Abstract: ABSTRACT          In a method of replacing a section of an old cast iron main with a new main of plastics pipe material, the section to be replaced is isolated from the adjacent live main after a by-pass is fitted between the section and the main.  One end of the pipe is then pushed up the isolated section until a desired length is located within the isolated section and the other end of the pipe is connected to the end of the adjacent main.  This enables the isolated section to be kept alive solely by gas flow through the pipe from the main and the by-pass can therefore be removed.

Abstract: ABSTRACT OF THE DISCLOSURE         A demodulator for demodulating alternating signals modulated by pulse modulation, or by frequency modulation.  The demodulator requires only a single constant current source, a single ramp voltage producing capacitor, and a sample-and-hold function.  The intelligence contained in the modulated carrier is transformed into a first pulse train, and a second pulse train is produced in response to the first pulse train. The first pulse train samples and holds the ramp voltage, and the second pulse train immediately resets the ramp voltage circuit following each sample.  The held voltage is a replica of the modulating signal, produced without the use of filters for removing the carrier.

Abstract: ABSTRACT      Particulate supply material such as a mixture of synthetic rock precursor and radioactive waste is formed in a rotary kiln and poured into a bellows container which, after sealing with a lid, is subjected to cold axial compression by hydraulic rams; the bellows containers in sequence are passed through an upright cylindrical induction preheater and are then advanced in turn across a support table to a hydraulic ram which moves upwardly within an inverted metal cannister having a refractory abutment at its upper end and which is surrounded by an induction heating coil.  Pressure is maintained at a working temperature of about 1200°C to cause axial compression of the bellows container and slight outward radial expansion to jam the bellows container within the outer cannister.  For safety, the induction heating coil is embedded within a refractory block having a slightly tapered bore which at its lower narrowest end is at most a sliding fit over the cannister whereby the cannister is restrained by the refractory block from excessive outward deformation during the hot upward pressing of the bellows container.  A series of bellows containers are compressed in turn within the metal cannister which then can be sealed and removed.
