  • Publication number: 20240075403
    Abstract: The invention relates to a thin film evaporator (D) for producing a transfer mixture according to the direct dissolution method, having a feed (1), a housing (4) and an outlet (2), wherein the feed (1) introduces a starting material, made of cellulose, water and a functional fluid, into the housing (4), wherein an evaporator shaft (5) situated in the housing (4) rotatingly sweeps the starting material over the heated interior of the housing (4), wherein the product is heated and some of the water evaporates so as to result in the transfer mixture, which flows to the outlet (2) together with a supply stream, wherein the through-flow capacity of the outlet (2) is greater than the supply stream.

  • Patent number: 8052259
    Abstract: Ink cartridge (10) which is insertable (insertion direction 11) into an inkjet printer, or cartridge receptacle associated therewith, and which has a housing (13) on at least one wall (12) of which there is arranged a plate (21) comprising electrical contacts (20) and an element for storage of cartridge-specific and/or printer-specific data. The housing (13) is delimited by two side walls (17, 18), a top wall (15), a base wall (16) and a front and rear (end) wall (12, 14). At least that portion (12?) of the housing wall, especially of an end wall (12), which is associated with the plate (21) has a smaller width than the plate (21). The latter is, in addition, mounted to allow its movement transversely to the longitudinal extent of the associated housing wall (12), or transversely to the insertion direction (11) of the cartridge (10) (double-headed arrow 24).

  • Publication number: 20070183372
    Abstract: Disclosed is a method which allows for a fast and efficient establishment of a connection between members of a group, more specifically between a mobile radio user who triggers the establishment of the connection and additional mobile radio users of a group of mobile radio users via at least one mobile radio network. According to the inventive method, a first channel that can be used for transmitting signaling data is set up when establishing the connection. User data, such as language, which is to be transmitted between the mobile radio user triggering the establishment of the connection and other members of the group is also transmitted via said channel in addition to the signaling data until a second channel is also set up for the connection, whereupon user data is transmitted via the second channel.

  • Patent number: 4798605
    Abstract: A device for continuously draining a pouch is adjustable for puncturing and draining the pouch. In certain embodiments, the device has an end portion capable of being affixed to a joint affixed to a pouch. An end-piece is connected with the affixing end portion by means for reciprocating the end-piece towards and away from the joint and pouch. A needle affixed to the end-piece extends towards the pipe and joint and has a length sufficient to penetrate through the joint to pierce the pouch when the end-piece is reciprocated towards the adjustable portion. A pipe is positioned relative to the end-piece for dispensing liquid flowing from a pierced pouch via the void from the joint to the end-piece.
