Abstract: ABSTRACT OF THE DISCLOSURE     A floating and trolling bait bucket for holding live bait.  The floating and trolling bait bucket includes a container, door, hinge, and spring.  The hinge rotatably interconnects the door to the container.   The spring is positioned  over  the  hinge  so  that  the  spring  resists rotation of the door away from substantially closed or open positions.   In addition, a process is described for blow molding a floating and trolling bait bucket having both a container and a flotation collar.  An elongate tube of molten plastic called the parison is extruded between two mold halves, where each of the mold halves includes a cavity having two independent segments and an interspace therebetween.   The mold halves are closed together, and air is then blown into the hollow of the parison, forming the container and flotation collar of the floating and trolling  bait  bucket.   Moreover,  flash  forms  in  the interspace  to  bind  the  container  and  flotation collar together.

Abstract: Abstract of the Disclosure An arrangement on a water craft for collecting oil that is present on the surface of the water, particularly among ice blocks.  The underside of the craft's bow has been made substan-tially planar and very gently inclined, for instance about 10-20°, so that, when the craft is travelling forward the ice blocks, may be forced along the underside under the water and be simultaneously flushed in the water.  Moreover, in said underside water inlet openings have been provided which are elongated, parallel slits and which prevent the entry of ice blocks.  Inside the craft, the oil is separated from the water by means of a separating member, whereafter the water is pumped out again.  To intensify the flush-ing of the ice blocks, the pumped-out water is jetted against the ice blocks in the region of the inlet openings.  The bottom of the bow may be slightly deeper at its sides than at its planar centre-part.

Abstract: ABSTRACT OF THE DISCLOSURE         Process for preparing perfluorobutadiene and higher perfluoroalkadienes, with terminal double bonds, said process being characterized in that .alpha., .omega.-diiodoperfluoroalkanes are deiodofluorinated by means of an organometallic compound in the presence either of an aprotic solvent belonging to the class of hydrocarbons, or of an aprotic polar solvent.  The process is suitable to be realized on an industrial scale with short reac-tion times, with economical and not polluting reacting materials. Perfluoroalkadienes are useful in many fields for example as termonomer, in small amount in the presence of vinylidene fluor-ide and hexafluoropene to produce fluoroelastomers curable with peroxides; as termonomer in the presence of C2F4 and trifluoroni-trosomethane to manufacture another curable fluorinated elasto-mer.
