Abstract: A bracket, which is adapted for retaining a mattress, includes two hinge bases for being mounted on a bed frame, two rotating members and a connector. Each of the rotating members has a pivot and a first coupling portion extending from the pivot and being substantially perpendicular to the pivot. The pivots are respectively connected with the hinge bases rotatably. The connector has a transverse portion and two second coupling portions respectively provided at two ends of the transverse portion and coupled with the first coupling portions. As a result, the connector can be easily dismounted from and mounted to the rotating members. When the connector is dismounted from the rotating members, the bed frame is conveniently wrapped and transported.

Abstract: An easy-installable bracket for retaining a bed mattress is provided. The bracket is adapted to be disposed on a bed frame having a head portion and a feet portion. The bracket includes two seats and a bracket member. Each of the seats has a bottom plate for fixed at the feet portion of the bed frame, and an arcuate portion extended from the bottom plate. Two passages are respectively defined between the arcuate portions of the seats and the feet portion. The bracket member has a vertical portion, two front-extending sections respectively extended from two bottom ends of the vertical portion toward the head portion of the bed frame, and two parallel rear-extending sections respectively extended from distal ends of the front extending sections toward the feet portion. The rear-extending sections are slidably received in the passages respectively.

Abstract: A voice-controlled vibration electric bed includes a bed base formed of a base support frame and movable frames, a power supply unit mounted at the bed base, a driver electrically connected to the power supply unit for driving the movable frames to move relative to the base support frame, a microcomputer-based control device electrically connected to the power supply unit and the driver, microphones installed in the bed base and electrically connected to the microcomputer, and a vibration device installed in the bed base and electrically connected to the power supply unit and also electrically connected to the control device either directly or indirectly such that the microcomputer matches the sound picked up by the microphones with a predetermined frequency range and controls the vibration device to vibrate subject to the matching result.

Abstract: A reheat burner arrangement including a center body, an annular duct with a cross-section area, an intermediate fuel injection plane located along the center body and being actively connected to the cross section area of the annular duct, wherein the center body is located upstream of a combustion chamber, wherein the structure of the reheat burner arrangement is defined by various parameters and the structure of the reheat burner arrangement is defined by various dependencies.

Abstract: The present invention relation to a burner for a combustion chamber of a gas turbine with a mixing and injection device. The mixing and injection device includes a limiting wall that defines a gas-flow channel and at least two streamlined bodies, each extending in a first transverse direction into the gas-flow channel. Each streamlined body has two lateral surfaces that are arranged essentially parallel to the main-flow direction, the lateral surfaces being joined to one another at their upstream side to form a leading edge of the body and joined at their downstream side to form a trailing edge of the body. Each streamlined body has a cross-section perpendicular to the first transverse direction that is shaped as a streamlined profile.

Abstract: A combined flow straightener and mixer is disclosed as well as a burner for a combustion chamber of a gas turbine having such a mixing device. At least two streamlined bodies are arranged in a structure comprising the side walls of the mixer. The leading edge area of each streamlined body has a profile, which is oriented parallel to a main flow direction prevailing at the leading edge position, and with reference to a central plane of the streamlined bodies, the trailing edges are provided with at least two lobes in opposite transverse directions. The periodic deflections forming the lobes from two adjacent streamlined bodies are out of phase.

Abstract: A multipurpose tote bag includes a detachable ground cover having an upper end, a lower end and two side ends disposed between the upper and the lower ends, and an attaching means positioned along the upper end. The tote bag also includes a tote member having a base member, a front portion and an opposed back portion extending from the base portion, and a pair of opposed side portions extending from the base portion and disposed between the front portion and the back portion. Either one of the front portion or the back portion includes at least one outside pocket member. The tote bag still also includes an attaching means positioned along an upper edge of either one of the front portion or the back portion that is complementary to the ground cover attaching means, for securing the ground cover to the tote member.

Abstract: A centrifuge (10) is provided with a cantilevered shaft (18) upon which the main drive rotor (26) is located. A bobbin (62) is attached to the planetary gear shaft (44), which is driven in planetary motion by the rotation of the rotor (26) and its toothed engagement with the shaft (18) of the cantilevered rotor. A flying lead section (72) extends from the bobbin (62) through an aperture in the cantilevered rotor (26). The arrangement provides a centrifuge structure which can handle higher rotational speeds while maintaining resolution. The flying lead section (72) provides a simple path for the inlet and outlet leads (84,86) which reduces dead volume and increases reliability. The bobbin (62) supports at least one coil (68). Rotor component (44) includes at least one bearing (50, 52).

Abstract: A machine for cutting and threading bicycle spokes (11) comprising a cradle (15) for receiving a spoke, a cutter mechanism (17) positioned to intersect and cut off the spoke at a predetermined point, and a thread rolling apparatus (56) positioned adjacent the cutter. By turning a handle (41) the cutter mechanism is actuated by an eccentric (54) and cam (32) to actuate a lever (24) and move a shear (20) past a stationary shear (19) and sever the spoke. Further turning of the handle causes a feed lever (66) to shift the spoke to a position to be contacted by a movable die (61) to complete the cutting and threading process.

Abstract: A brake device which can be mounted on such vehicles as a bicycle and includes a brake disc which is fixed for rotation with the hub between a backing plate and pressure plate stationarily mounted. An actuator is provided for moving the pressure plate toward the backing member to squeeze the brake disc therebetween and impart a braking action on the disc and hub.
