Abstract: SIGNAL PROCESSING CIRCUIT     Abstract of the Disclosure A circuit having a "selected" and a "deselected" operating mode includes a controllable latch which is operable when the circuit is "deselected" and a controllable pulse generating network which is operable when the circuit is "selected". The latch senses and stores a signal evidencing a change of state of any one of certain input signals to the circuit when the circuit is deselected.  The pulse network is responsive to the stored signal and produces a pulse, indicative of the occurrence of a change, when the circuit is subsequently selected.

Abstract: ARTICULATING FRAME PRESS              ABSTRACT OF THE DISCLOSURE     A press for forming complementary parts including mold parts and metal stampings having an articulating frame is disclosed.  The press of the present invention comprises a first bolster plate and a second bolster plate which in a first position are spaced apart in a parallel opposed manner.  The frame may be articulated from the first posi-tion to a second position wherein the bolster plates are in a non parallel, non opposed arrangement.  The frame comprises a first pair of spaced apart frame supports pivotally collected at their ends to the first and second bolster plates, and a second pair of spaced apart frame supports having a length less than  the first pair of frame supports pivotally connected at their ends to the first and second bolster plates in a spaced apart manner.  The pairs of spaced a-part frame supports having unequal length, and the bolster plate to which the frames supports are pivoted form a four bar linkage mechanism which allows the bolsters to rotate relative to one another as the frame supports are articulated, A fixed platen And a movable platen are associated with the spaced apart bolster plates with  the parts of a separable mold or die affixed to the platen in a complementary manner when the frame is in the first position.  Swinging the press frame to the second position allows the lower half of the separted mold or die to be assembled to the platen with-out an overhead obstruction.  In the second position the upper platen is also accessible from overhead without obstruction.

Abstract: ABSTRACT          METHOD AND DEVICE FOR GENERATING CHECK BITS         PROTECTING A DATA WORD            Single error correction and double error detection with byte-wise generation of check bits.  The individual bytes of the data word are successively applied via a byte selection logic to a bit selection logic comprising gates which pass on to a byte parity generation logic the data bits required in accordance with the code used.  In this logic, one parity bit is generated to one respective switched data byte.  The parity bits of the individual successively switched bytes are summed up in an accumulation logic, and supply the desired check bit after the last byte.  The gates in the bit selection logic are controlled by a code implementing logic representing the respectively used check code.  An error detecting and localizing logic detects the type of error, and defines the error location in case of a single error.

Abstract: ABSTRACT OF THE DISCLOSURE         In a cable stayed bridge a continuous roadway slab includes an end span supported on and extending between an abutment and a tower and a middle span extending halfway between the tower and another tower.  Both the towers and the roadway slab are formed of reinforced concrete.  The roadway slab cantilevers outwardly on both sides from the tower.  The tower is constructed so that it can absorb approximately two-thirds of the bending moment from one sided live loads by redistributing the resultants of the vertical loads within its cross section.          Inclined stays extend between the tower and the roadway slab and includes first stays extending between the upper end of the power and the ends of the spans remote from the tower and second stays also extending between the tower and the roadway slabs, however, on the tower their ends are located below the upper end of the tower and on the roadway slab they are located between the tower and the end of the span to which the first stays are connected.  The first stays are constructed stronger relative to the second stays.  The roadway slab is formed as a plural hollow cell member of relatively low height constructed as a Vierendeel truss.

Abstract: ABSTRACT  A system for presenting a head-up display to the operator of a vehicle is disclosed.  This system comprises a light source fiber optic bundle (52) which is secured to the helmet of the vehicle operator and generates a light beam signal which travels at an angle proportional to the orientation of the pilots head and, accordingly, his line-of sight.  This beam is detected by a detector (68) which is optically coupled to the light beam and provides line-of-sight information at its output. A computer (96) receives the line-of-sight information together with other information and sends it via a cathode ray tube (112) and an optical coupler (14) to a beamsplitter (16) which provides that information to the operator of the vehicle while allowing the operator to see through the beamsplitter (16), thus providing the operator with additional information without obstructing his view.
