Method and apparatus are disclosed for drywall banjo apparatus for applying joint tape. An example tool for applying joint tape to a corner drywall joint includes a base and a wheel configured to rotatably couple to the base and roll along the corner drywall joint. The wheel includes a body that defines an outer surface. The outer surface includes a first angled surface configured to press the joint tape against a first drywall defining the corner drywall joint, a second angled surface opposite the first angled surface and configured to press the joint tape against a second drywall defining the corner drywall joint, and a rounded vertex defined between the first angled surface and the second angled surface. The rounded vertex is rounded to deter the wheel from perforating the joint tape.

Method and apparatus are disclosed for drywall banjo tools for applying joint tape. An example drywall banjo for applying joint tape includes a banjo body. The banjo body includes a panel and side walls protruding from outer edges of the panel to define a cavity that is configured to contain joint compound mud. The side walls include a first side wall that extends between an inlet and an outlet. The example disclosed drywall banjo also includes a sloped mound configured to couple to and project away from the first side wall within the cavity. The sloped mound is configured to guide the joint compound mud within the cavity toward the joint tape travelling between the inlet and the outlet to enable the joint compound mud to uniformly collect on a side of the joint tape.

Method and apparatus are disclosed for drywall banjo tools for applying joint tape. An example tool for applying joint tape includes a base configured to couple to a drywall banjo that dispenses the joint tape. The example tool includes an arm including a proximal end and a distal end opposite the proximal end. The proximal end is rotatably coupled to the base to enable the arm to rotate between an extended position and a retracted position. The example tool includes a corner wheel rotatably coupled to the distal end of the arm to enable the corner wheel to apply the joint tape along a corner drywall joint when the arm is in the extended position. The example tool includes side wheels rotatably coupled to the base to enable the side wheels to apply the joint tape along a flat drywall joint when the arm is in the retracted position.

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.

An apparatus for fabricating one or more electrowetting display devices, wherein the apparatus comprises a fluid dispenser to dispense fluids onto a substrate. The fluid dispenser comprises a first nozzle to dispense a first fluid of the fluids onto the substrate. The fluid dispenser further comprises two or more additional nozzles. Each additional nozzle dispenses a fluid in communication with the first fluid. The fluids dispensed by the additional nozzles combine to form a single second fluid that is substantially immiscible with the first fluid.

A holding unit holds label paper conveyed from a label printer that ejects ink onto the label paper. A peeling unit is disposed to the label paper conveyance path downstream from the holding unit, and peels labels from the liner of the label paper. The peeling unit can move bidirectionally between a start peeling position and an end peeling position. A peeling member folds back only the liner portion of the label paper. A peeling conveyance roller disposed downstream from the peeling member on the label paper conveyance path conveys the label paper. The peeling member moves from the start peeling position to the end peeling position by being pushed by the label paper conveyed by the peeling conveyance roller while the label paper is still held by the holding unit.
