Abstract: ENERGY-EFFICIENT EVAPORATION PROCESS WITH        MEANS FOR VAPOR RECOVERY            Abstract of the Disclosure A process is disclosed for the recovery and reuse of heat contained in the wet exhaust gases emanating from a solids dryer or liquor concentrator, particularly one in which drying or concentration is facilitated by purging the vapor with some noncondensable gas such as air or nitrogen.  Water or solvent vapor in the moist exhaust mixture is separated from the noncondensable gas or gases by preferentially passing the vapor through a semiper-meable membrane.  The water or solvent vapor is then com-pressed and subsequently condensed in a heat exchanger, permitting recovery of its latent heat of vaporization for reuse in the evaporation process.  In a drying process, this recovered energy is conveniently used to reheat the dry gases that exit from the membrane separator, per-mitting the hot, dry gases to be recirculated through the dryer.  Alternatively, an indirect heat exchanger may be used to transfer this heat to the material being dried.          In an evaporative process for the concentration of a liquor, the recovered energy may be used either to preheat the dry purge gases or to heat the dilute liquor being concentrated.

The inter-mediate diurethane is separated from starting materials and by-products and thermally cleaved to alcohol and diisocya-nate which are separated by fractional condensation of the products from the vapor state.  This process gives high yields of the desired diisocyanate and lends itself particu-larly to continuous processing.

Abstract: BREAKWATER MODULE AND MEANS FOR PROTECTING A SHORELINE THEREWITH                Abstract of the Disclosure A concrete breakwater module for use with like modules positioned side-by-side in a line along or offshore from a beach or bluff for preventing erosion due to wave action and for reversing previous erosion.  Each module has a single, large, upwardly concave, wave-energy-absorbing trough of partly cylindrical and partly flat-bottomed contour adjacent rear and front upright walls respectively located at opposite ends of a bottom, base wall.  The front wall has a sloping front end surface directing incoming waves and spray over the trough.  The rear wall is substantially higher than the front wall to intercept waves and spray and re-direct them downwardly along a cylindrical surface and forwardly in the trough providing a rolling and swirling action of water which erupts at the front wall in a countercurrent manner against waves and spray overtopping the front wall.  In one embodiment, one or more horizontal passageways extend through the rear wall, and have forwardly diminishing areas, to direct jet-like streams forwardly into the trough when water level on the shore side is relatively high.  These streams augment the rolling action of water in the trough and enhance wave energy absorption.  Sediment precipitates out of water when it flows rearwardly through these passageways.  Embodiments are illustrated forming single and double breakwaters to protect a beach, along a sea wall to protect it from undermining, and along the toe of a bluff to protect it from slumping.

Abstract: ABSTRACT          Disclosed is an electromagnetic shielded door seal which will block both low frequency electromagnetic waves as well as very high frequency electromagnetic waves.  The sealing effectiveness of the door seal which may be used for a shielded enclosure, is improved by introducing a high frequency impedance between the two coacting surfaces of the door seal.  The door seal is provided with two cooperating members which move relative to one another.  At least one of the members contains a small cavity therein which is filled with a dielectric or lossy material.  The periphery surrounding the cavity is closed, with the exception of a small gap ensuring communication between the material provided within the cavity and a sealing surface between the two cooperating members.  The combination of this gap and the dielectric material introduces a high frequency impedance between the surfaces of the seal.  This impedance results in a voltage dividing action and reduces the voltage across the protected surface of the door seal.

Abstract: ABSTRACT           A sample and hold circuit contains a pair of dif-ferential amplifiers (A1 and A2) switchably arranged in series.  The circuit input signal (VIN) during sample is provided to the first amplifier (A1) which is coupled to a storage capacitor (C).  The second amplifier (A2) pro-vides the circuit output signal (VOLT) during hold.  Switch-ing circuitry (S1, S2 and S3) enables the input and output signals to undergo the same transfer function in the first amplifier.  The voltage offset of the first amplifier is thereby cancelled out of the output signal, while the effect of the voltage offset of the second amplifier is reduced drastically so as to provide excellent auto-zeroing.

Abstract: Abstract of the Disclosure Microencapsulated materials are released by rupturing of an adhesive layer on a substrate containing the capsules.  The novel article comprises two sheets or opposed faces of a folded single sheet which are temporarily bonded by means of an adhesive with rupturable microcapsules dispersed therein and on the exterior surface of one or said sheets is an adhesive layer.  The microcapsules are ruptured by pulling apart the sheets after they are first adhered to another surface which causes the capsules to rupture and release the ingredients contained therein.  By selecting the relative physical properties of the sheet, adhesive, capsules and the binding forces amongst them, a high rate of capsule rupturing can be obtained consistently. The materials may be used, for example, in pull-apart fragrance-releasing sheets.
