Inventor: HAUSER WOLFGANG
IPC: G01K17/00
Filed: 1982-05-10
Abstract: For the purpose of selecting the disposal concept in the disposal of radioactive waste in a disposal mine, and of assessing safety, it is necessary, in particular, to know about the development of heat emanating from the packed final wastes as a consequence of the radio- active decay of the radionuclides. The invention relates to a heat flow calorimeter for measuring the thermal output of a waste drum with radioactive wastes which have a thermal output of up to approx. 300 watts per waste drum by means of establishing a temperature gradient. It is characterised in that the waste drum (1) is surrounded by an absorber jacket (3 to 5) which absorbs the radioactive radiation emanating from the waste drum (1) and is thereby heated, in that at least the cylindrical jacket part (3) of the absorber jacket (3 to 5) is surrounded by a calorimetric block (6), between the inner surface (15) and outer surface (16) of which the temperature gradient is determined, in that the calorimetric block (6) is surrounded by a controllable cooling element (7), and in that the waste drum (1), the absorber jacket (3 to 5), the calorimetric block (6) and the cooling element (7) are accommodated in an outer jacket (9, 13, 17) made of thermally insulating material.

Title: Inert self-curing plastics pads - expanded in situ to support skin grafts and secured by adhesive film to apply uniform pressure on to depressed wound zones
IPC: A61F13/20
Filed: 1982-06-18
Abstract: Poultice comprises a perforated adhesive film (2) which maintains a plug (16) of non-adherent and physiologically inert foam expanded and cured in situ to bear on to the layer of grafted skin (14) covering the wounded zone (10) of flesh. Pref. the cellular plug is of silicone or polyurethane resin, pref. tinted/disinfected/scented to render it sterile and inconspicuous, and incorporating a rapid self-curing system which is not uncomfortably exothermic at ambient temps. Less painful and quicker to apply or remove than conventional bandage covers secured by stitching, the expanded plug also applies more uniform pressure upon the graft, esp. where this enters depressions in the damaged flesh, and permits inspection of the development of the graft. Film and plug are easily disengaged after the skin graft is established.

Title: Method and device for measuring the thickness of a slightly doped layer in a semiconductor slice
Inventor: QUOIRIN JEAN-BAPTISTE
IPC: G01R31/28
Filed: 1984-01-20
Abstract: In order to measure the thickness of a slightly doped layer superimposed on a highly doped layer in a semiconductor slice, there is applied, by the intermediary of a drop of mercury with a contact surface which is well known and calibrated by a probe 18, a variable voltage V between the two faces of the slice; a Schottky contact is thus formed; the slope of the current i variation in the probe in forward bias is measured, which gives the electrical resistance offered by the slice in the direction of its thickness; there is also measured the slope of the variation of the inverse square of the capacitance C of the diode formed between the faces of the slice in reverse bias, which gives an indication of the resistivity of the slightly doped layer. The thickness of the slice is derived from this by a computation using the product of these two slopes.
