Title: Soldering method and apparatus
Inventor: DINES DAVID R
IPC: B23K3/00
Filed: 1988-06-30
Granted: 1990-12-27
Abstract: SOLDERING METHOD AND APPARATUS     Abstract The present invention is directed to a method for soldering each of a plurality of members (40), arranged in one or more parallel rows, to a separate one of a plurality of metallized pads (42) on a substrate (10), each pad being contiguous with a corresponding member. The method is initiated by tilting the substrate so that one end of each row of members and the metallized pads contiguous therewith are at a higher elevation than the other end. A stream (80) of molten solder and a dripping stream (88) of flux droplets are directed onto the substrate into the regions where the members are contiguous with the metallized pads. Simultaneously, the substrate is displaced relative to the streams along a path (96) inclined with respect to the horizontal and parallel to the rows of members so that the members and the metallized pads are successively coated with solder and then flux. The inclination of the substrate is such that the solder and flux flow downwardly, under gravity, past a successive one of the members and metallized pads. The force of gravity on the solder, together with the presence of the flux, is sufficient to break the surface tension of the solder between adjacent members to prevent a solder bridge therebetween.

Abstract: CAM CONTROLLED LABELLING MACHINE FEATURING SETS OF FOLLOWERS RUNNING IN AXIALLY-SPACED PARALLEL PLANES                 ABSTRACT OF THE DISCLOSURE A labelling machine for bottles or the like includes several stations located behind one another along a track.  The stations include an adhesive application station, a label feed station and a label transfer station.  There are three extracting elements which are each mounted to rotate on a rotating support to be moved past the stations during each rotation of the support.  Each extracting element has an outwardly-curved receptacle surface for the label which rolls along the stations.  The drive for each extracting element is a cam drive, which comprises common, stationary double cam discs for all the extracting elements with two cams located on one side in two planes with one above and at some distance from the other.  Two sets of followers are mounted on a bearing shaft which is coupled with the rotating support.  By means of a form-fit with the two cams, the followers provide positive movement of each extracting element over its entire revolution when the support rotates.  The bearing shaft terminates above the plane in which the first cam closer to the shaft is located.  The followers which correspond to the other second cam are mounted on a bridge element lying between the two cams.  The bridge element is supported by spacer elements on the bearing shaft so that the spacer elements lie outside the area or path covered by the movement of the first cam.

Abstract: Abstract A keeper is disclosed for releasable attachment to a chain in order to support a gathered length of the chain at a safe, yet accessible overhead location above the ground surface. The keeper includes a tubular body which can be used to accumulate a length of chain. A finger at an upward, open end of the body may be releasably hooked between openings of adjacent links of the chain in order to suspend the keeper and the accumulated chain length at the selected elevation. The finger is preferably resilient or, alternatively, pivotal to facilitate disengagement of the keeper from the chain by simply pulling downwardly on the keeper handle. The keeper may be completely removed from the chain by pulling forcibly downward on the keeper to disengage the finger from the chain and allow the keeper and chain to move downwardly to the point where the keeper becomes completely disengaged from the chain.
