    Abstract: An optical instrument including means for selecting one of several magnifications of an image being viewed, the selective magnification means being positioned in a collimated light path between an objective lens and a viewing lens and without change of conjugate distances therebetween; also an aperture stop located at one conjugate plane of a relay lens, the other conjugate plane being the nodal plane of the objective lens, which serves as a light-attenuating means without interference with the viewing optical system or without affecting the field being measured.

    Abstract: An integrated circuit comprising several transistors on a chip is maintained at a constant temperature by utilizing certain of the transistors as heating elements and other transistors as temperature sensors in a closed loop feedback network. The remaining transistors-not thus utilized for temperature regulation and sensing are available for use in work circuits where sensitivity to ambient temperature variations or selfheating present design problems.

    Abstract: In a full wave rectified control circuit for a D-C motor comprising two banks of silicon controlled rectifiers for forward and reverse operation, there is provided a pulse generation system which applies a firing signal to each of the control SCR''s when the power to the motor is lost. A short circuit is thereby provided for the motor armature through the control circuit and the rotational energy of the motor is rapidly dissipated to effect dynamic braking.
