Title: Tank Units for Fuel Tanks
IPC: B60K15/06
Filed: 1980-09-09
Abstract: A tank unit comprises a top plate 2 which is formed as a one-piece moulding and incorporates at least one spigot 26, 27 for receiving a pipe connector 3 for a feed or return fuel line, said spigot defining a bore 28, 29 passing through the top plate and being surrounded by a concentric cylindrical sleeve 31. The inner surface of the sleeve, and the outer surface of the plug part 33 of the connector, each provides a section 32, 34 provided with serrations. The arrangement is such that the plug part of the connector can be fixed to a spigot, and sealed via a sealing ring, by push fitting said plug part into the spigot and into engagement with the inner surface of said sleeve, the two sections of serrations being of a form such that they interact to prevent withdrawal of the plug part once assembled. <IMAGE>

Title: Automatic jumble-filling machine
IPC: B65B19/34
Filed: 1980-09-27
Abstract: Elongate articles, e.g. wrapped chocolate bars, are jumble-filled into an open-topped carton by diverting successive counted-off even fractions, e.g. quarters of the number of articles to be packaged in a carton, the articles falling into alternate ones of two chambers which are so sized and shaped that the articles are automatically grouped into parallel but non-coaxial alignment; dropping the groups of articles alternately from said chambers into respective further chambers in each of which the articles form a stack; and, when two such stacks have been formed adjacent one another so that each forms a mirror image of the other in a vertical plane halfway along a carton positioned therebelow, releasing both stacks at substantially the same moment. The articles then spread evenly over the carton floor without skewing, and the process is repeated until the desired number has been cartoned. As shown an oscillating paddle comprising a central divide (24) and two drop plates (25, 26) may be provided to define the first two chambers with side walls (29 and 31). Carton erecting apparatus may be associated with the machine and the carton may start in a raised position and be lowered during filling. <IMAGE>

Title: A closed die forging method and apparatus for making a flanged part
Inventor: DIEMER DONALD JOSEPH
IPC: B21K1/02
Filed: 1982-10-12
Abstract: A method of forging track tractor rollers and other multi-flanged rollers, which comprises busting of a billet to a preformed coned end and placing a split ring (22) around the coned end of the busted and preformed billet, and inserting the same in a stepped blocking die (27) to form flanges by blocking against the split ring and the stepped die for one flange and between the top die on the other flange and removing the split ring and billet. By arranging for one flange to be defined by steps (28) in the bottom die cavity, rather than by the split ring, greatly improved dimensional accuracy of the flange is achieved. When placed in a finishing die, the hollow of the roller is formed by a displacement method which forces the metal into the flanges against the split ring. <IMAGE>
