Granted: 2007-01-30
Abstract: Lead brass components for potable water distribution circuits (e.g., plumbing components made of CuZn39Pb3, containing 3 % Pb), also chronium plated ones, are subjected to a lead-selective surface etching to reduce, in operation, the release of Pb caused by Pb surface "smearing", resulting either from machining or molding; said elements are firstly contacted by an aqueous solution of an acid capable of forming soluble Pb salts, preferably a non-oxidizing solution, by simply dipping the components in the solution, e.g., a solution of 0.1 M sulfamic acid, at 20°-50° C for 10 to 50 minutes, and, subsequently, the elements are passivated by immersion into a strong base aqueous solution, e.g., a solution of 0.1 M NaOH at 20°-25° C, for approximately 10 minutes; in this manner, plumbing components made of a copper based alloy containing Pb are obtained, which components, after 15 days of test according to US NSF STD61 procedure, release Pb in an amount less than 0.025 µg for each ml of the internal volume of the component delimited by metallic walls remained in contact with water during the testing period.

Abstract: A power distribution unit for supplying temporary branch power has a 240-250 VAC input with input power line conductors L1 and L2, a neutral conductor N, and a ground conductor G. A supervisory circuit checks that the 240-250 VAC input is properly connected to the power distribution unit by requiring that the input voltage exceeds a supervisory circuit threshold voltage substantially greater than 120-125 volts. When that occurs, a contactor is enabled by the supervisory circuit to close first and second contacts therein to pass the 240-250 VAC on lines L1 and L2 therethrough to a 240-250 VAC ground fault interrupter protected circuit breaker outlet. A plurality of 120-125 VAC GFI module outlets are connected across either one of lines L1 and L2 at the output of the supervisory circuit and the neutral conductor N which bypasses the contactor. The supervisory circuit includes a diode bridge circuit connected across power line conductors L1 and L2 to convert a 240-250 VAC input to 240-250 VDC. A voltage threshold zener diode is connected in series with first and second relays across the 240-250 VDC, such that the zener diode ensures that the voltage required to operate the first and second relays is substantially greater than 120-125 VDC. The first relay operates contacts to activate the contactor, and the second relay operates contacts to bypass the neutral conductor N around the contactor.

Title: Tail-biting turbo-code encoder and associated decoder
Inventor: GUINAND PAUL
IPC: H03M13/03
Filed: 1999-06-01
Granted: 2008-03-25
Abstract: A method of creating tail-biting recursive systematic convolutional and turbo codes, and the associated encoders and decoders, are described herein.  According to the method, symbols from the set of data to be transmitted are used to preset the starting state of the encoder, and are replaced in a systematic set by an equivalent number of tail--biting symbols that force the ending state of the encoder to be the same as the starting state. The presetting of the starting state allows for simpler calculations in computing the tail-biting codewords, and allows a message to be transmitted with a reduced number of symbols. The reduction in the number of symbols used for overhead in this invention provides an increase in the data transmission rate.
