  • Patent number: 11957577
    Abstract: Embodiments of delivery systems, devices and methods for delivering a prosthetic heart valve device to a heart chamber for expanded implementation are disclosed. More specifically, methods, systems and devices are disclosed for delivering a self-expanding prosthetic mitral valve device to the left atrium, with no engagement of the left ventricle, the native mitral valve leaflets or the annular tissue downstream of the upper annular surface during delivery, and in some embodiments with no engagement of the ventricle, mitral valve leaflets and/or annular tissue located downstream of the upper annular surface by the delivered, positioned and expanded prosthetic mitral valve device.

  • Patent number: 4355365
    Abstract: A programmable system for controlling the cyclic intermittent operation of a device, such as a flowing gas well. The system comprises battery powered, solid state circuitry including a programmable memory, an up/down counter and a liquid crystal display for the contents of either the memory or the counter. Programming and control information is introduced into the system through a plurality of touch actuated membrane switches under control of logic circuitry. The memory is first programmed with the desired "on" time and "off" time with which the controlled device is to be cyclicly operated. Once started, the system loads the time for the selected starting condition into the counter, establishes that condition in the device and begins counting down toward zero. When zero is reached, the opposite condition is established in the device, and the time for the duration of that condition is loaded from the memory into the counter which begins the down counting cycle again.

  • Patent number: 4354524
    Abstract: An automatic reset pneumatic timer for control of a motor valve on a lift gas injection system of an oil and gas well or a plunger-pump well installation in an oil or gas well. The pneumatic timer includes means for connecting the timer with a source of air or gas pressure, means for connecting the timer with the operator of a motor valve, a cycle timer including a pneumatic valve, an on timer including a pneumatic valve, a pneumatic relay valve connected between the on timer and the motor valve for directing a pressure signal to the motor valve when the on timer is operating, and a pneumatic automatic reset valve connected with the source and the cycle timer and on timer for resetting both timers to initiate a new sequence of operation when the prior sequence is completed. One form of the pneumatic timer operates solely in response to the cycle timer and on timer of the system.

  • Patent number: 4333527
    Abstract: An improved side pocket mandrel having a body comprising a one-piece main body section in which a main bore and a receptacle bore extend longitudinally therein and an upper body section having space therein for operating a kickover tool, welded together with a circumferential weld. In another embodiment, the machined main body section is welded by circumferential welds between upper and lower body sections. Additional embodiments are further disclosed having means therein for orienting kickover tools which are run and manipulated by wire line or pump down techniques and also having deflectors therein for deflecting regular well tools back into the main passage when approaching the receptacle from above and yet guiding flow control devices into the receptacle when such device is moved laterally into alignment with the receptacle by a kickover tool. Some disclosed embodiments have check valve means controlling flow between the exterior and the interior thereof.
