Abstract: ABSTRACT        A multi processor system in which processors communicate via a bus with ordered access of the processors to the bus.  After receipt of a trigger signal each triggered processor times its access to the bus dependent on its unique code (which may be its address) and the function the processor is to perform.  In a special case in a first phase several processors transmit information along the bus in a queued manner to a receiving processor which infers the processor transmitting the information it is reading from the time lapse from the trigger signal; in a second phase a processor transmits information onto the bus in a queued manner and each receiving processor by timing its reading of the bus reads the information intended for it.  An application of the invention in intra-shelf communication in a private branch telecommunications exchange is described.

Abstract: ABSTRACT           AN IMPROVED VALVE COMPONENT     The invention relates to an improved valve component such as a spring or cushion plate or, in particular, a valve plate for a plate-type non-return valve wherein the flexing action, performance and reliability is improved by formation of flexible guide arms each having a central axis extending as a continuous curve, preferably a spiral, and extending at continuously increasing distance from the center of the plate to thereby minimize stresses therein which hitherto occurred with known plates having straight portions leading via an angled portion to arcuate portions concentric with the center of the plate.   An advantageous effect is achieved according to another aspect of the invention wherein the resilient or flexible guide arms of any desired shape, each preferably having a spiral portion lead to a radially extending portion, which each bisects a valve closure and joins therewith in a peripheral region to provide added length therefor;   said valve closure preferably having portions extending radially inwards.

Abstract: ABSTRACT            A baseband adaptive equalizer for digital signals, particularly suited to very high transmission rate tele-communications systems, permits compensation for time variant distortions occurring in the transmission channel. The equalizer uses a transversal filter, the coefficients of which are continuously updated according to an adaptive procedure based on sampling of the incoming signal.  The coefficients are selected to be powers of two so that they may be applied by simple shifting in a shift register in-stead of by conventional multipliers.

Abstract: Inverter Control System For Providing An Easily Filtered Output Abstract An inverter control system for selecting an angle set defining an inverter output waveform in response to various operating conditions of the inverter.          The inverter control system selects an angle set in response to signals representing the power factor of the load and the normalized DC bus voltage to minimize the harmonic content of the inverter output waveform and to compensate for voltage drops occurring between the DC power supply and the load.  The inverter control system is also responsive to the inverter filter output current to detect fault conditions and in response thereto, to select at least one angle set defining a waveform to reduce the voltage at the load to zero while allowing the filter output current to increase to a given percentage of the rated current.

Abstract: ABSTRACT         An integrally molded, unitary, plastic dispensing closure comprising a body, a lid, and a "living" hinge that joins the lid to the body.  Cams and cooperating wall surfaces in the vicinity of the hinge provide forces that temporarily deform the hinge, within its plastic limits, and facilitate the movement of the lid to either an opened, or a closed, position.  In one embodiment, recesses are formed at the rear of the closure body to accommodate the cams when the closure is in its closed position.  In another embodiment, recesses are formed in the skirt of the lid to accept upwardly extending posts, and a cavity is defined in the upper surface of the closure body to accept cams, or lugs, depending below the lid.  An efficient, anesthetically pleasing, low profile dispensing closure is achieved in each instance.

Abstract: A B S T R A C T            A hollow rotating body, a rotor, of a refractory material, with holes in the bottom and the side wall, is caused to rotate immersed in molten metal.  The metal inside the rotor is thus caused to rotate. As a result of this, the metal flows into the rotor from the hole in the bottom and out through the holes in the side.  The metal in the rotor acquires the surface of a paraboloid of revolution.            The shaft for the rotor is hollow.  Through this shaft there is intro-duced a fixed electrode.  With the molten metal as the other electrode, an electric arc can be struck between the fixed electrode and the paraboloid surface of the metal inside the rotor, whereby heat is imparted to the metal.  The fact that the surface is continuously changing makes it comparatively simple to strike the arc with a plasma burner.  The apparatus can also be used for alloying and/or refining the molten metal.

Abstract: ABSTRACT OF THE DISCLOSURE          The  process  for  manufacturing materials, in the form of sheets, foils or webs, comprised of chemically, mechanically and/or electrochemically roughened and anodically oxidized aluminum or an alumi-num alloy, which process is performed with a hydrophi-lizing  post-treatment  step.    In this  post-treatment step, a supported aluminum oxide layer is treated with an  aqueous alkali metal  silicate solution which also contains alkaline earth metal ions.   Treatment of the aluminum oxide layer is accomplished by means of an immersion  or   electrochemically.     Electrochemical roughening  is performed  in an  aqueous  solution con-taining nitric acid.

Abstract: BANDSAW JOINT            ABSTRACT OF THE DISCLOSURE           The invention provides a disconnectable band saw joint assembly for connecting together in axial alignment end portions of a bandsaw. The joint assembly does not require welding, and as such can be easily separated to permit threading of the bandsaw through a hole drilled in a plate to permit sawing of a closed ended cut or loop within the plate. This eliminates the normal practice of breaking and rewelding a band saw for cutting a closed loop within a plate. Furthermore, because the joint is cold, it does not affect temper of the saw portions adjacent the joint. The assembly has male and female connections, the female connections having a neck recess and a head recess, and the male connection having a head portion and a neck portion which fit within the neck recess and the head recess respectively. The recess has at least one main recess edge, and the head portion has at least one main head edge, both edges being disposed normally to longitudinal axis of the saw. When the saw joint is under tension, the main head edge is in direct edge-to-edge contact with the main recess edge to permit limited hinging between the end portions about a main hinge axis coincident with the main edges and disposed normally to the saw axis.

Abstract: Abstract In a method for decreasing the alcohol content of alcohol-containing beverages, particularly wine or sparkling wine, accord-ing to the reverse osmosis process, extract substances are added to the dealcoholized beverage.  In order to avoid addition of foreign water to the beverage, the alcohol-containing permeate obtained by reverse osmosis from the beverage subjected to de-alcoholization is distilled in a vacuum.  The permeate water pro-duced therefrom is re-fed to the beverage subjected to the de-alcoholization.  The amount of permeate distillate removed from the beverage subjected to dealcoholization by the reverse osmosis and subsequent vacuum distillation, which essentially consists of alcohol, is fed to the beverage subjected to the dealcoholi-zation in the form of water, which has also been obtained by vacuum distillation from an additional beverage.  In this manner, particularly high quality sparkling wine may be produced.
