Title: Charcoal and fuel prodn. by pyrolysis of ligneous materials - using re:vaporised pyrolysis vapour condensate as process fuel
Inventor: GEORGES BRUNO
IPC: C10B53/02
Filed: 1980-08-22
Abstract: Pyrolysis of ligneous materials is effected by drying and carbonising the material and condensing the pyrolysis vapours. The improvement comprises partially revaporising part of the condensate and using the resulting vapour to supply the energy required to allow simultaneous prodn. of charcoal and fuels without an external heat supply. The ligneous material (e.g. wood) is fed into the dryer, where it is dried by contact with hot flue gas produced by combustion of carbonisation off-gas and revaporised pyrolysis condensate. The dried material is fed into the pyrolyser where it is carbonised by contact with hot flue gas produced by carbonisation off-gas.

Title: System for reprocessing used or waste polyethylene film - with removal of soluble contaminants and reconstitution as dry pellets
IPC: B29B17/04
Filed: 1980-09-19
Abstract: Integrated system incorporates a cutter (1) for chopping used or waste film and discharges to a humidifier such as a cyclone (2) with sprays to provide a twin screw mixer (3) with a wet particulate feedstock. Wet mixing followed by draining (5) and rinsing (7) leaches out soluble contaminants after which residual moisture is removed. by use of e.g. separators (9) and drying towers (11-13) utilising hot (80-90 deg.C) air. The dry chopped matl. may be held in silos (14,15) prrior to dry extrusion/granulation of bulk storage (22,23) or pellets ready for re-use. The appts. provides for continuous recycling of waste film starting with wet and/or dry material to produce pelletted matl. from which soluble contaminants have been substantially removed.

Title: Eddy-current detection of flaws in metallic product - operates by moving helically in alternating magnetic field of series windings
Inventor: SAGNIER JEAN ROBERT
IPC: G01N27/90
Filed: 1980-11-12
Abstract: The product (2) which may be a cylindrical rod is moved through the field of two symmetrical windings (6,7) in series on collinear branches of the H-shaped magnetic circuit, whose crossbar carries the inducing winding (5). Eddy currents modify the EMF induced in the nearer winding (6) so that the alternating voltage between the winding terminals can be represented as a rotating vector having a phase shift w.r.t. the inducing voltage. Defects in the product are detected from variations of the phase angle of this vector. Two such probes (1a,1b) are superposed symmetrically about the horizontal plane of motion of the product, whose helical movement produces a slight offset between their responses to flaws.

Title: Sterilising hollow knife for draining blood from cows etc. - involves pre-wash followed by soak in sterilising liq.
IPC: A61L2/18
Filed: 1980-11-28
Abstract: A process and equipment for sterilising a surgical type instrument, partic. a hollow knife for draining blood from an animal, e.g. from the aorta of a cow. The knife is suspended, blade downwards from support brackets at the top of the steriliser. The blade is first washed with a spray of liq. pref. cold water. A tank located below the blade and contg. a sterilising liq. is raised to immerse the blade in the liq. After the blade has been sterilised and the tank lowered clear of the blade, the washing sprays are pref. used to rinse the blade again. Used for washing and sterilising hollow knives for draining blood from animals esp. cows. Congealed blood from one animal is not brought into contact with the next animal. The steriliser provides a suitable, safe storage place for a knife which is not in use. A continuous flow of fresh sterilising liq. can be circulated through the tank.

Patent FR-2507265-A1 (FR)
Inventor: BEDUE ABEL
IPC: F16C32/06
Filed: 1981-06-05
Abstract: The invention relates to a device which is intended to facilitate movement between two elements, in particular a fixed element and a moving element. Examples which may be mentioned are a radial bearing or an axial/thrust bearing. The invention is distinguished by at least one supporting shoe (1, 21, 31, 41, 51), which can be pivoted about a supporting component (3, 23, 33, 43, 53) which, for its part, can move into a cylinder under the action of a first adjustable pressure of a first fluid in order to position the supporting shoe relative to the said moving element. A second fluid is introduced at an adjustable pressure between the supporting shoe and the moving element and forms a layer between the supporting shoe and the moving element so as to give rise to a load-bearing hydrostatic and/or hydrodynamic force of the supporting shoe. Area of application: bearing technology.

Title: Controller for domestic water heater using heat pump - has timer to ensure off-peak operation and has simulator circuit to delay use of auxiliary element until last possible moment
Inventor: ODDOU JACQUES
IPC: F24H4/04
Filed: 1981-12-31
Abstract: The arrangement uses a heat pump as the principal heat source and an electric resistance heater as an auxiliary heat source. A timer relay ensures that the heater is operative only during the times when off-peak electricity tariffs apply. The heat pump is controlled by a conventional thermostatic switch, and the auxiliary element is controlled by a delay circuit which delays the switching on to stagger the onset of the off-peak load on the supply system. The control circuit monitors the water temp. and generates a ramp function, simulating the heating time. This function is used to determine the moment of switch-on so that the water has just reached full temp. when the off-peak period finishes.
