An indicator 27 with a rotatable needle 29 represents rudder pedal position and a linear scale instrument 31 represents rudder force. The drive system for each control is essentially the same and in that, 43, Fig. 3, for the rudder, movement of rudder 45 will result in a force output from transducer 47 which is amplified at 49 and force divided by mass is integrated at 51 to obtain velocity which is then integrated in integrator 53 to provide a position signal. The force output is taken from amplifier 49 and both force and position outputs are scaled in a block 55, which may be in the simulator computer or may be a summing amplifier having the required scaling resistors. The force output on line 57 is directed to meter 31 which has a meter movement coil 59 and an adjustment potentiometer 61. The position output is directed to indicator 27 which similarly has meter coil 63 and potentiometer 65. The aileron system block 67 and elevator system block 69 will be identical to rudder block 43 and the meter movements of the indicators 11, 19 and 21 are similar to those of indicators 27 and 31.

Abstract: 227,917. Tilling-Stevens Motors, Ltd., and Whitehorn, H. K.. Oct. 24, 1923. Armatures and field magnets; windings; motors, controlling. - In a dynamo-electric machine having a single armature with separate commutator windings, the windings have equal numbers of turns and are so arranged in the slots as to equalize at any instant the linkage of the magnetic flux with the windings for all positions of the conductors down the depths of the slots. The invention is particularly applicable to double-commutator machines, of which the windings are arranged to be connected in series or in parallel, such as the motors employed on petrol-electric vehicles. The armature 3, Fig. 1, has three coils per slot, the conductors D forming one commutator winding, and the conductors d forming the other. Each main pole 1 has separate field coils A and a corresponding to the two armature windings and the coils on alternate poles are oppositely arranged. A similar arrangement is adopted for the coils B and b on the commutating poles 2. Fig. 2 shows a modified construction of armature winding for one coil per slot, the form shown on the left being effective in the case of a machine having a large number of slots. Other modifications having two and five coils per slot are described in which the conductors of the two windings are alternately arranged.

Abstract: 680,387. Roller mills. COMBUSTION ENGINEERING - SUPERHEATER, Inc. Nov. 2, 1950 [Nov. 17, 1949], No. 26752/50. Class 59 A roller mill, comprising rollers 9 mounted on shafts 10 pivoted at 12 and main spring means 16 urging the rollers towards a grinding track 3, is provided with stop means 23 to limit the movement of each roller towards the grinding member and a relief spring 26 acting in the opposite direction to the main spring means. The springs are mounted between a pair of adjusting bolts 18 secured by nuts 19 to the casing and adjustable yokes 20 and 27 are provided for varying the pressure exerted by the springs. An arm 11 connected to the shaft 10 is forced by the main spring 16 against a third yoke or stop 23 which is adjustable to allow variation of the grinding gap between the roller and the rotating bowl 3 and the relief spring 26 bears on a round rod 24 on the arm 11 by means of a member 29 having a plunger 30 passing through the yoke 23. The spring pressure on the arm is the pressure of the main spring minus that of the relief spring, and is low but increases rapidly as the grinding gap between roller and bowl increases in order to pass more material, until the relief spring goes out of action when the shoulders 31 of the plunger 30 engages adjustable shims on the top of the arm 11. The main spring then acts alone, giving a smaller increase of pressure for a corresponding widening of the gap. The material is fed through a tube 8 and opening 8<SP>1</SP> and is removed by an air current, any insufficiently ground material being separated out by a classifier Q and returned to the opening 8<SP>1</SP>.

Title: Improvements in or relating to voltage measuring circuits
Inventor: JULIE LOEBE
IPC: G01R1/28
Filed: 1968-06-05
Abstract: 1,236,092. Voltage measurement. JULIE RESEARCH LABORATORIES Inc. June 5, 1968 No. 26757/68. Heading G1U. A precision potentiometer circuit 9 incorporates a voltage source 10, a first variable resistance 11, a second variable resistance 12-15 adjusted to a standard value Rs and a voltage divider 16 having an input circuit of constant input impedance R IN ; the voltage source, first and second variable resistances and the divider input circuit being connected in a first series circuit. An adjustable output for comparison with an unknown Ex is derived from the voltage divider. To calibrate the system a standard voltage source 24, which may provide e.g. 1. 01830 volts from three standard isothermally lagged cells is connected in series with a null detecting meter 27 across Rs + R IN , and the variable resister 11 in the series circuit is adjusted until a null is derived. R IN  may be 100 K# and Rs set to 1830 #, so that the voltage across R IN  will then be precisely 1 volt. To reduce the effects of resistance variation on the precision of operation, Rs/R IN  <2%. A switch 26 enables the meter to be subsequently connected with the unknown voltage source Ex to be measured in series opposition with the divider output. The above arrangement enables a calibrated input voltage to be applied to the divider 16. In order to calibrate the dial 20, which indicates the value of the divider output, both the scale factor for the dial 20 relative to the potentiometer system and the divider ratio calibration factor must be determined. The first is ascertained by connecting the reference source 24 in series with the meter 27 across the output circuit of the divider and a standard resistor 21 in the input energizing circuit for the divider, connected to the common input/output terminal 18. Any difference between the actual and expected meter reading represents the scaling error. The divider ratio error is determined by connecting a precision resistor chain across the divider input circuit 17, 18 and comparing the voltages tapped therefrom with supposedly equivalent output voltages obtained across 19, 18 Fig. 1A (not shown). The potentiometer may be used in association with a voltbox, of the type incorporating a resistor chain to which a large input voltage is applied, the voltage tapped across part of the chain being compared with the output of the divider. The errors in the resistor chain of the voltbox may be determined by energizing the box from a known source, so that the output from each tapping point should be of given value and comparing these outputs with outputs of the given values obtained from the divider Fig.3 (not shown). All the above arrangements may be combined in one unit incorporating one null detecting instrument and standard voltage source, appropriate switches being provided to set up the various circuit configurations Fig.4 (not shown).
