摘要:
Linear polycarbonate resin virtually free of surface defects that impair the suitability of the resin for demanding optical application is disclosed. Also disclosed is a process for the manufacture of the resin. The surface defects included in the resin are in the form of transparent fluorescing particles, the particle count of which portion that are 15 and 250 μm in size, is up to 1.8 counts/g, said count being determined by exciting the residue remaining after filtering a solution of said polycarbonate in methylene chloride through a Teflon filter of 5 μm pore size at a wavelength of 400-440 nm, 25× overall magnification and illumination time of 40 millisec. The polycarbonate is suitable for making films of improved optical properties.

摘要:
The invention relates to a packaging machine comprising a device for producing a deep-drawn plastic packaging tray and a welding device for welding a top foil to a packaging tray, wherein at least the packaging tray is made from a shrinkable plastic foil. A method for producing packages with the aid of at least one shrinkable foil is also disclosed.
摘要:
A multilayer composite material having at least one layer of (co)polycarbonate is disclosed. The (co)polycarbonate contains as end groups phenolate groups of formula (1) wherein R is selected from the group consisting of C10-C25-alkyl, C10-C25-alkoxy and C10-C25-alkyl-substituted aryl. The inventive composite material which may be transparent or colored, exhibits improved laminability and processability as compared with the prior art and may be laser-printable.
摘要:
The invention relates to a processing line for producing foods, such as sausage, ham or cheese. Said processing line comprises at least one processing device, a packaging device and transportation means. At least one partial area of the surface of the processing line has a permanently germ-free surface.
摘要:
A system and method for object state management. According to an embodiment of the invention, a status management runtime environment receives a request by an application object node to determine whether an action is allowed to be performed, makes a determination, pursuant to the request, as to whether the action is allowed to be performed based at least in part on status information associated with the application object node in a status repository, and sends the determination to the application object node in response to the request.
摘要:
A design-time status schema model describes the progress of a data object through a computing process. The status schema model includes status variables, processing actions and constraints for performing actions. The status schema model also may describe permitted changes to a status variable in response to performing an action. At runtime, the status schema model is used to control processing performed by, or on, an instance of a data object corresponding to the status schema model.
