Patent ES-481796-A1 (ES)
Title: Device for synchronizing the carrier and rotatable printing disk positions in an on-the-fly printer.
IPC: B41J1/24
Filed: 1979-06-22
Abstract: A rotatable print disk is mounted on a carrier which traverses along the print line. The disk is moved from each character position to the next by the shortest distance at a constant velocity thus, the time for the disk to move from a given character position to the next will be variable dependent on this distance. The carrier is moved from one print position to the next, a fixed distance, at a variable speed selected in order that carrier reach the next print position in synchronization with the disk reaching the next character position. Upon such synchronization, a print hammer is fired to print the character while the carriage continues on-the-fly towards the next print position. The apparatus includes means responsive to a synchronization failure for reversing the movement of the carrier towards the previous printing position while permitting the continued movement of the print disk to the next character position, and means for then reinitiating the forward movement of the carrier towards the next print position while retaining the print disk at said next character position until the arrival of the reinitiated carrier at the next print position.

Title: Rotating magnetic brush device.
IPC: H02K21/14
Filed: 1981-12-22
Abstract: An apparatus for constituting a rotary magnetic brush comprises a hollow cylindrical member (11) with permanent magnetic strips arranged axially along its periphery. The strips have outwardly directed magnetic poles in a configuration in which north poles and south poles alternate circumferentially. A tube (13) made of non-magnetic substance surrounds said member without touching it. The tube is intended to have particles of magnetic powder deposited on its surface and the particles are made to rotate by rotating the member (4). This causes a rotating layer or "brush" of magnetic particles to be formed on said tube. Said member (11) and the tube (13) which surrounds it are longer than the "brush": An end portion projects beyond the "brush" and is housed in an electrical stator (14) which drives the member (11) by making use of the poles which form the brush. The invention applies to developing electrostatic latent images.

Title: Rock trap for a combine.
IPC: A01D41/12
Filed: 1983-10-17
Abstract: In an axial flow rotary separator, a transition zone between the infeed section and threshing sections is modified to serve as a stone trap or arresting and ejecting device. Radially aligned inner and outer stone collars carried by the separator rotor and casing respectively, obtrude into the annular space between rotor and casing to define between them an annular slot or gate, decreasing or limiting the annular space so as to arrest the downstream passage of stones greater than a predetermined size. The inside surface of the casing immediately upstream of the stone collars is smooth and free of guide vanes to provide a track over which arrested stones may be propelled by conveyor flights of the rotor. A permanently open outlet in the stone track allows the rotor to eject stones tangentially and centrifugally into a stone sump connected to the casing. The stone sump is easily emptied by opening a door accessible from outside the combine body wall.
