Abstract: The mineral acid catalyst is removed from the prod-ucts of cumene hydroperoxide cleavage by contact with an aqueous solution of an inorganic salt and an excess of an alkali metal hydroxide or phenate in a first zone. Suitably the aqueous solution contains so-dium sulphate and sodium hydroxide or phenate. The aqueous layer is removed and the organic layer con-tacted in a second zone with an aqueous solution com-prising an inorganic salt and sufficient weak acid to decompose any phenate carried over from the first zone. Suitable weak acids are oxalic and citric acids but the preferred acid is carbonic acid formed 'in situ' by passing carbondioxide into the aqueous inorganic salt solution.

Abstract: ABSTRACT OF THE DISCLOSURE One or more solid-state static converters change a first current frequency to a second current frequency such as, for example, A.C. to D.C., D.C. to A.C., or A.C. of one frequency to A.C. of another frequency such as in a cyclo-converter or the like, and operates a motor to drive a traction sheave to control the movement of an elevator car.  In one embodiment, a first solid-state static converter receives a three-phase A.C. input and directly supplies current to a motor armature circuit to control the movement of the elevator car in response to an error signal derived by the summation of a speed signal from a tachometer and a vehicle speed command signal while a second solid-state static converter receives a three-phase A.C. input and directly supplies current to a field circuit of the motor in response to the operation of a field gating control circuit.  With A.C. operation, three gating channels corresponding to the three source phases provide summing circuits receiving alternating phase reference signals through lead-lag filtering circuits, disable signals responsive to the source phases through lag filtering circuits, constant reference signals for continually providing sixty electrical degrees of conduction of the controlled rectifiers during each source cycle and providing a predetermined field current, and a field energy command signal supplied from a second summing circuit.  A command signal supplied by the system supervisory control, a field current indicative feedback signal and an armature current indicative signal are directly summed at the second summing circuit to provide the field energy command signal to the first summing circuit.

Abstract: CONTINUOUS REFLUX REFINING OF METALS                   ABSTRACT OF THE DISCLOSURE           A method and apparatus are described for the continuous refining of an impure metal.  The invention comprises providing a column consisting of a slurry of metal crystals in liquid metal, the column having a relatively cool zone and a relatively hot zone and a continuous temperature gradient between said zones.          The temperature of the cool zone is such as to permit coexistence of liquid and crystalline metal, and the hot zone is at a temperature sufficient to melt the crystals.  A portion of the column in the cool zone is chilled to form a coherent mass of crystals of the metal and then incipient melting in the mass is allowed to occur to release crystals from the mass into the column of the crystals in the liquid metal in the cool zone of the column. The crystals are transported through the temperature gradient and into the hot zone, where melting of the crystals occurs and the hot zone thereby becomes enriched with the pure liquid metal.

Abstract: Abstract of the Disclosure The invention relates to refractory shapes for use in the lowermost courses of the walls of ladles and the like where an adjustment for a taper may be necessary.  Each shape has opposed side surfaces, one of those surfaces having a thickness greater than the other surface, the side surface as being planar and substantially parallel.  The shape also has opposed upper and lower surfaces, one of the upper and lower surfaces being relatively flat, the other being arcuate.  In addition the shape has opposed end surfaces, the end surfaces being respectively convexly curved and concavely curved.  When two layers of the refractory shapes are used in a metallurgical vessel, the lowermost layer will have an arcuate upper surface and the uppermost layer will have an arcuate lower surface, meeting with the arcuate upper surface of the lowermost layer.          The uppermost ring of shapes is thus adapted to rotate on the lowermost ring of shapes toward and away from the metal shell to provide a relatively square relationship with the metal shell.

Title: Rf leak detector
Inventor: SHIMP RICHARD L
IPC: H04B3/46
Filed: 1977-04-20
Granted: 1980-01-15
Abstract: ABSTRACT       The detector is primarily useful in detecting RF leaks in a TV cable.  RF leaks are detected by transmitting a coded signal and using a very narrow band receiver to detect the code thereby differentiating between small amounts of RF leakage from the cable and extraneous locally generated RF energy.  The leakage from the TV cable may be due to small cracks in the cable, loose fittings or other non-RF tight conditions.  The detector is a three-part system including a transmitter, a remote cable powered preamp and antenna assembly, and a narrow band receiver providing an audio output. The transmitter is designed to be permanently installed at the head end location and is modulated with a unique audio tone. An RF leak is detected by moving the remote preamp and antenna assembly along the cable sheath.  When the remote preamp and antenna assembly picks up leakage RF energy, the unique audio tone will be detected, and the detected audio signal fed to a loud speaker or earphones.  The audio tone is readily recognized by the operator.

A terminal fastening section of the cap is folded back under and against the inner face of the next adjacent similar cap to form a longitudinally continuous connecting seam for the cap.
