Abstract: Abstract of the Disclosure A television receiver incorporating telephone interface circuitry permitting the viewer to remotely place outgoing calls by recalling a selected number from memory is disclosed. An infrared link is used for remotely answering incoming calls, initiating outgoing calls and programming a nonvolatile memory with a plurality of preferred telephone numbers for future use. The nonvolatile memory circuit is accessed by means of a microcomputer in response to user-initiated, remotely generated commands. The television receiver's display performs a user interactive function in displaying television/telephone mode operation information, the contents of user-accessed locations in the nonvolatile memory and the telephone number being stored in memory during the programming mode of operation. The microcomputer controls not only the telephone mode of operation of the system, but also television operation in generating digital tune words in response to a channel number entry and providing these tune words to an indirect frequency synthesis type of television receiver tuner. The contents of the nonvolatile memory may be updated, or changed, as desired by user selection of appropriate controls followed by entry of the new telephone number which is presented on the video display as it is entered for user verification. The video display is then cleared upon return to the television mode of operation or upon television receiver turn-off

Abstract: METHOD FOR PRODUCING A GRAIN-ORIENTED            ELECTRICAL STEEL SHEET HAVING            A HIGH MAGNETIC FLUX DENSITY     ABSTRACT OF THE DISCLOSURE      The present invention relates to a method for producing a grain-oriented electrical steel sheet.    A feature of the present invention is to set S ? 0.007%, Mn = 0.08 ~ 0.45%, P = 0.015 ~ 0.45% in a slab.  The present inventive idea does away with the conventional concept of using MnS as an inhibitor.  The present invention prevents incomplete secondary recrystallization by the S content, which is decreased to a level as low as possible.  In addition, a product having a high magnetic flux density can be successfully produced by adding appropriate amounts of Mn and P.  Due to these advantages, a high Si content of a slab, which leads to a watt loss reduction, can also be employed in the present invention.  In addition according to the present invention, the temperature of slab heating, which is carried out prior to hot rolling, can be drastically decreased as compared with the prior art.          Thus, an outstanding cost reduction can be realized due to the decrease in heat energy and complete prevention of the slag formation.  Furthermore, the watt loss of a product produced by a low-temperature slab-heating is considerably lower than a product produced by a high--temperature slab-heating.

Abstract: PARTICLE SEPARATOR SCROLL VANES              ABSTRACT OF THE DISCLOSURE          An inlet particle separator for a gas turbine engine is provided with unique vanes distributed around an entrance to a particle collection chamber.  The vanes are uniquely constructed to direct extraneous particles that enter the engine into the collection chamber and prevent the particles from rebounding back into the engine's air flow stream.  The vanes are provided with several features to accomplish this function, including upstream faces that are sharply angled towards air flow stream direction to cause particles to bounce towards the collection chamber.  In addition, throat regions between the vanes cause a localized air flow acceleration and a focusing of the particles that aid in directing the particles in a proper direction.

Abstract: ABSTRACT            "Impact Sensitive High Temperature Detonator"          An impact sensitive detonator, particularly suitable for the initiation of explosive charges in oil wells, comprises a cylindrical casing closed at one end and open at the other end, the closed end having a thin striking surface which deforms without rupture when struck by a rounded firing pin. The casing contains a primary explosive charge preferably lead azide, adjacent to the closed end, a mass of finely divided refractory material, for example, silicon carbide adjacent to the primary explosive charge and an impact member, extending transversely across the casing and forming with the casing a confined space for the primary explosive charge and the refractory material.  The refractory material and the impact member aid the initiation of the primary explosive charge.  Optionally, a second charge of primary explosive may be placed on the output side of the impact member.  Preferred forms of the detonator contain an output charge of high explosive for example, hexanitrostillbene between the impact member and the open end of the casing.

Abstract: ABSTRACT OF THE DISCLOSURE        A mechanism for cleaning the discharge opening lips of a coating control nozzle by controlled movement of a plurality of brushes transversely along the noz-zle lips.  A carriage is mounted on a support frame and is moved along the frame by a rodless cylinder.  A plurality of brushes rotated by air motors are mounted on one end of a bellcrank which is attached to the carriage and are pivotally moved into and out of engage-ment with the nozzle lips by a fluid actuated cylinder mounted on the carriage. One of the brushes engages and cleans the inside surface of both nozzle lips simultaneously with two pairs of brushes which clean the outside surfaces of both lips as the carriage moves the brushes transversely along the nozzle opening.  A stop is engaged by the bellcrank to limit the pivotal movement of the bellcrank to position the brushes with respect to the nozzle lips.  The brushes may be re-placed with scraper blades mounted on the end of the bellcrank.

Abstract: Abstract of the Disclosure An annulus pressure responsive downhole tool includes a housing having a power piston slidably disposed therein.          First and second pressure conducting passages communicate a well annu lus with first and second sides of the power piston.  A retarding device is disposed in the second pressure conducting passage for delaying communication of a sufficient portion of an increase in well annulus pressure to the second side of the power piston for a sufficient time to allow a pressure differential across the power piston to move the power piston from a first position to a second position relative to the housing.  A pressure relief valve is communicated with the second pressure conducting passage between the power piston and the retarding device for relieving from the second pressure conducting passage a volume of fluid sufficient to permit the power piston to travel to its second position. A back pressure check valve is also disposed in the second pressure conducting passage to provide a continuing but releasable pressure differential across the power piston to releasably hold the power piston in its second position.

Abstract: RAILROAD HOPPER CAR WITH SELF-CONTAINED DISCHARGE SYSTEM     ABSTRACT     A railroad hopper car particularly adapted for ship-ment of dry, granular-like commodities may have its inner space divided into compartments which in turn are formed with chambers.  Each chamber bottom includes a discharge system comprising a pair of aligned fluidizing conveyors which converge downward.  Lower ends of the conveyors are spaced apart to define a chute outlet which includes a passageway through a chute portion of a slide gate dis-charge assembly.
