Abstract: ABSTRACT A buried junction MOS memory capacitor target device for electron beam addressable READ/WRITE memories is described along with a method of using the same. The memory capacitor target structure comprises a planar semiconductor substrate of various degrees of complexity having a highly conducting coating providing a low resistance ohmic contact to the substrate backside and an N-type planar semiconductor overlayer forming with the substrate topside a bipolar detector junction. An insulating layer overlies the N-type layer and a conducting coating overlies the insulating layer. The device is employed with an electron beam of sufficient energy to penetrate the latter two layers and to produce carrier-pairs in the N-type overlayer. Electrical access to the device is provided by one contact to the substrate backside and one contact to the conducting coating overlying the insulator. Means are provided within the semiconducting portion of the device for limiting the electrostatic potential difference developed across the bipolar detector junction as a result of changes in the potentials applied to the electrical contacts. This may be achieved by fabricating the semiconducting portion of the device to provide for the occurrence of avalanche conduction within the detector junction whenever the reverse polarity potential difference across the junction exceeds a desired value. Alternatively the reach through effect commonly observed in thin base bipolar transistors when the collector-base potential difference exceeds a critical value can be employed to limit the reverse potential developed across the bipolar detector junction. This may be achieved by employing a planar semiconducting substrate comprised by a thin P-type layer overlying an N-type layer. In operation the design affords a means for applying the desired potential differences across the insulator for the various steps of memory operation and also affords a means for developing a desired reverse polarity potential difference across the buried bipolar detector junction for the duration of the read process.

Abstract: ABSTRACT OF THE DISCLOSURE A muting circuit for loudspeakers is operable to dis-connect a loudspeaker from an amplifier immediately upon a power supply being interrupted. The muting circuit incluces an around-zero-volt detection circuit for detecting around the zero volt level of a commercial AC voltage. An RC time constant circuit is controlled by the output of the around-zero-volt detection circuit to either charge or discharge the capacitor in the RC time constant circuit only when the around zero volt level is detected. A threshold circuit is connected to the RC time constant circuit and operates a loudspeaker relay when the charge on the capacitor either exceeds or decreases below a predetermined level.

Abstract: A HEAVY DUTY PNEUMATIC TIRE                    ABSTRACT OF THE DISCLOSURE         An improved heavy duty pneumatic tire is disclosed which includes a carcass ply of rubberized metallic cord fabric that is wrapped around bead cores to form turnups.          Annular apex strips are disposed between the carcass ply and the turnups and abut the carcass ply along their axially inward side.  Reinforcement strips of rubberized metallic cord fabric may be provided.  These strips are wrapped about the bead cores and form radially outward extensions of the turnups.  Enveloping and bonded to the terminal edges of the turnups and the terminal edges of the reinforcement strips if provided, are cushion elements of soft rubber having high restorability.  The cushion elements isolate the terminal edges from the carcass ply and render the bead area and lower sidewall portion of the tire more flexible to inhibit separa-tion of the rubberized cords at the terminal edges.  Likewise, similar soft rubber cushion elements may envelope and be bonded to the edges of rubberized metallic cord plies forming the reinforcement belt for the tread of the tire to prevent separation along the edges of these plies.

Abstract: CONTAMINANT RESISTANT FEMALE CONNECTOR     Abstract of the Disclosure The connector includes a raised ridge that substantially surrounds the opening to a  plug-receiving cavity.  The connector further includes a pivotally mounted cover for the plug-receiving cavity that is biased toward a closed position.  The cover extends into close proximity with the ridge when it is in its closed position and when it is in an in-use position adjacent to the closed position.          In addition, the cover has a depending skirt that overlaps the sides of the ridges when the cover is in the closed and in-use positions.  This configuration of and interaction between elements shields the contacts of the connector from dripping and sprayed liquids and retards the flow of moist and dusty air through the contact region.

Abstract: Abstract of Disclosure A telephone system usable for example in hotels or the like and in which each of a plurality of telephone sets is equipped with a special status indicator or signal light as well as the usual bell, the system being characterized in that the indicator is automatically excited without ringing the bell by voltages applied from the ring generator whose output signal is connected across the tip and ring leads of a telephone line when the latter is placed in a special status (message waiting) by a status signal in the control unit.  The ring generator is constructed to produce special status indicator excitation voltages during the "bell silent" intervals of its output signal, and the indicator is periodically actuated by connecting that output signal across the tip and ring leads of telephone sets, which are in the special status, during at least a portion of such intervals.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a process for automatically controlling the shape of sheet metal produced in a rolling mill, and to apparatus for carrying out the process.  The shape of the sheet is sensed by a shapemeter, and each segment of the shape-meter provides an output indicative of the shape of the portion of the sheet passing over that segment.  In accordance with the invention, the outputs are converted to electrical signal levels, such as current or voltage levels, and certain ones of the signal levels are averaged, and the averages are compared either with certain other signal levels, or with certain other averages.  If the comparisons yield a difference greater than predetermined tolerance levels, control signals are generated to control para-meters of the rolling mill.
