Simplified rear suspension for a bicycle or the like

A simplified rear suspension for a bicycle or the like comprises a wishbone seatstay structure. The wishbone structure is provided with a first extension extending toward the seat junction. A low friction guide component, for example a spherical element, is provided at the distal end of the extension. A second extension is provided at the seat junction, with a hollow interior for receiving the guide component. The guide component slides with little friction and play within the hollow interior. A stop member may also be provided within the hollow interior, stopping travel of the guide component under load. Motion of the rear wheel (via dropout) relative to the main frame (e.g., from the terrain) is translated into motion of the guide component within the hollow interior. The chainstays, in a pivotless arrangement, provide a moment which acts as a spring, resisting the motion of the dropouts and providing shock absorption and / or damping for improved ride and control.

Luggage Weight Threshold Indicator

InactiveUS20120006600A1Quick and easy in-terminal weight checkEasily and quickly checkWeighing apparatus detailsSpecial purpose weighing apparatusTorsion springEngineering
An integral weighing device for determining whether the weight of a luggage container and its contents exceed a maximum allowable amount simply by suspending the container by its handle. If the container weighs more than a set amount the integral weighing device provides a visual cue that the container exceeds the predefined weight. The integral weighing device comprises a torsion spring mounted within a housing, and a cord attached to each end of the torsion spring and fed via a guide-way through and out of the housing to an externally accessible grip handle. An indicator arm is rotationally mounted to the housing. When a person lifts the luggage by the grip handle the force is transferred to the torsion spring causing angular deflection toward the indicator arm. If the container exceeds the set weight the indicator arm provides a visual cue that the bag exceeds the predetermined weight.

A decorative double-sided jewelry clasp for joining two ends of a jewelry chain together. The clasp comprises a rocker plate pivotally mounted to a base plate at a hinge. The hinge is formed by cooperating yokes extending from the center of each of the rocker plate and base plate. With plates facing, the yokes align and a pin is inserted there through to pivotally secure them together. A torsion spring is carried on the pin to bias the rocker plate versus the base plate. Further, the base plate has a short post at one end and a longer hook at the other, the hook looping around to the backside of the rocker plate, and thereby stopping counter-pivoting of the rocker plate. Both hook and post catch and secure the ends of the jewelry chain, with the spring locking the chain at both ends until a user depresses the rocker plate, thereby counter-biasing it open at both ends to release the chain.

Sequential air sampler with filter cassette magazine

A sequential air sampler is provided having a rotatable carrier adapted to support filter cassettes received from a supply magazine at a load station, transport them to a sampling station where gas flow is directed through that cassette, and then be transported to an unload station to be received by a storage magazine. A Geneva driver operated by a single motor provides intermittent rotation to the carrier between fixed positions. A cam rotates in concert with the Geneva driver so that a follower in reciprocating motion pushes up and then pulls down a pair of plungers for simultaneous cassette loading and unloading whenever the carrier is at one of its fixed positions. Magazines have magnetically actuated stoppers to keep the stack of cassettes in place until released. Magazines may also have a retaining lid with a position-adjustable piston to secure cassettes for transport.
