Title: Method for testing snubbers in situ and a snubber system for use in the method.
IPC: G01M99/00
Filed: 1980-10-14
Abstract: The invention relates to the testing of seismic shock absorbing snubbers (20) in situ.

Title: Underwater pipe laying vessel
IPC: B63B35/04
Filed: 1982-03-29
Abstract: An underwater pipe laying vessel for laying a continuous pipeline, applying what is known as the "J" shape pipe laying method, uses shorter lengths of pipeline welded together on board end to end to form pipe assemblies the pipe assemblies are stored and subsequently transported to a pipe laying boom unit which guides pipe assemblies to be welded end to end to a pipeline which is already in the "process of laying" under the vessel. The pipe laying boom is located substantially in the center of the vessel and is swivelled about a horizontal axis which is perpendicular to the length of the vessel the boom includes a flash butt welder and an underlying jacketing-unit for suitably treating a welded surface of the pipeline to prevent subsequent corrosion a pipeline section guide and pipeline section support located under the jacketing-unit assist in supporting and guiding the treated pipeline for proper positioning. Shorter lengths of pipe and the pipe assemblies are stored, handled and moved on board the vessel expediently on conveyors and rollers in such manner that the length of each pipe and pipe assembly is always parallel to the longer axis of the vessel. The invention provides very efficient and speedy pipe laying operation which is monitored from a control station on board the vessel.

Title: Method for the manufacture of an egg carton.
IPC: B31B50/64
Filed: 1985-05-24
Abstract: In an egg box made from slitted cardboard blanks of which one provides wave strips joined only at their wave crests for folding around to make pockets for the eggs and the other blank provides flat bottom and side panel or cover strips which brace the wave strips by being glued to the wave trough bottoms of the wave strips, top cover strips respectively glued to the half width wave strips that come together (when the top wave strips are folded around the eggs already packed in the pockets previously formed,) do not both correspond in width to the top wave strips, but one of them has an overlapping free edge the underside of which is bonded adhesively to the other top panel strip. The adhesive bonding is done with a hot-sticking adhesive which when cooled without being covered is no longer sticky. The adhesive is laid down in strips on the wider and shorter blank which provides the cover strips at locations corresponding to the wave trough bottoms that are to be glued on. While it is hot the longer and narrower wave blank, bent into waves, is glued on, leaving the edge portion of the wider blank with spaced cross-ribbons of adhesive which are allowed to cool so that they are no longer sticky. The glued blanks are then filled at a packing station but before they are folded to make pockets, for the eggs, the free edge strip is heated with hot air to soften the adhesive ribbons and then the box is set up and filled and after the top of the box is folded into place, the overlapping free edge strip is pressed against the underlying cover strip to stick the two together. When the adhesive has cooled the pack is secured.
