Title: Method and device for recovery of scrap goods
Inventor: ALAVI KAMAL
IPC: B03C1/00
Filed: 1990-11-21
Granted: 1997-03-18
Abstract: Electronic scrap goods, for example, electronic components, cables etc., are successively and alternately mechanically crushed, magnetically separated and mechanically-physically separated, for example, by means of electrostatic separators.  The dust produced during crushing is pneumatically collected and filtered out.  The non-metal fraction as well as the magnetic and non-magnetic fraction are produced separately as granules and dust.  The metal fractions are suitable for subsequent pyrolysis-free, wet chemical and/or electrolytic separation.  The non-metallic fraction is disposable.  The method is distinguished by low energy consumption and high environmental compatibility.

Title: Electrical synthesis of palladium hydroxide compounds
Inventor: ABYS JOSEPH A
IPC: C25B1/00
Filed: 1992-10-26
Granted: 1999-01-26
Abstract: This invention embodies a process for synthesizing electrodialythically palladium ammine hydroxide for use in palladium plating baths. The electrodialysis takes place in a cell with a catholyte, a product and an anolyte compartments which are divided by a fluorinated anion permselective membranes. Catholyte solution readily supplies OH ions, raw starting solution contains palladium ammine ions and anions capable of migrating into the anolyte compartment, and anolyte solution readily absorbs the anions from the raw solution. Electrodes, placed in the outer compartments, are placed no more than 5 cm apart. The process is conducted with current densities of 500 ASF or less, with 200 ASF being preferable, with current efficiencies of 50 to 90 percent, with 60-80 percent being preferable, and at bath temperatures of from above freezing to 40°C, with 25-40°C being preferable. The electrodialysis results in a stable palladium diammine hydroxide solution containing a small fraction of starting palladium diammine compound, such as palladium diammine chloride, making the final solution readily useable either as a replenishing or a plating solution.

Title: Expanding tenon clamp
Inventor: JORDAN DAVID L
IPC: F16B7/14
Filed: 1993-03-08
Granted: 2003-11-25
Abstract: A clamp mechanism secures a lighting fixture to a mounting apparatus. A tenon is inserted into the open end of a mounting pole. A radially expandable element, mounted on the tenon, is adjusted to expand radially outwardly to engage the inner surface of the mounting pole. Radial outward expansion of the expandable element is imparted by a threaded bolt which threadedly engages a base of the expandable element. As the base is drawn towards the end face of the tenon, angled legs of the expandable element are rammed outwardly until distal ends of the legs frictionally engage the inner surface of the mounting pole.

Title: Optical mixing device
Inventor: JENKINS RICHARD MICHAEL
IPC: G02B6/28
Filed: 1991-12-02
Granted: 2002-02-12
Abstract: An optical mixing device (10) incorporates a rectangular multimode waveguide (14), with an input region (22) and an ou-put region (24), two square section input waveguides (26, 28), and a detector (34). The input waveguides (26, 28) are arranged to provide first and second input radiation beams respectively to the input region (22), each beam being in the form of a square waveguide fundamental mode beam. Modal dispersion along the multimode waveguide (14) produces a single maximum incident on the detector (34) when the input beams are in phase with one another, and two maxima of like magnitude located on opposite sides of the detector (34) when the input beams are in antiphase. Intermediate these two situations three maxima are produced, the amplitudes depending on phase difference. The first and second input beams may be of like frequency producing a time-inde-pendent device output. The input beams may alternatively have different frequencies. For instance the first input beam may be a local oscillator signal produced by a coherent source of stable frequency, and the second input beam may be a Doppler shifted version of an output signal from that source. The device output then provides an intermediate frequency signal. The intensity inci-dent on the detector (34) thus varies at the difference frequency of the two inputs. Similar devices may be constructed with addi-tional inputs and with different forms of output.

Title: Method of recycling rigid expended polyurethane
Inventor: KROSCH KARL
IPC: B29C43/04
Filed: 1993-03-12
Granted: 1997-03-18
Abstract: The recycling of used polyurethane foam is made possible by a process in which the starting material is first dried to a moisture content of 2 to 4% and is then filled into a multi-part mold (16, 17, 18) that defines the molded part (32).  The parts of the mold (16, 17, 18) are then, with generation of the necessary compression pressure of below 20 N/mm2, pressed together and locked.  These molds (16, 17, 18) that are subject to the compression pressure are heated in a tunnel furnace (20) so that the molding material reaches a temperature of approximately 130°C.  After a predefined holding time, the molds (16, 17, 18) can be opened under pressure and the molded parts (32) can be removed.  Molded parts (32) with a thickness of 42 mm and of corresponding size have been produced successfully with this process.  Instead of the molds (16, 17, 18), it is also possible that a two-part tool is used.  Also possible is the use of turntables (14, 41, 44), whereby the pressing and holding time can be shortened by adding an accelerator.  The process, which comprises only one pressing step, enables an approximately continuous operation.

Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene , oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of paliadium and gold, fixing the palladium and gold on the support as water insoluble compounds by contacting the salt-impr egnated support with a reactive solution in two separate fixing stages wherein the treated support is dried and allowed to s tand prior to treatment in the second stage to precipitate the insoluble compounds on the support and reducing the insoluble co mpounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to r educed selectivity to CO2 during the vinyl acetate forming reaction.
