Title: An automatic tool position compensating system for a numerically controlled machine tool
IPC: G05B19/404
Filed: 1968-11-27
Abstract: 1,211,418. Programmed control of machine tools. IKEGAI TEKKO K.K. Nov.27, 1968 [Nov.27, 1967], No.56353/68. Heading G3N. [Also in Divisions B3 and G1] A numerically controlled machine tool, incorporating a tool selecting arrangement, automatically compensates for deviations of tool position by a measuring element sensing the dimensions of a workpiece on receipt of command information and providing a tool deviation signal for use in automatically correcting the commanded tool feed. As shown, a controller 2 controls movement of a turret C in dependence on command information from a punched tape read by a reader 1. A function device 3 actuates relays, not shown, to index the turret C and select a tool B 1 -B m  in response to signals from the reader 1. Upon completion of indexing a confirmation signal F in  is fed back to device 3 to initiate machining. A measuring element having a feeler 6 is movable in the X and Y directions, through identical steps with the turret C, to engage a workpiece and the X and Y axes position errors are detected by differential transformers within the measuring element casing. The analog error signals are fed to an analogueto-digital converter 7 wherein they are transformed to binary coded decimal values which are fed to the controller 2, wherein they are memorized and used for tool correction of input command position values from the tape reader 1. The tool errors are derived automatically in response to command information read by the tape reader after the passage of a predetermined time. The measuring element comprises a feeler mounted for axial and transverse movement by parallel leaf springs. Axial and movement, transverse of the feeler are detected by differential transformers. The cores of the transformers are each adjusted to give zero transformer output when the dimension of the measured portion of the workpiece is equal to the commanded value.

Title: Improvements in or relating to oxides of metal and metalloids
IPC: C01F7/302
Filed: 1966-12-16
Abstract: Silica when prepared by the process of the invention (see Division C1) is calcined and added to kerosene, and a pink gel is produced. The pink colour disappears on addition of a trace of water.ALSO:<PICT:1121229/C1/1> Oxides of metals of periodic groups 3B, 4A and 4B together with boron, germanium and silicon are prepared by introducing a volatile halide of the element into a flame formed by the combustion of volatile fuel containing a sulphur-carbon bond in oxygen or oxygen-enriched air, the amount of oxygen being in excess of that required for maintenance of a flame, combustion of the fuel and oxidation of the halide.  The fuel preferably does not contain hydrogen and may be carbon disulphide. The volatile halide may be silicon tetrachloride, titanium or germanium tetrachloride, boron or aluminium trichloride or boron tribromide, and in the case of silicon tetrachloride, for each mole of this halide 0.2 to 4.0 moles of carbon disulphide are used. A chemically inert diluent gas, such as nitrogen, may be included in the feed materials.  The product may be calcined to remove volatile by-product.  A suitable apparatus for the above process is illustrated in Fig. 1.  The burner 10 comprises inner and outer feed tubes 14 and 16.  The tube 14 contains at its forward end, an orifice 24 (not marked).  The oxidizing gas enters through 20, and mixes and burns the mixed halide and feed materials producing the flame 38; explosions or blow-backs are prevented by the insertion of the gauze 28 into the tube 14.  The product is collected in the carboy 12.
