摘要:
A layer stack for the surface coating of transparent substrates, in particular panes of glass, has at least one metal oxide composite layer produced by reactive cathodic sputtering and contains Zn oxide and Sn oxide. Relative to the total amount of metal, this metal oxide composite layer contains from 0.5 to 6.5% by weight of one or more of the elements Al, Ga, In, B, Y, La, Ge, Si, P, As, Sb, Bi, Ce, Ti, Zr, Nb and Ta. In a layer stack which has a silver layer as a functional layer, the metal oxide composite layer may be used as an upper and/or lower antireflection layer, as a diffusion barrier layer, as a sublayer of an antireflection layer and/or as an upper cover layer.

An apparatus and a process for making semi-finished products in the form of thin metal bars having a width-gauge ratio of over 60 and a maximum sheet metal gauge tolerance of 2%. A metal profile is fed continuously and upwardly through a pool of melt material having the same composition as the metal profile so as to form a coated metal profile. The metal profile is fed at a rate which would result in a coated metal profile having a thickness of at least three times that of the uncoated metal profile. The coated metal profile is subjected to a smoothing pass between a pair of smoothing rolls when the mean temperature in the crystallized layer of the coated metal profile meets a given condition. The smoothing rolls are adjustably disposed inside a housing at a distance of 0.5 to 5 m from the melt pool surface.

An ink ribbon cartridge for use in an office machine includes a housing; a ribbon; a supply reel for storing unused ribbon wound thereon and a take-up reel for storing used ribbon wound thereon, a drive roller rotatably supported in the housing; and an arrangement for resiliently urging the drive roller and the ribbon wound on the take-up reel into a peripheral, torque-transmitting contact with one another. The drive roller is arranged for being drivingly engaged by an advancing mechanism of the office machine when the cartridge is in place, whereby the drive roller imparts a rotation to the take-up reel in a winding direction for pulling the ribbon off the supply reel, for moving the ribbon through a printing station of the office machine and for winding the ribbon on the take-reel. There is further provided a reverse winding arrangement for pulling ribbon off the take-up reel and for winding the ribbon on the supply reel. The reverse winding arrangement includes a device for permitting the application of a winding torque to the supply reel; and a device for preventing blockage of the take-up reel by the drive roller in a direction opposite the winding direction.

An apparatus for separating a mixture of heavy particulate material and light particulate material into separate fractions of heavy and light material is disclosed. The mixture is introduced to a first separating means, particularly an air jig, with a vibratory carrier for separating the mixture into a clean light fraction and a heavy fraction, which heavy fraction contains some light material. The heavy fraction is passed to a second separating means, this second separating means being a pneumatic table associated with the vibratory carrier for separating the said heavy fraction into a clean fraction of heavier particles and a mixture of lighter particles with some small heavier particles, which mixture is directed to a conveyor for recycling through the air jig. The apparatus provides for a very clean separation of heavy particulate material and light particulate material at a high throughput rate.DESCRIPTION
摘要:
A multilayer film, capable of withstanding high thermal stresses, with silver as functional layer, a sacrificial metal layer placed on top of the silver layer and antireflection dielectric layers, has a metal nitride layer between the silver layer and the sacrificial metal layer. This metal nitride layer is composed in particular of Si3N4 and/or AlN and constitutes an effective diffusion barrier. The optical and energy properties of the silver layer consequently remain, for the most part, preserved, even after undergoing high thermal stresses (for example of the bending or toughening type when curving and/or prestressing a window pane provided with the multilayer film).

摘要:
A low-emissivity multilayer system, capable of being bent and prestressed, for glazing panes, with silver as functional layer, comprises a sacrificial metal layer of Ti or an alloy of Ti and Zn and/or Al placed above the silver layer, antireflection dielectric layers and an oxide, nitride or oxynitride covering layer. The sacrificial metal layer contains chemically bonded hydrogen. An optionally Al- and/or In-doped ZnO layer is adjacent to the sacrificial metal layer. The covering layer consists of a titanium compound. Multilayer systems of this type can be manufactured relatively inexpensively and have a high hardness and a high chemical resistance. Their color parameters are very reproducible, even in the case of a heat treatment at high temperature.
