Abstract: ACCELERATION CONTROL SYSTEM FOR HIGH SPEED PRINTER            Abstract of the Disclosure An all-electronic print rate control system for a high-speed column sequential dot matrix printer, using a permutation code input signal, an input storage register with a capacity of at least three code words, for storing the input data and a print timing oscillator.  The control system comprises a print clock, including a plurality of countdown circuits connected to the oscillator, for generating a normal print rate timing signal and a fast print rate timing signal; the print clock can also generate a variable print rate timing signal in which the initial column intervals are longer than in the normal print rate timing signal and the concluding column intervals are preferably shorter than in the normal signal.  A print clock control selects one of these print rate timing signals to control the printing speed in each print cycle, depending on printer conditions in the prior cycle; the variable signal is used whenever the printer has actually come to rest for any appreciable interval.

Abstract: APPARATUS AND METHOD OF FELLING AND          BUNCHING TREES                   Alva Z. Albright, Inventor ABSTRACT OF THE INVENTION Upper and lower parts of an upright structure are horizontally ar-ticulated, and the structure pivoted to a power train below the point of articulation. The axes of pivot and articulation are para-llel, the upright structure being pivotable as a whole and in part past the vertical both forwardly and rearwardly with respect to the power train. The upper part comprises a tree trunk gripper lon gitudinally spaced from and between a pair of trunk stabilizers, and the lower part comprises a stump gripper spaced below a chain saw and sheath which are pivoted to initially engage the forward part of a tree and cut rearwardly, the cut being opened by pivot-ing the upper part rearwardly around the  axis of articulation. All relatively movable parts are actuated by hydraulic apparatus mounted on the upright structure and connected to an auxiliary hydraulic power system of the power train. Bunching is accomplish-ed by releasing the stump gripper from the stump of the severed tree, proceeding to a bunching area, pivoting the severed tree to a horizontal position thereover and releasing it from the trunk gripper. An hydraulic metering device triggered by a relative move-ment between the chain saw and its sheath permits a rapid initial engaging swing of both to be slowed to a cutting swing of the saw. The same relative movement tightens a spring connected therebe-tween for returning the chain saw to its sheath.

Abstract: ABSTRACT OF THE DISCLOSURE    A fuel flow control device is adapted to be used in the place of the conventional pilot jet of the carburetor of an internal combustion engine.  This device comprises a chamber defining first and second valve seats, as well as a double-acting movable valve member cooperating alternatively with said valve seats. The chamber is connected by the first valve seat to a fuel inlet, and by the second valve seat to an air inlet, and its wall has openings by means of which said chamber may be interposed in a low-pressure conduit connected to the carburetor.  Means are provided for maintaining the valve head in an intermediate position, i.e. out of engagement with said first and second valve seats, when the engine runs at idling speed, and for moving the valve head into engagement with the first valve seat when the engine runs at an increased speed, while moving the valve head into engagement with the second valve seat when the engine runs at a very low speed, whereby the fuel flow controlled by the device is interrupted each time the engine runs at a speed different from the idling speed.

Abstract: ABSTRACT OF THE DISCLOSURE    In order to carry out communications among the subsystems of a multiple-bus data processing system without the necessity for providing destination decoding means capable of handling the full addresses of the maximum possible configuration, the destination decoder associated with each message originating Subsystem is provided with the capability for addressing only the ports on its immediate bus.  If a destination code from the originating subsystem indicates that the destination subsystem is located on another bus, a comparator senses this condition and manipulates the lower order field of the destination code to steer the message to a port reserved for direct communication with the specified remote bus.  The entire original destination code is also transmitted to the remote bus for checking for proper bus destination and for directing the message to the designated destination subsystem on the remote bus.  The corres-ponding method for achieving the communication link in the multiple-bus data processing system is inherent in the logic of the apparatus.

Abstract: Abstract of the Disclosure A method and an apparatus is disclosed for measuring weighing and/or mass of an object.  The object to be measured iis subjected to an input frequency signal supplied to a piezoelectric crystal.  Another piezoelectric crystal supporting the object is caused to vibrate in response to the input frequency signal and the mass and/or weight of the supported object.  This second vibrating piezoelectric crystal will then produce a frequency output signal, whose amplitude is a function of the mass (and/or weight) of the object being measured.  The frequency of the input and the output signals are substantially the same.

Abstract: ABSTRACT OF THE DISCLOSURE A catalytic reaction apparatus, such as for steam reforming a hydrocarbon feedstock to produce hydrogen, includes a tubular reactor disposed within a furnace. The reactor includes an annular reaction chamber which is heated along its outer wall by a countercurrent flow of furnace gases traveling through a narrow annulus external thereof.  The reaction chamber is also heated along its inner wall by regenerative heat from the reaction products which leave the annular chamber and flow countercurrent to the flow within the reaction chamber through a narrow annulus disposed along the inner wall thereof.  This apparatus is capable of high reactor thermal efficiency over a wide range of heating rates, including very high heating rates.  The apparatus is very compact and is particularly suited for use with a large number of tubular reactors disposed within a single furnace.
