Abstract: DIGITALLY ENCODED TOP OCTAVE    FREQUENCY GENERATOR     Abstract of the Disclosure A LSI (large scale integrated circuit) device is disclosed which generates twelve output frequencies related to each other by a multiple of the twelfth root of two from a common time base without the use of parallel divider or shift register strings.  The output frequencies comprise the top octave, or a multiple thereof, of the frequencies of an electronic musical instrument,  A binary counter serves as a common time base and encodes each wave form period in a form of a binary code.  A binary processing circuit associated with each output frequency stores the count position of the next desired wave form transition and updates the stored code after each transition has occurred,  The binary processing circuitry comprises a latch circuit, a binary full adder or ROM (read only memory), a digital comparator or ROM, and a J-K flip-flop circuit,  The outputs can be easily modified in both actual frequency and waveform symmetry.

Abstract: FLOW CONTROL VALVE FOR COMBINING TWO DISSIMILAR INDEPENDENT SYSTEMS TO A COMMON PRESSURE SOURCE     A B S T R A C T     The invention is concerned with an improvement in a hydraulic fluid system of a vehicle which comprises a variable displacement pump; a first work element; and a device for receiving a first load signal from the first work element and controlling the pump discharge responsive thereto.  The improvement includes a plurality of second work elements which receive fluid flow from the pump via a common supply line connected to the first work element, said fluid flow not passing via any independent load responsive delivery system, and a load responsive controller having flow restricing means in a signal line which communicates with the common supply line for sensing a load pressure in the common supply line, said load pressure being a maximum load pressure of any of the second work elements and delivering a second load signal representative of the load pressure to combine with the first load signal to control the discharge of the pump to be responsive to the larger of the first and second load signals.

Abstract: ABSTRACT OF THE DISCLOSURE A fuel injection pump including a charge pump for delivering discrete pulses of high pressure liquid fuel se-quentially to the several cylinders of an associated engine is provided with an angularly adjustable cam ring to control the timing of the pumping strokes.  The position of the cam ring is controlled by an advance piston, the position of which is controlled by a hydraulic pressure correlates with engine speed.  A load sensing piston, engageable with one end of the advance piston above a fixed amount of timing advance, is subjected to the pressure of the metered fuel downstream of the metering valve which controls the quantity of fuel delivered by the pump to urge the advance piston in a direction to retard the timing of the pumping strokes to result in a timing control system in which the timing is more advanced at high speeds and light load than it is at high speeds and full load.

Abstract: SURGICAL APPARATUS FOR SIMULTANEOUS RESECTION OF SOFT   TISSUES AND THEIR SUTURING WITH METAL STAPLES              Abstract of the Disclosure A surgical apparatus for the simultaneous resection of soft tissues and their suturing with metal staples comprises an anvil and a staple branches, hinge-connected and having longitudinal jaws situated one opposite the other. A longi-tudinal row of grooves is made on the jaw of the anvil branch for clinching the ends of staples, while slots for the staples with staple tappets placed therein are provided on the jaw of the staple branch opposite said grooves. A plank with a wedge bevel on its end intended for interaction with the staple tappets when ejecting the staples is situated in the slot of the staple branch, and is longitudinally movable therealong. Rotation shafts are set along each branch with needles set perpendicularly to them, intended for grasping the soft tissue. Rigidly secured on the shafts are cranks, movably connected through a link so that when the branches are being drawn together, this provides for the rotation of the shafts with the needles towards each other, resulting in the portion of the soft tissue, grasped by the needles, being forced into the clearance between the branches with the formation of a roll of soft tissue intended for excision. Situated on the staple branch is a blade for excising said roll of soft tissue, longitudinally movable together with the plank actuating the staple tappets.      The apparatus makes it possible to separate a blood-supplied graft of soft tissue or remove an area of soft tissue with the simultaneous suturing of the wound there beneath, providing for minimum loss of blood and reducing the time of the operation.

Abstract: ABSTRACT     Lignocellulosic materials, e.g., wood, bagasse, straw, reeds, and other plants and crops can be de-lignified effectively by soda-type pulping with an alkaline liquor containing small quantities of both ethylenediamine or like diamine compound, and a cyclic keto compound, e.g., anthraquinone or 2-methyl-anthra-quinone.  The diamine is not effective, in the absence of the quinone significantly to affect pulping rate, yield or physical strength properties of the pulp. Nevertheless, in the presence of the cyclic keto com-pound, the diamine either reduces the amount of cyclic keto compound required to achieve the desired pulping rate and the yield, or improves the physical strength properties of the delignified pulp to kraft-like values.  Pulping rates comparable to kraft are achieved and the pulps thereby obtained have excellent physical properties, especially tear strength.

Abstract: SPIKED LOW-VOLTAGE AGING OF CATHODE-RAY TUBES       ABSTRACT         During low voltage aging of a completely assembled cathode-ray tube, at least three voltage spikes at least three minutes apart are applied to the heater.  Each spike has a voltage peak higher than the constant voltage applied to the heater during low voltage aging, and lasts for up to 120 seconds.  This results in higher average emission levels and a reduced tendency of the emission levels to slump during emission testing of cathodes so processed.
