Title: Stone tongs for excavators
IPC: E02F3/96
Filed: 1989-02-16
Granted: 1993-08-04
Abstract: These stone tongs for excavators solve an old problem, namely that large stones present in the excavated earth cannot be lifted with an ordinary excavator shovel. This problem is solved by the invention by means of two additional gripper arms or tong elements (1) which can be mounted on an ordinary excavator shovel (2) and hydraulically controlled. Very large excavated stones can thereby be gripped in a tong-like manner and removed.

Abstract: L'invention concerne un moteur à gaine blindé antidéflagrant (1) pour l'entraînement d'une machine en contact avec un liquide, notamment un moteur à gaine d'une pompe centrifuge pour le refoulement de liquides détonants. Puisque le refroidissement direct par un flux dérivé de liquide refoulé parcourant le moteur (1) pose problème, l'invention prévoit un refroidissement indirect avec un échangeur de chaleur (9) disposé dans la région de l'espace rotorique (8) et traversé par un fluide venant de l'extérieur dudit espace (8). Une ouverture (15) ménagée à la sortie de l'espace rotorique (8) permet d'y réduire le dépôt de particules solides et d'empêcher les chutes de pression dangereuses en aval des espaces de coussinet et antidéflagrants. La dimension de cette ouverture (15) est telle que d'une part elle assure la ventilation de l'espace rotorique (8) lors de la mise en marche du moteur à gaine (1), mais que d'autre part elle limite le passage de liquide à un minimum qu'on peut atteindre.

Abstract: The guide catheter system (10) for use in the treatment of coronary artery disease includes a first single-lumen catheter (12) of a relatively large internal diameter to pass a second guide catheter (26) therethrough. The first guide catheter (12) comprises an elongated flexible tube having a stainless steel braid (14) embedded in the wall thereof for imparting desired torqueability characteristics to it. The first guide catheter (12) is intended to be inserted at an appropriate point in the vascular system and then advanced until its distal end reaches the coronary ostium. The second guide catheter (26) is fabricated by extruding a plastic, such as polyurethane thermoplastic resin over a tubular Teflon TM core (28) and because it is to be used within the lumen (24) of the first catheter (12), it need not include a braided structure within its walls to prevent it from kinking. This allows the second catheter (26) to be sufficiently slim to permit it to be advanced into a coronary artery while allowing fluids to be perfused between the outer wall of the second guide (26) and the inner wall of the first guide catheter (12) while still providing a sufficiently large inner lumen to pass a working catheter, e.g., an angioplasty or atherectomy catheter. An atraumatic tip (30) is attached to the distal end of the second guide catheter (26). <IMAGE>

Abstract: Process for the improvement of the sulphur yield of an assembly which produces sulphur from from H2S and which consists of a sulphur plant (1), an oxidation and hydrolysis unit (2) and a purification unit (3). Said sulphur plant (1) in producing sulphur provides a residual gas (17b) which incorporates H2O, COS and/or CS2 and H2S and SO2 in a mol ratio of H2S:SO2  >/=  2:1. Said residual gas passes into the unit (2) on a H2S oxidation and COS and CS2 hydrolysis catalyst which functions between 180  DEG C and 700  DEG C, in the presence of air (47), thus producing a residual gas (38) free of COS and CS2 and incorporating H2S and SO2 in a mol ratio which is kept equal to 2:1 by regulating the air flow (47). The residual gas (38) is introduced into the purification unit (3), in which H2S and SO2 are made to react in order to produce sulphur and to obtain a purified residual gas (45).

Abstract: To aerate liquids or to wash gases, these should be dispersed to a large surface area. For this purpose a for example  cylindrical hollow body (1), having an aeratable hollow space (2) passing axially through its length, is provided internally and externally with a porous jacket (1), filled with a packing (4) and allowed to rotate just under half immersed in the liquid. To prevent for example air being forced to circulate in the hollow body, at least one longitudinal wall (3) is incorporated, which preferably extends from the external jacket to the internal jacket (1). Pressure aeration or deaeration of the hollow body can also be provided. Additional scoop devices (5) around the hollow body can pour liquid over the latter during the rotation. The above considerations also apply to immersed discs, in such a way that between each pair of neighbouring discs (7) a sealing strip (6) and also an axial hollow space (8) are provided, ventilation of said hollow space further improving the general aeration effect. An additional improvement in efficiency is obtained by blowing air between the discs. Instead of air oxygen-enriched air, oxygen or a gas to be washed may be used. <IMAGE>

Abstract: A polyphonic (e.g. stereo) audioconferencing system, in which input left and right channels are time-aligned by variable delay stages (10a, 10b), controlled by a delay calculator (9) (e.g. by deriving the maximum cross-correlation value), and then summed in an adder (2) and subtracted in subtracter (3) to form sum and difference signals. The sum signal is transmitted in relatively high quality; the difference signal is reconstructed at the decoder by prediction from the sum signal using an adaptive filter (5). The decoder adaptive filter (5) is configured either by received filter coefficients or, using backwards adaptation, from a received residual signal produced by a corresponding adaptive filter (4) in the coder, or both. Preferably, the adaptive filter (4) is a lattice filter, employing a gradient algorithm for coefficient update. The complexity of the adaptive filter (4) is reduced by pre-whitening, in the encoder, both the sum and difference signals using corresponding whitening filters (14a, 14b) derived from the sum channel.
