  • Patent number: 10384855
    Abstract: An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.

  • Patent number: 10356668
    Abstract: Methods, nodes, computer programs and a mobile network for handling a terminating circuit switched signaling service to a terminal in a mobile network are described. A method of handling a terminating circuit switched signaling service to a terminal in a mobile network is described. The signaling service is distinct from a call. The mobile network comprises a first control node and a second control node. The method is performed by the first control node. The method comprises receiving signaling information for terminating the circuit switched signaling service to the terminal, subsequent to the step of receiving, detecting that the terminal has requested a location update from a second control node of the mobile network, and, based on the step of detecting, forwarding the received signaling information to the second control node.

  • Publication number: 20160331003
    Abstract: A method for preserving food. The food is heated in a moist state in a container, which has a venting opening and is suited as transport and retail packaging, by way of microwaves (M) for a limited time, however at least until hot steam (D) from in the container and exists through the venting opening. After the heating has ended, a gas (G) is injected into the container using a cannula, and a container wall made of plastic film is pierced with the cannula. The plastic film that is used has a thickness of less than 100 ?m. At least one layer of the plastic film is made of polyethylene terephthalate having a thickness of greater than 19 ?m.

  • Patent number: 9421590
    Abstract: The invention relates to a sealing device for installation in a roll arrangement between the roll journals of a roll and chock. The sealing device has an annular main body having sealing rims that extend radially outwards. Furthermore, the sealing device has an annular reinforcement element having a strip-like section which coaxially surrounds the main body on the outer side thereof. In order to ensure the dimensional stability and thus also the function of the sealing device even after the installation thereof in the roll arrangement, that is to say after said sealing device has been pushed onto the frustroconical roll journals, the reinforcement element according to the invention has, in addition to the coaxial strip-like section, at least one flange which is connected thereto and is connected to the sealing rim. Furthermore, the invention relates to said roll arrangement.

  • Patent number: 9339857
    Abstract: The invention relates to a roll arrangement for use in metallurgical technology, comprising a roll that has a roll barrel and two roll necks, and at least one neck bushing for accommodating at least one of the roll necks in a rotationally fixed manner. A carrier element that functions as a form-locking rotationally fixed connection is arranged between the roll neck and the neck bushing. In order to increase the load-bearing capacity of the roll bearing without increasing the size of or the mounting space for the roll bearing and at the same time ensure easy assembly, the roll neck is mounted in the neck bushing with some radial play such that a circumferential cavity is formed between the neck bushing and the roll neck in the unloaded stated as a result of the radial play. In order to increase the size of the cavity, the roll neck or the inner surface of the neck bushing additionally has a concave contour or profile.

  • Patent number: 9132516
    Abstract: The invention relates to a method for preparing a bearing arrangement for a roll journal, wherein the bearing arrangement comprises a bearing insert, with a bearing bush, and a journal bush which is mounted with bearing play in the bearing bush and can be pushed onto the roll journal. In order to extend the service life of the bearing arrangement and therefore to save costs, the method according to the invention provides, in order to eliminate scoring, for the external diameter Da of the journal bush also to be reduced below a threshold value Dak and at the same time for a novel bearing bush to be supplied which, with regard to its internal diameter Di new, is adapted to the reduced external diameter of the bearing bush in such a way that the bearing play remains within a predefined permissible value range.
