Abstract: ABSTRACT           A method for hydrotreating used oils to second raffin-ates in the form of lubricating oils is provided wherein ecologic-ally undesired byproducts or wastes are avoided without requiring expensive separating steps or reaction conditions or the use of costly catalysts.  In particular, with this process highly con-taminated used oils, i.e. those having organochlorines, particularly PCB, chlorinated dioxins and dipherylene oxides, in concentrations above a certain limit, are likewise again usable as a second raffinate, particularly as lubricating oil; thus, they must no longer be destroyed, for example, in a high temperature inciner-ation process.  For this purpose the used oil is first of all merely freed from coarse solids and subsequently with the addition of hydrogen subjected to liquid-phase hydrogenation at pressures of preferably 150 bar and temperatures of preferably 350°C.  There-after, the reaction products are separated into the lubricating oil and in particular solids-bearing byproducts.

Abstract: The invention relates to a method and apparatus for treating non-ferrous metal drosses in order to recover the free metal contained therein.  The dross is heated by a plasma torch in a rotary furnace, preferably to a temperature above 800°C.  The plasma heating and rotary motion make it possible to recover metal from the dross without employing the conventional salt bath.  This means that the gases exiting the furnace can be treated more easily to remove pollutants and the solid residues can be discarded without risk of causing environmental pollution. By controlling the speed of rotation of the furnace, large dross lumps can be accommodated and so the conventional grinding and screening procedure of the dross can advantageously be eliminated.

Abstract: Abstract of the Disclosure An antenna arrangement for the base unit of a cordless telephone which consists of separate antennas for transmission and reception. A whip antenna is used for transmission, whereas the telephone Tip/Ring wiring is used for reception. The telephone Tip/Ring wiring operates as an antenna with a moderate distributed capacitance to ground. Radiation from the handset can be acquired almost anywhere along the house telephone wiring and can be then conducted to the cordless telephone base receiver by the same wire. Therefore, the telephone wiring serves dual purposes as an antenna and as a feed-line. Because the transmitter and the receiver of the antenna arrangement are isolated, the receiver input filter is simple and easy to tune. The transmitting whip antenna is considerably smaller than the conventional whip antenna used for both transmission and reception, and its filters are also easier to tune than when used in a duplexer configuration.

Granted: 1992-08-11
Abstract: ABSTRACT A refuse collecting tool for the sanitary collection of animal excrement or other refuse which is preferably not handled directly.  The device includes a tubular handle having a gripping portion attached to its upper end and a scoop, elliptical in cross-section, attached to its lower end.  The scoop is divided into opposing jaws which are hinged together along their top edges and constantly urged to a closed condition by coil springs attached to their end walls.  A rod extending through the tubular handle is provided on its top end with a lever which extends radially through slots in the tubular handle that are located beneath the gripping portion, and on its other end with a flat rectangular plate sized to fit within the center region of the closed scoop.  Upward pressure on the lever forces the opposing jaws of the scoop open as the rectangular plate is forced upwardly into the decreasing diameter of the top of the scoop. The rectangular plate also prevents collected refuse from entering and fouling the moving parts of the tool.  The advantage of the tool is its simple construction which renders it light weight, reliable in use, economical to manufacture and practically maintenance free.
