Title: Keyed, true-transparency image information combine
Inventor: FREEMAN RICHARD D
IPC: H04N5/272
Filed: 1992-02-05
Abstract: ABSTRACT OF THE DISCLOSURE       The disclosed keyed, true-transparency combine and keyer receive a plurality of image information signals Vi, each having a corresponding input key signal Bkj, over a respective channel. The image signals can be dynamically ranked in a defined prioritized order, even on a field-by-field basis. However, rather than switch the individual image signals as their prioritized order changes, the order of the channels is dynamically and switchably interchanged within a keyer means by switchably interchanging a plurality of substantially identical keyer units while generating a plurality ofprocessed true transparency image key signals Pki. The keyer units are substantially identical in the sense that, while there may be some structural distinctions among the keyer units, there is a commonality of function among the keyer units within a keyer means. The keyer means also generates any needed processed background key signals PkB. The respective keyer units are switchably changeable to produce true transparency processed key signals, which are generated such that processed key signal Pki for an i-th channel is produced by the i-th respective one of the plurality of substantially identical keyer units within the keyer means. The i-th keyer unit is adapted to modify the value of its input key signal Bkj with the values of the input key signals Bkj in the higher priority channels to generate a true transparency processed key signal Pki for the i-th priority channel. A keyer unit within the keyer means generates the true transparency processed image key signal Pki for the i-th image signal so that:       where B0 = 0 and so that Pk1 + Pk2 + ... + PkN + PkB = 1Ø The combiner also cuts each respective image signal Vj and background signal VB by its respective processed key signal and combines the plurality of cut signals to generate the special video effect of an image information combine Vc so that VC = Pk1V1 + Pk2V2 + ... + PkN VN + PkBVB.     In one case, using the input key signals, a key-taken signal can be generated by multiplying a key-requested signal and a key-available signal while a key-now-available signal can be generated by algebraically subtracting the key-taken signal from the key-available signal. In another case, also using the input key signals, a key-taken signal can be generated by algebraically subtracting a key-now-available signal from a key-available signal while a key-now-available signal can be generated by multiplying the key-available signal and another key signal, which other key signal is equal to one minus the key-requested signal. In either case, the generated key-now-available signal can be coupled from a higher priority i-th channel to a lower priority (i+1)-st channel as the key-available signal for the lower priority (i+1)-st channel and the respective processed key signal Pki can be produced in response to the key-taken signal.

Title: Locking arrangement for disconnect switch
Inventor: RAMOS JOEL A
IPC: H01H31/04
Filed: 1992-04-13
Abstract: An arrangement for locking the disconnect linkage of a high-voltage switch is provided that includes two relatively movable locking members that are each moved between locked and unlocked positions in response to operation of the disconnect linkage. As the disconnect linkage is moved to an opened position, the two locking members are moved into relative overlapping alignment to receive a blocking member to prevent movement of the disconnect linkage. One locking member is carried by the disconnect linkage and the second member is carried by a pivotally mounted support arm that is affixed to the disconnect linkage so as to move therewith. Accordingly, the second locking member does not encroach on the space adjacent the disconnect linkage except when it is moved into alignment in the opened position. The support arm that carries the second locking member is arranged to guide the disconnect linkage and prevents undesirable movement of the disconnect linkage due to transverse forces on the disconnect linkage during movement between the opened and closed positions.

Title: Passive indirect shutdown cooling system for nuclear reactors
Inventor: SPINKS NORMAN J
IPC: G21C15/24
Filed: 1992-04-22
Abstract: PASSIVE INDIRECT SHUTDOWN COOLING    SYSTEM FOR NUCLEAR REACTORS                                ABSTRACT   A nuclear reactor system including a main heat transport path around which a first coolant is pumped by main circulation pumps to transport heat from the reactor core to a steam generator. A heat exchanger is located in the main heat trans-port path after the outlet from the steam generator, the secondary side of that heat exchanger being in a decay heat removal loop which contains a second liquid coolant. A vapour separator in the decay heat removal loop is connected to an outlet of the heat exchanger with the vapour separator's outlet being connected to an inlet of a further heat exchanger located in a large tank of water which forms a heat sink. The further heat exchanger's outlet is connected to the heat exchanger's inlet forming a closed loop. The further heat exchanger is located at a higher elevation than the heat exchanger whereby a natural convection flow can occur in the decay heat removal path. Normally, the vapour/liquid interface in the loop is at a higher elevation than the heat sink which prevents any significant natural convection flow until boiling of the second liquid coolant occurs in the heat exchanger. If the steam generator is lost as a heat sink, this causes boiling of the secondary coolant to occur in the heat exchanger starting a natural convection flow in the decay heat removal loop. This natural convection starts automatically without the need of any valves being opened or any other type of intervention.

Title: Complementary-sequence pulse radar with matched filtering following doppler filtering
Inventor: URKOWITZ HARRY
IPC: G01S13/522
Filed: 1992-06-25
Abstract: Abstract of the Disclosure A radar generates first and second mutually complementary binary code sequences.  The autocorrelation functions of the first and second pulse sequences are selected so that, in the sum of their autocorrelation functions, the main lobes add, and the sidelobes are of equal amplitude and opposite polarity, and therefore cancel.  The radar sequentially transmits dispersed pulses in which the chips are phase modulated with the two codes.  The received pulses are applied uncompressed to the input of a doppler filter bank, which filters them into various Doppler channels, each representative of a particular radial velocity of the target.  Within each channel, the received signals modulated by the first code are matched-filtered by a filter matched to the first code, to produce a first time-compressed pulse, and those modulated by the second code are matched-filtered by a filter matched to the second code, to produce a second time-compressed pulse. The time-compressed pulses include a main lobe which represents the range of the target, and also include sidelobes which may introduce range ambiguity.  The first and second time compressed pulses are added together in each Doppler channel, to produce, in each channel, range pulses in which the range sidelobes are suppressed.  Thus, range sidelobe suppression is accomplished without the use of discrete range sidelobe suppressors.
