Abstract: SUSPENSION FIRING OF HOG FUEL, OTHER BIOMASS OR PEAT        ABSTRACT OF THE DISCLOSURE A method is described for preparing hog fuel, other biomass, or peat for efficient burning and heat recovery in a water-wall boiler. The process requires drying the fuel to less than a 30% moisture content. The fuel is then pulverized to an upper particle size such that there are substantially no particles which will not burn in air suspension within the confines of the combustion zone. Additionally, the pulverizing step is adjusted such that a fines portion of fuel is created of such size and in such amount that the fines portion readily ignites upon flame initiation. The fines provide sufficient ignition energy so that the entire flow of fuel burns without the necessity of the conventional fossil fuel support or pilot. The fuel is sized to burn in air suspension by injection into the boiler through a swirl stabilized-type burner. For one burner, not particularly optimized for burning wood, a suitable particle size range was found to comprise 65-100% less than 1000 microns and 15-85% less than 150 microns. Pulverizing is carried out preferably at low air flows so that the resulting air and pulverized fuel mixture of about 1-2 kilograms air per kilogram fuel may be directly injected by the swirl stabilized air suspension type burner into the furnace along with secondary air. Combustion in the furnace requires no supplemental or pilot fuel to maintain stability. The process has good load following characteristics having at least a 2.5:1 turndown ratio.

Abstract: APPARATUS FOR MULTIPROCESSOR COMMUNICATION                  ABSTRACT A communication network formed by a plurality of communication processors which are connected together in such a way that messages can be sent efficiently between any two processors in a multiprocessor data processing system is disclosed.  The data processing system consists of a plurality of data processors.  Each data processor is coupled to a communication processor which is responsible for sending and receiving messages from other communication processors which are coupled to other data processors.  The communication processors are organized into a two dimensional hexagonal array. Each communication processor communicates with the 6 communication processors adjacent to it through 6 ports. Each such port couples the communication processor in question to a corresponding port in one of the 6 communication processors adjacent to it.  When a given data processor wishes to send a message to another data processor in the multiprocessor system, it transfers that message to the communication processor coupled to it with information specifying the final destination of the message.  The communication processor sends the message through the appropriate port to an adjacent communication processor.  If the final destination of the message is the data processor coupled to the adjacent communication processor, that communication processor will cause the message to be stored in said data processor's memory.  If the destination is not the data processor coupled to the adjacent communication processor to which the message was sent, the adjacent communication processor will relay the message to a third communication processor which is adjacent to it. The message routing algorithm used by each of communication processors automatically reroutes messages around communication bottlenecks created by a malfunctioning communication processor or by a local communication overload.

Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus for maintaining the weld tip and gas nozzle of a robotic welding apparatus is provided.  The present invention includes a plurality of functional stations at which various operations may be performed on the gas nozzle and/or welding tip In the first station, the gas nozzle is removed from the welding arm and the interior surface of the gas nozzle is cleaned by means of a rotating brush.  In the second station of the present apparatus, a cutter slide serves to pin and shear the weld wire from the weld tip.  The third station of the instant apparatus includes a grinding belt which serves to grind the leading face of the weld tip.  Following the grinding operations of station three, the welding arm may be returned to station one for the reapplication of the gas nozzle and then to station four for the pneumatic application of an anti-spatter compound.  Thereafter, the welding arm may be moved to station five of the present invention which includes a reference block in order that the robot arm may be positioned and welding wire extended therefrom until it contacts the reference block to establish a predetermined length of weld wire extending from the weld tip.          In the event it is desired to replace the weld tip after a prescribed period of operation, following the removal of the gas nozzle and the clipping of the wire from the weld tip, the welding arm is moved to a tip removal and application station.

Abstract: A method and reactor system are described for decomposing organic compounds. A gaseous mixture of organic compounds and water, equal to or in excess of stoichiometry, is passed into a first reaction zone having a temperature range between about 200 DEG  C. and 1400 DEG  C. The first reaction zone has a labyrinthine path which presents organically adsorbent surfaces to the gaseous mixture to provide a residence time in the first reaction zone sufficient to react substantially all of the gaseous organic compounds and the water at high rate. The effluent from the first reaction zone, still with water equal to or in excess of stoichiometry, is then passed to a second reaction zone having a temperature range between about 750 DEG C. and 1820 DEG  C. to decompose the organic compounds remaining in the effluent. The first reaction zone is an annulus which is coaxial with and surrounds the second reaction zone. The labyrinthine path is formed by particulate ceramic material.

Abstract: A connector (15) for assembling two furniture parts such as a tabletop and an associated table leg. The connector (15) comprises a screw (1) provided with a head (2) and a relatively long shaft (3), and a bushing (4)_with outer holding means (5) and a through hole (6). The bushing (4) is pivotally mounted on a smooth part (7) of the shaft (3) and is axially fixed as one terminal surface (8) thereof abuts the head (2) of the screw (1) and the opposite terminal surface (9) thereof optionally abuts a locking means projecting from the shaft (3). One of the terminal surfaces of the bushing (4) comprises a contact knob (11) delimiting the turning of the bushing (4) relative to the screw (1) to an angle less than 350° when it abuts a stop projection (10) projecting from the screw (1). When a table leg and a tabletop are to be assembled the bushing (4) is initially turned into a hole in the table leg by means of a mounting tool. Subsequently the screw (1) is screwed into the tabletop by turning the table leg about its longitudinal axis until it abuts the tabletop and the desired tightening force has been achieved. Then the table leg can be turned backwards an angle less than 350° until the desired positioning of the table leg relative to the tabletop has been obtained and without changing the tightening force therebetween. As a result a tableleg of a cross section corresponding to a triangle can always be secured to a rectangular tabletop and adjusted into its correct position where the right angle of the triangle opposes the right angle of the corner of the tabletop without thereby changing the achieved tightening force between the tabletop and the table leg.
