Abstract: 1,250,744. Internally heated hollow roller. DIENES-HONEYWELL HOLDING G.m.b.H. 18 March, 1970 [20 March, 1969], No. 12933/70. Heading B5B. [Also in Division F2] In the embodiment shown in Fig. 1, an internally heated rotatable hollow roller or godet such as may be used for forwarding and heating yarn looped around it and which is provided with a temperature sensor includes a hollow metal roller 1 the hub 2 of which is fixed on to a shaft 3 which is, in turn, rotatably supported by a stationary structure 4 and is coupled to a driving means (not shown). A stationary induction heating coil 5 is mounted inside the roller 1 in a known manner. Alternative heating means, such as electrical resistance heating means, may be used. Fixed to the structure 4 is a flange 6 which, with the cover ring 9 secured about its periphery, constitutes a thermal insulating body preferably made of a poor heat-conducting material such as a ceramics material. The flange 6 near its periphery supports at least one temperature sensor 7, such as a resistance bulb, which is positioned in adjacent radial spaced relation to a portion 8 of the peripheral surface of roller 1. The cover ring 9 is provided with a mirror-like inner surface 12 for reflecting heat radiated from surface portion 8. The cover ring 9 may be integral with the flange 6. The cover ring 9 defines an annular recess 13 with the surface portion 8 and with an annular projection 11 which extends around the peripheral surface of roller 1. The projection 11 distinguishes the surface portion 8 from the greater portion of the peripheral surface of roller 1, and defines one of the four walls of the recess 13 and also defines a clearance 14 with cover ring 9. In a second illustrated embodiment the cover ring 9 is an integral part of a cup-shaped portion of the support structure 4 and extends over the end of the roller 1 facing this structure, whereby the electric connections to the temperature sensor are enclosed and protected. In a third illustrated embodiment of the apparatus of the invention the annular projection 11 of the roller 1 has a greater radial extension than as shown in Fig. 1 and has two axially extended stepped shoulders which overlap a complementary stepped portion at the end face of the cover ring 9 and the outer surface, respectively, of the free end of the cover ring. Entry of the yarn being heated into the recess 13 via the clearance 14, in operation of the roller is thereby prevented.

Abstract: 1,252,899. Controlling oxygen steelmaking. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. Dec.6, 1968 [Dec.11, 1967], No.58035/68. Heading C7D. The velocity, carbon content and temperature of the exhaust gases are determined at a location upstream of that where CO is burnt to CO  2 , all of these factors being obtained by physical measurements only; from them the rate of decarburization is calculated, and refining conditions so controlled that the decarburization rate follows a predetermined course. Preferably the gas velocity is obtained by timing the passage of an acoustic wave through the stream, while carbon content is determined from measurements of the intensity of thermal radiation emitted by the gases in particular wavelength ranges, or from measurements of the absorption of electromagnetic radiation by the gases. The gas temperature may be obtained from the frequency of a stationary acoustic wave set up in a guide of given length positioned in the gas stream. The theoretical bases for the determinations are given.

Abstract: 1288517 Flaw detectors INSTITUT DR FRIEDRICH FÍRSTER PRUFGER€TEBAU 5 Oct 1970 [4 Oct 1969] 47293/70 Heading G1N In an eddy current flaw detecting arrangement, the number of flaws occurring in apredetermined length of product passing a pair of sensing coils connected in series opposition is counted electronically and displayed by a printer. With the coils closely spaced, flaw signals may be indicative of a singly occurring short flaw or variation in depth of a long flaw. To distinguish, flaw signals which occur within a predetermined time interval of the adjacent flaw signal are considered as belonging to a single long flaw and the total length of such a flaw may also be printed. In an alternative, the coils are spaced apart a distance greater than the mean flaw length, which is previously calculated, and such an arrangement can detect the absolute flaw depth, flaw number, flaw length and flaw area (product of length and depth), in the predetermined length and the total length of the product, these values being printed.

Abstract: 1290978 Ultrasonic thickness measuring AUTOMATION INDUSTRIES Inc 2 Sept 1970 42038/70 Heading H4D  A transmitter causes a first transducer to emit ultrasonic energy and a receiver responds to echoes from the first and a second transducer and passes them through a common channel to a measuring means which produces two signals representing the time delay between the transmission pulse and the receipt of energy by said first and second transducers respectively. Pulse generator 44 produces a synchronizing ("sync.") pulse which sets bi-stable 48 and A-D converter 50 to zero and sets bi-stable 40 to close the upper input of gate 38 and the upper output of gate 54. After a delay of 10 ms. converter 50 passes this pulse to main sync. generator 34 which produces two spaced pulses. The first of these pulses changes the state of bi-stable 40 thereby reversing the states of gates 38, 54. Pulser 32 also produces a transmit pulse for transducer 24 which pulse also passes through gate 38 to the receiver where it eventually sets bi-stable 48. Since transducer 26 is isolated by the gate 38, the echo from the top surface of specimen 12 is passed through gate 38 to reset bi-stable 48. The bi-stable output is connected to a ramp generator which thus produces an output whose peak amplitude represents the echo flight time. This is detected by peak detector 56, selected by bi-stable 40 and passed to one input of differential amplifier 58. The second pulse from generator 34 is similarly treated but due to the switching of bi-stable 40, the echo comes from the bottom surface of specimen 12 via transducer 26. Peak detector 60 applies the peak amplitude to the second input of differential amplifier 58 which thus produces an output representing the specimen thickness. Converter 50 produces a pulse whose width is proportional to the amplifier 58 output amplitude and this pulse operates clock 62. The number of output pulses therefrom is counted by counter 64 which is calibrated directly. The pulses are also displayed on a C.R.T. The transducers are mounted in a unit 20 of soundabsorbing material and are displaced from the specimen surface thereby. They are also arranged such that their directional patterns overlap at the specimen bottom surface.
