Abstract: A rotary dryer can include a screen that is divided into different portions joined together to form the screen structure. The screen portions can be joined together using one or more quick release latches. Each latch can provide a locking connection between the different screen portions. The latch can be unlocked, e.g., using hand pressure, to disconnect one screen portion from an adjacent screen portion. This can allow quick replacement of one or both screen portions with replacement screen portion(s). The latch may include a latch body and a latch rod. The latch rod may be rotatably connected to the latch body. The latch rod can be connected to one screen portion and the latch body connected to another screen portion. The latch body can rotate around the rotatable connection, causing the screen portions to be pulled together for subsequent use of the screen structure.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for initiating actions based on sequences of events. In one aspect, a process includes receiving, from each of multiple devices, data specifying an event detected by the device.

In response to determining that the events detected by the multiple devices match the first scenario, a first action specified by the first scenario is initiated. A determination is made that a combination of one or more of the events detected by the multiple devices and the first action matches a second scenario. In response, a second action specified by the second scenario is initiated.

Abstract: A multiphase vortex flowmeter system determines the gas-to-liquid ratio (GLR) and flow rates from a well producing multiphase gas, oil and water by detecting the frequency and amplitude of vortices shed in a vortex flowmeter. In particular, the phase of the flow can be identified by detecting the change in the frequency of the vortices with respect to time, and the amplitude of the vortices. Based on the phase, the flow rates of liquid and gas can be calculated. As a feedback technique, these calculated values can be “tuned” by comparison with actual GLR and flow rates recorded for the well by a test separator.
