Rapid Ink-Charging Of A Dry Ink Discharge Nozzle

The present teachings relate to methods and apparatus for depositing one or more materials (e.g., one or more films, such as one or more solids) on one or more substrates, which may form part of an OLED or other type(s) of display. In some embodiments, the disclosure relates to apparatus and methods for depositing ink on one or more substrates. The apparatus can include, for example, one or more chambers for receiving ink, and plural orifices configured in the one or more chambers which are adapted for ejecting droplets of the ink; a discharge nozzle comprising an array of micro-pores (e.g., configured in a rectangular array), with each micro-pore having an inlet port and an outlet port, and the discharge nozzle receiving plural quantities (e.g., droplets) of ink from the chamber(s) via the orifices at the inlet ports and dispensing the ink from the outlet ports. The droplets of ink can be received at unique, spaced-apart locations on the inlet ports of the discharge nozzle. In some embodiments, a single liquid ink-holding chamber, which includes plural orifices (e.g., three), receives ink in liquid form having a plurality of suspended particles, and droplets of the ink are ejected substantially simultaneously from the chamber to respective, spaced-apart locations on the discharge nozzle; and the discharge nozzle evaporates the carrier liquid and deposits the solid particles on one or more substrates.

Escape-proof repeating animal trap

Repeating animal traps incorporating one or more inclined plane trap assemblies with means to preclude an animal on the tilting floor member of the trap assembly from engaging the top and/or side edges of the door member of the trap assembly in an attempt to escape from the trap by pulling the door member down to thereby unblock access to the entrance opening. Additional means are shown to preclude an animal within the enlarged holding chamber or enclosure of the repeating animal trap from engaging the inner end portions of the floor member in an attempt to escape from the trap by pulling the floor member down, enabling the animal to climb onto the floor member and then attempt to pull the door member down to escape from the trap. A barrier in the form of sharpened projections and/or an inclined ramp is provided beneath the inner end portions of the floor member to discourage an animal entering or nesting within that space when the floor member is raised in the reset position of the trap assembly. The barrier can include an inclined ramp whereby the space between the floor member and the ramp is decreased as an additional animal enters the trap assembly, to push an animal beneath the tilting floor member back into the enclosure. A plastic version of the repeating animal trap assembly enables thermoforming of many of the structural elements into the housing cover. Catches are also provided to selectively secure a glue board to the cover of the repeating animal trap to capture an animal attempting to bypass the entrance openings of the trap by running over the trap housing.

Portable filing case with retractable wheels and handle

A portable file case holder including a case housing having a rear wall, side walls, a top wall and a bottom wall for forming an interior compartment; the rear wall having an exterior wall surface and an interior wall surface; each of the side walls having an exterior wall surface and an interior wall surface; and each of the side interior wall surfaces include a plurality of paired, spaced-apart mounting receiving slots; and wherein each of the mounting receiving slots having U-shaped channels thereto for receiving the side edge of a shelving member. One or more of the shelving members for forming one or more compartments within the interior compartment of the case housing for receiving documents in the form of file folders, books, notebooks, 3-ring binders, manuscripts, transcripts, and/or computer print-outs. The case housing includes a detachable file case door having an exterior wall surface, an interior wall surface and a perimeter edging with a plurality of locking means thereon for covering the interior compartment. Each of the side exterior wall surfaces include a wheel receiving compartment; each of the wheel receiving compartments for receiving a tire wheel and wheel strut having a strut locking knob thereon. Each of the tire wheel and wheel strut having a first wheel retracted position within the wheel receiving compartment and a second wheel extended position extending from the wheel receiving compartment. The rear exterior wall surface includes a handle receiving compartment; the handle receiving compartment for receiving a case handle member having a handle locking knobs thereon; and the case handle member having a first handle retracted position within the handle receiving compartment and a second handle extended position extending from the handle receiving compartment.

Device for crushing ore through continuous discharge and method for crushing ore by using the same

InactiveCN104984807AImprove the efficiency of electric crushingReduce engineering difficultyGrain treatmentsElectricityLow voltage
The invention provides a device for crushing ore through continuous discharge and a method for crushing ore by using the same. A high-voltage discharge electrode partially stretches into a deionized water container, an insulating bush is arranged between the high-voltage discharge electrode and the deionized water container, the deionized water container contains deionized water, a low-voltage discharge electrode is fixedly arranged in the middle of the deionized water container, the low-voltage discharge electrode is provided with a holding chamber, the bottom surface of the holding chamber is provided with screen holes, the stretching portion of the high-voltage discharge electrode is aligned to the holding chamber on the low-voltage discharge electrode, and the upper end of the high-voltage discharge electrode is connected with the rotating shaft of a motor. The device for crushing ore through continuous discharge and the method for crushing ore by using the same have the beneficial effects that the crushing of ore through continuous discharge can be realized, the problem that discharge dead zones exist during electrode discharge is overcome, the electric crushing efficiency of ore is improved and the subsequent treatment difficulty of ore is reduced.
