Title: Drainable louver
Inventor: OLSEN ROBERT W
IPC: F24F13/08
Filed: 1991-12-13
Abstract: Drainable Louver Abstract A drainable louver comprises a frame composed of a sill, a head and a pair of side members forming a rec-tangular opening and a multiplicity of vertically spaced-apart louver blades extending across the opening between the side members and fastened to the side mem-bers.  Each of the blades has a drainage trough extend-ing along its lower front edge and terminating at each end adjacent a corresponding side member of the frame, and each of the side frame members has a base wall portion engaging the corresponding ends of the blades throughout their lateral extent.  Each side member has a front flange portion defining with a front part of the base wall portion a vertical drainage channel located laterally of the corresponding ends of the drainage troughs of the louver blades on the side of the base wall portion opposite from the blade.  The drainage channel of each side member has an opening at the front face of the frame throughout its vertical extent, and the front part of the base wall portion has an opening in register with the corresponding end of the drainage trough of each louver blade so that water can flow from the drainage trough of each blade into the drainage channel.

Title: Electric current measurement apparatus for a solid state motor controller
Inventor: UNSWORTH PETER J
IPC: H02P27/02
Filed: 1992-05-07
Abstract: An electric induction motor is coupled to a source of alternating current by a thyristor switch.  A control circuit triggers the thyristor switch to create conductive and non-conductive states during each cycle of the alternating current.  A circuit senses the voltage across the thyristor switch during a non-conductive state.  From that sensed voltage and known characteristics of the motor being controlled, the control circuit derives a measurement of the current flowing through the motor in the conductive state of the thyristor switch.  One of two different derivation techniques is used depending upon the length of the non-conductive state.  The control circuit includes a means for calibrating the derivation of the current measurement for a specific motor.

Filed: 1992-06-25
Abstract: Dynamoelectric machines are disclosed that are characterized by lengthened ground potential leakage current paths, desirable mechanical conformations, mechanical integrity when subjected to expected centrifugal forces, and ease of manufacture. One process involves establishing an extended or elongated path for commutator leakage currents with a path extending structure, establishing a cantilevered insulation skirt about the in-board or armature coil end of a conumutator, and securely fastening such skirt to the commutator. The material utilized in making the skirt is one: that has electrical properties that permit it to withstand leakage currents without tracking; that for practical purposes is non-burnable, so as to resist flashovers or sparking; and that has the ability to withstand elevated temperatures that are encountered within dynamoelectric machine. The skirt is provided with openings therein and sandwiched between two glass based bands that adhere to another through the openings and thus lock the skirt in place on the commutator body.

Title: Sludge treatment process
Inventor: GAYMAN DANNY
IPC: F26B5/04
Filed: 1991-03-11
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.

Abstract: Internal and external magnetic screens made of magnetic permeable material are added between the discharge chamber and the internal and external sources of magnetic field, respectively.  A longitudinal gap is maintained between the screens and their respective internal and external poles, that does not exceed half the distance between the internal and external poles.  The exit end part of the internal magnetic screen is placed closer to the middle point of the accelerating channel than the internal pole.  The walls of the exit end part of the discharge chamber are constructed with an increased thickness, and extend beyond the planes that the poles lay.  The magnetic screens can be located with a gap relative to the magnetic path if connected by a bridge between the screens.         The discharge chamber, the anode, and the magnetic system are symmetrically designed relative to two mutually perpendicular longitudinal planes.  Thus, the external pole and the external screen are made into four symmetrical parts relative to the planes; and the external sources of the magnetic field are made with four magnetic coils, each coil connected with one part of the external pole.  The discharge chamber is connected to the external pole with a holder at its front part.  The holder, with the exception of the locations of attachment, is situated with a gap relative to the discharge chamber and the external pole.
