Abstract: ABSTRACT There is provided a process for the simultaneous manufacture of pure MTB (methyl tert.-butyl ether) and a substantially isobutene-free mixture of C4-hydrocarbons, by reacting isobutene contained in a mixture of C4-hydrocarbons with excess methanol in the liquid phase at elevated tempera-tures on strongly acid, macroporous, organic ion exchange resins, character-ised by the following steps:  (a) methanol and isobutene are reacted in a molar ratio of  2:1 to 5:1 at temperatures between 30 and 100°C,  (b) uncon-verted hydrocarbon products are then removed as a top product under a pressure of 2 to 10 bars from a first rectification column,  (c) a bottom product from said first column is rectified in a second rectification column under normal pressure or under a slight excess pressure of up to 2 bars at the top of said second column, a bottom product from said second rectification  column is recycled to step (a), if necessary after separating off a portion of the tert.-butanol formed and the C8-olefines, and (d) a top product or distillate from said second column is rectified in a third rectification column under a pressure of 5 to 30 bars, obtaining a top product or distillate which is recycled to step (c) and pure MTB is withdrawn from the bottom of said third column.  Utilizing this process results in unconverted hydrocarbon products having an isobutene content of <0.25 per cent by weight.

Abstract: Abstract of the Disclosure Method and means for protecting earth dams from failure caused by overflow or internal (tunnel) erosion.  The invention provides a barrier between the dam and the impounded water in the form of a water-impervious covering for the vulnerable surfaces of the dam.  At the least the covering should sheathe the top and upstream face, but better protection is provided by extending the covering to the downstream surface.  The covering is flexible to conform to the contours and surface irregularities of the dam, and anchoring means are provided to secure the covering to the dam and to prevent or minimize seepage.

Abstract: TITLE                TIME JITTER DETERMINING APPARATUS                           INVENTOR                          Kamilo Feher ABSTRACT OF THE DISCLOSURE The jitter determining apparatus uses only a jittery clock signal of period Tb recovered from the received data signal to determine peak to peak jitter Jpp and jitter distribution.  The apparatus includes an  AND gate having a pair of inputs.  The inputs are coupled to a first signal which is the jittery clock signal delayed by a fixed amount nTb where n is preferably greater than 5, and to a second signal which is a jittery pulse signal generated from the jittery clock signal.  The second signal is also controllably delayed by a factor greater than twice the jitter Jpp.  The AND gate produces output pulses when coincidence occurs between the two signals as the delay of the second signal is selectively varied.  A counter counts the pulses for each selected delay position and thus provides the peak to peak time jitter Jpp of the clock signal.

Abstract: DEVICE FOR TEMPORARILY CLOSING DUCT-FORMERS  IN WELL COMPLETION APPARATUS                     ABSTRACT OF THE DISCLOSURE       A duct-forming device is disclosed for use in a well completion apparatus of the kind, wherein a bore hole casing is positioned in a bore hole and duct-forming devices of alkali- and acid-resistant metal - such as steel - are secured at spaced levels to the casing in alignment with holes machined in the casing wall.  In accordance with the invention, a closure device is arranged within the duct-forming device which permits flow of predetermined amounts of liquid, such as acid, from the interior of the casing through the duct-forming device and into the producing formation, while gradually being moved by the liquid into a position in which such fluid flow is prevented.          After the fluid flow has been stopped by the closure device and when the formation pressure exceeds the pressure within the duct-forming device and the casing, fluid from the formation then forces the closure device toward and into the casing space to permit thereafter free flow of formation fluid into the duct-forming device and the casing or of pressurized treatment liquid from the casing into the formation.

Abstract: RCA 74,559 Abstract The present invention describes non-linear circuitry for reducing intermodulation distortion occurring in signals recovered from a disc record.  The non-linear circuit generates complementary signals in a diode modulator for cancelling the undesired distortion components of the recovered signal.  A synchronous detector in a servo loop with the non-linear circuit samples the distortion component of the resultant baseband video signal and applies bias to condition the non-linear circuit to further reduce the distortion-components.  A reference signal for the detector is derived from the sound components of the recovered signal.

Abstract: ABSTRACT       Disclosed is a process for machining nickel-base superalloys wherein a thermal effect process, such as laser or electric discharge machining, is first used to remove material but leaves a recast layer.  Next a chemical milling process is used wherein the etchant only attacks and removes the recast layer.  The etchant is comprised by volume percent of 40-60 HNO3, 5-20 HC1, and balance H2O, with which is included 0.008-0.025 moles/liter FeC13 and at least 0.016 moles/liter CuSO4. The FeC13 improves removal rate but tends to cause unwanted pitting and intergranular attack.  These tendencies are inhibited by the addition of CuSO4, preferably the molar ratio of CuSO4 to FeC13 is 2:1.  The beneficial combination of FeC13 and CuSO4 is usable in other etchants.

Abstract: HEATED FUEL LINE          .          Abstract of the Disclosure A heated fuel line for preventing solidifying of fuel in the fuel line of an engine in extremely low-temperature environments includes an electrical resistance heating element positioned directly inside the fuel line.  A thin, tape-like heating element is preferably employed through the length of the fuel line between the tank and the con-nection to a fuel filter near the engine.  Lead wires extend from the downstream end of the heating element through a fitting which carries the leads to the exterior of the fuel line.  The heating element is preferably of a type including a pair of spaced conductor wires covered with and separated by a sheath of a radiation cross-linked polymer which has the property of becoming more conductive in lower temperatures and less conductive in higher tem-peratures.  At lower temperatures, where heating of the fuel in the line is most needed, the element therefore produces the greatest amount of heat.
