| (COPY) Thermostat Indicator. No doubt you are aware of the Boiling Indicator case that Mr. Breedon is having brought against him. As I understand the position, the Boyce Indicator people are bringing an action against Mr. Breedon for infringing their patent. The Boyce people claim that any instrument the sensitive end of which does not touch the water is an infringement. I understand that Mr. Breedon has already been to the Works and interviewed various of our officials with a view to getting evidence that such a device as this was used long before the registration of the Boyce patent and that you at Derby, in our early days, used a similar device, namely, an ordinary chemists thermometer put through a cork and fixed into the radiator cap, to test the heat of the radiator. Mr. Breedon has now called and says that his case is coming up for hearing on either the 9th. or 10th of next month and he asks that we should allow, Mr. Platford, Capt. Hallam and Messrs. Trayner, Aneers and Warwick to attend the Court to give evidence as above. Mr. Claremont sees no objection to such evidence being given, from a legal point of view, so far as the Company is concerned; and BJ. has no objection provided we are paid for their time and expenses. Will you please, therefore, let me know if you will arrange for this, and if so, will you give the necessary instructions to the officials concerned. C. | ||
