Abstract: 297,931. Barr & Stroud, Ltd., Barr, A., and Stroud, W. Aug. 20, 1927. Logarithmic calculators.-To convert a motion into one following a different law, as for example the angle of sight of an aeroplane into the sine or log. sine of the angle, one part of the range of conversion is effected by toothed gearing of variable ratio and the remainder by cam gearing. The toothed gearing comprises two toothed wheels A, B turning about centres 2, 3 and shaped to give a variable ratio. Towards the end of the travel a pin C on one wheel enters the end 7 of a slot D connected to the other, so that when the teeth disengage, the remainder of the conversion is effected by the pin-and-slot connection. At the end of its travel the slot D becomes concentric with the point 2 so that no motion is communicated. Specifications 15294/14, [Class 80 (i), Gearing, Belt &c.], and 194,124 are referred to.
