Granted: 1981-12-01
Abstract: ABSTRACT           A digital communication system is disclosed for communicating among two central consoles and a plurality of local controllers, such as may be used in a radiation and monitoring system and the like.  Communication occurs between each of the consoles and all of the local controllers via dual paths, each of which comprises a bidirectional duplex two wire communication link.  Each path is independent of the other and each extends from one of the consoles to all of the local controllers from opposite directions, thereby forming a unique noncontinuous loop. Command messages from the consoles are processed by all con-trollers and response messages are made by only the addressed controllers and are not processed by other controllers.  Reflected messages in the opposite direction are ignored by all controllers. In the event of a runaway transmitter or other malfunction in a controller, the controller is automatically isolated.  Systematic reconnection via command messages from the console locate the fault or malfunctioning controller and enable all but the mal-functioning controller to be communicated with.

Abstract: ABSTRACT       A modular flooring for installation on a subfloor and a method for producing it is disclosed.  Each modular elongated section is substantially a U-shaped with the cen-tral part of the U being the weight bearing floor section.       A series of parallel slots is formed perpendicular to the elongated dimension, in the weight bearing surface of each floor section.  The parallel slots each are formed having side members which are folded down so as to achieve a slot which eliminates the presence of fractured metal or cutting edges along the weight bearing portion of the floor section.  On one of the supporting side walls of each floor section is punched a pair of slots.  On the oth-er supporting side wall of each floor section is punched a pair of locking tabs.  The floor sections may be placed adjacent one another so that the tabs extending from the side wall of one floor section will interlock with the slots punched in the adjacent side wall of the next floor section.  The interlocking tabs and slots result in easy assembly and positive spacing of arbitrary numbers of the floor sections.       The method of producing a modular floor section has the steps of forming an appropriate piece of sheet metal into a rectangular shape, forming the ends of each of the slots with a press drill by drilling two sets of holes properly spaced in the sheet metal section along a center-line perpendicular to the elongated dimension, between each pair of previously drilled holes, cutting the sheet metal along the common centerline, bending the sheet metal downwardly along the previously made cuts and away from the operative side of the weight bearing portion of the floor section, as a final step the sides of the floor section are formed by bending the edges of rectangularly shaped piece of sheet metal so that each section has sub-stantially the shape of a U.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a system for injection molding plastic using a novel type of sprue gating having a fixed pin.  A heater cast with a lower nozzle portion is spaced from a cavity plate by an insulating air space and a hollow nozzle seal extends across the air gap between the nozzle portion of the heater cast and the cavity plate around the gate.  The hot runner passage from the manifold extends through the heater cast at an angle into the hollow nozzle seal.  The heat conductive fixed pin is centrally located in the heater cast in alignment with the nozzle seal and gate and projects at an acute included angle from the heater cast into the hot runner passage immediately upstream from the gate in a position in which the tip extends towards the gate into the nozzle seal.  The size of pin tip and the axial position of the pin are selected so that the ratio of gate area to the minimum ring area between the inner surface of the nozzle seal and the outer surface of the pin tip through which the melt must flow is from 2:1 to 1:2.  Although the primary source of heat to the runner passage is from the heater cast on the outside, some heat does flow along the fixed pin from the heater cast to the tip to provide an additional source of heat in the gate area to maintain the melt at a more uniform temperature to reduce stringing of the melt.
