Abstract: The present invention is a biomass compactor. The device is made up of a frame having a hydraulic compaction cylinder. When the hydraulic control is activated, the compaction cylinder moves forward through a hopper filled with various biomass materials, such as but not limited to, yard waste and food waste products. The compaction cylinder pushes the raw biomass material into the compaction area, thereby compressing the biomass material. When the compaction cylinder is retracted, the hopper can then be refilled and the compaction process repeated as desired up until the point where the compression area is full. The resulting compressed biomass material is removed and can be used as fuel, such as by burning the resulting compressed biomass material in a fireplace or wood burning stove.

Abstract: A feedback control system for use in a press machine is adapted to monitor and adjust the clearance between the gib and slide. A pressurized chamber, such as a hydraulic piston-cylinder combination is disposed in actuating relationship to the gib. Selective pressurization of the piston-cylinder induces a controlled displacement of the gib towards or away from the slide, thereby regulating the spatial relationship therebetween. A sensor provides a measure of any possible clearance between the gib and slide. The clearance measurement is compared to allowable reference data. A controller controls the pressurization of the chamber in accordance with the comparison results, thereby controllably moving the gib. The gib may be selectively displaced to optionally effectuate a minimal clearance condition.

Abstract: The present invention provides a slide guide for a press which comprises a gib structure with a spherical surface. The gibs are formed on a frame of the press. The spherical surface is provided with a holder or a cap to cover the spherical surface. The surface contacts are formed between the spherical surface bodies and the gibs or between the caps and the gibs. Forming spherical contact surfaces prevents damage to the sliding surface. This slide guide provides uniform, secure contact at a sliding surface of a press and prevents uneven contact. The spherical surface body can be easily installed and can adapt to deformation of the slide and prevent damage to the sliding surface.

Abstract: A pair of upright arms are connected at their lower ends to an anchoring beam that lies on the floor after the truck is driven onto a ramp. The front truck axle is positioned below the top ends of the upright arms, which are then joined by a pressure distributor located above the axle to form an upright arm assembly. A hydraulic ram presses upwardly against the axle, which is restrained by the pressure distributors, thereby bending the axle to align the wheels. A system of countersunk apertures and mating conical frustrum fittings and bushings distribute the resulting forces more evenly throughout the apparatus, thereby preventing bending of the upright arms.
