Title: Improvements in or relating to bolometers
IPC: G01K7/00
Filed: 1951-09-20
Abstract: 698,221. Temperature-variable resistors. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 20, 1951 [Sept. 22, 1950], No. 22083/61. Class 37. [Also in Group XL (b)] An electric resistance bolometer comprises a metal of greater than 99.9 per cent purity in contact with a cooling medium so that its temperature is maintained in such a range that the ratio between the temperature coefficient of resistance and specific resistance is at least ten times greater than at room temperature. The Specification explains that in this range the molecular heat of the pure metal is low while the temperature coefficient of the metal is high thus causing a high change of resistance for a small amount of heating. A pair of bolometer foils may be connected in opposite arms of a bridge to increase sensitivity. Noise voltages may be reduced if the foils in two or four branches of the bridge are placed close to each other in a medium at low temperature. Metals with a high characteristic temperature such as Fe, Ni, W and Al and a medium characteristic temperature such as Pt and Cu may be used. Copper may be coated with a dark oxide radiation absorbing layer, the leads also being of copper to eliminate thermo- E.M.F's. A bolometer according to the invention is shown in Fig. 3. The heatsensitive part N is mounted on a copper block M by means of an insulating lacquer. This block is joined to an inner vessel B mounted below a further vessel A containing liquid air boiling at atmospheric pressure. Liquid air enters chamber B from chamber A through a manually set valve D and the vapour in chamber B is drawn through a cooling coil in vessel A by means of a pump A. An intermediate jacket Y reduces heat radiation reaching vessel B. The space between jackets G and Y and vessel B is exhausted. A container of silica-gel is provided. The heat-sensitive part N receives heat through windows O, which may be of rock salt. The radiation may be concentrated by a lens and chopped by a rotating perforated plate. A magnet or magnetizing coil may be fitted around the heatsensitive part since the resistance may increase in the magnetic field with decreasing temperature. An alternating field produced by the bolometer current may be superimposed in the constant magnetic field forming amplifying feed-back. In a magnetic field, bismuth is mentioned as suitable. An arrangement is described, Fig. 4 (not shown), in which the galvanometer is mounted in the copper block. The field of the instrument may be that of the bolometer.

Filed: 1962-06-07
Abstract: 941,403. Dosimeters. ATOMENERGIKOMMISSIONEN. June 7, 1962, No. 22122/62. Heading G1A. In an arrangement for controlling the radiation dose received by an object moved relative to the radiation source the intensity of the radiation is measured and the output of the measuring device used to control the velocity. The source, or the object, or both, may be moving and the radiation used may be electromagnetic, X or gamma,electrons,protons,or neutrons. It is possible to programme the arrangement so that different articles receive different doses. In the embodiment shown an electron accelerator 1 is positioned to irradiate objects 2 carried along on a conveyer 3. A measuring device 5 determines the intensity of the source radiation and its output is fed through potentiometer 11 to regulator 7 controlling the energization of motor 4 driving the conveyer. The velocity of the conveyer is regulated in direct dependence on source intensity so that the dose given to each object is the same. Variation of the dose, either by a programming device or in setting up, can be effected by adjusting the tapping point on potentiometer 11.

Abstract: 730,172. Feeding device for grinding- machines. JONES & SHIPMAN, Ltd., A. A., and HOULDSWORTH, J. Sept. 6, 1951 [Sept. 8, 1950], No. 22179/50. Class 60. After the relative feed of tool and work has ceased in a machine tool, the tool is maintained in contact with the work until the residual strains set up between them in the cutting operation have fallen to a measured and preselected level. In one application, this is accomplished by inserting a strain gauge 8 between a thrust bearing 9 on a feed screw 3 and a post 5 on the machine frame. The gauge, which may be made of one or more materials which show a change of electrical resistance when subjected to pressure or as a condenser with relatively movable plates to produce a change in capacity, is connected to a dial or to a switch controlling an electric circuit for reversing the movement of the grinding head when the pre-selected level of strain has been reached. This circuit may also be coupled to a fixed time delay circuit set to a period greater than that normally required to reduce the strain to the pre-selected level so that, if after the expiry of the normal period, this level has not been reached a lamp or bell is actuated or the machine stopped to avoid damage due to an abnormal condition such as a dulled tool or increased work resistance. The gauge may also be used to give an indication of abnormal conditions at the commencement of an operation. The machine slide 1 is preferably mounted on anti-friction bearings as described in Specification 701,924, [Group XXXIV]. Specification 689,049 also is referred to.
