Components of a pocket-sprung-mattress sub-assembly having individual metal springs retained within a matrix of fabric pockets are separated. A rotatable tearing drum 405 is driven by a drive motor 406. Tearing devices 407 are arranged to pull metal springs from a pocket-sprung-mattress sub-assembly during the rotation of the tearing drum 405. A feeding assembly 408 compressors an end portion of the mattress sub-assembly and moves this end portion continually to bring an end of the mattress sub-assembly into contact with the rotating tearing devices 407.

A foliage shredder that can shred inputted foliage matter into uniform sized particles without pulverizing the inputted foliage matter includes a housing, a shredding axle, a motor, a stand, a digital timer, a power cord, and a lid. The shredding axle is concentrically positioned within a cylindrical compartment of the housing and rotatably coupled to a rotor of the motor. A stator of the motor is externally connected to the housing and electrically connected to the power cord through the digital timer. The lid is terminally attached to the housing thus closing the cylindrical compartment. The cylindrical compartment functions as a container unit for the inputted foliage as the electrically powered shredding axle shreds the inputted foliage into uniform sized particles.

Disclosed is a pruning and sieving apparatus, which resolves time-consuming and laborious problems in the existing pruning method of flower plants. The pruning and sieving apparatus includes a hollow body, including two relatively disposed open axial ends; an interior pruning lining attached inside the hollow body, where the interior pruning lining includes a plurality of sidewall pruning holes arranged in a distributed manner; a sieving screen, where the sieving screen includes a plurality of sieving holes arranged in a distributed manner, and is disposed in the interior pruning lining to divide the internal space of the interior pruning lining into a pruning chamber and a collection chamber; and two end caps disposed on the two open axial ends.

A shredding device is provided comprising two shredding shafts arranged parallel to each other with shredding elements arranged thereon, wherein the shredding shafts are preferably rotatable mechanically synchronized to each other. A shaft-side coupling element is connected to a respective first end of the shredding shafts. The shredding device includes a housing with a housing-side coupling element is provided that can be coupled to the shaft-side coupling element. The shredding device includes a displacement device enabling displacement of the shredding shafts for decoupling and coupling the shaft-side coupling element from or to the housing-side coupling element.

Powder processing apparatus including a processing head functionally fixed to a driving unit via a fixation device. The processing head includes an inlet connecting unit configured to be connected to an input container containing the material to be processed and an outlet connecting unit configured to be connected to an output container destined to receive the processed material. The fixation device includes a pivoting element configured to rotate the processing head around a pivoting axis by a rotation angle between a first angular position where the material contained in the input container can be inputted in the processing head and where the processed material can be outputted in the output container, and a second angular position where the input container being on a base can be connected to the inlet connecting unit. Also disclosed is a method of using the powder processing apparatus.

An apparatus for decompressing/pulverizing and fluffing up bales of compressed thermal insulation includes grinding wheel and a grinding die adjacent thereto thereby forming a gap therebetween. The grinding wheel is constructed with a plurality of plane members cut from flat steel material and stacked longitudinally about a rotatable shaft. The plane members each include a perimeter surface which together form the grinding wheel mantle surface and protrusions thereon. Coupling rods extend through aligned holes in the stacked plane members and retain the plane members in their stacked positions. The grinding die is constructed with a plurality of die plates cut from flat steel material and which are stacked longitudinally. The die plates each include an abutment surface which together form the grinding die surface and protrusions thereon. Coupling rods similarly extend through aligned holes in the stacked die plates and retain the die plates in their stacked positions.

The bowl with attachable grinder for use with a pipe is a mechanical structure. The bowl with attachable grinder for use with a pipe claims the benefit of United States 35 USC 120 from non-provisional application U.S. Ser. No. 16/253,282 filed on Jan. 22, 2019. The prior disclosure comprises a partitioned bowl. A gas phase of a pharmacologically active media generated by the combustion of a smoking material passes through the partitioned bowl. The bowl with attachable grinder for use with a pipe comprises an exterior screw thread and a burr grinder. The exterior screw thread removably attaches the burr grinder to the prism structure of the partitioned bowl. The burr grinder grinds the smoking material in preparation for the combustion of the smoking material within the partitioned bowl. The burr grinder deposits the ground smoking material directly into the prism structure of the partitioned bowl.

A method of producing a powder suitable for additive manufacturing and/or powder metallurgy applications from a precursor particulate material comprising: subjecting the precursor particulate material to at least one high shear milling process, thereby producing a powder product having a reduced average particle size and a selected particle morphology.

An apparatus for bagging leaves is disclosed as including a gathering bin comprising an inlet having a larger mouth that tapers to an outlet having a smaller mouth. The apparatus further includes a tunnel that has a first end coupled to the outlet, and a second end that includes an attachment mechanism configured to releasably secure a garbage bag. In certain embodiments, the gathering bin has a floor configured to contact the ground, and a canopy above the floor. In certain embodiments, the canopy is supported by flexible and removable rods, thereby allowing the apparatus to be collapsed and stored when not in use. A corresponding method is also disclosed.
