摘要:
The invention relates to a terminal block with a handle. The terminal block includes an insulative base, a conductive terminal, a flexible clamp and a toggle member. The insulative base has a chamber and an insertion hole communicating with the chamber. The conductive terminal is fixed at a bottom of the insertion hole. The flexible clamp is received in the chamber and extended with a movable elastic arm abutting against the conductive terminal and closing the inserting hole. The toggle member has a pivot rotatably connected in the chamber. The pivot is extended with a pusher abutting against the movable elastic arm. When the toggle member is rotated to a release position, the pusher is rotated about the pivot to press the movable elastic arm so the movable elastic arm deviates from the conductive terminal and the insertion hole is opened.

A microfluidic electrochemical device and process are detailed that provide chemical imaging and electrochemical analysis under vacuum at the surface of the electrode-sample or electrode-liquid interface in-situ. The electrochemical device allows investigation of various surface layers including diffuse layers at selected depths populated with, e.g., adsorbed molecules in which chemical transformation in electrolyte solutions occurs.

In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. Embodiments for TLC plates and related methods are also disclosed.

Methods and apparatus relate to the synthesis of high fidelity polynucleotides and to the reduction of sequence errors generated during synthesis of nucleic acids on a solid support. Specifically, design of support-bound template oligonucleotides is disclosed. Assembly methods include cycles of annealing, stringent wash and extension of polynucleotides comprising a sequence region complementary to immobilized template oligonucleotides. The error free synthetic nucleic acids generated therefrom can be used for a variety of applications, including synthesis of biofuels and value-added pharmaceutical products.

A power socket temperature alarm device includes a casing, a power socket module received in the casing, a plurality of temperature detection elements, a processing circuit module, at least a lighting alarm element, and at least a sound alarm element. The temperature detection elements are set in contact with the power socket module and the temperature detection elements are in information connection with the processing circuit module. The processing circuit module is operatively connected with the lighting alarm element (for indicating the site of a hazard) and the sound alarm element (for giving off a signal of the hazard). When the power socket module receives a plug inserted therein and supplies electrical power thereto, the temperature will be gradually increased and the temperature detection elements are separately activated. Status variation of the temperature detection elements activates the processing circuit module to give off flashing light and mutually different sounds.

A block ring for a tube assembly for a reverse osmosis filter cartridge has multiple block segments connected to each other into a loop; any two adjacent ones of the block segments pivotally connected to each other, and outer ends of two of the block segments detachably abutting each other. For assembling, the block ring that is not formed into a loop yet is mounted into an outer annular groove of a tube body, and then the two block segments are rotated to make the outer ends abut each other. Thus, the block segments are braced transversely to securely abut the outer annular groove. Therefore, the block ring is securely mounted in the tube body. Besides, the block ring is integrated axially, such that the block ring can effectively and axially bear the outward abutting of a bearing plate, which prevents the block ring from deformation and enhances the safety.
