NOTEBOOKS RINGS BINDERS
Technical Examples
- An interactive binder and platform system includes a remote multimedia source, a feedback unit electronically connected to the remote multimedia source, and a plurality of binders. Each binder includes a plurality of conductive pins and at least one fixed medium having a plurality of distinct circuits operatively connected to the binder and a plurality of touch points defining exposed portions of the distinct circuits. A transceiver electronically connected to at least one of the binders provides power to the at least one of the binders and transmits/receives signals to provide two-way communication between the remote multimedia source and the binders where selection of a particular touch point by a user electronically connects the distinct circuit associated with the particular touch point and the remote multimedia source, the output from the remote multimedia source associated with input sent to the remote media source by the selection of the particular touch point.
- Wafer area pressure rings used to confine plasma in plasma processing chambers which are manufactured with bores therein such that replacement of the pressure rings during routine or repair maintenance is significantly eased. The bores allows the pressure rings to be installed by simply aligning the bores under hanging adapters which are connected to the ceiling of the chamber, lifting the rings such that the hanging adapters enter the ring, turning or twisting the entire apparatus a miniscule amount, and then lowering the ring apparatus on the hanging apparatus, thereby locking the rings in place.
- A surgical wound retractor is adapted to dilate a wound to a desired diameter. The retractor includes first and second rings, each having a diameter greater than that desired for the wound. The first and second rings are adapted for disposition interiorly and exteriorly of the wound, respectively. A plurality of retraction elements is disposed in a generally cylindrical relationship between the first and second rings and extends through the wound to exert a radial retraction force on the wound that is dependent on the distance separating the first and second rings. Retraction elements, both distensible and non-distensible, are contemplated with appropriate attachment elements at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force.
- A disc brake for a motor vehicle having at least two axially stationary friction rings being connected to a rotatable hub. The disc brake comprises several brake pads cooperating with the associated friction rings during a braking operation. A favorable structural overall design of the disc brake is achieved by a brake caliper straddling all friction rings and the associated brake pads and including a first actuating device in a brake caliper portion that extends axially beside the friction rings, and a second actuating device that is arranged between two friction rings and acting axially on both sides. Said actuating device acts on the brake pads arranged between two friction rings and is arranged so as to be displaceable relative to the brake caliper.
- A freewheel hub device includes two locking rings with axial grooves formed in the locking rings and being essentially V shaped in cross-section. The groove walls of one locking ring form a first and a second wedge surface, and one groove wall of the other locking ring forms a third wedge surface. A roll holder with rolls, which extend into the grooves of the locking rings, is mounted in the locking rings. A hub is rotationally arranged in the roll holder (14) and has a circumferential surface for cooperation with the rolls. The locking rings and the roll holder are turnable relative to each other in a limited manner and can take three different setting positions relative to each other.
