Patent ES-303585-A1 (ES)
Title: Hoisting chains
IPC: G21C7/14
Filed: 1964-08-29
Abstract: An articulated hoist chain comprises a series of rigid open-ended tubular links 60 pivotally connected in alignment with one another by means of universal-joint connections which permit each link to pivot through a limited angle relatively to the adjacent link about two transverse pivotal axes, there being a continuous internal passage through the chain from end to end. Each link at each end comprises two axially-protruding tapering nose portions 61, those at one end being angularly displaced by 90 degrees with respect to those at the other end. The universal joint comprises a gimbal ring 64 pivotally connected to the end portions 61 by screws 65, 66. In a modification the pivot pins are welded to the links. The chain is used in a hoist of a fuelling machine for servicing vertical channels in the core of a nuclear reactor, flexible service leads, such as electric cables, pneumatic or hydraulic pipes, or flexible mechanical drives extending through the central passage formed by the aligned bores of the tubular links of the chain. Four powerdriven hoists 30, Fig. 2 (not shown), are mounted on a platform 21 at equal angular spacings around a charging tube 15, and the platform 21 can be rotated through successive angular steps of 90 degrees so as to bring each of the hoists 30 in turn into alignment with a telescopic drive shaft mechanism 36.

Title: Improved Pulse Analyzing Apparatus and System
IPC: H03K5/1532
Filed: 1967-02-23
Abstract: In apparatus for determining the pulse amplitude at the centre of the pulse, the pulse is integrated in such manner that the curve of the integrated pulse is equal to that of the input pulse at the time centre of the input pulse, a gate is arranged to be opened when the two curves reach equality at the time centre, said gate passing a signal, equal to the pulse amplitude at the time centre, for a fixed time period. Detecting particles in fluids. The invention is applicable to particle detection systems of the type described in Specification 722, 418, Fig. 1. (not shown) relates to the isopotential lines surrounding an aperture in a sapphire wafer separating two liquid-containing chambers. It is shown that the shape of the current pulse produced between the two liquids when a particle of given size passes through the aperture is a function of the path of the particle relative to the axis of the aperture the peak value of the current pulse only coinciding with its time centre when the pulse travels along the axis. It is shown that the pulse magnitude at its time centre is constant for a given sized particle, irrespective of the path through the aperture, hence when pulses are manipulated by the system described below, a more accurate determination of particle size is obtained. Reference is made to the use of a long aperture followed by a low pass filter or to the rounding of the contours of the aperture so as to provide more uniform current density. Such methods are, however, stated to be less advantageous than the system described below. Determination of pulse amplitude at the time centre. As shown in Fig. 2, pulses 52, Fig. 3, from 40 (derived from the current through an aperture in a wafer separating two conductive liquids) are passed via a gate 68 to an integrator 74 which provides a curve 76, Fig. 3, adjusted to become equal to that of the curve 52 at a time approximately equal to its time centre. A monostable multi-vibrator 114 is triggered by circuits 82,104,108 when the instantaneous values of the integrated pulse 76 and input pulse 52 are equal i.e. at substantially the time centre of the input pulse 52. The output of 114 opens a gate 120 which passes the centre value 124 of the pulse 52 to classification circuits 134 for a short period. Noise is inhibited by a threshold circuit 56, feeding a leading edge detector 140 and bi-stable circuit 66. This arrangement ensures that only pulses the amplitude of which exceeds the threshold of 56 are passed by the electronic switch 68. Circuits 56,66,74 are reset by the trailing edge of the pulse from 114. In Figs. 5, 6 (not shown) the mono-stable multivibrator 114 provides a longer duration pulse which is used to gate the output of the integrator which, in this case, is arranged to remain constant at the value reached at the time centre of the input pulse.

Title: Improvements in and relating to Data Transmission Systems
IPC: H04L25/48
Filed: 1968-08-03
Abstract: The invention provides a digital transmission system in which the potential level of the transmitted signal changes from a first level to a second (or vice versa) at the beginning of each bit and also changes from one level to the other at the centre of each bit of a particular state, see Fig. 3F. An encoder for converting input binary signals, in which the two bit-states are represented by two potential levels, to binary signals of the type defined above is described. A regenerator and receiver, comprising a regenerator followed by a decoder, are also described. At the transmitter, Fig. 1 (not shown), input unipolar binary signals Data I/P, Fig. 3, are gated with square wave clock signals A from an oscillator (see below), the clock signals having a repetition frequency twice the bitrate of the binary signals. The resulting signals D are gated with a bit-rate waveform C, the gate output E controlling a J-K bistable circuit which develops for transmission signals F of the type defined above. At the regenerator, Fig. 4 (not shown), the received signal, Line I/P, Fig. 6, is squared up and passed in true and complement form G, H to a bi-stable circuit whose output J, K passes passes both to a further bi-stable and to a clock circuit (described below), which extracts a clock signal P from the data. The clock signal P controls the further bi-stable whose output Q is the regenerated input data. The receiver comprises a regenerator as described above feeding a decoder, Fig. 7 (not shown). The regenerated signal and its complement R, R, Fig. 9, pass via filters to a buffer bi-stable whose output S, #S feeds monostables generating U, T. These are gated to give V, V being gated with a clock signal CC derived from the clock signal M of the regenerator. The output, Set 0, is applied to one side of a bi-stable. To the other side is applied Set 1 which is derived from V by way of an inverter, giving W, followed by a monostable, giving Y, and a gate fed by both W and Y. The bi-stable output is as DD and EE, identical to the original binary data signal. V and Y are gated to give a bit-rate clock, Strobe. The oscillator, Fig. 2, comprises crystal. X1 and inverters 21, 22. The interverters are formed of transistor-transistor logic integrated circuit NAND gates with the inputs commoned. Inductor L1 causes the inverters 21, 22 to act as class A amplifiers. The clock circuit, Fig. 5, is fed at 501, 502 by J, K,.Fig. 6. The-rectifier output L, L feeds a crystal filter comprising crystal X2 which oscillates at twice the bit-rate. The filter output passes to the transistor shown, whose output is the twice bit-rate clock M. Reference has been directed by the Comptroller to Specification 892,552.

Title: Step tracking system
IPC: G01S3/44
Filed: 1973-10-11
Abstract: This step tracking system is applicable to the angle tracking of any source of energy and includes a pair of stepper motors to mechanically move an antenna, one motor moving the antenna in azimuth and the other motor moving the antenna in elevation. The stepper motors are alternately driven for step scanning by a common source of a pseudo-random step scan waveform having balanced positive and negative excursions. A tracking error control signal is generated from the difference in amplitude of the amplitudes of two adjacent samples of a received waveform. The received waveform is similar to the pseudo-random step scan waveform and one sample is taken in one of adjacent higher and lower intervals of the received waveform while the other sample is taken in the other of the adjacent higher and lower intervals under control of the pseudo-random step scan waveform. A second order servo control system is provided for each of the stepper motors. The servo control system associated with the scanning stepper motor is coupled to respond to the tracking error control signal to cause the scanning stepper motor to take a tracking step to reduce a detected tracking error in the associated one of the aximuthal and elevational motion. A backup programmed tracking control circuit is provided for coupling to the servo control systems to cause the antenna to track the source of energy in place of the tracking error control signal.
