  • METHODS AND SYSTEMS FOR DRAINING CEREBROSPINAL FLUID INTO THE VENOUS SYSTEM
    Publication number: 20240299714
    Abstract: Methods for treating hydrocephalus using a shunt, the shunt having one or more CSF intake openings in a distal portion, a valve disposed in a proximal portion of the shunt, and a lumen extending between the one or more CSF intake openings and the valve, the method comprises deploying the shunt in a body of a patient so that the distal portion of the shunt is at least partially disposed within a CP angle cistern, a body of the shunt is at least partially disposed within an IPS of the patient, and the proximal portion of the shunt is at least partially disposed within or proximate to a JV of the patient, wherein, after deployment of the shunt, CSF flows from the CP angle cistern to the JV via the shunt lumen at a flow rate in a range of 5 ml per hour to 15 ml per hour.

  • Low headroom coke drum unheading device
    Patent number: 7169266
    Abstract: A coke drum head is hinged to a coke drum body using a compound joint such as a trammel pivot, and the head is moved between open and closed positions using an actuator. In moving between open and closed positions, the head traces out a non-circular path which reduces the required headroom relative to a head using a standard pivot.

  • Automated chute system
    Patent number: 5628603
    Abstract: The inlet of a coke chute is pushed upwards by a plurality of actuators until it encompasses the bottom outlet of a coking vessel. The inlet is preferably surrounded by a skirt which tapers inwardly from top to bottom, and the entire chute is preferably retractable below the level of the floor underneath the coking vessel. A plurality of locks can be used to secure the skirt to the lower portion of the vessel.
