Abstract:
An installation for the hardened galvanization of a continuously-moving rolled steel strip, includes a coating tank receiving a liquid metal mixture containing, for example, zinc and aluminum to be deposited on the strip which is immersed in the mixture. The liquid mixture is permanently circulated between the coating tank and a preparation device, in which the temperature of the liquid mixture is deliberately lowered in order to reduce an iron solubility threshold and is sufficiently high for initiating fusion of at least one ingot containing a zinc-aluminum Zn—Al alloy in a so-called fusion zone of the preparation device, in an amount necessary to compensate for the liquid mixture used for deposition on the strip. The installation includes a loop for circulating the liquid mixture that is thermally optimized.
Abstract:
A mask frame assembly for depositing a thin film including at least two unit masks, ends of the unit masks being coupled to a frame having an opening, and each unit mask includes a plurality of deposition openings. A first gap has a width substantially equal to a width of the deposition openings and is located between the unit masks.
Abstract:
A hot melt adhesive system includes a melting unit configured to liquefy a bulk form of hot melt adhesive and deliver the liquefied hot melt adhesive to an application location. The melting unit includes a controller for establishing and/or verifying at least one system condition, such as temperatures associated with system operation. A machine reading unit is coupled with the controller and is capable of receiving information from a machine readable element and communicating the information to the controller for use in establishing and/or verifying the system condition. A method of operating the system includes scanning information on at least one system condition into the controller from a machine readable element, and using the scanned information during operation of the melting unit.
Abstract:
Process chamber shields having specially profiled edges exhibit increased lifetime in PVD and CVD deposition chambers. Edge profiling reduces flaking and delamination of materials deposited onto the shields, thereby prolonging shield life, and, consequently, reducing costs associated with deposition. In one embodiment, a shield having an edge portion terminating in a rounded tip, where the tip has high curvature and a small thickness, is provided. In another aspect, a shield having a concave portion connecting with an edge portion, where an upper (inner) surface of the edge portion forms a tangent plane to the upper (inner) concave surface of the concave surface, is provided. In yet another aspect, a shield with a tapered edge portion is provided. Shields, having profiled edges in accordance with these aspects and in accordance with combinations of these aspects, can better support deposited films, particularly films containing compressively stressed materials, such as metal nitrides.
Abstract:
Disclosed is a masking means for covering a section (12-3) of a steel sheet or iron sheet in a coating process, especially a section of a vehicle body or a housing of an appliance during a lacquering or preservation process. Said masking means is embodied as a quasi endless profiled member or injection-molded part (10-3) that is made primarily of plastic and is provided with a finely distributed magnetic or magnetizable admixture, particularly ferrite particles.
Abstract:
In an organic electroluminescent display device comprising a wiring layer, an insulating layer, a first electrode, an organic electroluminescent layer, and a second electrode, wiring which conducts with a second electrode is arranged between light emitting pixels, and is provided either between an organic electroluminescent layer and the second electrodes, or on top of the second electrodes.
Abstract:
A programmable material consolidation system includes a platen and an object release element on the platen. The object release element includes a lower surface configured to be secured to the platen and readily removed from the platen. An adhesive coating, which may cover at least a portion of the lower surface, may be formed from a material, such as a radiation-curable polymer, that is tacky when in an uncured state and not as tacky when in a substantially cured state. A nonstick coating on the platen may facilitate ready removal of the object release element therefrom. An upper surface of the object release element may include a material to which an object will adhere, but which may be readily removed from the object once fabrication thereof is complete.
Abstract:
The disclosure relates to a reusable spray shield that can be used in painting applications such as the painting of residential and commercial buildings to protect an object that is not to be painted from paint overspray or errant paint particles. The reusable spray shield includes a frame and a membrane. The membrane can be a flexible plastic sheet that is attached to the frame with a number of attachment devices, such as VELCRO® pads bonded to both the membrane and the frame. The membrane can be quickly removed and replaced. The used membrane can be disposed of with the paint supplies according to local disposal guidelines. In addition, the frame can be quickly put together and taken apart. The frame, in its component parts, permits the frame to be easily transported from one location to the next.
Abstract:
The invention relates to a device for removably fixing a mask in the form of a rectangular frame, on the legs of which clamping means are provided for gripping the end of the mask. According to the invention, the clamping means comprise a plurality of individual spring elements which grip closely adjacent points on the mask edge. The individual spring elements which are assigned to one leg of the frame and are embodied as leaf springs that are interconnected in a comb-type manner can be moved from a fitting position in which the frame can be fitted with the mask into a clamping position by means of a common auxiliary clamping member.
Abstract:
Masking means (1) for masking of a longitudinally extended edge area of a vehicle body or an appliance housing during a coating process, in particular a painting or preservation process, with the arrangement of a longitudinally continuous cavity and slot (3) of the outer contour leading into it, whose boundary areas are elastically pre-tensioned to each other.
