Title: Semisolid product dispensing head
Inventor: RUSCHKE RICK R
IPC: D04H3/14
Filed: 2000-06-29
Granted: 2006-05-09
Abstract: A method of making a head for a semisolid product dispenser, such as a gel deodorant dispenser, comprises the steps of: providing a piece of porous media having a desired shape with a perimeter and openings through the media in the area inside of the perimeter, compressing at least the portion of the media inside of the perimeter between two parts of a hard tool so as to crush the media, thereby reducing the size of the openings, and affixing the porous media to a head frame to form the semisolid product dispenser head. Preferably the porous media is affixed to the head frame by an insert injection molding process, and the media is crushed in the same mold tool as is used to mold the head frame. A preferred porous media is made of two layers of extruded strands of polymer, where the strands in one layer are generally parallel to one another but are non-parallel to the strands in the adjoining layer, the strands are bonded at crossover points between the layers and have openings defined by spaces between the strands in one layer superimposed over spaces between strands in the adjoining layer. Preferably the head of the semisolid product dispenser is made by ultrasonically weldin g the head frame to the body using a combination of double shear and energy-directing ultrasonic weld joints, coupled witha positive stop.</SDOAB >

Patent CA-2317657-C (CA)
Inventor: SHAW JAMES G
IPC: F04D1/12
Filed: 1999-01-21
Granted: 2004-10-26
Abstract: An insert (40) is provided for attachment to the inlet or nose of a pilot tube (10) to withstand the wear and damage imposed on the inlet of the pilot tube by high velocity and high pressure fluid moving through the rotary casing and into the pilot tube.  The insert (40) reduces the amount of damage normally done to the pilot tube (10) under normal operating conditions thereby extending the life of the pilot tube. When worn or damaged, only the insert needs to be replaced rather than the entire pilot tube as is done in conventional systems. The insert (40) permits the machining of the insert to meet the specifications of a particular application, thereby providing the ability to control pump performance over a wider range of operational conditions.

Abstract: A first coupling member has a peripheral facing surface with a pair of annul ar raised locking tabs (76, 78), each of a different length and width. A second coupli ng member has a lock ring (40) longitudinally slidable thereon with a facing surface having a pair of annular slots (64, 66) sized to correspond to the respective annular tabs. A resilient annular spring (42) mounted within the lock ring urges it toward the first coupling member so th at the locking tabs engage their respective slots when the coupling is tightened to a predetermined extent during rotation in the locking direction to releasably and positively lock the coupling. An indicator strip (74) on the peripheral edge of the first coupling member is exposed before t he locking tabs and slots are engaged. Alignment between the respective locking tabs and slots allows longitudinal movement of the lock ring so that it covers the indicator stripe. One of the  coupling members has a peripheral groove and two angularly spaced longitudinal keyways of differing widths which intersect the peripheral groove. The annular spring has an internal peripheral edge with a plurality of peripherally spaced spring tabs for holding it in the peripheral groove. A spring key on the internal peripheral edge of the annular spring has a width correspondingto the width of one of the keyways to rotationally position the annular spring with the coupling member. The annular wall of the lock ring has two angularly spaced keys of differing widths which correspond to the widths of the keyways and are received therein to angularly position the lock ring with the coupling member and the spring.

Title: Crank system with sinusoidal piston motion
Inventor: BARSKI WOJCIECH GRZEGORZ
IPC: F02B3/06
Filed: 2000-12-18
Granted: 2003-05-06
Abstract: A crankshaft system for internal combustion engines built for record rotational or racing speeds and power because of a pure sinus piston motion, low friction and small size. The system is based on hypocycloid movement, but with small diameter of (eccentric) circular cam driving one- or double-sided piston. The circular cam performs flat motion: uniform rotation in its own plane plus a straight-line sinusoidal reciprocal movement. It substitutes a connecting rad and drives the piston directly. A piston skirt and wrist pin are absent, the piston itself may be double-sided (boxer), in one piece, and light. Self compensating mechanism maintains high precision of sinus piston motion over the life of the system, compensating for wear and thermal dilation. Full balancing even of one-cylinder engine may be achieved. An engine 90° V2 is inherently fully balanced. Intrinsic lack of forces acting on cylinder walls means high mechanical efficiency -cylinders are subjected only to the piston's rings friction. This makes the system easy to cool, or allows for more power. Very suitable for all supercharged engines and Direct Injection Diesel. Suitable for one-cylinder engines, V2 (especially 90°), V, boxer, X, star or in -line.

Abstract: Lors de l'extrusion de matières premières alimentaires en granulés et de produits de consommation connexes, les produits extrudés sont sujets à une expansion du fait de l'entrée en ébullition de l'eau qu'ils contiennent lorsque, après avoir été soumis à une forte pression d'extrusion ainsi qu'à des températures élevées correspondantes, ils sont expulsés dans l'atmosphère par les buses d'extrusion. Cette expansion est voulue, mais il est souhaitable d'être en mesure de la maîtriser, ce qui est difficile par la seule adaptation des paramètres du procédé classique. Il est possible, grâce à cette invention, d'agir sur cette expansion de façon constante, notamment en procédant à l'extrusion dans une enceinte close dans laquelle règne une surpression de quelques bars par rapport à la pression atmosphérique, surpression sur laquelle on peut agir. Les produits d'extrusion sortent de cette enceinte sans discontinuer ou de façon intermittente par lots. L'existence d'une surpression permet de modérer la formation de vapeur dans le produit extrudé auquel il est laissé un certain délai pour qu'il se stabilise avant de se trouver soumis à la pression atmosphérique, de sorte que la formation subséquente de vapeur ne modifie que faiblement sa structure.

Granted: 2004-12-28
Abstract: A wet flue gas desulfurization process for removing sulfur dioxide from flue gases. The process utilizes an ammonium sulfate scrubbing solution (22) to produce ammonium sulfate as a valuable byproduct. The scrubbing solution (22) contacts the flue gases and absorbs sulfur dioxide within an absorber (12) of a flue gas scrubbing apparatus (10), and is then accumulated in a tank (18) where the absorbed sulfur dioxide is reacted with oxygen and ammonia to produce ammonium sulfate. The scrubbing solution (22) has a concentration of greater than 46 % ammonium sulfate so as to have suspended solids of ammonium sulfate precipitate, preferably 1 % to 20 % suspended solids.
