Title: Circular rotary engine.
Inventor: GOODMAN WILLIAM A
IPC: F02B53/00
Filed: 1991-08-06
Abstract: A circular rotary engine comprises a housing having spaced concentric cylindrical walls (23, 26) defining an annulus therebetween with intake (28-I) and exhaust ports (27-E) through the sides of the walls and a cylindrical rotary piston ring (10) having multiple symmetrically undulating surfaces (c, d) on both ends and coaxial interior (20) and exterior (19) gears for shaft drive which rotates within the annulus while reciprocating between end ring members (9, 11) positioned within the annulus and secured at each end of the interior and exterior walls. The end rings (9, 11) have opposite facing undulating frontal surfaces (a, b) symmetrical with the undulating frontal surface (c, d) of the rotary piston (10) such that the piston ring surfaces cooperate with the end ring surfaces to alternately create a volume area and displace the volume area in some portion during rotation, thus alternately opening a series of chambers (5, 6, 8) on one end of the rotary piston (10) while displacing chambers (1, 2, 4) on the opposite end with the reciprocating movement during axial rotation of the rotary piston responding in motion against the symmetric frontal surfaces of the end rings. This motion is accomplished while maintaining frontal surface contact (12, 13, 14, 15) at all times, without restriction to rotation whereby frontal surface seal contact is maintained during axial reciprocation and rotary movement. All components are coaxial thus providing the rotary piston with controlled circular axial rotation within the annulus with the end ring members controlling reciprocation.

Abstract: The invention relates to a cladding resin composition curable by heat, ultraviolet radiation, an electron beam or the like. The composition comprises a polyoxyalkylene polyol phosphate ester (hydroxyl value: 10-2,000 mg KOH/g) and a polymerizable or reactive functional group-containing compound. This composition is highly conductive as it is and, without incorporation of the conventional conductive additives, can be used successfully in the field of coatings and protective films where electric conductivity is a requisite.

IPC: F02M69/46

Abstract: In the case of known fuel distributors, which have through valve openings for receiving fuel injection valves, there is a risk that, in the event of hot starting of an internal combustion engine equipped with this type of fuel distributor, vapour bubbles will form and these lead to starting difficulties of the internal combustion engine. 
<??>The new fuel distributor has a fuel supply line (29) divided by a partition wall (37) into a first duct (33) and a second duct (35), the second duct (35) serving as fuel reservoir, being connected to the first duct (33) by a through-opening (39) and connected to the individual valve receiver openings (5). After switching off the hot internal combustion engine, fuel free of vapour bubbles can collect in the fuel reservoir and, in the event of hot starting of the internal combustion engine, this fuel makes it possible for fuel which is free of vapour bubbles and easily ignitable to be sprayed through the fuel injection valves. 
<??>The fuel distributor according to the invention is especially suitable for fuel injection systems of mixture-compressing, applied- ignition internal combustion engines.

Abstract: A process for surface treating granules, as well as the granule product and surface treatment apparatus thereof. Granules, such as ammonium sulfate or potassium sulfate for use in commercial fertilizers, are surface coated with a solvent such as water, and then dried to remove excess solvent. In so doing, the particle surface is slightly softened and then recrystallized in order to enhance its strength. A gentle agitation means like a slowly rotating, cylindrical drum may be used to allow a predetermined amount of time for recrystallization of the granules, as well as to remove sharp corners of the product. The solvent may also include a small amount of solid additive such as starch in order to lend time-release and weather resistance properties to the product.

Abstract: La présente invention se rapporte au fonctionnement d'une retordeuse à friser de fausse torsion pour la fabrication de fils texturés. En particulier, elle indique un procédé pour le réglage de la force de tension du fil défilant derrière l'appareil de fausse torsion à friction. La force de tension du fil est réglée par le fait que la force de tension du fil mesurée en continu est transformée en un signal de réglage et que par ce signal sont commandées les composantes de force exercées sur le fil et déterminant la torsion et l'alimentation. A cet effet, la plage de réglage est choisie de telle manière que la modification du signal de réglage ne provoque pas d'influences perceptibles influant sur la qualité dans la zone de torsion et que la tension du fil soit située dans la plage souhaitée pour un rapport torsion/alimentation à choisir.
