Abstract: ABSTRACT OF THE DISCLOSURE   A method for winning lead from a powdery material consisting of a lead sulfide concentrate or a powdery material containing lead sulfide by passing an electric current across the anode and the cathode of an electrolytic cell partitioned into an anode compartment and a cathode compartment by a diaphragm; which comprises filling the anode compartment with a suspension of the aforesaid powdery material in an aqueous solution of a water-soluble chloride, electrolytically forming the crystalline particles of lead chloride by the anodic oxidation of the suspended particles, separating and refining the crystalline particles of lead chloride from the aqueous solution of the water-soluble chloride, and filling the cathode compartment with a solution of the separated and refined crystalline particles of lead chloride dissolved in an aqueous solution of a water-soluble chloride so as to deposit lead electrolytically on the cathode.  The inventive process is less complex than the conventional lead smelting process and it avoids the smelting process which poses a pollution problem.

Abstract: ABSTRACT OF THE DISCLOSURE       In a circuit breaker undervoltage release device, a spring powered trip slide is held in a latched position by a latch lever while the plunger of a solenoid is magneti-cally held in a seated position against the bias of a calibrated return spring.  In the event of an undervoltage condition, the spring retracts the plunger, causing the latch lever to release the trip slide, which then moves to trip the breaker.  Opening movement of the breaker mechanism first actuates a reset lever to load a reset spring and then returns the slide to its latched position.          As the latch lever regains latching control of the slide, the reset spring discharges to snap the plunger to it-seated position.

Title: Process for the continuous chlorination of  olefins in the liquid phase and an apparatus  for carrying out the process
Inventor: SCHMIDHAMMER LUDWIG
IPC: C07C17/02
Filed: 1979-01-25
Granted: 1982-08-03
Abstract: ABSTRACT OF THE DISCLOSURE             In the chlorination of ethylene in the liquid phase, an excess stoichiometric amount of chlorine is normally used in order to achieve as complete as possible a conversion of the ethylene.  Part of the excess chlorine reacts by substitution and thereby reduces the yield of desired 1,2-dichloroethane.  The unreacted excess chlorine therefore has laboriously to be removed in subsequent reaction steps. As a result of the method according to the invention to limit the chlorine excess to less than 600 ppm by weight in the reaction cycle, these disadvantages can be obviated.  The constant compliance with such a low chlorine excess without fluctuations is rendered possible in industrial operation by the arrangement according to the invention for the continuous recording of the chlorine concentration, even in the presence of catalysts.

Abstract: Abstract of the Disclosure A rotary retort furnace wherein the retort is supported for rotation at only one end outside of the heated furnace shell such that the retort is cantilevered into the shell.  The rotary retort has a charging door mechanism that cooperates with a skip hoist loading mech-anism to provide charges of the parts to be heat treated that are of a uniform size and are introduced into the retort so as to minimize the loss of any controlled at-mosphere.  The skip hoist loading mechanism has a vibrat-ing feed hopper that dispenses a weight controlled charge into a skip hoist bucket which, after receiving the pre-determined charge of parts, is held in a ready position until such time as a cam mechanism controlling the opening and closing of a door on the charge end of the retort causes the door to open and the skip bucket to be moved to a position wherein the parts are dumped into the retort for heat treating.  The internal auger flight for the retort is made by forming a number of toroids from a resilient material, radially cutting each of the toroids and deforming them to form individual flights, and connect-ing one of the split edges resulting from the cutting to the opposite edge of an adjacent flight such that an axially compressed helical subassembly is obtained,  The helical subassembly is then screwed onto a shaft having a number of guide pins axially on the shaft at predetermined spacings thereby both axially extending and radially compressing the helical subassembly.  The shaft and the helical subassembly are inserted into a retort shell and one free end of the subassembly is welded to one end of the retort.  The shaft is then unscrewed from the sub-assembly while at the same time being forced axially into the retort such that the edges of the helical subassembly fit tightly against the inside of the retort.  After the shaft has been removed, the remaining end of the helical subassembly is welded to the end of the retort.
