Patent GB-2167254-A (GB)
Title: Frequency standards
Inventor: HELSBY NIGEL CHARLES
IPC: H03L7/26
Filed: 1985-10-30
Abstract: A local frequency standard suitable for use in a clock to be synchronised with a reference frequency standard (such as the Rugby MSF transmission) includes a precision local resonator 5 the frequency of which can be adjusted. Periodic determination of the phase deviation between the local and reference frequency standards is performed and the values are accumulated over a period of time. The frequency of the local resonator is then adjusted on the basis of both integrated phase deviation and average phase deviation, with the contribution of at least the former depending upon the reduction of the absolute phase deviation. Microcomputer 3 calculates proportional plus integral terms and simulates switching of filter time- constant by reducing the contribution of the integral term when it has been detected that the phase deviation has been within certain limits for a certain length of time. The proportional term is reduced correspondingly to keep damping constant. Corrections may be logged and then extrapolated when the reference fails, and may also be correlated with temperature or time of day. The loop is preferably third-order. <IMAGE>

Title: Actuation arrangement for aiming mines
Inventor: SEPP GUNTHER
IPC: F42C13/02
Filed: 1986-12-17
Abstract: The fuze comprises a laser range finder LEM acting as a trigger for the mine, two IR detectors IR1 and IR2 serving as arming switches and a microprocessor (not shown) for calculating the target's range R, its speed or angular velocity v and its length L. Should these parameters indicate that the target cannot be hit by reason of too great a range, too high a speed or too small a length, the microprocessor blocks the trigger signal from the range finder. For short targets moving quickly at great range, the hit probability can be increased by the provision of a lead sensor. For targets moving at slow speeds at short ranges, hit probability is increased by delaying the trigger signal. <IMAGE>
