Abstract: ABSTRACT OF THE DISCLOSURE:            A method and device for controlling the temperature in fluid bed catalytic reactors operating at high temperature.          A controlled and adjustable amount of water is fed to a cooling device consisting of heat exchange tubular elements arranged inside the fluidized bed, the amount of water introduced being such that the water is thoroughly evaporated, the generated steam is superheated under a further heat absorption, at high temperatures, from the fluid bed, and the control of the heat exchange and therefore of the fluid bed temperature is effected by regulating the amount of water fed.  The temperature control device of the invention comprises a plurality of heat exchange tubular elements arranged vertically and in parallel relation-ship and each consisting of a pair of inner and outer coaxial tubes, the outer coaxial tube being closed at its lower end and being connected, at its upper end, with a superheated steam horizontal manifold, the inner coaxial tube ending a short distance above the lower, closed end of the outer coaxial tube and being connected, at its upper end, with a water-feeding horizontal manifold, whereby a countercurrent flow of the water fed is achieved inside the coaxial tubes; the inner coaxial tube is connected with the water manifold through a nozzle having dimensions such as to cause a pressure drop sufficient to permit an easy regulation of the water flow and a uniform water distribution in all of the tubular elements.   The invention permits a perfect, thoroughly automatic thermoregulation with a variability range up to +1°C also for high operating temperatures of the reactor and allows a direct generation of steam at high pressure with an adequate superheating degree.

Abstract: BACKGROUND OF THE INVENTION           (A)  FIELD OF THE INVENTION           The problem of water pollution from liquid petroleum products and like fluids having a density less than that of either fresh water or sea water has become of major concern throughout the world in recent years.  Such pollution of the water results from the handling of the oil or other fluids either in transporting or storage on or near the water, which oftentimes results in accidental spillage or leakage of oil onto the water surface, as well as from the use and discharge of the fluids into the water.  When such spillage, leakage, or discharge occurs, the oil must be removed as promptly as possible since the oil will tend to spread on the surface of the water and will be carried by the current of the water over great areas.

Abstract: Abstract of the Invention To permit the processing of hydrogen sulfide-fixed nitrogen compound feed streams, e.g. H2S-NH3 mixtures without causing plugging problems usually encountered in a Claus sulfur plant due to the formation of solid nitrogen sulfur salts, a first hydrogen sulfide feed containing substantial quantities of fixed nitrogen compounds, a portion of a second hydrogen sulfide feed essentially free of fixed nitrogen compounds and air are combined in a first thermal reaction zone where the amount of oxygen present is sufficient to achieve a high flame temperature for essentially complete conversion of the fixed nitrogen compounds to inert nitrogen, but insufficient to consume all of the hydrogen sulfide present.  The effluent of the first reaction zone is combined with the balance of the second hydrogen sulfide feed in a second thermal reaction zone where hydrogen sulfide and sulfur dioxide react to form sulfur.  After sulfur condensation, the gas stream is passed to the conventional catalytic Claus conversion stage zone. There is also provided an improved reaction furnace for use in the process.

Abstract: ?bstract of The Disclosure A method of treating steel pipe made by forming and welding a mother plate.  The pipe is shrunk in the radial direction by applying compressive radial pressure to the outside surface of the pipe to reduce the pipe diameter by at least about 1%.  The shrinking of the pipe increases the circumferential compressive yield strength and decreases the circumferential tensile yield strength.  The pipe is then heated to a temperature below the transformation temperature of the steel but high enough to increase the circumferential tensile yield strength of the pipe, preferably at least about 15% above the tensile yield strength of the mother plate.  The heating step does not significantly decrease the high circumferential compressive yield strength of the pipe.  The pipe is preferably heated to a temperature within the range of from about 500°F to about 1000°F, and the preferred heating technique is induction heating.

Abstract: ABSTRACT OF THE DISCLOSURE          A vibration isolator of the type used for mounting industrial equipment, having the capability of measuring forces exerted upon the isolator to adjust the support pro-vided by each of the isolators upon which the equipment is mounted so as to provide the most suitable distribution of support and to reduce the transmission of dynamic forces created by the operation of the equipment.  The isolator com-prises a resilient base, a bearing plate on the base and a sensing device cooperating therewith, with or without means for attaching the isolator to the equipment.  A force applied to the isolator exerts pressure on the bearing plate which is transmitted therethrough to the resilient base causing each of them to experience some deformation.  The sensing device detects the pressure or deformation caused by the force applied to the isolator and generates a signal corresponding to said force.  The signal is transmitted to indicating instruments suitably calibrated to show the static and dynamic forces to which both the equipment and foundation are subjected, as well as the weight and center of gravity of the equipment.

Abstract: PROGRAMMABLE FREQUENCY DIVIDER FOR A TELEVISION RECEIVER FREQUENCY SYNTHESIZER               Abstract of the Disclosure A phase locked local oscillator loop of a fre-quency synthesizer tuning system for a television receiver includes a programmable frequency divider for deriving an output signal having a period which is N times the period of its input signal, N being the number in MHz of the local oscillator frequency required for tuning the receiver to a selected channel (e.g., N = 101 for U.S. channel 2).  The "divide by" number N is controlled by first counting the input signal pulses in groups of (S) pulses, where (S) is a factor equal to the channel separation in MHz (6 in the U.S.).  Counting by groups of S continues until the number of such groups equals the channel number, e.g., 2 for channel 2, 83 for channel 83, and then continues for an additional predetermined number of groups of S dependent on the band in which the selected channel resides.  The counting then continues in groups of T (T = S-l is usual) far another predetermined number of groups, likewise de-pendent on the channel band, until the correct number N of input pulses have been counted, in groups of S and T counts.  When the correct N is reached, an output signal is generated and the process is repeated.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of laying an underwater pipe line under an ice sheet. The pipe is fabricated on shore at a make-up point and a plurality of sup-port stations are spaced apart along the pipe path.  Holes are bored in the ice at the support stations and low friction pipe support cradles are lowered underwater at the stations and anchored to the ice sheet.  A trench is then cut in the ice and the pipe string is introduced into the water and towed across beneath the ice surface through the support cradles by means of pulling winches at a winching station or stations.  As the leading end of the pipe being towed under the ice passes each support station the pipe support cradles are tightened so as to support the pipe string from the ice sheet and immediately beneath it.  After the pipe has been towed to the opposite shore, the pipe is lowered to the water bottom by attaching a train of lowering winches to the pipe through the trench.  Each of the lowering winches take up the support of the pipe and lowers it in turn to the water bottom as corresponding support cradles are released, one after the other.
