Abstract: The invention concerns a method of detecting and removing bulges in continuous strips of material before they enter higher-pressure zones in a dewatering filter press. The method is characterized in that, when a bulge occurs, a sensor is deflected and a control signal generated. The invention also concerns a device for carrying out the method, the device being characterized in that it is fitted with a preferably pressure-tight sensor which is deflected when a bulge occurs in the strip of material being filtered and can be reset when the bulge disappears.

Abstract: A telescoping shipping container for fragile articles and formed of corrugated sheet material includes an upper portion and a lower portion, each respectively having an upper end and a lower end with standard flap closure. The upper portion telescopes completely over the lower portion, to effectively double the thickness of the side walls of the package. The inner/lower portion includes a complete lining of resilient foam padding for further protection of articles contained therein; the inside of the upper lid is also similarly lined. By forming each portion of double plies or laminates of corrugated material, the sides of the closed package or container effectively include four corrugated layers, which along with the resilient foam lining, provides superior protection against penetration and damage to the package. The corrugated material may be cardboard, plastic, or other suitable sheet material capable of being similarly formed.

Abstract: A doctor blade holding apparatus, preferably for coating devices, includes a clamping mechanism which holds, via a mounting plate, a doctor blade support which carries a doctor rod.

A holding strip provided at a back side of the doctor blade support clamps the mounting plate to the doctor blade support. The holding strip is disposed laterally with respect to a mid-plane of the doctor blade support to provide a contact region between a back side of the doctor blade support and the pressing tube which is in substantially the same plane as the mounting plate.

Abstract: The bases and caps are aligned in two stages, with displacement by first pointed pushers (13-31) into corresponding calibrated horizontal channels (12-29) followed by displacement by second pushers (21-44) into corresponding calibrated vertical and descending channels (312-329). The second pusher (21) pushes the bases horizontally into the wider terminal part (20) of the descending channel, where the base is sucked by its sealed end and inserted into the corresponding supporting socket (1), with a vertical disposition and with the opening upwards. The second pusher (44), operating with the caps, acts on the intermediate parts of these with a point (144) which causes the caps to rotate with the opening downwards and transfers them with a vertical disposition into the wider terminal part (42) of the descending channel where the cap is held by a suction tube (46) which inserts it into the corresponding supporting socket (2).

Abstract: A downhole submersible fluid pump having a progressive cavity motor section and a progressive cavity pump section.
