Dry developer composition in powder form for use in penetrant inspection of surface flaws in bodies, consisting essentially of alumina, silica, talc and titanium dioxide. The resulting powder developer is particularly effective when applied to a surface following application of a fluorescent penetrant, to provide bright fluorescent indication of surface flaws when inspected under fluorescent illumination.

A method for positioning an indicium for printing on substrate. The indicium can be an IBIP type indicium and the substrate can be the surface of an envelope. The substrate has printable and complementary unprintable areas and a reserved clear area where printing is possible but unacceptable. The unprintable area is determined as function of printer characteristics and substrate dimensions. If the indicium overlaps the reserved clear area the indicium is modified by shifting portions of the indi...

This invention discloses mixed salts of aluminum having the empirical formula ##SPC1## Wherein R is an organic acid radical of from 7 to 20 carbon atoms, and n has an average value of from 0.5 to 2.5. The compounds of the above description are useful as herbicides.

A rapidly rotatable piercing tool for forming, substantially by frictional heat and pressure, a bossed hole in a metal plate or tube wall, said tool comprising a head of greater diameter, whereby a shoulder facing the leading end of the tool is formed for so shaping one of the end faces of the boss surrounding the hole, as to round off, to bevel off or to deepen said end face towards the hole in an annular region bordering the hole.

A trifluoromethanesulfonanilide compound having the formula: ##STR1## wherein Y is a (1-cyano-2-propyl)cyclopropyl group or a (1-cyano)cyclopentyl group.

A trifluoromethanesulfonanilide compound having the formula: ##STR1## wherein each of R.sup.1 and R.sup.2 is a lower alkyl group, X is a halogen atom or a trifluoromethyl group, n is an integer of 0 to 2, and R.sup.1 and R.sup.2 may form, together with the adjacent carbon atom, a ring which may be substituted by a lower alkyl group.

A postage printing system includes a transport device for feeding an envelope in a path of travel through the postage printing system, a printer for printing a postal indicia and an ad slogan on the envelope, and a control system in operative communication with the transport device and the printer. The control system obtains an indication from an operator of a selected print location for the ad slogan and determines if the postal indicia and the ad slogan may be printed in a single pass through ...

A method and apparatus for printing an information-based indicia program (IBIP) postage in a computer printing subsystem is disclosed wherein a third-party word processing software with mail merge capabilities generates text and a matching address as the input for a client application in high-volume document processing and mail systems without programmatically altering the word processing program to accommodate the printing subsystem. Addresses are validated and corrected in the printing subsyst...

A bubble making device which is powered solely by the wind or forced air, the device having a fan which is rotated by the wind which in turns operates a pumping assembly to deliver bubble forming fluid to a plural number of rotating wands, the wands also being rotated by the rotation of the fan. The bubble forming fluid is applied directly to the wands by a brush or wiper applicator, and any excess fluid is recaptured and returned into the main receptacle. The device is light-weight and virtuall...

Control apparatus and a method for providing fabricating apparatus of the type employed with structural members, with an automated operating cycle, where various tool means at one or more tooling stations required for the fabrication of the structural members are actuated automatically. The apparatus utilizes a programming template formed from a thin, flexible metal ribbon that is coiled about a stationary reel, having a free end thereof fixed with regard to a structural member that is moving re...
