Title: Mandrel assembly for pressure testing of pipe - uses two sleeves to seal pipe for pressurisation and has diametrical spacing for combined ovalisation loading
Inventor: LESSIRARD LOUIS JOSEPH LUCIEN
IPC: G01N3/12
Filed: 1981-05-05
Abstract: A concrete pipe under test has male and female ends and has a mandrel inserted into it which comprises a sheet steel tube coated inside with concrete. The mandrel has a slightly smaller dia. than the pipe to allow the pipe to be deformed by an external pressure. One end (2a) of the mandrel is welded to a cylindrical sleeve with an annular disc. This disc has a pipe permitting the introduction of fluid to pressurise the pipe while an external force is applied to the pipe to deform it. A second sleeve is attached such that it can be removed to the other end of the mandrel. Flexible rings at each end of the pipe ensure sealing between the sleeves and the pipe.

Title: Polycrystalline silicon solar cells prodn. - by exposing to unipolar microwaves to diffuse dopant
Inventor: CHITRE SANJIV
IPC: H01L21/225
Filed: 1981-06-15
Abstract: Process comprises (a) providing dopant adjacent a polySi substrate surface, pref. by spraying and (b) exposing to a unipolar microwave field to drive dopant ats. to a selected depth, while controlling field frequency, power, duty cycle and/or on-off time to control depth. The devices are also claimed. Field parameters are selected so dopant is driven into Si grains to form shallow junctions, with dopant level at grain boundaries less than in grains and drive-in to grain boundaries insufficient to convert boundaries into conductive short circuits for the junction. Pref. a metal conductor(s) is disposed on the dopant and exposed to a unipolar microwave field simultaneously or subsequently, to sinter the metal to the substrate and form an electrical contact to the doped region. Cell cost is low and energy payback time quite short as dopant is diffused with low energy consumption. It is possible to reduce equipment requirements. Exposure to a unipolar microwave field is useful for diffusion/annealing after ion implantation.

Title: Waveguide corner piece mfg. process - involves cutting wedge shaped slots in waveguide and bending it through required angle
IPC: H01P1/02
Filed: 1981-08-28
Abstract: The rectangular waveguide section in which a change of direction of the waveguide axis occurs is fabricated by cutting out a number of wedge-shaped slots (5) extending from the waveguide wall forming the inner wall of the corner piece waveguide to the outer wall. The section is then bent to close the slots and the mating wall edges secured by brazing or use of an electrically conductive adhesive or similar. For a 45 degrees corner at least two slots are cut out while at least four would be used in a right angle. The distance between slots is chosen such that after bending adjacent slot lines are separated by a quarter wavelength or slightly greater. This avoids unnecessary reflection.

Title: Real-time ultrasonic echo-graph for medical examination - applies quadrature heterodyning process and filtering of analogue input signal prior to spectral processing
Inventor: HON LUCIEN PRUD
IPC: H04L25/30
Filed: 1981-09-24
Abstract: A probe assembly is formed of a number of transducers and a transmission multiplexer and enables only a number of signals to control the probe. The multiplexer is stepped by a sequencer driven from a clock controlled by a central unit. The received echo signals are selected by the sequencer operating a multiplexer to route the signals to a receiver circuit where signal levels are processed as a function of depth. The receiver output is applied to data receiving channels each comprising two channels in quadrature. These are controlled through transmission, reception and processing circuits each controlled from the central control unit. The data outputs are passed to an adder circuit containing a bandpass filter. The adder output is passed to data processing circuits for image reconstruction and its display on a screen.
Patent FR-2494822-A1 (FR)
Inventor: MENTULA JUHA
IPC: F25B47/02
Filed: 1981-11-26
Abstract: A method and an equipment is used for defrosting the vaporiser of compressor refrigerating machinery The invention is intended for use in connection with so-called hot gas defrosting, in which frost and ice accumulated in the vaporiser (4) of the freezing machinery are periodically melted. In the first phase of the method a highly superheated refrigerant is led direct from the compressor (1) to the vaporiser (4). In the second phase the refrigerant which has given up its heat of superheat to the vaporiser (4) is removed from the vaporiser (4) in a superheated state close to the vapour saturation boundary curve so that the refrigerant does not condense in the vaporiser (4). In the next phase the refrigerant vapour pressure in the superheated area is reduced suitably at the compressor (1). Then the possible liquefied drops of refrigerant in the hot gas are vaporised and thus the passage of cold liquid material to the compressor (1) suction valve is eliminated. Defrosting is terminated, when ice formed on the surface of the vaporiser (4) has melted. Equipment comprises a by-pass pipe (8), through which the superheated refrigerant is led past the condenser (2) and pressure reducing means (3) direct to the vaporiser (4), and by a by-pass line (5) through which the refrigerant vapour is led from the vaporiser (4) to the compressor (1), in which the main suction line is closed. In addition the equipment comprises a possible control equipment (16) which terminates the defrosting period directly after the ice formed on the surface of the vaporiser (4) has melted. A pressure reducing device has been arranged to the by-pass line (5) the said device being preferably a fusion capillary (7) or the like.

Abstract: The total sludge is transported upwards with simultaneous drying through the turbulent dispersion/heat transfer medium packed bed, conducted away together with the fluidising gas from above the fluidised bed, and separated from the fluidising gas in a downstream solid separator. The sludge is subsequently burnt in the solids burner. The hot combustion gases, after substantial separation off of the combustion residues has been carried out, are fed to the fluidised bed as the heat-supplying fluidising gas for the sludge drying. An apparatus for carrying out this process has an oblong fluidised bed furnace (1), with intake flow from the bottom, having a plurality of sludge feed positions (4) distributed on its longitudinal extension, a solids separator (6) downstream of its gas space for separating the total dried sludge from the fluidising gas and an intake base of the fluidised bed furnace (1) impinged by the exhaust gases of the solids burner.
