There is disclosed an improved gaseous discharge display panel device and process of manufacturing same. A large number of cathode substrate electrode and mask structures are printed and fired on a single glass sheet, the electrodes being printed first and dried/cured at a higher temperature than subsequently applied mask and electrical crossovers, which are cured at lower temperatures. Upon completion of fabrication of the electrode and dielectric mask structures and crossover connections, the ...

A high speed scanning system and method for scanning a matrix of alarm condition sensing means. A clock-fed counter means and decoder means automatically scan the matrix line by line. When a sensing means which has turned on due to the detection of an alarm condition is sensed the scanning means automatically stops scanning and a readout of the matrix position of the triggered alarm sensing means is provided. The scanning operation may be controlled in either an automatic mode by a central porce...

There is disclosed an improved gaseous discharge display device having segmented electrodes, typically cathode electrodes, shaped in the form of segments of characters to be displayed, a viewing plate carrying an opposing electrode, typically an anode electrode, there being one such anode electrode for each character position to be displayed and a seal sealing the electrodes and a gaseous medium at glow discharge pressure therein. The cathode electrodes are a sputter resistant material selected ...

A non-thermionic gas discharge system with spaced electrodes in a light transmissive envelope, a DC power source, a solid state switch connected between the electrodes and the DC power source which outputs a high-frequency alternating current square-wave voltage, and a circuit connecting the switch to the electrodes such that the square-wave voltage at the electrodes reverses polarity faster than the electron pattern in the envelope can shift.

An earpiece assembly for use in a stethoscope having a pipe member includes a connector having a distal end coupled to the pipe member and a proximal end, a bushing having a distal end rotatably coupled to the proximal end of the connector and a proximal end, and an earpiece having a sound path and being coupled to the proximal end of the bushing. The earpiece assembly may further include a bearing for rotatably coupling the connector and the bushing. The earpiece assembly provides a stethoscope...

A hot stick switch head for a lineman's tool for safely and expeditiously removing and installing fuseholders having a tubular body and a mounting assembly from an overhead mounting comprising a base member having a downwardly depending attachment device for attachment to the end of a hot stick and an elevated slot member on the opposite end thereof for receiving an element of said mounting assembly, and a fusebody-receiving notch. A laterally projecting arm engages a fusebody anywhere along the...

A roadway vehicle sensor includes a coextrusion having a linear conductive section and a linear non-conductive section forming a vehicle deformable closed housing. The linear conductive section has an inwardly projecting conductive plunger along the length thereof which is fused to wedge removal arms. The linear non-conductive section has a pair of inwardly projecting insulating wings having wing tips spaced apart a distance defining a plunger gap. The insulating wings also define a contact cham...

There is disclosed an article sorting apparatus and method wherein articles bearing a manually marked code in a grid or code area locatable by one or more guide elements which may be separate and distinct from the manually marked code. For postal articles, such as letters and the like, the code may be the zip code, preferably associated with a unique postage stamp, also disclosed herein, marked on a grid by dots, circles, line X or like optical marks. On passing through a reading station, the ar...

The light bulb socket burnishing tool is a device used to remove surface corrosion from the interior of common light bulb sockets without their removal from a base, restoring to operation and extending the life of the socket.

A policing technique for a telecommunications traffic of variable length packets is described. The technique uses a plurality of police engines, grouped in pairs. A selection module selects a police engine pair to process a packet. Each police engine contains a conformance unit, credit unit and a debit unit, in which the credit update of one police engine influences the credit update of the other police engine in the pair. The technique also uses a combinatorial function to decide on a category ...
