Abstract: SUBMERSIBLE VACUUM CLEANER                        ABSTRACT         The invention provides a self-contained cordless electric pool and spa vacuum cleaner which is easily maneuverable over both flat and highly contoured underwater surfaces.  A pump impeller, powered by an electric motor, is used to draw water through a compact filter cartridge.  The efficiency of the filter cartridge allows for the use of a small motor and small battery which, in turn, result in the small size of the vacuum cleaner.  All electrical components are enclosed in a watertight chamber so as to allow the entire cleaner to be submerged under water.

Granted: 1996-06-11
Abstract: Resin stream shut-off control apparatus for use in a multi-layer extrusion die head for continuously forming a multi-layer plastic resin parison tube suitable for blow-molding and having alternating sections X, comprised of layers formed from all the resins introduced into the die head, which sections are encaptured by one or more blow mold(s) for forming blow-molded articles, especially containers, and sections Y having portions devoid of selected one or more of the layers (which would usually be formed from the relatively more expensive of the resins) which sections Y do not comprise the final article (container) and therefore become flash or scrap.  The resin stream shut-off or control apparatus includes an assembly which, in preferred usages, intermittently selectively shuts off flow of the selected one or more resin streams and thereby prevents them from forming layers in parison sections Y, and which is preferably comprised of movable means, and a die element which define a resin channel orifice and which cooperate in the die head preferably at or adjacent the orifice to prevent flow of the selected stream(s) through the orifice.

Title: Power adaptor
Inventor: CHARLES JOSEPH T
IPC: H02M7/10
Filed: 1991-05-10
Granted: 2000-04-11
Abstract: An adapter for connecting an electrical load which is mobile, such as the electrical system of a pleasure craft, to a stationary power source, such as the electrical pedestal at a marina. In its preferred embodiment, the adapter serves to connect a higher voltage load (such as a 240 volt electrical load of a pleasure craft) to a pair of conventional 120 volt sources, Input cables include a pair of connectors for independent connection to sources on the pedestal. Isolation means within the adapter serves to isolate the input connectors from each other during the connection operation such that a user holding one connector while connecting the other will not receive an electrical shock. Sensing means within the adapter determines that the sources are in the proper relationship to sum to the level required by the mobile load. When the sensing means determines that the sources are connected and in the proper relationship, contacts are closed connecting the summed inputs to the output for driving the load.

Title: Echo canceller using impulse response estimating method
Inventor: MARUYAMA YUISUKE
IPC: H03H21/00
Filed: 1991-09-11
Granted: 1996-10-01
Abstract: An echo canceller uses a Finite-Impulse-Response (FIR) filter to remove an echo from a transmission input signal, the echo resulting from a reflection of a received signal through an echo path.  An echo-cancelled signal is thereby output.  The echo canceller includes impulse response estimating means for estimating the impulse response of the echo path at a time t from the received signal, the echo-cancelled signal, and the estimated  impulse response signal.   The estimated  impulse response is output as the estimated impulse response signal. An echo signal estimating means determines a predicted signal of the echo signal from the estimated impulse response signal and the received signal, and outputs the predicted signal as an estimated echo signal.  Subtractor means subtracts the estimated echo signal from the transmission signal to produce the echo cancelled signal, and the impulse response estimating means estimates the impulse response of the echo path by using the received signal and the echo cancelled signal at the time t, and the received signal and the echo cancelled signal at a time (t-M) (M being a natural number).
