Coatings, which act as barrier layers to inhibit migration of alkali metal ions from a glass surface and/or act as colour suppressing underlayers for overlying infra-red reflecting or electrically conducting layers, are deposited by pyrolysis of a gaseous mixture of a silane, an unsaturated hydrocarbon and carbon dioxide on a hot glass surface at a temperature of 600 DEG C to 750 DEG C.

PURPOSE:To improve the life characteristics remarkably without deteriorating the quick discharge characteristics by adding the fluororesin dispersion into the dilute sulfuric acid and immersing a paste type electrode into said dilute sulfuric acid. CONSTITUTION:The relationship between the cycle life and the quick discharge characteristics was investigated by changing the quantity of the fluorores...

The invention relates to a process for making a shaped part from sheet metal pieces (37,38) of different thicknesses. In the process flat sheet metal pieces (37,38) are butt welded at their cut edges by laser beam welding. Then the unit, welded together from a number of sheet metal pieces (37,38) of different thickness, are converted into a shaped part by pressing or deep drawing. Since the materi...

This invention relates to a process for preparing a rigid, closed-celled polyisocyanate-based foam in the presence of water and a blowing agent. The blowing agent comprises one or more organic compounds, particularly halocarbons, having a boiling point of from 222K to 272K at atmospheric pressure, and is substantially free of organic compounds having a boiling point of 273K or greater. Preferred h...

The present disclosure describes an apparatus and a method for detecting the presence of flaws in a moving sheet of material. The apparatus comprises a light source for projecting a light beam; a beam shaping unit for shaping the light beam into a predetermined structured light pattern, and projecting the structured light pattern onto a portion of the surface of the sheet; an optical unit for coll...

An automatic system for the inspection of surfaces of an object employing computer vision. The system examines the uniformity of the surface and adds it to the negative of an ideal mask, and then thresholds the result to determine if the object is defective or not. A binary image showing only the defects is generated by the system. The system ignores surface features, such as locating notches or m...

A two-rotor, three-position indicator for a valve actuator is connected to receive rotary input from at least two independently operating rotors connected inside the geared limit switch of a valve actuator. Individual drive lugs moved interconnected gearing to cause a pointer to indicate whether the valve stem is open, closed or in-between those two oppositely disposed limits.

In a dot serial printer suitable for bidirectional printing of enlarged letters and the like, a signal for starting printing is produced with a time delay of m/n times the dot drive period relative to a signal produced in synchronism with a motor control timing in advance of commencement of printing to thereby promote print quality of the enlarged letters and the like.

A method and system of radio data communications especially useful in communicating over a special communications channel between a base station or cell site of a cellular telephone system and one of many user stations. Each user station communicates an alarm condition which may be either a burglar type alarm or an environmental alarm to the base station by responding on a compelled basis to a sta...

In matrix printers, the printing elements in the printing head are frequently arranged so that they do not correspond to the printing raster of the characters to be printed so that the informations delivered for each time a printing column at the same time must be delayed a time. For this purpose, a delay device is assigned to each printing element of a matrix printer, the delay times for each dev...
