An improved method for applying an electrically charged lubricant on an oppositely charged carcass trolley in a meat packing plant meeting the requirements of (1) adequate lubricity, (2) “drip-resistance,” (3) safety, (4) rust resistance, (5) economy of manufacture and use, and (6) the ability to be removed by cleaning methods is provided by preparing a mixture of mineral oil, a fatty acid, a silicone oil, and a polybutene, each being acceptable for incidental contact with food.

Described here is a method for determining the mean length of filaments formed on rotational atomization of a coating material composition, the method including atomization of the coating material composition by means of a rotational atomizer including as application element a bell cup capable of a rotation (1), optical capture of the filaments formed here at the bell cup edge, by means of at least one camera (2), and digital evaluation of the optical data obtained in this way, to give the mean filament length of those filaments formed on atomization that are located at the edge of the bell cup (3), as well as methods for compiling an electronic database and for screening coating material compositions when developing paint formulations.

Disclosed herein is a method for determining a drop size distribution within a spray and/or a homogeneity of this spray, the spray being formed on atomization of a coating material composition, which includes atomization of the coating material composition by means of an atomizer, the atomization producing a spray, optical capture of the drops of the spray formed, by a traversing optical measurement (2), and determination of at least one characteristic variable of the drop size distribution within the spray and/or of the homogeneity of the spray, on the basis of optical data obtained as per step (2). Also described herein are methods for compiling an electronic database and for screening coating material compositions when developing paint formulations, carried out on the basis of the method.

The first station includes at least one sensor configured to measure at least one value of a parameter of the atomizer when the atomizer is in the second position.

A handheld portable electrostatic device for electrostatically applying a treatment solution to a treatment site of a patient, including a housing and a cartridge removably disposed in the housing. The cartridge includes a cartridge housing and a nozzle for applying the treatment solution. An electrostatic module is provided to electrostatically charge and ionize molecules of the treatment solution of the cartridge. The treatment solution is configured to flow toward the nozzle whereby at least one electrode electrically connected to the electrostatic module physically contacts the treatment solution as it flows therethrough and applies an electrical charge to the treatment solution.

An air turbine drive spindle includes a rotary shaft, a bearing portion, a damper ring, a cover member, and at least one or more O rings. The bearing portion surrounds at least a portion of an outer circumferential surface of the rotary shaft.
