摘要:
A transfer belt for carrying a fibrous web and a papermaking or similar machine. The transfer belt consists of a supporting substrate of a polymer foam and a reinforcement layer of aramid or glass fiber in either fabric or layer foam and a release layer that overlies and is bonded to the supporting substrate. The release layer is formed from a material promoting release of the fibrous web. The release layer may be selected from a variety of materials. The layers each contribute their own function to the operation of the belt to provide superior performance.

This invention relates to a machine for the production of a paper web, paperboard web or tissue web, having a roller with a circumferential surface and having an endless belt, in particular a transfer belt, which is wrapped around the circumferential surface of the roller in sections and has a bottom side which in the wrap zone can be brought into contact with the circumferential surface, as the result of which the endless belt and/or the roller provide a storage capacity suitable for accommodating at least in part the fluid which gets into the wrap zone between the bottom side and the circumferential surface.

The invention relates to a gantry system for a particle therapy facility, having a beam guidance gantry which has elements for beam guidance, and having a measurement gantry which has a device for beam monitoring. The measurement gantry and beam guidance gantry are thus of a mutually independent design and are, in particular, arranged in a mutually concentric manner. A gantry system of this kind is inter alia less susceptible to mechanical deviations during rotation of the beam guidance gantry.

The invention relates to an enzyme electrode which can be sterilized and regenerated and which has a sensitive surface and an enzyme in contact therewith. A semipermeable membrane is arranged at a distance from the sensitive surface of the detecting electrode and defines a chamber containing the enzyme which is supplied to and discharged from the chamber through a supply conduit and a discharge conduit, respectively. A sterilization device for the enzyme is arranged in the supply conduit for the enzyme. The enzyme electrode is produced by means of the detecting electrode being sterilized in a manner known per se and by means of the enzyme being led into a chamber via a sterilization device through a supply conduit for contact with the sensitive surface of the detecting electrode and for contact with the semipermeable membrane arranged at a distance from said sensitive surface. The enzyme is continuously or intermittently supplied through the supply conduit simultaneously as previously supplied enzyme is discharged from the chamber through the discharge conduit.
摘要:
A system for computer assisted monitoring of a cross profile of a quality parameter of a material web, especially a paper or cardboard web during its production and/or conversion, which includes a measuring system for measuring the cross profile, at least one computer based operations and logic unit for the determination of the standard deviations of at least two interference profiles that are representative for different interferences in the form of different peak groups in the measured cross profile. The different peak groups differentiate in that their peaks have different width ranges. Elements for storage, display and/or further processing of the determined standard deviations are also included.
摘要:
In a closed system for collecting and retransfusing autologous blood having a collecting vessel (4) to receive the blood and an anticoagulant fluid, as well as a retransfusion line (14, 14') containing a microfilter, through which at least a portion of the blood collected in the collecting vessel (4) is retransfused, the inlet for the anticoagulant fluid is provided, preferably between the collecting vessel (4) in which a negative pressure can be maintained and a drain (2) or the open end of a drain tube. The collecting vessel (4) is connected with a collecting and separating container (13, 13') by means of a tube line (10, 10'), to which a tube pump (11) can be applied. The retransfusion line (14, 14') for the erythrocyte concentrate deposited in the collecting and separating container (13, 13') is connected to the outlet thereof.
摘要:
An air permeable sun shading fabric for provision of shade while allowing air to permeate the fabric includes a panel that is flexible and comprises a plurality of layers. The plurality of layers comprises an inner layer and an outer layer. Each of the layers has a plurality of openings. The openings are consistently sized and equally spaced, thus defining a band around each of the openings. The opening and a respective one of the bands define a unit. The openings of each of the layers are positioned in rows that are parallel. Each of the rows is offset by one half of the unit from adjacent rows. The layers are mutually coupled, such that each of the pluralities of openings is offset from the pluralities of openings positioned in adjacent layers.
