Abstract: ABSTRACT   In a process of reacting a hydrocarbon with steam and/or carbon dioxide in a reaction zone heated by a combustion furnace to give olefins or process gas containing carbon oxides and hydrogen high grade heat is recovered from furnace flue gasses and/or process gas whereby to cool such gases to 150-300°C.  When the process gas is used in a synthesis of for example methanol or ammonia, gases at 150-300°C are also produced.  Previously the recovery of heat fro such low grade heat sources has been inefficient or inconvenient.  According to the invention the best is recovered by means of an intermediary liquid coolant, which is brought into direct heat exchange with streams to be used in the process.  Preferably the liquid is water under pressure and is brought into direct heat exchange with a gas to be fed to the process; by this means 10-30% of the stream used can be provided from low grade waste heat.

Abstract: ABSTRACT:      An electronic telephone network suitable for use with a two-wire telephone line includes a low-output dynamic microphone coupled to a preamplifier.  The output signal of the preamplifier is coupled through a first equalization network which is responsive to an equalization signal which is related to the DC line current to equalize the frequency and amplitude spectrum of the transmitted signal irrespective of the telephone line length or loss.  The output of the equalization network is applied to a line-driver amplifier, and as a first input to an electronic signal separator or hybrid.  The output of the line-driver is coupled to the two-wire line, and as a second input through the separator by way of an attenuator.  The output of the separator is coupled to a receive amplifier by way of a second equalization network which is also responsive to the equalization signal to equalize the frequency spectrum of the receive signal as a function of line length.  The loss of the attenuator is selected to be equal to the gain of the line-driver thereby to isolate the transmitted signal and to pass the receive signal to the receiver amplifier.  In a preferred embodiment, the equalization signal is the DC supply voltage derived from the telephone line itself.  The output impedance of the line-driver is lowered during transmit to reduce the sensitivity of the separator isolation and, therefore, the sensitivity of the sidetone signal. The various circuits of the network utilize active load and other circuitry to provide maximum transmit signal dynamic range even at low line terminal voltages.

Abstract: COATING OF METAL Abstract of the Disclosure Aluminum diffusion can be effected from continuous coatings of leafing-type aluminum particles and such leafing coatings in very thin layers are more effective than coatings of non-leafing aluminum, with or without diffusion.  Other protective metals in flake or leaf form can be substituted for or added to the leafing aluminum.  Adhesion of the flakes to the substrate is greatly improved and can be effected at lower temperatures if the flakes are applied from a dispersion containing a vola-tilizable halogen-type carrier or an ammonium chromate.  The leafing coatings can be sprayed on from aqueous dispersion containing wetting agents and if desired a polyethylenetrtra-fluoroethylene and/or mixtures of phosphoric acid, chromoic acid and magnesium, aluminum, calcium or zinc salts of these acids. A protective second coating of such mixtures can be applied as a cover layer over the layer containing the leafing aluminum, and this combination works best on a ferrous metal that has an aluminum diffusion coating, particularly a ferrous metal that contains less than 1% chromium and has such an aluminum diffu-sion coating.  It also works very well on aluminum diffusion coatings from packs containing chromium, or chromium and sili-con, in addition to the aluminum.

Abstract: Abstract A carrier having a wheeled, open-ended, frame pivotally carrying an open-ended cradle so that the frame and cradle can be maneuvered around a pot and under projections on the pot.  A pair of primary linear actuators on the frame are coupled through levers and links so as to cause the cradle to lift the pot for transport and thereafter dump the pot by tilting the cradle more than 140° while maintaining good mechanical advantage.  Secondary cylinders are positioned to bear traveling loads, eliminating the pressure in the primary cylinders and the forces through the links and pins.  The levers and links are designed so as to avoid twisting and binding under heavy loads.

Abstract: Abstract of Disclosure There is disclosed a pivot and support mounting ar-rangement for a pivotal door arrangement which permits the door to be adjusted quite easily with respect to the door frame. The arrangement includes a pintle assembly carried by the door and a support arrangement mounted proximate to a lower corner of the door frame, and receiving a projecting portion of the pintle assembly.  The support arrangement includes a bracket having an elongate channel-like opening in which is mounted a pintle support block, and selective engageable means to prevent relative movement.  A recess is formed in the pintle support block to receive the pintle end portion, and spring means is associated with the support block tending to bias it upwardly. In the assembled condition the weight of the door will overcome the biasing force provided by the spring and the engageable means will be inter-engaged to preclude movement of the support block relative to the bracket.  When it is desired to adjust the door position, the door is lifted and the spring means will produce disengagement of said engageable means, while maintaining a degree of engagement of the pintle end in the block recess. Accordingly, movement of the door will produce movement of the support block relative to the bracket, such chat when the door is released the inter-engageable means are re-engaged to establish a new location for the pivot provided by the pintle means.

Abstract: PROCESSOR FOR INCREASING THE                RUN-LENGTH OF FACSIMILE DATA     Abstract of the Disclosure A facsimile scene typically includes a plurality of lines, each line having a plurality of picture elements (pels).  Often, pel signals are adaptable for run-length coding, a run being one or more successive pels having the same brightness level.  To increase the length of a run and hence to permit a more efficient use of a transmission link, a processor is disclosed for permuting a measure of the pel signals responsive to a reference signal.  Illus-tratively, the reference signal is the pel signal from a previous line.  In one exemplary bi-level pel signal embodiment, the measure is the current pel signal.  Specif-ically, if the reference pel signal is a logic one, the current pel signal is loaded beginning at one end of a memory; if the reference pel signal is a logic zero, the current pel signal is loaded beginning at the other end of the memory.  In a second embodiment, the measure is an error signal for indicating a difference between the reference signal and the current pel signal.  But for load-ing the error signal rather than the current pel signal, the operations aforedescribed are again followed.
