20090041532 | READY LOCK RING BINDER MECHANISM - A ring binder mechanism that retains loose-leaf pages. The mechanism includes a housing and hinge plates supported by the housing for pivoting about a pivot axis relative to the housing. The mechanism further includes rings that hold the loose-leaf pages. Each ring includes two ring members. A first ring member is mounted on a first hinge plate and can move therewith relative to a second ring member.

In an open position, the two ring members form a discontinuous, open loop for adding or removing loose-leaf pages from the rings. Additionally the mechanism comprises an actuator that is pivotally mounted on the housing and can move relative to the housing for controlling the pivoting motion of the hinge plates and closing the ring members. A travel bar has a connection to the actuator for blocking the hinge plate's pivoting motion when the ring members are closed.

20130093307 | LED LAMP HAVING TWO LAYERS OF FLUORESCENT POWDER - An LED lamp has two layers of fluorescent powder, wherein a blue light of 400-530 nm emitted by a blue light LED chip first irradiates on an inner layer of silicate fluorescent powder to excite a light of a higher wavelength which is then emitted to an outer layer of YAG fluorescent powder, so as to obtain an ideal warm white light. The yellow light excited by the silicate fluorescent powder re-excites YAG fluorescent powder to obtain a warm white light having a higher color rendering index, while a light source with an area several times greater than that of the original chip obtained by exciting the inner layer of silicate fluorescent powder can re-excite the YAG fluorescent powder to multiply the excitation effect. | 04-18-2013 |
