Title: Nuclear reactor fuel elements
IPC: G09F3/00
Filed: 1974-01-21
Abstract: 1484071 Fuel elements UNITED KING- DOM ATOMIC ENERGY AUTHORITY 13 Jan 1975 [21 Jan 1974] 02753/74 Heading G6C An insert for a nuclear reactor fuel element whereby the fuel element may be individually identified bears an array of markings at spaced positions to produce a series of signals on presentation of the insert to a detector responsive to each marking and further markings at some only of the spaced positions to vary the series of signals produced on presentation of the insert to the detector. The insert can thus provide both clock pulses from the array of markings at spaced positions and numerical identification pulses from the further markings to ensure uncritical time dependence when the insert is passed through a detector. Preferably, the insert (Fig. 1) is a metal bar 10, which may be tubular, and the markings are holes 11 extending through the bar, the further markings being holes 12 of larger diameter and at right angles to the holes 11. As an alternative (Fig. 2, not shown), the markings may be grooves with the further markings provided by deepening certain of the grooves. In Fig. 4, the fuel element 17 containing the insert is shown being drawn through an eddy current reading head 19 in which electrical pulses from an oscillator 21 are modulated in response to the presence of the markings on the insert and those modulated pulses are compared with the pulses from the oscillator 21 in a mixer/amplifier 22 from which high and low level pulses are obtained. These high and low level pulses are fed into a pulse height discriminator 23 in which the high level pulses are distinguished and with the combined high and low level pulses (clock pulses) applied to a logic circuit including decoder equipment which converts the data provided by the high level pulses into decimal form for printing or visual display.

Filed: 1976-01-26
Abstract: 1531827 Glass breakage detectors AMERICAN DISTRICT TELEGRAPH CO 26 Jan 1976 [30 Jan 1975] 2860/76 Heading G4N An alarm system comprises means for establishing an acoustic standing wave pattern in an acoustically propagative medium, e.g. a glass window pane, a receiving transducer affixed to the medium surface for sensing the pattern and producing a signal representative of the amplitude and/or phase of the sensed pattern, a mixer operative in response to the signal from the receiving transducer and from an oscillator which causes generation of the pattern to provide a mixer output signal, processing means operative in response to a change in the mixer output signal for producing an intermediate signal representative of the magnitude of such change, means for establishing a reference threshold representing a non-alarm condition, and means for providing an output signal representative of an alarm condition upon exceedance of the reference threshold by the intermediate signal. As shown in Fig. 1, the output of the transducer 16 is mixed at 30 with the oscillator output, and the mixer output is applied to the circuit shown. The limiter 36 prevents relatively large amplitude signals from charging the integrator 38 at an erroneously fast rate. This system may be modified to use quadrature processing, Fig. 2 (not shown). As shown in Fig. 3, a single transducer 54 is used for transmitting and receiving, a hybrid transformer 58 being provided for applying the received signal output to the mixer 62 whose output may be processed as shown in Fig. 1. Quadrative processing may also be used in this embodiment. A plurality of window panes may be monitored either by applying the outputs of the transducers 16 to a summing network whose output is applied to a mixer, Fig. 4A (not shown), or by applying the outputs of the transducers 54 to a single hybrid transformer, Fig. 4B (not shown). The walls of a display cabinet, a security vault or a filing cabinet may be monitored in the same manner.

In a railway vehicle having two wheel-sets mounted on the vehicle frame 4, each wheel-set is mounted on the body through a suspension comprising multistage vertical springing having different spring rates for different loadings, swing-links 8 having low lateral stiffness, longitudinal traction rods 17 and hydraulic dampers 24, 25 damping vertical, lateral, and roll motions. Each wheel 1 of the wheel-set is mounted on a line axle rotatably mounted in axle boxes 3. In one embodiment (Figs. 2 and 4) the vertical spring comprises, on each side of the vehicle, nests of coil springs 13, 14 supported on base members 12 in turn supported on knife edge members 10 slidably mounted on the swing links 8. The swing links 8 are suspended, by way of knife edge members 6 and rubber pads 7, from a longitudinal beam 5 secured to the axle box 3, the knife edge members 6 supporting T-shaped upper ends 9 of the links 8 to permit longitudinal movement between the wheel-set and the frame 4. The knife edge members 10 are adjustable, longitudinally of the links 8, by way of nuts 15 for equalization of wheel loads. Each spring 13 engages at its upper end a bracket 16 on the frame 4, but each spring 14, which is shorter, does not engage this bracket 16 until the vehicle is part loaded. Each traction rod 17 is attached to an axle box 3 via spherical mounting including a spherical rubber bush (20, Fig. 3, not shown) of low torsional and conical stiffness and high radial stiffness, and extends towards the transverse centre line of the vehicle for attachment to a bracket 19 via a differential rubber spring 23 of low conical stiffness and the required axial stiffness. In a second embodiment (Fig. 7) the vertical spring comprises, on each side of the vehicle, tapered leaf springs 40 and coil springs 48. The leaf springs are mounted on the axle box 3 and support at their free ends knife edge members 6, 7 at right angles to one another. The swing links 8 hang from the knife edge members 6 and slidably support knife edge members 10 supporting base members 12. Each base member 12 supports a rubber unit 46 mounting a plate 47 which supports the coil spring 48. The upper end of the coil spring 48 abuts a platform 49 at the lower end of frame-brackets 50, a spigot 51 depending from the platform 49, so that on partial loading of the vehicle this spigot 51 abuts the plate 47 to render the coil spring 48 ineffective. The traction rods 17 are again attached to the axle boxes via spherical mountings, and the other ends of the rods 17 are attached to a plate 54 connected to the frame via a member 55 and a bracket 50. The plate 54 is sandwiched between a series of rubber dies 53 compressed between end plates 56 secured to the rod 17, the compression of the discs 53 being adjustable by a nut 17.
