Abstract: Elastomère de polyuréthane et/ou de polyurée préparé dans la réaction entre a) un polyisocyanate organique; b) un prolongateur de chaîne, et c) un polyéther possédant un poids moléculaire compris entre 500 et 10000, ce polyéther étant constitué d'un copolymère bloc d'oxyde d'éthylène et d'oxyde de butylène comprenant un bloc poly(EO) interne lié de chaque côté sur un bloc poly(BO), dans lequel des moitiés d'oxybutylène comprennent de 10 à 90 % du poids total du polyéther. On prépare généralement les polyuréthanes et/ou les polymères par la réaction d'un polyisocyanate avec un polyol et un prolongateur de chaîne. Les polyols d'oxyde de polyéthylène présentent plusieurs défauts très importants qui les rendent inappropriés à la préparation d'élastomères. Le défaut le plus important est que les polymères d'oxyde d'éthylène sont très hygroscopiques, ce qui rend très sensibles à l'eau les élastomères préparés à partir de ces polyols. Les élastomères préparés à partir des polyols d'oxyde de polyéthylène ci-décrits sont moins sensibles à l'eau que ceux préparés à partir de polyols traditionnels contenant de l'oxyde de polyéthylène.

Abstract: The elevated, open-topped housing of a solid fuel-­burning barbecue grille is provided with a hinged top lid (30) and upper and lower swing-out doors (66,68) which respectively carry horizontally disposed food and solid fuel-supporting grate structures (78,80) that are moved out of and into the housing interior, through framed housing side wall openings (60,62), as the doors are opened and closed, thereby permitting food items to be placed on the upper grate, and charcoal to be placed on the lower grate, externally of the housing and without lifting the housing lid. To prevent cooking heat escape from the housing interior when the upper door is opened, a hinged flap (82) automatically pivots downwardly to cover the upper door opening when the upper door is opened. When the upper door is closed, an interior tab (86) member upwardly pivots the flap and holds it in the upwardly pivoted position. Flue means (92) for combustion gas are carried by the housing lid and include a vent pipe (100). Support means releasably support the vent pipe in a selected one of open and closed positions thereof.

Abstract: A guidewire assembly particularly suitable for valvuloplasty procedures have an outer tubular member (30) a first shapable core member (33) fixed within the outer member and a second stiffer core member (31) which is axially movable within the outer tubular member. The first core member preferably has a double curvature shape with the most distal curvature having a much smaller radius or curvature than the second curvature. When the movable core member is moved proximally, the fixed core member assumes its shaped form and thereby changes the shape of the guidewire. The double curvature shape prevents the traumatic engagement of the distal tip of the guidewire with the lining in the heart chamber and also provides supports to the guidewire when disposed through the heart valve.

Abstract: The fabric rolling unit comprises a pair of tangential fabric-rolling rollers (10, 11), one of which is a driving roller (10) and the other one is a driven roller (11), with the axes of said rollers (10, 11) being parallel to each other and horizontal, on which rollers either the beam (18) tangentially rests, on which the fabric roll (R) is wound, or the same fabric roll (R) respectively rests. In order to make it possible large-diameter fabric rolls (R) to be obtained, the beam (18) is supported in a freely revolutionary way at the upper ends of the stems (26, 27) of two vertical hydraulic cylinders (28, 29). Inside the upper chamber (32, 33) of these cylinders (28, 29) a constant pressure is preset, whilst inside the lower chamber (34, 35) of said cylinders (28, 29) the pressure is controlled and varied by means of a proportional valve (47) controlled, in its turn, through an electronic circuit, by a load cell (41) which constantly monitors the variable load (C y ) applied by the beam (18) and by the fabric roll (R) during the rolling process, so as to keep constant the load (C k ) applied to the cell (41).

Patent EP-0417367-A1 (EP)
Inventor: SCHULZ CHRISTOPHER R
IPC: B01D21/00
Filed: 1989-09-11
Abstract: A coarse media flocculator utilizes buoyant media restrained against upward movement in a vertical chamber whose cross-­sectional area increases uniformly in the direction of flow, thereby providing a uniformly tapering velocity gradient. The height of the media restrainer within the chamber can be adjusted, thereby changing the depth and cross-sectional characteristics of the media bed within the tapered chamber. The velocity gradients of the flocculator can thus be changed independent of flow. A washwater piping grid with downwardly pointed jet spray nozzles is positioned within the media bed for cleaning. The height of the media bed can be adjusted by changing the position of the media restrainer or by changing the liquid level within the chamber, thus changing that part of the media bed wherein the jet spray is concentrated. In one embodi­ment, the restrainer is disposed within an area of the chamber above the tapered portion having a uniform cross section. This arrangement facilitates adjustment of the position of the re­strainer and also facilitates cleaning by allowing the restrainer to be repeatedly pushed downwardly, thereby pulsating the media bed. In a second embodiment, a two-piece restrainer is disposed with the tapered portion of the chamber and is adjustable in one dimension. This arrangement allows the cross-sectional and consequent flocculation parameters to be adjusted in both upper and lower portions of the media bed.

Abstract: A method of controlling wire tension of a wire-cut discharge machining apparatus avoids break in the wire by preventing the wire tension from changing excessively because of abnormal operation of an electromagnetic powder brake when the tension to the wire is applied, removed or is changed. When it is judged that he practical wire tension may change excessively based on the of the presently instructed wire tension and a newly instructed wire tension, the processing is repeated to add or subtract the upper-limit change quantity which has been set in advance to a value that will not excessively change the wire tension, to or from a present desired wire tension (tO) at a predetermined period (U) until the desired wire tension reaches the instructed wire tension (tn). The electromagnetic powder brake undergoes the braking operation with an operation voltage corresponding to a desired wire tension that gradually changes, and the practical wire tension gradually changes until the instructed wire tension is reached.
