Patent ES-428330-A1 (ES)
Title: Cartridge tape player system having reverse and fast-forward modes of operation
IPC: G11B23/07
Filed: 1974-07-16
Abstract: A cartridge tape player sytem includes a tape cartridge having the usual continuous loop tape mounted for movement through the cartridge on a rotatable hub. The hub is coupled to a central shaft extending through the outer wall of the cartridge. A circular platen is mounted for independent rotation in the cartridge beneath the hub about the central shaft. The hub and wound tape rests on the platen. The cartridge player of the system includes the usual cartridge receiving cavity, magnetic tape head and capstan drive shaft for engaging a pressure roller in a cartridge received in the cavity and driving the tape through the cartridge in a first direction the tape being removed from the hub at the inner convolution and returned thereto at the outer convolution. A one-way clutch arrangement joins the hub and platen for rotation when the tape is moved in the last-mentioned direction. An auxiliary drive shaft mounted at the entrance of the cavity is coupled to the capstan shaft and is driven rotatably thereby. Reverse and fast-forward pushbutton controls are provided on the player. The reverse button, when depressed, raises the drive shaft for engagement with the central hub shaft of the cartridge to drive the hub in a reverse direction, opposite from that when driven by the capstan shaft. In this case, the tape is removed from the hub at the outer convolution and returned at the inner convolution. To accomplish the latter, guide fingers are provided in the cartridge which separate the inner convolution of the tape from the hub to permit the incoming tape to be "tucked" therebetween. The one-way clutch is disengaged to permit independent rotation of the hub and platen to ensure proper winding of the tape about the hub during the reverse mode of operation. A pivotal member actuated by the depression of the pushbutton moves the cartridge away from the capstan shaft and tape head to permit the raised drive shaft to engage the central hub shaft. An expansion ring in the cartridge surrounding the wound tape contracts upon movement of the cartridge away from the capstan shaft to limit the diameter of the wound tape and to ensure proper reverse winding of the tape about the hub. Depression of the fast-forward button also raises the drive shaft into driving engagement with the central hub shaft and pivots the pivotal member to move the cartridge out of engagement with the tape head and capstan drive shaft. A member coupled to the fast-forward pushbutton likewise operates a switch to reverse the direction of the drive motor driving the capstan and auxiliary drive shafts, thereby to drive the latter in the proper rotational direction. Also, a member is moved toward the cartridge to engage a pin extending from the cartridge. The last-mentioned pin is depressed thereby inwardly of the cartridge to hold the expansion ring in an expanded state away from the wound tape while in the fast-forward mode of operation. The one-way clutch is also engaged to join the platen and hub for rotation.

Patent ES-437131-A1 (ES)
Title: Safety clutch device
IPC: B30B15/12
Filed: 1975-04-29
Abstract: A clutch or coupling device for interconnecting a drive shaft to an axially aligned driven shaft which supports drive sprockets for chain belt conveyor of a press characterized by a disk member connected to the drive shaft for rotation therewith and having a plurality of recesses which have converging planar side walls and are circumferentially spaced on a circle coaxial with the axis of the drive shaft to receive circumferentially spaced dogs which have slanting plane surfaces extending substantially parallel to the side walls of the grooves and are mounted on a flange member which is connected by a mounting device to the driven shaft. The mounting device directly transfers rotational motion between the flange member to the driven shaft but enables relative axial movement of the flange member from a first position with the slanting plane surfaces of the dogs engaged with the side walls of the recesses to transfer torque between the shaft to a second position with the slanting plane surfaces withdrawn from engagement and includes a spring device for biasing the flange member to the first position. In operation, when an overload occurs, the increased torque acting on the engaged slanting surfaces of the dogs and recesses overcomes the force of the spring device and urges the flange member axially to the second position to disengage the coupling between the drive shaft and driven shaft.

Title: Apparatus for forming a fiber strand into cycloidal loops
IPC: B65H54/76
Filed: 1979-11-28
Abstract: A cylindrical tube is inclined from the vertical below a sliver guide, the bottom end of the tube being mounted on a supporting element, and the upper part being accommodated in a bearing, the outer race of which is located in a horizontal plate.
