Abstract: ABSTRACT            A centrifugal mill comprises a cylindrical grinding drum, which performs a rotation about its own axis and a revo-lution in a circular orbit about a stationary axis of revo-lution, which is parallel to the axis of the drum, at a cons-tant speed ratio between said rotation and revolution. The distance form the drum axis to the axis of revolution is smaller than the radius of the grinding drum.  A feeder is provided at one end of the grinding drum.  Discharge means are provided at the other end of the grinding drum.  The feeding and discharge zones of such mill are subjected to wear and grinding elements may be thrown out of the mill.  This is prevented in that the grinding drum is provided at each end with a generally conical extension, a volute feeder is mounted on the generally conical extension at the feed end, and the generally conical extension at the discharge end is provided with discharge openings in its peripheral wall near its axially outer end.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for synchronizing switching mechanisms or program sequences to an external frame clock pulse, wherein after a given period of time the switching mechanism or program is enabled to be reset and that after this enabling the resetting takes place with the edge of an external clock pulse.          Moreover, the resetting takes place immediately after enabling if the edge of the external clock pulse has appeared earlier in time and the resetting takes place in any case no later than after a further given period of time even if the edge of the external clock pulse has not arrived.   An apparatus for carrying out the method is also disclosed.

Abstract: C-1951(SWGR/SPO) TIMING CIRCUIT FOR AN OVERCURRENT RELAY             ABSTRACT OF THE DISCLOSURE         A timing circuit for use in an overcurrent relay is disclosed.  A plurality of non-interacting R-C circuits whose outputs are summed is provided.  The signal representing the summed outputs of the R-C cir-cuits represents one term of the inverse time-current; relation it is desired to emulate.  Each time the summed signal reaches a predetermined level, a pulse is generated. The frequency of the pulses determines the length of a time delay before the protected circuit is interrupted. When it is necessary to take the second term of the time-current relation into account, this can be done by providing a multivibrator that emits pulses of an adjustable duration responsive to the summed signal and that itself triggers the generation of the pulse train constituting the timing circuit output.

Abstract: Abstract of the Disclosure A coating system utilizing application under vacuum technology in which entrance and exit ports for the material to be coated are defined by a pair of horizontal gates and a pair of vertical gates at the inlet and outlet apertures of the coating chamber.  A mounting arrangement at each port mounts the top vertical gate and the two horizontal gates in sliding relation with associated edges of the inlet and outlet apertures.  Positioning arrange-ments are provided for each of the slidably mounted gates for setting an initial position of the associated gate, and each gate is provided with spring means for biasing that gate toward its initial position.  A dimension sensing-adjusting arrangment is provided with a dimension sensing element mounted in the coating chamber by a mounting arrangement which enables the dimension-sensing element to detect strips of larger than normal thickness and automatically adjust the vertical position of the top vertical gate at the exit port to maintain clearance between the bottom edge of that gate and units of material passing through the exit port.  In one embodiment, a masking element  is provided between the entrance and exit ports to preclude application of coating material on preselected surface portions of material passing through the chamber.

Abstract: IMPROVED PROCESS FOR PRODUCTION OF ETHYL ACRYLATE     ABSTRACT         A process is provided for the continuous production of ethyl acrylate from ethylene and acrylic acid in the presence of sulfuric acid.  The process includes the removal of impurities from the reaction system by passing minor portions of sulfuric acid residue from the process through a wiped-film evaporator whose initial sections are heated to a specific temperature range and whose last or withdrawal section(s) are cooled to a specific temperature range. This treatment prevents foaming of the used sulfuric acid residue.  The treated sulfuric acid residue in the wiped-film evaporator is withdrawn from the reaction system.          If foaming of the sulfuric acid residue occurs, the foamed residue can back up into the reaction system requiring a shutdown of the entire process. An additional aspect of this process is the passing of at least 50 weight percent of the ethyl acrylate product residue from the finishing distillation tower into the wiped-film evaporator at the same time that the sulfuric acid residue is being treated.  The treatment of the ethyl acrylate product residue recovers additional ethyl acrylate product and acrylic acid starting material from the wiped-film evaporator while the remainder of the ethyl acrylate product residue containing polymerization initiators which can cause undesirable polymerized product, is removed from the reaction system.

Abstract: ABSTRACT OF THE DISCLOSURE:         Apparatus for squeeze casting of metals and alloys involving the action of increased gas pressure on the solidifying melt.  In this apparatus, the pres-suririzing of the gas is effected automatically during the idle stroke of the press and the high gas pressure is applied on the processed material immediately after the closing of the die.  To achieve this object, the apparatus comprises a hydraulic press with pressing cylinder and a piston dividing this cylinder in two spaces, connected to the hydraulic system of the press, and a piston rod to which there are fastened the press plate and the die.  At least one cavity is formed in the die, which is connected by means of corresponding valves to the supply reservoir with gas under low pressure.          Within the piston rod there is formed a chamber, filled up to a fixed level with working liquid from the hydraulic system of the press.  The bottom part of this chamber is connected to the space of the pressing cylinder below the piston.  This space is connected to the hydraulic system of the press by means of a valve.          The upper part of the chamber is connected simultaneously by means of a check valve to a supply reservoir for gas and by means of a shut-off valve - to the die cavity.          The die cavity is connected by means of another shuff-off valve to the atmosphere.

Abstract: Abstract A starter drive for internal combustion engines is disclosed. The starter drive is mounted within the starter housing and connected to the motor driven shaft. The shaft has a threaded screw formed thereon near the armature of the starter and a cylindrical end portion. A screw sleeve member cooperatively engages the threaded screw of the motor driven shaft. A ring armature member is centrally mounted to the threaded screw member. A unidirectional clutch member connects the screw sleeve member, the ring armature member and the drive pinion gear. An engaging member holds the ring armature member to the starter housing when the drive pinion is advanced axially along the motor driven shaft by the rotation of the motor when the motor is activated. Thus, the drive pinion engages the engine ring gear such that the drive pinion is held in mesh with the engine ring gear and the total motor torque is transmitted to the engine ring gear until the motor is deactivated.
