Abstract: Dispositif d'accouplement fluidique a soupape (41) actionnee par une tige de soupape (39) s'etendant a travers le couvercle (35), la position de la soupape (41) et de la tige de soupape (39) etant commandee par une spirale bimetallique sensible a la temperature (43). La spirale (43) possede une premiere extremite (45) attachee a la tige de soupape (39) et une seconde extremite (47) recue dans un element d'attache (53) pour empecher un mouvement circonferentiel de la seconde extremite (47) de la spirale (43) de se produire. L'element d'attache (53) comprend des ailettes (57) (59) qui sont paralleles a la surface adjacente du couvercle (35). Apres assemblage de l'attache (53) et de la spirale bimetallique (43), la spirale (43) peut prendre sa position neutre dans le sens radial et dans le sens circonferentiel, apres quoi, chacune des ailettes (57) (59) est attachee a la partie adjacente au couvercle (35) sans provoquer un mouvement radial ou circonferentiel sensible de la seconde extremite (47) de la spirale (43). Il en resulte que la spirale (43) peut supporter des conditions de vibrations extremes, mais elle n'est pas soumise aux phenomenes d'hysteresis qui se produisent normalement avec un montage rigide de la spirale (43).

Abstract: Isomerization of xylenes admixed with other alkyl aromatics of at least eight carbon atoms, particularly ethylbenzene, is conducted at essentially atmospheric pressure at 800-1000° F. with a zeolite such as zeolite ZSM-5 the acid activity of which has been reduced. The operating conditions prescribed, in combination with the reduction of activity of the zeolite, permit replacement by a catalyst containing a zeolite such as ZSM-5 of amorphous silica- alumina catalyst widely used in existing isomerization plants, with great increase in the effectiveness of such plants' operation. Substantially the sole by-products resulting from operation in accordance with the invention are benzene and toluene.

Abstract: A process is disclosed for producing vinyl acetate from methanol carbon monoxide and hydrogen which comprises the following five steps:
     (a) methanol is hydrocarbonylated in a hydrocarbonylation zone to produce ethanol, acetaldehyde, methyl acetate and dimethylacetal, and the products are separated in a separation zone;   (b) methyl acetate is carbonviated in a carbonylation zone to produce acetic anhydride;   (c) the acetaldehyde and dimethylacetal produced in the step (a) and the acetic anhydride produced in the step (b) are converted to ethylidene diacetate and methyl acetate;   (d) the ethylidene diacetate produced in the step (c) is thermally decomposed to vinyl acetate and acetic acid, and the products are separated in a separation zone; and   (e) the methyl acetate produced and separated in the step (a), (c) or (d) is supplied to the carbonylation step (b).   
     The process has advantages over the existing process for producing vinyl acetatefrom ethylene.

IPC: F16D65/46

Abstract: in a disc brake the application of the brake is initiated by angular movement of pressure plates in opposite directions, the pressure plates then moving apart into engagement with friction discs which are urged into engagement with opposed radial surfaces in a stationary housing. The angular movement is effected hydraulically by an actuator comprising a piston (8) working in a bore (7) of a cylinder (5), the axis of which is substantially at right angles to that of the brake. The piston (8) acts through a part-spherical rocking thrust coupling associated with a pull-rod (24) passing through the actuator with a substantial clearance, the inner end of the pull-rod (24) being pivotally coupled to the junction (15) of a pair of toggle links (16, 17) connected between lugs on the pressure plates. The outer end of the pull-rod (24) is extended for connection through a transmission member (31a) to means for applying the brake mechanically. A thrust member (12) is disposed between the piston (8) and the spherical rocking coupling and is engagable with a thrust transmitting force on the piston (8) for sliding movement in a transverse direction with respect to the axis of the cylinder (5) to accommodate angular movement of the pull-rod (24) when the brake is applied.
