  • Patent number: 10999101
    Abstract: A controller node receives a list of a first plurality of flows programmed on a network switch. The controller node extracts a flow cookie value from a flow cookie data field of each flow in the first plurality of flows on the received list and calculates a session identifier on the basis of the extracted cookie values. At least one add flow command is transmitted from the controller node to the network switch to program a second plurality of flows on the network switch. The at least one add flow command comprises flow cookie values in the flow cookie data fields of each of the flows in the second plurality of flows which are set equal to the calculated session identifier. At least one delete flow command is transmitted from the controller node to the network switch to delete programming of the first plurality of flows on the network switch.

  • Patent number: 10948232
    Abstract: A method and a fiber-treatment system dry wet or damp fibers. A fiber mat (13) including wet or damp fibers is formed on a treatment band (31) which is moved in a conveying direction (x). An air flow (36, 36a) composed of heated drying air is generated in the fiber dryer (30). The heated drying air is guided in an upward direction through the treatment band and the fibers contained in the fibre mat (13, 14) are loosened and dried. Linters (16) possibly produced by any moving fibers are captured by a filter band (32) arranged above the treatment band, which is also moved in the conveying direction (x). At the outlet of the fiber dryer, the fibers are detached from a support (17) formed on the filter band, in particular when guiding the detached fibers back towards the dried fibers guided to the treatment band (31, 31c).

  • Patent number: 10927493
    Abstract: In a dryer, humidity of supply air in a supply path of a heat pump dryer unit is directly detected by a first humidity detection sensor, and humidity of exhaust air in a discharge path is directly detected by a second humidity detection sensor. The first and second humidity detection sensors are collectively installed at one place, and a first conduit or a second conduit that guides the supply air or the exhaust air to a position of the corresponding sensor is provided. The sensors may be collectively disposed at one place in the supply path or the discharge path. This facilitates mounting of the sensor and saves a mounting space. Because environment temperatures of the two humidity sensors can be regarded as equal to each other when using relative humidity sensors, temperature detection for conversion into absolute humidity can be performed at one place.

  • Patent number: 10914519
    Abstract: The invention relates to a method for drying salts with a water of crystallisation content in convective apparatuses that can additionally be indirectly heated. The invention is primarily characterised in that the drying process takes place with a moisture content of the drying gas above a determined level. The gas surrounding the salt particles during the drying process therefore has a specific humidity. In this way, the rate of drying is positively influenced.

  • Patent number: 10849400
    Abstract: The invention relates to hair dryers. Various techniques for improving air flow in hair dryers are described, including a hair dryer providing laminar flow air. In another variant a hair dryer has a two air flow channels: one a hot air channel the other a cool air channel, with the cool air channel circumscribing the hot air channel. The nozzle end of the hair dryer is arranged such that the cool air channel extends forward of the hot air channel outlet. This allows a hair dryer to be placed close to, or on, a person's hair/head without and risk of burning the person's head. A hair dryer with external power supply is also described which reduces the weight of the housing held by a user.

  • Patent number: 10820677
    Abstract: A hair dryer with an ionizing solution provides a translucent reservoir which contains an ionized solution. The hair dryer heats the solution into a vapor, and may then be used to apply the ionized vapor to a salon client's hair while styling it, to prevent brittleness, damage, and split ends. In one embodiment a cradle is provided for recharging a handheld hair dryer and storing various attachments which are ready for immediate use. When separated from the handheld hair dryer, the cradle transfers electric power to the hair dryer via resonant inductive coupling, creating an oscillating magnetic field which is converted to electric power by components within the hair dryer. A second embodiment provides a standing hair dryer. The hair dryer also provides wireless internet and power outlets for mobile electronic devices.
