Patent ES-471678-A1 (ES)
Title: Valve deactivator for internal combustion engines
IPC: F02B75/02
Filed: 1978-07-13
Abstract: An internal combustion engine control system in which intake and exhaust valve deactivators are controlled in response to both engine throttle position and output speed in order to affect split engine operation. Voltages responsive to both throttle position and engine output speed are compared to generate a variable signal that controls the valve deactivators. Each deactivator includes a rotatable first cylindrical member axially fixed on an elongated engine support and also includes a second cylindrical member defining an enclosed cavity with the first member while positioned on the support between the engine and the first member. A helical spring of each deactivator encircles the cylindrical members thereof and has a first end axially fixed relative to the support and a second end that biases a rocker arm bearing toward the engine. Ports of the support and the first cylindrical member define inlet and exhaust passages to the cavity with the first cylindrical member in first and second rotational positions so as to allow the supply and exhaustion of pumped engine oil to the cavity in order to position the second cylindrical member and the bearing axially along the support so as to control valve operation. The deactivators associated with the intake and exhaust valves of selected cylinders are sequenced so that the intake valve ceases to operate prior to the cessation of the exhaust valve operation upon deactivation, and the exhaust valve begins to operate prior to the intake valve operation upon subsequent activation of the valves.

The compensation piston has at least one passage controlled by at least one valve sealing the passage to permit the normal operation of the shock absorber during a rapid deformation of the latter as a result of unevennesses of the road. One or more return springs maintain the damping piston at rest in a middle position relative to the cylinder facing a given zone of the latter. Application to vehicle shock absorbers.

Title: A shear plate for a dry-shaver
IPC: B26B19/42
Filed: 1979-09-14
Abstract: An improved shear plate is provided for a dry-shaver having a movable cutting unit which comprises a plurality of cutters (23) and a corresponding plurality of hair-pulling elements (25) each arranged in front of one of the cutters for movement therewith relative to the shear plate. To enhance the pulling action of each hair-pulling element, the wall (32) of each hair-entry aperture of the shear plate, at the part of the boundary of each aperture where the cutters cooperate with the shear plate to cut off the hairs, is formed with a portion (36) which slopes inwardly of the aperture from the inner side (34) of the shear plate towards the outer side (39). The effect of this sloping portion is to augment that component of the reaction force of the hairs on the hair-pulling elements which gives these elements their pulling action, and also to reduce the frictional resistance of the shear plate to the movement of the hairs by the hair- pulling elements.

Title: Metal casting machine
IPC: B22D39/02
Filed: 1980-09-16
Abstract: The machine has a casting ladle mounted rotatably on a movable support member which conveys the ladle between a filling station and at least one casting station. The movable member carries a motorized rotary disc cam cooperating with a cam-follower which controls rotations of the ladle. The cam profile includes a larger sector of increasing radius to cause a pouring rotation of the ladle at the casting station and a smaller sector of decreasing radius to cause a return rotation of the ladle to the upright position after casting. The cam has, between the two sections, a profile portion which is re-entrant towards the axis of rotation of the cam and in which the cam-follower is engageable selectively to cause a sharp rotation of the ladle from the upright position to an inverted position, so as to release the skin or crust of solidified metal from the inside of the ladle when the latter is at a cleaning station. Control means are provided for avoiding engagement of the cam-follower in the re-entrant portion at least when the ladle is in the casting station, and for disengaging the cam-follower from the re-entrant portion after the inversion of the ladle.
