Abstract: ABSTRACT OF THE DISCLOSURE A fast set up tooling arrangement for a coil placing machine is disclosed wherein the finger elements or blades which support coils as well as a magnetic core into which the coils are to be placed, as well as the reciprocable ram actuated stripper which is movable along those finger elements to engage and move coils into the magnetic core are readily adjustable axially of the ma-chine to accommodate changes in the height of the magnetic core or stack.  The arms which grip the core and the length of insulating wedges to be placed in the core may also be adjustable.  The axial extent of the finger elements or tooling blades as well as the axial distance traveled by the stripper are simultaneously adjusted by imparting a relative rotary motion between the stripper and finger elements on the one hand and a finger support shaft and stripper actuating ram on the other hand with the respective ro-tated and fixed elements being threadingly interconnected.     To effect stack height adjustment the stripper and its ac-tuating ram are moved to their extended position at which a key interlocks the stripper actuating ram and a threaded finger sup-port shaft to prevent relative rotation therebetween.  The strip-per and finger elements are also interlocked in this position and in one embodiment a driven gear arrangement engages and rotates the actuating ram and threaded finger support shaft to move threadingly mated second stripper engaging ram portion and a threaded finger holder having the finger elements disposed about its periphery.  In another embodiment when the stripper is exten-ded and the ram and threaded tooling shaft are rotationally inter-locked, neither is allowed to rotate, and a somewhat conventional tool indexing arrangement rotates the stripper and finger elements, causing their respective axial movement.

Abstract: ABSTRACT              The invention is concerned with a process and an apparatus for the thermal treatment of untreated aqueous sludges which contain combustible matter.  The untreated sludge is thermally thickened by heat exchange with oxidation products obtained from oxidation of pre-viously thickened sludge, and the thickened sludge is oxidized to generate gas and steam oxidation products by natural oxidation processes carried out in the gas phase at temperatures above the critical temperature  of steam.          The oxidation products are heat exchanged with incoming untreated sludge to thermally thicken the untreated sludge, whereby the steam oxidation product is condensed.        The phases of the oxidation products are then separated and recovered for further uses.

Abstract: ABSTRACT OF THE DISCLOSURE      A heater for controllably heating liquid in a container includes a substantially flat, elongated pad which is electrically non-conductive and is adapted to receive the liquid bearing container on one of its sur-faces.  An electrical heating device is embedded in the pad and is adapted to heat the end portions of the pad but not a central portion thereby defining heated and non-heated sections, respectively.  A first thermostat, associated with the heating device, is in the non-heated section and is adapted to monitor the temperature if the container at its interface with the pad and limit the temperature to which the container can rise during heating.  A second thermostat, associated with the heating device, is in the heated section and is adapted to monitor the temperature of the heated section and limit the temperature to which the heated section may rise during heating.    The method includes placing a container with a prescribed amount of liquid on a surface of an electrically non-conductive heating pad having a controllable electrical heating device embedded therein.  Heat is applied to the container from the end portions of the pad only, which constitute the heated section thereof, a centrally located portion of said pad being a non-heated section.          The maximum temperature to which the interface of the container and the pad can rise during heating is limited to a first predetermined temperature; the maximum temperature to which the heated section can rise during heating is limited to a second predetermined temperature, the second predetermined temperature being higher than the first predetermined temperature.  In this way, the liquid in the container is controllably heated to the desired temperature which is approximately that of the first predetermined temperature.

Abstract: METHOD OF MATERIAL PROCESSING UTILIZING AN INTERRUPTED BEAM OF CONTINUOUS WAVE LASER RADIATION               ABSTRACT OF THE DISCLOSURE     A method of material processing, in particular welding, utilizing high frequency interruption of a continuous wave beam of radiation is disclosed.  The pulses of laser radia-tion are generated at a pulse repetition rate more rapid than the thermal response time of the material, typically greater than one kilohertz, wherein the material reacts with the pulses such that the characteristics of the surface reflectivity of the material are dominated by the peak power in the pulse and the characteristics of the melting of the material are controlled by the average power of the pulses.  The duration of each pulse is controlled to be less than the time required to generate a beam absorbing plasma adjacent the weld zone. The absence of beam absorb-ing plasma and the efficient destruction of the reflectivity of the surface of the material results in increased welding efficiency and/or increased welding speed.

Granted: 1982-06-29
Abstract: ABSTRACT OF THE DISCLOSURE A novel process is proved herein for producing propylene-ethylene block copolymers by a three-step polymerization technique using a stereoregular catalyst.  The first-step polymerization is carried out by supplying propylene alone or a propylene/ethylene mixture so that the ethylene/ propylene reaction ratio is 6/94 or less, thereby polymerization 60 to 95% by weight of the total polymerization amount.  The second-step polymerization is carried out by supplying a propylene/ethylene mixture so that the ethylene/ propylene reaction ratio is 41/59 to 69/31, thereby polymerizing 1 to 20% by weight of the total polymeriztion amount.  Finally, the third-step polymerization is carried out by supplying ethylene alone or a propylene/ethylene mixture so that the ethylene/propylene reaction ratio is 90/10 or more, thereby polymerizing 4 to 35% by weight of the total polymerization amount.  Each polymerization step of the first to third steps is carried out batchwise.  The process described above can given propylene-ethylene block copolymers which are markedly well balanced in impact strength, stiffness, transparency and impact blushing.
