A method is provided for temporarily or permanently blocking the bore of a gas service pipe 5. In the method a resilient ball 6 is forced along the pipe 5 from the gas meter tap end of the pipe 5 by gas pressure, the ball 6 forming a force fit sufficient to resist any attempt to dislodge it by the pressure of gas in the pipe 5. The ball 6 is forced to a position where it is outside the gas consumer's premises 1.

A thruster for use in a spacecraft uses vaporized propellant in its combustion chamber (110). Normally two propellants are used of the kind used for main thrusters so that two vaporization chambers are needed. Pressure valves (108, 109) are controlled by electronic means (220) to maintain current pressure.

The water-insoluble monoazo dyestuffs, free from sulphonic acid and carboxylic acid groups, which are of the formula: ##STR1## wherein Y is hydrogen, lower alkyl, optionally substituted phenyl or nitro; Z is nitro, cyano, optionally substituted phenyl, optionally substituted lower alkoxycarbonyl or carbonamido; T is hydrogen, optionally substituted lower alkyl or optionally substituted lower alkoxy;W is an acylamino group of the formula: ##STR2## wherein X.sup.1 is hydrogen or lower alkyl, X.sup.2 is hydrogen or an optionally substituted hydrocarbon or heterocyclic radical, and A is a direct link or --0-- or ##STR3## and R.sup.1 and R.sup.2 each independently represent a hydrogen atom or an optionally substituted alkyl radical or R.sup.1 and R.sup.2 together form with the nitrogen atom N a 5- or 6-membered nitrogen-containing heterocyclic ring, a process for the manufacture of the said dyestuffs by diazotization and coupling, and the use of the said dyestuffs for coloring synthetic textile materials, in particular aromatic polyester textile materials which they color in violet to green shades possessing excellent fastness to light, to wet treatments and to dry heat treatments.

Systems, methods and devices for creating an effect using microwave energy to specified tissue are disclosed. A system for the application of microwave energy to a tissue includes a signal generator adapted to generate a microwave signal having predetermined characteristics, an applicator connected to the generator and adapted to apply microwave energy to tissue. The applicator includes one or more microwave antennas and a tissue interface, a vacuum source connected to the tissue interface, a cooling source connected to the tissue interface, and a controller adapted to control the signal generator, the vacuum source, and the coolant source. The tissue includes a first layer and a second layer, the second layer below the first layer. The controller is configured so that the system delivers energy such that a peak power loss density profile is created in the second layer.
摘要:
Described are methods and systems for combining programming content in a controlled synchronized manner. The systems and methods allow for centrally generated content to be modified using local content. The centrally generated content can include data that specifies what portions of the centrally generated content can be modified by the local content.
摘要:
A method of reducing a set of instructions for execution on a processor extracts information from a first instruction of the set of instructions. The method identifies unencoded space in one or more further instructions of the set of instructions and replaces the unencoded space of the one or more further instructions with the extracted information of the first instruction so as to form one or more amalgamated instructions. The method removes the first instruction from the set of instructions. A method of expanding a set of reduced instructions on a processor is also disclosed.

A method of encapsulating a long instruction in a set of short instructions for execution on a processor, the long instruction having k bits and each short instruction having l bits where l
摘要:
A method of executing an instruction set to select a set of registers, includes reading a first instruction of the instruction set; interpreting a first operand of the first instruction to represent a first register S to be selected; interpreting a second operand of the first instruction to represent a number N of registers to be selected; and selecting N consecutive registers starting at the first register S to form the set of registers.
摘要:
A method of executing an instruction set including a first instruction and a second instruction, includes reading the first instruction; determining whether the first instruction is an instruction which is integral with the second instruction; reading the second instruction; if the first instruction is integral with the second instruction, interpreting the operand field of the second instruction to indicate at least one value to be used in conjunction with at least one bit of the first instruction; and if the first instruction is not integral with the second instruction, interpreting the operand field of the second instruction to indicate an entry of a look-up table.

Swing seat adaptors are disclosed herein. According to an aspect, a swing seat adaptor includes an elongated seat element having a top portion and a bottom portion. Further, the swing seat adaptor includes first and second attachment members each having a first end attached to the top portion of the elongated seat. Each of the attachment members have an opposed second end configured for attachment to a chain of a swing seat. The swing seat adaptor includes a seat connection element attached to the bottom portion of the elongated seat element. The seat connection element is configured for attachment to a seat portion of a swing seat.
