Opinion

Lane, Judge.

This appeal is from that portion of the decision of the Board of Appeals affirming the rejection of claims 2, 16 and 17 of appellant’s application Serial No. 487,251, filed on September 14, 1965, entitled “Graphic Transducing System.”1 We affirm.

In appellant’s words, the subject matter on appeal relates to:

{An] automatic drafting system which is capable of producing automatically, or semi-automatically, a composite drawing from a given plurality of characters, ■e.g. straight lines, curves, etc.
Drafting is an art of antiquity. Over the last several hundreds of years, little change has been made to the actual technique of drafting, apart from certain refinements made to drafting equipment. In our highly organized society, the mechanics of drafting have become highly routined and repetitious, but nonetheless exacting. Since most ordinary drafting is so exacting, it is very time ■comsuming and, therefore, expensive.
Some attempts have been made to expedite drafting, such as pantograph and mechanical accessories, hut even these devices require skilled draftsmen, and •do not materially reduce the time required to produce a drawing.
I have found that most drawings require approximately 5 to 20 standard characters. A few of these characters are the straight line, the circle and segments thereof, and the ellipse. These standard characters are used with variations in size and disposition.
Accordingly, it is an object of my invention to provide means for either storing these standard characters in physical, photographic or electrical form, or for ■electrically generating signals corresponding to the desired character. The desired character is selected automatically from the storage or generating means and the character, or the signal representing the character, is translated into a [1179]*1179form capable of effecting the production of the character, m desired dimension and disposition, on the drafting medium.

One embodiment of the invention, elected for prosecution in response to the examiner’s requirement for restriction under the Patent Office Rules, is represented in Fig. 4 reproduced below:

The specification described the Fig 4 embodiment as follows:

The automatic drafting system may * * * take the form of an electronic system as shown in Mg. 4. In one embodiment of this arrangement, the basic characters are generated in the nature of signals which are converted into the desired graphical symbols.
A character generator control, comprising a plurality of switches 23 permits-selection of a desired character by operation of a particular switch. The switches are respectively connected to suitable generating circuits capable of generating signals which may be symbolically transposed into the desired character. By way of example, a basic oscillator circuit 24 is shown as one possible type of curve generating circuit. It is to be realized, however, that instead of physical generators, pre-recorded signals on cards, tape or drum may be utilized.
The generated signals are applied to amplifiers 25, 26 for amplification of the vertical and horizontal components of the signal, respectively. The outputs of [1180]*1180the amplifiers 25, 26 are applied to a translator 27 which converts the signals to servo or motor driving impulses.
A segment selector 28, comprising a variable control for a basic type of pulse blanking circuit 29, is connected to the translator 27 for blanking out predetermined segments of the generated signal. Signal generators, translators and blanking circuits are well known and further detailed description of these circuits is considered unwarranted.
The output of the translator 27 is connected to an' x-y plotter 31 using horizontal and vertical servos 32, 33, respectively, to move a trace pen along the curves determined by the translator.
A coordinate selector 34, of a push-button type (similar to an adding machine keyboard) selects an x-y position which will be a point related to the final position of the selected character.
The output of the coordinate selector 34 is connected to a plotting board 35 which biases the x-y plotter servos to position the character on a desired area or horizontal and vertical position of output. The plotting board 35 may instead be operated manually, if desired.
The plotting board comprises a horizontal and vertical impedance network 36 between crossover points, preferably resistance but may be inductance, capacitance, diode, etc., which produces voltages unique for each position.

The appealed claims read as follows:

2. An automatic drafting system, comprising a source of information corresponding to a plurality of predetermined drafting characters, the drafting consisting of a plurality of such characters and parts thereof, means coupled to said source for sequentially selecting information corresponding to desired characters, an output plotter means for recording graphically the characters corresponding to the selected information, and translating means coupled between said source and said output plotter for converting the character information into a form usable by said plotter, said output plotter means including means for selectively controlling the horizontal and vertical positions in which said characters are recorded.
16. An automatic or semiautomatic drafting system comprising a plurality of drafting symbols stored on a plurality of storage areas, means for selecting a desired area in a selected sequence, means for blanking unwanted portions of said [ ?] character, means responsive to said selecting means and blanking means for applying the characters and portions thereof stored in said areas to line producing means, said line producing means having a writing element movable over the positions of a writing medium to apply said characters and portions thereof to said line producing means anil means to selectively control the positions at which said characters and portions thereof are formed on said writing medium.
17. A process for automatically or semi-automatically drafting comprising the steps of storing a group of different drafting symbols so that each is selectively available, selecting said symbols in predetermined sequence, converting the form of said symbol so that it may be graphically recorded, selecting segments of predetermined symbols, and applying said converted symbols and said parts' of said ' converted symbols to a graphical recording medium in a controlled sequence and at selectable and controllable locations thereon to produce a drawing having a desired pattern of symbols and parts thereof. . '

■ Claims 16 and 17 were rejected by the examiner under 36 USC 112 as based on an inadequate disclosure. In addition, the examiner re[1181]*1181jected claim 2 along with claims 16 and 17 as not complying with Patent Office Rule 75(d) on the ground that the specification does not provide any antecedent basis for apparatus to preselect the sequence of certain operations. The board affirmed these rejections, treating the latter as based on 35 USC 112.
