Abstract: An example apparatus of the present disclosure may include an end effector. The end effector may include a pair of actuator-driven fingers that each include a compliant tip. The compliant tips may be used to scoop underneath items as part of item manipulation.

Abstract: Apparatuses including compliant tips and methods of manipulating items using the compliant tips are described herein. An example apparatus may include a robotic manipulator and a pair of end effectors. One end effector may include a pair of actuator-driven fingers that each include a compliant tip. The compliant tips may be used to scoop underneath items as part of item manipulation.

Abstract: Described are techniques for fabricating one or more parts of a valve used in a liquid chromatography system. At least one of a rotor and a stator are provided. The rotor is included in the valve and has a first surface facing a stator. The stator is included in the valve and has a second surface facing the rotor. A pattern is formed in at least one of the first surface and the second surface. Forming the pattern includes compressing the at least one surface by applying pressure thereto causing displacement of material to form at least one groove.

Abstract: A direct gas-fired heating unit is provided which uses an axial-bladed fan for generating a main air flow through a burner unit. The burner unit has a dedicated combustion air blower supplying combustion air to the burner separate from a main air flow generated by the main fan. The burner unit includes a dedicated blower which draws a small volume of outside air as combustion air. Further, the burner unit may include bypass ports which allows for discharge of bypass air from the burner unit.
