Title: Process for Converting Lead and Lead Oxides to Barium Metaplumbate
Inventor: FIORINO MARY E
IPC: H01M4/68
Filed: 1995-01-18
Abstract: The present invention provides improved processes for forming anti-corrosion layers, particularly barium metaplumbate, on lead, lead alloy-, and lead oxide-containing substrates. The processes of the invention are used to form corrosion-resistant current collectors which are assembled into lead-acid batteries. The inventive methods used to form barium metaplumbate employ a salt solution which includes a barium compound and a solvent salt. In a first embodiment, a substrate material having at least a surface comprising elemental lead reacts with a salt solution to form barium metaplumbate. The salt solution includes a barium compound and an oxidizing agent. The solvent salt or barium compound may themselves be oxidizing agents, or an additional oxidant may be added to the solution. The molten salt solution is applied to the substrate in any known manner such as dipping, spraying, and brushing. Advantageously, a lead or lead alloy-containing substrate is dipped into a molten salt solution heated to a temperature at which a portion of the lead-containing substrate is directly converted to bariummetaplumbate. In a further embodiment of the invention, barium metaplumbate is formed on a lead oxide-containing substrate. This process employs a salt solution comprising a barium compound and a solvent salt to convert lead oxide to barium metaplumbate.

Title: Electronic component interface
Inventor: TAYLOR BILLY P
IPC: H04M1/27475
Filed: 1995-09-05
Abstract: A method for controlling flow, through a computer hardware resource, of information to and from computer applications.  When a flow of information is initiated from one of the applications, a determination is made whether the resource is being accessed by another one of the applications and, if so, the flow of information from the first application is delayed.  If not, then the flow of information is enabled.  When a flow of information is initiated toward the applications, a determination is made to which one of the applications the information is flowing, and the flow is directed to that one application.  A graphical interface associates, in the mind of a user, a computer hardware resource with a corresponding real office device, the computer resource enabling the computer to function like the consumer device.  The graphical interface includes a surrealistic image having physical features which represent functional components of the resource, the physical features of the image resembling corresponding features of the office device; and an animation routine which causes the image to change when the user selects one of the features of the image, thereby invoking the corresponding functional component of the resource, the change occurring in a manner which resembles changes to the office device when the corresponding feature of the office device is invoked.

Abstract: Un conduit d'air (5) et un canal de dérivation (6) auquel est associé un élément d'obturation (7) sont prévus dans le corps (2) de la soupape (1). Une conduite pulsée (8) divisée dans la zone de la soupape (1) permet d'assurer la jonction entre le raccord (3) de la soupape (1) et un pulsateur, et le raccord (4) et la chambre pulsée d'un récipient trayeur. L'élément d'obturation (7) comporte un corps de soupape (9) sollicité par un ressort de pression (10) dans le sens d'ouverture. En phase d'évacuation de la chambre pulsée, les sections du conduit d'air (5) et du canal de dérivation (6) permettent à l'air de s'écouler. En phase de ventilation, le canal de dérivation (6) est fermé par l'élément d'obturation (7), de manière à ce que le conduit d'air (5) n'assure que l'écoulement de l'air. En phase d'évacuation, la section transversale à disposition pour l'écoulement de l'air est par conséquent sensiblement plus grande qu'en phase de ventilation, ce qui permet une suppression rapide de la pression en phase d'évacuation et une remontée plus lente de la pression en phase de ventilation dans la chambre pulsée du récipient trayeur. L'action massante exercée sur les trayons ne les altère de ce fait en aucun cas.

Abstract: The present invention provides a method (100) and device (200) for allocating bits to video pictures in a video compression system. A sequence of video frames or pictures is received (102), and the number of bits used to compress a previously encoded frame and a signal-to-noise ratio for the immediately previously encoded video frame are determined (104). Rate distortion model parameters are updated (106). Then, first (108), second (110), and third (112) deviations are determined. Finally, the bit allocation for the frame is determined based on the first number of bits used to compress a previously encoded frame the first deviation, the second deviation, and the third deviation (114).
