Patent ES-320271-A1 (ES)
Title: Vehicle tire
Inventor: JEAN-MARIE MASSOUBRE
IPC: B60C9/30
Filed: 1965-12-02
Abstract: A pneumatic tyre with radial cord carcass has a crown reinforcement of at least two plies each extending over the whole width of the tread and whose stiffening effect is different on each side of the mid-plane by virtue of a different radial disposition of the plies on the two sides. The plies may both be of parallel metal cords, or one may be of an elastomer reinforced with metallic fragments. In one embodiment (Fig. 5, not shown), the outer ply comprises two half-width portions each parallel to the carcass ply but at different distances therefrom. The reinforcement plies may be embedded in a band of elastomer.

Patent ES-345666-A1 (ES)
Title: Compressor control including pressure equalizer and overpressure means
IPC: F25B41/04
Filed: 1967-10-02
Abstract: A refrigeration system includes a valve 10 which opens to allow refrigerant to flow from the discharge to the suction side of compressor 12 when the pressure difference across the compressor reaches a predetermined high or low value. The valve includes a casing 25 having openings 28, 34 communicating with the suction and discharge sides of compressor 12 respectively, a piston 45 having a port 48 therethrough, a spring 49 urging the piston towards wall 33 of the casing, a valve member 60 for controlling flow through the port, and a spring 65 urging the valve member 60 towards the piston. Member 60 has a stem 63 which extends through an opening 53 in the piston and is of such a length that when valve member 60 engages its seat 50 the end of stem 63 projects beyond the face of the piston. When the compressor is shut down and its inlet and outlet pressures substantially equal, the piston is pressed against wall 33 and valve member 60 opens port 48 because of engagement of stem 63 and wall 33. At start-up the pressure difference slowly increases and piston 45 is moved to the left, eventually engaging valve member 60 to close port 48. The pressure difference then rises rapidly and piston and valve together move to the left. If the pressure difference becomes too high, the piston engages a stop 47 and member 60 continues to move to the left to open port 48. When the compressor is shut down, the pressure difference falls and piston and valve move to the right until at a predetermined pressure stem 63 engages wall 33 and further movement of the piston opens port 48 to equalize the pressures.

Patent ES-421626-A1 (ES)
Title: Resonant sensing device
IPC: G01N19/00
Filed: 1973-12-19
Abstract: The invention refers to a measuring circuit for determining the properties of a workpiece, particularly hardness, using the contact impedance method in which a probe resonating at an ultrasonic frequency provided with a workpiece engaging tip is utilized. The measuring circuit uses digital counters for producing a digital count which is the difference between the free-resonant frequency of the test probe and the resonant frequency of the probe when the probe is in forced contact with the workpiece. A read-only-memory (ROM) converts the difference frequency count to a hardness value, such as Vickers or Rockwell. The disclosed arrangement obviates the need for zeroizing the circuit and, hence, is self-compensating in respect to drift and thermal stability.
