Patent ES-8202956-A1 (ES)
Title: Frequency check apparatus and utilisation in Go/No-Go apparatus.
IPC: G01R23/15
Filed: 1981-03-06
Abstract: A frequency check apparatus, for example, for a GO/NO GO control function in a chopper controlled traction motor control system is required to permit operation at only the correct chopper frequency and also normal start up from rest when the chopper frequency is zero. A conventional bandpass filter type frequency sensing channel (2) discriminates between operation at correct and incorrect frequencies but cannot respond in the required manner to zero frequency. To permit zero-frequency detection a signal generator (11) is coupled to a second and appropriately responsive channel (3) via a saturable magnetic circuit (13) which is also coupled to the frequency carrying conductor (4). At any operating frequency the magnetic circuit (13) is saturated and the second channel (3) is blocked so that the control function is provided by the first channel (2). At zero operating frequency the signal generator (11) is not blocked and while the first channel (2) is not energised the control function is provided by the second channel (3). The outputs of the first and second channels are connected via an OR gate (1).

Patent ES-8303007-A1 (ES)
Title: Threshing and separating drum for an axial-flow combine harvester.
IPC: A01F7/06
Filed: 1982-01-28
Abstract: In an axial flow rotary separator for a combine, radially extending spike-tooth-like blades are arranged on a rotor body in "reverse" helical arrays, that is, such that helical flighting, similarly disposed, would tend to convey crop material upstream. The helix angles defined by the arrays approximate that of the mean spiral path of conveyance of a crop material mat portion through the separator housing. Propulsion of the crop material mat thus results from a plurality of spaced and staggered engagements of small contact area. The arrays are spaced so that the rotor elements present no extensive wall or front to the crop material thus reducing the tendency to "roping" and separator plugging in tough straw conditions.
