摘要:
This disclosure relates to a pre-assembled fastener assembly having a retainer, a nut member, and a cold expansion mandrel that is forcibly removable after the assembly is installed into an opening of a structural workpiece. The mandrel is captured between a portion of a retainer and a portion of a nut member. The forced removal of the mandrel expands the retainer into the opening, securing the fastener assembly therein. The assembly may also include a cap coupled to the retainer to seal the opening in the structural workpiece. The nut member can be fixed or free-floating with respect to the retainer. In addition, the nut member can be threaded to receive a fastener. The mandrel is recyclable or disposable.
摘要:
A sealed attachment fastener assembly with a receiving member and a cap that can be inserted into an opening in a work piece and fixed therein from only one side of the work piece. A portion of the fastener assembly on the blind side of the work piece is collapsible into a flange. In addition, another portion of the fastener assembly is contemporaneously radially expandable within the opening of the work piece to at least rotationally secure the fastener assembly with respect to the work piece. The radial expansion will result in a high interference fit of the fastener in the work piece, which may enhance the fatigue of the installation. A cap completes the fastener assembly to substantially prevent fluid from leaking through the fastener assembly opening. The cap can be assembled with the receiving member after the internal threads within the receiving member have been machined.

A tubular fastener element is inserted into an opening in a wall until a flange at the trailing end of the fastener element is in contact with the wall. Then, an externally threaded end of a rod is inserted into a center opening in the fastener element from the flange side of the wall and is mated with internal threads in the fastener element beyond the second side of the wall. A tubular mandrel that surrounds the rod is moved into contact with the entrance portion of the center opening in the tubular fastener. The outside diameter of the mandrel is larger than the inside diameter of the center opening in the fastener element. The rod is retracted to cause a reduced thickness wall portion of the fastener element to collapse and form a second radial flange on the second side of the wall. The mandrel is forced axially into the center opening in the fastener element. This causes a tubular end portion of the fastener element that is in the opening in the wall to radially expand into tight engagement with the sidewall of the wall opening. It also cold expands the wall material surrounding the opening for fatigue enhancement of the wall material.

A composite board with a multilayer laminated facer is presented having a nonwoven, a first polymer layer, and a second polymer layer. The laminate may be printed on the nonwoven, on the upper surface of the first polymer layer or inverted printed on the backside of an applied film. A number of configurations for the polymer layers are disclosed. The laminate may include exposed fibers on the lower surface or the nonwoven may be saturated. A removable peel-ply may be included. By controlling the placement and thickness of the polymer layers it is possible to tailor additive in the polymers such as colorants, opacifiers, UV stabilizers, and fire retardants to improve quality and reduce costs. In an alternate embodiment of the present invention, a first polymer layer is applied to the topside of the nonwoven and the second polymer is laminated to the first polymer layer as a preformed film. The laminated facer is thermally or adhesively bonded to the composite board.
摘要:
Compositions including a bacterial species or a combination of bacterial species and methods of using those compositions are described. In some embodiments, use of the compositions prevents disease and/or promotes growth in an animal. In some embodiments, the animal is a turkey. In some embodiments, the composition is antibiotic-free.

Methods and apparatus for unified communication across circuit-switched and packet-switched network domains. In one embodiment, voice or data available in one domain (e.g., circuit-switched such as a PSTN) can be seamlessly forwarded onto another domain (e.g. packet-switched such as a WLAN). A bridge or intermediary device is used that is coupled to both the circuit-switched network and packet-switched network. This bridge device allows bidirectional operation and permits, for example, a user to receive a telephone call at a user's home network via a PSTN, and forward that telephone call or information related to that call over another network such as a local IP network (e.g. a WLAN) to the user, where the user can answer that call or otherwise receive information associated with the call on their primary user device (e.g., cellular phone).
摘要:
Electronic devices and accessories such as headsets for electronic devices are provided. A microphone may be included in an accessory to capture sound for an associated electronic device. Buttons and other user interfaces may be included in the accessories. An accessory may have an audio plug that connects to a mating audio jack in an electronic device, thereby establishing a wired communications link between the accessory and the electronic device. The electronic device may include power supply circuitry for applying bias voltages to the accessory. The bias voltages may bias a microphone and may adjust settings in the accessory such as settings related to operating modes. User input information may be conveyed between the accessory and the electronic device using ultrasonic tone transmission. The electronic device may also gather input from the accessory using a voltage detector coupled to lines in the communications path.

A single prong, multiple signal conducting plug and plug detection circuitry is provided. The plug may be electrically coupled to a stereo headset including a microphone. The plug may include four signal conducting regions arranged in a predetermined order along the length of the prong. Detection circuitry may be operative to determine whether a microphone type of plug (e.g., a four region plug including a microphone region and two audio regions, or a three region plug including microphone region and only one audio region) or a non-microphone type of plug (e.g., stereo plug) is inserted into the jack of an electronic device (e.g., mobile phone). Detection circuitry may also detect user activated functions performed in response to user activation of one or more switches included with the headset. For example, the headset may include a single switch for performing a function with respect to a microphone (e.g., end-call function).

As described herein vascular anchoring systems are used to position an implant in a vascular area such as a bifurcated vasculature with relatively high fluid flow, for instance, in an area of a pulmonary artery with associated left and right pulmonary arteries. Implementations include an anchoring trunk member having a first anchoring trunk section and a second anchoring trunk section. Further implementations include a first anchoring branch member extending from the anchoring trunk member. Still further implementations include a second anchoring branch member extending from the anchoring trunk member.
