Rayleigh Bridge

AP-676

Determining the Self inductance. Design of bridge is simple, even a beginner can understand the connections. The main features are:

1. The Ratio Arm is in 2 dials 1, 10, 100 ohms. each.

2. Rheostat arm is in three dials.

3. Circular slide wire of 0: divided into 170 equal parts connected in series with X.

4. A special Double Key fitted bridge is internally connect! with terminals for Galv. Battery

5. Accuracy ± .05 to .1%

The main feature of the bridge are as under: The ratio arm is in tow dials of 1,10,100 ohms each. The rheostats arm is in three dials having decades of 0.1, 1 & 10. A slide having 0.15 ohms resistance is connected in series with the rheostat arm. The slide wire is calibrated into 100 equal parts for easy calculations. Instead of a simple key a special double key is fitted to bridge. The key is internally connected with terminals for connecting battery and galvanometer. The bridge can also be used as an ordinary Wheatstone bridge. Accuracy ± 0.5 to 1.1% Fitted in teak wood case with lock and key. All the coils are calibrated on Imported Testing Bridge

Research Optical Bench 170cm Lyth

AP-842

It is meant for Research works. Lythe type 170 cms long. A heavy cast iron bed with a strong central rib, thoroughly seasoned and aged before machining and grinding of its upper surfaces. Total length 180 cms; with a machined full length platform for the scale. The scale is from lifetime stainless steel fitted on its machined platform on the bed. Divided in mms to a length of 170cms. Accuracy of calibration + 0.01%.

Riders are provided to carry the standard experimental accessories. Under-surfaces of riders are machined true to fit the machined bed surface, and these machined surfaces are then jointly underground to give perfectly smooth sliding surfaces. Stainless venires fitted to the riders read the scale to .01 cm. The Bi-prism rider is also provided with fine cross motion read by venire to .01 cm.

(i) Optical Slit : With finely ground stainless jaws. Manipulation of jaw movement free from any spring control ensuring maintenance of original accuracy even after prolonged use. The following adjustments are provided for the slit and its carriage.

(a) Linear adjustment along the bed, read by venire to .01 cm.

(b) Fine vertical adjustment by slow motion screw.

(ii) Bi-Prism Holder : Provided with the linear adjustment and fine cross motion by micrometer screw (vernier - .01 cm).Coarse and fine radial motion along the horizontal axis.

(iii) Micrometer Eye Piece : Provided with coarse and fine linear adjustment (vernier = .01 cm).

Micrometer cross motion of the Eyepiece along a 30 - 0 - 30 mm scale read on a micrometer head to .001 cm. Micrometer head fitted with antiback-lash device.

(iv) Llyod's Mirror : Llyod's mirror is provided with special circular scale

Research Spectrometer 10

AP-922E

The cone bearings are of selected materials and the upper and lower parts of the arms are turned and ground in one operation giving the most accurate alignment. Clamps for telescopes and prism table are designed so that no strain comes on the cone-bearings from clamping, thus avoiding any disturbance of the axial alignment. The cone has a carefully determined angle which gives precision centering and at the same time does not give excessive lateral pressure. Scale is 10" from lifetime stainless, divided on the latest dividing machines. Accuracy of calibration within + 0.01%. Adjustment is provided to verniers for very fine opposition to the scale. The slit jaws are from stainless steel, finely ground and the jaw movement is free of any spring action ensuring perfect parallelism at all openings. Vernier Reading 10 sec
