Abstract: NOTCH FILTER NETWORK An electrical filter network with improved characteristics is disclosed for selectively attenuating and passing two different, closely spaced frequencies.  The notch filter network includes a low Q reactive circuit tuned to be parallel resonant at the frequency to be attenuated.  A cavity resonator with a high Q is inductively coupled to the reactive circuit and is tuned to be resonant at the frequency to be passed.  Utilizing these concepts, a multicoupler may be constructed to consist of two or more such filter networks in combination with a transmission line. In such a multicoupler, the network adjacent to the antenna terminal is separated therefrom by a multiple of a half wavelength. Additional filter networks are separated from one another by an odd number of a quarter wavelength.  With this arrangement, each network passes a band around the frequency to which the high Q cavity is tuned and rejects a band of frequencies around the reactive circuit resonant frequency.

Abstract: ABSTRACT OF THE DISCLOSURE      An initial input list in a series of sequential dependent input lists is clocked through a first sort stack and written in to a first buffer as Q groups of P numbers each.  The P numbers are in numerical order within each group with the smallest number in the first location of each group.  The first number in each group is loaded into a second sort stack which arranges them in numerical order, causing the smallest number in the imput list to form the first number in the initial output list.  A replacement number is numerically sorted into the second stack from the Q groups each time the smallest remaining number is clocked out.  Each replacement number is from the next location of the same Q group as the most recently clocked out number. Thus, the smallest remaining number in any of the Q groups of the first buffer is always available to the second stack and appears as the smallest remaining number in the second stack is always in the first location of the second stack. As the contents of the first buffer are inserted in to the second stack, the first sort stack processes a next input list into a second buffer.  The buffers read and write in overlap manner permitting both sort stacks to precess input lists simul-taneously.  As each smallest remaining number of the initial list becomes available at the output of the second stack, it may be updated and returned to the input of the first stack as an element of the subsequent dependent list.  The double buffer overlap op--eration approximately doubles the throughput rate and permits updating of the dependent lists.

Abstract: A process for making a high molecular weight polyamide, wherein a diacid-rich component and a diamine-rich component are prepared separately in nonstoichio-metric proportions, each of these components melting below the melting temperature of the polyamide product, and preferably below 200°C; and then the diacid-rich component and the diamine-rich component are contacted in liquid state at high enough temperature to prevent solidification, and in proportions such that the total amounts of diacid and diamine, whether combined or not, are as much as possible stoichiometric. A major utility of this process is in the production of Nylon 66, a known fiber-forming polyamide and engineering plastic.

Abstract: Case 770510 MOBILE ANTENNA WITH ADJUSTABLE      RADIATING ELEMENT                   James P. Liautaud Abstract of the Disclosure A mobile antenna includes a radiating element which can be adjusted to an effective length to tune the antenna to a desired operating frequency without changing the physical length of the element.  The radiating element is slidably received in a sleeve member positioned within a central bore having a tapered end of progressively de-creasing diameter within the antenna base.  The radiating element is locked in position by a deformable rim portion of increased diameter on the sleeve which is drawn into the tapered end of the bore and clamped around the radiating element by means of an axially-aligned bolt threaded into the opposite end of the sleeve.  The bolt is preferably accessible only when the antenna is removed from its mounting base to discourage tampering with the antenna.

Abstract: ABSTRACT        An integrated logic circuit having a signal input which is formed by a base of a bipolar transistor and having a plurality of signal outputs which are each coupled, via a diode. to the collector of the bipolar transistor.  This bipolar transistor has additional means by which an effective complementary auxiliary transistor is incorporated which dissipates a considerable part of the base current in the case the bipolar transistor is overdriven.  The storage of mobile change carriers in the overdriven bipolar transistor can be considerably restricted and controlled and this avoids the need for a Schottky clamp diode across the base-collector junction of the bipolar transistor.

Abstract: Desensitizing Helicopter Control Response To Inadvertent Pilot Inputs Abstract A helicopter having an automatic flight control system including an inner, stability loop is rendered less sensitive to short-term, inadvertent pilot inputs by applying a washed-out derivative of a stick posi-tion signal to the inner stability loop in a sense to countermand the pilot action.  Using a washed-out signal countermands only short-term rapid stick motions, which may be induced by the pilot actively, but in-advertently, or inactively due to coupling between the pilot or the stick and motion of the fuselage, while permitting purposeful, long-term stick positions to have the full, intended effect.

Abstract: ABSTRACT           "IMPROVEMENTS IN OR RELATING TO TEXTILE FABRIC BELTING"     A problem encountered in increasing the tensile strength of conveyor belting is that when the belting is made thicker to increase its strength, it becomes difficult to impregnate the interior of the belting carcass.   To overcome this difficulty, the invention provides a method for manufacturing solid woven beltings which comprises weaving a textile fabric carcass having a plurality of integrally woven layers of weft and subsequently impregnating and coating said carcass with a polymeric material, the textile carcass having five or seven integrally woven layers of weft and being woven in such a manner that the warp yarns define a plurality of continuous flow paths along which the impregnant can travel from the outer surfaces of the carcass to the interior core and each of the warp yarns defines such a path.   The weft layers may be interlocked solely by dual function warp yarns all of which serve simultaneously to impart tension resistant strength to the fabric.
