Patent ES-345223-A1 (ES)
Title: Data transmission system
IPC: H04L25/48
Filed: 1967-09-20
Abstract: Each bit of data to be transmitted is encoded as a main pulse followed and preceded by several "echo" pulses of lower amplitude than the main pulse, the encoding being such that no main pulse coincides with any echo pulse. In the system described each input bit of duration T, Fig. 2 (part shown), produces a main pulse A of duration T/2, two echo pulses a1, a11 of opposite polarity to pulse A, and two smaller echoes a3, a13 of the same polarity, the echo pulses being spaced as shown and having a duration T/2. An input bit of opposite state produces the inverse signal. The transmitted signal is the sum of the encoded bits. The encoder, Fig. 3a (not shown), comprises a shift register fed by the input bits and giving a parallel output. The final stage of the register controls a switched potential divider which passes a pulse representing the main pulse to a first gate. The echo pulses appear at the output of a second gate, one input of which is obtained from a potential divider fed by the outputs of switched dividers controlled by other stages of the register. The gates are enabled alternately for a period T which is 90 degrees out of phase with the input bits. Thus the gates respectively pass two main pulses or two echo pulses when enabled. The gates' outputs pass via an OR gate to the transmitter. At the receiver the original data is recovered by sampling the received signal at times 2nT and 2nt + T/2.

Patent ES-352912-A1 (ES)
Title: Fluid pressure operated clutch and gears with interlock
IPC: F16H63/30
Filed: 1968-04-19
Abstract: A vehicle change-speed gear control comprises a shift-lever 10 mounted on a pin 11 in an inverted trunnion 12 and movable along a gate 9 to pivot the trunnion 12 about pins 13, 14 so that cams 21, 22 on the trunnion co-operate with pistons 15, 16 through rollers 19 to open valves 25, 26 to direct compressed air to a gear selector motor (50), Fig. 5 (not shown), the lever 10 being also pivotable about the pin 11 to move across the gate 9 to rock a hollow shaft 35 carrying arms 64 co-operating with pistons (65), Fig. 4 (not shown), to open valves (66) to direct compressed air to a gear shift motor (70), Fig. 6 (not shown), such rocking of the shaft 35 being prevented by pistons (41), (42), Fig. 3 (not shown), co-operating with lugs (38), (39), on the shaft (35) until the compressed air operated main clutch is disengaged, when the pistons are withdrawn. As shown, the control is for an eight forward speed and reverse gear, and a third piston 17 is controlled by a cam 23 to open a valve 27 to direct compressed air to a dual-range cylinder (not further described), to obtain the top four ratios. A fourth spring loaded piston 18 co-operating with cam 24 provides a delay between selection of fourth and fifth gears. A collar 77 or lever 10 must be raised to avoid a baulk on the gate 9 to obtain reverse. A further pair of arms (67), Fig. 4 (not shown), on shaft 35 co-operate with a pair of pistons (68) loaded upwards against the arms by springs and by air pressure communicated through one-way valves (71), (72) in the shift motor (70) from the pistons (66). Rocking of shaft 35, after the clutch is disengaged, is therefore resisted by springs and air pressure until the split piston (73), (74) in the shift motor reaches either of its end positions, i.e. the gear is engaged, when it abuts and opens the respective one-way valve to release the air pressure acting on the respective piston (68) to allow the other piston (68) to hold the lever 10 in its engaged position.

Title: Pile axle
IPC: G11B17/16
Filed: 1969-02-22
Abstract: A spindle for the turntable of an automatic record change gramophone includes three symmetrically disposed record retaining members 8, which when member 3 is lowered during the change process are urged by spring 9 to a position supporting all except the last record in the stack and three symmetrically disposed record support elements 5 which support and release the lowermost record 12 under the control of member 3 but which, in the absence of records, act to prevent downward movement of member 3, which action leads to switch off of the record player. During upward movement of member 3, after a record change, the elements 5 are moved to their final outer position by engaging with the lowermost record in the stack. In the absence of a record this final movement does not occur and the elements take up a position in which their ends 19 engage with detents 20 formed in the sleeve 1 and thus prevent any downward movement of member 3.
