Ultrasonic Coating Systems Offer Savings in Glass Nanocoating
Sono-Tek Corp. in Milton, N.Y., provides full solutions for depositing uniform nanolayers of solution onto float glass, architectural glass, solar glass, mirrors and other specialty and functional glass products.

Offered in several frequencies (allowing customization of drop size from 18-49 microns), the company’s non-clogging ultrasonic atomizing nozzle offers tight drop distribution, minimal overspray and compatibility with common nanosuspensions used in glass coating. Applications include low-E, anti-reflection/anti-glare, anti-stain, anti-static, photoresist, self-cleaning (nanophase), touch-screen (CNTs), solar cell compounds and other active/passive coatings. Multiple nozzles are configured for coating any width of glass.

The company’s WideTrack float glass coating system has many integrated features, including: no heat build-up despite the high temperatures associated with float glass production; pump control system that delivers repeatable flow to each nozzle; integrated air conditioning system that keeps electronics cooled; a control tower with real time monitoring and PLC control of all system functions via HMI interface; line speed encoder for continuous process monitoring; and on-the-fly optimization.

Bohle Helps Detect the Tin Side of Float Glass

The TinCheck tin side detector from Bohle America Inc. in Charlotte, N.C., is a compact device that allows fabricators and manufacturers of insulating glass to identify the tin side of float glass quickly and easily. By using the latest LED components, the TinCheck can graphically display the correct result after just one measurement. When the tin side is detected, a green diode lights up; the atmospheric side is indicated by a red diode. Color-blind customers can orient themselves by an acoustical signal that can be switched off.
inCheck has two work modes: the basic mode A setting presents its results based on stored reference measurements of sample lites of various glass manufacturers. In mode B, the user can make a comparison measurement (from both sides) of a reference lite to define a threshold value and store it in the tool.

New Sparklike Tool Spies on Glass
Spyglass, Sparklike’s new laser-based glass lite analyzer, handles all the different dimensions needed for analyzing flat glass, such as thickness and configuration of lites, as well as identifying coatings and PVB films. Just press the small device against any type of lite, push the button and in a matter of seconds all the characteristics of the glass are shown on its large display.

In addition to showing plain numbers on the display, Spyglass can show the structure of the measured glass graphically. There are no complex menus—users simply choose one of the four measuring functions, push the main button and let the laser-based measuring technology handle the rest.

The company says it’s battery-operated device is lightweight and fits in a pocket.

Unruh Fab Announces New Safety Feature
To increase its customers’ safety, Unruh Fab Inc. in Sedgwick, Kan., has added two rack-mounted inclinometers as standard equipment on all of its pickup racks and one on its single-sided van racks.

The inclinometers provide a distinct, easy-to-read visual reference that lets the driver know if the truck it is parked at an unsafe angle for loading or unloading. When truck lean exceeds 3 degrees, the driver should be alert to the fact that the glass may be in danger of falling. Large calibration markings on the inclinometers provide a clear visual indication to the driver of how much the truck is leaning so adjustments can be made to assure safe loading and unloading.

The company says that it can provide a simple-to-install kit containing one or two inclinometers, labels and mounting instructions for racks already in service.
