Abstract: An ice block press device (10). The press (10) includes a compression chamber (12) into which raw ice particles (20) are fed through an opening (82). A ram (16) is employed to urge ice particles (20) deposited through an input chute (18), through the opening (82) into the compression chamber (12). The ram (16) cyclically reciprocates to push the particles (20) into the chamber (12).

When this occurs, the ram (16) is precluded from achieving its fully extended position. Upon sensing this condition, a knife (80) is driven to cut the block to a uniform length.

Abstract: An apparatus for handling round bales of hay, straw or the like material. In general terms, the handling comprises dispensing a round bale of hay or the like material by unwinding the bale and feeding the thus produced continuous mat into the inlet device of a compactor, typically employing the compacting mechanism of a known square baler. The compactor compacts the material fed into it to produce a second, compacted state generally similar to square bales. Thus, in brief, the invention converts the round bales into the square bales. In a particularly preferred application of the invention, the continuous compact mass of the material is fed directly into a grinder-mixer. The grinder-mixer, being usually on a mobile frame, can thus be fed from a round bale.

Abstract: A method and apparatus for compressing fibrous material into dense bales having uniform size, shape and weight. Weighed longitudinally extended charges of material having a predetermined transverse dimensional profile are individually loaded into a compression chamber defined by side plates and first and second movable end platens. A long-stroke small-diameter hydraulic piston pushes the first end platen against the charge toward the second end platen, partially compressing the charge. The first end platen is then latched in a fixed position at full stroke while the second end platen, via a short-stroke large-diameter hydraulic piston, applies a further compressive force to the charge against the first end platen. The resulting fully compressed charge is pushed out of the compression chamber, bound loosely while still fully compressed, then released, whereupon the bale longitudinally expands into the bindings to a predetermined length.

The paper roll is compressed by moving the compressing plate member toward the spanning wall member and is deformed into a flat shape until a diameter of the paper roll is reduced to a thickness within the range between one-half and one-fifth. A degree of the compression is regulated so that the volume reduction can be effectively obtained while it can be easily restituted to its original shape.

Abstract: An extrusion-type trash compactor in which the trash receiving chamber is inclined downwardly towards an outlet opening at an angle of about forty-five degrees, and the outlet opening connects with the inlet of a compacting chamber that is disposed horizontally, whereby the overall length of the compactor is reduced to adapt the compactor for use in smaller trash rooms. The angle of the ram also functions to reduce blockages in the hopper by working the bottom of the accumulated pile of trash as it's moved relative thereto - which reduces the possibility of trash backing up into the chute leading into the hopper and thus reduces damage that may be caused by fire. The compacting chamber is also pivoted to the outlet opening of the receiving chamber to permit it to be opened for the purpose of clearing jams in the compacting chamber.

Abstract: A first body has a cylindrical section that is adjacent a conical section so as to form a constricted passage through which granular solids are forced under pressure. Passage through the constriction results in the application of shear forces to the granular solids which degrades some of the particles to create fines to fit between the larger particles and which induces interparticle motion that facilitates the compaction process. After passing through the constriction, the compacted solids are received in a cylindrical receiving chamber, into which a piston can be inserted for the application of direct compression forces. In a preferred embodiment, the granular solids are forced through several constricted passages in sucession, resulting in several stages of compaction prior to the final stage of direct compression.

Abstract: A knitted, woven or non woven article such as a glove for example, having a wrist cuff includes an edge binding which is activatable by the application of heat thereto to prevent unraveling of the cuff edge. The bound edge is defined by first and second yarn ends which are knitted or woven together, wherein the first yarn includes a heat activatable, thermoplastic outer covering and the second yarn is defined by a nonthermoplastic, elastic material. The first and second yarns are knitted or woven in a manner to form crossover points therebetween. The edge binding is subjected to heat in order to melt the thermoplastic outer covering of the first yarn, thereby joining the first and second yarns at the crossover points. The articles may be formed on conventional, automatic knitting machines. The knitted articles are ejected from the machine and are gravity fed into a device which melts the thermoplastic outer covering of the first yarn, and thereby bind the edge of the article.

Abstract: A stationary chamber is located below an apron on which garbage and other refuse is dumped from collection trucks. An opening in the apron is aligned with an opening in the top of the chamber. The discharge end of the chamber is closed by a gate which slants rearward at an angle of 15.degree. to the vertical against which the refuse is compacted. The gate may be raised when the chamber is to be discharged. Reciprocating within the chamber is a platen having its upper portion slanted forward at about an angle of 42.degree.. The platen is driven by a multi-stage hydraulic ram. Loads of about 15 cu. yds. are dumped into the chamber opening by a bulldozer. The bulldozer operator by a radio control causes the platen to move forward, compacting the first load to about one-half the original volume of the loose material. When the ram pressure reaches a predetermined pressure, the platen is automatically retracted. The operation is repeated until a predetermined weight has been received and compacted.
