Abstract: ABSTRACT OF THE DISCLOSURE The system utilizes a heat engine which provides shaft power and heat such as a conventional diesel engine in which part of the shaft power drive a pump for fluid to be heated; for example, a cryogenic liquid.  The engine heat is used to heat and/or vaporize the cryogenic liquid in a heat exchanger.  The heat available from the engine for transfer to the liquid to be vaporized is proportional to the power level of the engine.  The heat required to heat the fluid to a desired temperature is proportional to the flow rate of the cryogenic liquid.  By providing a loading on the engine which is proportional to the fluid flow rate, a sufficient amount of heat is provided to effect complete vaporization of the liquid, the amount of heat being directly propor-tional to the flow rate of the liquid. The loading of the engine can be accomplished by a power absorbing hydraulic drive connected to the engine shaft with the hydraulic medium used to drive the cryogenic liquid pump.  A rotary hydraulic drive and multi-section rotary driven fluid pump is provided to achieve vibration free, smooth operation in simplified, closed loop hydraulic drive circuit.  A dual rotary system is also disclosed.

Abstract: PROCESS FOR PRODUCING OIL FUEL, BITUMENS AND ASPHALTITE              Abstract of the Disclosure A process for producing oil fuel, bitumens and asphal-tite by way of intermixing products selected from the group conisiting of sour goudrons and spent sulphuric acid with a hydrocarbon fraction comprising heating the hydrocarbon frac-tion prior to mixing to a temperature of from 10 to 450°C, introducing thereinto said products at a temperature of from 30 to 90°C, followed by contacting the components of resulting reaction mixture and separation, at a temperature of from 102 to 360°C, of the vapour-gas phase formed in the process. The  process is conducted under a pressure of from 0.1 to 20x105 n/m2 in a stepwise manner; in the first step there is added and simultaneously dispersed one part by mass of products selected from the group consisting of sour goud-rons and spent sulphuric acid in 0.5-80 mass parts of a hydrocarbon fraction heated to a temperature of from 102 to 260°C followed by contacting the components of the reaction mixture obtained in the first step; in the second step one part of the reaction mixture with the separated vapour-gas phase and obtained in the first step is introduced simulta-neously with dispersing in 0.4-90 parts by mass of a hydro-carbon fraction having temperature of from 120 to 450°C, followed by maintaining the reaction mixture and separat-ing the vapour-gas phase. The reaction mixture is maintain-ed in the first step for 1-150 seconds, in the secont step or 2-700 seconds.  Separation of said vapour-gas phase is effected upon spraying at a linear speed of dense jets of from 0.01 to 10.5 m/sec. During and after separation of the gas-vapour phase a gas carrier is supplied in an amount of from 0.02 to 1.6 m3/m2, sec. As the carrier gas use is made of nitrogen, steam, air, carbon dioxide or mixtures thereof.  To obtain bitumens as the hydrocarbon fraction use is made of high-molecular organic compounds or mixtures the-reof such as straight-run goudrons, deasphaltization asphalts, extracts resulting from selective purification of petroleum oils or mixtures thereof. To obtain asphaltite, into the reaction mixture a hydrocarbon fraction is added having tem-perature ranging from 10 to 120°C in an amount of from 1 to 60 parts by mass per one part by mass of the reaction mix-ture, followed by separation of asphaltite and recycling the hydrocarbon fraction to the process.    The present invention may be advantageously employed in petrochemical, oil-refining, coal-tar and other industries associated with the use of sulphuric acid as a reagent.

Abstract: COKE PRODUCTION            Abstract of the Disclosure In the delayed coking of a coking feedstock wherein the feedstock is continuously heated in a coking heater and introduced into a coke drum, the heater is operated to provide a coke drum temperature of from 415° to 455°C, and, after filling of the drum to the desired level, feed-stock introduction is discontinued and the coke drum contents are heated at a temperature of 450°C to 500°C, and which heating temperature is at least 10°C greater than the coking temperature, by passing a non-coking vapor through the con-tents of the drum to reduce the volatile combustible matter content to a value of 4% to 10% by weight and thereby re-duce the CTE of the formed coke.  The process is applicable to the production of needle coke from various kinds of feed-stocks, in particular from a petroleum feedstock wherein the feedstock is initially treated by thermal soaking in the pre-sence of sulfur, followed by thermal cracking to increase the aromaticity.  Noncrystalline substances may be removed prior to coking to further improve the process.

An inter-program gap detector detects the location of each inter-program gap on the record and produces an inter-program gap signal representing that location as the carrier moves the turn-table into the housing.  A selector is provided for selecting a program to be played back by selecting a particular inter-program gap signal which represents the location on the record of the desired program. A tone arm position detector detects the position of the tone arm as it moves across the surface of the record and produces a tone arm position signal representing the relative position of that tone arm.  A control circuit compares the tone arm position signal to the selected inter-program gap signal and produces a control signal when the tone arm position signal corresponds to the selected inter-program gap signal so as to cause the tone arm to play back the selected program.                             -i-

Abstract: GEAR SYNCHRONIZER FOR A POWER TRANSMISSION            Abstract of the Disclosure A synchronizer for a power transmission has a split cone ring rotatable with a ratio gear and a split bearing ring rotatable with the syn-chronizer ring.  During ratio change, the syn-chronizer ring transmits a normal force to the split cone ring which develops into axial and radial components.  The normal component imposes a first frictional torque on the cone ring while the radial component causes contraction of the cone ring about the split bearing to create a second frictional torque acting on the cone ring.  The contraction of the cone ring causes contraction of the bearing which frictionally engages a hub on the ratio gear and transmits a third frictional torque to the hub.  The three torques are additive to cause the ratio gear to accelerate or decelerate so that speed synchronizing between the shift ring, synchronizer ring and ratio gear will occur.
