Abstract: Z  257 (R) Abstract of the Invention A moisture-permeable film from thermoplastic material as covering layer for absorbent layers of an article has embossments with openings arranged at their ends. The embossments are formed in such a way that their side walls extend at approximately right angles to the base surface. As a result the embossments form capillaries with a cross-section which does not change  over the entire depth of the embossments. The embossments and the openings can have any shape. Preferred are slit-shaped embossments having dimensions of 0.3 by 2 mm, which have been arranged in rows, staggered and in alternating direction.

Abstract: Abstract The invention provides improved stator windings for pole-amplitude modulation (P.A.M.), pole-changing electric motors and generators, using symmetrical pole-combinations.           In large machines of high pole-numbers, the effect of adjacent harmonics of m.m.f waveform becomes evident in the form of low-frequency vibration of the frame.  In small machines the effect, although present, is less important.           The invention provides stator windings, particularly for large machines, wherein the phase-winding coil grouping, selected primarily for sinusoidal modulation, is selected secondarily to include a third-harmonic modulation content, whereby the adjacent harmonic m.m.f. content is reduced for both alternative pole-numbers.

Abstract: ELECTRO-OPTIC MODULATOR WITH IMPROVED ACOUSTO-OPTIC SUPPRESSION, HEAT TRANSFER AND             MECHANICAL SUPPORT     ABSTRACT OF THE DISCLOSURE    An improved electro-optic modulator device is disclosed which provides strain-free mounting of an electro-optic crystal within a housing assembly and suppression of acousto-optic effects within the crystal.  An acoustic matching liquid having an acoustic impedance substantially matching the acoustic impedance of the electro-optic crystal is disposed within the housing enveloping longitudinally the crystal.  The acoustic matching liquid effectively suppresses the acousto-optic resonances within the crystal by coupling the acoustic energy out of the crystal into the liquid.          The liquid enveloping the crystal also provides a uniform heat conduction path for minimizing thermal gradient variations and the resulting thermally induced strain within the crystal.  A zinc oxide suspension in silicone oil is an exemplary acoustic matching liquid for gallium arsenide or cadmium telluride crystals.  In one embodiment the acoustic matching liquid has a consistency of a slurry capable of being recirculated through the housing to improve the heat transfer characteristics of the liquid.  In a further embodiment an acoustic absorber, disposed in a spaced apart relationship about the crystal, is adapted for absorbing acoustic energy transmitted through the liquid.  An elastomeric seal at each end of the crystal provides a liquid-tight seal between the housing and the crystal to maintain the liquid within the housing and provides a soft-mounting structure to minimize thermally and mechanically induced strain within the crystal.

Abstract: Abstract This invention relates to hot melt adhesives for use in coating and/or laminating paper.  Conventional hot melt adhesives used to manufacture a coated or laminate product with good vapor barrier characteristics are based on ingredients compounded with significantly lower proportions of inert low cost filler materials.  The present invention provides a hot melt adhesive/ coating blend which not only provides a moisture vapor barrier and/or bonding but also significantly reduces the quantity of more expensive ingredients through the use of a large quality of a lower cost ultra fine ground inert inorganic filler material and a low cost modifying hydrocarbon resin.   The blend or composition consists essentially of, in parts by weight, up to about 25 parts of a hi melt point paraffin wax,  10-30 parts of a modifying hydrocarbon resin,  1-20 parts of an elastomeric copolymer, and 20-85 parts of an inert inorganic filler material.   Preferably the blend additionally contains up to about 25 parts of a microcrystalline wax. The material is inexpensive, can be readily reactivated by heating, can be applied as a continuous coating, has excellent non-blocking and MVTR properties, holds the filler material in suspension, is inexpensive, has good polymeric tensile properties, is not tacky when cold, has good cold  cracking  resistance  at  low  temperature  and  may be  readily recycled.

Abstract: DYNAMICALLY VARIABLE PRIORITY, VARIABLE POSITION CHANNELS IN A TDMA BURST     Abstract The position of a channel of information transmitted from a particular port is varied in response to the changing priority of that port's messages as time passes.  Variable priority assignments become necessary when low speed data has been deferred in its trans-mission until a time just prior to the production of a second unit of data. The effect of changing the pri-ority of deferred data messages in a TDMA burst is to change the relative position of the associated channel within the TDMA burst by means of compiling the address of that message in a higher priority threaded list.  The mechanism by which a deferred data message has its priority changed from an initial low value to a subse-quent higher value is by measuring the amount of time remaining for retaining a deferred data message relative to the expected time of arrival of the next data message, the impending arrival of a new message causing the priority of the deferred message to be increased, thereby increasing the probability of its successful transmission.

Abstract: ELECTRONICALLY CONTROLLED FLUID INJECTION SYSTEM          FOR AN INTERNAL COMBUSTION ENGINE     ABSTRACT OF THE DISCLOSURE       A fluid injection system for an internal combustion engine such as a spark-ignition engine in which an injection nozzle injects a finely divided spray of fluid, such as water or a water solution, into the engine in response to a flow of atomizing air.  The nozzle is connected to a fluid supply reservoir and to the outlet line of an air-injection pump that is connected to an electronic control circuit which includes an inductive pick-up coupled to the ignition system of the engine and a pressure responsive sensor that is coupled to the intake manifold.  The electronic circuit thus operates the pump in response to engine speed by virtue of its con-nection to the ignition system through the inductive pick-up and in response to engine load by virtue of its connection to the intake manifold through the pressure responsive sensor. AS a result, the flow of atomizing air to the nozzle and therefore the rate and magnitude of water injection is res-ponsive to engine speed and engine load.

Abstract: ABSTRACT OF THE DISCLOSURE:          A continuous casting machine for billets and blooms has a curved mold which is followed by a curved cooling zone and a straightener.  A dummy bar for the casting machine has a length at least equal to the distance between the mold and the straightener.  The dummy bar has a rigid portion and a flexible portion which are pivotally connected with one another.  The rigid portion, which is curved and has a radius equal to the casting radius, includes a dummy bar head.  The flexible portion is made up essentially of pivotally connected, curved links having radii equal to the casting radius.  The flexible portion is designed such that it can assume radii equal to or less than the casting radius.  Then the dummy bar is in position for casting, the flexible portion assumes the casting radius and the dummy bar conforms to the curvature of the casting machine.          Since the rigid portion of the dummy bar need not be supported in this position, less support structure between the mold and the straightener is required than for a dummy bar which is flexible in its entirety.  When the dummy bar is not in use, it is stored with the flexible portion thereof bent to a radius much smaller than the casting radius.  The dummy bar thus takes up less space in storage than a dummy bar which conforms to the cusvature of the casting machine and is rigid in its entirety.
