Title: Apparatus for feeding separator strip, and cutting it to length
IPC: H01M2/14
Filed: 1994-12-14
Granted: 1998-04-27
Abstract: An apparatus for feeding separator strip 14, and cutting it to length in apparatuses for producing pockets for battery plates has a feed device 2 which feeds the separator strip 14 to an apparatus 3 for cutting the separator strip 14 into individual separator strip sections, and has a further feed device 1, which supplies separator strip sections to a device for folding the separator strip sections around battery plates. The feed devices 2 and 1 for the separator strip 14 and the separator strip sections are conveyor belts 10 to which a vacuum pressure is applied, which have a number of rows of holes, and which are passed over chambers 15 to which a vacuum pressure is applied. Those sides of the chambers 15 (to which a vacuum pressure is applied) which face the conveyor belt 10 have slot-like openings, which are aligned with the rows of holes in the conveyor belts 10. The effective length of the slots of the chamber 15, to which a vacuum pressure is applied, of the feed device 1 which is arranged after the device 3 for cutting up separator strips 14 is variable. <IMAGE>

Abstract: A device comprises means for distinguishing a short depression from a long depression depending on the period of actuation of a control button (block 14), means for selecting in the case of a short depression a minutes correction mode in which the display advances by one minute for each pressure (block 18) and, in the case of a long depression, an hours correction mode in which the display advances by complete hours as long as the depression lasts (block 19). It further comprises means for defining two different advance speeds, a slower speed (SLOW+60 m) and a faster speed (FAST+60 mn) in the hours correction mode, and means for passing automatically first to the slow speed to advance a first hour and then to the fast speed for the following hours.

Abstract: The invention relates to a steam pressure cooker, which essentially consists of a lower pot and a cover unit sealing the lower pot. The lower pot has a smooth circular pot rim. The cover unit consists of a lower lid and an upper lid. The latter is designed as a sealing element, which engages the lower part of the pot rim by the flanges. As an improvement of this type of pressure cooker, it is proposed that the upper lid contain two half-lids, and that each half-lid be able to rotate about its own axis of rotation essentially parallel to the central axis of the pot (geometrically vertical) relative to the lower lid and lower pot, and further, that the axes of rotation lie eccentric to the pot's central axis and diametrically opposite each other with respect to this axis swivel mechanism rotatably supported concentrically on the lower lid.
