Filed: 1991-03-11
Granted: 1996-05-28
Abstract: A process and apparatus for reducing sludges, especially those sludges containing heavy metals and generated in elecro-plating, to a solid state where the toxic constituents of the waste are prevented from leaching. The process involves mixing a metal-lic soap with the sludge and then using low-temperature induction heating to form coacervate bonds that encapsulate the toxic waste particles in a pumice-like matrix. The process comprises the utili-zation of an apparatus (1) which allows a small amount of metal-lic soap to be thoroughly mixed in a mixer (2) throughout the sludge and formed into a contin-uous ribbon and carried on a conveyor (7). The resulting putty-like waste is then fed into a series of microwave drying ovens and evacuation chambers (8a, 8b and 9). After the drying and de-water-ing sequences, the apparatus ex-trudes a pumice-like solid suitable for disposal in accordance with EPA regulations.

Title: Device for the swiveling movement of a sheet, in particular in refrigeration counters or merchandise counters
Inventor: STENEMANN BRUNO
IPC: A47F3/00
Filed: 1995-01-27
Granted: 2005-04-05
Abstract: The invention is directed to a device for the swiveling movement of a sheet. A stationary bearing part supports an articulated part in a swivelable manner.  The articulated part supports the sheet and is movable about a substantially horizontal swivel axis. The sheet is accordingly movable between a lowered position and a raised position, the direction of this movement being determined by a vertical swiveling plane. Energy accumulators, e.g., pneumatic springs, serve as auxiliary lifting means for raising the sheet.  These energy accumulators have two connection ends which are loaded in opposite directions and determine the effective direction of force of the energy accumulator. For the purpose of an advantageous arrangement of the device which economizes on space, it is proposed that the energy accumulator be arranged with its effective direction of force substantially transverse to the swiveling plane of the sheet. The two connection ends of the energy accumulator are constructed as three-dimensionally acting rolling joints.

Granted: 2002-04-30
Abstract: A system for handling organic waste at a food-handling facility includes a mill that reduces the volume of the waste and a below-ground storage tank that receives the milled waste. A ventilation line and an air flow producer draw air from the storage tank, placing the tank under negative pressure and preventing noxious odors from escaping into the facility. A rigid suction line extends from the interior of the storage tank to points external to the tank and the facility itself. A suction truck periodically removes the waste stored in the tank, applying suction to the suction line to draw the stored waste into a portable tank aboard the truck. The suction truck transports the waste to a disposal site where the well-divided waste may be expelled onto and incorporated by tilling into soil for decomposition by soil organisms.
Patent CA-2153723-C (CA)
Inventor: SPENCER CHARLES P
IPC: B61F5/52
Filed: 1995-07-12
Granted: 1998-02-03
Abstract: A lightweight, cast steel railcar truck sideframe is the result of matching stress levels within each of the sideframe components with an amount of metallic mass necessary to maintain structural integrity during railcar loading. Areas on each component which were found to be low stress accumulation areas have removed mass from them, reducing sideframe weight. The removal of mass is accomplished by adding lightener holes to and/or reducing thickness of the particular component. Areas on each component found to be high stress areas have added mass in order to strengthen the sideframe. Areas with reduced mass far exceed those increased. The lightener holes are uniquely used in the casting mold such that only nine cores are needed when casting the entire sideframe. By using only a total of nine cores instead of twenty-eight, substantial manhour and production costs savings are realized. The nine core mold also improves internal and external casting quality through the stabilization of core geometry, elimination of seam lines and stress riser locations, which means that there will be far less of a chance for defects to occur.

Abstract: The present invention proposes an optical wavelength division multiplexer device which has low through loss and low reflection loss, and also has high isolation. A filter member is made up from a filter base board upon which is formed a wavelength division filter 5, and is disposed so as to intersect an input and output optical waveguide 3 of rectilinear form part-way along it at an intersection angle .alpha.. When light which includes light of two different wavelengths .lambda.1 and .lambda.2 is incident through an incident light side of the input and output optical waveguide 3, the light of wavelength .lambda.2 passes through the wavelength division filter 5 and is emitted through an emitted light side, while the light of wavelength .lambda.1 is reflected by the wavelength division filter 5 in a direction separated from the input and output optical waveguide 3. A reflected light reception waveguide 1 is formed as rectilinear and is arranged in this reflection direction so as to receive the reflected light, with a gap being left between this reflected light reception waveguide 1 and the input and output optical waveguide 3, and the reflected light of wavelength .lambda.1 is received into a reflected light reception end thereof and is emitted from a received light after end portion thereof. By providing this gap between the input and output optical waveguide 3 and the reflected light reception waveguide 1, increase of loss due to mutual action between the incident light and the reflected light is restrained.
