Abstract: ABSTRACT OF THE DISCLOSURE           A reversible lock washer in combination with a threaded fastener which has at least one cam surface.  The lock washer has an annular washer body with an outer peripheral ring portion and an inner peripheral ring portion, with the inner ring portion de-fining a central opening in the washer body.  The washer body is formed having oppositely positioned engaging surfaces, with each engaging surface including an inner annular recess with the width of each recess being less than the total width of the washer body to define the inner and outer ring portions.  Cam means are formed on opposite sides of the inner ring member for matching engagement with the cam surface on the fastener.  The cam means on the washer consist of a plurality of contiguously arranged cam members formed on the opposite sides of the inner ring portion and are disposed in the recesses with the height of the cam members being equal to or less than the depth of the recesses.  The fastener consists of a screw having the cam surface formed thereon and positioned to en-gage the cam members of the washer body, the latter cam members being arranged in a counterclockwise direction when faced to engage the cam surface of the screw. Frictional means are provided on opposite sides of the outer ring portion, whereby an axial force applied to the fastener is transmitted from the inner ring portion to the outer ring portion, thereby establishing an out-wardly extended moment arm.

Abstract: ABSTRACT OF THE DISCLOSURE     A work-hardenable austenitic manganese steel has a base composition (each in percent by weight) of 0.8 to 1.8 carbon, 6.0 to 18.0 manganese, 0 to 3.0 chromium, 0 to 2.0 nickel, 0 to 2.5 molybdenum and 0 to 1 silicon. The ratio of carbon to manganese is in the range of 1 : 8 to 1 : 14, the remainder being iron, impurities, deoxidation additions and micro-alloying elements.  The micro-alloying elements employed are vanadium and titanium, the total amount of the vanadium and titanium content being limited to the range of 0.05 to 0.08 percent by weight.  The contents of vanadium and titanium should preferably be at least 0.01 percent by weight each, and more preferably at least 0.02 percent by weight each.  The inclusion of vanadium and titanium brings about a reduction in grain size over the entire cross section of even large castings of work-hardenable austenitic manganese steel without impairing their mechanical properties, particularly their toughness.  The steel is cold workable, and is work-hardenable by cold working.  The deoxidation additions consist mainly of aluminum, and aluminum content of 0.02 to 0,09 percent by weight should remain in the steel after deoxidation.

Abstract: ABSTRACT OF THE DISCLOSURE     Successive fly strips are continuously sewn to a continuous slide fastener chain by a continuously operating sewing machine as the fly strips are supplied one after another to the sewing machine.  During this supplying, a succeeding fly strip is superimposed over a preceding fly strip in a feed station while the preceding fly strip is supplied to the sewing machine and is sewn to the fastener chain.  The succeeding fly strip is kept waiting by a stop in its superimposed position for supply to the sewing machine.  When the trailing end of the preceding fly strip is advanced by the sewing machine from the trailing end of the succeeding fly strip as the sewing of the preceding fly strip progresses, the succeeding fly strip is supplied to the sewing station at a speed higher than the rate at which the sewing of the preceding fly strip progresses.  The succeeding fly strip's trailing end catches up with the preceding fly strip's trailing end by the time the latter arrives at the sewing station, contiguous abutting end fashion.

Abstract: A PROCESS FOR THE PRODUCTION OF POLYETHERESTER    POLYOLS AND THE PRODUCTS AND USE THEREOF        ABSTRACT OF THE DISCLOSURE The invention provides a process for the production of polyetherester polyols which have hydroxy-ester groups terminally bound via ester groups to high molecular weight polyether polyol segments.  These are produced by first reacting high molecular weight poly-oxyalkylene ether polyols with molecular weights of from about 400 to 10,000 with an excess of dicarboxylic acids, dicarboxylic acid anhydrides or dicarboxylic acid esters, and then reacting the intermediate product in a further stage with an excess of diols, based on carboxyl groups.         The new, high molecular weight polyetherester polyols thus consist of polyoxyalkylene ether segments, which have terminal ester segments in each case with terminal hydroxyl groups per end group.         Moreover, the use is claimed of the high molecular weight polyetherester polyols as polyhydroxyl compounds for forming polyurethanes.

Abstract: INTEGRATED POWER DRIVE AND POWER          TRANSFER SYSTEM                        Abstract In many aircraft, there are flight control surfaces positioned by mechanical actuation systems that are driven by hydraulic power drive units.  There are also devices for transmitting hydraulic power from one aircraft hydraulic system to another in the event that one of the system's pumps fails.  An integration of structure to perform both of these functions in a single unit would result in a reduction in cost and weight as well as increased reliability.         The integrated power drive and power transfer system has a pair of variable displacement hydraulic devices each in a separate hydraulic circuit and each having a drive shaft connected into a summing gear train connected to an output shaft.  A selectively-operable brake is in the operative connection between the output shaft and the summing gear train and controls either driving of the output shaft with both variable displace-ment hydraulic devices operating as motors or transfer of power between the hydraulic circuits with one variable displacement hydraulic device operating as a motor and the other as a pump.

Abstract: RANDOM ARTIFICIALLY PERTURBED LIQUID JET          APPLICATOR APPARATUS AND METHOD            ABSTRACT OF THE DISCLOSURE          Randomly generated artificial perturbation signals are acoustically coupled to fluid jets to artificially stimulate droplet formation at a rate which varies.  Such changes minimize the discernible effects of anomalies in droplet formation (e.g. along the cross-machine dimension of an extended orifice array) caused by standing acoustic waves or other phenomena.  A relatively low frequency bandwidth-limited square wave with randomly occurring transitions has a controlled amplitude related to a desired magnitude of deviation in the rate of droplet stimulation.  This first random signal is used, in the exemplary embodiment, to control the frequency of a frequency modulated oscillator having a relatively higher mean frequency related to the naturally expected rate of droplet formation.  As a result, piezoelectric crystal drive furnished by the oscillator randomly varies between upper and lower frequency limits.  Provision is also made to ensure that such transition between upper and lower frequency limits is accomplished in a controlled and relatively gradual manner.
