Patent ES-357835-A1 (ES)
Title: Drum filter of molded construction
IPC: B01D33/00
Filed: 1968-09-04
Abstract: The rotor of a drum filter (which may be of the travelling endless band type, Fig. 1, not shown) has its cylindrical surface formed of impervious moulded arcuate segments 36 which are imperforate and provide a drainage deck. As described, the surface of the segments is formed with axial ribs 42 which support the filter cloth and whose grooves 41 constitute the drainage deck. Ribs 42 are not radial but are instead normal to the segment chord, to facilitate moulding in plastics. Adjacent segments are bolted together at holes 39. Filtrate drains along grooves 41 and enters an arcuate channel 49 in the head plate 47. (There is one channel 49 per segment 36). From there it travels radially inwardly along conduits constituted by matching grooves 54 in facing discs 47, 48, which together constitute one head plate. (The other head 33 is plain). Filtrate thus emerges through a corresponding trunnion duct 53. Fig. 1 (not shown) discloses a manually adjustable tensioning roller (68) for the endless filter band.

Title: Wheel slip detection device particularly for multiwheel vehicles
IPC: B60T8/172
Filed: 1970-04-17
Abstract: To detect transition from rolling to slipping of a wheel over a surface, a transducer coupled to the wheel provides output pulses having a repetition rate representative of wheel speed. The pulses are applied to a logic circuit, including a pair of multivibrators, one of which has a variable time circuit, controlling its unstable state in dependence on pulse repetition rate. Control of the unstable state is obtained by means of a band-pass filter coupled to an integrator, the output of the band-pass filter further controlling a comparison and coincidence network, the output from the network activating a wheel slip detector and, if desired, overriding control of braking.

Title: Method and apparatus for continuously casting metals
IPC: B22D11/053
Filed: 1974-03-21
Abstract: Continuous casting of metal in which molten metal contacts a cooled axial mold wall surface to form a skin increasing in thickness in a direction toward a discharge opening of the mold. At least a portion of the last-mentioned mold surface increases in cross-sectional size over its length in the direction of the discharge opening. The casting is relatively withdrawn from the mold at an average casting rate during the casting operation and also the casting and the mold are oscillated relatively to one another in a particular manner. The maximum velocity capability of oscillation is greater than the casting rate. During oscillation and relative movement of the mold in the casting direction, a substantially constant, compressive loading of the last-mentioned mold surface portion on the skin of the casting is maintained throughout a portion of the last-mentioned movement. Concurrently with the relative movement of the mold in the casting direction, the resistance of the casting to mold movement is allowed to slow the mold velocity to approximately that of the casting, so as to minimize hot tearing of the skin of the casting.

Patent ES-460496-A1 (ES)
Title: Damper control device
IPC: F15B21/08
Filed: 1977-07-07
Abstract: The mechanism features a lined aperture, a flap valve moveable through a controlled distance between the open and closed positions of the aperture, a motor device to move the valve and a control arrangement for the motor. This controller is contained within the motor and is itself actuated by two control circuits. The circuit comprise delicate switching mechanisms connected in series to electrical circuits in parallel to each other and to the flap valve. When the flap valve moves through a predetermined distance it actuates a circuit to move the valve to its second position. The speed of the switching operation is controlled by a times connected to the valve. The valve controls surging of fluid under pressure and is, therefore, partic. useful in systems employing filter bags. It prevents surging when the fluid circulation is stopped or retarded when the operating conditions are changed. It produces a more controlled and swifter flow than standard ball or butterfly valves and is simpler than the device described in U.S. 3898999. Its simple, strong mechanism makes it inexpensive and easy to operate and maintain.
