Title: Skin for automotive air bag cover panel formed by casting different plastic materials
Inventor: RHEINLANDER FRED
IPC: B60R21/2165
Filed: 1998-06-19
Abstract: A skin (12) for an automotive interior panel has a main body portion (20) for covering most of the panel and an air bag cover portion (22) for covering the panel portion that the air bag deploys through. Casting a first plastic material against a first portion of a heated mold surface forms the main body skin portion (20). Casting or spraying a plastic material against a second portion of the heated mold surface forms the air bag cover skin portion (22).  The mold surface portions may be confined from one another by a partition or by masking one portion while casting against the other. The main body and air bag cover skin portions include adjacent edges (38, 40) that extend along the air bag cover portion periphery. The two skin portions are joined together along their adjacent edges while still on the heated mold. An air bag deployment tear seam is formed by first casting a tear seam (30) gap in the cover portion then spraying or casting a relatively weaker material into the gap. Alternatively, a heated engraving tool or laser may be used to form a tear seam groove in the back side of the air bag cover skin portion, or a cutter device may open the cover upon air bag deployment.

IPC: B01D21/00
Filed: 2000-03-07
Abstract: Disclosed are inventions to improved apparatus and methods of separation and control of drilling fluids in under-balanced drilling. Separation is conducted at reduced pressures to improve gas separation efficiencies. Preferably, separation is performed in multiple steps of pressure drops to eliminate foaming and to enhance gas removal. Solids are removed from the shaped bottom of a separation pressure chamber by creating a slurry and fluidizing and agitating the slurry to enhance solids removal.

Title: Method and apparatus for reducing start-up delay in data packet-based network streaming applications
Inventor: SCHULLER GERALD DIETRICH THOMA
IPC: H04L49/9023
Filed: 2000-03-16
Abstract: A method and apparatus which reduces the start-up delay that may occur when switching programs in audio and/or video streaming applications while maintaining high quality steady-state performance thereof. A program source (e.g., an audio and/or video data stream) is encoded and transmitted as two or more separate bit streams (e.g., sequences of data packets), the transmission of one of these bit streams being delayed by a given amount of time relative to the transmission of the other bit stream(s). At the receiving end of the transmission channel, the two or more bit streams are buffered by receive buffers having different sizes (thereby resulting in different time delays when the contents thereof are decoded), wherein the time delay difference corresponds (inversely) to the relative delay times prior to transmission. Advantageously, either a multiple descriptive source coding scheme or an embedded coding scheme may be employed, in which at least one of the individual bit streams is sufficient to obtain a satisfactory decoded signal, but wherein the addition of the other bit stream(s) will improve the quality of the decoded signal.   Alternatively, the data streams may comprise multiple encodings of the program source having different bit rates, wherein the lower bit rate encodings are transmitted with the correspondingly larger delays.

Abstract: Un parquet composite renforcé de fibres est conçu pour les trains routiers qui évoluent dans des conditions défavorables, pour le dessus en raison de la lourdeur des charges transportées et pour le dessous en raison de l'eau qui y est projetée lorsqu'il pleut. Le parquet composite comprend du bois lamellé collé sur chant, qui repose sur une mince couche de plastique renforcé de fibres. La face supérieure du parquet composite est identique à celle d'un parquet de bois lamellé classique. La sous-couche de plastique renforcé de fibres se compose de fibres de verre et/ou de fibres de carbone incrustées dans une résine polymérique, telle que de la résine époxyde, phénolique, ester vinylique, polypropylénique ou polyamédique. Le renforcement de fibres est conçu pour rehausser les propriétés mécaniques du parquet dans les directions longitudinale et transversale du plancher. Le plastique renforcé de fibres accroît la résistance à la fatigue du parquet composite et empêche l'eau de pénétrer dans la remorque entre les lames du parquet.

IPC: H01Q21/20
Filed: 1999-09-27
Abstract: An object of the present invention is to provide an antenna feeding circuit, which requires no balance-unbalance converter and has a simplified structure.      The object is attained, by an antenna feeding circuit, according to the present invention, in which micro-strips lines are constituted from one or more pair(s) of band conductors (5a, 5b) disposed on the outer surface of the cylindrical body (1) and an inner conductor (6) disposed on the whole of the inner surface of the cylindrical body (1). A 180 degree distributor (2) supplies electric power to the band conductors (5a, 5b) so that the phase difference between the currents in,the band conductors (5a, 5b) is 180 degrees, and due to this, inutile current generated in accordance with the connection of the balance and unbalance lines.      Inutile current induced in the inner surface of the inner conductor can be cancelled out, because the inner conductor 6 is disposed on the whole of the inner surface of the cylindrical body (1).

Title: Wireless telemetry methods and systems for communicating with or controlling intelligent devices
Inventor: WARFEL KARL B
IPC: H04M11/00
Filed: 1999-03-24
Abstract: Methods and apparatus are disclosed for remotely monitoring and controlling via a wireless network various devices deployed in homes and businesses. The present invention allows for monitoring and control of various gateways distributed to remotely located facilities to be monitored and the devices coupled to those gateways to be controlled via a wireless communications network. Preferably, the network is a GSM network adapted to provide short messaging services or any type of wireless network adapted to operate a General Packet Radio System for delivering data over the network. Messages are packaged at each gateway for delivery via the network to a destination terminal, whether a fixed terminal or a mobile station. Likewise, customers may forward data and commands to a particular gateway either from a mobile station or by accessing a fixed terminal, such as through an Internet connection. Transporting messages or commands via the short messaging service of the GSM network or via the GPRS protocol avoids the prohibitive cost of setting up a call for each message and avoids the significant capital costs needed to set up a separate communication network for data delivery.

Title: Machine for enrobing tablets with gelatin
Inventor: PERRONE ALDO
IPC: A61J3/06
Filed: 1999-04-13
Abstract: An apparatus for enrobing tablets in a gelatin layer includes a pair of die assemblies with each assembly including a rotatable, cylindrical die support and a series of die blocks mounted on this support for movement along a circular path. Each block has recesses formed in a top surface thereof and each recess of one assembly cooperates with a similar recess in the other assembly to form a cavity at a nip formed by the two assemblies. Each cavity is dimensioned to receive loosely therein one of the tablets. Two casting drums deliver gelatin strips to the die assemblies and each strip is pulled by one assembly into the nip. A time tablet dispensing mechanism is used to dispense tablets onto one of the strips at a feeding location. The preferred die blocks are made of hard plastics material. The tablet dispensing mechanism employs vacuum applying members operatively connected to a vacuum source and air cylinder transfer mechanisms for moving these members from a tablet pick-up position to the feeding location.
