Title: Method of Phase-Shifting Voltages Applied to Susceptances Interconnecting Two Synchronous Polyphase AC Networks and a Phase-Shifting Interconnecting Apparatus Thereof
Inventor: PELLETIER PIERRE
IPC: H02J3/44
Filed: 1994-05-09
Abstract: The method of phase-shifting a voltage applied to a susceptance interconnecting a phase line of a first polyphase AC network with a corresponding phase line of a second polyphase AC network, both AC networks being synchronous, comprises the steps of: connecting a primary winding of a transformer in series with the susceptance; deriving from the AC networks, an excitation voltage having a phase angle with respect to a phase voltage provided by the phase line of the first AC network; and applying the excitation voltage to a secondary winding of the transformer, whereby the excitation voltage combines through the transformer with the phase voltage to cause phase-shifting of the voltage applied to the susceptance.  This method is implemented with a phase-shifting interconnecting apparatus comprising series transformer arrangements having primary windings in series with capacitive and inductive susceptances, and secondary windings for receiving excitation voltages derived from the phase voltages of the first AC network.  Angles of phase-shifting produced by the series transformer arrangements can be changed either by changing portions of the primary windings connected in series with the susceptances, or by modulating amplitudes of the excitation voltages.

Title: Means for reducing the contamination of mass spectrometer leak detector ion sources
Inventor: BUTTRILL SIDNEY E JR
IPC: H01J49/10
Filed: 1995-11-20
Abstract: In a mass spectrometer leak detector an ion source assembly is disposed in a cavity of a vacuum envelope and is surrounded by a thin removable liner which has means for positioning this liner within the cavity. The liner positioning means limit the thermal contact of the liner with the vacuum envelope and due to heat-radiation relationship of the liner with the ion source the temperature of the ion source region increases and contamination of the ion source decreases.

Title: Trailer hitch assembly
Inventor: LAROQUE STAN
IPC: B60D1/40
Filed: 1996-01-31
Abstract: An adjustably extensible trailer hitch assembly is disclosed. The trailer hitch of the invention allows a driver trying to back up into the correct position to conveniently attach a trailer hitch more room for error. The trailer hitch provides a top plate assembly that attaches to standard holes provided in most factory bumpers. The top plate provides a vertically oriented pivot pin. A hitch receiver having a square steel tube body is pivotally mounted on they pivot pin. A hitch extension arm having an elongate pivot pin opening is also pivotally mounted, and is slidably carried by the hitch receiver. The extension arm carries an end plate on its rearward end, having a matrix of bolt holes which are adjustably attached to a ball mount plate also having a matrix of bolt holes. The ball mount bracket can therefore be attached to the extension arm at a variety of elevations. A U-lock pin, carried by the top assembly, may be lifted to an upper position which allows the hitch receiver to pivot, and is moved by gravity to a lower position preventing the hitch receiver from pivoting when the receiver is perpendicular to the bumper. A locking bolt prevents the hitch extension arm from extending, and also prevents the U-lock pin from moving to the upper position.

Patent CA-2173539-A1 (CA)
Inventor: NIKKANEN SAMULI
IPC: F23L13/02
Filed: 1996-04-04
Abstract: Combustion gas is fed to a furnace, preferably a recovery boiler for combusting black liquor from cellulose pulp processing, through a gas nozzle disposed in association with a wall of the furnace. The nozzle has a longitudinal axis of elongation, an exterior, and a hollow interior. Cooling gas is directed into contact with the nozzle exterior, and typically also the furnace wall where the nozzle engages the furnace wall. The cooling gas typically moves in a direction substantially perpendicular to the longitudinal axis of the nozzle, and cools the nozzle. Combustion gas passes through the nozzle hollow interior and enters the furnace facilitating combustion of black liquor within the furnace. Desirably the cooling gas is redirected and enters the nozzle interior as the combustion gas. The nozzle may be further cooled by cooling fins or studs on a portion of the nozzle exterior impacted by cooling gas. The rate of gas flow may be regulated to control the amount of gas redirected into the nozzle for use as combustion gas. The invention results in effective cooling of the nozzle to extend its life, recovery of heat from the nozzle by utilizing it to preheat the combustion air, and the prevention of clogging of the cooling air flow paths because they are maintained distinct from areas where furnace impurities exist.
