摘要:
The invention relates to an aqueous sizing composition comprising (a) an emulsion comprising an alkenylsuccinic anhydride component containing alkenylsuccinic anhydride particles suspended in a first starch component containing emulsifying starch selected from the group consisting of non-ionic starches, ionic starches, and mixtures thereof, and (b) a second starch component selected from the group consisting of non-ionic starches, ionic starches and mixtures thereof, such that the alkenylsuccinic anhydride and the starch in the emulsion and the second starch component are present at a starch: alkenylsuccinic anhydride weight ratio that is sufficiently high to enable the sizing composition to impart useful sizing properties to a fibrous substrate when the sizing composition contacts the fibrous substrate. The invention also relates to fibrous substrates treated with the sizing composition, processes for making the composition and processes for using such a composition, and other compositions. In one embodiment, alkylene ketene dimer is used instead of alkenylsuccinic anhydride.

A lighting system includes a lens element which redirects light emitted from a display screen onto a keypad, keyboard or a control pad placed in front of or adjacent to the display screen such that without disturbing the display of other information on the display screen, the light emitted by the display screen illuminates the keypad, keyboard or control panel without the need for auxiliary light sources or auxiliary power sources. A simple program or program modification controls the display screen to provide appropriate light to the lens element.

摘要:
A power transmission system used in connection with a vehicle power wheel of a bicycle or other vehicle which has a fixed axle and which utilizes a rotating chain sprocket engaging an endless chain for receiving an input torque and transmitting an output torque. The system includes a transmission ratio varying apparatus that is operably connected to the wheel by the endless chain. The transition ratio apparatus incorporates a drive collar fixedly secured to a sprocket and having one or more input and output drive rings. A drive body is displaceable with respect to the input and output drive rings and includes input and output pawls pivotally connected to the drive body and engageable with the input and output drive rings. A shifter housing is moveable with respect to the fixed axle cam to rotatably shift the drive body with respect to the drive ring and change the relationship between the input and output pawls and thereby vary the torque transmission ratio. An operator lever and a cable connecting the operator lever with the shifter collar functions to move the shifter housing with respect to the fixed axle cam.
