Abstract: In a reaction where a lower hydrocarbon is subjected to direct decomposition by using a catalyst to produce a functional nanocarbon and hydrogen, the lower hydrocarbon is subjected to the reaction in an coexistent gas comprising low concentration of oxidizing gas, reducing gas or a mixture thereof. The precursor of functional nanocarbon produced on the catalyst and amorphous carbon secondarily produced on the catalyst react with the coexistent gas so that being removed from the catalyst, making it possible to prevent the drop of conversion with time on stream due to the inhibition of the reaction by the precursor and by-product. In the case where the raw material of lower hydrocarbon is biogas, the coexistent gas can be easily contained in methane by lowering purification degree of methane. Further, hydrogen can be obtained as one of decomposition products of lower hydrocarbon thus can be contained in methane during the reaction.

Title: Method and detection system for monitoring the speed of a lift cage
Inventor: ECKENSTEIN RUDOLF
IPC: B66B5/04
Filed: 2006-04-19
Granted: 2014-06-17
Abstract: In this method the speed of a lift cage is monitored. In the case of excess speed caused by brake failure of the motor brake or shaft fracture of the drive pulley shaft the safety circuit is opened and the detection system is transferred from the normal operational state (circle with a 1) to the retardation state (circle with a 2) in which it is monitored whether the lift cage is retarded after defined speed presets. After a successful retardation the detection system is transferred to the state of standstill monitoring (circle with a 3) in which it is monitored whether the lift cage leaves its standstill position. If the presets of state 2 or state 3 are not fulfilled, the detection system is transferred to the braking state of the brake (circle with a 4) in which a brake which fixes the lift cage is activated.

Abstract: Embodiments of the present invention generally relates to methods and apparatus for operating an artificial lift well. In one embodiment, the well is operated between an on cycle and an off cycle. Preferably, the off cycle is determined by detecting an increase in the pressure differential between the casing pressure and the tubing pressure. In another embodiment, the well is optimized by measuring the production of the well in one cycle of operation. The measured production is compared to the production of a previous cycle. A controller then optimizes the well based on the increase or decrease of the production from the previous cycle.

Abstract: An improved tool assembly for enhancing the surface of a heat transfer tube is provided. The tool assembly includes rods having cutting tips and positioned in rod guides which are slidably positioned in shafts provided in a tool holder. In an equilibrium state, the cutting tips do not extend from the tool holder. When a force is applied to the rod guides, the rod guides move in a first direction along the shafts in the tool holder, resulting in exposure of the cutting tips which enhance the tube surface. When the force is removed from the rod guides, the rod guides move along the shafts in a direction opposite the first direction to retract the cutting tips within the tool holder. In this way, the cutting tips are protected when not in use.
