Abstract: According to one aspect of the invention, all of these difficulties are met by using on the helmet an exhaust regulating valve comprising a collapsible and expansible housing including a hinged flap (29) and a peripheral bellows wall (32) on the flap, an orificed seat (33) in the housing covering an outlet opening in the housing, and a flexible membrane (37) adjacent to the seat and connected to the flap (29) so that hingeing movements of the flap (29) in response to pressure variations in the helmet effect progressive laying of the membrane (37) on to and progressive lifting of the membrane (37) from the orificed seat (33). A further safety feature is a shut-off valve (45) whereof the seating is at an inlet opening in the housing and the closure member (47) is on the hinged flap (29). 
     According to another aspect of the invention, lung ventilation is obtained by using demand-type supply and exhaust valves, and spring-loading them both to the open position. It is found that the work of opening one is done by the other and vice versa, rather than by the user of the equipment.

Abstract: Des profils de dents d'engrenage (11, 13) possedent une capacite de couple superieure a celle des engrenages anterieurs a engrenements fins. Pour compenser la faible resistance a la flexion des dents fines (11, 13), la force transmise est divisee par deux a cinq fois le nombre de dents qu'il y a dans un engrenage conventionnel, en utilisant des angles a tres basse pression, et on evite l'interference des dents (11, 13) qui se produirait entre des dents a developpante engrenees (11, 13) a angle de pression egalement petit en utilisant des profils ayant un rayon de courbure relativement plus court. L'elasticite de la dent (11, 13) pour compenser la separation de la dent (11, 13) aux extremites de la ligne d'action et pour assurer une repartition equitable de la charge parmi le nombre maximum de dents (11, 13) est obtenue en approfondissant les creux de l'engrenage au-dessous de la circonference primitive. Il en resulte une dent (11, 13) offrant une plus grande capacite de couple en portant au maximum le rapport de contact transversal et en reduisant au minimum le bruit de fonctionnement par augmentation du rapport de contact axial.

Abstract: Piles for off-shore oil and gas well platforms, are driven into the ground by the extension of a hydraulic jacking cylinder (40). The cylinder, which may be above or below the water surface, is held in position by a working tower or other column (28). The pile, whether one piece or in sections (30) can be contained within the tower or column (28). A plurality of column sections (30) connected end-to-end can serve as the column. Successive pile sections of multi-section pile can be brought into position by securing them to a horizontal loading door (32) of the working tower (28) and then raising the door pivotally. The section is then suspended within the working tower (28) and aligned with the preceding section by an internal alignmenttool (38) prior to welding. Electro-osmosis may be used to reduce soil friction.

Title: Selective-call communications receiver
Inventor: WYCOFF KEITH H
IPC: H03G3/34
Filed: 1980-10-10
Abstract: The signal absence detector controls an operator circuit which periodically provides an operator signal to render the processor circuit (12) in a communication receiver (10) operative. The absence detector responds to a processed signal which is not of a predetermined character to terminate the operator signal. In one form of the invention, the operator circuit is a battery saver (20) which intermittently provides a supply voltage. When the incoming signal is of the predetermined character, the supply voltage continues. The absence detector terminates the supply voltage when it is determined that the incoming signal does not have that character. In another form of the invention, the absence detector is employed in a scanning receiver, in which case the operator circuit steps the receiver between the various channels. The receiver will remain tuned to a channel as long as the incoming signal may be of the predetermined character. As soon as determination is made that the incoming signal does not have such character, the receiver is stepped to the next channel.

Abstract: A process for the hydrolysis of cellulose from vegetable raw materials to glucose, particularly using wood as the raw material, comprises conveying the raw material through a hydrolysis zone in finely comminuted form, the raw material being impregnated with dilute acid and at a sufficiently high hydrolysis temperature. The raw material impregnated with dilute acid is supplied in portions and continuously through the hydrolysis zone where it is heated to a hydrolysis temperature of above 250 DEG  C. by means of high pressure steam. This takes place in an extremely short time accompanied by a sudden pressure rise. Apparatus for performing this process comprises a tubular reactor having at least one straight pipe through which can be conveyed an endless piston chain. The pistons of this chain form a leakage gap opposite the inner wall of the pipe and, in each case, two adjacent pistons define a piston chamber. A high pressure steam line is arranged to issue approximately into the center of the pipe.
