This invention provides multilayer polymeric films including a layer of nylon polymer having a Vicat A(DIN 53460) softening point of not more than 170.degree. C. and being substantially impermeable to styrene, and a layer of a weldable synthetic plastics composition bonded to the layer of the nylon polymer. Such films can be used to recondition pipes, for example sewer pipes. They have the advantage of being resistant to swelling by synthetic resin compositions, particularly styrene, used to impregnate a fibrous mat which is bonded to the film when used to recondition pipes. In addition, the films have shown resistance to puncturing.

A method and system for using XML for both a protocol layer and application data are described. The method comprises the steps of initiating a connection by a client to a server to form a session, responding by said server to said client indicating that said connection has been successfully completed, submitting a request by said client to said server for service, responding by said server to said client by providing said service and terminating the connection by said client. A session is maintained and a plurality of requests for service by a client and a server responds to those requests by providing the requested service or an error message. The session is maintained until all requests made by a client have been serviced and the requests made by a client may be either synchronous or asynchronous. The system comprises a client and a server coupled to said client by a communication link.

An operational amplifier (1A or 1B) includes a translinear transconductance stage (2B or 2C) receiving an input signal (Vin) of the operational amplifier and operative to produce a first current (ID18) having a square-law relationship to the input signal (Vin) and a folded cascode operational amplifier (3B) including a differential input stage coupled to receive the input signal (Vin), a folded cascode stage coupled to the differential input stage, and a class AB output stage (45) coupled to the folded cascode stage. The differential input stage includes a tail current source (34) coupled to the translinear transconductance stage and operative to produce a square-law tail current (ID34) scaled to the first current (IDI8) to provide a substantially constant input transconductance for a relatively large range of magnitudes of the input signal (Vin).

摘要:
A transmitter includes a combiner for combining plural data signal sets into a single set of data signals. An I/Q modulator modulates the single sets of data signals onto for example an intermediate frequency (IF) carrier signal. A frequency upconverter converts the frequency of the IF signal to a radio frequency signal which, when amplified in a power amplifier, is transmitted via antenna. Using the present invention, plural sets of quadrature modulated signals separated in frequency are transmitted on a single RF carrier rather than on two carriers.

摘要:
An improved vacuum sewerage system for transmitting sewage through an intermittently opened sewage control valve of a transport conduit by means of differential pressure. The vacuum conduit is laid out in a saw-toothed fashion, having a riser, a low point, and a downslope. When no sewage is being transported through the conduit, any residual sewage in the conduit collects in the low point, with minimal intermittent closure of the conduit over time to permit minimal drop in vacuum or subatmospheric pressure throughout the conduit such that there is more than adequate vacuum or subatmospheric pressure available to operate the control valve. When the control valve is opened, the sewage transported through the vacuum conduit forms a generally hollow cylindrical mass, which is propelled toward a vacuum collection tank. The system includes an electric air admission controller ("EAAC"), which automatically opens and closes an air control valve independently of the level of accumulated sewage upstream of the sewage control valve, in order to inject additional air at atmospheric pressure into the vacuum transport lines to apply additional fluid pressure to a mass of sewage therein, and to avoid a waterlogged condition by supplementary transport. A conduit line having more than 13 feet of total lift is thereby possible, provided that the sum of the pressure losses across all the risers equals or exceeds the sum of the minimum subatmospheric pressure condition available at the vacuum collection station minus the pressure head required to operate the control valve.
