Abstract: The present invention relates generally to a new arrangement for surface mounting a polarized electrical component (e.g. tantalum capacitor) on a printed circuit board. Also described is that the electronic device is testable electrically to indicate both the proper mechanical mounting and the correct orientation of the electronic component on the printed circuit card. The arrangement comprises an electrical component having a first and second power connector leads and further having a test connector lead. The arrangement further includes a circuit board having a connector footprint having a first and second pads connected to supply rails on the printed circuit board and also a pair of test pads connected to first and second test points on the circuit card. Correct orientation of the component is indicated when the test lead is connected to a first of the test pads and one of the first or second power leads bridges between the second test pad and one of the pair of pads connected to the supply rails.

Abstract: The present invention provides an ink which contains a SERS--active metal aggregate containing a Raman active compound.

Abstract: A plastics composition comprising a high molecular weight material and an effective coloring amount of an azo pigment of formula ##STR1## where M is Mg, Ca, Sr, Ba or Mn or a mixture of two or more thereof, R.sup.1 and R.sup.2 are chlorine or methyl, x is zero or 1, y is zero or 1 and the sum of x and y is 1, with the proviso that when the high molecular weight material is polyvinyl chloride y is zero.

Abstract: The present invention provides a phthalocyanine of Formula (1): ##STR1## wherein: MPc is a phthalocyanine nucleus of Formula (2); ##STR2## in which M is a metal atom, a chloro-metal group, an oxy-metal group or hydrogenX is halogenR.sup.1 is an benzylamino or N-alkyl aminoalkylR.sup.2 is H or an optionally substituted alkyla has an average value from 15 to 8b has an average value from 1 to 8a+b is from 4 to 16.

Abstract: The invention provides a pigment composition comprising a pigment having adsorbed on its surface, or as a physical mixture, up to 10% by weight, based on the total weight of pigment composition of a coding compound which is a compound containing an azo, azomethine or polycyclic chromophore and which has an absorption spectrum and a Raman spectrum different from that of the pigment. The compositions are suitable for use in printing inks for security applications.

Abstract: The present invention provides a method of reducing the tendency of a resinated pigment product to self-heat which comprises treating an aqueous slurry of the pigment with a compound of a multivalent metal or metalloid under conditions such as will precipitate an insoluble compound of the metal or metalloid on the pigment, and then isolating the treated pigment.
