Appeal No. 96-1835 Application 08/207,116 The invention relates to a fluid clutch. Claim 1 is illustrative and reads as follows: 1. A fluid clutch comprising a driving section, a rotation shaft rotatably driven by said driving section, a driving disc rigidly mounted to and rotationally driven by said rotational shaft, a casing in which said driving disc is incorporated and which is rotatably disposed around said rotational shaft as a center of rotation, such that a torque transmission gap is defined between said driving disc and the casing, and an oil filled in the torque transmission gap defined between said driving disc and the casing for transmitting a driving torque from said driving disc to said casing, wherein a non-rotatable oil supply pipe communicates from a location external of the casing into the casing and wherein an oil supply means is non-rotatably mounted to the portion of the oil supply pipe external of the casing for selectively supplying and returning said oil between the outside and the inside of said casing and for selectively increasing and decreasing the driving torque transmitted from the driving disc to the casing, said casing further including at least one breather extending through said casing between the torque transmission gap and atmospheric air for releasing gas from said torque transmission chamber when pressure in said torque transmission chamber exceeds a predetermined upper limit value and for enabling inflow of atmospheric air to said torque transmission chamber when pressure in the torque transmission chamber is less than a predetermined lower limit value. Claims 1, 2, 14, 18 and 19 stand rejected under 35 U.S.C. § 112, first paragraph, as being based upon a specification which purportedly fails “to provide an adequate written description of the invention” (answer, mailed June 13, 1995, page 3). The 2 2In the final rejection, claims 1, 2, 14, 18 and 19 were also rejected under 35 U.S.C. § 103. The examiner has since withdrawn all such prior art rejections (see the advisory action dated April 19, 1995). -2-Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
