Patent FR-2336621-A1 (FR)
Title: Tube support for heat exchanger bundle - comprises transversal cross-ties with notches top and bottom for holding tubes
Inventor: TRAITEUR RENE
IPC: F16L3/223
Filed: 1975-12-22
Abstract: Each tube row in a heat exchanger bundle is assembled between 2 transversal cross-ties that have notches. The notches of 2 adjacent cross-ties form openings that the tubes pass through and are held by the opening. Each cross-tie sepg. 2 tube rows is made up of independent elements placed one after the other. The ends of each element have shrouded mating surfaces that co-operate with the complementary ends of the preceding and following elements. The joints where the elements of a cross-tie meet are offset to the joints of the elements of the 2 adjacent cross-ties. This joint can coincide with the notch points of the cross-tie. The cross-ties are held by a series of rods that pass through each cross-tie. Each element making up a cross-tie is passed through by >=1 assembly rod. Every rod has at one or both ends an elastic clamping component for adjusting the tightness with which the cross-ties are drawn together. This component comprises at the threaded end of the assembly rod a nut over a compressible washer. Used for suporting elements positioned in rows esp. for supporting tubes in heat exchanger tube bundles. Tubes can be clamped individually and vibration is reduced.

Title: Improved horizon sensor for artificial satellites - uses thermosensitive elements and subtractive compensation elements relative to thermal image of earth
Inventor: DESVIGNES FRANCOIS
IPC: G01S3/786
Filed: 1976-05-24
Abstract: The horizon sensor is for artificial satellites. It uses thermosensitive elements (m1, m2) of equal area (Am) to evaluate the angle of the axis w.r.t. the centre of the earth, whose thermal image is formed on the elements concerned. These elements are aligned and positioned symmetrically relative to the origin of the x,y,z system of axes so that the parts of their sensitive surfaces irradiated at zero pointing error have equal areas. A "subtractive" compensative element (c1, c2) is associated with each main sensor (m1, m2). These compensative elements have areas Ac and are totally covered by the image of the earth.

Title: Fire-resistant polyamides contg. phosphorus - prepd. from diamines and phosphorus contg. dicarboxylic acids (BE210377)
IPC: C08G69/00
Filed: 1976-09-20
Abstract: Prepn. of the polyamides comprises polycondensation of diamines with P-contg. dicarboxylic acids, P-free dicarboxylic and/or amino carboxylic acids in a known manner and under normal conditions. P-contg. dicarboxylic acids of formula (I) HOOC-(CH2)2-P-(CH2)2-COOH are used, (where R is as 1-8C pref. 1-4C unsubstd. alkyl radical, esp. Me).

They are suitable for the prepn. of fibres and filaments and esp. for the prepn. of constructional parts of electrical appatatus and constructional units in large calculating machines. In an example, 19.9 g. terephthalic acid, 16.9 g. bis-(beta-carboxyethyl)-Me-phosphone oxide and 31.4 g bis-aminoethyl norbornane are condensed at 275 degrees C to give, after processing, 58 g. P contg. polyamide.
Patent FR-2372750-A1 (FR)
Title: Storage support for fuel element of nuclear reactor - in which wt. of element is taken in tension to reduce risk of buckling
IPC: G21C19/40
Filed: 1976-11-10
Abstract: The height of a fuel element of a nuclear reactor is larger compared to the diameter, usually 10 to 1. Due to the weight of the fuel and the lightness of the structure there is a high risk of the assembly buckling under its own weight when held in the vertical position. This is overcome by supporting the fuel elements during storage by a parallel column which supports the upper end of the element. The column has a screwed collar at its mid point which compresses a spring fitting around the lower part of the column. The lower end of the spring is supported by the forked end of a horizontal beam.

Title: Applying an aq. surfactant soln. to oil slicks - using the passage of water through a venturi jet to draw up the surfactant into the stream
IPC: E02B15/10
Filed: 1976-12-21
Abstract: Process for applying a surface active agent (I) (e.g. ethoxyiates of alkyl phenois) to an oil slick on water or other oil-contaminated surface comprises passing water through a venturie chamber to draw the (I) into the water jet, and then applying the water (I) mixt. to the oil. Pref. the rate of flow of the water is 22.5-255 1/min and the mixing ratio water/(I) in the mixt. is 1:1 to 100:1, esp. 5:1 to 30:1. Process is esp. useful for use at sea, when a stream of sea water (e.g. from the ships' hydrant) is mixed with the (I) in the ventri and the mixt. is applied to a floating oil slick, e.g. using a boom.
Patent FR-2373734-A1 (FR)
IPC: F16K7/12
Filed: 1977-01-21
Abstract: The diaphragm (4) has a fixing bead (3) which is arranged at the rim and is clamped in a chamber formed between the valve housing (1) and the valve cover (2). With the stop faces of the valve housing and the valve cover resting fixedly on one another, the height of the chamber is designed to be just sufficient to allow the fixing bead a permanently maintained spring-back capacity. This prevents both uncontrolled tightening of the screw fastening between the valve housing and the valve cover and puncturing of the diaphragm by an actuating drive controlled as a function of displacement and by reason of the skew positioning of the drive.
Patent FR-2384228-A1 (FR)
Title: Conicity angle measurement for lateral faces of piston - involves plate giving horizontal surface and reference plane
IPC: G01B5/24
Filed: 1977-03-15
Abstract: The instrument measures the angle of conicity for high performance pistons. By making radial cuts in the piston, the lateral faces converge toward one another and to the axis of the conical segment. The instrument consists of a plate (12) giving a horizontal surface and reference plane (14). A support (20) mounted on the plate carries a measuring wedge (22) pivoting on an axis (24). The lower edge of the wedge is at a predetermined angle. A dial (30) is mounted on the support, and is connected to a vertical needle (32) which is in contact with the upper surface of the wedge. A conical segment of piston (36) with truncated lateral faces (38, 40) is slid along the reference plane until the face (38) is in contact with the lower surface of the wedge, giving a reading on the dial. The angle formed between the face (40) and the reference plane is similarly measured, and hence the angle of conicity is determined.

Patent FR-2375748-A1 (FR)
Title: Permanent magnet variable speed motor - has core and winding installed between field concentrating poles
IPC: H02K23/46
Filed: 1977-12-22
Abstract: The variable speed permanent magnet motor has plate type permanent magnets (4) arranged between field concentrators (2) forming the poles and the motor frame (3). In between pairs of field concentrators (2) is a magnetic material core (5) around which is wound on winding (6). One end of the core (5) is in contact with a field concentrator (2) there being an airgap (9) between the other end of the core (5) and the other concentrator (2). The winding (6) are excited so as to produce in the cores (5) a flux which is in the opposite sense to the flux from the permanent magnets (4). The permanent magnet flux passing through the cores (5) is thus reduced when the windings (6) are excited. Consequently the flux passing through the air gap is reduced and the motor speed is lowered.
