), such as a pipeline, that accommodates temperature-induced expansion or contraction of the distribution means as well as unexpected, infrequent shocks to the structure, and provides effective thermal isolation of the distribution means from the surface on which the structure rests. The method includes arranging laterally spaced apart fixed bearing supports (44) on a surface adjacent a path or distribution means and supporting elongated elastic members (50) on the bearing supports at a distance spaced inwardly from the ends of the elastic members. Distribution means (42) may be placed in association with the elastic members (50). Beginning from an equilibrium state, each elastic member (50) is capable of bending in the proportion to the magnitude of an additional load applied intermediate the ends of the elastic member, with the ends of each member sliding against the bearing members a distance also proportional to the magnitude of the additional load.

Patent CA-2160882-A1 (CA)
Inventor: MERENDA JOSEPH T
IPC: H01Q21/00
Filed: 1995-02-28
Abstract: Dans des systèmes de communication cellulaire, on peut utiliser des antennes réseau fentes simplifiées de haute fiabilité. En forme de panneau plat, l'antenne selon l'invention comprend un réseau à fentes avec une source primaire simplifiée confinée dans une structure à panneau arrière et d'un radôme avant. L'utilisation d'une source primaire simplifiée comprenant, d'une part, un pilône vertical en aluminium avec un espacement diélectrique par rapport à la plaque d'aluminium et, d'autre part, un réseau vertical d'ouvertures à fentes en alignement horizontal, est rendue possible grâce à la disposition horizontale excentrée des fentes. Avec un pylône à source primaire linéaire, le couplage des signaux avec chaque fente en série est déterminé par l'emplacement horizontal de chaque fente par rapport audit pylône à source primaire. Avec la liaison d'entrée capacitive, il n'y a pas de contacts ou de connexions électriques sur le trajet interne de la source primaire qui puissent provoquer des effets d'intermodulation. Grâce à la mise à terre de la plaque réseau en aluminium, à la conception en forme de cage et au fait que la source primaire soit à liaison capacitive, l'antenne résiste à la foudre. Les modèles d'antenne avec des inclinaisons de faisceaux différentes n'exigent qu'une substitution de plaque réseau en aluminium, avec des configurations de fentes différentes. Des largeurs de bande en azimuth plus étroites sont assurées par l'utilisation de multiples réseaux à fentes, et l'on peut adapter de multiples antennes directives aux fins de l'utilisation de réseaux conformateurs de faisceaux et de techniques d'orientation active du faisceau d'antenne et de recherche du zéro.

Title: Self-aligning photoplethysmograph sensor
Inventor: HARTWIG ROBERT WILLIAM
IPC: A61B5/024
Filed: 1996-02-02
Abstract: A self-aligning photoplethysmograph sensor includes a flexible, resilient web loop having a circumference smaller than the circumference of a body part onwhich the photoplethysmograph sensor is to be used. The loop is formed by an inner loop of a resilient material covered by an outer loop of fabric. A red light emitting diode, an infrared light emitting diode, and a light detector are mounted on the inner surface of the inner loop with the light detector directly opposite the light emitting diodes. As a result, when the loop is placed around a finger, light emanating from the light emitting diodes shines through the finger and is incident on the light detector. A pair of conductive leads bonded to the inner surface of the inner loop extends in a serpentine manner from each of the light emitting diodes and the light detector to a cable junction on the outer loop. A cable has a respective plurality of wires that are connected at one end to the conductive leads and at the other end to respective pins of a cable connector that is mounted on the other end of the cable.
Patent CA-2171042-A1 (CA)
Title: Circuit for demodulating fsk signals
Inventor: KENNEDY JOHN F
IPC: B60R25/04
Filed: 1996-03-05
Abstract: A circuit and method of demodulating an FSK signal uses digital circuitry to convert the received signal into count values.  For each reception an adaptive reference count value is determined by averaging the duration of received pulses during the preamble of the transmission.  The adaptive reference count corresponds to a demodulated logic "1" or logic level "0".  The counts from the coded portion of the transmission are compared to the adaptive reference count.  If the count is within predetermined windows from the reference count, the count value is converted to the corresponding digital signal.

Title: Hydraulic cement with accelerated high strength development
Inventor: ULIBARRI RAMON POO
IPC: C04B7/32
Filed: 1996-12-18
Abstract: The invention consists in a method of manufacturing cements based on calcium sulfoaluminate, consisting in the format ion of a klinker through the roasting of raw materials to temperatures of more than 1200°C in such a manner that the klinker thus produced has a high content of calcium sulfoaluminate, tricalcium silicate and dicalcium silicate and, during the milling thereof or prior to the milling thereof adding to the klinker thus produced with the above recited basic components, optimal amounts of calcium oxide or hydroxide and calcium sulfate, in order to activate said klinker. Upon said milling, a temperature of about 100 to 125°C is to be observed and a time enough to convert gypsum to hemihydrate, thus making that the calcium sulfate present in the thus obtained product be in a condition to react quickly during tyre hydration of said cement; thus giving place to the formation of etringite; for which the presence of a pH above 12 is needed. Of course, it is also claimed as a novelty the activated cement, resulting from the calcination and milling methods of this invention.
Patent CA-2199834-A1 (CA)
Inventor: BIELAGUS JOSEPH B
IPC: D21B1/02
Filed: 1995-04-25
Abstract: A chamber (22) has an outlet (24) which opens downwardly to the atmosphere and an upwardly opening air return plenum (28). A duct (38) is inclined upwardly at approximately sixty degrees to the horizontal, and a fan (32) mounted therein directs moving air (36) into the chamber (22). An upwardly inclined ramp (40) is positioned within the duct (38), and communicates between the chamber (22) and a downwardly opening discharge opening (46) in the duct (38).  A metered supply of wood chips (52) is fed down a sixty degree incline (56) onto the ramp (40) through the air stream (36) which is moving through the duct (38). Lightweight chips (55) become entrained in the air (36) and are separated from the rocks, tramp metal and knots (50) which slide down the inclined surface (40) and exit through the opening (46) in the duct (38). The entrained wood chips (55), together with the air (36) from the fan (32), are directed into a baffle (58) spaced within the chamber (22). By forcing the air (36) and chips (55) to move in a curved path, the baffle (58) separates the chips (55) from the air stream (36). As the air stream (36) expands into the chamber (22), its velocity drops then passes through the chip stream (52) up to the air return plenum (28). The chips (55), under the force of gravity, continue their downward flight, and exit the chamber (22) through the outlet (24). An inclined ramp (40) with a slowly moving conveyor (168) may be used to avoid a build-up of material (50) on the inclined ramp (40).
