Abstract: A method for operating a network infrastructure-side network unit of a cell-based wireless communication network is provided. The method includes: receiving a scheduling request message for a sidelink channel in an unlicensed frequency range on an uplink channel by a roadside network unit, the scheduling request message indicating a size of the data available for transmission on the sidelink channel at the roadside network unit; ascertaining a scheduling grant message as a function of the size, the scheduling grant message including an assignment of a number of sidelink resources of the sidelink channel to the roadside network unit, and the assigned number of sidelink resources being sufficient to transmit the available data and additional data of other roadside network units; and transmitting the scheduling grant message to the roadside network unit on a downlink channel.

Abstract: A method for operating a network infrastructure-side network unit of a cell-based wireless communication network includes: predicting a piece of cell-related occupancy information of sidelink resources of a sidelink channel in an unlicensed frequency range; receiving a scheduling request message from a roadside network unit for the sidelink channel on an uplink channel; ascertaining a scheduling grant message for the roadside network unit based on the predicted cell-related occupancy information, the scheduling grant message including an assignment of at least one sidelink resource of the sidelink channel to the roadside network unit; and sending the scheduling grant information to the roadside network unit on a downlink channel.

Abstract: A condenser having a receiver for storing liquid refrigerant, the condenser having a heat exchanger block with at least one manifold and with a tube and fin block, wherein the tubes communicate with the at least one manifold for introducing and releasing refrigerant to or from the heat exchanger block. The receiver is located adjacent to one of the manifolds. The receiver has a tube with at least one open tube end and with at least one disc. The disc is located within the tube at the tube end in order to close the tube end and the disc is fluid tight connected with the tube end by cold metal transfer welding.

Abstract: A novel apparatus for an ion exchange system is provided. The apparatus comprises a first column for housing a first fluidized bed through which particles are flowed countercurrently to an ion-containing fluid to yield ion-loaded particles, a second column through which the ion-loaded particles are flowed countercurrently to an eluent fluid to yield regenerated particles, and a transport section which transfers the regenerated particles for re-introduction into the first column to repeat the ion exchange cycle in a continuous manner. A continuous method of ion exchange is also provided.

Abstract: The present invention relates to hair colouring kits and methods of use thereof which comprise an oxidative component, a colouring component, a conditioner component and a colour refresher component. The kits and methods of use thereof allow for the delivery of the required initial colour and shine to the hair but which further enable the maintenance of the colour over a longer time period without the need for an additional oxidative colouring event.

Abstract: A breathable, water resistant fabric comprising a reinforcing layer, a barrier layer applied to the reinforcing layer and a a breathable first protective layer covering at least a portion of the barrier layer. The reinforcing layer has a first side and a second side and includes a plurality of openings or passageways extending between its first and second sides to render the reinforcing layer breathable.

Abstract: A roofing underlayment for placement over a roof substrate prior to the application of shingles, tiles or other roofing materials. The underlayment comprises a sheeting material having an upper surface and a lower surface. The underlayment contains a grid that is visually identifiable from above the underlayment when the underlayment is received over the roof substrate with its lower surface adjacent to the roof substrate. The grid assists in the alignment of the underlayment with the roofing substrate during application of the underlayment to the substrate and further assists in the alignment of roofing materials applied over the underlayment.
