Abstract: 671,884. Grinding diamonds &c. INDUSTRIAL DISTRIBUTORS (SALES), Ltd. Aug. 11,1950, No. 20022/50. Class 60. A method of producing faces on diamonds or other crystalline substances consists in mounting the diamond in a dop carried by a tang which is adjusted approximately to orientate the face to be ground, transferring the dop and diamond to an X-ray goniometer to correct the orientation by adjustment of the dop and restoring the dop to its original position in the tang for the polishing procedure. The tang is adjusted to bring the axis of the dop unit perpendicular to the scaife by adjustment of the position of a stem 13 in a clamp at the end of the beam of the tang and by adjustment of two screw-threaded feet 3 with respect to a cross member 8. The. feet 3 have ball ends secured in slidable shoes 5 by split rings. A circular spirit level 16 facilitates adjustment' of the position of the tang. The diamond, or other crystalline substance, is mounted on. a solder dop which is secured to a dop carrier 21 secured by a cotter 26 to a pin 20. This pin is mounted for angular adjustment in a, forked member 19 secured to a pin 18 by a cotter; 25. The pin 18 is likewise mounted for angular adjustment in a forked member 17. To show the extent of these angular adjustments, vernier points secured to the pins 18, 20 co-operate with arcuate engraved scales on the forked members 17, 19. The two pins may be replaced either by a universal ball joint or combined in a single member with co-planar axes at right angles. After the tang has been adjusted to position the axis of the dop unit perpendicular to the plane: of the scaife, the dop unit is transferred to an X-ray goniometer and adjusted in accordance with the crystal orientation of the diamond. When the dop unit has been adjusted it is returned to its original position in the tang.

Title: Improvements relating to level indicators, more particularly for blast furnaces
IPC: C21B7/24
Filed: 1930-07-11
Abstract: 358,579. Bins. TRIGGS, W. W., 57, Lincoln's Inn Fields, London. - (Freyn Engineering Co. ; 310, South Michigan Avenue, Chicago, U.S.A.) July 11, 1930, No. 21022. [Class 20 (i).] The level of material in a blast furnace or other receptacle is indicated by means of a weighted test member, which normally rests on the surface of the material and is controlled by a cable adapted to be wound up by an electric motor, the pull of the motor being limited to a value sufficient to keep the cable taut, but insufficient to lift the test member or to prevent it descending with the charge. The amount of cable paid out serves to indicate the level of the charge. The apparatus shown diagrammatically comprises a test rod 3 moving in a vertical sleeve 3a and suspended from a cable 4 connected to a winding drum 6 driven through gearing from an electric motor 7. The drum drives a recording-device 15 through a flexible shaft 12 and worm gearing 13. The test rod is raised before a fresh charge is fed to the furnace, and an arm 16 is arranged to open a normally closed limit switch 17a when the rod reaches its uppermost position. The bell 2 is operated by a movable cylinder 2a, to one end or other of which fluid under pressure is supplied by a four-way valve 2d operated by a reversible electric motor 30m. When the rod is resting on the charge, current is supplied to the motor 7 through a resistance which limits its torque to the desired amount. When it is desired to charge the furnace a complete cycle of operations is initiated by the momentary operation of a press button switch, which closes a maintaining circuit, and at the same time shorts the resistance. This allows the motor to develop its full torque, and the rod is raised until the operation of the limit switch 17a breaks the circuit and automatically applies a brake 10, which holds the rod in its raised position. At the same time, switches close to complete a circuit through the motor 30m, which operates the valve 2d and causes the opening of the bell 2. When the cylinder 2a reaches its uppermost position, limit switches 17c, 17d are operated to break the bellopening circuit, and to energize the motor 30m in the reverse direction. The bell now closes and the operation of the limit switch 17b completes the circuit through the motor 7 and its resistance, thus re-establishing the original conditions.
