Abstract: On their bottom section the brake shoes 3, 4, carrying the linings 8, 9, are connected by a part 5 sliding in a support 2. The separating device 12 acts in concert on the one hand with the upper end of the shoe 3 and on the other with an intermediate part 15, articulated on an extension 17 of the shoe 4. When the wheel drum turns in the reverse direction it drives the assembly 3, 5, 4, 15, 12 in the same direction until the shoe 3 engages a fixed stop 23. The intermediate part 15 then pivots anticlockwise increasing the travel of the separator 12 and thereby reducing the clearance of the shoe 4, which cancels the braking. The invention has application to a device for automatic neutralising of the braking during reversing for a towed vehicle having an overrun brake device. <IMAGE>

Abstract: A rotating drum (9) has first and second writing heads (W1 and W2) and first and second reproducing heads (R1 and R2) mounted on its peripheral surfaces. The respective magnetic heads are arranged at predetermined intervals in the circumferential direction of the rotating head (9) to meet predetermined angle conditions. When a writing operation by the first writing head (W1) is completed, a writing operation by the second writing head (W2) followed. Subsequently, the first reproducing head (R1) reproduces the contents written by the first writing head (W1) and then the second reproducing head (R1) reproduces the contents written by the second writing head (W2). Such one cycle of read-after-write operation is performed while the rotating drum rotates n times (n is integer equal to or larger than 2). Thus, timings of the writing and reading operations by the respective heads do not overlap with each other. As a result, generation of crosstalk can be prevented.

Abstract: The present invention provides asynchronous priority select logic for allowing an individual station on a token ring network to hold a token for asynchronous transmission only for a specified maximum time period. The asynchronous priority select logic comprises a token rotation timer for timing token rotations on the ring from arrival to arrival. A token holding timer limits the amount of ring bandwidth used by the station for asynchronous transmission after the token is captured by the station. Select circuitry responsive to the value of the token rotation timer determines if the captured token is still usable for transmission by determining if the token rotation timer value is less than a preselected asynchronous threshold value. The select logic includes means for generating a selected asynchronous threshold value having a first bit length. The selected asynchronous threshold value is then expanded to a second bit length corresponding to the bit length of the token holding timer value. The expanded asynchronous threshold value and the token holding timer value are then compared and an output signal is asserted if the expanded selected asynchronous threshold value is greater than the token holding timer value.

Abstract: In a film cassette (1), a spool core (23) is supported for rotation in an unwinding direction to thrust a leader section (37) of a filmstrip (F) coiled about the spool core through a film passageway (25) to the exterior of the cassette. A pair of flanges (41, 43) are arranged in spaced relation along the spool core (23) to overlie opposite longitudinal edges (53, 55) of the filmstrip (F) to radially confine the filmstrip. The flanges (41, 43) are adapted to permit the longitudinal film edges (51, 53) to force the flanges farther apart to allow the filmstrip (F) to escape the confinement of the flanges to permit the leader section (37) to be thrust outside the cassette (1). According to the invention, the leader section (37) is relieved (53', 55') to permit its forward edge (63) to be thrust clear of a light-trapping means (31) in the film passageway (25) before the longitudinal film edges (53, 55) begin to force the flanges apart, whereby when the spool core (23) is rotated in the unwinding direction any resistance the light-trapping means and the flanges present to film movement is more easily overcome.
