The details necessary for embodying the present invention are: a supporting frame; two rotors; a system for the periodic alternating motion thereof with phases of 0.degree. and 90.degree.; two tubular 2-phase circuits (CB) consisting of two parallel identical tubes termed "active circuits" with an inlet and outlet tube at the connection points; starting from the inlet, where to each circuit is applied a one-way valve with the task of allowing only inlet of the liquid, the two circuits constituti...

Chocolate is ground in order to obtain a very small average particle size. A determined viscosity is necessary for further processing. In order to keep as small as possible the fraction with particle size lying above the desired value and having an adverse effect on the taste of the final product, according to the invention the process mass is circulated in a cycle incorporating a grinding device and a ball mill. This has the result of accelerating the grinding process and reducing the inconsist...

The method of coating composite material parts with a refractory and/or metallic product includes the successive steps which consist of applying to the walls of the polymerization mold a layer of a binder which is volatile or decomposable during the polymerization heating, projecting onto said walls at least one layer of said coating products, positioning the fiber and resin fabric layers inside the mold, carrying out polymerization under pressure by heating, and then removing from the mold.

A gas/liquid interface structure for transport of a gas stream from an upstream source of same to a downstream processing unit, comprising first and second flow passage members defining an annular volume therebetween, with the second flow passage member extending downwardly to a lower elevation than the lower end of the first flow passage member, with an outer wall member enclosingly circumscribing the second flow passage member and defining therewith an enclosed interior annular volume, and wit...

Method and apparatus for synchronizing access to a memory shared among a plurality of processors is described. In one example, each of the plurality of processors includes a primary bus for communicating with the memory and a secondary bus. A synchronization block is coupled to the secondary bus of each of the plurality of processors. The synchronization block includes at least one semaphore for controlling access among the plurality of processors to at least one data segment stored within the m...

In a sheet feeding mechanism wherein a spring can be used to properly regulate a sheet feeding position, sheets are not deformed in spite of the urging force of the spring, and a required conveying force is prevented from being increased after sheet feeding. Specifically, immediately before a sheet is fed, a driving mechanism is used to move a slide plate leftward. A driving portion of the slide plate pushes an arm of a lever to rotate the lever counterclockwise against a tension spring. Thus, a...

A roller coaster with a figure-8-shaped track section has a hoisting section on one side of a loop enveloping the figure 8, followed by a descending section extending over the entire opposite side of that loop from the highest to the lowest track level passing around the end of the loop at a tilt angle 80.degree., thereupon continuing upwardly beneath the hoisting section to the other end of the loop; there follow two intersecting, undulating S-curves, defining the figure-8 portion of the track,...

A pulverizing mill is provided with a spider frame which is mounted on the main pulverizing rollers. Flexibly secured to the spider frame are spacer means which are positioned between the rollers.

The rotary engine piston and seal assembly is disclosed that improves engine efficiency and power and reduces wear on an inner housing surface. It has a somewhat cube-shaped piston and a pair of grooves running around all four sliding side surfaces. The grooves contain a series of segmented metal seals and are compressed against the mating surfaces by a group of seal springs.
