Abstract: 1,257,323. Transistor monostable circuit. ELLIOTT BROS (LONDON) Ltd. 6 March, 1970 [7 Dec., 1968], No. 58236/68. Heading H3T. [Also in Division G1] A control circuit for a flash point detector, in which a liquid is heated until its flash point is reached, cooled and then the cycle repeated, comprises a monostable circuit including transistors 24 and 25. During heating of the liquid transistors 24 and 25 are conducting and output buffer amplifier is switched on to actuate a heater. At the same time, transistor 33 is switched on and capacitor 37 is thus charged up through transistor 33. When the flash point of the liquid is reached ignition takes place and a pulse produced in an ionization detector is introduced to the control circuit at I/P to switch off transistors 24 and 25 and hence the heater, the liquid then cooling. Transistor 33 is also switched off and charging of capacitor 37 ceases. Capacitor 26 discharges until the potential at the control electrode of transistor 24 becomes positive with respect to the potential at the control electrode of transistor 38 which is set by capacitor 37, and then transistors 24 and 25 are switched on and the heater again actuated. As transistor 25 begins to conduct a positive transient voltage is applied to monostable circuit 34 causing it to be switched off for approximately one second during which time transistor 36 conducts to partially discharge the capacitor 37. Thus during a long heating period capacitor 37 becomes highly charged and the following cooling period is consequently short since the control electrode of transistor 24 quickly becomes more positive than that of transistor 38. During a short heating period the capacitor 37 becomes less highly charged and is consequently followed by a longer cooling period.

D comprises a store S 1 of a computer C storing the Cartesian co-ordinates of each of spaced points along the simulated coast-line, a store S2 storing sets of elements each set being defined by one of the spaced points and determining the coast-line between that one point and the next, the computer C determines, for each radial stroke of the P.P.I. scan, the set or sets of elements in which at least one element intersects the scan stroke and transforming the co-ordinates of the spaced point defining the or each such set of elements relative to a variable datum, and logic means L determines for each scan stroke the range, from the variable datum, of the point of intersection of the stroke and the nearest one of the elements. In the embodiment a simulated coastline is divided into spans, the points at which adjacent spans meet being termed joints; up to 1000 joint Cartesian co-ordinates may be stored, in computer store S1 and the spans between adjacent joints are each divided into 192 elements of unit length: S2 stores the direction of each element relative to the previous element or joint by two data bits. Store S1 also contains data relating to the ship's actual position aerial height and bearing. The principles for determining which element of a span intersects the P.P.I. range stroke are illustrated in Fig. 4 in which 0 represents ship's position, the joint is at A having Cartesian co-ordinates X, Y relative to 0, and the range stroke is at angle # relative to north: each element of coast-line is drawn in either a N-S or E-W direction as indicated by a two-bit code Fig. 5 (not shown). The computer calculates Y and (Y tan# - X), Figs. 2 and 3 (neither shown), for a span which might intersect the range stroke. The co-ordinates of the point A<SP>1</SP>, corresponding to A, are Ytan# and Y and displacement AA<SP>1</SP> = Ytan# - X is a positive quantity. If the first element AB is north, B has co-ordinates X, Y + 1 and the corresponding point B<SP>1</SP> is such that BB<SP>1</SP> is also positive and hence AB does not cross the range stroke. If the next element BC is east, CB<SP>1</SP> is positive and BC likewise does not cross the range stroke. Element CD is also east but DB<SP>1</SP> is negative thus indicating that CD does cross the range stroke. In case more than one element crosses the range stroke, this procedure is repeated for each element in each possible span, and the logic for effecting the calculations is described Fig. 6 (not shown).
