Abstract: Solid alkali metal benzyl oxide compositions providing flowable solids, namely flowable powders and flowable granulates, and solid compositions containing the alkali metal benzyl oxide compositions in combination with additional components are disclosed. Methods of making the solid compositions and using the solid compositions are also provided. The solid compositions are particularly useful for making solid cleaning compositions, including degreasing compositions, that beneficially are PPE-free providing safety improvements over liquid formulations.

Abstract: A firearm suppressor includes a first section along an axis; a second section along the axis downstream of the first section, the second section having a second section twist rate; a third section along the axis downstream of the second section, the third section having a third section twist rate, the third section twist rate greater than the second section twist rate; and a fourth section along the axis downstream of the third section, the fourth section having a fourth section twist rate, the fourth section twist rate greater than the third section twist rate.

Abstract: Processes and systems for creating digital designs of patient specific dental appliances and parts thereof, such as dental bands and wires. After receiving an order for a dental appliance that includes data regarding the patient's teeth and optionally adjacent anatomy, the digital design of the dental appliance is automatically started by dental appliance design software using rules based logic. Thereafter, a human can continue, and in some embodiments complete, the digital design. Or the entire design can be completed by the dental appliance design software without any human intervention. The final digital design can then be used to create the patient specific dental appliance.
