System for the processing of organic waste and products, which is equipped with, at least, one cylindrical cavity of treatment which is arranged with a loading area and a unloading area of waste and an entrance and exit of vapor. Inside the cylindrical cavity, a dragging spindle with direction of advance from the loading area to the unloading area is installed. The axis of the dragging spindle is equipped with mixing blades which conform a mixing spindle with a direction of advance opposite to that one of the dragging spindle.

A method of operating a temperature-controlled K-mixer for thermally and kinetically regenerating vulcanized crumb rubber is provided. The K-mixer includes a chamber and a shaft provided with a plurality of blades. The method includes the steps of inserting a mixture of vulcanized crumb rubber and a lubricant in the chamber of the K-mixer; heating the mixture by rotating the shaft of the K-mixer until the temperature of the mixture has reached a devulcanizing or regeneration temperature; cooling the mixture by reducing the rotational speed of the K-mixer and by circulating a cooling fluid in the shaft and in channels of the blades.

A segmented auger mechanism is mounted in the hopper of a concrete dispensing apparatus used to distribute a hydrated concrete mixture into a horizontally disposed form to manufacture pre-cast concrete structures, such as concrete wall panels used to form a foundation for a residential or commercial building. The auger mechanism is formed of connected segments that can be individually and independently removed from the concrete structure for service and repair. The auger is rotatably supported by a pair of end bearings supported on the opposing end walls of the hopper of the dispensing apparatus, and by at least one interior bearing rotatably supporting a jack shaft having opposing half-round connecting portions for attachment to a corresponding connecting portion on the auger shaft. Removal of a segment of the auger mechanism facilitates the removal of the entire auger mechanism to minimize the down time of the concrete dispensing apparatus.

Apparatus and methods for producing a foamed material. Pressurized gas is introduced into a multiple-component mixture that contains a catalyst-containing component and a crosslinker-containing component. The multiple-component mixture may be directly mixed and combined with the gas in a mixing device. Alternatively, the multiple-component mixture may be combined in a first mixing device and this mixture may be subsequently combined with the gas in a second mixing device. When dispensed onto an application target, the gas entrained in the multiple-component mixture expands to form the foamed material.

The invention relates to a method and to a device for homogenizing a glass melt in a melt receptacle, wherein at least one stirring device (10, 11) is disposed in the melt receptacle, which comprises a stirrer shaft (10) and a plurality of stirrer blades (11), and wherein a gap (16) is formed between a wall region of the melt receptacle (2) and the stirrer blades (11).According to the invention, the respective stirring device causes an axial feed action in an inner stirring region (12) between the stirrer shaft (10) and the stirrer blades (11) in order to feed the melt in the stirring region along the stirrer shaft (10). A melt flow brought about by the axial feed action seals the gap (16) against direct passage of the melt.According to the invention, a very high gap width can be achieved, thus preventing the abrasion of materials in the region of the marginal gap. This also reduces the complexity required for adjusting the device. According to the invention, a high level of homogenization can be achieved regardless of the entry point of the inhomogeneities.

A carpet cleaning machine for uniformly spreading a dry carpet cleaning powder onto a surface and working the dry carpet cleaning powder into the surface. The cleaning machine includes base having a hopper integrally formed therein, distribution slots on the bottom of the hopper, a rotary powder agitator inside the hopper, wheels for supporting the base over a floor surface and for rotating the powder agitator, a metering gate for controlling the dispensing of the dry carpet cleaning powder, a trigger located on the cleaner handle for controlling the metering gate, and a plurality of motor driven vertical axis rotary brushes for working the dry carpet cleaning powder into the carpet. The dry carpet cleaning powder is dispensed onto the carpet and allowed to sit for a short period of time to allow the dry carpet cleaning powder to absorb the dirt contained in the carpet. After the dry carpet cleaning powder has dried and absorbed dirt, the dry carpet cleaning powder and dirt are vacuumed from the carpet with an ordinary vacuum.
