Abstract: A downhole gas ventilation system includes a perforated tubing positioned within a production tubing installed in a wellbore. The perforated tubing couples to wellbore equipment positioned uphole of the perforated tubing within the wellbore to flow multiphase hydrocarbons received within the perforated tubing into the wellbore equipment. The perforated tubing includes two ends and a sidewall connecting the two. Multiple perforations formed in the sidewall receives the multiphase hydrocarbons within the perforated tubing. The perforated tubing outer diameter is smaller than the production tubing inner diameter. The perforated tubing facilitates separation of the liquid phase from the gaseous phase. A one-way check valve is coupled to the upper end of the perforated tubing to vent the gaseous phase that rises towards the upper end out of the perforated tubing, out of the production tubing and into an annulus defined between the production tubing and the wellbore inner wall.

Abstract: An insect dispensing system is described. The insect dispensing system includes a plate diverting structure supported by a frame. A first plate of the structure includes a set of channels and a second plate of the structure includes a set of apertures. The plates are aligned such that one end of each channel is aligned with one of the apertures. A population of insect pupae suspended in a liquid is dispensed into the set of channels via an inlet. As the liquid flows through the system, it is distributed among the set of channels, ultimately exiting via the apertures into a set of catch basins.

Abstract: A continuous sieving apparatus is described. The continuous sieving apparatus includes a sieve surface attached to a wall. A set of openings is formed in the sieve surface so as to define a set of pathways extending through the sieve surface. The set of opening are defined by a length dimension that is greater than a width dimension. An action system is configured to move the sieve surface in one or more directions (e.g., horizontally and vertically). Such movement causes a first pupa having a first cephalothorax width that is less than the width dimension to move through any one of the set of openings, and a second pupa having a second cephalothorax width that is greater than the width dimension to be prevented from moving through the set of openings.

Abstract: A continuous sieving apparatus is described. The continuous sieving apparatus includes an inclined sieve surface attached to a wall. The inclined sieve surface is inclined with respect to a horizontal axis for pupae to continuously flow across down the incline. A set of openings is formed in the sieve surface so as to define a set of pathways extending through the sieve surface. The set of opening are defined by a length dimension that is greater than a width dimension. When the inclined sieve surface is submerged in a liquid, a first pupa having a first cephalothorax width that is less than the width dimension is free to move through any one of the set of openings, and a second pupa having a second cephalothorax width that is greater than the width dimension is prevented from moving through the set of openings.
