Abstract: An improved combination air sanitizer, soft surface sanitizer, soft surface deodorizer and hard surface disinfectant is disclosed. The preferred active ingredient for the air sanitization and soft surface odor treatment functions is triethylene glycol (TEG). The preferred active ingredient for soft surface sanitization and hard surface disinfection functions is a mixture of various alkyl dimethyl benzyl ammonium saccharinates. The formulation may be provided in an aerosol spray form and is useful for sanitizing and removing bacteria and malodorant molecules from the air as well as disinfecting hard surfaces. A unique combination of corrosion inhibitors is disclosed for convention steel or tin-plated steel cans. A single produce can be used as an air sanitizer/air freshener, a soft surface sanitizer, a soft-surface odor remover/reducer and, a hard surface disinfectant.

Abstract: Printed circuit boards 10 having connector terminals 14 and 16 overlaying contact pads 17 and 18 are loaded into fixtures 22 which are conveyor 31 advanced through a pair of solder applying stations 33 and 34 whereat solder is laid and melted at the junctures of the terminals and contact pads. As a fixture approaches a solder applying station, the conveyor is slowed down and a programmed controller 170 is enabled for operation. If a circuit board is sensed by a photodetector 172, a second photodetector is rendered effective to sense elements 176 projecting from a side of the fixture. The sensed elements 176 effectuate the generation of count pulses and output signals to control the movements of solder applying devices 36 to soldering sites where solder feed devices 136 lay discontinuous stripes of solder at the junctures of the contact pads and terminals.

Abstract: Various permutations of plugs (13) are inserted in keying holes (12) formed in a connector 10 secured to an edge of a printed circuit board (11). A carrier nest (16) is loaded with a permutation array of plugs (13) at a load station (20), advanced to an insert station where the array is checked, and then advanced to an unload station (22) where a group of insert pins act through carrier nest holes (17) to seat the plugs in the connector holes (12). At the inspect station, checks are made for missing plugs and plugs in wrong holes. If plugs in wrong holes are detected, the plugs are dumped from the carrier nest and a new array of plugs are loaded into the carrier nest (16). If a missing plug is detected, the carrier nest is returned to the load station and a plug is loaded into the proper nest hole (17).
