Abstract: The invention relates to an acrylic structural adhesive composition containing (meth)acrylate monomers at least 20% of which is a mixture of 1,3-Dioxan-5-yl methacrylate and 1,3-Dioxolan-4-ylmethyl methacrylate, as well as block copolymers, elastomers and particles formed of a thermoplastic shell and an elastomeric core.

Abstract: A moon gear assembly is provided that includes a moon arm assembly having a driving moon gear. A pivot pin is connected to the moon arm assembly, and an adjustment arm is connected to the moon arm assembly. The moon arm assembly may also include a body that defines a chamber, a worm gear disposed in the chamber and arranged to interact with the driving moon gear, and a motor disposed in the chamber and couple to the worm gear.

Abstract: In one example, a transmission is provided that includes a sheave of selectively variable configuration, a driven member configured to engage the sheave, and a plurality of drive members configured for radial movement to selectively engage the driven member. The transmission may be operable in one or more of the following modes: traction mode, integer mode, IN mode, and infinite mode.

Abstract: Systems, devices, and methods for delivering a biological material into an organelle of a cell are provided. In one aspect, for example, a method for introducing biological material into an organelle of a cell can include bringing into proximity outside of a cell a lance and a preselected biological material, charging the lance with a polarity and a charge sufficient to electrically associate the preselected biological material with a tip portion of the lance, and penetrating an outer portion of the cell with the lance and directing and inserting the lance into the cell but outside of the organelle. The method can further include discharging the lance to release at least a portion of the biological material, charging the lance with an opposite polarity and charge sufficient to electrophoretically drive at least a portion of the biological material into the organelle, and withdrawing the lance from the cell.

Abstract: The invention relates to composition for an acrylic structural adhesive containing a mixture of block copolymers containing styrene and an elastomer.

Abstract: Transmission systems, assemblies, and components are described. In particular, aspects of the present disclosure relate to an infinitely variable transmission that maintains constant tooth engagement during changes in gear ratio. In one aspect, a transmission includes an axially movable sheave coupled to a chain. The sheave rotates around a drive axis. At least partially within the sheave is a set of moon gears. The moon gears orbit around the drive axis and are rotatable around respective internal axis. As the sheave moves axially, the chain and the set of moon gears move radially to define different gear ratios, with the gear ratios being changeable in infinitely small increments. A synchronization system moves the set of moon gears radially to correspond to the axial position of the sheave. A correction system optionally controls rotation of the moon gears to rotate teeth of the moon gears into alignment with the chain.
