Abstract: A B S T R A C T           A process for economically converting carbo-metallic oils to lighter products.  The carbo-metallic oils contain 650° F plus material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalent of heavy metals content of at least about 4 parts per million.          This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 to about 1400° F, and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight.          The spent, coke-laden catalyst is separated from the stream of hydrocarbons formed by vaporized feed and resultant cracking products and regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen.  The regenerated catalyst is recycled to the reactor and contacted with fresh carbo-metallic oil.          A portion of the catalyst is withdrawn from the cycle, passed through a magnetic field to separate the mass of catalyst into high activity catalyst and low activity catalyst, returning the high activity catalyst to the cycle and disposing of the low activity catalyst.

Abstract: SWITCHING ARRANGEMENT FOR INCREASING STABILITY IN A POLYPHASE [E.G., 3-PHASE]      POWER SYSTEM FED BY A GENERATOR              ABSTRACT OF THE DISCLOSURE           Subsynchronous oscillations in a polyphase power network can be effectively damped with a switching arrangement having a thyristor-switched regulation and a phase shifting polyphase power system.  The arrangement is controllable and is periodic in nature, being responsive to a measurement signal representing a physical parameter of the subsynchronous oscillations.  This signal preferably represents the difference between the instantaneous rotational frequency of the generator and a set-point value for that frequency.  Control windings are connected in series with the power-network-side polyphase windings of a block transformer.  Voltages induced in these control windings are phase shifted with respect to the voltages in the respective associated power-network-side polyphase windings of the block transformer.  These voltages in the control windings produce a very effective damping torque on the generator, to damp out the subsynchronous oscillations.

Abstract: ABSTRACT        In some cases, it is necessary to coat aluminum with nickel, and the most difficult operating conditions are probably met here in the case of aluminum pistons in internal combustion engines. With known processes, adhesion problems occur in the further coating with other metals.  Without intermediate activation, satisfactory solutions are not obtained.  However, the problem is solved by high proportions of nickel sulfate, small proportions of an acid which stabilizes the pH values, and very small proportions of a fluoride which loosens the oxide layer appearing in the Licer bath, of a chloride which promotes the dissolution of the nickel anodes and of a phosphate which improves the adhesive strength of the nickel layer.  If solids, such as silicon carbide or boron carbide are present in the nickel bath, they are kept in suspension by vigorous circulation, for example by means of air.  The particle size should preferably be 3 micrometers.

Abstract: A B S T R A C T               The seat and back-rest of a chair are inclinably supported in bearings, for example of a foot-rest and are connected to one another by a joint.  The seat has a lengthening section extending against the back of the back-rest while the back is kept at a distance from the joint by means of a lengthening arm.  A spring element is attached at its ends to the free ends of the lengthening section and to the back.  While changing from the normal position (solid line) to the resting position, a relative motion is superimposed on the seat and the rest-lever during their rotating motion.  This relative motion leads to uneven lowering-lengths of the free end of the seat and the back section, upon the changing to the lengthening lever.  By means of this relative motion, the normally unavoidable "drawing out effect" with the user of the chair is avoided in course of which, however, additional pipes (as is the case with known designs) are not required.

Abstract: ABSTRACT        A mail collection system moves mail between a remote location and a base location along a continuous wire loop extending between said locations.  The wire loop is supported on pulleys and is rotatable in either direction by means of a motor.  Affixed to the loop, at opposite sides, are two containers for carrying mail.          The containers are located relative to one another so that the distance of one container from the base location along the loop is always equal to the distance of the other container from the remote location along the loop.  At the remote location, the loop is canti-levered and supported on a hinged beam so that the loop will swing away, rather than break, if it is struck by a snow plow or the like.  When mail is placed in a container in the remote location, the motor can be activated to move that container to the base location.          Simultaneously,  the other container moves to the remote location to await additional mail.

The canister has telescoping top and bottom parts that are, in the assembled canister, sealed together.  A filter for particulate material is molded in situ in the top part, while a separate adsorbent material cartridge is fitted into the bottom part,  In manufacturing the canister, the cartridge is manufactured separately, apart from the remainder of the canister so that it can be kept in a controlled environment so as to avoid possible contaminating due to a humid atmosphere.  The molding of the filter for particulate materials,normally a pleated paper filter, in situ and away from the cartridge avoids the requirement for a long adhesive drying time during which the adsorbent material in the cartridge is exposed to humidity.  The new canister also exhibits greater strength than the known canisters.

Abstract: ABSTRACT Of THE DISCLOSURE   An automatic transmission, for a vehicle with an engine, includes a hydraulic fluid pump which supplies pressurized hydraulic fluid. It is detected whether or not the engine is being started, and the pump output is controlled so as to be decreased when the engine is being started. If the pump is one whose output per one revolution of its input member is variable, then its output may be thus controlled by decreasing its output per one revolution when the engine is being started. And, if the pump is a variable capacity type vane type hydraulic fluid pump the output of which per one revolution of its input member is controlled by varying the eccentric position of a controlling member thereof, then its output per one revolution may be thus controlled by varying this eccentric position to give a pump output per one revolution decreased when the engine is being started. Alternatively, if the pump is a fixed capacity type electrically driven type hydraulic fluid pump the output of which per one revolution of its input member is substantially constant, then its output may be thus controlled by decreasing the rotation speed of its input member, possibly to zero, when the engine is being started. A system for implementing this method is also disclosed.
