Title: Counter-current contact process
Inventor: MURTAGH R
IPC: B01J8/10
Filed: 1979-12-04
Granted: 1982-04-30
Abstract: Liq.-solid countercurrent contact, e.g., for ion-exchange water treatment, is carried out in a perforated-plate column in which a stirrer (vane, paddle, etc) is positioned adjacent each plate to fluidize the solids and control the particle residence time.  The perforation diam. is 5-30mm and the plate free area 10-50%.  The stirrer-to-plate distance is 1/4 of the plate-to-plate distance, above or below the plate when the solids are fed into the top or the bottom of the column, resp.  The stirrers are mounted on a common shaft.

Title: Devices for separating the cleaning bodies of tube exchangers from the fluids which transport then
Inventor: BIZARD M ANDRE
IPC: F28G1/12
Filed: 1983-06-09
Granted: 1989-03-08
Abstract: The tubes of a heat exchanger are cleaned by circulating rubber balls, which have a diameter slightly greater than the tube bore, through the tubes with the circulating fluid.  After the balls have passed through the tubes and cleaned them, they are removed by a separator assembly.  The heat exchanger outlet duct has an inclined grid of parallel bars (4) with a spacing considerably less than the ball diameter.  The grid deflects the balls (2) to the side of the duct, where a funnel leads then to an outlet (3).  A transverse rib (9) creates a turbulence in the funnel which prevents the outlet from becoming blocked.

Granted: 1985-11-22
Abstract: Increasing the volume of water kept in storage and controlling the water level behind a dam, are problems which remain to be solved. Up to now, the method used to control the level of the water has been a soil bag or board, a lubber dam, a tenter-gate, or a syphon, which were used to increase the height of a reservoir. This apparatus could be used to control the water level of the dam automatically. The upper part of the floodgate(3) is moved from a changing full level(5) to a design planned level(15) for normal conditions. When the water overflows, the floodgate(3) can be moved to a flood level(7) position.

Abstract: Reactive stabilising compounds, able to stabilise organic polymers, contain in their molecule a sterically hindered amino group and a hydrolysable silyl function. 
<??>In stabilising organic polymers, said reactive stabilising compounds can be hydrolysed at the silyl function with the formation of silanol groups, which are made to interact in order to form complex resinous stabilising structures. These latter are added in stabilising quantities to the polymer to be stabilised. 
<??>According to one particular embodiment, the hydrolysis at the silyl function and the formation of the resinous structure take place spontaneously within the polymer to be stabilised. 
<??>According to a further embodiment, the reactive stabilising compound is added to the polymer after being stably supported on a solid support by reaction with an inorganic solid having surface hydroxyl groups. 
<??>According to a further embodiment, the reactive stabilising compound is made to interact with the polymer so that the stabilising compound becomes chemically bonded to the polymer chains. 
<??>In all cases, stabilised polymers are obtained containing the stabilising compound in a form which is not removable from the polymer. 
<??>The process for preparing the reactive stabilising compounds and for preparing the stabilised polymer compositions are also described.

Title: Method for encoding speech and apparatus
Inventor: KETCHUM RICHARD H
IPC: G10L25/93
Filed: 1988-06-25
Granted: 1998-04-02
Abstract: Apparatus (101-112) for encoding speech using an improved code excited linear predictive (CELP) encoder (106, 104) using a virtual searching technique (708-712) to improve performance during speech transitions such as from unvoiced to voiced regions of speech. The encoder compares candidate excitation vectors stored in a codebook with a target excitation vector representing a frame of speech to determine the candidate vector that best matches the target vector by repeating a first portion of each candidate vector into a second portion of each candidate vector. For increased performance, a stochastically excited linear predictive (SELP) encoder (105, 107) is used in series with the adaptive CELP encoder. The SELP encoder is responsive to the difference between the target vector and the best matched candidate vector to search its own overlapping codebook in a recursive manner to determine a candidate vector that provides the best match. Both of the best matched candidate vectors are used in speech synthesis.
