Abstract: Circuit of the invention detects/recognizes multi-frame synchronization bits of concurrently existing plural unknown kinds of multi-frame synchronization in a received signals of digital transmission. The above-­mentioned detection as well as recognition is carried out by software in place of wired logics of prior art. A micro processor (32) instructs a gate (22) to extract a specific bit out of received sequential bits. The extracted bit is inputted to a shift register (24) and outputted therefrom after delayed by the elapsing frame numbers via its respective output terminals corresponding to the delaying frame numbers. The outputted bit is compared with not-delayed inputted bit, and if they meet a predetermined format, the bit is recognized as of a multi-frame synchronization. The bit extraction is scanned over all the control signal bits, and the results are stored in a memory. By use of thus stored information, the processor recognizes the existing types of the multi-frame synchronization. Further more, based on thus stored information, the processor periodically monitors whether the synchronization is normal, an if it is stepping out, the synchronization detection procedure is repeated. The invention makes the circuits simple and flexible to recognize mixed kinds of multi-frame synchronization, without increasing the circuits, because it can be done by programming of the micro processor.

Abstract: Disclosed herein is an optical information reproducing apparatus having a phase difference tracking system which is free from an influence of a tangential phase different of output signals from a photodetector. The photodetector comprises first through fourth photocells which are respectively disposed at first through fourth quadrants defined by a first straight line parallel to an information track image and a second straight line perpendicular to the first straight line. Output signals of the first and second photocells are delayed for a specified time by respective first and second delaying circuits. Output signals of the first delaying circuit and the third photocell are added by a first adder, and output signals of the second delaying circuit and the fourth photocell are added by a second adder. A phase comparator produces a tracking error signal from a phase difference between output signals of the first and second adders. Alternatively, a first phase comparator produces a phase difference between the output signals of the first and second photocells, and/or a second comparator produces a phase difference between the output signals of the third and fourth photocells. At least one of output signals of the first and second comparator is used for producing a tracking error signal.

Abstract: A method and apparatus are disclosed for implementing an optical communication network wherein switchable information signals are retained in the optical mode. Sources of optical signals (291), destinations for optical signals (290), and intermediate photonic switches (200) are interconnected by optical links (13), each link comprising two unidirectional transmission optical fibers (135, 13N). An optical bit stream generated at a source of optical signals comprises repetitive time frames (3005). Each time frame includes a frame synchronizing signal (3001) and a plurality of signal groups of information bits (3003) separated in time by a route switching interval (3014). The optical bit streams entering a photonic switch are frame synchronized. A particular group of information bits retains its position in time within a frame from the source of the optical signal to its destination. The photonic switch is set up (234) during a route switching interval for transmission of a group of information bits from an input to an output of the photonic switch. Advantageously, in such a network optical signals need not be converted to electrical signals as they traverse communication links from a source to a destination.

Abstract: Farbbandkassetten für Schrieb- oder Büromaschinen ähnlicher Bauart unterliegen unterschiedlichen Konstruktionsforderungen, wobei sie vor allen Dingen mittels einer Einhandbedienung leicht austauschbar sein sollen. Da die Transportelemente z. B. für das Karbonband bei derartigen Kassetten mit in dem Gehäuse lagern, sind diese Kassetten sehr kostspielig. Um dieses zu vermeiden, sind Farbbandkassetten mit austauschbaren Farbbandspulen bekannt geworden. Der Erfindung liegt nun die Aufgabe zugrunde, eine Farbbandkassette mit nachladbaren Farbbandspulen zu schaffen, die einen einfachen und sicheren Austausch der Farbbandspulen und ein einfaches Befestigen des Farbbandes an dem Aufwickelkern (85) ermöglicht. Dieses wird dadurch erreicht, daß die Aufnahmespule (15) mit einer Lagerbohrung (117) um einen Lagerzapfen (14) und mit einer Lagerfläche (118) auf einer Auflagefläche (81) drehbar gelagert ist, welche dicht unterhalb der Aufnahmebohrung (86) für das Befestigungselement (92) angeordnet ist. Hierdurch und durch weitere Ausbildungen wird das Einfädeln und Befestigen des Farbbandes (29) an dem Aufwickelkern (85) sehr erleichtert.

Abstract: An automatic frequency control circuit (AFC) (10) is disclosed for use in a television receiver the latter of which includes a local oscillator (LO), an intermediate frequency (IF) demodulator section, and a phase locked loop (PLL) for acquiring and phase locking onto the IF signal. The AFC circuit comprises an acquisition circuit (72) for sensing and detecting a no signal condition, an out of lock signal condition and phase locked condition. During a no signal condition the acquisition circuit enables offset (76) and clamp (70) circuits for respectively setting the nominal operating frequencies of the voltage controlled oscillator (VCO) of the PLL and the LO to the center frequency of the IF passband. Upon appearance of an IF signal the acquisition circuit enables a sweep circuit (78) as the receiver is in an out of lock condition in order to sweep the VCO downward from the passband center frequency to just above the sound carrier frequency and then sweeps the VCO frequency upwards toward the video carrier frequency. During the downward sweep of the VCO the acquisition circuit disables the phase detector of the PLL to inhibit spurious lock up. Upon the VCO phase locking to the IF signal the clamp, sweep and offset circuits are disabled while the phase detector is enabled.

Abstract: A safing and arming (S&A) device 20 for a spin stabilized projectile 16 having an electronic fuzing system 18 which produces an electrical arming signal after the projectile 16 is fired. The cylindrical S&A housing 26 has two faces 28, 30 and a blow through hole 32 through the center of housing 26. A barrier recess 34 is formed in one face 28 of housing 26 and a detonator 40 is mounted on the other face 30 and in alignment with the blow through hole 32. A barrier 36 is pivotally mounted in the barrier recess 34. Barrier 36 is held in its safe position blocking blow through hole 32 by a set back tab 54 and a barrier latch 48. The set back tab 54 is rendered inoperative when projectile 16 is fired from a gun. Latch 48 is bent out of contact with the barrier 36 by a pyrotechnic actuator 56 being activated by the arming signal. When latch 48 is disengaged from the barrier 36, barrier 36 is free to move to its armed position, in which barrier 36 no longer blocks blow through hole 32. Barrier 36 is moved by centrifugal force as a result of the projectile spinning about its spin axis.
