Abstract: To simplify the insertion and to improve the stability as well as to avoid mechanical damage to a ceiling of an industrial furnace, the invention proposes a fire-resistant ceiling element to be used as a self-supporting building element which can be inserted on the side of the furnace channel.

Abstract: The inlet nozzle suitable for swimming pools is constructed as a two-piece-spherical body. This is pivotally graduated on a seating ring and equipped with a continuous bore. One part of the spherical body is, with respect to the other, rotatable about the one axis which runs eccentrically with respect to the axis of the bore. Thereby the cross-section of the bore can be changed at the transition point between both bore sections by turning of the one part of the spherical body. Between the two parts is a gap through which air from the air pipe is introduced.

Abstract: In order to adjust desired web lengths between perforations, a perforating cutter (6) is used which consists of two mutually rotatable cutter discs (10 and 11) which can be fixed in the adjusted positions relative to each other. One cutter disc (11) has thereby a flat radial cutting surface (12) which constitutes the base of a flat truncated cone, the lateral face (16) of which corresponds to the inner lateral face (15) of a pot-shaped cutter disc (10), of which the outer lateral face (14) forms, together with the cutting face (12), a cutting edge (19) at which also terminate the lateral face (16) of one cutter disc (11) and the inner lateral face (15) of the other cutter disc (10). Provided in the cutting edge (15) and around the periphery are regularly equidistant cut-outs (24), of which the length and thus the length of the webs between the perforations can be adjusted by rotation of the cutter discs (10 and 11 ) in relation to each other.

Abstract: A free drop container for liquids and especially potable liquids such as water. The container includes a molded impact resistant shell having a generally spherical shape. A port in the shell defines a hole through the shell wall, with the hole having a first diameter extending from the exterior partially through the shell wall and a second smaller diameter extending through the rest of the shell wall to the interior thereof such that the two diameters define a seat in the shell wall. A screw-in cap is removably fitted to close the first diameter hole preferably by cooperative threading with the circumferential surface of the first diameter hole. A pour spout is sized to slidably fit the second diameter hole, and can extend out from the shell for pouring when the cap is removed. A plug is removably fitted in the pour spout, and a resilient impact-resistant lining is provided that does not crack or break on impact and covers the interior of the shell for contact with potable liquids inside the shell.

Abstract: A fiber optic cable innerduct for containing and protecting fiber optic cable and for reducing the friction drag on the fiber optic cable as it is being pulled through the innerduct to allow for longer and more efficient cable pulls comprises an innerduct having a base with a circular cross section and longitudinal ribs spaced around the inner surface of the innerduct supporting the cable and for reducing friction drag on the fiber optic cable when it is being pulled through the innerduct by riding the fiber optic cable on the top ridges of the ribs.

Abstract: A barrel for holding, handling, or storing large quantities of bulk material such as meat and other food products features a seamless, one-piece plastic construction with integrally formed recessed handles for lifting or moving the barrel and integrally formed gussets to strengthen the barrel, and with nesting stop surfaces for nesting empty barrels, and with stacking surfaces and a lid for stacking filled barrels.

Abstract: A guide block (11) has a groove (16) with a flat floor cut into it, in which an endless belt (15) containing perforations (17) travels. A suction opening (18) opens into the floor of the groove (16), to which a vacuum is periodically applied by means of a valve (12). The endless belt (15) travels over a stack (1) of sheets (2) by means of guide rollers (4,5) and a drive roller (3). The vacuum, when periodically applied by the valve (12), operates through the perforations (17) so that the topmost sheet (2) of the stack (1) is sucked against the endless belt (15) and carried away in the same direction (28). One preferred form of the endless belt (15) is a toothed belt, with spaces between the teeth (21) that form vacuum chambers (22). With this compact and therefore easily positionable device, sheets (2) are sucked up from a stack (1) and transported away while maintaining their orientation, meaning that very high production rates are attained.
