  • Patent number: 9387986
    Abstract: The invention relates to the cargo area of an airport, having transporting paths which connect the land side and the air side of the airport and are intended for the standard loading units (ULDs), and also having interim stores for the buffer storage of the loading units prior to the cargo being assembled. In order to create storage and sorting opportunities in the immediate vicinity of the transporting paths, while being simultaneously independent of the main store, and in order to achieve flexible supply of the loading units, it is proposed for the transporting paths to be assigned vertical stores each with a plurality of storage levels which are arranged one above the other, are set up above or alongside the transporting paths and in which, with the aid of lifting means, the loading units, which can be lifted off from the transporting paths, can be stored.

  • Patent number: 6203480
    Abstract: Pressure processing roll with a roll jacket, the roll jacket rotatably mounted on a carrier by a bearing arrangement. The bearing arrangement has at least one hydrostatically supported bearing surface, which forms a gap with an opposing surface. A normal to the hydrostatically supported bearing surface, and therefore a normal force, has at least one axially oriented component. The bearing arrangement is acted upon by a predefined axially oriented force which substantially completely closes the gap in the absence of hydrostatic pressure in the hydrostatically supported bearing.

When using two stacks, each stack preferably has three to five rollers. At least one working nip has a dwell time of at least 0.1 ms. A heatable roller adjacent to the working nip is heated to a surface temperature of at least 100.degree. C. The roller stack is loaded such that an average compressive stress in the working nip is greater than or equal to 42 N/mm.sup.2.

  • Patent number: 5671665
    Abstract: A calender for treating a paper web includes a roller stack being loaded with a load on one end. The calender has at least two hard rollers each having a substantially smooth outer surface. The at least two hard rollers each have a device for heating a surface of the roller to a temperature of at least 100.degree. C. The calender also includes at least two soft rollers, wherein each of the at least two soft rollers is disposed adjacent to at least one of the at least two hard rollers to form a working nip therebetween. At least one working nip has a dwell time of the paper web passing through the working nip of at least 0.1 ms. The load on the rollers produces an average compressive stress in the at least one working nip of at least 42 N/mm.sup.2. An arithmetic mean of the numerical value of the surface temperature T, the dwell time t and the compressive stress p in all of the working nips satisfies the following relationship:a target value Zg=1.378-0.00356.multidot.T-(0.00825-5.12.multidot.10.sup.-5 T)p-?0.

  • Patent number: 5443000
    Abstract: A calender arrangement having vertically-arranged upper, center and lower rollers with matching upper, center and lower carrier-blocks and a suspended spindle, comprises a support element above a bearing-surface on the upper carrier-block. The support-element aids in lifting the suspended spindle and a carrier-nut when raising the upper carrier-block. An insert is placed between a bearing-surface on the upper carrier-block and the support-element, which comprises a horizontal slider seated on the upper carrier-block, which enables a relatively small motor to be used to reset the carrier-nut.
