  • Patent number: 5005457
    Abstract: A method and apparatus for collection of fecal matter designed to operate efficiently in a zero gravity environment. The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undesirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect fecal matter, scrub the waste collector area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, which valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pad to a face of the piston with each actuation.

  • Patent number: 4367666
    Abstract: A stock feed and shear system which may be utilized in an automatic ticket vending machine for cutting tickets from different rolls of stock and delivering the tickets to other components such as a printer and a magnetic encoding transport. The rolls are supported on reels having releasable clamp mechanisms for allowing rapid replacement of spent reels while providing a predetermined drag between the roll cores and the reels. The reels are spring loaded so that stock can be unwound from the rolls only by positively driving the same with selectively driven pinch rollers. Guide tracks direct the stock to a rotary shear which cuts single ticket lengths from the stock without metal to metal contact, thereby achieving excellent service life. Sensors provide an indication of spent rolls, completion of a cutting operation, and presence of a ticket in the shear. In another embodiment paper or plastic tickets are pre-cut by a two-way rotary shear and are held in escrow.

    Abstract: A device for controlling the feed mechanism for copying material is connected to a coupling at the feed mechanism of the copying material in order to ensure that the respective leading edges of an original and the copying material are fed to a copying zone in congruence irrespective of the throughput speed. For easy adjustment this device is built up with a pulse generator in synchronism with the movement of the original feed mechanism and with a pulse counter the output of which is connected to the coupling. The counter counts the number of pulses in a predetermined period of time and stores this number. Further, the counter counts a second number of pulses occurring after the predetermined period and produces an output signal when the second number of pulses is equal to a predetermined number of pulses less the stored count.
