Abstract: Abstract of the Disclosure A system using a sorting network to intercouple multiple processors so as to distribute priority messages to all processors is characterized by semaphore means accessible to both the local processors and the global resource via the network.  Transaction numbers identifying tasks are employed in the messages, and inter-faces at each processor are locally controlled to establish trans-action number related indications of the current status of each task being undertaken at the associated processor.  A single query to all processors via the network elicits a prioritized response that denotes the global status as to that task.  The transaction numbers also are used as global commands and local controls for the flow of messages.  A destination selection system based on words in the messages is used as the basis for local acceptance or rejection of messages.  This arrangement together with the transaction number system provides great flexibility as to intercommunication and control.

Title: Pulse width modulated inverter for unbalanced and variable power factor loads

Abstract: Pulse Width Modulated Inverter for Unbalanced and Variable Power Factor Loads Abstract An n-phase inverter for developing polyphase AC power from DC power developed by a DC source over first and second DC bus lines and a neutral line includes cir-cuitry for preventing the return of regenerative currents developed by a load connected to the output of the inver-ter to the DC source.  The circuitry includes means for sensing  the  presence  of  regenerative  currents,  and switches which are operated when a regenerative current is sensed to disconnect the DC source from the inverter and to shunt the regenerative current back to the load. The inverter may therefore by used with DC sources which cannot accept regenerative currents.   Furthermore,  the size of a DC bus filter between the DC source and the inverter may be substantially reduced.

Abstract: Abstract of the Disclosure A technique is disclosed for detecting the presence of larger amplitude signals in a signal having both smaller and larger amplitudes.  The signal is peak detected, after which the valleys of the peak detected signal are valley detected to provide a valley detected signal.  The level of the basic signal relative to the valley detected signal is altered by decreasing the former or increasing the latter, e.g., by a ratio of 1:2 or 2:1 respectively, and the resulting signals are compared to produce an output when the level of the former exceeds the level of the latter.  The technique can be used in a hands-free communication system to detect voice signals in a signal containing both noise and voice signals.

Abstract: Abstract:            Constant   temperature   heating   value  measurement apparatus An apparatus for determining the heating value of a fuel gas stream of variable composition utilizes a housing of high thermal conductivity defining a small volume combustion chamber, and filled with a bed of highly thermally conductive particles surrounding an electrical-resistance heater.   The heater  maintains the  internal  temperature  of the  chamber  above the combustion point of the fuel gas, to totally combust the enclosed sample.  The bed of particles transmits the heating effects of the combustion to the housing. A temperature sensor attached to the housing communi-cates with a feedback controller which acts to main-tain the housing temperature constant,  by appropri-ately adjusting the electrical energy supplied to the heater.  Means are provided to correlate changes in the electrical energy to the heating content of the fuel sample.

Abstract: ABSTRACT OF THE DISCLOSURE            A process is disclosed for ion nitriding an article made of aluminum or an aluminum alloy.  The article is disposed in a sealed vessel and the oxygen gas in the vessel is removed.  The surface of the article is then heated to a prescribed nitriding temperature, and the surface of the article is activated to facili-tate the formation of an aluminum nitride layer by the subsequent nitriding treatment.  Thereafter the article is subjected to ion nitriding, thereby forming an aluminum nitride layer having excellent wear resistance and high hardness.  This ion nitriding treatment for aluminum material can be carried out at temperatures lower even than a solution treatment temperature of aluminum material.

Abstract: ABSTRACT OF THE DISCLOSURE      Described is a slagging coal combustion system suitable for retrofitting boilers, furnaces and industrial-process heat generators originally designed to burn oil or gas.  It comprises a fluid-cooled primary combustion chamber into which oxidizer and fuel are injected to provide high-velocity rotational flow combustion zones such that the fuel is burned substoichiometri-cally, while in flight, with up to 90% of the ash being removed as molten ash.  A swirling mixture of combustion products passes from the primary chamber to an expansion chamber where more slag is removed and the gaseous products are passed upwardly and thence to an end-use equipment, such as a boiler or industrial furnace.  As the gaseous combustion products arrive at the interface with the end-use equipment additional air is mixed with the hot, relatively clean, gaseous products from the combustion system.  Final combustion takes place, therefore, in the end-use furnace, boiler or kiln.  Subsystems for injecting fuel and oxidizer into the primary combustion chamber are independently controllable so that the substoichiometric combustion conditions may be regulated to simultaneously minimize nitrogen oxides (NOx), maximize separation of noncombustibles as molten slag, avoid carryover of soot and assure durability and combustion stability.  The apparatus is constructed and arranged for injection of sulfur sorbents into a fuel-rich portion of the combustion zone thereby enhancing capture of sulfur compounds in the slag.  A coal-fired precombustor subsystem feeds partially -vitiated air to the primary combustion chamber, as its sole supply of oxidizer, at any selected temperature within the range from about 1200°F to about 2000°F.  The stoichiometry of this precombustor and the velocity and mass-flow rates of its output stream are independently controllable.

Abstract: Abstract of the Disclosure A sleeve-type beverage can carrier having end dust flaps which mechanically interlock by means of locking tabs and cutouts.  The flap containing the cutouts overlaps the flap containing the locking tabs so that the cutouts and tabs are aligned.  The locking tab is folded back to allow the flap with the cutouts to be moved into place, then is inserted through the cutout and also through the portion of the bottom flap from which  the locking tab was  struck.   This provides  a secure mechanical lock.   In  addition,  the  blank  from which  the  carrier  is formed  is designed so that the space between dust flaps is identical in shape to that of the dust flaps. This allows multiple widths of blanks to be cut from the sheet stock without scrap loss.

Abstract: Abstract of the Disclosure In a hydraulic breaker, oil pressure at a fixed value always flows in the low pressure circuit whenever the piston is raised or lowered.  This avoids the need for an accumulator in this circuit.  At the same time, a quantity of the high pressure oil is required for each of the rising and falling movements of the piston, which brings about less change in surge pressure, again resulting in no necessity for an accumulator in the high pressure circuit.  The breaker also has an increased striking force, because, when the piston is lowered to strike the chisel, the high pressure oil is used as well as the reaction force of compressed gas.
