Title: Procede de traitement d'image par gradation et appareil pour systeme de reproduction d'image radiographique
IPC: G06T1/00
Filed: 1979-12-26
Abstract: Procédé de traitement par gradation d'un radiogramme du thorax dans un système de reproduction d'image radiographique où l'on balaie un radiogramme avec un faisceau de lumière et où l'information du radiogramme du thorax qui y est enregistrée est lue et transformée en un signal électrique et où ensuite une image est enregistrée sur un milieu enregistreur grâce à un signal électrique. Il est caractérisé en ce qu'on abaisse le niveau du signal électrique correspondant à la limite entre les poumons et le coeur de l'image du thorax pour abaisser la densité de l'image à la limite, grâce à quoi le contraste du coeur est abaissé et le contraste des poumons est augmenté dans l'image enregistrée sur le milieu enregistreur. Application : radiogramme du thorax.

Patent FR-2467278-A1 (FR)
Inventor: KRAEMER ERNST
IPC: E05D15/52
Filed: 1980-04-09
Abstract: The deflecting members consist of flexurally elastic material, for example a spring-steel strip. The guide channel consists of a metal profile (1), for example made of brass, in which two edge flanges (6, 7), which are bent in a C-shaped manner and the open sides of which are directed towards one another, laterally adjoin in one piece a plane web part (5). The guide channel forms a right-angled piece consisting of two legs (2, 3) which are connected to one another by means of a curved middle region (4). So that the deflecting members can run with slight lateral play and without the risk of jamming in the metal profile (1) serving as a guide channel, the metal profile (1) is provided, in each of the two transitional regions between the web part (5) and the edge flanges (6, 7), with a bead (8, 9) extending longitudinally and projecting into the clear profile cross-section.

Title: Safety system for hydraulic lifting appts. - uses dual-threshold hydraulic pressure detection systems controlling movements of lifting arms
IPC: B66C23/90
Filed: 1980-06-06
Abstract: The appts. may be used on a vehicle-mounted crane with a base column jointed to two arms with operating rams. When the lower pressure threshold is attained due to increase of the angle between the arms, further movement and extension of the telescopic arm are prevented. When the lower threshold is attained by extension of the telescopic arm without modification of the angle, further extension of the arm and retraction of the ram rods are prevented. When the upper threshold (corresp. to the max. allowable pressure) is attained, telescopic extension remains impossible and extension of the ram rods is inhibited whilst their retraction is permitted. Total safety is ensured by the impossibility of any movement of the hydraulic control, including rotation of the base and movement of the stabilising props. Telescopic extension locking jacks, their supply valves and hydraulic or electrical accessories are eliminated. An electric circuit feeds a solenoid valve and a dual threshold pressure controller.

Title: Chuck with expansible sleeve mounted on nose cone - uses sleeve in segment connected by rubber layers and housing onto upstands on root of nose
Inventor: LANGLET BERNARD
IPC: B23B31/40
Filed: 1980-09-19
Abstract: The machine tool chuck uses an expandable sleeve (2) of segments (21) connected by layers of rubber (3) having a tapered bore. The sleeve is mounted on a tapered nose (15) relative to which it is displaced axially to effect its expansion and the gripping of a workpiece (P) bore. The nose (15) projects axially from a larger cylindrical base (11) which houses into an adaptor plate (10) fixed (11) to the machine, and two radial steps effect the reduction in diameter. Rotary drive is transmitted to the sleeve by segmental base (11 to 13) upstands (14) engaging rebates in sleeve segments (21 to 25). The number of segments (21 to 25) exceeds the number of upstands (14) by one and one segment is not rebated, the assembly taking up axial (j1,j2,j3) and circumferential tolerances (a) to expand.

Title: Movable solar energy collecting panel - comprises fresnel lenses focussing solar radiation on two pipes carrying heat transfer fluid and tracking mechanism rotating system
Inventor: PAYMAL ANDRE
IPC: F24S23/00
Filed: 1980-09-24
Abstract: The appts. includes two Fresnel lenses. These are formed as long rectangles, with their upper surfaces plane, and their lower surfaces having prisms extending along the rectangle. The lenses lie side by side and are sealed together by a joint made of elastomer material. The lenses form the cover of a parallelepiped box supported in a rigid rectangular frame, with a seal around the top edge. Two metal pipes pass through the bottom of the box and carry a heat transfer fluid. Each pipe lies at the bottom of a V-shaped channel formed by two plane mirrors receiving light from the appropriate Fresnel lens. The upper surface between the mirrors is closed by a thin transparent plate, limiting losses by convection, while an insulating material surrounds the two pipes to prevent conduction losses.

Title: Line selector for sampling gas in IC engine - has motor-driven piston in cylinder to select line connecting to gas analyser
Inventor: BEDUE JEAN ROBERT
IPC: G01N1/26
Filed: 1980-10-22
Abstract: Sampling lines from an IC engine enter a cylinder in which a selector piston travels. The piston has an enlarged section with sealing rings at either end, and in which a diametral hole connects with annular slots. This hole connects with a longitudinal hole in the piston which allows the sample gas to pass into a chamber and via a pipe to a gas analyser. The piston assembly is moved by a screw and nut assembly attached to the piston by a radial shaft. The operator applies power to an electric motor to cause it to step to displace the screw and nut. This causes the piston to move to the selected sample line.
