A process for the production of tighthead drums having dimensional stability of the injection molded lids and blow molded drum bodies, comprises blow molding double drum bodies from plastic and centrally separating them into two drum bodies. Tighthead lids are produced by injection molding from plastic. The tighthead lids are then welded to the drum bodies. Widemouth drums are also produced by blow molding double drum bodies from plastic and centrally separating them into two drum bodies, but wi...

Apparatus for transferring visible images from a first surface to a second surface and/or for fusing or fixing a visible image to a substrate, comprising: a cylindrical member secured between two round end plates to form a cylindrical structure; a volatile liquid incorporated within the cylindrical structure in a cavity, at least one wall of which is thermally connected to the cylindrical member; and a heater that heats the liquid to an operating temperature, wherein the amount of the volatile l...

The complete drum comprises two, axially-separable, generally cylindrical sections, which are open, inwardly, toward each other, each of these two sections having but one playing head, so that the two heads are disposed respectively at the outer ends of the cylindrical assembly. When the open ends of these two basic sections are axially spaced-apart to provide an annular gap between them, the space within said sections communicates with the ambient air, through said gap, substantially uniformly ...

A knife scraper for rotating drums, particularly for the drums of a cylinder mill, which exhibits a knife beam (5) in which the knife (3) is mounted as well as a counterweight (12) for pressing the knife (3) on the associated drum (1, 1'). In order to make it especially simple and quick to adjust the knife (5) while simultaneously keeping the installation costs and manufacturing costs low and to make the knife (3) essentially self-adjusting in normal operation according to the invention, several...

A method for forming a plastic drum including the steps of selecting a lower component having a bottom and a generally cylindrical side wall, the side wall defining an opening, and selecting an upper component having a center section and an annular end portion, the end portion having an annular slot. The method further includes the step of locating the upper component on the lower component such that the upper component covers the end opening and such that at least part of the side wall of the l...

A system that reduces worker exposure during coke drum unheading and cutting operations and that reduces risk to workers also provides a capacity increase in that the time a coke drum is not being filled is reduced. This system employs a containment shield that safely permits drainage through the bottom head and contains water and coke avalanches.

Accordingly, a hand truck for musical drums of the invention facilitates storage, transport, protection, and control of drums and drum accessories. The hand truck for musical drums of the invention has a frame and a plurality of drum compartments within the frame. Each compartment has an arcuate inner wall that corresponds to a preselected drum, which is protectively releasably received in the corresponding compartment. A wheel assembly and a handle are connected with the frame and facilitate ca...

A printer including a plurality of print drums and capable of producing, e.g., color printings is disclosed. When a closed position sensor responsive to a door outputs a close signal and when a drum sensor assigned to a print drum to be mounted outputs an absence signal, a controller controls drum drive sections such that a mount/dismount drive section assigned to the print drum to be mounted takes the position corresponding to a mount position. Also, in response to a mount position signal outpu...

An ice scraping system including a scraper blade driven by a pneumatic cylinder coupled to an electropneumatic controller Distance of the blade from the surface being scraped is continuously monitored by a command controller which specifies different electrical command signals for the electropneumatic control device.

A device holder for drums, including a base frame having two eyed lugs bilaterally disposed at one end and a bolt hole spaced between the eyed lugs and a longitudinal open-ended slot at an opposite end, box end bolt inserted through the through hole of the base frame and screwed up with a wing nut to hold a rod member with an instrument in the eyed lugs, an arched retaining block having a fixed end pivoted to the base frame in the middle and a free end, and a locating bolt having a head pivoted ...
