Abstract: A scaffold mounted hoist (20) is provided which mounts with an adapter (30) on a pin (91) extended upward from the scaffold. An electric motor driven transmission (42) causes a standard (40) to rotate relative to the adapter. A cable from an electric winch (50) on the standard is reeved through a pulley (48) on a boom (44) extending from the standard. The transmission and winch motors respond to receivers (56) in the hoist. Thus a load (28) attached to the cable can be lifted, lowered and swung circumferentially through commands from a hand held transmitter (24). An electric eye system (64) stops the load adjacent the boom. Timers (252, 253) stop the load when it nears, respectively, the ground and the scaffold floor (34).

Abstract: A seat belt retractor is formed of a frame having a pair of side plates which face each other and having a back plate which interconnects the side plates, a reel shaft rotatably mounted between the side plates and having both ends projecting to exterior areas of the side plates, power springs linked in series for energizing the reel shaft in a direction of retracting a seat belt. The power springs have different spring constants. The retractor has a force adjusting device for enlarging force of retracting the seat belt by taking up the power spring having a small spring constant and for weakening the force by releasing the power spring of the small spring.

As the inner elements move inwardly the sliding contact of these tapered surfaces cam the outer elements into gripping contact with the inner surface of the core.

Abstract: The device for feeding reels into a packaging machine comprises a buffer magazine for the reels. The reels are advanced one after the other along the magazine by a conveyor belt provided with pairs of uniformly spaced teeth for supporting individual reels. A distribution element, comprising a supporting element and a resiliently urged tape, guides a first one of the reels into a removal position, and a transfer device transfers the reels sequentially from the removal position, through a reel guiding channel, to an underlying receiving position, at which a device operates for changing the reel to be unrolled in the packaging machine.

Abstract: A method and apparatus for manipulating hot metallic material includes placing a coil of the material at a first position, the coil having an open coil eye, and initiating uncoiling of the coil while it is in the first position. During uncoiling, the coil is transferred to a second position by moving it in a direction transverse to its axis, and heat loss from the coil side edges and eye is restricted by providing a heat shield closely adjacent to the side edges. The uncoiling continues at the second position, and when the coil is near the end of the uncoiling operation at the second position, a coil opener pin is inserted axially into the open coil eye without contacting the coil, thus avoiding conductive heat loss to the pin. Finally, at the completion of the uncoiling operation, the last few coil wraps are pulled into contact with the pin as the coil is pulled downstream out of the second position, whereby the pin prevents collapsing or crushing of the final portion of the coil.

Abstract: A band-changing apparatus for flying band change which consists of two unwinding stations which are arranged adjacent to a band changer. From the respective unwinding stations, a new band and a running-off band are brought together in the band changer in a V-shaped manner from the top downwards through two channels and enter into a pressure-roller unit rotary stops are provided in the channels for controlling movement of the respective bands. The band changer also possesses two rotary crosscutters for cutting the bands to size. The new band is equipped with an adhesive strip which leads to an adhesive bond with the running-off band in the pressure-roller unit.

Abstract: A magnetic tape cassette loading and winding apparatus having a pivotable adhesive tape applicator for splicing the end of a leader tape to the end of a magnetic tape and winding into the cassette. The loading and winding apparatus has three tape holders. Two of the holders are pivotally mounted so they can be moved to sequentially change position to first hold the leader tape while it is cut, hold one cut end of the leader on a free end of the magnetic tape while it is spliced with an adhesive tape, and then hold the other cut end of the leader tape and a second cut end of the magnetic tape while it is spliced. The pivotable tape holders can thus perform several functions. A movable adhesive tape is also provided to move from one position to another to apply pieces of adhesive tape to the cut ends of leader tape.

Abstract: A spindle is mounted to a frame for rotation about the spindle axis. A core yarn package of elastic core yarn is held stationary on the spindle. Elastic core yarn is withdrawn from the core yarn package in a direction substantially along the spindle longitudinal axis. A nonelastic covering yarn is drawn from a supply package, through the spindle and along a confined yarn guide passageway from the spindle guide passageway outwardly, upwardly and inwardly around and in spaced relation to the core yarn package for confining and guiding the covering yarn, and then into wrapping engagement with the withdrawn core yarn to form a corespun yarn.

Abstract: An auto rewinder for a video cassette includes a base, a tape leading mechanism mounted on the base for leading a portion of the tape out of the cassette, a locking mechanism to prevent the actuation of the tape leading mechanism when no tape cassette is loaded in the rewinder, a delay breaker mechanism for delaying the cutting off of the power supply to the motor to permit the tape to be drawn back into the cassette after rewinding has been completed. An ejection mechanism for automatically ejecting the cassette, the ejection mechanism being activated by increased tension in a spindle drive belt when rewinding is completed.

Abstract: An unwinding apparatus supports a reel (60) of web material (22) which is to be unwound and directed into a printing unit (14) having a front/operator side and a rear/gear side. The unwinding apparatus comprises a frame (16) including a rear side part (28) located at the rear side of the printing press (14), and front side parts (24, 26) located at the front side of the printing press (14). The front side parts (24, 26) define an opening in the frame (16). Guide and locating bars (38) on the frame (16) extend from the rear side part (28) to the front side parts (24, 16) of the frame (16). The apparatus further comprises a movable reel cartridge (18) having front and rear cartridge frame parts (64, 66) for supporting the reel (60) of web material (22). The reel cartridge (18) is movable through the opening in the frame (16) and onto the guide and locating bars (38) to locate the reel (60) in its operating position.

Abstract: A tape cassette including a rib projecting upwardly from a bottom wall of a cassette case at a position between the center and one side of a tape drawing recess formed at the front of the cassette case, the rib being disposed close to the back surface of the tape, and a projection that projects from a back lid which, in a closed position, protects the back surface of the tape. When the back lid is rotated to reach an open position, the projection is kept in contact with an upper end of the rib. Accordingly, even when a part of the tape is lifted by the back lid during a lid opening operation, the tape is prevented from entering behind the rib, thereby also preventing tape jamming and damage to the tape player.
