A device to be inserted into a cardboard tube used for rolled paper goods, the device providing a largely cylindrical interior surface for rolling on a spindle. The device comprising a first member and a second member. The second member comprises a second member body portion threads and the first member comprises a first member body portion threads, which are structured so that the first member body portion threads can be mated with the second member body portion threads, so that the first member body portion is secured inside a portion of the second member body portion. When the first member and the second member are secured together, they form a roller. The roller is inserted into a cardboard tube used to hold paper products to maintain the round structure of the cardboard tube via a first member first end flange and a second member first end flange.

A roller arrangement with at least two rollers arranged axially parallel, wherein a respective nip is formed between adjacent rollers, each of the rollers having a roller journal at both of its two axial ends, each roller being pivot-mounted via its two roller journals, at least two bearings being arranged axially adjacent to one another at least on both of a first roller journal of a first of the rollers and an adjacent first roller journal of a second of the rollers, wherein a compressive stress is generated between an inner bearing on the first roller journal of the first roller and an outer bearing on the first roller journal of the second roller and a tensile stress is generated between an outer bearing on the first roller journal of the first roller and an inner bearing on the first roller journal of the second roller or vice versa.

This disclosure is to provide a laminate with improved adhesiveness between the layers, and a conductive roller having the laminate. The laminate of this disclosure is a laminate comprising at least 2 or more energy ray curable resin layers formed by curing a resin composition with an energy ray, wherein: the laminate has an energy ray curable resin layer (1) and an energy ray curable resin layer (2); and a first resin composition used in formation of the energy ray curable resin layer (1) contains an energy ray curable resin (A) having a hydrocarbon ring skeleton.

A roll stand (1) includes a roll (3), in particular a backup roll, mounted via oil film bearings (2). Each oil film bearing (2) has a sealing system for sealing the oil film bearing (2) to prevent oil leakage and a coolant ingress. The oil film bearing (2) is integrated into an oil-circulating lubrication system (4), which is fluidically connected to the oil film bearing (2) via oil feed lines (5) and an oil discharge line (6). A first sensor (11) is arranged in the oil feed line (5) and a second sensor (12) is arranged in the oil discharge line (6). The two sensors (11, 12) are designed to determine the coolant content in the relevant oil volume flow.

A rotary milking platform (1) comprises a platform (3) having a circular carrier beam (7) secured to the underside of the platform (3). The carrier beam (7) is supported on a plurality of support elements (10), each of which comprise a freely rotatable roller (35) which is configured to rollably engage an under surface (38) of the carrier beam (7). Each support element (10) comprises an anchor plate (27) adjustably mounted on a corresponding ground engaging element (20) which is secured to the ground. A carrier plate (40) is carried on four guide bolts (50) extending upwardly from the anchor plate (27). Side members (41) extending downwardly from the carrier plate (40) rotatably carry the roller (35). Compression springs (59) acting between abutment washers (55) secured to the guide bolts (50) and the carrier plate (40) urge the carrier plate (40) against heads (53) of the guide bolts (50). The compression springs (59) accommodate downward and upward movement of the roller (35) in order to accommodate rising and falling of the under surface (38) of the beam (7). The compression springs (59) permit tilting movement of the roller (35) about a tilt axis (61) which extends in the direction of motion of the beam (7) in order to facilitate tilting of the roller (35) to follow any non-horizontality of the under surface (38) of the beam (7). The tilt axis is located just below a line of contact (67) of the roller (35) with the under surface (38) of the beam (7) to minimise lateral movement of the roller relative to the beam (7) as the roller (35) tilts about the tilt axis.

An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.

A method and an equipment permitting to optimally handle and support a roll made of at least an inert material and transfer the torque from a bearing to a roll or the other way around without damaging them, the roll and bearing being immersed in molten metal.

A roll for an agricultural baler includes an interior tube and an exterior tube surrounding and connected to the interior tube. The exterior tube has an exterior surface and a plurality of loops extending from the exterior surface of the exterior tube.
