A series of symbols 36 on each answer plate corresponds to the range of confidence and one such symbol corresponding to each answer is indicated through an aperture 76 in the front fixed plate at a time. The plates are preferably circular, relatively rotatable and the linear elements are arcuate. A number of fixed plates 12, 14, 16 with apertures are interposed between the movable plates. Masking members (80, 82, Fig. 4, not shown) may be used to mark unwanted parts of the front fixed plate when the number of alternative answers is less than the number of movable plates and the rear fixed plate.

In a self-excited alternator having a selfstarting circuit which raises the residual voltage to a preselected nominal level and comprises two diodes L1, L2 connected in parallel between the alternator's line and neutral output terminals the first choke L1 through an impedance network MR1 and the second choke L2 through a first bridge rectifier MR2 whose output is shunted by a first switching means TH1 connected through a second bridge rectifier MR3 to an auxiliary winding 6, 7 on the first choke L1, and output coupling means T1 whose input is connected between the two chokes L1, L2 and whose output is connected to a second switching means TH2 in one arm of a third bridge rectifier MR4 whose output shunts the alternator field winding, residual voltage preselection means ZD1 are interposed between one side of the second bridge rectifier input and the first switching means TH1. As shown, the network MR1 is a bridge rectifier, the two switching means TH1, TH2 are semi-conductor controlled rectifiers, e.g. thyristors, the coupling means T1 is a transformer, and the preselection means ZD1 is a Zener diode. The field winding (12) Fig. 2, is connected to terminals 1, 2 and initially is energized by turning on the thyristor TH2 by e.m.f. from the transformer T1 as a result of a current flow restricted by rectifier TH1 to a path through choke winding parts 3-4 and 9-10. When the alternator line to neutral voltage rises to, e.g. 60V. the choke auxiliary winding voltage breaks-over the Zener diode ZD1 to cause thyristor TH1 to turn on and consequently thyristor TH2 to turn off, at which point control of the bridge MR4 is taken over by a trigger circuit (13).

A shown the first measurement means comprises a magnetic proximity sensor 10, the output of which after being amplified and shaped is fed to a counter 13 which is controlled by a manually settable switch decoder 14 such that the output of the counter 13 is a signal representative of the torque in ft/lb units. This signal is decoded and displayed at 17. In the embodiment shown the wrench body is mounted for rotation and a limit switch 6 is provided, the signal from the switch being fed to a flip-flop 25 and the signal therefrom activates the counter 30 such that the counter begins to count rotation pulse signals. The output of the counter 30 is connected to a comparator 32 into which the aforesaid predetermined total of rotation pulse signals is set by a digital switch 34 and switch decoder 33. The signal indicating that the wrench should be shut off is fed to a buffer 40 and from there to the solenoid valve power supply 50, the wrench being in the form of an air motor 1 controlled by a solenoid operated valve 4. The wrench body may be restrained by a torque transducer which produces the torque pulse signals. Further the shown magnetic proximity sensors may be replaced by photo-electric, Piezo-electric or electric switch devices.

Title: Preparation of polymers
IPC: C07B57/00
Filed: 1973-08-29
Abstract: Products are prepared with a prespecified arrangement of functional groups present therein. In order to prepare polymers having a three-dimensional arrangement of the functional groups, optically active monomers which contain monofunctional or polyfunctional groups and are linked to polymerisable or polycondensable compounds via one, two or more functional groups are polymerised in the presence of a crosslinking agent. When the polymerisation is complete, the optically active compound is separated fully or in part from the polymers at its linking points. The resultant polymers are used for the resolution (separation) of racemates into their optically active compounds.
