Abstract: L'invention concerne un dispositif de restitution de teintes pour les systèmes utilisant une tête d'impression thermique. Une tête de lecture (2) analyse ligne par ligne un document à reproduire, et délivre un signal analogique dont les variations d'amplitude traduisent les variations de teinte du document. Un convertisseur analogique numérique (4) précédé d'un échantillonneur (3) du signal analogique délivre, pour chaque ligne analysée, n échantillons numériques (n entier positif) correspondant aux teintes à reproduire sur une ligne d'une feuille de papier thermosensible. Pour chaque ligne à reproduire, un ensemble de registres mémoire à décalage (6) génère n signaux de commande qui sont fonction des valeurs numériques des échantillons associès aux teintes à reproduire. Ces signaux commandent un dispositif d'alimentation (7) des n résistances Ri (i variant de 1 à n) d'une tête d'impression thermique. Application aux systèmes d'impression thermique.

Abstract: The arrangement for connecting the probe electrode (5) to the output terminal (1) of the cardiac pacemaker (2) ensures the insulation of the terminal (1) and of the locking screw (9) of the electrode (5) with the aid of a hood (13) screwed onto the terminal (1) in the factory, and which takes the place of a counternut for the screw (9), until the pacemaker is implanted, in order to prevent the screw from leaving the tapping (11) or from obstructing the drill hole (4) as a result of the impacts occurring during transportation and movement from the factory to the operating theatre. Upon implanting the pacemaker, the screw (9) is tightened on the electrode (5) with the aid of the screwdriver (16) which is guided via the opening (15) in the hood (13), which opening is protected by a pad of viscous silicone (17) arranged between two flexible membranes (18,19) which are incised diametrically (at 20), the incision lips (20) returning to their original positions after withdrawal of the screwdriver (16).   <IMAGE>

Abstract: The invention relates to a liquid separating and evacuating device for fluid suction equipment and, in particular, for dental surgery equipment, with which it is possible to separate the air from the liquids and to continuously drain the latter without interrupting the suction. 
     The said device consists essentially of a cylindrical container (2), placed on a vertical axis, that is provided on the bottom part thereof with a draining valve (18). Placed inside the said container there is a horizontal partition (4) that is divided into two superposed chambers. This partition has a valve (16) which either allows or prevents the liquid to pass from the first chamber (5) to the second chamber (6). 
     A float (23) contained in the first chamber (5) controls, by actuating a pneumatic distributor (20), the opening and the dosing of the valves (16) and (18) which successively allow the liquid to pass from the first chamber to the second chamber and from the latter to the outside.

Abstract: A single laser beam emitted from a laser generator (12) driven by a laser driver (14) in a record mode is alternately switched between a recording beam with large power and a tracking beam with small power. The beam switched is focused onto an optical disc (42) through a laser beam transmitting section (30) and then is reflected from the optical disc (42). The reflected laser beam from the optical disc is received by a pair of photo detecting elements (72, 74) in a two-divided way. Pulsate signal components with peaks corresponding to the recording beam contained in the output signals produced from the photo detecting elements (72, 74) are removed by sample-hold circuits (88, 90) in a wave-shaping section (80). A level difference between the output signals from the wave-shaping section (80) is detected by a differential amplifier (130). The output signal (TC) from the differential amplifier (130), that is, a tracking control signal, drives a drive section (132) to move an optical head (82).

Abstract: A belt clamp in a vehicle seat belt system having an emergency locking retractor (40) comprises a U-shaped frame (42), a belt turning roll (60) around which the belt (B) is looped and which is carried by a pair of spaced-apart levers (66), one at each side of the frame, which are rigidly joined together and are mounted on the frame for rotation about an axis (70) transverse to the sides of the frame. Springs (72) normally hold the turning roll (60) and levers (66) away from a movable clamping jaw (56) which is supported by the frame for movement towards and away from a matching fixed clamping jaw (54) and which is biassed by springs (59) away from the fixed jaw to allow the belt (B) to move freely between them (Figure 2). If the retractor (40) locks and there is a substantial pull-out force exerted on the belt, the springs (72) yield to permit levers (66) and the turning roll (60) to pivot towards and into engagement with the movable clamping jaw (56) so that the jaw (56) is pushed towards the fixed clamping jaw (54), whereupon the belt (B) is gripped between gripping surfaces of the jaws and is prevented from being pulled out from the emergency locking retractor (Figure 3).

Abstract: An ink jet printer includes an ink supply system for supplying ink through the print head (10) of the printer. The fluid supply system includes a pump arrangement (22) supplying ink to the print head (10) from a supply tank (16) via a fluid supply line (56). A plurality of ink return lines (40, 42, 44) are connected between the pump outlet (26) and the pump inlet (24). Each of the ink return lines includes a flow restriction (46, 48, 50), with the flow restriction in each line providing a fluid flow impedance which differs from the impedances provided by the other flow restrictions. A valve arrangement (52, 54) connects the pump outlet (26) to selected ones of the ink return lines, to provide means for controlling the flow rate of ink supplied through the ink supply line (56) to the print head (10). During periods in which the printer is shut down, a substantially reduced ink flow through the print head is continuously maintained at a reduced fluid flow rate and at a reduced fluid pressure.

Abstract: The depth control system is for a disk tiller or similar ground-working implement having a gang of tillage tools (18) on a sub-frame (20) adjustably supported from a main frame (12). A trailing support arm (40) is rigidly connected to the sub-frame (20) and carries a gauge wheel (58) on an arm (50) pivotally mounted at (64), the wheel being spring-biased into engagement with the tilled soil. As the depth of the tools (18) varies with changing conditions, the support arm (40) moves and the gauge wheel arm (50) pivots with respect to the support arm to rotate a first lever (66). The first lever is connected to a second lever (68) by a pair of pretensioned springs (76,78). Movement of the second lever moves a switch actuating arm (80) which actuates one of a pair of microswitches (82, 84). The microswitches control a solenoid valve (100) to operate a depth control cylinder (36) for the sub-frame (20) so as to maintain the desired depth of cut. The switch actuating arm (80) is damped by a dashpot (90) which, together with the springs (76, 78), prevents switch actuation during short periods of oscillation.

Abstract: A sealable pressure vessel (5) has a closure member (8) held on by means of a bayonet fixing member which is movable between two positions while retaining the mechanical linkage between the vessel (5) and the closure member (8) forming a container (1). The bayonet fixing comprises a vessel lug (18) which co-operates with a stepped slot (17) in a locking ring (9) secured to the closure member (8). In one position of the lug (18) in the slot (17) the closure member (8) is sealed on the vessel (5) and the container is closed to atmosphere while in another position the seal is broken and the container is open to atmosphere. The closure member (8) incorporates a sliding valve (29) which has a spring urged piston (31) carrying a locking pin (32) to lock the lug (18) within the slot (17) when the container is closed to atmosphere. The piston (31) can vent the container to atmosphere when the closure member (8) is sealed to the vessel (5) if the piston (31) is raised since it then connects the interior of the container to atmosphere via a chamber (47) and two ports (48) and (52). Raising the piston (31) disengages the locking pin (32) from the lug (18) so that the closure member (8) can be removed from the vessel (5).
