Core fiber detecting method and device in core yarn spinning
The presence/absence of a core fiber in a core yarn is reliably detected to prevent production of a core fiber-free core yarn. In a method for producing a core yarn C by wrapping a fiber bundle S around a core fiber F, the core yarn C is spun with a core fiber F content being changed from that of normal spinning for a predetermined time period after the start of spinning, in order to detect whether the core fiber F is present. The core yarn C may be spun with a core fiber made of a drawn elastic yarn to detect whether the core fiber is present based on a thickness fluctuation of the core yarn that is caused by slackening the core yarn. |

Flared leg precast concrete bridge system
A concrete building system includes a set of parallel spaced apart strip footers and one or more precast concrete sections supported by the footers in a predetermined alignment. Each precast concrete section has a top slab integrally connected to a pair of equally flared legs. Each leg depends from an end of the top slab at an effective flare angle to form a corner. The precast section includes haunch sections formed between the top slab and each leg resulting in a corner thickness greater than the uniform thickness of the angled leg to which it is integrally formed and the top member. The length of the effective span of each section varies between 60 and 90 percent of the distance between the bottom-of-leg span. The sections can be used to construct bridges, culverts, underground storage units, fluid detention units and dam structures. |

Foldable bed
A foldable bed having a frame and a cover attached to the frame. The frame has two handles, two identical side beams each having a pair of groove beams pivotally connected to one of the handles, connectors and bars pivotally connected to the handles or the connectors. The foldable bed is able to be folded by a simple action of pulling the handle upward meanwhile stepping on the peddling member. And it is able to be expanded by a simple action of breaking off the two groove beams with two hands of a user. Furthermore, the foldable bed occupies relatively small storing space when folded since a width of the folded bed is much shorter than that of the expanded one's. |

Soap-dispensing faucet structure
A soap-dispensing faucet structure comprises an upright cylindrical faucet body, having a spout extending outwards at the front side, and a tube seat at one side of the lower section to which a core shaft, a locking cap, and a faucet handle are sequentially mounted thereto. The upper section of the faucet has an appropriate-depth receiving chamber to which a sleeve cover and a pump device are combined to form an individual soap-receiving accommodation space. The lower section of the faucet has a set of cold and hot water ducts and an outlet tube that are fluidly connected to the core shaft of the tube seat to provide another individual water-discharging chamber linked to the spout to form a water influx-and-outflow circuit to be switched on and off by the faucet handle, providing a concise and whole depth-extending visual effect, and easier assembly and maintenance of the soap-dispensing faucet thereby. |

Collapsible potty
A collapsible potty comprises a one piece, rigid seat with a central hole through it. A pair of opposed tracks on the seat lower surface extend from front to rear. Left and right support panels are pivotally attached, by means of support hinge knuckles, to seat hinge knuckles on the seat left and right ends, respectively. Hinge pins engage hinge holes in the knuckles. The support panels are able to pivot from a folded position adjacent the seat lower surface, to an open position extending downward.A flexible, sealable waste bag hangs beneath the seat to receive waste. A tray has a plurality of hooks, arrayed around a central hole, that engage holes in the waste bag. The tray slides into the seat tracks to position the tray central hole directly beneath the seat central hole. A zip-lock closure seals the waste bag.A resilient locking arm on the seat hinge knuckle expands into a notch in the support hinge knuckle when the support panel is rotated into the open position, to hold the support panel open. A pushbutton release member moves the locking arm out of the notch to release the support panel for folding. |

Vacuum sewer system
Disclosed is a sewer system including a sewage receptacle, sewer piping connected to the sewage receptacle by means of a discharge valve, a mechanism for generating vacuum in the sewer piping, and a control mechanism for controlling the discharge valve. In order to achieve a more rapid closing of the discharge valve after discharge of the sewage from the sewage receptacle, the vacuum sewer system further comprises an aeration device in direct fluid communication with the discharge valve. The control mechanism is arranged to control the aeration device. Also disclosed is a discharge valve (2) for such a vacuum sewer system. |
