Title: Telephone set with background noise suppression function
Inventor: KUBO MASATO
IPC: H04M1/19
Filed: 1994-12-21
Granted: 1998-12-22
Abstract: A telephone set is provided with a first microphone at the position close to a speaker and a signal including remaining noise is outputted from the first microphone.          Background noise is outputted from a second microphone.          A noise elimination circuit estimates background noise reaching the ear of a receiver based on the background noise signal, the signal including the remaining noise, and a received voice signal from a transmitter.  Also, the noise elimination circuit subtracts the estimated background noise from the received voice signal to supply the resultant signal to the speaker.

Title: Air conditioning device
Inventor: KAWASHIMA NOBUHIRO
IPC: H02M7/5387
Filed: 1995-06-30
Granted: 1999-10-05
Abstract: An air conditioning device is arranged such that an output voltage from a commercial power source is converted into a direct current by a rectifying circuit and a smoothing condenser, and thereafter, it is further converted into an AC voltage having a variable frequency by an inverter under the control of a microcomputer, thereby supplying it to a power compressor. Between the rectifying circuit and the smoothing condenser, provided is an active filter for shaping an input current to be an approximate sine wave almost in phase with an input voltage by switching a power transistor. The switching control section and the microcomputer for controlling the switching are activated independently by separately provided power sources. The switching control section supplies a high level signal when the active filter is a normal condition, while supplies a low level signal when the active filter is abnormal. A circuit which generates a low level signal when the power supply to the switching control section is shut off is provided. This enables the microcomputer to determine the occurrence of abnormality in the active filter or the switching control section even when the power supply is shut off.

Title: Filter press for filtering suspensions, especially sewage sludge
Inventor: PONOMARENKO VIKTOR
IPC: B01D25/127
Filed: 1995-12-19
Granted: 2003-02-11
Abstract: A filter press for the filtration of suspensions has a frame, a support plate, a pressure plate mounted in the frame and a set of vertically arranged filter plates between the support plate and the pressure plate. The filter plate is provided with a filter fabric on the side that removes the liquid and collects the solids. The filter fabric runs over two rollers that are so positioned relative to each other and relative to the fabric that an S-configuration for the removal of filter cake is imposed on the filter fabric.      A pressure application device presses the filter plates together. Spray nozzles for cleaning the filter fabric are combined with the rollers for the removal of the filter cake. Two such rollers are provided for each filter fabric of the respective filter plate and each filter fabric is of the single layer kind to reduce filter fabric consumption.      The single layer fabric also reduces the filtering resistance, thereby increasing the capacity of the filter press. The lower and upper edges of the filter fabric are secured to the respective edges of the filter plate, and the rollers for the removal of the filter cake are moved up and down by a lifter.

Granted: 1999-10-12
Abstract: Une pompe volumétrique (50) comprend une soupape de sûreté. Cette dernière comporte un siège de soupape (61), un pointeau (62) à l'intérieur du siège de soupape, un ressort (63) poussant en force le pointeau à l'intérieur du siège de soupape, une vis régulatrice (65) poussant en force le ressort contre le pointeau et un élément d'espacement (64) pour fixer la vis régulatrice au carter de la pompe volumétrique. Le siège de soupape est vissé dans le passage de la soupape de sûreté, ce qui supprime les problèmes d'érosion dans ce passage. Le siège de soupape peut être en plastique, en caoutchouc dur , ou en un matériau métallique et peut comprendre une garniture caoutchoutée fixée à une extrémité du siège de soupape. Lorsque ce dernier est érodé à un point tel qu'il ne constitue plus un siège suffisant pour le pointeau, il est retiré de l'intérieur du passage de la soupape de sûreté et remplacé par un siège de soupape similaire. La protection contre l'érosion du passage de la soupape de sûreté assurée par l'utilisation d'un siège de soupape peu onéreux, amovible et jetable permet d'éviter les opérations coûteuses de changement ou d'usinage du carter de la pompe volumétrique.

Abstract: An object of the present invention is to utilize the capabilities of currently available intelligent networks, such as the A-I-NetTM or compatible networks, to provide automatic forwarding of calls to enhanced telecommunications service platforms across network boundaries while preserving subscriber identity.  In accordance with the present invention, the values of defined parameters that are maintained with a call according to established network protocols and passed between networks during call processing are controlled in an atypical way so that, using these controlled values, the subscriber identification information reaches the platform where the enhanced service is implemented in a network different than that of the service subscriber.  An alternative embodiment of the invention provides a way for enhanced telecommunications services platforms to identify both the subscriber and the calling party when calls are automatically forwarded to the platform across network boundaries.
