Abstract: A holder (10) for at least two lavatory-paper rolls positioned one above the other and consisting of a paper web wound up on a sleeve or a shaft, the holder having a first and a second wall which are arranged in parallel at a distance to one other, wherein each of the walls has a guide for receiving one end of the shaft or of a shaft journal that can be received in an opening in the sleeve. The guide has a feed portion running vertically, the feed portion merging into an unrolling portion running at an inclination with respect to the vertical towards at least one first tear-off element or a stop, wherein the gravitational force of the lower roll located in the unrolling portion causes the circumference of the roll to lie against the stop and the paper web can be unrolled through a removal opening.

Abstract: A holder (10) for at least two toilet-paper rolls (12, 14) which are arranged one above the other and consist of a paper web (56) wound up on a sleeve (52, 54) or a shaft, having a first and a second wall (28, 30) which are arranged at a distance parallel to each other, wherein each of the walls (28, 30) has a guide (40, 42) for receiving one end each of the shaft or of a shaft journal, which can be received in an opening in the sleeve, wherein the guide (40, 42) has a substantially vertically running supply portion (40b) for supplying a toilet-paper roll (12, 14), the supply portion merging into an unrolling portion (40c) running at an inclination with respect to the vertical in the direction of at least one first tear-off element (60, 62) or a stop (72).

Abstract: The invention relates to a device (10) for dispensing paper sections of predetermined length, with a device (26), which is operated by pulling on an end (74) of the paper web, and which separates the paper sections from the paper web (24) wound onto a paper roll (22) and provides easy manual access to the end (74) of the paper web that follows the separated paper section has been released.

Abstract: The invention relates to a device (10) to dispense paper sections of a predetermined length, comprising a device (26), operated by pulling on an end (74) of the paper web, for separating the paper sections from a paper web (24) wound onto a paper roll (22), and to provide easy manual access to the paper web (24) that follows after the separated paper section has been released, whereby the device (26) comprises at least one cutting roller (40) with a width that corresponds to at least the entire width of the paper web and a knife (42) that extends substantially over the entire side of the roller and protrudes rigidly from a roller shell, whereby associated with the cutting roller (40) is a pressure roller (44), which has a slit-shaped opening (46) that corresponds to the knife and is coupled to the cutting roller via geared wheels (52, 56; 54, 58).

Abstract: The invention relates to a device for separating paper sections (74) from a paper web wound onto a paper roll and for allowing easy manual access to the paper web that follows after the separated paper section, whereby the device comprises a cutting cylinder (40), which extends over at least the paper width, and a knife (42) that extends essentially over the entire roller width, whereby the knife (42) comprises a blade (114) and a series of teeth (120, 122, 124, 126), which are arranged spaced apart along the length of the blade, whereby the groups of teeth (120, 122, 124, 126) are separated from each other by cut-outs (128, 130, 132), and whereby the cutting roller (40) is associated with a pressure roller (44), which has a slit-shaped opening (46) and is coupled to the cutting roller (40).

Abstract: Methods and apparatus, including computer program products, for recommendations based on adoption curve. A method includes tracking over a period of time user popularity of a media content using a web service residing in a server, the popularity and period of time representing a life cycle of each of the media content. The method tracks over the period of time users enrolled in the web service and when in the period of time each of the users adopted the tracked media content and associates adopted media content with user profiles representing the users. The method recommends media content associated with a first user who adopted the tracked media content earlier in the period of time to a second user who may want to adopt the tracked media content subsequently in the period of time.
