Abstract: 914,247 ABSTRACT          A composite material for forming graphics such as letters or numbers.  The composite material includes a layer of latent adhesive material, a mono-layer of granules lightly adhered to a donor web, and a thin layer of bonding material between and in face-to-face contact with the layers of granules and adhesive.  The layer of bonding material maintains the adhesive and granular layers in close proximity and excludes air from there-between.  When the composite material is selectively heated in graphic patterns, corresponding portions of the bonding layer melt; and corresponding portions of the ad-hesive material and granular layer soften, absorb the melted portions of the bonding layer and adhere together.          Upon subsequent separation of the layer of adhesive and the donor web the remaining portions of the layer of bonding material separate, whereas granules transfer to the accepting tape in the heated areas to provide the graphics.

Abstract: VISCOUS OIL RECOVERY METHOD      (D#73,500-RCA-14-F) ABSTRACT OF THE DISCLOSURE         Disclosed  is  method  for  treating  a  high permeability communication channel between wells for use in a viscous oil recovery method to stabilize fine particulate matter present in the communication channel to prevent movement of fine particles during the oil recovery process.          The communication channel is formed by fracturing or sweeping with air followed by introducing a viscous oil displacing medium such as  a solvent or  steam to  desaturate the previously fractured or air swept zone in the formation, converting it into a high permeability channel between wells.   In order to stabilize the fine grain sand and other minerals present in the communication channel to prevent migration thereof which results  in loss  of permeability of the communication channel, the channel is treated with a hydroxy aluminum solution and allowed to age for a period of time sufficient to form crystalline aluminum hydroxide which cements the grains together while maintaining permeability of the  communication channel.   Thereafter the primary oil recovery fluid, such as steam, may be injected through the stabilized, high permeability communication channel for long periods of time sufficient to heat the portions of the oil saturated formation above or below the channel, and strip viscous petroleum therefrom, so a substantial amount of the oil present within the pattern being subjected to the oil recovery process may be recovered.     -I-

Abstract: CLOSED LOOP POTENTIAL REGULATED POWER SUPPLY                CIRCUIT ARRANGEMENTS                        Abstract This closed loop potential regulated acidic power supply comprises a power supply transformer having two sets of secondary windings and a compensating trans-former having exciting windings and two compensating windings.  The compensating windings are connected in-dividually in series circuit with the principal power supply secondary windings to which a full wave rectifier circuit and an electric load are connected.  The exciting windings of the compensating supply transformer have ac potential applied thereto from the other secondary windings on the power transformer which also supply dc power by means of another full wave rectifier circuit for compensating control circuitry which has an input circuit connected across the load to sense potential variations thereat and an output for varying the ac supply to the exciting windings inversely of variations in load potential.  A differential amplifying circuit is used for determining the load potential variation.  The error signal produced at the output of the differential amplifier circuit is applied to a transistor effectively to insert a dc component in inverse feedback relationship into the exciting windings of the compensating transformer. As the output potential of the power supply increases, the input potential to the rectifier assembly is decreased, and the converse.  The direct current flow path is com-pleted through the load whereby little or no energy is dissipated elsewhere.

Abstract: TEMPERATURE STABILIZATION SYSTEM           D#76,297-F            ABSTRACT OF THE DISCLOSURE       A radiation detector assembly is enclosed in a heat pipe which is positioned in a dewar flask.  A thermo-electric cooler is joined to one end of the heat pipe.  The heat exhaust of the thermo-electric cooler is communicated to a heat dissipation device in the form of a fin assembly.  A thermistor senses the temperature at the heat pipe.  When the thermistor indicates a temperature in excess of that corresponding to a reference signal, a control singal is produced by a control device to cause a power source to operate the thermo-electric cooler to remove heat from the heat pipe to the fin assembly.          The vacuum within the dewar flask effectively limits the en-vironmental heat passing to the heat pipe to radiant heat.  The detector assembly and temperature stabilization system may extend to the interior of a conduit or other housing containing material whose radiation is to be detected, while the fin assembly is exposed to the atmosphere.  In particular, the temperature stabilization system may be used in conjunction with a detector comprising a scintillation crystal optically coupled to a photomultiplier tube in an environment which would otherwise diminish the performance of such a detector by raising its temperature.
