Abstract: Abstract of the Disclosure Paper products are sized with a sizing emulsion formed in the absence of high shearing forces and under normal pressures and containing 80 - 97 parts of a substituted cyclic dicarboxylic acid anhydride, 3 - 20 parts of a polyoxyalkylene alkyl or polyoxyalkylene alkyl-aryl ether or the corresponding mono- or diester, and water.  The sizing step is accomplished by intimately dispersing the size emulsion within the paper stock prior to its passing through the drying stage of the paper-making operation in an amount which provides a concentration of the substituted cyclic dicarbox-ylic acid anhydride of 0.01 - 2.0%, based on the dry fiber weight.  The improved size properties of the resulting paper product, e.g., resistance to water or acidic ink solutions, are achieved in this method using a smaller amount of size as compared to prior art sizing methods.

Abstract: ROTATIONAL COLLAR ALIGNMENT DEVICE    (Abstract of the Disclosure) A self-contained fluorescent lamp fixture for instal-lation in a conventional incandescent lamp socket which permits selective adjustment of the fluorescent lamp fixture through a substantial arc and which readily facilitates retention of the fixture in the adjusted position.  The new fixture includes a body cover which is adapted to receive a conventional fluores-cent tube as well as the other components required to make the tube operational.  This cover includes a pair of opposed, gen-erally centrally located arcuate slots and is mounted between upper and lower fixture collars by a pair of threaded fasteners.           The fasteners pass between the collars through the arcuate slots whereby the cover may be selectively rotated in a plane normal to the axis of the fixture.  The upper collar includes means for threadedly mounting the entire fluorescent fixture in an incandescent type lamp socket.  A generally flat, compressible member is received between the lower collar and the fixture body cover such that as the upper and lower collar are brought into a closely spaced relationship with each other, the member is com-pressed. This action places a continuous biasing force against the cover urging it toward positive engagement with the upper collar.  The fixture body cover, including the fluorescent tube, may then be rotated for alignment purposes and will be retained in the aligned position by means of the frictional force created by the compressible member urging the body cover toward engage-ment with the upper collar.  The arcuate slots define a generally circular configuration and each extends through an arc of approxi-mately 170° whereby the cover body may be moved through an arc of approximately 170° for alignment purposes

Abstract: ABSTRACT OF THE DISCLOSURE           A catalytic reactor in which feed, catalyst and diluent gas enter the bottom of a reactor which has a cross-sectional area which does not decrease substantially, preferably which has a substantially constant cross-sectional area, from the point at which catalyst and feed first come in contact to the reactor outlet.  Atop the reactor is a disengage-ment vessel of relatively large diameter in which the product gases are separated from the catalyst.  The catalyst drops through a stripper culminating in a bend which collects catalyst to provide a seal between the reactor and a regenerator.  A lift line carries the catalyst to the top of the regenerator through which the catalyst moves downward to a transfer line that returns the catalyst to the reactor. Flue gases are removed from the top of the regenerator. The transfer line culminates in a bend to collect solid catalyst, providing a seal between the regenerator and the reactor. Fluidizing gas is introduced into the transfer line by an inlet probe which can be moved vertically so that the level within the transfer line at which the gas is introduced can be varied to control the catalyst flow rate.          An improved process of catalytic hydrocarbon conver-sion has also been discovered.

Abstract: VARIABLE CYCLE GAS TURBINE ENGINES                 Abstract of the Disclosure A design technique, method, and apparatus for varying the bypass ratio and modulating the flow of a gas turbine engine of the bypass type in order to achieve improved mixed mission performance. The disclosed preferred embodiments each in-clude a gas flow control system for management of core and bypass stream pressure comprising diverter valve means down-stream of the core engine to selectively mix or separate the core and bypass exhaust streams. The flow control system may also include variable geometry means for maintaining the engine inlet airflow at a matched design level at all flight velocities. Each preferred embodiment thus may be converted from a high specific thrust mixed flow cycle at supersonic velocities to a lower specific thrust separated flow turbofan system at subsonic velocities with a high degree of flow variability in each mode of operation, wherein the engine inlet airflow may be maintained at a matched design level at all engine velocities. To further improve flow flexibility and assist in maintaining the engine inlet airflow matched to a design level throughout a variable velocity range, the flow control system may include a split fan in conjunction with two concentric bypass ducts, The disclosed variable cycle engine techniques, methods, and apparatus result in significantly reduced inlet and after-body drag levels and result in significantly improved installed fuel consumption for mixed mission aircraft.

Abstract: SELF-CHECKING READ AND WRITE CIRCUIT     Abstract of the Disclosure A self-checking read and write circuit interfaces a control circuit with a plurality of peripheral circuits.          The read and write circuit receives address and data commands from the control circuit, decodes the commands and produces a driving signal to operate relays in the peripheral circuits.  The read and write circuit also receives inputs from the peripheral circuits indicating the state thereof, multiplexes the inputs and forwards them to the control circuit under control of address signals.  The circuit is self-checking in that a readout multiplaxor which scans for state changes in the peripheral circuits has its even parity inputs connected at the outputs of the drive signal decoder and its odd parity inputs connected to the scanned points.  A parity check circuit on the multiplexor address leads determines whether the address has even or odd parity.  If the parity is even, the output of the multiplexor is compared to the data input of the drive signal decoder.  If the parity on the address leads is odd, the output of the multiplexor is forwarded to the control circuit.  A single hardware failure in the multiplexor address circuitry causes a failure in one of several modes involving a shift in parity values.  These failure modes are detected when the output of the multiplexor is compared to the data input of the drive signal decoder.
