Abstract: An aeration process consists in introducing liquid under pressure into a rotatable hollow body provided with discharge openings and which is rotating in a space containing gas, jets of liquid discharging through the openings impinging on the wall of a container in which the hollow body is located, the liquid being reduced to drops in the space containing gas. The apparatus is characterized in that it has a rotatable hollow body 8 provided with rows of openings 17 from which extend atomizing nozzles 9. Liquid supplied via pipe 10 to the body 8 is subsequently discharged from the nozzles radially outward to the container wall 3. The resulting aerated mixture is discharged via pipe 6 from the bottom of the container. <IMAGE>

Abstract: A device for stopping the machine drive of a needle movable in cooperation with a rotary hook of a sewing, embroidering or tufting machine upon a thread breakage comprises a thread cutting mechanism which includes a thread catcher movable through the needle path and a switching mechanism which is connected to the drive for disconnecting it and which becomes effective upon a thread breakage. The device includes a movably mounted thread feeler carrier having a thread feeler which is adapted to be located between the needle and the rotary hook. The drive mechanism for actuating the thread catcher includes control cams which are engageable with lifting cams so as to project the feeler out of the path of motion of the thread between the needle and the rotary hook. The thread feeler is associated with a piezoelectric element and the deflection of the feeler by the thread produces a pulse which regulates the drive mechanism for the sewing machine and effects the stopping thereof when the threads are cut.

Abstract: The invention concerns a causticizing procedure by which from soda liquor derived from a sulphate cellulose digesting process and from unslaked lime is produced white liquor for reuse in the digesting process, over lime slaking and a subsequent causticizing reaction proper. It is essential in the invention that the lime slaking is carried out using white liquor, whereafter the causticizing reaction proper is allowed to take place between the slaked lime and soda liquor combined therewith. The requisite white liquor is obtained by recirculating part of the white liquor produced by the causticizing process, to the slaking step, where it either completely or partially replaces the soda liquor employed in prior art. By using white liquor, one avoids the foaming, interfering with the process, which is encountered in the slaking step.

The lateral edge zones of the press jacket are both deformed radially inwardly around the outside of the respective supporting disks and each edge zone is clamped there by a annular clamping flange. To facilitate deformation of the edge zones, at least one of the edge zones terminates in a series of tongues separated by cutouts arrayed around the roll. Coiled tension springs engage the edge zone and/or the tongues to pull them in the direction toward the axis of the roll.

Abstract: The foot bearing the seat surface of a seat is divided at a distance of 20-30 cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a, 5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1-T3), the mutual rotation between the two foot parts is ensured. - Due to this construction, the seat surface can be sweveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and owing to the mentioned elastic restoring force, the seat part always retuns automatically to its initial position. When the seat is inclined, the then undesired rotation of the upper seat part 5a is prohibited by the friction between its edge area and the compressed brake ring. - (Dwg.3/7)
