A beverage filter cartridge comprises an outer container with an access opening. A filter element is received in and configured and arranged to subdivide the interior of the container into first and second chambers. A beverage medium is stored in the first chamber. A lid closes the access opening. The lid has a first section overlying the first chamber and a second section overlying the second chamber. The first section of the lid is yieldably piercable to accommodate an inflow of liquid into the first chamber for infusion with the beverage medium to produce a beverage. The filter element is permeable to accommodate a flow of the beverage from the first chamber into the second chamber, and the second section of the lid is yieldably piercable to accommodate an outflow of the beverage from the second chamber to the exterior of the cartridge.

The invention discloses sliding block mechanisms which are respectively used on a thrice quartered variable-pitch louver and a double dichotomy variable-pitch louver and a variable-pitch louver sliding block system with one of the two sliding block mechanisms. The variable-pitch louver sliding block system comprises gear torsion spring clutch turnover mechanisms, a base and a top cover, wherein the sliding block mechanisms are tightly adjacent to the gear torsion spring clutch turnover mechanisms, the sliding block mechanisms and the gear torsion spring clutch turnover mechanisms are all arranged on a rotating shaft of the sliding block mechanisms, each gear torsion spring clutch turnover mechanism comprises a fixing sleeve, a torsion spring, a torsion spring unlocking gear, a clutch gear and a fixing nut which are sequentially sleeved on the rotating shaft, and the torsion spring unlocking gears are connected with the sliding block mechanisms through a clamping part in a transmission way. According to the sliding block mechanisms and the variable-pitch louver sliding block system, which are disclosed by the invention, an existing sliding block mechanism and an existing variable-pitch louver sliding block system are improved, the problems that a torque transmission piece is not synchronous with a turnover drum, and ladder belts are easily abraded are effectively solved, and the sliding mechanisms are also suitable for the double dichotomy variable-pitch louver.

The robot includes manipulating arms 11, rotating joint sections 20 disposed at one end of the manipulating arms 11, a first and a second manipulators 12, 13 which lap over in two stages and are connected to the rotating joint sections 20 and respectively and independently rotate about the same rotating imaginary axis, wherein the rotating joint sections 20 includes a first connection member 14 having a hollow section 23 for leading manipulator control system lines 21, 22 to the first manipulator 12, and a gap section 24 formed by cutting part of cylinder with leaving definite length arc 29, and which is connected to the first manipulator 12 thereby rotating the same; a second connection member, disposed at the outside of the first connection member 14, and which is connected to the second manipulator13 thereby rotating the same; an annular member 26 freely rotatablely disposed between the first connection member 14 and the second connection member 15 and having a guiding member 25 for leading the manipulator control system line 22 to the second manipulator 13 via the hollow section 23 of the first connection member 14 and the gap section 24, and the manipulator control system line 22 is heldin a frame in a configuration with relaxation rate allowably following the rotation of the guiding member 25.

The invention relates to an electromagnetic clutch system, in particular to a self-returning electromagnetic clutch. Including: shaft coupling assembly, the shaft coupling assembly is divided into two groups, the shaft coupling assembly includes a shaft coupling and a reset piece, the two shaft couplings are arranged at the ends of the two shafts in an axially movable manner and rotate together with the shafts where they are located, the two shafts The ends of the two shaft couplings that are close to each other are the coupling ends, and the two shaft couplings move axially toward each other under the action of the electromagnetic drive assembly until the two coupling ends meet to realize the coupling; Axially separated under the action of the above-mentioned reset member, and the coupling is disconnected; the electromagnetic drive component is gap-fitted on the outer periphery of the boundary between the two sets of coupling components, and the electromagnetic adsorption component is energized to form a magnetic circuit. The magnetic circuit passes through the two couplings. It solves the technical problem that the electromagnetic adsorption assembly of the electromagnetic clutch in the prior art rotates with the shaft, which is not conducive to connecting an external power supply, or that the built-in power supply leads to complex structure, increased volume and quality.
