Abstract: A pair of thermoplastic workpieces are spin welded by placing one element in a non-rotatable, reciprocable clamp. Another workpiece is press-fit onto the first workpiece and the clamp is shifted toward a continuously rotatable collet having radially inwardly closable jaws. A mandrel extends from the collet and projects beyond the jaws to guide the workpieces between the jaws. The mandrel is axially inwardly displaceable by the workpieces, with inward movement thereof being yieldably resisted by a spring to insure that radial shoulders on the workpieces are in abutment. When the other workpiece is positioned between the jaws, the jaws are closed radially into driving contact with such workpiece to substantially instantly rotate the latter at the speed of the collet relative to the one workpiece. Frictional heat thus generated melts the interface between the workpieces. When the other workpiece is released from the jaws, it adheres to the one workpiece.

Abstract: As a scanning element of an electrophotographic copying machine begins to move, a feed roller moves a sheet of copy paper into the bite of register rollers which are held stationary. This movement of the copy paper is accomplished in a period of time which is less than that required for the scanning element to reach a predetermined scan synchronizing point. The feed roller is then stopped so that the copy paper is slightly buckled and thereby resiliently urged into the bite of the register rollers. When the scanning element reaches the scan synchronizing point, a sensor causes the register rollers to rotate thereby feeding the copy sheet through the machine in synchronization with the movement of the scanning element. The copy machine may employ a seamless photoconductive drum or belt moving at constant speed in which case an electrostatic image is formed on the drum or belt by the scanning element. The image is developed by toner particles and transferred to the copy sheet.

Abstract: A taping machine for applying a protective wrapping to small parts, particularly electronic parts such as capacitors, having a longitudinal axis.

Abstract: The following specification describes apparatus for successively applying magnetic patches on a tape to successive passbooks. Each passbook is moved in sequence to engage a switch and is then stopped. The switch operates a solenoid, which engages a roller with the passbook and disengages the stop. Thereafter, a metered pulse is applied to the motor of a rotary drive to move the passbook and tape through the same distance and one patch is separated from the tape and applied to the passbook by the solenoid engaged roller. As the tape moves under control of the metered pulse, a succeeding patch on the tape is sensed by a photocell to maintain the motor and rotary drive operated. The drive continues to advance the tape and when the succeeding patch is no longer sensed by the photocell, it provides a signal to deenergize the motor and stop the tape. The succeeding patch is thus accurately positioned for application to the next passbook operating the switch.
