Abstract: ABSTRACT OF THE DISCLOSURE       A  data  processing  system  includes  a  central processing subsystem, a main memory  subsystem, and a  number of peripheral subsystems including a  communication  subsystem all  coupled  in common to a system  bus.  Subsystems  communicate with each other during asynchronously generated  information bus transfer cycles.          Each one of the subsystems  receives information by providing any one of three  signal responses  including  a  positive acknowledge signal indicating an  immediate response,  a negative acknowledge signal indicating  that the unit will most  likely be busy for an extended period of time, and a quasi-negative response indicating that  the   unit  will   probably  be   ready   during  the  next asynchronously   generated bus  transfer   cycle.   In  order  to expediate the  response  in the  case of  the  transfer over  the system bus of an  input/output order from  the central processing subsystem to  the   communication   subsystem,  apparatus in  the communication system stores a positive acknowledge or a negative acknowledge signal for each communication channel.  The signal is set  to  indicate a   negative   acknowledge  when  the  previous input/output order  filled the last  communication control block.          The signal  is set to  indicate a  positive  acknowledge when the previous  input/output  order emptied  the  communication control block.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for gasifying cellulosic material comprises feeding cellulosic material into the uphill end of an inclined rotary kiln; transporting a bed of cellulosic material through the kiln and continuously tumbling the bed; withdrawing fuel gas from the uphill end of the kiln so it flows countercurrent to the bed and removes moisture in the drying zone and thermally decompose volatiles in the devolatilization zone; admitting air overbed in the devolatilization zone and only underbed in the gasifying zone, and controlling the mass flow rate of air into the devolatilization and gasifying zones respectively as predetermined percentages of that rate of which is stoichiometric to the cellulosic material fed into the kiln to thereby limit temperature rise, present agglomeration and minimize entrainment of solid articles.  Air is admitted into the gasifying zone underbed through axially spaced sets of shell ports, and the mass flow rates of air  therethrough are regulated as a function of the percentages of carbon in the bed in the portions of the kiln in which the sets of shell ports are disposed to thereby efficiently utilize the air in converting carbon into CO2, a sure that a high pressure of CO2 is converted into chemical energy in the form of CO, and permit shortening of the kiln.

Abstract: APPARATUS FOR METERING SEMI-FLOWABLE MATERIAL                ABSTRACT      A multistage volumetric feeder has a storage hopper for storing a mass of semi-flowable material, such as strand fiberglass, asbestos, or titanium dioxide.  The material is bottom unloaded and passed through several stages of pressure reduction, aeration, and conditioning to loosen the material and place it in a state of substan-tially constant density.  The conditioned material is further prevented from bridging and compacting as it is volumetrically delivered to a metering stage through a segregation stage.  Because the semi-flowable material is placed in an uncompacted state of substantially constant density, the feeder is capable of delivering a precise mass of material over a wide range of flow rates.

Abstract: ABSTRACT         A community office switching system includes a three-level hierarchy of distributed processors operating in parallel with one another.  At the highest level, a stored-program call control processor controls call progression, establishing paths through the matrix switch network.  At the second level, a ser-ies of special-purpose, stored-program, port control processors each service 1,024 ports, sensing and transmitting supervisory signals and communicating the occurrence of significant port events to the call control processor.  Each port control pro-cessor dedicates approximately 32 microseconds out of every 32 milliseconds to each of the 1,024 ports in time-multiplex fash-ion, and hence no port can ever be locked out at the port-con-trol-processor level.  One from a series of stored programs is executed to service each port precisely once every 32 millisec-onds.  At the lowest level, a digital filtering processor, as-sociated with each port control processor, samples some signals from each port once every millisecond, filters the sampled sig-nals to give one filtered sample every four milliseconds, and stores the filtered samples for presentation to the associated port control processor once every 32 milliseconds.

Abstract: 21                  48,443 ABSTRACT OF THE DISCLOSURE Each customer location is equipped with a remote terminal which contains a role code identifying the remote terminal  as  an end device  and a plurality of  address codes.  A plurality of signal repeaters are each connected with certain of the remote terminals through a distribu-tion network.  Each signal repeater contains stored route and role codes as well as a unique address code allowing each signal repeater to be additionally addressed as an end device.  A central station produces an outgoing com-munication signal intended for at least one end device.  A communication  link couples the  central  station  to  the power  distribution  network.   The  communication  signal includes a route code identifying a signal path to the end device,  a role code identifying the first device in the identified route,  an address  code  and a message code. Upon  receipt  of  the  communication signal by a signal repeater which is not the intended end device, the receiv-ed route and role codes are compared to the stored route and role codes.  If there is a match, the signal repeater removes  its  role  code  from  the communication  signal, inserts the role code of the next device in the identified route and retransmits the signal.  The signal is continu-ally modified and retransmitted until the message code is received by the intended end device.

Abstract: ABSTRACT OF THE DISCLOSURE:         The inflationary tenedencies which have prevailed throughout the world for years and the considerable increase of transactions effected with the aid of machines for vend-ing merchandise and services, have resulted in a need for coins having a high value.  Public authorities who are re-sponsible for the coinage often consider the use of smaller coins for this purpose.  These coins should differ in color from the most valuable existing coins.  Particularly gold colors are suitable for this purpose.  For this reason there is a demand for a gold-colored material which can well be processed to make coins by casting, rolling and stamping and has a high resistance to tarnishing so that it retains as long as possible the original gold color.  Thus in accordance with the invention coins or the like can be made from a copper-base alloy which contains 1 to 7 % tin and 1 to 7 % aluminum and contains aluminum and tin in a total not in excess of 10 %, balance copper and inevitable impurities which are due to the manufacture.

Abstract: METHOD OF MANUFACTURE OF TAPERED WOOD I-BEAM     Abstract of Disclosure A method of manufacture of a tapered wood beam, such as an I-beam, is described.  With such method an I-beam of uniform width including a web member of uniform width and a pair of first flange members attached to the opposite sides thereof, is first produced and then cut into two portions by  sawing the web member of such beam along a diagonal line to form two tapered web members each attached at one side to a first flange member.  The resulting I-beam portions are then assembled by releasable fastening, such as clamping, the first flange members together in back to back relationship so that the sawn edges of the tapered web members are facing outwardly and parallel to form an assembly of substantially uniform width.  This assembly is then fed through an automatic I-beam manufacturing machine, which may be the same machine in which the uniform width I-beam was produced, to fasten a pair of second flange members to the sawn edges of such tapered web members resulting in the production of two interconnected I-beams of tapered width.  The two tapered I-beams are separated by unclamping the first flange members from each other.

Abstract: ABSTRACT A process instrument, of the type having a movable indicator to represent the magnitude of a process condition, has its motive power supplied by a relatively high-speed steeping motor.  The motor is servo-controlled by a feedback circuit, including a potentiometer coupled to the indicator drive mechanism, which develops a feedback signal corresponding to the indicator position.  The system is arranged to actuate the motor immediately upon develop-ment by a circuit of a deviation signal outside of a fixed deadband, but the extent of initial motor movement is limited to a pre-set small amount (prefer-ably one step).  If the deviation signal still is outside of the deadband after a predetermined period of time, a clock pulse oscillator is turned on to actuate the motor at a relatively rapid rate until the deviation signal returns to the deadband.  The instrument also includes special limit circuitry for preventing motor activity when the pen has been driven to either end of its full-scale stroke.
