Abstract:
An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates “on demand” for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.

Abstract:
An automatic coating device uses a driving motor and a conveyer to form a cyclically rotating module. An injector filled with a coating material is disposed on one side of the conveyer. When an object to be coated is disposed on the other side of the moving conveyer, the coating material is then applied onto the object by the injector. This can increase the coating speed and quality.
Abstract:
An apparatus for producing a laminated object, includes a powder layer forming unit for forming a powder layer of a powdery material, a material supply unit for feeding the powdery material to the powder layer forming unit; and a solidified layer forming unit for forming a solidified layer by irradiating a light beam on a specified portion of the powder layer and sintering or melting the specified portion of the powder layer. The apparatus is configured to produce an integrally laminated three-dimensional object by repeating formation of the powder layer and formation of the solidified layer. The material supply unit includes a cartridge unit charged with the powdery material, the cartridge unit being configured to allow the powdery material to drop downwards.
Abstract:
A dosing device for the application of a coating mix (6) onto a running web, in particular a paper or paperboard web (1), which device comprises a rod (8) that is supported revolvingly over its entire length in a rod cradle (12), and a pressing device (13) acting on the rod cradle and producing a pressure of the rod onto the web (1) and onto the holding-on device (2, 17, 15) of the web, the rod (8) being provided with a wear resistant surface coating (15) with a hardness of about 10 to about 100 according to Shore A. The invention also relates to methods of using said rod, and to said revolving rod.
Abstract:
Device for pumping viscous materials, particularly sealant and grease, without dripping and method of the same are characterized by storing a predetermined portion of the driving energy in form of an angular and/or linear displacement of a torsional spring. This very portion of the stored energy will be released at the end of the operation when the operator let go the trigger, whereby the released energy will drive the final transmission and the end part of the final transmission to move backwards for a predetermined amount of displacement. This backwards movement of the end part of the final transmission causes the volume of viscous material to expand suddenly; this expansion of the volume of viscous material compensates the compression of the viscous material from the dispensing process, which will also draw back the viscous material on its way outward for to work and for to drip.
Abstract:
A spreading apparatus is provided for spreading flowable materials such as adhesives and/or sealants on a surface such as a floor and/or a wall. The apparatus has a pad retainer for retaining a removable spreader pad and a reservoir chamber for flowable material pivotally attached to the pad retainer to permit pivoting of the reservoir chamber frontwards and backwards. The reservoir chamber has an adjustable gate through which the flowable material may exit. The gate is proximal the bottom of the reservoir chamber and complementary to the width of the pad retaining means to permit more uniform spreading of the flowable material. A handle is attached to and extends from the reservoir chamber. The handle may pivot from side to side on the reservoir chamber and may be hollow to house a cable associated with the means for opening the gate. A system is also provided involving the spreading apparatus together with a removable spreader pad and a container containing the flowable material. The container is housed in the reservoir chamber and cooperates with the gate to permit the flowable material to exit the container and the reservoir chamber when the gate is open. The spreader pad comprises an elongated resilient foam member sufficiently thick to fit within and frictionally engage the pad retainer, and sufficiently high to extend below the pad retainer so that the spreader pad rather than the pad retainer contacts the surface when the spreader pad is retained by the pad retainer.
Abstract:
A method and device for coating of the face of a roll in a film size press with a coating agent by a coating device including a coating doctor that extends across the machine width and is loaded against the face of a roll in the film size press. The coating doctor spreads and smooths the coating agent, which has been introduced into the coating device and applied as a film onto the roll face before the coating doctor in the direction of rotation of the roll. To prevent the formation of streaks in the coating-agent film, in particular of streaks resulting from cavitation, adhesion of coating agent from the coating-agent film to the trailing side of the coating doctor is prevented by keeping the trailing side of the coating doctor moist or wet. Adhering of coating agent to the trailing edge of the coating blade is prevented by feeding a moistening medium as a constant flow to the area of the trailing edge. The moistening medium is introduced into the area of the trailing edge of the coating blade by spraying or atomizing.
Abstract:
An improvement in the preparation of printed circuits comprises inserting a deformable layer between the phototool or support layer, and the solder mask. The deformable layer provides a uniform, integral and relatively thin coating of solder mask over circuit components, and results in higher-quality solder joints and lower rejection rates for finished boards.
Abstract:
An apparatus for the preparation of a printing plate comprising a layer of photo-sensitive liquid resin, wherein the improvement comprises an application means for laminating an anti-wrinkle plastic sheet on the resin surface upon being doctored and at the same speed with that of the doctor.
