Abstract: COMBUSTOR LINER                ABSTRACT OF THE DISCLOSURE           A combustor liner for use between a cooling fluid and hot combustion gases is disclosed.  The combustor liner includes portions having different thermal coefficients of expansion so that portions subject to relatively high temperatures have relatively low coefficients of expansion and portions subject to relatively low temperatures have relatively high coefficients of expansion.  In this manner, differential thermal expansion is reduced, thereby reducing thermally induced stresses and distortions.

Abstract: SINGLE BEAM COLOR CRT          Abstract The target of a CRT comprises a substrate on which are formed a plurality of color stripe triads.  Each stripe triad has three epitaxial layers in a staircase geometry and is overlayed with a metal stripe.  The metal stripes are the fingers of a pair of interdigitated electrodes.  A single e-beam scans the stripes horizontally, and a sequence of current pulses generated in the electrodes precisely defines the horizontal position of the beam relative to the triads.  This information is used to precisely time the beam modulation for introducing color signals.  An advantage is the extreme simplicity of the system in comparison with prior art systems.

Abstract: ABSTRACT OF THE DISCLOSURE         The known nuclear hydroxylation of substituted phenols or phenol ethers with organic solutions of hydrogen peroxide in the presence of a catalyst is carried out with special, practically anhydrous solutions of hydrogen peroxide in solvents forming azeotropes with water, said azeotropes having a boiling point below that of hydrogen peroxide, and also with sulphur dioxide as the catalyst.  Therefore, the nuclear hydroxylation can be carried out in a much simpler manner than heretofore.  Water phenol separations are dispensed with and a recovery of the catalyst also is avoidable.  Furthermore, the yields are increased.

Abstract: Chair Tilt Mechanism Abstract A chair tilt mechanism (100) includes a support casting (110) mounted to a chair spindle (104) and a seat casting (130) having a chair seat (102) mounted thereon.  A pair of elongated forward links (150) and a pair of triangular shaped rear links (160) are pivotably connected to both the seat casting (130) and support casting (110).  A slidably mounted spring yoke (210) includes a front vertical portion (212) interconnected between rearwardly extending arms (214) which are pivot-ably connected to the rear links (160).  As the seat casting (130) is tilted, the links (160) pivot away from an initially biased position and the spring yoke (210) compresses a coiled outer spring (200).  A concentric coiled inner spring (202) is provided to increase the spring rate in the event that the outer spring (200) is compressed a certain degree.  In a second embodiment, the springs are compressed by the movement of the front links rather than the rear links.

Abstract: MICROCOMPUTER SYSTEM WITH BUS CONTROL MEANS         FOR PERIPHERAL PROCESSING DEVICES     Abstract A microcomputer system includes a main processor, a memory and a direct memory access controller (DMA) effective to control direct data transfer between the memory and input/output devices on channels.  Bus control for data transfer is switch-able between the DMA and processor by a hold request/acknowledge handshaking sequence between the DMA and processor.  A control line from the channels is activated by a peripheral processing device on a channel when it wishes to gain control of the busses for data transfer.  Logic means coact with the handshaking sequence to determine which device gains control of the busses.  This logic is responsive to the DMA address enable output (AEN), the hold acknowledge output of the main processor (HLDA) and the channel control line output (-MASTER). When all these are deactivated, control passes to the main processor, when AEN and HLDA only are activated, control passes to the DMA controller and, when all three are activated, control passes to the peripheral processing device.

Abstract: Abstract A  mixture  of  sulfuric  acid and  hydrochloric  acid essentially free from dissolved  sulfur dioxide to be used in a chlorine dioxide reactor is produced by reacting chlor-ine  and  sulfur  dioxide  in  at  least  two  reaction  zones.          In the bottom of a primary reaction zone the total amount of  sulfur  dioxide  needed  for  the  mixed  acid  production is introduced in an aqueous mixture of sulfuric and hydro-chloric  acid  containing  dissolved  chlorine  and  gaseous chlorine.  The  sulfur  dioxide  reacts  with  chlorine  in  the aqueous  phase  to  produce  sulfuric  acid  and  hydrochloric acid. The mixed acid produced in the primary reaction zone contains  dissolved  quantities  of  sulfur  dioxide  and  is forwarded  to  a  secondary  reaction  zone.  Chlorine  is  in-troduced  into  the  lower  part  of  the  secondary  reaction zone.  The  amount  introduced  can  be  the total  amount  of chlorine to be  used  in the  production of the mixed acid for the  chlorine dioxide  reactor, or it can be a part of that  amount,  the balance  being  introduced  in  the  primary reaction  zone.  The  amount  should  be  large  enough  for  a gaseous  chlorine  phase  to  leave  the  secondary  reaction zone. The produced mixed acid is withdrawn from the  lower part,  and preferably the bottom of the secondary reaction zone. At least a part of the mixed acid is introduced into a chlorine dioxide reactor.
