Patent CA-2091665-A1 (CA)
Title: Process for the synthesis of fullerenes
Inventor: TSANTRIZOS PETER G
IPC: C01B31/02
Filed: 1993-03-15
Abstract: A process is disclosed to synthesize fullerenes in a plasma reactor. It comprises introducing various amounts of carbon halides as the plasma forming gas in a plasma torch capable of producing a high enough temperature flame to dissociate the carbon bearing molecules into carbon and halogen atoms, hence forming a carbon cloud which condenses into a soot containing fullerenes. Also hydrocarbons and/or inert gases can be introduced in the torch as the plasma forming gas and reacted with carbon halides or halogens injected therewith or directly into the plasma flame at the exit of the torch. The process can use a high enthalpy non-transferred d.c. plasma torch or an induction plasma torch as the plasma generating device.

Title: Sequential power estimation for cellular system handoff
Inventor: KAY STANLEY E
IPC: H04W36/30
Filed: 1993-04-27
Abstract: Abstract SEQUENTIAL POWER ESTIMATION FOR CELLULAR SYSTEM HANDOFF            Cellular handoff is improved by tailing or adapting the measurement tine based on the characteristics of the received signal intensity or power.  More particularly, base stations typically measure mobile signal power in order to determine the necessity for handoff and the identity of a new cell.  The measurement time must be of a duration which is sufficient to characterize the environment of the mobile.  In accordance with the invention, the duration of the measurement time is determined from the received signal itself.  Once the duration of the measurement time is determined, that data may be passed to a target cell along with other handoff data.
Patent CA-2096647-A1 (CA)
Inventor: MOORE CHRISTOPHER P
IPC: F02B69/04
Filed: 1991-11-20
Abstract: A dual fuel injection arrangement for an internal combustion engine (1). Fuel is injected into the inlet manifold ducts to each engine cylinder via injectors (4, 5, 6, 7). An arrangement of valves allows selected supply of either a first fuel or a second fuel to the injectors (4, 5, 6, 7) via inlet fuel rail (8) and branch lines (9). Excess fuel is returned to each supply by way of return line (11). Electronic control units (31, 32) determine injection timing for the selected fuel dependent upon engine parameters for the first fuel and upon an adjusted timing for the second fuel where the adjustment takes account of the different characteristics of the second fuel compared with the first fuel. In particular there is disclosed an arrangement where the first fuel is gasoline and the second fuel is a liquified gas.

IPC: B01D17/02
Filed: 1990-11-30
Abstract: An apparatus to separate two immiscible liquids of different densities that form a two phase mixture comprising an upper layer (10) and a lower layer (12) when together. The apparatus has a main body (14) to receive the two liquids. The main body has a base and an open top. There is an outlet (20) adjacent the base of the main body, arranged tangentially. A pump (22) pumps liquid from the main body through the outlet (20). A jet (24) generally adjacent the centre of the main body (14) directs liquid upwardly from the body. The liquid is supplied to the jet (24) by pump (22).  Floats (30) allow floating of the apparatus in a mixture of the two liquids. The fluid driven from the outlet (22) draws the two liquids into the body and the liquid from the jet (24) forces the upper layer (10) of liquid upwardly to separate the two liquids.

Abstract: A cover forming apparatus for forming a flower pot or flower pot cover from a sheet of material by engaging a sheet of material about the outer surface of a mold, die or pot.      The cover forming apparatus includes a plurality of pivotable forming members resting in a surface which supports a sheet of material upon which is positioned a flower pot mold or flower pot. When the forming members are pivotally moved from the storage position to an extended position, the forming members cause the sheet of material to be appressed to or engaged with the mold or pot. The article formed in accordance with the present invention may be separable from the mold or pot and usable as a flower pot or flower pot cover or may be more or less securely attached to the pot by adhesive, cohesive, barbs, friction pinches or other securing means thereby forming a decorative cover connected to a flower pot. The forming members may be spaced by gaps in their closed positions, and gathering fingers can be employed in functional relationship to the forming members to produce different pot or cover features. The cover forming apparatus may be incorporated within a mobile platform enabling the cover forming apparatus to be moved from one location to another.
