Patent ES-447992-A1 (ES)
Title: Diameter measuring system for cylindrical objects
IPC: G01B11/08
Filed: 1976-05-17
Abstract: A system for the rapid and accurate measurement of the diameter of cylindrical objects and the like, such as nuclear reactor fuel pellets. The system essentially operates on the principle that when an infrared emitter and receiver are aligned in diametrically opposed relationship such that the beam from the emitter impinges on the receiver, the output of the receiver is proportional to the amount of energy received by it. Measurement of cylindrical objects such as pellets is accomplished by passing the object to be measured between the emitter and the receiver. The beam initially is arranged so that as the object passes between the two elements, it partially blocks the beam. Those objects having different diameters or a single object of varying diameter will block more or less of the beam, thereby producing a proportional change in the receiver output which can be correlated in terms of the diameter of the object. Suitable provision is made to compensate for temperature variations in the emitter and receiver.

Patent ES-478996-A1 (ES)
Title: Power steering valve and method of making the same
IPC: F16K3/26
Filed: 1979-03-27
Abstract: An improved power steering valve has a sleeve which circumscribes an inner valve member. An end mill or other rotary cutting tool is utilized to form axially extending grooves inside the valve sleeve. When the end mill is forming the grooves inside the valve sleeve, the axis of rotation of the end mill extends at an acute angle relative to the central axis of the valve sleeve. This results in a groove being formed with axially sloping end surfaces. In order to tend to maximize the compactness of the construction of the valve sleeve, fluid passages or holes are drilled along a sloping path from annular grooves on the outside of the valve sleeve to the sloping end surfaces of the axial grooves inside the valve sleeve. In addition, the compact construction of the valve sleeve is further promoted by forming some of the annular grooves with sloping bottom surfaces so that these grooves are relatively deep. This enables the width of these grooves to be reduced without reducing the capacity of these grooves to accommodate fluid flow.

Date May 1, 1980.The invention relates to a method for regulating the phase position of a controlled signal in relation to the phase position of a reference signal in a telecommunication system, and an arrangement for carrying out the method. A reference signal (C2) is delayed in a delay circuit (DL1) and the delayed reference signal (C2) is delayed in a delay circuit (DL1) and the delayed reference signal (D1) is compared with a controlled signal (C1) in a first comparison circuit (FF1) which produces a first comparison signal (Q1) at a high or a low level in dependence on the phase difference between the delayed reference signal (D1) and the controlled signal (C1). The controlled signal (C1) is delayed in a delay circuit (DL2) and the delayed controlled signal (D2) is compared in a second comparison circuit (FF2) with the reference signal (C2). The second comparison circuit (FF2) produces a second comparison signal (Q2) which is at a high or a low level in dependence on the phase difference between the signal (D2) and the reference signal (C2). The outputs from the comparison circuits (FF1,FF2) are connected to a logic circuit (LC). In dependence on the signal combination received at its inputs the logic circuit produces a binary control signal which is used to correct the phase position of the controlled signal (C1) in relation to the phase position of the reference signal (C2).
