Abstract: ABSTRACT OF THE DISCLOSURE   A process and apparatus for fractional desublimation of vapor-phase solids from gas vapor mixtures is provided.  The invention results in desub-limation of solids from gas-vapor mixtures by immediate cooling of the gas-vapor mixture in a gaseous space which is made possible by the collision of opposing high velocity streams of gas-vapor mixture and cooling gas. Fractional desublimation of the solids is attained by adjustment of the temper-ature of the cooled gas-vapour mixture.  The solid to be desublimed is obtained with high yields and purity.  The simplicity of the apparatus and the fact that desublimation does not take place on cooled surfaces allows for low-cost, troublefree operation.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides a denture liner composition for a composite denture based on a phosphonitrilic fluoroelastomer [poly(fluoroalkoxy)phosphazene] curable at atmospheric pressure at temperatures of about 100% or less, conveniently by immersing the packed denture flask in a water bath at the appropriate temperature.  The composition includes trimethacrylate and dimethacrylate cross-linking agents for increasing liner hardness and decreasing water sorption characteristics of the cured liner.  The composition preferably further includes filler materials for increasing the hardness of the liner product.  The composite denture is preferably prepared in a one-step process wherein the liner composition material of a single firmness is cured in situ with the denture base material.  Alternatively, a firm liner material is cured at the periphery of the denture, and a softer liner material cured at the center; this provides a firm elastic liner adjustable by grinding where soft tissues must be displaced, and a soft elastic liner over bony anatomy, where stresses from chewing are most concentrated and soft tissues are thin.  Another possibility lies in curing the soft liner directly to a precured denture as a reline procedure in a pre-existing denture.

Abstract: Abstract Improved Film Cooling Passages With Step Diffuser A film cooling passage through the wall of a hollow airfoil for a gas turbine engine has a metering section communicating with the interior of the airfoil for directing a metered amount of coolant through the passage in a first direction, followed by a mixing section to create turbulence in the flow as it leaves the metering section, followed. by a diffusing section leading to the passage outlet at the outer surface of the airfoil.  The mixing section comprises a sudden jog or step in the flow path of the fluid to suddenly disrupt its forward momentum in the first direction and to create turbulence therein whereby the fluid is more readily able to spread out within the following diffusing section and thereby stay attached to more widely diverging diffusion section walls.  Wider diffusion angles in the coolant passage permits the same amount of coolant to be spread out over a wider area of the surface of the airfoil.

The   circuit  precludes  the  possibility  of   current eminating  from  charged batteries from DC  biasing  the control  coil  and shunt therefor,  when there is no  AC electrical energy being supplied to the circuit  -- such as   during  the  occurrence  of an  AC  power  failure.          Precluding  such DC biasing is accomplished through the use  of a plurality of blocking diodes  located  between the  output  to  the battery and the  control  coil  and shunt.   A  few milliamperes of current are   acceptably permitted  to flow back from the battery to the  sensing and control circuit portion of the charging circuit,  so as to maintain surveillance on the status of the battery and of the circuits;  but no DC current is permitted, in the instance of an AC power outage to flow back from the battery  through  the  control  coil  of  the  input  AC reactor,   due  to  the  presence  of  the  blocking  or isolating diodes.

Abstract: A circuit arrangement is provided for the transmission of digital signals between transmitting and/or receiving stations which operate with differing data transmission procedures and with different data formats. The signal transmission respectively occurs by way of a converter unit which, like the transmitting and receiving installations, is connected to a switching system. In the train of the transmission of digital signals from a transmitting installation operating with a lower data transmission rate to a receiving installation operating with a higher data transmission rate, the digital signals emitted by the appertaining transmitting installation are first collected in the converter unit in order to be emitted to the appertaining receiving installation only given the existence of a sufficient plurality of such signals. The transmission of digital signals from a transmitting installation operating with a higher data transmission rate to a receiving installation operating with a lower transmission rate occurs in data blocks. A respective plurality of data signals forming a block or, respectively, a signal group, is emitted together with a signal group end mark by the appertaining transmitting installation to the converter unit which then relays the digital signals to the appertaining receiving installation. In order to minimize control expense, the converter unit checks its signal acceptance capability upon the occurrence of the group end mark. Only given existence of a sufficient signal acceptance capability in the converter unit is an acknowledgment character emitted to the transmitting installation, the acknowledgment character then causing the transmission of signals forming a further signal group or block. The invention is preferably employed for signal transmission between telex stations and office printergram or teletex stations.
