摘要： A radial piston pump has a rotor provided within a cylinder chamber in such a manner that a center axis of the rotor is offset from a center axis of the cylinder chamber. The rotor has three working chambers a piston is slidably provided each of which. Each working chamber may connect with a suction groove or a discharge groove so that there exists a couple of situations, one of which is that two working chambers connect with the discharge chamber simultaneously and another one of which is that single working chamber connects with the discharge chamber. In order to make the forcing point at which total biassing force of the piston is focussed move gradually, the radial piston pump has a delay angle at a front side of the suction chamber. Namely a pressure within the working chamber is preliminary reduced before the working chamber connects to the suction groove so that the forcing point should shift gradually.

摘要： The invention relates to a blow molding machine for the blow molding of hollow articles, with an accumulator head (1) for producing a preform and with a blow mold for forming a hollow article from the preform. After completion of a blow molding sequence, a piston positioning signal is derived by a control system (15), to regulate the position of a discharge piston (4) in the accumulator head (1), from a comparative signal of the actual position and set position of the discharge piston (4). The set position is determined by integration from a previously specified speed set point profile. The control system (15) further superimposes an influx signal on the comparative signal, which corresponds to the change in volume of plastic flowing from an extruder (2) to replace the discharged contents of the accumulator head (1). The deviation between an actual cushion and a set point cushion for the plastic remaining in the accumulator head at the end of the discharge step is reduced by regulating the rotational speed of the extruder.

摘要： A disclosure relates to an apparatus for extruding and forming blanks from a rubber or polymeric material comprising a pair of hydraulic ram operated extruders having outlets connected to a common delivery conduit. A screw extruder is also connected to the conduit and a control valve controls flow between the respective extruders and conduit such that in one position of the valve one of the ram operated extruders is connected to the conduit outlet delivery of extrudate and the other extruder is connected to the screw extruder to receive a fresh charge of extrudate. A closed hydraulic circuit links the hydraulic rams of the two ram extruders whereby filling of one of the extruders causes that ram to retract and pump the hydraulic fluid therefrom to the other extruder to cause that ram to extend and thereby discharge the extrudate therein and vice versa. By feeding extrudate from the screw extruder, the hydraulic ram extruder being charged is caused to receive extrudate and the ram extruder discharging extrudate is caused to discharge extrudate. A cutter mechanism is provided at the outlet of the conduit severing the extrudate repeatedly at a rate determined by the advance/retraction of one of the hydraulic ram extruders to form blanks of substantially equal volume.

摘要： An accumulator head for blow molding machines having a diverter sleeve that cooperates with other components in the head to form annular concentric flow paths for plastic material between the inlet and outlet of the diverter sleeve to divide the plastic material into two arcuate paths which subsequently meet and split into two more arcuate paths in which plastic material flows in a reverse direction relative to the first two paths and is directed to the diverter outlet. The diverter sleeve thus insures intimate mixing of the plastic material and eliminates the likelihood of a weld line in the plastic material. In addition, the diverter sleeve is mounted for up and down movement with respect to the inlet for plastic material to thereby eliminate dead points in the plastic flow path and facilitate changeover from one material to another in the head.

摘要： Disclosed are apparatus and a method for forming multi-directionally oriented plastic articles by shearing a thermoplastic material in a non-linear shear pattern while the material is at a temperature conducive to orientation and further processing the material by known plastic forming techniques to form an article in which the material remains oriented. More specifically, thermoplastic material is plasticized and accumulated in an amount at least sufficient to form the article, and the material is expressed under pressure from the accumulated body to and through an orifice. The material is non-linearly sheared prior to its issuance from the orifice to induce orientation stresses into the material, and, during shearing, the material is at a temperature which is conducive to orientation. The orientation stresses are frozen into the material when the material is formed to a desired configuration exteriorly of the orifice by known plastic forming techniques, such as blow molding, injection molding, compression molding, thermoforming and the like. During such forming, additional orientation stresses may be induced in the material and superimposed upon those stresses previously introduced thereinto.

摘要： A method of forming a shaped article from non-melt fabricatable, high temperature, polymeric (polyimide and polyamide) resins, using an apparatus including a die with compaction, back pressure and relief zone. Such resins are ram-extruded at a temperature of between about 20.degree. C. and 400.degree. C., but below the second order glass transition temperature of the resin to form a shaped article, followed by heating at a temperature above about 250.degree. C. for a time sufficient to coalesce the resin. Such method and apparatus is particularly well-suited to produce close tolerance articles of precise dimensions, such as rods and tubes.

摘要： A molding apparatus, using raw material substantially comprised of crumbed rubber tires, and producing end products of durability and structural integrity. Products such as fence posts and dimensioned pieces like dimension-lumber products, have a hardened, dense outer wall structure surrounding a comparatively less dense and relatively porous central core, with the attendent structure integrity advantages of tubular and hollow-walled products. Heat fused raw material is fed under pressure, as from a screw extruder mechanism, through selectively controlled input valves to mold bodies, with the mold bodies carried in a chilled environment to establish fluid flow paths and hardening sequences leading to the desired end product body structure.

摘要： An extrusion apparatus especially suitable for the extrusion of ultra high molecular weight polyethylene comprising an elongated die having internal heating and cooling temperature control units. The die comprises one piece straight through construction and incorporates a chamber that is positioned in longitudinal alignment with the die profile zone. The ratio of cross sectional areas of the chamber and of the die profile zone is substantially one to one. A punch forces the polyethylene through the chamber and into the profile zone of the die wherein the resin is cured and extruded to the desired shape. Internal heating passages and cooling passages are positioned within the die to form a temperature gradient wherein the temperature is greatest at a point intermediate the ends of the die. The travel of the extruded shape is retarded by an adjustable clamp exteriorly of the die.
