Patent FR-2512808-A1 (FR)
Title: Thermal insulation of homes against heat - by using walls made of foamed poly:aluminosilicate(s), which absorb and desorb water according to ambient temp.
Inventor: DAVIDOVITS JOSEPH
IPC: C04B38/00
Filed: 1981-09-17
Abstract: The homes are provided with walls or partitions made of a geopolymer foam. The thermal insulation capacity of the foam is increased by the cooling produced by the evapn. of zeolitic water contained in the foam. The foam is pref. made on site in shuttering. The foam is pref. based on potassium polyaluminosilicates, and/or sodium-potassium polyalumino-oxysilicates, made by expansion and polycondensn. of a mixt. with molar ratios:- M2O/SiO2=0.2-0.48; SiO2/Al2O3=3.3-4.5; H2O/Al2O3=10 - 25; and M2O/Al2O3=0.8-1.6. The foam may be covered by a non-expanded layer of the same material. The foam has a low density, but also possesses a zeolitic character, i.e. it has the capacity to absorb and desorb water vapour according to the relative humidity of the atmos.
Patent FR-2513227-A1 (FR)
Title: Twin hook attachment for abattoir overhead carcass conveyor - has feet suspension points which can be set at different spacings
IPC: A22B7/00
Filed: 1981-09-21
Abstract: The hook attachment has spaced suspendisuspension points, one for each of the two rear feet of the carcass. The normal spacing of the suspension points pulls the legs apart so that the cleaving operation is facilitated by the half-carcasses falling away from each oter as the cleaving blade progresses downward. Each suspension point is located near the outer end of a cantilever bar which is retractable into a housing centred between opposed cantilever bars. With the bars in their retracted positions, the two suspension points are much closer together than at their normal spacing. Each cantilever bar is pref. locked automatically at either its extended or retracted positonposition. The automatic lock is released by pivoting the bar from its horizontal position to allow it to slide between alternative locked locations. The two cantilever bars pref. slide on parallel paths and overlap each other in their retracted positions. By moving in the cantilever bars after the cleaving operation the widely-spaced, half carcasses are pulled throughtttogether to take up no more room than the original carcass. This previously required transferring from a wide-spaced suspension point hook to a narrow-spaced suspension point hook. This time-consuming and arduous task is now eliminated and only one hook used.
Patent FR-2516003-A1 (FR)
Title: Tool step controller for large scale precision drilling machine - uses slider transmitting motion to tool carriage through double-acting hydraulic cylinder with controlled hydraulic pressure
IPC: B23Q16/04
Filed: 1981-11-12
Abstract: The arrangement is used in conjunction with high precision drilling of large dia. heat exchanger plates for nuclear installations ensures that the positioning of the tool is correct, to an acceptable accuracy, before any machining operation can commence. The tool carriage is displaced by a step numerical controller. A slider mounted freely in translation relative to the base acts on a transmission link formed from a double-acting hydraulic cylinder with a pushrod which moves in the direction of translation when aligned with the slider. A detector of the presence of the slider cooperates with a bracket carried on the slider, sending an electric signal to a solenoid valve which stops the hydraulic supply. The hydraulic cylinder used is a dual piston unit with the hydraulic fluid injected at the centre.
Patent FR-2517041-A1 (FR)
Title: Electric tunnel furnace hottest along centre - where long IR radiation from stainless steel tubes is conc.
IPC: F27D11/02
Filed: 1981-11-20
Abstract: An electric tunnel micro-furnace has an internal wall consisting of lengths of fine stainless steel tubes connected together to form a high resistance electric element. A large current at low voltage is produced a controlled temp. of 250-400 deg.C with radiation predominantly long infra-red and concd. in the centre of the furnace. The furnace may be harnessed to an extruder to vulcanise elastomer or polymerise plastics sections as they are produced.
Patent FR-2517052-A1 (FR)
Title: Three=dimensional object surface reconstruction - determines coordinates from correspondence between sets of images grouped in pairs and uses optical illumination of points
Inventor: BORRELLY JEAN-JACQUES
IPC: G01B11/25
Filed: 1981-11-24
Abstract: The procedure involves successively illuminating zones (Z) to points on the surface to form images at two observation positions (101, 102). Each observation position has an objective lens (11, 112) with optical centre (01, 02) and optical axis (91, 92) and a photosensitive surface (121, 122). The illuminating source (S) lies on the line joining the optical centres (01, 02). The zones (Z) lie on curve at the body surface, each point of the curve belonging to a different plane passing through the optical centres. A correspondence is established between the point images (Y1, Y2) in the zone images (y1, Y2) at each observation position, which verifies the relation existing between the two pairs of coordinates associated with each of the point images corresponding to the same point object. The three-dimensional coordinates of the point objects are determined and thus the form of the surface of the body may be established. The appts. has two cameras at the observation positions, a light source, and a computer for determining the correspondences between images and thus the three-dimensional coordinates.

Title: End cap for bottle - has outlets in base selectively opened to bottle interior when cap is rotated
Inventor: HAKALA TIMO OLAVI
IPC: B65D47/24
Filed: 1982-01-21
Abstract: The end cap for a bottle forms a cup with the base (6) closing the mouth of the bottle (1). The side walls (7) enclose a collar (2) which retains the cap on the bottle. The base has a discharge orifice (11) by which it is connected to an obturator (10) to prevent communication between it and the interior of the bottle. The cap, when in the closed position on the bottle neck, closes the outlet communication. When the cap is moved on the bottle mouth in the direction of the collar plane, it opens communication. The obturator has an annular groove in the base of the cap aligned with the side of the collar.

Patent FR-2502385-A1 (FR)
Inventor: WIESER TIBERIUS
IPC: H01F7/16
Filed: 1982-03-12
Abstract: An electromagnet (1) has a displaceable armature (6), a coil (7) through which current can flow, and a magnetic circuit which is formed by a core, two limbs (3) which are arranged laterally at a distance therefrom, and an upper (4) and lower (5) yoke. The two limbs can also be formed by a closed, for example cylindrical, housing (3). In order to adjust the magnetic force acting on the armature (6), on the basis of the electrical current flowing through the coil (7), an adjustable magnetic reluctance (13) is provided in the magnetic circuit. This magnetic reluctance preferably consists of an adjustable air gap (13). For this purpose, the core (2) is constructed from two parts (2, 12) which can be displaced axially with respect to one another and between which the adjustable air gap (13) is formed. The adjustable air gap can also be formed between the housing (3) and one of the yokes (4, 5), or between two parts of the armature (6) which can be displaced axially with respect to one another. The air gap (13) is mechanically easily adjustable via a screw (10) which is accessible from the outside.

Abstract: The system includes a mother board (101) formed of a printed circuit (133) and heat sink (134) supports two electrical connectors (135,136) between which the substrate (106) is carried. Two circuits (131,141) of chip-carrier type are bonded conventionally to the underside of the substrate (106), and housed in recesses (151,152) in a heat radiator (142). An electrical connection circuit links the electronic components to the end connectors (135,136).
