Abstract: A cottoner having a wadding section forming station, the station having: a carrier, a holder, and a feed mechanism mounted on a base in series. Moving means on the base reciprocate the a carrier toward and away from the feed mechanism. An operating controller on the base open and close the holder. The carrier has a gripper for gripping a length of wadding material to carry it from the holding means toward the feeding means when the carrier is moved toward the feed mechanism while the holder is open. The carrier releases the length of wadding material when moved away from the feed mechanism while the holder is closed to hold the length of wadding material. The cottoner includes an inserting station for inserting each section of wadding material formed at the wadding section forming station into a container. The cottoner also has a sensing station for sensing if the wadding material has been inserted, and inserted properly, into the container at the inserting station.

Abstract: A tape feeder for advancing a carrier tape with pockets containing parts in a surface mount placement system enhances the precision and reliability with which the tape is advanced and reduces the risk of loss of parts in uncovered pockets due to vibration by provision of a sprocket wheel to advance the tape, a reciprocating shutter to retain parts in uncovered pockets, and a retaining member disposed above an edge of the tape for contacting a portion of a top surface of the tape to retain the top surface portion in a plane when the tape is engaged by the sprocket wheel. The operation of the retaining member is assisted by a guide member including front and rear guides that contact the top surface of the tape and a support block that is pressed by a support spring against the bottom surface of a portion of tape between the front and rear guides. The operation of the tape feeder is adjusted to accommodate different pitches.

The pitch adjusting device adjusts the tape feed pitch in accordance with the dimensions of chips to be fed. Chips which are transported to the chip takeout section are removed from the tape by means of suction after a protective cover covering the tape has been separated therefrom.

Abstract: A single mechanism performs three or four functions in a camera, the advancement of a film (6) mounted therein being used to provide energy to the mechanism. A tracking pin (2) is guided in a track (3) causing a tracking member (1) to move in a cyclic manner. For part of the cycle, a clawed end (4) of the tracking member (1) is in engagement with the film (6), the advancement of which causes movement of the tracking pin (2) along the forward portion (3a) of the track (3), and extension of a first tension spring (12). On movement of a shutter release lever (11) the tracking pin (2) moves rapidly along the remaining rear portion (3b) of the track (3) under the action of the tension springs (12, 13). A frame counter mechanism (7, 8, 9, 10) is actuated by the tracking member (1) at a convenient point. The shutter mechanism is also activated at a suitable point after operation of the shutter release lever (11).

Abstract: An advance mechanism for perforated materials for advancing the material through a path of light. The mechanism includes a support structure adapted to be in line with a source of light so that light passes through an aperture in the support. The perforated material is supported and advanced along a pathway into and out of alignment with the aperture. A pawl mechanism including a spring is on the support adjacent to the aperture and normally positioned in a normally retracted position in alignment with a slot adjacent to the aperture in the support. Drive structure biases the spring and directs the pawl through the slot into engagement with a perforation in the material and then along the slot a predetermined distance to advance the material and then release the pawl permitting the spring to return the pawl to the retracted position out of the slot. The pawl is then returned to the normally retracted position. The movement of the pawl along the length of the slot is restricted.

The control drum is provided on its periphery with a plurality of different cam curves and a pin, movable in a direction normal to the axis of the control drum, engages with one a cam curve, brought in a selected position of the drum in alignment therewith, while the other end of the pin cooperates with a pull-down pawl to move an end of the latter into and out of perforations of the film. The worm gear meshes with a worm driven by a shaft carrying a cam engaged by a cam follower connected to the pull-down pawl to move the latter along a feed stroke when the end of the pull-down pawl is engaged in one of the film perforations.

Abstract: The invention is concerned with a motion picture projector or camera, with a claw for feeding the motion picture film, having at least one switch provided in one or several electric circuits of the motion picture projector or camera, which switch is controlled by said claw. An 8-mm motion picture camera in which a switch for various circuits of the camera is provided within the intercept of the claw is already familiar. In such an arrangement, contact elements of the switch are kept mutually in mesh by the claw while it engages the film or disengages from its perforations and if there is no film, the claw releases or opens these contact elements. Switching contacts of this type may be provided, e.g., in the electric circuits of the feed mechanisms or of the exposure control device of a motion picture camera. In this way, when no film is inserted, the batteries are unable to discharge.

Abstract: In the present cam-driven intermittent movement for motion picture machines the pull-down action is shared by a plurality of cams mounted on a common shaft and operating in tandem, thereby reducing the noise and vibration and/or permitting faster pulldown. One cam drives a claw arm in its swinging movement about a pivot, while the other cam drives a carrier arm which is pivoted at one end on the machine frame and carries at its other end the claw arm pivot. Meshing action of the claw may be controlled by cam action applied to either arm. Such action may be derived from the same cam as the pull-down action, or may employ an auxiliary meshing cam.
