Granted: 1999-11-16
Abstract: A method and apparatus for separating heterogenous mixtures of at least two components, including immiscible liquid/liquid mixtures or solid/liquid mixtures. The apparatus allows pre-separation before the influent enters the separator proper. Solutions enter a channel (10) at the same end (6) of the tank that the effluent is removed, and undergo some separation as they flow along the length of the separator tank (50) to the end (2) opposite the effluent end, where they enter the tank proper. The solutions then continue to separate as they flow through the tank to the effluent removal means.

Title: Switching power supply for the operation of electric lamps
Inventor: LECHELER REINHARD
IPC: H05B41/282
Filed: 1995-05-17
Granted: 2003-11-25
Abstract: The invention concerns an interference-control circuit for switching power supplies suitable for use in the operation of both discharge and incandescent lamps. The interference-control circuit has at least one controlled auxiliary supply (ZW, F) plus a control circuit (TR1). The auxiliairy supply/supplies (ZW, F) generate controlled compensation signals which are inverted with respect to the interference signals caused by the fast switching transistors (T1, T2). The auxiliairy supply (ZW, F) is connected either parallel to the source of interference and capacitively to the environment or in series with the source of interference and galvanically in to the supply leads. In the first case, the auxiliairy s upply preferably includes, near the switch (T1, T2), a metal surface (F) whose pot ential variations are inverted with respect to those of the source of interference essentially round the junction point (M) between the switchi ng transistors (T1, T2) e g. by means of the transformer (TR1). In the second case, the auxiliairy supplies are preferably formed by two second ary coils of a transformer. The primary coil is controll ed by the potential changes in the source of interference and induces in the leads of the secondary coil an opposite phase common-mode compens ation signal. Optionally, the interference-suppression circuit can be designed as a closed control circuit, the common-mode interference c urrent in the leads being used as the regulating variable.

Abstract: Perforated sheet steel or wire mesh to which tungsten carbide grit is copper braze welded to provide a device which can be cut to a desired size and shaped into or used as a substrate for tools used for sanding, filing, grinding, deburring, deflashing, cutting, sawing, filing and the like. The sheet steel being perforated provides apertures or recesses wherein removed material can collect and/or pass through reducing the clogging of the grit and frequency of cleaning the working surface of the tool or device. The apertures also provide for the flow of air, cooling the device in certain applications. Tungsten carbide gritted wire mesh is particularly good in providing a surface which tends to renew itself due to grit adhering to the side of the wire strands but not such as to clog the holes.  Welding the grit to the wire mesh or cloth also causes the strands of the cloth to be welded together providing for a strong, yet flexible device or substrate.

Title: Speaker recognition device
Inventor: HATTORI HIROAKI
IPC: G10L17/06
Filed: 1998-01-22
Granted: 2001-11-27
Abstract: A speaker recognition device is designed to actualize speaker recognition which is capable of coping with an increase of enrolled speakers with a small amount of processing and to provide a high precision of speaker recognition regardless of a variety of disturbances. Herein, sound analysis is performed on input voice data of an input speaker to produce an input pattern representing sound characteristics. The device stores standard patterns (e.g., time series of sound parameters or HMM parameters) with regard to enrolled speakers in a form of a tree structure which is constructed by nodes mutually connected together from a root to leaves. Similarity calculations are performed in a direction from the root to the leaves of the tree structure to produce similarity scores between the input pattern and the standard patterns respectively. An order is determined for the calculated similarity scores from the highest to the lowest. In addition, a similarity score is calculated for a designated speaker who is specified by speaker information input to the device. If a place of the order set for the designated speaker belongs to a prescribed range of places of the order, the device makes a decision of acceptance that the input speaker coincides with the designated speaker. If not, the device makes a decision of rejection that the input speaker feigns to be the designated speaker.
