Abstract:
PCT No. PCT/EP94/02414 Sec. 371 Date Jan. 29, 1996 Sec. 102(e) Date Jan. 29, 1996 PCT Filed Jul. 21, 1994 PCT Pub. No. WO95/04317 PCT Pub. Date Feb. 9, 1995A temperature derivative sensing and regulating device and method is described which facilitates the maintainance of a very stable isothermal environment for an item, apparatus or facility or a constant rate of temperarture change. The device comprises a block of material having no internal heat sources, a thermal conductivity greater than 100 Wm1K-1 and a specific heat capacity greater than 385 JK-1kg-1. The block is surrounded by means for measuring the heat flow to and from the block and the device is further provided with means for generating a signal proportional to said heat flow and means for interfacing with the controller of a heating or cooling means associated with the item, apparatus or facility.
