DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-7 are rejected under 35 U.S.C. 102(a)(1) as being unpatentable by Wei (CN 113459550).
Wei teaches a noise reduction tire, comprising a tire body and a sound-absorbing layer attached to the inner surface of the tire body.
The sound absorbing layer is bonded to the inner surface of the tire by means of a composite silicone, the composite silicone comprising, by weight percentage:
30%-60% of polydimethylsiloxane;
0%-3% of a pigment;
2%-8% of an alkoxysilane; and
0.5%-2% of a titanate; with the remaining being a filler;
the pigment can be one or more of titanium oxide, iron oxide, and carbon black; the alkoxysilane is one or more of methyltrimethoxysilane, ethyltrimethoxysilane, vinyltrimethoxysilane, methyltriethoxysilane, ethyltriethoxysilane, vinyltriethoxysilane, and aminopropyltriethoxysilane; and the filler is one or more of calcium carbonate, silica micropowder, aluminum hydroxide, and aluminum oxide.
The sound-absorbing layer is bonded to the inner surface of the tire by means of a composite silicone, the composite silicone comprising, by weight percentage, a composition A and a composition B;
the composition A comprises polydimethylsiloxane, a pigment and accounting for 30-60% by weight of the composition A, the pigment accounting for 1-2% by weight of the composition A, and the remainder of the composition A being the filler; and
the composition B comprises polydimethylsiloxane, an alkoxysilane, a pigment and a filler, the polydimethylsiloxane accounting for 20-60% by weight of the composition B, the alkoxysilane accounting for 10-20% by weight of the composition B, the pigment accounting for 1-2% by weight of the composition B, and
the remainder of the composition B being the filler.
The method comprises the following steps:
separately preparing the composition A and the composition B, and storing the composition A and the composition B in separately;
using plunger pumps to respectively pump the composition A and the composition B into a quantitative adhesive dispensing device;
the quantitative adhesive dispensing device injecting the composition A and the composition B into an adhesive mixing tube according to a preset volume ratio
for mixing same, the composition A and the composition B being mixed in an adhesive gun of the adhesive mixing tube, and the adhesive gun of the adhesive mixing tube being mounted on a mechanical arm;
controlling by programs the movement path of the adhesive gun of the adhesive mixing tube so as to coat the inner wall of a tire with the two-component silicone; and
by means of a track, inputting to the interior of the tire a sound-absorbing layer that needs to be attached, compacting the sound-absorbing layer onto the inner wall of the tire so as to fully attach the two, and then transferring the tire to a next station to wait for completing curing.
The adhesive gun extrudes an adhesive strip having a cylindrical cross section and a diameter of 0.1-15 mm, or an adhesive strip having other shapes with an equal area. There are at least two quantitative adhesive dispensing devices, wherein when one of the quantitative adhesive dispensing devices is dispensing the adhesive, the plunger pumps replenish an adhesive liquid in the other quantitative adhesive dispensing devices, such that the quantitative adhesive dispensing devices operate alternately to achieve a continuous quantitative output of the adhesive liquid.
Wei teaches an apparatus that comprises:
a first plunger pump, which is used for conveying the composition A,
a liquid inlet end of the first plunger pump communicating with a container
that contains the composition A, and
a liquid outlet end of same communicating with a quantitative adhesive dispensing device;
a second plunger pump, which is used for conveying the composition B,
a liquid inlet end of the second plunger pump communicating with a container that contains the composition B, and
a liquid outlet end of same communicating with a quantitative adhesive dispensing device;
a quantitative adhesive dispensing device, which has two liquid inlets and two liquid outlets, the two liquid inlets respectively communicating with the liquid outlet ends of the first plunger pump and the second plunger pump, and the two liquid outlets communicating with an adhesive valve;
an adhesive valve, which is provided with two inlets and one outlet, the two inlets respectively communicating with the two liquid outlets of the quantitative adhesive dispensing devices, and the outlet communicating with an adhesive gun of an adhesive mixing tube; and
an adhesive gun of an adhesive mixing tube, which is mounted on a mechanical arm and is used for discharging the adhesive liquid from the tube and attaching same to the inner wall of a tire.
There are at least two quantitative adhesive dispensing devices, the quantitative adhesive dispensing devices being connected in parallel to each other. There may be one quantitative adhesive dispensing device, the compositions stored in the quantitative device are quantitatively outputted until the storage amount of the compositions reaches an adhesive replenishment threshold position set by a system, and then the adhesive is automatically replenished by the program or manually replenished.
