Opinion

Rioi-t, Judge.

This appeal is from the decision of the Patent Office Board of Appeals affirming the rejection of claims 1-12 in appellant’s application serial No. 399,783, filed September 28,1964, for feedback quality control mechanisms and methods. We affirm.

The Subject Matter Claimed

The claimed invention regulates the operation of quality control equipment to produce a desired number of control actions per unit of time. The purpose of this regulation is to insure maximum utilization of available, on-line, quality-control equipment and operators. This purpose is accomplished by a feedback mechanism which regulates the sensitivity of defect-detection equipment. If a relatively large number of defects pass the defect-detection equipment during a given time period, the severity of the defects not corrected will be relatively high, and if a relatively low number of defects pass the defect-detection equipment during a given time period, the severity of the defects not corrected will be relatively low. In any event, the product is as good as it can be for a given amount of quality control equipment and number of operators without interrupting production.

Appellant’s specification relates his invention to the processing of yarns in the textile industry. Fig. 1 is schematic diagram of an essentially electrical embodiment of appellant’s invention as it might be employed in that industry. Fig. 2 is a schematic diagram of an equivalent [979]*979electro-mechanical embodiment of appellant’s invention. Fig. 1 is reproduced below:

I- - — I fig.l

In this figure, the right-hand units 1, 1', and 1" contain the quality-control and defect-detection equipment, while the feedback mechanism is made up of the single unit to the left of the bus bars 4,19, 30, and 27 and the transistors 15 in units 1,1', and 1". In unit 1, 3 is the yarn, 2 is the defect-detection equipment (or “quality sensing element,” as appellant terms it), which is a pair of condenser plates between which the yam passes, and 16 is a “cutter” which is apparently representative of the quality control equipment to be regulated. In the feedback mechanism, 7 is an impulse transmitter which produces a signal having an adjustable number of impulses per unit of time, 8 is a “combination means * * * in the form of a converter,” and 9 is a step motor which [980]*980converts the impulses which it receives from the combination means 8 into angular rotation of the potentiometer tapping arm 14 of the potentiometer 13. The other branch of the feedback mechanism consists of a transistor 15 in each of the yam clearers 1, T, and 1" which “acts as a switch to control the passage of an error correcting defect signal,” a resistor 17, and a “circuit element 18 which is comprised by a pulse former serving to transform the voltage drop across resistor 17 into pulses comparable with those coming from the datum signal impulse transmitter 7.”

The impulse frequency of the impulse transmitter 7 is preset to the maximum rate of yarn cutting which can be handled by the available continuity-restoring equipment and operators without interrupting production. Impulses from this source are transmitted to step motor 9 so as to move potentiometer arm 14 clockwise which increases the sensitivity of quality-sensing elements 2, 2', and 2". However, increased sensitivity of those elements results in increased yam cutting by cutters 16. Whenever a cutting action takes place, a signal occurs across resistor 17 and is transformed by circuit element 18 into a pulse which is delivered to step motor 9 so as to move potentiometer arm 14 corni-terclockwise, thereby decreasing the sensitivity of the quality-sensing elements. This negative feedback arrangement is said to “insure production of the highest quality yarn which the equipment can efficiently produce.”

Apparatus claims 1 and 7 and method claims U6 are generic to both the essentially electrical and the electro-mechanical species disclosed in the specification, apparatus claims 2 and 10-12 are drawn to the essentially electrical embodiment of Fig. 1, and apparatus claims 3, 8, and 9 are drawn to the electromechanical embodiment of Fig. 2.

The Refections

I. Claims 1-12 were rejected under the first paragraph of 35 USC 112 “as based on an inadequate disclosure.” The solicitor has specifically disclaimed reliance on a “best-mode” theory, apparently interpreting this rejection as having been predicated on the how-to-make and how-to-use requirements.

II. Claims 1,4, and 7 were also rejected under the second paragraph of 35 USC 112 “as indefinite.”

III. Additionally, the examiner stated that “A new title which is aptly descriptive of the invention claimed is required” and that

In Figs. 1 and 2, block 17 must be drawn as a resistor. Each, block 1, 7, 8, 18, 25, 28, [and] 33 must be labelled inasmuch as they do not symbolize conventional elements.

While the board did not “affirm” the examiner’s objections to appellant’s title and drawings, it did not disapprove of them, and appellant [981]*981now asks us to do so. Appellant apparently bases this request on Rule 196(a), Rules of Practice in Patent Cases.

OPINION

I. The Rejection Under the First Paragraph of § 1TB

There appear to have been several rationales for this rejection. First, and most generally, the examiner criticized appellant’s specification because it states repeatedly that the teachings therein will “insure production of the highest quality yarn,” or words to that effect, although appellant had admitted that the use of either embodiment might result in “a production run of poor quality.” In response to that criticism, we quote the relevant passage from the specification in its entirety:

Another object of the invention is to provide improved quality control for yarn cleaning equipment in wbieb the sensitivity of the quality control equipment is automatically regulated to insure production of the highest quality yarn which the equipment can efficiently produce. [Emphasis ours.]

The specification makes it abundantly clear that what appellant is trying to do is to make certain that the available, on-line, quality-control equipment and personnel will be used with maximum efficiency even though the product may still be “poor” if insufficient equipment and personnel are available. Accordingly, we do not agree with the solicitor that, “In that sense, the specification is clearly misleading or deficient.”

More specifically, the examiner criticized the specification for “failing to define the ‘combination means’ [8],” stating that “The term ‘combination means’ does not describe a specific embodiment but merely a ‘blank box’ capable of combining two signals and is not seen to comply with the requirement of Rule 71.”1 The board extended this rationale to members 1, 2, and 18.2 Appellant relies on United States [982]*982■patents to Jucker, Gith, Leopfe, "Wilson, and Wick et al. (all of which were “made of record” in the examiner’s first action) as evidence that circuitry for components such as 1, 2, 8, and 18 was so well known in the art as of his filing date that its disclosure in his specification is not required by the first paragraph of 35 USC 112.
