Abstract: An article such, as an electrical connector, for mounting upon a substrate, such as a printed circuit board. The article includes a mounting plane having locating and centering means thereon. The locating and centering means comprises first and second spaced apart, depending lugs, each of which tapers from a first diameter proximal the mounting plane to a second diameter, narrower than the first diameter, distal said mounting plane. The first lug has a longitudinal slot extending its length in a given direction and the second lug has a longitudinal slot extending its length in a direction orthogonal to the given direction. The slots extending in different directions provide a centering and holding response which fixes the connector in position so that subsequent operations may be performed.

Abstract: A double-ended arc discharge lamp includes a sealed, light-transmissive outer jacket, a light-transmissive shroud mounted within the outer jacket and directly supported by the outer jacket, and an arc discharge tube mounted within the shroud. The arc tube is typically a metal halide arc discharge tube. In a preferred embodiment, the shroud includes an outwardly flared portion at each end. The outwardly flared portions space the shroud from the outer jacket and support the shroud within the outer jacket. The outwardly flared portions of the shroud can be affixed to the outer jacket by fusing. The outer jacket can be provided with inwardly extending dimples for locating the shroud with respect to the outer jacket. In another embodiment, the outer jacket includes reduced diameter portions near each end which are attached to the shroud.

Abstract: In a method of preparing an alkaline earth halophospor having an antimony content greater than about 0.70 weight percent, a uniform mixture of starting raw materials is fired with already fired phosphor of the desired alkaline earth halophosphate so that the already fired phosphor is refired in an inert atmosphere containing volatile species from the uniform mixture of starting raw materials.

Abstract: An electric lamp assembly includes a sealed outer envelope, an arc discharge tube mounted within the outer envelope, a safety filament connected in series with the arc discharge tube for extinguishing the arc tube within a predetermined time after the outer envelope is broken, and an electrically-insulating sleeve disposed around the safety filament. The insulating sleeve suppresses emission of electrons from the safety filament and thereby prevents a reduction in frame potential which would increase sodium loss from the arc tube. The insulating sleeve includes openings which permit air to reach the safety filament when the outer envelope is broken. A mounting arrangement includes a pair of mounting tabs which provide electrical connections for the safety filament and which approximately centers the safety filament in the insulating sleeve.

Abstract: An electrical connector with three rows of contacts undergoing right angle bends to form two columns suitable for joining to a printed circuit board. The distal portions of the contacts are retained in a contact receiving wall provided with contact receiving slots equipped with spring back guards. This feature allows the resilience of the contact material to aid in maintaining contact alignment. Provision is made with the connector body to receive an environment sealing compound.

Abstract: A theft resistant security system for motor vehicles. The system has a receptacle with a coupling coil. A surface acoustical wave device associated with the receptacle for relative movement thereto is also provided. The SAW device has a code and its own coupling coil for interaction with the receptacle coupling coil. A testing mechanism is connected to the receptacle for determining whether the code of the SAW device is valid for operation of the motor vehicle.

Abstract: A five pin protector module for telephone circuits comprises two input pins, two output pins and a grounding pin, all on an insulative base. The electrical current path between each input pin and its respective output pin comprises an electrically conductive arm, a current responsive assembly and an electrically conductive helical spring. The module contains a bidirectional voltage sensitive switch which prevents input voltage surges from reaching the output but, instead, conducts them to a grounding member to which the grounding pin is attached.

Abstract: An improved process for producing a translucent polycrystalline alumina body comprising rapid-sintering a prefired compacted green body of alumina of predetermined shape is disclosed. The green body of alumina includes alumina doped with one or more sintering aids. Rapid sintering in accordance with the method of the present invention comprises the steps of raising the temperature of the prefired compacted green body of predetermined shape up to maximum sintering temperature at a heating rate greater than or equal to about 0.1.degree. C./second and less than the rate at which the green body experiences thermal shock; and heating the green body at the maximum sintering temperature for a period of time sufficient to produce a translucent polycrystalline alumina body. The rapid sintering is carried out under a flowing gas mixture of nitrogen and at least about 2.5 volume percent hydrogen.

Abstract: A process for producing finely divided spherical precious metal based powders comprises forming an aqueous solution containing a source of at least one precious metal value forming a solid reducible precious metal material from the solution, reducing the solid material to precious metal powder particles, subjecting the precious metal based particles to a high temperature zone to melt at least a portion of the precious metal based powder particles and cooling the molten material to form essentially spherical precious metal based alloy particles.

Abstract: Apparatus for a signalling system. The apparatus includes a plurality of remote control units each of which is arranged to store self-check timing data therein. This data has a value representing a predetermined period of time the expiration of which corresponds to a predetermined time of day differing from the times of day associated with at least some of the other remote control units. At or following this particular time of day, a self-check operation is initiated for communicating a self-check message, including identification number data identifying the remote control unit, to a centralized communications center. A computer at the communications center receives and processes self-check messages produced by the remote control units and operates in response to each message from a remote control unit to note the identification number data therein and, using this data, to derive self-check timing data for use by the remote control unit in the next self-check operation.
