Abstract: An exemplary vibration isolation assembly for use with elevators includes a first rigid member having an outer wall at least partially surrounding a central opening. A second rigid member is at least partially received within the central opening of the first rigid member. A resilient layer between the first and second members substantially isolates the first member from vibrations of the second member.

Abstract: A pulley assembly for removably fastening an arm cord to an exercise apparatus is disclosed. The pulley assembly includes a yoke having a central portion and a pair of parallel leg portions, the central portion having a bore therethrough, a pulley wheel rotatably supported between the yoke leg portions by an axle, and an elongated stem having an axially extending shaft portion protruding through the bore. The shaft portion has distal end portion having an L shaped slot formed therethrough. The L shaped slot forms a hook shaped end to the shaft portion. A tapered coil spring over the shaft portion of the stem, has a small end and a large diameter around the shaft portion of the stem. The spring biases the hooked end away from an eyebolt on the exercise apparatus to keep the pulley assembly engaged with the eye bolt and hence fastened to the exercise apparatus.

Abstract: An apparatus for treating a fire in a multi-floored building, a method of treating fire in a multi-floored building, and a portable apparatus for assembly and subsequent treating of a fire in a multi-floored building are disclosed. The apparatus, method and system include a curvilinear tubular structure and a bracing system coupled to a source of a fluid pressure.

Abstract: A strap tension retaining device is configured for a use with a bulk unit secured by a strap under tension. Such a bulk unit load has a corner and defines a bulk unit perimeter. The strap tension retaining device includes a fixed base element, fixed relative to the bulk unit load, a floating element movable relative to the fixed base element, a biasing element mounted between the floating element and the fixed base element and a guide element mounting the floating element to the fixed base element to guide movement of the floating element relative to the fixed base element. The strap tension retaining device is positioned at about the corner of the bulk unit load with the strap positioned around the bulk unit perimeter of the bulk unit load, over the strap tension retaining device floating element. When the strap is tensioned a force is exerted by the strap on the floating element to force the biasing element against the bias direction.

Abstract: A wood planing machine includes a machine base having left and right mounting short sides, and feed-in and take-out long sides. Left and right pairs of posts are fixed on a top surface of the machine base at the left and right mounting short sides, respectively. A cutter carriage is disposed above the machine base, and has opposite end portions mounted respectively, vertically and movably on the posts. Left and right threaded rods are mounted respectively and rotatably on the mounting short sides of the machine base such that the threaded rods are disposed respectively between the left and right pairs of posts, and extend threadedly through opposite end portions of the cutter carriage for moving the cutter carriage along the posts. Two sprockets are sleeved respectively and fixedly on the left and right threaded rods. A chain has a front chain section and a rear chain section, and engages the sprockets so as to rotate the left and right threaded rods synchronously with each other.

Abstract: A cable guide for a winch having a lifting drum over which a cable is wound back and forth between two end flanges. A guide body in the form of a truncated cone is slidably mounted upon a pinion that is located adjacent to one end of the drum, generally perpendicular to the axis of the drum. The guide body contains a groove at its narrow end in which the cable rides as it approaches the end of the drum. The guide smoothly plays the cable onto the drum so that it can reverse its direction without producing multiple wraps at the end of the drum. A spring biases the guide body into a home position to accommodate the cable during the time the first wrap is being wound on the drum. Thereafter, the guide automatically moves back against the spring force to automatically align itself with regard to further wrapped layers.

Abstract: A mining machine is controlled by a fiber optic controlled remote control system that includes one or more fiber optic cables that extend from a remote control station through a hose supplying water to the mining machine. The fiber optic cables exit the water hose for connection to electrically operated equipment onboard the mining machine. Connectors having sealing glands with apertures therethrough allow for insertion of the cables into the water hose and exiting of the cables from the hose at the mining machine while preventing the escape of water from the hose at the points of insertion and exiting. The fiber optic cable is supported and positioned for movement in the hose to relieve tension on the cable when the hose is stretched.

Abstract: In a scanning densitometer the mobile head is connected by means of an optical fiber cable with stationary parts of the apparatus. The optical fiber cable is looped around a cable drum and guided by it. The cable drum is suspended by means of two supporting cord layouts looped around it in opposing directions in a rotating manner parallel to the linear path of motion of the measuring head. The supporting cord layouts are mounted stationarily on the apparatus and one of them contains an equalizing spring. This type of a cable conduit is highly protective and therefore particularly suitable for mechanically sensitive parts, such as for example, optical fiber cables.

Abstract: A traction sheave in particular for a lift moving machinery, by which the torque is transmitted from the machinery shaft to the ropes supporting the lift cage. The problem in lift traction sheaves of prior art with rigid construction is their objectionably strong tangential vibration, due to the machinery. In the invention this problem has been solved in that the outer rim of the traction sheave is connected to a flange on a hub by the aid of at least one elastic element, and that the outer rim is rotatably carried on the hub.

Abstract: An implement side shift assembly is disclosed for laterally shifting an earth-working implement relative to a tractor or the like. The side shift assembly includes a frame assembly having laterally extending upper and lower slide rails. An implement support bracket mounts the implement to the slide rails for lateral movement. A slide plate is slidably mounted between the slide rails for lateral movement, and a piston-cylinder is connected between the frame assembly and slide plate to move the slide plate laterally. A latching mechanism mounted on the implement support bracket selectively connects the slide plate to the implement support bracket at one of a plurality of connecting points on the slide plate. One of the features of the invention resides in attaching lift cylinders to the side shift frame assembly at positions as far outboard as possible on the opposite ends of the frame assembly to reduce the bending and twisting moments on the frame induced by the implement.

Abstract: In a machine having a boom, a sheave swivably mounted on the boom and a line reeved over and around the sheave, an assembly for returning the sheave to a predetermined position relative to the boom upon the sheave being rotatably displaced about its swivel axis by forces applied by the line, consisting of a righting arm operatively connected to the sheave for rotatable movement therewith about the swivel axis and means operatively engageable with the righting arm for rotatably biasing the righting arm and correspondingly the sheave about the swivel axis toward the predetermined position.

Abstract: Tensioning device for tensioning of hydraulic flexible tubes on telescopic lift mast assemblies of fork lift trucks with the flexible tubes being turned-around over a pulley which is rotatably mounted on the stationary outer upright and an additional pulley which is rotatably mounted on the sliding inner upright. A holder is engaged by a spring, the holder being guided on the stationary outer upright in a guide, the holder carrying a rotatable pulley.
