Abstract: ABSTRACT OF THE DISCLOSURE         In the manufacture of cold-rolled steel strip in various gauges, especially for wall-ironing and deep-drawing operations, the strip after annealing is coated with a liquid containing a phosphatizing reactant and preferably also a lubricant, the strip is then coiled to hold the liquid between the layers thereof and the retained heat within the strip is utilized to have a favourable influence on the phosphatizing reaction.  This material can be fabricated without undergoing the conventional skin-pass rolling, which is an economical advantage.  In one specific embodiment of the invention the strip after annealing is advantageously cooled to a temperature of approximately 100°C prior to the coating thereon of the phos-phatizing and lubricating liquid.  In another embodiment of the invention the liquid coated onto the strip contains only the phosphatizing reactants and the lubricant is separately applied if needed upon the uncoiling of the strip.

Abstract: ABSTRACT      This invention comprises a method of achieving a highly effi-cient use of catalyst in conducting hydrogenation reactions of hydro-carbons in the liquid state by means of solid catalysts. The cata-lyst is wholly contained in a microporous layer no thicker than 200 microns deposited on the outside surface of otherwise inert support particles.  The catalyst particles, of the order of 10 mm diameter, are contained in a fixed, vertical, packed bed, and are brought into contact with the liquid hydrocarbon and hydrogen by passing the two fluids in cocurrent flow, either upwards or downwards, through the bed at substantially greater gas velocities than are usually employed in fixed bed catalytic reactors used for hydrogenating hydrocarbons in the liquid state.  The effect of the heat gas velocity is to achieve substantially higher heat and mass transfer rates among the three phases (catalyst, liquid hydrocarbon, and gaseous hydrocarbons in the are achievable under conventional conditions of operation of fixed bed catalytic reactors used for hydrogenating hydrocarbons in the liquid state.  The combined effects of the high gas velocity and the mode of deposition of the catalytically active components on the cata-lyst support, are the achievement of a large global reaction rate in the reactor, combined with a high internal effectiveness factor for the catalyst.  For fast hydrogenation reactions, for which the inven-tion is most advantageously employed, a comparable efficiency of cata-lyst utilization can at present be achieved only by using catalyst in the form of powder or granules so small as to preclude their use in a fixed bed reactor.

Abstract: INTERPOLATION AND CONTROL APPARATUS AND METHOD FOR A NUMERICAL CONTROL SYSTEM            ABSTRACT OF THE DISCLOSURE          A numerical control system having both linear and circular interpolating capabilities is described.  Data from a permanent storage medium such as tape are input to a preprocessor.  The preprocessor processes the data into a form acceptable to the system logic and makes all parameters for both linear and circular interpolation available to the system logic. Because linear interpolation is used, straight lines as well as arbitrary curves which are simulated by a series of short straight line segments can be drawn or cut.  Additionally, because circular interpolation is used, arbitrary curves can be simulated by a series of arcs, each of the arcs being a portion of a different circle and the various circles having varying radii in accordance with the dictates of the arbitrary curve being cut or drawn.  The ability to use both circular and linear interpolation substantially reduces the data processing because the interpolation technique requiring the least definition can be conveniently employed.  Also, because of the particular interpolation techniques employed, a minimum of multiplication and division is required so that the system logic is substantially reduced.  Additionally, because of the particular linear and circular interpolation techniques and because of the data processing technique employed, the execution time of real time tasks is reduced.  This results in a substantial reduction in demands on the computing capabilities of the system, thereby significantly increasing the overall capabilities of the system.

Abstract: ABSTRACT           A reel motor drive system using a first and a second signal for comparing an error signal derived from a tape tension sensing transducer with a respective polarity of separate positive and negative repetitive ramp signals.  Each comparator produces an output signal as a series of constant frequency, duty cycle modulated pulses having a duration equal to the time that the error signal is greater than the ramp signal being compared thereto.  These pulses are used as drive signals to a reel motor through a motor power amplifier and are used to develop mutually exclusive steering signals for selecting a motor drive direction by means of a steering logic circuit.  The steering signals are also applied to the motor power amplifier to select a current path through the reel motor corresponding to the desired motor drive direction.

Abstract: Abstract A centrifuge rotor having a sealing element which auto-matically controls in response to the centrifugation operation the fluid communication between separate fluid mixture chambers within the rotor.  The sealing element is situated within the rotor above an annular and an inner chamber used for containing a fluid mix-ture.  When the rotor is assembled and stationary, the sealing ele-ment establishes a seal between the respective chambers.  During the rotation of the rotor in a centrifuge, the centrifugally in-duced pressure exerted by the fluid mixture moves the sealing ele-ment, releasing the seal between the respective chambers and al-lowing fluid communication between the chambers.  As the rotor re-turns to a stationary position and the centrifugally induced pres-sure of the fluid mixture subsides, the sealing element automati-cally re-establishes the seal between the respective chambers.
