Abstract: A time division switching circuit with time slot interchange uses an input shift register to convert one-frame binary coded input data of time division multiplex type from an incoming line into a parallel bit output. The parallel bit output undergoes gate control of a gate matrix and its bit array is statically changed to a given bit array. The on/off control of the gate at the cross point of the gate matrix is conducted according to parallel bit outputs of a plurality of control shift registers which stores predetermined contents. The one-frame bit data thus exchanged are supplied to an output shift register. They are transmitted to an outgoing line as binary coded output data of time division multiplex type.

Abstract: An error correcting encoding and decoding system for transmission and reception of digital data is arranged for high error-correcting ability of both burst errors and random errors. In encoding apparatus a digital signal is processed as a plurality of word sequences. The words are interleaved into a different arranging order and are subjected to different relative amounts of delay. Then, first check words are generated to satisfy a parity detection matrix, such as a Reed-Solomon code matrix. After this, the resulting data words and first check words are again interleaved and are provided with respective different amounts of delay. Then, second check words are generated to satisfy a similar matrix. Finally, the first and second check words and the data words are interleaved prior to transmission. In complementary decoding apparatus, the cross-interleaved received signal is de-interleaved in a fashion complementary to the interleaving performed during transmission and the data words are delayed a complementary amount. The received data words are decoded by providing syndromes generated according to the parity detection matrix and burst or random errors are corrected by the check words.

Abstract: A friction clutch wherein a hub carries a first plate which cannot rotate on the hub and a pressure plate which is non-rotatably connected with the first plate, e.g., by a set of axially stressed leaf springs urging the pressure plate axially and away from the first plate. A clutch disc is interposed between the two plates and is biased away from the first plate by a second set of axially stressed leaf springs. The pressure plate is connected with an annulus of axially parallel rivets extending through the first plate and having heads engaging with a ring or washer at the outer side of a prestressed diaphragm spring bearing against the first plate through the medium of an annular seat which is disposed radially outwardly of the rivets so that the diaphragm spring normally maintains the pressure plate in the engaged position by urging it against the clutch disc which, in turn, bears against the first plate. The pressure plate can be moved to the disengaged position to free the clutch disc by a disengaging bearing which is movable axially of the hub by a fluid-operated motor.

Abstract: An attachment means for clamping two preferably rod-shaped sections (1A, 1B) to each other, so that the sections are secured with respect to each other partly against displacement in the longitudinal direction of the sections (1A, 1B), partly in an optional angular position with respect to each other. The attachment means consists of two wedge-shaped clamping members (6A, 6B), which by means of a through screw (4) and a nut (5) are tightened towards each other thereby exerting a wedging influence on two objects (1A, 1B) to be connected with each other. Resulting wedging forces are taken up as a traction force within two, preferably hook-shaped attachment members (3A, 3B), which are supported by the screw (4) and are retainingly engaged with the objects (1A, 1B) to be connected with each other. Rigid, resilient gaskets (7) are arranged between the clamping members (6A, 6B) and on opposite sides of the attachment members (3A, 3B) which overlap each other. When the clamping members are tightened together the resilient gaskets (7) exert a clamping force on the attachment members under the influence of which said attachment members are secured in angular position with respect to each other. The clamping members (6A, 6B) preferably consist of frustoconical solids of revolution made of rigid plastic material.

The system also provides warnings of dangerous flight conditions during non-tactical or common route segments of a flight such as the take-off, landing and cruise segments of a flight. Circuitry responsive to the arming of the weapons of the aircraft enables the tactical warning portion of the system and disables certain functions of the non-tactical portion of the system that may cause false warnings to be generated during tactical maneuvers. <IMAGE>
