An industrial drum constructed of synthetic resin material by rotational molding, the material being a crosslinkable high density polyethylene resin having the ability to crosslink as the drum is molded. The top end wall of the drum carries a bung opening, and an integrally molded chime at the intersection of the top wall and the side wall has a configuration which enables gripping by a mechanized drum-handling apparatus and which includes a drain trough spaced at least a minimal distancefrom th...

A drum is built on a rigid cylindrical frame primarily composed of two circular end supports in the form of rings, a cylindrical body shell between them, and a set of parallel spaced elongated brackets interconnecting these.

A cable drum of the type which is penetrated from end to end by a central hole is provided with means for supporting the drum in an up-ended position on a cushion of pressurised fluid, (e.g. water). The said means comprise a flexible skirt of annular form disposed around the periphery of what, in use, is the lower end of the drum so as to define a cushion space, and water pump means whereby pressurised water can be supplied to said cushion space by way of the said central hole so as to support s...

A cable drum comprising a carrier, a drum body for taking an extension cable and having a cylindrical part with first and second axially spaced end walls, and a plug base having at least one socket connected electrically with an extension cable, the drum body incorporating a holder for a lamp and a switch enabling electrical connection to be established between the lamp and the extension cable.

A musical drum has a hollow elongate body of resin impregnated glass fibre, open at both ends. A membrane is stretched across one end and secured thereto. The said end is circular and the body has a cylindrical portion including the said end and then has a flared portion with a curved central axis. The flared portion terminates in a generally oval opening and includes a hollow ridge. In use of the drum, two notes are produced, one at the center of the open end and the other, an octave lower, in ...

The invention relates to a drum shell for a musical drum, the drum shell comprising at least one portion molded or cast as one piece in natural or synthetic material, so enabling internal and external surfaces of the drum shell to be made in any desired shape.

A palletized drum assembly in which drums are stacked in successive layers, each comprising plural drums, on a transportable pallet, with anti-roll spacers between the layers, and the stack is releasably secured to the pallet by strap passed about the former and fastened to the latter. The assembly is dismantled for individual filling of the drums when empty by transferring the stack to a pivoted receiver in the vertical condition, rotating the receiver to a stack-supporting intermediate angular...

A folding drum of a folding device is comprised of at least one folding element and a transmission unit. The transmission unit has at least one toothed wheel which is coaxially arranged with respect to the rotational axis of the folding drum. The toothed wheel can be moved in the axial direction of the folding drum between at least two positions.

An apparatus for use as an intermediate transfer member or fusing member in an image forming device includes a cylindrical member having a thickness that is insufficient to support it in use and which is secured between two round end plates to form a cylindrical structure which is unsupported between the endplates. A liquid is incorporated within the cylindrical structure and a heater is also located within the cylindrical structure so as to heat the liquid to produce a vapor wherein the vapor i...

A drum washer has a base, a barrel support structure, and a water delivery system. A hollow drum is turned over and placed on the drum washer by inserting a spray head of the water delivery system through a hole in a top cover of the drum and into the interior of the drum. The barrel support structure holds the drum at a fixed angle while water is sprayed from the spray head onto interior surfaces of the drum. The water rinses the interior surfaces of the drum and drains out the hole in the top ...
