Title: Method and apparatus for measuring temperature difference of metal surfaces
IPC: G01K3/14
Filed: 1972-11-22
Abstract: 1360940 Measuring temperature differences NIPPON KOKAN KK 22 Nov 1972 [29 Nov 1971] 54036/72 Heading G4H Apparatus and method for measuring the temperature difference between two spaced points on the surface of a steel sheet comprises two detecting coils 1, 2 adjacent the surface 8 at the desired points, each coil being coupled to, and operative to control the output frequency of a respective oscillator 3, 4 such that their output frequencies f 1 , f 2  represent the temperatures at the two points, the outputs of the oscillators being taken to a counting circuit 5 where a digital indication of either (1 -f 1 /f 2 ) or (f 1 -f 2 ) is given, which digital signal is converted in D/A converter 6 and passed to a circuit 7 where the analogue signal is multiplied by constant k in the event that the first expression above is derived, or by 1/a where a is the temperature coefficient of frequency of the sheet. It is shown that for different types of iron or steel sheet, the temperature coefficients of electric conductivity and magnetic permeability are substantially the same and hence no modification of the numbers k or a is required for different grades and qualities of the metal. If the temperature at one of the points is known, the absolute temperature at the other may be derived.

Abstract: 1,259,958. Dividing glass sheets. PILKINGTON BROS Ltd. 29 Oct., 1969 [14 Nov., 1968], No. 54140/68. Heading C1M. Apparatus for dividing glass sheets along a score line 13 comprises an elongated member such as a roller 16 which in use makes line contact with the undersurface of the glass sheet beneath or nearly beneath the scoreline, actuating means which are operable to raise one end of the elongated member, and pressure means operable to apply a bending moment across the raised end of the score line so as to effect a break which runs along the score line. The roller 16 is mounted at one end on a horizontal pivot and at the other end to the actuating means which comprises a double acting hydraulic jack 24. Also mounted on the jack 24 is the pressure means comprising two fingers 29 mounted by means of pivots 30 to a bifurcated member 31 which is in turn mounted on an arm 33 by a pivot 32 at rightangles to the pivots 30. The arm 33 is capable of being moved downwardly by means of a second jack 38. In use the scored glass sheet is fed into a position above roller 16, the roller is inclined to the horizontal, the pressure means being raised therewith, and then the jack 38 is operated to thrust the fingers downwardly so that the fingers engage the glass on opposite sides of the score line to apply the bending moment. The apparatus can be used to trim two opposite edges off a glass sheet in which case two elongated members and associated pressure means are provided. The apparatus may also be used for dividing a glass sheet into two sheets and then removing the outer edges of the sheets, in which case the original sheet is fed into a position above one elongated member, divided and the two resulting sheets are then moved transversely on rollers away from each other so that their outer edges are above two further elongated members. The score line or lines are each produced by a rotatable scoring disc 11 mounted on a shaft 12.
