Abstract: 1,247,808. Pyrometers. BLOOM ENG. CO. Inc. Nov.24, 1969 [Feb.25, 1969], No.57433/69. Heading G1D. A temperature measuring device e. g. for measuring the temperature of a steel slab 11 passing through a furnace comprises an open ended housing 14 mounted in the furnace roof with one end projecting into the furnace and the other end projecting out of the furnace, a retractable sight tube 20 slidable within the housing 14 from a retracted position as shown to a position wherein a scale breaker 28 on the end of the tube 20 contacts the slab 11, and a radiation pyrometer.26 mounted outside the furnace on the sight tube for taking a temperature through the passageway in the tube 20. Both the housing 14 and sight tube 20 are water cooled and the tube 20 is provided with a lug 24 to which actuating means for the tube is connected. Compressed air or other gas is fed to an inlet 43 and passes down the tube 20 to emerge through jets 41 at the end of the scale breaker 28 whichis screwed on to the end of the tube 20. In use the slab 11 is positioned beneath the tube 20, which is then moved to bring the scale breaker 28 against the slab with such force as to break the scale on the surface of the slab. The tube 20 is then retracted slightly and compressed air from the jets 41 remove the loosened scale, and a measurement of temperature using the pyrometer 26 is taken. Where scale does not need to be removed the sight tube may be guided by co-operating rails and slides outside the furnace and the bottom of the sight tube may be closed by a ceramic plate which, when brought into contact with a steel slab will resume its temperature and enable a reading to be taken using the radiation pyrometer.

[Also in Divisions A1-A3] A method of treating wood to accentuate the colour difference between annual rings and their intermediate layers of wood comprises subjecting the wood surface to a black-colouring flame treatment followed by sand-blasting with an air stream having a content of sand low enough for the sand not to become embedded in the wood. The flame-treatment may be performed by a pair of blowlamps in succession and may be of such an intensity that it causes the wood to burst into flame at its surface. The sandblasting is preferably effected at an air pressure of 5-9 kg./sq. cm., e.g. 7 kg./sq. cm., using grains of a size less than 0À8 mm. e.g. 0À2 to 0À4 mm. The sand blasting is preferably carried out so that it just removes all the intermediate wood coloured by the flame treatment. The wood used is preferably a soft wood such as Swedish pine.

Title: A device for measuring rates of flow
IPC: G01F1/68
Filed: 1978-10-02
Abstract: A device for measuring the rate of flow of a flowing medium comprising two temperature dependent resistors (11, 12) each of which is arranged in one branch of a bridge circuit. The two temperature dependent resistors are arranged at locations of different cross- section in a tube (10) through which the medium flows. Due to the arrangement at locations of different cross-section, a heat absorption results corresponding to the different velocities of flow at the two resistors and a temperature difference between the two temperature dependent resistors thus results. The consequence of this temperature difference is a difference in resistance which leads to unbalance of the bridge. Thus, the unbalance of the bridge characterises the rate of flow of the medium. <IMAGE>

Title: Controlling Volume in Filled Resinous Systems Prior to Hardening
IPC: C08J9/06
Filed: 1978-10-11
Abstract: Shrinkage occurring in filled resinous systems prior to hardening is controlled by incorporating therein blowing agents that normally generate gas by thermal decomposition, and/or activators for such agents or calcium carbide, in the filled resinous system and causing a comparative positive volume change in the system without the application of external heat to the system and without the development of any significant exothermic heat. Thus, chemical blowing agents generate gas in the filled resinous system to effect its volume, with or without the presence of activators, although maximum exotherms recorded are far below the lowest heat decomposition requirements of the conventional blowing agents utilized and no external heat is applied. Certain known activating agents for chemical blowing agents when used alone without the blowing agent have also shown unexpected abilities to affect the volume of filled resinous systems. The additive may be blended with the fillers for the resinous material in varying amounts to achieve a reduction or elimination of shrinkage or to expand the filled system. Epoxy grouts and mortars incorporating various blowing agents with or without activators are exemplary.
