Abstract: ABSTRACT OF THE DISCLOSURE     A continuous casting plant, wherein at least one tundish car movable on a circular-arc-shaped pathway is used, which tundish car is pivotable around a column and is centered in horizontal direction by means of three guiding rollers and secured against tilting in vertical direction by two vertical supporting rollers; when two cars are used, one of the cars has a cranked longitudinal carrier; the column can be hollow and surround the ladle stand, and it can be vertically separated into two parts.  The construction is simple, trouble-free, the circular-arc-shaped pathway can be comparatively lightly built and the tundish cars can be operated independently of the working readiness of the ladle stand and remain operable even if the latter is out of order.

Abstract: Abstract of the Disclosure A light transmitting panel composed of at least two panes held in spaced relation by a spacer assembly to define at least one space between panes is given improved sound damping properties by giving such space a thickness of greater than 9 mm, by causing the space between panes to be sealed from the external atmosphere, and by filling this space with a gaseous medium composed of air and at least one other gas, the air constituting at least 30% by volume of the medium, and whose composition is such that the velocity of sound propagation therethrough differs by at least 5% from that in dry air at the same pressure and temperature as the medium.  Thus, the acoustical transmission through the panel is reduced.

Abstract: METHOD AND APPARATUS FOR THE PURIFICATION          OF WASTE GAS CONTAINING GASEOUS POLLUTANTS           Abstract of the Disclosure A process and apparatus for the purification treatment of a waste gas containing gaseous pollutants.  The process comprises the steps of upwardly moving the waste gas through a tower, provided in the interior with a multiplicity of sub-stantially horizontal shelves, and at the same time downwardly moving activated carbon particles through the tower, allowing the waste gas and the activated carbon to come into contact with each other and permitting the activated carbon to form a fluidized bed on each of the shelves, thereby causing the gaseous pollutants of the waste gas to be adsorbed on the activated carbon and consequently effecting the removal of gaseous pollutants from the gas.  The waste gas can be contin-uously purified and the activated carbon recycled.  The carbon particles employed are activated carbon spheres and perforated plates having a weir formed thereon are used as the shelves.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to drill screws with extending ears to ream a hole in object with the ears breaking off when the screw enters a second object in which a smaller hole is drilled.  The inventive screw is adapted to fasten two or more juxtaposed work pieces and it comprises a tip, a shank, and a head, a screw thread on a substantial part of the length of the shank, and means projecting from a part of the shank lying between the tip and the thread.          The projecting means is integral with the shank and operative in materials of less than a predetermined hardness to form a hole having a diameter at least as great as the pitch diameter of the thread, but being so weakly connected to the shank that, in materials of more than the predetermined hardness, the projecting means is broken.  The projecting means is of non-rectangular configuration  and is such that upon being broken there is substantially none of the pro-jecting means remaining which projects beyond the shank.

Abstract: Abstract of the Disclosure A method of protecting an electric permanent magnet motor (energized by a rectifying bridge which comprises at least two thyristors) against thermal overloading owing to accidental blocking of the driven element.  With the aid of an electronic circuit the small residual voltage (of a polarity opposite to that of the supply voltage) which appears at the terminals of the rotor of the motor during the second portion of each power supply half-cycle and which persists at the beginning of the next half-cycle, is selectively amplified; to the amplified voltage a fraction of the total voltage at the motor terminals is opposed and the resulting integrated and filtered voltage is utilized for controlling a transistor which substantially cuts off the power supply to the motor when said motor is blocked owing to the driven element being blocked.  The described method is especially intended to be used for protecting motors of laundry washing machines.

Abstract: AUTOMATIC HEMMING APPARATUS               ABSTRACT OF THE DISCLOSURE           An apparatus is provided having a continuous band of material passing through the stitching means of a sewing machine.  Pieces of material are manually placed individually on the band and hemmed to it at a side which has been folded under the band by a mechanical folder.  A sensing means senses the passage of an end of each piece which has had a portion raised from the band and in response activates a cutter which cuts away a strip of the band to which the piece was hemmed.  A removal means for moving the strip away from the band ant into a stacker is activated after the strip has been cut away from the band.  The stacker has a base supporting two spaced, upwardly extending sidewalls defining a passage therebetween.  Each of the sidewalls supports a ledge protruding into the passage.  A portion of the base is vertically movable and adapted to fit within the space between the ledges.  As the strip comes to rest in the passage, the movable portion of the base, upon being actuated by the sensing means, is raised above the ledges and then returned to its original position, leaving the strip resting on the ledges.

Abstract: ABSTRACT OF THE DISCLOSURE          This disclosure depicts an electron gun especially for use in a color cathode ray tube of the small-neck, shadow-mask type.  The gun design is also applicable to other television cathode ray tube displays that require a gun that provides small, symmetrical spots of uniform cross-section, such as guns used in monochrome television and beam index tubes.  The gun is comprised essentially of a four-element tetrode section and a main focus lens section.  The tetrode section generates at least one electron beam and a cross-over that is imaged on the screen of the tube focused by the main focus lens.  The tetrode section is characterized by having a strong prefocus; that is, a prefocus in which the electron trajectories are substantially refracted, or bent, before exiting the tetrode section.  The tetrode section has two associated grid means whose dimensions, configurations, and relative spacings, in combination with a strong electrostatic prefocusing field produced between said grids, forms in the grid interspace an electrostatic field which includes in the region of the beam strongly bent, preferably substantially hyperboloidal equipotential lines which help to suppress spherical aberration commonly associated with a highly refractive tetrode section design.

Abstract: ABSTRACT OF THE DISCLOSURE   An apparatus for continuously producing finished prestressed con-crete members along a prestressing bed with a plurality of prestressing members which extend along the prestressing bed and which are arranged to pass through the concrete members when formed. The apparatus includes a scaffold which spans the prestressing bed in a gantry-like fashion and is supported for movement in a direction parallel to the bed.  The scaffold is provided with at least two adjacent stations for producing the finished prestressed concrete members.  A number of vertically movable lower form members are carried on the scaffold for movement to a lowered position on the prestressing bed for receiving fresh concrete to form the concrete members. After the members are formed and bonded the lower form member may be raised away from the finished member.  Upper form members corresponding in number to the lower form members are also carried on the scaffold for vertical movement into and out of the concrete member forming position.  The upper form members are also horizontally movable longitudinally along the scaffold.  Thus with this apparatus fewer forms are necessary in a mechanized production of concrete members.
