Abstract: ABSTRACT            The invention relates to a method and apparatus for at least partial automatic control of the operating cycle of a hydraulic excavator, more particularly an excavator having a flapped shovel or dipper, for loading bulk material onto heavy trucks.  The concept of the invention is to store data relating to a manually executed operating cycle and then to repeat the cycle automatically upon call-up.  To this end it is proposed to fit angle potentiometers at all pivot points in the excavator elements, the measurements obtained from the said potentiometers being passed, through an amplifier if necessary, to an electrical calculator comprising a memory from which the stored values converted into signals may be fed in a specific sequence, to electro-hydraulic valves for the purpose of controlling the cycle.  The invention makes it possible to achieve substantially greater productivity from an excavator in that a plurality of automated movements may be carried out simultaneously.  At the same time, the pressure on the excavator operator is relieved which also increases productivity.

Abstract: ABSTRACT OF THE DISCLOSURE           A material injection assembly of the type for injecting a resin material into a mold cavity including a body member defining a nozzle for injecting material into a mold and including at least one central channel for conveying a first material through the nozzle.  The assembly is characterized by an internal purging mechanism for closing the nozzle to the mold while allowing the flow of purging material between the channel supplying resin material to the control channel and a debris channel.  The purging mechanism further allows flow of purging material between a separate purging material channel and the debris channel to perform a post-purge function.         A cooling system is also disclosed which provides a coolant supply channel which bifurcates into two channels about the central channel proximal to the nozzle to provide maximum cooling at the portion of the assembly closest to the mold.

Abstract: ABSTRACT     A fillration membrane, especially adapted for use in hemofiltration as well as filtration of infusion solu-tions.      The membrane, in the form of a hollow fiber, is made of a polymer which is soluble in a polar, non-protonic organic solvent. The most preferred polymer for the membrane material is polyamide. Characterizing for the membrane is high ultrafiltration rates (permeabilities to water) of up to 500 x 10-4 m1/sec. x cm2 x atm., and impermeability to albumin (Mw 68,000).      The membrane is prepared by extruding a polymer solution with a center liquid under conditions such that the volume of polymer solution to volume of center liquid ratio is within the range of from 2:1 to 4:1. Simul-taneously, the inner diameter to wall thickness ratio of the hollow fiber is preferably correlated to the polymer concentration and is set to 150:75 to 280:75 at a polymer concentration of 5 - 20%. The most preferred such cor-relation is 220:75 at a polymer concentration of 11%.
