Title: Improved acidification of tall oil soap using carbon dioxide
Inventor: HUIBERS DERK T A
IPC: C09F1/00
Filed: 1993-05-19
Abstract: The present invention relates to the conversion of tall oil soap to produce crude tall oil. An aqueous tall oil soap solution generated in a kraft wood-pulping process is placed in contact with carbon dioxide under pressure (22), to form crude tall oil and sodium bicarbonate brine. The crude tall oil and sodium bicarbonate brine are then allowed to separate, under pressure (24), into a crude tall oil layer (28) and a sodium bicarbonate brine layer (26). The crude tall oil layer is then separated from the sodium bicarbonate brine layer, again under pressure. The separated crude tall oil may then be further refined to yield fatty acids, resin acids, and other constituents, which are useful in numerous industrial applications, such as in soaps, lubricants, inks, adhesives, and coatings.

Title: Surface Treatment for Silicon Substrates
Inventor: CUNNINGHAM JOHN EDWARD
IPC: H01L21/203
Filed: 1995-04-20
Abstract: A method for desorbing the surface oxide on a silicon substrate is performed by implanting particles such at atomic or ionic hydrogen into the oxide layer on the silicon substrate. The oxide is then removed by breaking the bonds between the silicon and oxygen atoms within the oxide. The bonds may be broken by heating the substrate, for example. The temperature to which the substrate must be raised is substantially less than the temperature required to desorb an oxide layer that has not undergone an implantation step. In one particular example, the particles implanted into the oxide surface are hydrogen ions generated by electron cyclotron resonance.

Patent CA-2151653-A1 (CA)
Inventor: PEEVER H JAMES
IPC: B63B21/54
Filed: 1995-06-13
Abstract: It is common practice for pleasure boaters to moor their craft to fixed and buoyed moorings by securing a line from the vessel to a ring attachment on the mooring.   To accomplish this normally requires one person standing at the bow to capture the ring on the mooring with a boat hook and lift the mooring ring sufficiently so that a line can be passed through the ring and secured to the boat.          This procedure has to be performed from a height of one to three meters above the water and sometimes can be hazardous.    With the present invention,  the mooring procedure can be performed with increased safety and with a  single  action by utilizing a hook mechanism comprising a rigid body and a spring loaded detachable arm attached to a common extension pole and used to pass a line through a continuous ring and recovering said line.          The  rigid body has  guided  cavities  incorporated  at  specific locations within the rigid body to receive the detachable arm.  The hinged spring loaded detachable arm assembles to the body forming the approximate shape of a closed hook.  The arm is temporarily maintained to the body by pressure exerted by a spring at the hinge of the detachable arm.   The arm hinged at one end allows the opposite end to lift permitting passage of the ring between the body and the arm.  Spring loading of the arm equalizes any forces created when passing the mechanism over the ring.  The arm also serves as a retainer for the line being passed through the ring.          The  combination  of  the  rigid body and hinged  spring  loaded detachable arm with line attached facilitates passage of the line through a fixed continuous ring and recovery of the line thus forming a line loop around the ring all in one single swift action.
Patent CA-2153470-A1 (CA)
Inventor: GUEST JOHN ROBERT
IPC: A01K85/02
Filed: 1995-07-07
Abstract: A fishhook device comprises a hook unit and a lure member releasably fastened together. The hook unit comprises a first arm having a first hook at one end and a releasable fastener part at its opposite end, and a second arm with second and third hooks at one end and its other end portion joined to the first arm. The hooks each comprise a point and a curved portion. The curved portions of the second and third hooks diverge, one to each side of a longitudinal axis of the unit, and curve towards the second arm. The first hook curves towards the second arm in a plane through the longitudinal axis. The lure member has a second releasable fastener part and a loop spaced apart along the longitudinal axis. The second arm is releasably fastened to the lure member by cooperation of the first and second releasable fastener parts and by extension of the second arm through the loop. The second arm is movable from a first position, in which the two arms are apart and the points of the hooks are shielded from entanglement with weeds, to a second position, in which the arms are together and the points of the hooks project clear of the lure to snag a fish having its jaws clamped around the unit. The lure member may be a plate or "spoon". Alternatively, the lure member may be a bait replica of plastics material, perhaps shaped as a frog, and attached to the hook unit by means of a plate member provided with an appropriate second releasable fastener part. In the latter case, the plate may have a tang which is inserted into the body of the replica. In the first position, the point of the first hook is shielded by the second and third hooks and the points of the second and third hooks are shielded by the body of the bait replica. In the second or actuated position, the hooks protrude clear of the body. In the case of a frog-shaped lure member, the hooks conveniently protrude between the legs of the frog.

Title: High efficiency gas furnace
Inventor: DANESHVAR MANOUCHEHR
IPC: F23D14/16
Filed: 1995-08-01
Abstract: A high efficiency gas furnace utilizes a unique pre-mix design in combination with a pressurized/high velocity combustion process. The combustion process occurs in a combustion chamber and the high temperature high velocity products of combustion follow a circuitous route from the combustion chamber through finned tubular conduits to an exhaust. Heat from the high temperature high velocity products is transferred to the finned tubular conduits. An air blower assembly forces air across the finned tubular conduits and the combustion chamber to remove the heat from the finned tubular conduits and transfers this heat to a building or an enclosed portion thereof.
Patent CA-2155218-A1 (CA)
Title: Multi-phase electric machine with offset multi-polar electric pole units
Inventor: HILL WOLFGANG
IPC: H02K41/02
Filed: 1994-01-31
Abstract: Known multi-phase electric machines have conductor lanes which do not sufficiently utilize the space available in the grooves and winding overhang or which are costly to produce. Besides a good utilization of the available space, the length of the conductors in the winding overhangs should be kept short in order to obtain high effiency and power densities, and the number of different conductor designs should be minimized in order to reduce production costs. According to the invention, the electric machine consists of several electric pole units which have each a small number of phases and poles with alternating polarity in the direction of displacement. The electric pole units are located next to each other in the air gap and are mutually offset by a fraction of a pole pitch with respect to the rotor poles. Their meandering rectangular conductor wires extend in layers parallel to the air gap. In monophase electric pole units, the conductor insulation is designed for only a fraction of the terminal voltage; by small increments a high effective conductor proportion is achieved. The modular design allows electric machines to be assembled from a few different structural shapes which, because of their simple design, may be produced on a large scale in a totally automated manner.
