Granted: 1993-02-02
Abstract: ABSTRACT    This invention relates to a process for producing aluminum-containing strip stock which  is  suitable  for drawing  and  ironing  and  has  reduced  earing.    A continuously-cast,  aluminum-containing  strip  is introduced  into  a  hot-mill  operation  to  provide  a thickness reduction of at least 70 percent with the exit temperature of the strip being minimized.  The strip is allowed to crystallize to form grain having an annealed texture.  This strip is then subjected to cold rolling to reduce the thickness at least 30 percent.   The cold-rolled strip is annealed at an intermediate annealing temperature.   The annealed strip is then subjected to further cold rolling sufficient to optimize the balance between the 45° earing and yield strength.

Granted: 1993-06-15
Abstract: ABSTRACT OF THE INVENTION      A method for using an underground mine communication system to effect minewide communication and an intrinsically safe current limiter circuit for insuring that electrical equipment in the system will not cause incendiary conditions.  The underground mine communication system comprises a plurality of repeaters and medium frequency radios, including mobile, portable and personal-carried radios, coupled to electrical conductors and natural waveguides existing in the earth by tuned loop antennas. Messages transmitted by the radios are carried to the repeaters by the conductors or coal seam waves.  The repeaters amplify, replicate and retransmit the message at two different frequencies for transmission of the message to a surface base station and to other radios in the system.  A paging system, which has a separate set of repeaters, is also coupled to the network of electrical conductors and natural waveguides by tuned loop antennas.  The paging system alerts miners to contact the surface base station. Radios, pagers and repeaters in the system are equipped with the intrinsically safe current limiter circuit to preclude the development of incendiary conditions.  The current limiter circuit comprises a series arrangement of a current trip circuit, a redundant current trip circuit and a current limiting field effect transistor controlled by a feedback control amplifier.

Date Apr. 26, 1984.The present invention relates to a target having conductive fibres in a plurality of beds into which a transmitting/receiving projectile may be embedded with a portion of the projectile remaining protruding from the target. Each bed indicates a score and is electronically insulated from the other. In some embodiments the separate scoring portions of the target transmit different signals with the signal from the projectile embedded in that portion of the target being radiated at a greater strength. The strongest signal (indicative of the portion of the target struck) is received by a nearby receiver and the score displayed. An alternative embodiment utilizes an externally transmitted signal and the projectile acts as a receiving antenna, conveying the signal to only that target bed in which the projectile is embedded and the individual beds are connected to the scoring display system.
