Abstract:
The present disclosure relates to methods and system for disinfecting surfaces within an area by forming peracids in a reaction layer in situ on the surfaces to be disinfected. Aqueous compositions comprising peracid reactant compounds, particularly hydrogen peroxide and acetic acid, are sequentially dispersed into the area, preventing peracids from being formed until the two peracid reactant compounds contact each other on the surface to be disinfected. Additionally, aqueous compositions containing peracid reactant compounds can further comprise ethanol to both decrease the surface tension of the droplets and enhance the reactants' biocidal activity. Peracid reactant compounds can be sequentially dispersed as electrostatically-charged droplets, so that droplets of a first aqueous composition containing at least one peracid reactant compound are dispersed with a polarity opposite that of a subsequently-applied second aqueous composition containing at least one peracid reactant compound, driving formation of a peracid on the surface in situ.
Abstract:
A method of applying particles to a backing having a make layer on one of the backing's opposed major surfaces. The method including the steps of: supporting the particles on a feeding member having a feeding surface such that the particles settle into one or more layers on the feeding surface; the feeding surface and the backing being arranged in a non-parallel manner; and translating the particles from the feeding surface to the backing and attaching the particles to the make layer by an electrostatic force.
Abstract:
Methods that allow independently applied pressures to a BGE reservoir and a sample reservoir for pressure-driven injection that can inject a discrete sample plug into a separation channel that does not require voltage applied to the sample reservoir and can allow for in-channel focusing methods to be used. The methods are particularly suitable for use with a mass spectrometer.

A method for forming a phosphor material on a surface of a target is provided, which includes the steps of: providing a chamber for receiving the phosphor material constituted by a plurality of particles, wherein a grid is disposed on or beneath a surface constituted by the phosphor material in the chamber, and the grid has a plurality of fine lines SN each having opposite first and second ends, N being a positive integer greater than 1; exposing the surface of the target to the phosphor material; and creating a charge on the plurality of particles, generating an electric field between the chamber and the surface of the target and oscillating the plurality of fine lines, so as to drive the plurality of particles toward the surface of the target and to be deposited on the surface of the target.
Abstract:
It is an object of the present invention to provide a method for uniformly forming a film on an outer circumferential portion of a metal automotive part by preventing penetration of a coating substance into a portion thereof unnecessary to be coated with paint. The method for producing a columnar or cylindrical metal automotive part whose outer circumferential surface includes a portion to be coated with paint and a portion to be uncoated therewith includes the following processes: (1) a process of providing a convergent nozzle-shaped covering jig which covers an outer circumferential surface of the columnar or cylindrical part at an axial end thereof and covers the portion to be uncoated with the paint, with a gap formed between the covering jig and the outer circumferential surface of the part; (2) a process of discharging a gas from the gap toward an end of a nozzle of the covering jig with the columnar or cylindrical part being rotated; (3) a process of sticking a film-forming substance to the columnar or cylindrical part from an axial side surface thereof.
Abstract:
Femtoliter to milliliter volumes of one or a plurality of different fluids of varied properties, semisolids or solids are energized electrically in an inductive or optionally an inductive-conductive manner, with one or a plurality of either analogue or digital energy sources of uni or multi-polar nature using high or optionally low DC, AC or RF voltage or energy supplies in programmed, coordinated manner with other devices (e.g., pumps or all types, syringes, pipettes, capillaries, scientific instruments, etc.) using special hardware to energize and direct matter from gaussian surfaces or multiple nested gaussian surfaces to produce and optionally fly drops or optionally sprays, to targets of all types, yielding matter directed with high precision and accuracy in volumetric, spatial and temporal terms, as the matter is optionally treated, measured, metered via current, optical, thermal or other measurement technologies with feedback, one or N channels at a time creating a digital record.
Abstract:
Various embodiments of the present disclosure provide a grounding apparatus for use with a spray device associated with a vehicle. The grounding apparatus is biased toward the ground so that a portion of the grounding apparatus makes contact with the ground even in uneven terrain. The grounding apparatus is configured to be mounted in a receiver portion of a trailer hitch. In addition, provided herein is a system for powering a spray device with a DC power source, such as an automotive battery. The system includes an oscillator coupled to a step up transformer.
Abstract:
The inventions disclosed by this application are for a cladding apparatus, a cladding head, and a method of cladding a relatively planar solid object such as a boiler waterwall. Cladding of non-horizontal surfaces is complicated by the effects of gravity as melted clad material trends to runoff the surface before the cladding material bonds to the appropriate location. The disclosed inventions overcome these limitations by controlling the relative angle of application by either rotating the workpiece or the cladding head through a pre-programmed sequence. Also presented in a compact design for a laser cladding head that facilitates such cladding by minimizing movement of the laser fiber and improves cladding speed over irregular shaped objects.
Abstract:
There is disclosed an apparatus for spraying and patterning, using an electrostatic force, includes a nozzle to which a voltage is applied to exhaust ink, a droplet circulation chamber provided in one end of the nozzle, with a hole provided in one end to spray the ink exhausted from the nozzle based on a particle size of the droplet and to temporarily collect the not-sprayed ink, and a substrate for impacting the ink sprayed from the hole thereon by forming an electric field between the nozzle and the substrate.
Abstract:
The invention relates to a method of aligning magnetic flakes, which includes: coating a substrate with a carrier having the flakes dispersed therein, moving the substrate in a magnetic field so as to align the flakes along force lines of the magnetic field in the absence of an effect from a solidifying means, and at least partially solidifying the carrier using a solidifying means while further moving the substrate in the magnetic field so as to secure the magnetic flakes in the carrier while the magnetic field maintains alignment of the magnetic flakes. An apparatus is provided, which has a belt for moving a substrate along a magnet assembly for aligning magnetic flakes. The apparatus also includes a solidifying means, such as a UV- or e-beam source, and a cover above a portion of the magnet assembly for protecting the flakes from the effect of the solidifying means.
