Abstract: 1,270,144. Automatic steering control. TOKYO KGIKI K. K. Sept. 2, 1969, No. 43418/69. Heading G3R. In a marine automatic pilot a heading indicator is coupled through a clutch to means which control the heading, this clutch being disengaged and another engaged to couple a course-setting means when it is desired to change the set course. In Fig. 2, a gyro-compass repeater (not shown) on a ship drives through gearing 35 a rotary member 8 carrying a compass card 11 so that the heading of the ship is indicated by an index mark on a plate 4 fixed relative to the ship. Member 8 also drives, through a friction clutch 9 closed by a spring 19, a shaft 12 carrying a bar magnet 22 so that an electrical signal dependent on heading is developed by a saturable magnetic device 25 and utilized with a rate feedback component to control the rudder so that a constant heading is maintained automatically. This heading is selected by pressing a knob 31 against a spring 34 to engage a friction clutch 16 and disengage clutch 9 so that magnet 22 may be rotated relative to the repeater compass until a pointer 17 indicates the heading selected. A shield 29 forms an annular viewing area for card 11 through a window 27. A limit switch 21 is operated by rotation of shaft 12 to raise an alarm if the heading error is excessive. A synchro may replace the saturable magnetic device and gears may replace the friction clutches.

Abstract: 1435104 Thyristor circuits MARCONI CO Ltd 27 July 1973 [23 Sept 1972] 44115/72 Heading H3T [Also in Division H2] - A switching circuit comprises at least one thyratron or thyristor 10 ... 12<SP>1</SP> having an inverse diode 14 ... 16<SP>1</SP> and a pulse forming network 18, 18<SP>1</SP> connected to one of its main electrodes and so terminated that the reflected pulse turns off the thyristor 10 ... 12<SP>1</SP>. The circuit is applicable to pulse width modulation, e.g. of a medium wave transmitter. As described, when thyristors 10, 12<SP>1</SP> are turned on the voltage at the right hand side of the load 20 becomes +V and a pulse +V is sent along network 18 and reflected without inversion. The resultant voltage at the right hand side of load 20 is limited by diode 14 approximately to +V and turns off thyristor 10. This results in a pulse of approximately -V being sent along network 18 which on reflection cancels the voltage at the right hand side of the load 20. By triggering thyristors 10 and 10<SP>1</SP> together, the voltage across load 20 is made zero and by varying the relative timing of triggering the pairs 10, 12<SP>1</SP>; 10<SP>1</SP>, 12 the output is pulse-width modulated.

Abstract: 1275931 Lightning arresters GENERAL ELECTRIC CO 9 Sept 1969 [16 Sept 1968] 44428/69 Heading H2H A flip-flop lightning arrester comprises at least two parallel-connected columns each including a magnetic are blow-out coil. The coil in one column is shunted by a spark-gap, and the coil in another column is shunted by a valve resistor. In the construction shown, the parallel columns A, B each include four current-limiting gaps 4 1 , 4 2 , 4 3 , 4 4  and 4<SP>1</SP> 1 , 4<SP>1</SP> 2 , 4<SP>1</SP> 3 , 4<SP>1</SP> 4  in series with blow-out coils 5, 5<SP>1</SP>, respectively. In order to prevent continued parallel operation of the columns when both have sparked over simultaneously, it is arranged that the column B builds up counter voltage much more rapidly than column A and seals off in a few hundred microseconds. This occurs since current increases quickly in the coil 5<SP>1</SP> which has low inductance and resistance. In column A, since the gap 6 is sparked over, the voltage across the coil 5 is very small, and consequently the arcs in the main gaps of the column are only extended slowly. The arrester may have additional parallel columns each constructed in the same way as either column A or column B.

Abstract: 1,192,229. Fuel elements. ALLMANNA SVENSKA ELEKTRISKA A.B. 5 Oct., 1967 [6 Oct., 1966], No. 45457/67. Heading G6C. A fuel assembly comprising a plurality of parallel fuel rods has the rods in the central parts of the assembly a greater distance apart than those in the outer parts. In this way, the neutron flux density within the assembly is equalized so that the heat generated is evenly distributed over the fuel rods in the assembly. In the fuel assembly shown in Fig. 1, the midpoints of the fuel rods 1 in a cross-section of the assembly form the intersection points in a pattern of parallel lines 2 intersecting each other at right angles, the distances between the lines being least at the outer edge of the crosssection. Fuel assemblies in a reactor core are usually surrounded by water columns of different widths at opposite sides of the assemblies and of the same width at adjacent sides. In such cases, it may be suitable to make the rod lattice asymmetrical with more closely positioned rods nearest the wider columns. Such a lattice is obtained by omitting the rods above and to the right of the line A-A in Fig. 1. An alternative embodiment has the mid-points of the fuel rods forming a homologous transformation of a regular pattern, e.g. square or hexagonal, so that the spacing of the rods is uniform around the circumference and less than the spacing in the central part of the fuel assembly.
