    摘要: A apparatus composed of a flexible bag containing a biological fluid in an enclosure sealed by a cover. The flexible bag is connected to a cavity in the human body through a tube that passes through a cover in the enclosure. In order to supply the biological fluid under an adjustable pressure to the cavity, the enclosure is connected to a source of pressurized air by means of an adjustable valve and a pressure regulator so that the pressure of the liquid in the cavity remains constant.

    摘要: In a knitting machine, a selection latch having two end positions for selecting a knitting-needle is actuated so as to engage a cam which moves the selected latch towards a second end position. The actuation of the selection latch in two stages reduces the displacement brought about by the actuating means and increases the selection frequency. According to the invention the latch is actuated by a thin needle similar to a needle-printer needle, producing an impact on the latch, resulting in transmission of motion with high efficiency and moving the latch into an intermediate position in which the cam brings the latch into its second end position. This substantially eliminates friction between the actuating means and the latch, and enhances the selection frequency.

    摘要: The method involves the use of two nozzles (5 and 6) which alternatively blow air jets against a yarn in the central portion of a channel (1), these nozzles being symmetrically placed in relation to a plane containing the channel axis. The jets blowing frequency is of several hundreds of Hz. A deflector (3) in the bottom of channel (1) can deviate the beating thread sidewise and consequently impart thereto alternate twisting and untwisting motion in order to unravel the thread.
