Title: Process and device for coating disc-shaped data storage media
Inventor: WEBER KLAUS
IPC: B05B15/72
Filed: 1997-03-26
Abstract: In a process for coating disc-shaped data storage media (8) with a coating agent which is applied to the storage medium (8) via a coating nozzle (1) in its inner region and spread thereover by the centrifugal force arising when the storage medium (8) is rotated, it is possible to achieve a high coating rate reliably and with shorter coating times and with less complex manufacturing and maintenance if the coating nozzle (1) is moved quickly in an initial movement cycle close to the coating agent application point (12) and in a second movement cycle (11) slowly to the point of application (12). A device for implementing the process is given.

Title: Materiaux pour enregistrement d'images
Inventor: VISKI PETER
IPC: G03C8/10
Filed: 1997-09-17
Abstract: L'invention concerne des matériaux permettant d'enregistrer des images, qui comprennent un composé générateur de colorants d'image contenant un nouveau colorant azo cyano naphtol avec un fragment 3-aminobenzo-isothiazole. Le composé générateur de colorants d'image contient un fragment de contrôle de la diffusion, tel qu'un groupe révélateur hydroquinonyle, un de ses précurseurs ou un fragment thiazolidine, et il peut être diffusible ou non diffusible en fonction du fragment de contrôle de la diffusion. Les matériaux de l'invention, notamment ceux contenant des révélateurs à fort potentiel, tels que l'aminoréductone, donnent un chromophore cyan suffisant pour diffuser jusqu'à la couche réceptrice d'image, ce qui donne une photographie acceptable et ne provoque pas de diminution notable du fragment 3-aminobenzo-isothiazole du nouveau composé azo cyano naphtol.

Filed: 1997-03-21
Abstract: A remote data collection system, which may be used in a vehicle such as an aircraft or a ground vehicle, includes a directional sensor, such as one or more cameras, for sensing a characteristic of interest and providing sensor data. The system further includes a global positioning system (GPS) receiver for providing GPS data representative of the position of the sensor, an inertial measurement unit (IMU) for providing IMU data representative of the attitude of the sensor, a processing unit and a storage unit. The processing unit determines geographic data referenced to the sensor data in response to the GPS data and the IMU data. The processing unit may utilize an error model to determine IMU errors which may be used in determining the geographic data with high accuracy. The sensor data and the geographic data are stored in the data storage unit for subsequent use. The system may include a stabilized platform on which the sensor and the IMU are mounted. The stabilized platform is rotated about at least one axis of rotation to control the sensing direction of the sensor as the vehicle moves.

Title: Fluid flow valves and cooking machine control systems utilizing such valves
Inventor: SPEAKMAN THOMAS S
IPC: F24C3/00
Filed: 1998-11-03
Abstract: A cooking machine control system for controlling the consumption of fuel by gas cooking machines, and gas flow valves usable in such cooking machine control systems. The cooking machine control system maintains the cooking surface of the cooking machine at an appropriate standby temperature when no food is being cooked, brings the cooking surface to an appropriate temperature to cook the food, and then returns the cooking surface to the standby gas flow rate. The system can be returned to the standby gas flow rate either after the cooking gas flow rate has been provided for sufficient time for the food to have cooked or after the temperature of the food has reached the desired level. With the cooking machine control system in the standby mode, when food is to be cooked a switch is actuated, applying a start signal to cause a valve to open the cooking flow rate path to cook the food, following which the valve returns the system to the standby mode. In another embodiment, the cooking machine control system includes a first gas pipe which provides gas to each burner of the cooking machine at the standby gas flow rate and a second gas pipe which in the standby mode is closed by a valve. When food is to be cooked, the start signal opens the valve to provide gas to each burner at a rate sufficient to bring the cooking surface to the appropriate cooking temperature.

Title: Dynamic selection of interworking functions in a communication system
Inventor: IYENGAR VENKATESH GOVINDARAJAN
IPC: H04M3/00
Filed: 1999-01-28
Abstract: The invention provides techniques for selecting, on a dynamic basis, an interworking function (IWF) that can modify a communication protocol to a particular format required by bridged terminal equipment in a communication system. The IWF can be selected to ensure compatibility between transmission bandwidth, coding and other format parameters of a call and the corresponding parameters of its destination terminal in the system. An IWF in accordance with the invention may be utilized to allow a user to bind to different terminals having different capabilities over the duration of a given call. An IWF in accordance with the invention may also be used to insert additional data, retrieved from a database of the switch, into a reverse portion of the call directed from the destination terminal to the source terminal. The invention can thus be used to ensure that the established bandwidth between the destination terminal and the source terminal is substantially bidirectionally symmetric.

Title: Low impedance grid-anode interaction region for an inductive output amplifier
Inventor: SYMONS ROBERT SPENCER
IPC: H01J25/04
Filed: 1999-03-24
Abstract: A linear beam amplification device includes an axially centered electron emitting cathode and an anode spaced therefrom. The cathode provides an electron beam in response to a relatively high voltage potential defined between the cathode and the anode. A control grid is spaced between the cathode and anode for modulating the electron beam in accordance with an input signal. A signal input assembly of the linear beam amplification device comprises an axial input cavity into which the input signal is inductively coupled. The grid-cathode region is electrically connected to the input cavity.  A low impedance grid-anode cavity is disposed coaxially with the input cavity and is in electrical communication with an interaction region defined between the grid and the anode. The low impedance of the grid-anode cavity is provided by constructing the cavity of a material having a relatively high surface resistivity, such as iron. The high surface resistivity tends to reduce the Q (quality factor) of the grid-anode cavity, which also reduces the impedance of the grid-anode cavity. Alternatively, the grid-anode cavity may be tuned to define a transmission line having an electrical length approximately equal to n.lambda./4, where .lambda. is the wavelength of the input RF signal, and n is an even integer.

Filed: 1997-12-12
Abstract: L'invention concerne des procédés servant à changer les mécanismes d'action métabolique de micro-organismes, en présence d'une certaine source de carbone, ainsi que des utilisations de tels changements. L'invention concerne également des micro-organismes et des utilisations de tels changements, de même que des micro-organismes produits à l'aide de ces procédés. Dans un mode de réalisation préféré de l'invention, on utilise des nouvelles souches de levure à rendements en biomasse améliorés. On décrit donc un procédé d'obtention de ces levures ainsi que de potentielles applications de celles-ci. On améliore le rendement en biomasse en introduisant, dans une levure, une construction d'ADN modifiant l'expression d'un gène codant pour une protéine régulant la transcription d'un certain nombre de gènes réprimés par glucose. Comme ces levures sont moins sensibles à la répression par le glucose, on obtient un accroissement de la capacité respiratoire, une diminution de la production d'éthanol et une conversion accrue du sucre en biomasse.
