Abstract: ABSTRACT OF THE DISCLOSURE      An input signal recognition circuit for a control system having an array of momentary  switching elements (hereinafter referred to as "keys") whose number is larger than that of the array of input terminals, which prevents erroneous control system operation which may occur upon simultaneous actuation of a plurality of keys.  The control system with the input signal recognition circuit stably operates against key chattering and noise.   The input signal recognition circuit comprises a key-board including a plurality of keys arranged in a matrix, sig-nals for sequentially sensing the actuation of keys in respective columns of the matrix, an input buffer section which responds to the sensing signals to store the key data keyed in through the key actuation, a memory section for temporarily storing the key data and a recognition section for checking the contents of the memory section to detect whether any key has been actuated and for recognizing whether a plurality of keys in different columns of the matrix have been actuated.  Only when a single key is actuated or a plurality of keys in the same column are actuated does the circuit identify that the input data is effective and generates a given control command  signal in the control system.

Abstract: Abstract of the Disclosure For the combustion of finely-ground coal which is slow to ignite, the coal is preheated before it enters the combustion chamber. The preheating can be carried out by passing cold air around the outside of the combustion chamber and then using this heated air to preheat the coal in bunkers.  For this purpose the combustion chamber is provided with a hollow casing surround-ing the combustion chamber proper and a partition in the hollow casing pro-vides an annular outer space and a concentric annular inner space.  A helical baffle arrangement is also provided in the inner and outer spaces to guide the cold air down the outer space and up the inner space.  The coal is burned below the melting point of the coal slag and this produces a soft ash rather than molten material.  The ash is cleaner and cannot bake onto burner housing.  Heat is stored in the combustion chamber wall and the time of residence of the coal in the combustion chamber is increased by impart-ing a spiral motion to the coal and/or air supplied to the combustion chamber. The layer residence ensures more complete combustion.

Abstract: Abstract:        Apparatus for use with a pair of thermo-plastic strips of the type illustrated in Abildgaard Laboratories United States Patent No. 3,608,117 dated September 28, 1971 wherein one strip is formed with studs longitudinally spaced at intervals and a second strip apertured and counterbored at the same intervals is used to bind sheets apertured at the same intervals at locations spaced inward from one marginal edge is described.  A pressure bar is first manually moved to operative position and a handle compresses the strips together by exerting a controlled force on the pressure bar.  The handle then initiates movement of a sup-port for a knife consisting of a length of metallic ribbon material having spaced horizontal stretches in horizontal align-ment with excess stud lengths of the first strip projecting through the second strip, the ribbon being under tension to hold such stretches taut.  As the support moves toward the studs a current is passed through the ribbon, heating it so that the ribbon functions to cut off the excess stud length slightly below the second strip.  The current then is terminated as the support moves upward forming heads on the stud stubs filling the counter-bores in the second strip.  By this time, the ribbon has cooled and functions to cool and harden the heads.  Retraction of the handle returns the support to initial position and releases the pressure bar.  The handle also actuates a punch for the apertures in the sheets, the punch being located at a different station in the machine from the binding mechanisms.
