We are now waiting delivery of the further coils which were promised for the first of this month. It is possible that they will come in by parcel post this morning. We have received the cushion springs and tested them with the 50 thou. projection; they definitely hold the pump up. Running dry on half voltage the armature will move forward until it comes into contact with the spring and then stop, the points remaining in contact. On the full voltage the pump continues running but is not particularly quiet. We are experimenting further with a smaller projection, but it does not appear that this is very promising, as in any case the spring is not doing what is intended in the way of silencing the pump. We have not yet received the impact washers from Messrs. Cooper's Mechanical Joints.
