Abstract: IMPACT MODIFIED HIGH MELT FLOW POLYCARBONAMIDE     Abstract 77-11                    Disclosed is a method for preparing an impact-resistant, high melt flow polycarbonamide comprising the steps of:          (a) preparing an impact modifier concentrate comprising a mixture of (i) 70-90 parts by weight of an acrylic impact modifier and (ii) 10-30 parts by weight of at least one high molecular weight aliphatic polycarbonamide; and (b)  mixing 10-30 parts by weight of the impact modifier concentrate from (a) above with 70-90 parts by weight of at least one low molecular weight aliphatic polycarbonamide. The resulting polycarbonamide blends are characterized by high impact resistance and a melt flow which is essentially the same as that of the blend of the acrylic impact modifier and the low molecular weight nylon alone.

Abstract: ABSTRACT           Solid sulfur pellets are made by dropping sulfur parti-cles in two distinct curtains of particles within a drum having a tumbling bed of such particles.  The larger curtain of particles is sprayed with molten sulfur and the smaller is sprayed with water above the bed.  This indirect appli-cation of water keeps the temperature of the bed as well as the other curtain of particles being sprayed with sulfur within predetermined temperature ranges which produce high quality sulfur pellets.  Dust emissions are prevented by classifying as to size a third falling curtain of recycled particles and spraying molten sulfur on the side containing dust particles.  Seed nuclei are produced by intermittantly raising the temperature of the tumbling particle bed about 40°F for short periods of time.

Abstract: ABSTRACT OF THE DISCLOSURE The specification discloses a forming die movable along a track by a pair of toggle-joint linkages to move from a column of staples a staple hav-ing a downwardly bowed central portion into engagement with an anvil, then bend outer portions down over the anvil to drive pointed legs into the flesh and bring the legs into alignment with each other.  The column of staples is pressed by a spring arm and a follower toward the track and is laterally sup-ported in a staple magazine.  Each toggle joint-linkage is a one-piece member with two rigid arms connected by an undulating spring portion.  The magazine is detachably connected to the track by spring latches.  Another stapler has a hook-like anvil, and the bowed central portion of the staple as it is pres-sed against the anvil by a forming die or ram, is first straightened and then bent legs are bent from the central portion, thus giving a "soft" initial feel to the stapling.

The gear boxes 41, 41' are driven by a cross-shaft 48 from a tractor p-t-o.  The drums are driven by untimed drive and clash of cutting knives 31, 31' is prevented by a spacing roller 102 which rolls over a cam plate 102' and forces the drums 29, 29' apart when the drums are cutting at the same level.  Support members 9 and 9' move apart on cross members 21, 21' and are linked together by tie bar 103 to give overlap of cutters when cutting at different levels.

Abstract: A BLOCKING MACHINE                   Abstract of the Disclosure Loose hay or the like is delivered into a progressively narrowing axial space between two rows of identical teeth which project towards each other from side locations on a pair of obliquely related wheels.  The hay or other material is simulta-neously compressed and advanced by the teeth as they come together.          The teeth form axial boundaries for pockets or chambers in which the hay or other material is compressed into blocks.  The radial boundaries of such pockets or chambers are formed by an annular outer wall carried by one of the wheels and an annular inner wall carried by the other wheel.  One of the wheels is mounted for rotation in a fixed position.  The other wheel is mounted for rotation by mounting means which can be shifted in position for the purpose of varying the axial space between the two wheels, for adjustment of the pocket size.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for cutting pattern pieces from sheet material with an automatically controlled cutting machine utilizes special control techniques for guiding a reciprocating cutting blade accurately along a desired cutting path defined by the pattern piece peripheries.  The cutting machine includes a control computer which also serves as a data processor for generating machine command signals and controlling cutting blade movements.  The controller has memory units which contain standard cutting programs and optional programs.  From a program selector panel, the cutting machine operator can select optional programs which modify the standard programs in a manner most suitably adapted to cause the cutting blade to follow the cutting path in the sheet material more accurately.  The optional programs vary the feed rate or stroking speed, introduce yaw signals to control blade orientation along the cutting path, or perform other control functions.

Abstract: ABSTRACT OF THE DISCLOSURE          An abnormal tire profile indicating system comprising a telemetry unit mounted on each wheel of a vehicle and a central receiver.  Each telemetry unit comprises a piezoelectric transducer which is deflected with each wheel revolution when the tire profile is low. Deflecting the transducer produces an electric pulse.  The transducer pulses are accumulated on a charge storage capacitor until a threshold level is reached.  A threshold level detector causes a transistor connected to the capacitor to become conductive when the threshold level is exceded.  This transistor, when conductive, powers a counter, an encoder and a transmitter.  The counter counts the number of times the transistor become conductive and produces an enable signal when a predetermined number is counted.  The enable signal enables the transmitter to receive an encoded signal from the encoder and modulates a radio carrier frequency with the encoder signal.  The modulated radio signals are received from each telemetry unit by the central receiver.  The central receiver produces an indicia of the occurrence of the abnormal tire profile at one or more of the wheels.  The counter limits the transmitter to transmitting only after a sufficient number of detections to assure that the sensed conditions are due to a low profile rather than rough roads or extraneous signals.  Further, the counter allows radio transmissions only after a sufficient number of wheel revolutions to meet FCC requirements on the periodicity of transmissions.
