Abstract: ABSTRACT OF THE DISCLOSURE      Oppositely facing surfaces have grooves in one of the surfaces and low coefficient of friction inserts in the grooves.  The inserts have a thickness greater than the depth of the grooves so as to project from the grooves when seated therein for bearing against a facing surface and maintaining the two surfaces in spaced apart relation.  Such inserts provide a reduced friction relation between the two surfaces whereby the two surfaces can be readily rotated between a working condition having a thrust load therebetween and a loosened non-working condition.          Preferably, two or more of the grooves and inserts are provided, the inserts being held in the grooves by dis-torted portions in the walls of the grooves.  The joint assembly of the invention is particularly appli-cable to rock crushers of the type having a threaded connecting joint between a bowl member and support therefor, whereby the low coefficient of friction in-serts provide a liner or spacer which prevents galling of the threads under heavy load and provides for ready rotation of the two members when desired.  The present joint assembly may also be used in association with the threads of a jam nut of a type which locks the bowl against rotation on the support, and furthermore may be used in unthreaded opposing surfaces between the jam nut and the support.

Abstract: S u m m a r y The procedure is intended to make it possible to extract anabolic, respiration-promoting, low-molecular active substances.  The active substances can be used for prophylactic, therapeutic and cell-culture and tissue-culture purposes.  The active substances are obtained from a yeast plasmolysate, by the disintegrat-ion of yeast fungi at the moment of their maximum growth.  The disintegration is achieved by the use of ultrasound under the simultaneous influence of proteo-lytic enzymes.  The residue is subjected to dialysis and very carefully concentrated.

Abstract: Abstract An elongated fluid distributing hose for use in an irrigation system for plants, vegetables, and the like.  The hose incorporates a particular arrangement of a main supply channel for gross water movement, and a water distributing network for fine water movement.  Water pressure reduction takes place in the water distributing network at the point of the passing of the water from the high pressure main supply channel through a series of first fluid-passing openings or inlet stations through one or more smaller fluid-restricting passages.  In certain embodiments, a structure is provided to perform a pressure regulating function in each of the smaller passages.  In one embodiment, pressure reduction between an inlet and an outlet is by way of a serpentine fluid-restricting path.  A novel method and machine are employed to manufacture the various hoses embodying the teachings of the subject invention.

Abstract: Abstract The invention is a stabilizer circuit which allows a ferroresonant power supply to maintain a relatively steady output voltage during input power line transients or interrupts, rapid load changes, or no load conditions without requiring a continuously dissipative minimum load.  In the power supply a saturating transformer 11 is responsive to an input voltage.  A secondary circuit is responsive to the saturating transformer and outputs a regulated voltage.  A stabilization circuit 30 responsive to the regulated output voltage temporarily places a load across the secondary circuit output when the stabilization circuit 30 senses an unstable condition. The stabilization circuit 30 is composed of a sensing circuit 31, a timing circuit 33, a switch T and a load R2.   The sensing circuit 31 senses an unstable condition at the secondary circuit output.  When such a condition is detected, the timing circuit 33 is activated by the sensing circuit 31.  The timing circuit 33 activates the switching means T to place the load R2 across the output of the secondary circuit for a time period determined by the timing circuit 33 and the sensing circuit 31.  The presence of the load R2 brings the ferroresonant power supply out of the unstable condition and returns the regulated voltage output to within an acceptable range.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure relates generally to a computer generated synthesized imaging system.  More particularly, the invention relates to a method and apparatus for providing fast access to a two axis memory wherein consecutive data elements in both row and column orientation of a data set represented as a matrix may be obtained at a rate faster than the access time of memory elements utilized.  A speed-up of access speed by a factor N may be achieved, where N is a power of 2 (2, 4, 8, 16...). The memory elements are organized in N independently addressable banks of data memories.  The matrix oriented data is mapped into these N banks such that any N contiguous data elements of any row or any column reside in different memory banks.  Any N contiguous data elements of any row or column may than be accessed within the access time of any one memory bank.          The N contiguous data elements may then be read from memory in a single memory cycle.  These N data elements can then be multiplexed in the proper sequence into a data stream operating N times faster than the basic access speed of the memory elements used.
