Abstract: IMPROVED CARD READER FOR SECURITY SYSTEM        Abstract of the Disclosure There is disclosed herein an improved card reader for a security system utilizing a central controller and a plurality of card readers for controlling traffic through critical doors in a facility.   During normal operation, the card readers read card data and send it to the central controller.   The  central controller makes the decision whether to grant or deny access based upon a comparison of the card data and data kept in memory regarding persons who are authorized access to certain areas.  The central controller then sends a "Go" or "No Go" message,  i.e., whether or not to grant access, to the reader after the access decision is made.   The improved reader includes means for storing the authorized identification code data for persons who will be allowed access during times when communications between the card reader and  the central controller are not working.  There is also disclosed means for  temporarily  storing  transaction  information  for transactions made during periods when communications with the  controller  are  lost.    During  such  degraded  mode operation,  i.e.,  when  communications  with  the  central controller  are  not  working,   access is  granted  to cardholders with the proper system code if their I.D. code data on their cards matches an I.D. code record in a table stored by the central controller in a degraded mode buffer in  the  reader.    The  I.D.  codes  and  times  of  the transactions during degraded mode are, whether "Go" or "No Go", stored in a degraded mode transaction buffer in the reader.      When   communications   are   restored,   the transactions saved in the transaction buffer are sent to the controller.

Abstract: IRON ORE CONCENTRATE TREATMENT SYSTEM Abstract A system  for  providing  thermal  and  chemical energies  for  the  production  of  pelletized  iron  ore concentrates while allowing a reduction of a portion of the material in process.  The material in process is introduced as  ore  fines,  pelletized  and  fired  in  an  indurator  to produce feedstock for reduction by further processing.  A portion  of  the  material  in  process  is  diverted  to  a reduction plant.  The reduction plant provides thermal and chemical  energies  for  the  indurator.    In  a  preferred embodiment, a low temperature plasma generator is employed, either as the reduction plant or to provide thermal and chemical energies for reduction.  When a distinct reduction plant  is  employed,  top  gases  from  such  plant  may  be supplied to the indurator to provide thermal and chemical energies  therefor  and  to  the  plasma  generator  for recarburization thereof.   The material in process may be diverted as ore fines or as fired or unfired pelletized ore concentrates.

Abstract: ABSTRACT A waveguide lowpass filter operates in at least two evanescent modes,  The filter has successive ridges with a space between said ridges.  The ridges are associated with parallel capacitance and a space between them is associated with series inductance  in the TE10 mode.  Each ridge is top-loaded so that series capacitance can occur in a TM11 mode in parallel to said series  inductance.  The filters of the present invention can be made smaller than previous evanescent lowpass filters and can achieve improved results.

Abstract: ABSTRACT           An apparatus for producing multiple ribbed, spiral seamed pipe from a metal strip thinner than 29 gauge is disclosed.  The apparatus includes the conven-tional elements of a frame, a drive roller for feeding the strip through the frame, a flange'roller and fold-ing finger for bending the outer edges of the metal strip, a forming head for forming the strip into a pipe so that the outer edges of the strip mate, and a clinch-ing roller and contra roller for compressing the mated edges to produce a spiral seam.  The present invention improves this conventional apparatus by providing only two pairs of edge forming roller assemblies that co-operate to bend the left edge of the strip perpendicular to the strip, and the right edge of the strip into an upward facing, V-shaped channel with its outer edge perpendicular with respect to the strip.  Five pairs of corrugation rollers are mounted on the frame adjacent to the edge forming roller assemblies.  These corruga-tion rollers cooperate to form three continuous, open-channel corrugation grooves in the metal strip.  Each succeeding corrugation roller pair forms the corruga-tion grooves deeper and narrower than the preceding pair.  Three pairs of squeezer assemblies are mounted in the frame adjacent to the corrugation roller means to squeeze together the sides of the corrugation grooves to produce three parallel support ribs for the pipe.

Abstract: ABSTRACT       A gas bearing system for a piston 24 of a linear compressor 20 in which gas from the piston head space 26 is injected into a high pressure reservoir 106 within the piston when the working fluid in the piston head space is at high pressure.  In one embodiment, gas from a low pressure reservoir 104 is exhausted into it when the piston working space fluid is at low pressure.  Gas flow is directed between high pressure and areas of low pressure during operation of the piston.  This gas flow is directed between the piston and its surrounding sleeve 30 in a manner which holds the piston 24 in suspension away from the sleeve 30 to thereby reduce the friction and wear experienced by the piston and sleeve.

Abstract: DEVIATION HOLE PLUG            ABSTRACT OF THE DISCLOSURE       Prior art devices all include central apertures formed in the flat central portions with flexible fingers radiating from the centre portion.   The wings or fingers are  not  strong enough to maintain the plug in position against the force of seismic explosions, the force of which is absorbed by the flat base and the apertures often give way when the plug is forced down the hole by the conven-tionally used pole.   Furthermore,  when back filling  the plugs, soil and the like often sifts down through the hole.          The present device includes ribbed wings for strength and a  cone-shaped  solid  base  to  facilitate  positioning  and to absorb and deflect explosive forces.
