Title: Fresh air snorkel for divers.
Inventor: SVELUND ERNST JOHNNY
IPC: B63C11/20
Filed: 1991-01-04
Abstract: The fresh air snorkel for divers and similar users has the effect with the result that the diver breathes easier due to breathing the air in through one tube and breathing air out through the other tube based on that it is installed one or several one-way-valves (1, 2) in each tube. The fresh air snorkel is equipped with one mouthpiece (3) which can be arranged to a middle piece (7), if necessary, or directly to two separate inlet and outlet tubes (5 and 6). The inlet tube and the oulet tube can be constructed close to each other so that another person can close his mouth over both tubes without knowing which tube is the inlet tube.

Abstract: Un procédé de commande de suivi de contour au moyen duquel on usine une pièce en suivant le contour d'un modèle avec une tête traceuse. Deux axes (X, Y) donnent des instructions par commande numérique pour une trajectoire et une vitesse d'instruction, et trois axes (X, Y, Z) fournissent la commande de suivi de contour. Une vitesse d'instruction à commande numérique est changée par un circuit de dérivation (2b) de sorte que la vitesse d'instruction à commande numérique (F) est conforme à la vitesse combinée fournie aux trois axes par la commande de suivi de contact, alors qu'une vitesse Fd est envoyée à un interpolateur (2a). La trajectoire des deux axes sert de trajectoire d'instruction à commande numérique, la vitesse sert de vitesse de commande de suivi de contour et elle produisent un mouvement équivalent de la trajectoire de commande de suivi de contour suivie par les trois axes.

Abstract: L'ensemble pour la prévention du remplissage excessif d'un réservoir à stockage de liquides comporte une combinaison d'une vanne de purge de gaz (3) et d'une vanne de trop-plein (4). L'ensemble est conçu pour fonctionner à une vitesse de remplissage maximale permise, et la vanne de purge est dimensionnée de sorte qu'à cette vitesse de remplissage, la pression du réservoir ait une valeur équivalente sensiblement inférieure à une valeur limite de sécurité prescrite par les pouvoirs publics. La vanne de trop-plein (4) est une vanne à ouverture rapide, de préférence une vanne magnétique, dont la pression à l'ouverture est sensiblement plus élevée que ladite valeur équivalente de la pression du réservoir, mais inférieure à ladite valeur limite de sécurité. Les chutes de pression provoquées par l'entrée dans le système de vanne de purge d'un écoulement de liquide, et par la sortie de celui-ci de la vanne de trop-plein entièrement ouverte, sont coordonnées de sorte qu'une sortie de gaz à travers ladite vanne de trop-plein, et une sortie de liquide à travers ladite vanne de purge de gaz, soient impossibles en toutes circonstances.

IPC: F16F9/14
Filed: 1992-07-21
Abstract: A rotary shock absorber suitable for use in a suspension system of a vehicle. The shock absorber is provided with a housing and a rotary shaft supported by the housing for relative rotation thereto. A pressure chamber is formed in the housing and a rotor having a pair of blades is received within the pressure chamber. Further, a pair of partition walls are formed within the pressure chamber to define first and second chambers at both sides of each blade, and the first and second chambers are communicated with each other through throttles. When the rotary shaft is rotated, a high viscous fluid filled within the first and second chambers flows therebetween through the throttles. Due to the flow resistances of the throttles, pressures are generated in the first or second chambers. This pressure generation is used to generate a damping force. The shock absorber is further provided with a mechanism which changes the characteristic of damping force generation depending on the rotational direction of the rotary shaft. In some embodiments, the sock absorber has a stopper function which drastically increases the damping force at the stroke ends.

Abstract: The pad printing machine has a pivotable printing device (2) with a pad (1). An inking device (4) has a closed ink container which is arranged in an upright position and into which the printing block can be immersed through an opening in an inclined position for inking. The inked block is lifted into an ink transfer position, during which process it is doctored. In this position, it is presented in an inclined position to the pad (1) which is pivoted back and is lowered onto the block to receive the ink. When it has been pivoted into the vertical position, the pad (1) is lowered onto the workpiece to be printed. This arrangement allows the evaporation of solvents from the ink container to be greatly reduced. <IMAGE>

Abstract: A description is given of a process and of an apparatus for sprinkling agricultural surfaces by means of a nozzle boom 4. The process according to the invention is distinguished in that the nozzle boom 4 carries out, in addition to its horizontal linear movement in the horizontal direction, a swinging movement about an articulation point 3. In contrast to the known processes in which the water was discharged on a comparatively narrow strip, the process according to the invention discharges, for example, the same amount of water on an essentially greater ground surface, as a result of which said amount of water can percolate better in the ground without puddles being formed. <IMAGE>

Abstract: An injection device has a needle (22) which, when the device is operated, is first caused to project, then liquid is forced out through it, and finally the needle is automatically retracted. The needle (22) extends forwardly from a capsule (18) that can slide longitudinally within a barrel-like body (1), a relatively weak spring (19) normally maintaining the capsule and needle retracted. A more powerful spring (14) acts oppositely on a plunger (26) which, when released, shoots the capsule forward by acting on the liquid therein, and then forces the liquid out through the projecting needle (22). At the end of the forward stroke the plunger (26) and capsule (18) are decoupled and the weak spring (14) returns the exhausted capsule and its needle to the retracted position.

Abstract: The invention relates to a locking device for a casing (1) containing pyrotechnic materials. With inflammation means (4) being in position to inflame the pyrotechnic materials (2), this inflammation is caused by the activation of the inflammation means (4). As long as the inflammation means (4) have not been activated, the casing (1) is kept fixed to a closing element (3) solely by first locking means (5, 6), in such a way that, for internal pressures of the casing (1) higher than a given pressure (Po), the casing is detached from the closing element (3). As soon as the inflammation means (4) have been activated, the casing (1) is kept fixed to the closing element (3) by second locking means (7, 8) at internal pressures of the casing (1) higher than the given pressure (Po). The invention is used for reducing the dangerous effects caused by the accidental activation of pyrotechnic materials contained in a confining casing. <IMAGE>

Abstract: An electronic damping system is disclosed which dampens mechanical resonant vibrations of a gantry beam end (16). The system includes a secondary velocity feedback loop in addition to the main servo motor-tach velocity loop. The resonant velocity of the beam (16) is sensed from the movement of the end of the beam (16). The velocity feedback signal (22) is summed (29) as negative feedback with the velocity command signal (30) from the position controller (28). The resultant sum of the signals are combined to form the velocity reference input command signal (32) to a servo power amplifier (34). The servo power amplifier (34) is connected to a main servo motor (42) which controls the movement of the gantry beam (16) in the Y-direction relative to printed circuit board (20).
