Title: Multicolor display device using  electroluminescent phosphor screen with  internal memory and high resolution

Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure utilizes a memory electroluminescent (EL) layer which has brightness-voltage (B-V) characteristics with multistable hysteresis loops of one color emission.  Another EL layer of second color emission is incorporated therewith for a multicolor display device.  The device comprises the two EL layers fabricated in sandwich form separated from each and from the electrodes by insulating layers which are inserted for breakdown protection and isolation of the two EL layers.  Certain insulating layers may be omitted if the two EL layers are made of compatible materials and the hysteresis characteristics are not affected.  In steady operation, an AC voltage signal is applied to the sandwiched device to maintain a display characteristic.  A superposed switching voltage or electron beam or light beam is used to trigger a desired display.  The displayed image may be erased by reducing sustaining AC voltage below threshold value.  The principle of this disclosure may be generalized to three or more layers so that greater flexibility of color choice is obtainable.

Abstract: ABSTRACT            CONTINUOUS WEB SUPPLY APPARATUS       An apparatus for providing a continuous supply of web material to a web printer or other system.  It is necessary to achieve this so that a printing operation, for example, may continue in uninterrupted fashion even as successive rolls of printing paper or other web material are depleted.  The web material is fed from a first roll (36) supported in a feed posi-tion, and when the first roll is near depletion, the leading end of a second roll (36) is adhesively connected to the web of the first roll with that web then being severed.  One belt drive means (48) is employed for rotating both the forward and rearward rolls so that these achieve the same speed for the connecting and severing operations.  The belt drive means are connected to the press drive through control means (73) which vary the belt drive speed in accordance with the tension of the web.  An indexing conveyor (30, 32) supports forward and rearward rolls to locate the rolls in the forward and rear-ward running positions and in intermediate positions for con-necting and severing of the web material and for loading of new rolls into the system.

Abstract: SURGE ARRESTER HAVING COAXIAL SHUNT GAP         ABSTRACT A surge arrester of compact construction includes a housing formed preferably  of elastomeric material through which a pair of spaced terminals protrude and between which a stack of metal oxide varistor discs is disposed and connected in series therewith.  Disposed below the lower one of the discs and in contact there-with is a conductive base plate and an electrode is spaced somewhat from the lower surface of the base plate to form a gap and is provided with shunt means connecting the electrode with the upper surface of the lower disc so that an overvoltage surge condition and the resulting arc across the gap establishes a shunt circuit around the lower disc.  Thus the lowermost disc is effectively shunted during surge conditions thereby enhancing the protective response of the device while the lowermost disc is in the circuit during stabilized conditions and effectively increases the overall resistance of the arrester and by this means limits the magnitude of current and prevents undesirable overheating and the attendant run away tendency of the arrester. Since the elastomeric housing is in direct heat trans-ferring contact with the stack of varistors, heat transfer to atmosphere is greatly facilitated.

Abstract: ABSTRACT OF THE DISCLOSURE         A group operated circuit disconnect apparatus for overhead electric power lines has a base in the form of a box-like housing which mounts on a pole, an upright shaft extends through the housing, and a transverse shaft also extends through the housing.  A linkage is mounted on the shafts in the housing so that axial rotation of the transverse shaft axially rotates the upright shaft, and this causes three circuit disconnect switches mounted on the housing to be moved simultaneously between closed positions and open positions, or vice versa.  An electric motor driven screw and nut drive subassembly for the transverse shaft is mounted in the housing; and the ends of the housing have removable closure plates for access to the linkage and for removal of the subassembly.

Abstract: KDE 4500.1 Abstract of the Disclosure Apparatus for indicating at a distance the onset of parturition in animals including a radio transmitter and a source of electrical power adapted to be secured to the pre-parturient animal and a rup-turable assembly adapted to be mounted across the vag-inal orifice of the pre-parturient animal.  The rup-turable assembly has a preferred rupture line along which the assembly ruptures when the vaginal orifice distends during the onset of parturition.  A switch, for connecting the transmitter to the source of elec-trical power, is secured to the rupturable assembly on one side of the preferred rupture line.  A magnet holds the switch open while the rupturable assembly is unruptured in order to prevent the closing of a cir-cuit between the transmitter and the source of elec-trical power.  The magnet is secured to the rupturable assembly adjacent the switch but on the opposite side of the preferred rupture line therefrom.  The switch is closed except when in close proximity to the mag-net.  At the onset of parturition the rupturable as-sembly ruptures, separating the switch from the mag-net.  The switch thereupon closes, completing a cir-cuit between the transmitter and the source of elec-trical power, causing the transmitter to transmit a radio signal indicative of the onset of parturition.

Abstract: ABSTRACT         A lightweight muffler and method for muffling a noise component of a stream of gases is disclosed.  Prior art mufflers have not attempted to achieve sound dampening through side-by-side flow of exhaust streams within the muffler to produce sound dampening eddy currents.  In contrast the muffler of this invention includes a chamber in which gases are directed in side-by-side streams flowing in opposite directions.  The side-by-side streams are in contact with each other for the generation of sound dampening eddy currents in the chamber, but such contact does not break down the con-tinuous, low resistance flow of gases through the muffler.          The chamber is advantageously formed as an expansion chamber in which gases:  enter one end of the chamber as an annular stream concentric with the inlet pipe to the muffler, travel along the inlet pipe to the other end of the chamber, are reversed, and travel as a concentric annular stream of greater diameter in the opposite direction down the length of the chamber for discharge into a passageway leading to the outlet tube of the muffler.  A second similarly formed chamber for counterflow of opposed streams and the generation of eddy currents there-between is preferably formed proximate the outlet tube of the muffler.
