Single crystals of ferric borate (FeBO 2 ) are grown by preparing a flux melt including borate ions and one or both of lead fluoride and lead oxide such that the ratio [Pb]/([Pb]+ [B 2 O 3 ]) lies between 23 and 33 molar per cent and iron such that the ratio [Fe 2 O 3 ]/([Fe 2 O 3 ] + [Pb]) lies between 17À5 and 30 molar per cent, cooling the melt and separating the crystals therefrom. The preferred proportion of lead is between 25 and 33 molar per cent. The lead may be present as equimolar amounts of PbO and PbF 2 , when the ratio [Fe 2 O 3 ]/([Fe 2 O 3 ] + [Pb]) lies between 20 and 25 molar per cent. When the lead is present as PbO or PbF 2  the ratio [Fe 2 O 3 ]/([Fe 2 O 3 ]+[Pb]) may be 25 molar per cent. The flux may include a crystal growth habit modifying additive such as lead pyrophosphate, gallium oxide, and lanthanum oxide. The melt may also include a doping additive, e.g. Ti, V or Cr, which will have an effect on the magnetic properties of the resulting crystal. In a preferred embodiment a preliminary sintering of the flux components is carried out, the flux composition then sealed into a crucible, heated to 1150‹ C. for 24 hrs., rapidly cooled to 900‹ C., cooled at 1‹ C. per hour to 700‹ C., rapidly cooled to room temperature and then the crucible contents are leached out to retrieve the desired crystals.

A shoe-drum brake has an adjustable anchor 49 adapted for engagement by a shoe 12, means 80 normally locking the anchor to prevent adjustment thereof, an adjusting member 61 for adjusting the anchor, means 67 activated by movement of the shoe in the forward direction A for moving the member 61 to an operative position with respect to the anchor, and a lost-motion connection between the shoe and the locking-means 80 taken-up by excessive movement of the shoe in the direction A for releasing the locking means to permit adjustment of the anchor. As shown, the anchor 49 comprises a screw threaded into an opening 48 in the torque plate arm 42 and having a flat head in the form of a star wheel and a flat knurled top surface against which the web 18 of the shoe 12 normally abuts. The top surface is also normally engaged by a roughened surface on the end portion 81 of a spring-loaded slidable locking-member 80 having a stud 88 projecting with play into a slot 84 in the shoe web 18. On excessive movement of the shoe 12 the play will be taken up and the spring 90 compressed to unlock the anchor so as to permit the adjusting member 61 previously moved to the operative position to rotate the anchor.

In a two-stage control valve a double-acting pilot valve member 206, is displaceable in response to an electric signal to vary the flow of fluid through two pilot orifices 120, 122 carried on the main valve spool 88 to create a pressure differential which acts on the end of the spool to move it. The spool 88 is slidable in a liner 36 having a number of internal annular grooves and external passages (not shown), and the pilot orifices 120, 122, which are formed in a nozzle 124 fitted in the spool, are fed together with the end chambers 101, 103 through axial bores from radial bores 112 in the spool. The pilot valve member which has a forked end that opposes the pilot jets is actuated by an electric torque motor 200 and pressure fluid is supplied through passage 38 in the liner to grooves 44, 46, and eventually exhausts through grooves 74, 78 to passage 22, together with the flow from the pilot jets. Further passages connect grooves 56, 58 and grooves 64, 66 and also lead to opposite sides of the power device to be controlled, so that if the pilot valve member is moved anticlockwise pressure is built up in the orifice 120 and reduced in the orifice 122 and a corresponding pressure change takes place in the end chambers 101, 103 to move the valve spool downwards and restore the pressure balance, and pressure fluid is supplied through groove 58 to the power device and returns through groove 66 to groove 78 and then to exhaust through passage 22. The device operates in the opposite sense for a clockwise rotation of the pilot valve.

A ramp voltage generator has a capacitor 45 as load in the cathode circuit of a valve 10 so that when the valve conducts the capacitor is charged linearly by maintaining the P.D. between the control grid 14 and the cathode 12 constant throughout the duration of the ramp voltage 75. A negative step input pulse 69 causes transistor 56 to conduct and increases the voltage at grid 14 so as to cause the valve to conduct heavily. The anode current now charges capacitors 45, 62 and 68 and passes through the base-emitter of the transistor to hold it conducting. As the potential rises at point 74, the potential rises by a corresponding amount at grid 14 of the valve due to the emitter-collector path provided by the transistor so that the load capacitor 45 charging current through the valve is maintained constant. The anode current begins to decrease when the voltage on screen grid 16 has risen, due to coupling capacitor 40, to a value higher than that of the anode voltage. The slope of the ramp voltage can be varied by adjusting the screen grid voltage or by adding load capacitors 48, 50, 52 or 54. In another embodiment (Fig. 2, not shown), the charging current for capacitor 45 is made linear by a Zener diode (88). Specification 1,010,328 is referred to and describes a circuit for generating the negative input pulse 69.
