A device for forming bow springs in a one-piece centralizer includes a swing arm that is configured to receive the one-piece centralizer. The device and process using the device include mechanically applying, with a press, an external load onto an un-formed bow spring positioned on a form of the swing arm. When the load is applied with the device, the un-formed centralizer is forced downward to allow the bow spring to take the desired form/shape/geometry, length, and height of a formed bow spring.

A roll bending machine includes a roller unit and a tension device. The roller unit rolls and bends a strip member at a rolling rate varying in a width-wise direction of the strip member. The tension device applies tension to the strip member after being rolled by the roller unit in a rolling direction of the strip member, thereby reducing compressive stress which usually result in formation of wrinkles on the strip member. This minimizes the probability of formation of wrinkles on the strip member.

A casing bead having a U-ish or J-ish shape comprises, consists essentially of, or consists of an item, e.g., sheet metal, formed in a bent shape. The shape is formed of a first section, followed by a second section, a third section, and a fourth section. Alone, the casing bead's first and fourth sections have interior uninterrupted facing surfaces, and the second section is substantially perpendicular to the first and fourth sections.

A flame port structure for burning a gas includes a first continuous spiral strip, a second continuous spiral strip and a first outflow passage. The first continuous spiral strip has a first side edge, a second side edge and a first plurality of annular segments, and the second continuous spiral strip has a third side edge, a fourth side edge and a second plurality of annular segments, wherein each of the first plurality of annular segments and each of the second plurality of annular segments respectively have two first longitudinal opposite surfaces and two second longitudinal opposite surfaces. The first outflow passage has a first defining wall formed on each of the first respective longitudinal surfaces from the first side edge to the second side edge. The first outflow passage is structured so that the gas produces a specific combustion.

The present technology is directed to adjustable shunts for treating glaucoma. In particular, some embodiments provide shunts having a plurality of individually actuatable flow control elements that can control the flow of fluid through associated ports and/or flow lumens. For example, each individually actuatable flow control element can be actuated to modify a flow of a corresponding port and/or flow lumen. The individually actuatable flow control elements may be actuated along a given actuation axis. A flow control assembly may include a plurality of flow control elements arranged about a collection region. Accordingly, the shunts described herein can be manipulated into a variety of configurations that provide different drainage rates based on a degree to which the ports and/or flow lumens are blocked or unblocked, therefore providing a titratable glaucoma therapy for draining aqueous from the anterior chamber of the eye.
