Opinion

BALDWIN, Judge.

This appeal is from the decision of the Board of Patent Interferences awarding priority as to all remaining counts in Interference No. 94,778 to Trifillis, the junior party.

The counts in issue, 1, 3, 4 and 5, correspond to claims 2, 6, 4 and 5, respectively of Trifillis patent No. 3,139,249, 1 copied in modified form in application Serial No. 368,519 2 by appellants Byrne and Cruger. That application is conced-edly entitled to the benefit of the filing date of its parent application, 3 filed prior to appellee’s filing date. No testimony was taken and the sole issue is whether the board erred in holding that appellants’ application does not support the counts.

Before us, appellants submitted the case on brief and appellee submitted on the record.

THE INVENTION

Appellee’s patent discloses airplane arresting apparatus including a cable or loop extended across a landing surface for engagement by a portion of an airplane as it lands. Each end of the cable is wound around one of two integrally formed drums of a two-drum reel to which a brake is operatively connected. The brake is of the fluid type, comprising an impeller coupled to the reel and disposed in a housing containing a liquid. As the cable is extended and the reel rotated thereby, the action of the impeller in the liquid produces a controlled braking action tending to stop the airplane which is landing. A retrieve unit, in the form of a fluid driven turbine, is also connected to the reel for rewinding the cable thereon.

*1391 Counts 1 and 4 are exemplary of the invention in issue:

1. An energy absorber unit comprising a compound reel, said reel having two integrally formed aligned winding drums, a loop formed from a coilable linear element, each end of the loop wound on one of the drums so as to leave an extended center arrest loop portion, said loop being reeved across a landing surface, a housing and liquid immersed impeller means in the housing operatively coupled to said reel during payout of said linear element ends therefrom, said impeller means rotating in said housing against the resistive action of liquid therein to retard the rotation of said reel caused by the unwinding of said ends of the loop from said aligned winding drums of the reel when the said loop is placed under load.
4. An energy absorber unit comprising a reel, said reel having aligned winding drums, a loop formed from a coilable linear element and having each end of the loop wound on one of the drums so as to leave an extended center arrest loop portion, said loop being reeved across a landing surface, a fluid brake operatively coupled to said reel, said brake being operated to retard the rotations of said reel caused by the unwinding of said ends of the linear element loop from said aligned winding drums of the reel when the said loop is placed under load, and a retrieve unit for winding the respective arrest loop ends onto said aligned drums, said retrieve unit including a fluid powered turbine driva-bly coupled to said reel to rotate the same in a reverse direction to the direction of rotation thereof during linear element payout independently of said brake.

APPELLANTS’ DISCLOSURE

Appellants’ application is directed to aircraft arresting apparatus 4 which includes a loop that extends across the runway for engagement by an airplane in landing, a reel to which the ends of the loop are attached, brake means for providing resistance to the rotation of the reel as the loop is being extended during a landing operation, and retrieve means for driving the reel to return the loop to its original position. The application discloses different specific structures for certain of these elements in what it designates as various embodiments of the invention.

While it is unnecessary to reproduce any of the figures of the drawings in this opinion, consideration must be given to the relationships of certain of those figures to the more pertinent “embodiments” which appellants describe. Thus, Figure. 1 shows what is described as a view of the “general organization” of the invention; Figures 2, 3, 4 and 5 are described as showing different views directed to “a preferred embodiment”; Figure 7 is stated to show “another embodiment”, and Figures 12 and 13 are said to be views “showing the use of a water brake in another preferred embodiment.”

The general organization of the invention illustrated in Figure 1 includes broadly the combination of elements specified above but does not reveal the details of the elements. It does disclose a jet turbine connected to the reel, and states that the turbine drives the reel in launching operations.

Turning to the first “preferred embodiment” of Figures 2, 3, 4 and 5, Figure 2 shows a schematic view of an overall system. The loop is disclosed as having each end wound upon one drum of a two-drum reel. The drums are designated 22A and 22B and are described as “coupled with an over-running clutch 22C to permit differential angular velocity between the two spools” (or drums). The arrangement allowing one drum to rotate faster than the other is described as important during off-center arrest- *1392 ments because it results in self-compensating adjustments to the center of the runway. Figure 2 additionally shows a brake, of the friction-type, operatively connected to each drum to provide a controlled resistance to unwinding of the loop. Also disclosed is a rewind motor, for which it is stated “a jet turbine 2 such as shown in FIGURE 1 could be substituted.” Figure 4, which is not described except for being identified as a front elevational view of “the launching and arresting engine shown in FIGURE 3”, also shows a reel including two aligned drums designated 22A and 22B spaced by a member designated 22C. Additionally, Figure 4 shows what conventional drawing practice would indicate is a key securing the two drums 22A and 22B rigidly to a shaft running therethrough. Figure 5 illustrates the arresting system generally and also shows a reel with two coaxial drums 22A and 22B coupled by the over-running clutch 22C disposed therebetween.

The embodiment illustrated in appellants’ Figure 7 differs from the first “preferred embodiment” primarily in that it uses a single drum reel with both ends of the loop wound thereon. A brake assembly is operatively connected to each side of the drum.

The embodiment of Figures 12 and 13 is said to “employ the principles of a water brake for the same purposes as set forth and described heretofore with respect to the embodiments of FIGURES 2 and 7”. The brake of Figures 12 and 13 comprises an impeller opera-tively attached to a single-drum reel and providing a braking effect by its action on water in a housing in which it is disposed.

THE BOARD’S DECISION

The board first found that the question whether appellants’ application supported the recitation of a reel having “two integrally formed aligned winding drums” (emphasis ours) in count 1 was properly before it. Thereafter ruling on the merits, it held that there was no support for that recitation.
