    摘要： Shifter circuits comprise a matched translation stack comprising at least first and second stacks each of which comprising multiple transistors. The matched translation stack is configured to provide a primary logic level shift between a voltage level away from which a shift is desired (VddL) and a voltage level to which the shift is desired (VddH). One or more high voltage buffer stages are provided, at least one of which being connected with and biased by the matched translation stack. At least one high voltage buffer stage comprises multiple transistors arranged in a transistor stack that is biased by the first stack of the matched translation stack, and is connected to receive an input supplied by the second stack of the matched translation stack. The high voltage buffer stage also comprises an inverter that drives an output stage which is also driven by a low voltage buffer stage.

    摘要： Process for the manufacture of hydrated lead oxides in the bivalent state characterized by the step of (1) reacting metallic lead with acetic acid (e.g. ammonium acetate, 5%-30% solution) at a temperature up to 200.degree. C. (e.g. 50.degree.-200.degree. C.) under an atmosphere of an oxygen containing gas (e.g. oxygen) of between 1 and 10 atmospheres absolute pressure to form lead acetate, then (2) reacting the lead acetate with a source of ammonium ion (e.g. ammonia) under an absolute pressure between 1 and 5 atmospheres at a temperature up to 100.degree. C. (e.g. 60.degree.-90.degree. C.) to precipitate lead oxides and, optionally, to produce tri- and tetra- basic lead sulphates, by (3) adding to the lead oxides so precipitated sulphuric acid in the stoichliometric amount to produce tri- or tetra- basic lead sulphate, then (4) separating and drying the tri- or tetra- basic lead sulphate so formed.

    摘要： A fastener for fastening pipes or electrical conduit can be installed with the optional use of nails or screws. The fastener includes sharp teeth or spikes which can be hammered into an external surface, such as wood or masonry. The teeth or spikes are positioned, oriented, and otherwise configured to best suit the intended application. Installation can be accomplished using only the fastener itself and force exceeding a minimal threshold.

    摘要： A method enabling a service at a communication network node and a network node adapted to execute the method is provided, wherein a first request, requesting for one or more operations to be associated with a symbol, is received from a first user. The request comprises an instruction, identifying one or more operations. The request triggers the generating of a unique symbol identity, and the creation of a symbol record, associated with the symbol identity, wherein the symbol record, linking the symbol identity to the one or more operations. At the node the symbol identity is also associated with the generated symbol, which is created by a symbol server and forwarded to the first user. Once the symbol has been received by the node in a second request, the symbol identity corresponding to the symbol is retrieved from the symbol server, and the service is enabled by executing the one or more operations according to the symbol record identified by the symbol identity.
