Abstract: Abstract of the Disclosure A conductive copper paste composition adapted to yield a highly conductive film receptive to solders without pretreatment is disclosed.  This conductive paste comprises a copper metal powder, a resin component including a thermosetting resin, and an assortment of additives.  In use, the paste is applied to an insulation substrate to a predetermined circuit pattern and cured in situ.  Soldering can then be performed directly on the cured circuit.

Granted: 1992-10-06
Abstract: TITLE:  Pyrotechnic Train ABSTRACT:  (re. Figure 2) A micro pyrotechnic train is formed from a reactive laminate comprised by a plurality of thin films of an electron donor material (9) and an electron acceptor material  (10) alternately layered upon a substrate layer by vacuum deposition.  The thus deposited films are then removed from selected areas by etching, using standard printed circuit  board techniques,  to leave a desired network of  reaction progression paths (2).  The thickness of the films is of substantially molecular order to maximise molecular intermingling between them, and the  number  of  films  is  selected  to  ensure  a  reliable  burning characteristic.  Ignition of  the  conjoint  films  at  any  selected location  initiates  a  self-sustaining  exothermic  reaction  which progresses laterally along the film interfaces.     In further aspects  the reactive laminate is applicable as an infra-red emitting coating and as a flash transmitter.  It is also applicable as a bridge igniter,  the laminate being employed as an electrode bridge in place of a conventional exploding bridge wire.

To facilitate the reloading process, the take-up spool core is mounted in the housing on a bearing pin which extends upward from a contact surface.  The take-up spool core has a bearing bore into which the bearing pin extends and a bearing surface which rests on the contact surface.  The contact surface is disposed closely below a receiving bore in the take-up spool core which accommodates a fastening element attached to the end of the ribbon.
