Filed: 1973-03-02
Abstract: 1375679 Measuring shaft displacement electrically SIG SCHWEIZERISCHE INDUSTRIE -GES 2 March 1973 [3 March 1972] 10255/73 Headings G1A and GIN [Also in Division G3] A device for turning a shaft through a predetermined angle in each of succesive periods comprises a displacement encoder mounted on the shaft, a counter receiving the encoder pulses and means which operates when the counter reaches a predetermined value to stop the shaft drive and reset the counter so that it can respond to the next encoder pulse. This ensures that over run errors cancel out in subsequent measurements. The shaft may drive a feed screw. Motor 1 is connected to the shaft 4 via an electromagnet clutch/brake unit 3. Rotary encoder 13 is mounted on shaft 4 . and produces output pulses alternately from photodetectors 21 and 22 which alternately set and reset bi-stable circuit 23 and produce an output pulse train at C. These pulses are fed to counter 24 and at a predetermined count relay 9 is engergized to transfer power from clutch 6 to brake 7 and stop the shaft. Encoder construction, Fig. 2 The encoder preferably has a toothed edge with the teeth 15 of different width (b 2 ) to the space (b 1 ). The pulse generators 21 and 22 are spaced by a distance t which is not an integral multiple of b 1  or b 2  or b 1 +b 2 . Alternatively the encoder may comprise a series of holes 33 in the disc or the sensors may be inductive or capacititive.

Abstract: 582,714. High - frequency discharge apparatus. BROADWAY. L. F., BARFORD, N. C., and PEARCE, A. F. June 25, 1943, No. 10352. [Class 39 (i)] A pair of hollow electrical resonators 4 and 5 are coupled together for the interchange of electrical wave energy by the provision of a wave guide 11 communicating with apertures 12 and 13 provided in the resonators. An apertured diaphragm operating, if desired, like an iris shutter may be provided between the ends of the wave guide for controlling the degree of coupling. The dimensions of the wave guide may be such that its cut-off frequency is just below the operating frequency of the resonator. The apertures 12 and 13 may be made smaller than the cross-section of the wave guide to regulate the coupling.

June 24, 1940, No. 10827 [Class 37] Faults in conductors NX, BX are indicated by means of a relay energized by the secondary 5 of a transformer 1, the primary 2 of which is connected across the conductors NX, BX at, respectively, the point 4 and an adjustable tapping 3. The circuit of 5 includes a rectifier 9 and is connected to earth at E over the lead 13 and to the point 4 by lead 31, whereby NX is normally maintained at a D.C. voltage of about seven volts above earth, but when NX is earthed the relay 8 is short circuited and a contact 25 is released and changes from an indicator C to an indicator F. An extension 7 of primary 2, normally of about 120 volts, is connected over a full-wave rectifier 18, switches 23, and condensers 24 to earth E, the arrangement allowing of any desired capacity being connected between the rectifier and earth so as to bring the potential of conductor NX near that of earth. The output of the rectifier is adjusted by a resistance 21 to about 10 volts supplying a relay 22, which normally maintains contacts 26, 32 in the circuit of indicator C, F, in engagement, but when the balancing arrangement breaks down, contact 26 drops and makes the circuit of indicator O. Contacts 26, 25 are duplicated at 39, 38, respectively, for remote indication. Specification 289,538, [Class 38 (v)], is referred to. According to the Provisional Specification, a bridge-rectifier is transformer-connected to the conductors and its output connected through a high resistance to one conductor and, on the other side to earth, an indicator being connected between earth and the conductor-side of the resistance. It refers also to Specification 290,238, [Class 38 (iv)].

Title: Improvements in or relating to the production of black oxide or iron
IPC: C01G49/08
Filed: 1958-04-08
Abstract: Pigmentary ferrosoferric oxide is prepared by heating converter dust, obtained by refining iron with oxygen bearing gases, with solid or gaseous carbonaceous reducing agents or hydrogen containing gases, the converter dust employed having a size predominantly below 5 microns.  The reduction is preferably effected at 500-800 DEG C. and air is preferably excluded.  The product has the same particle size analysis as the original converter dust and any slight agglomeration may be broken up by passage through a pin mill.  The converter dust employed may be the dust removed from the exhaust gases of converters or the sludge obtained in wet separating processes after drying and disintegrating.  Suitable reducing agents, which are preferably employed in stoichiometric excess, are finely ground coal, charcoal, coke or soot, normally employed in amounts of 1-6% by weight of converter dust; fuel oils, mineral oils and fatty oils, waste sulphite liquor and molasses may be similarly employed. Gaseous reducing agents may be hydrogen, carbon monoxide or gas mixtures containing them in which case the converter dust may be entrained in the gases.  As a modification the hot exhaust gases from the iron converter, containing the converter dust in suspension may be subjected directly to partial reduction so that the ferrosoferric oxide formed is subsequently precipitated from the exhaust gases. Once reduction is complete the iron oxide should be quenched to below 300 DEG C. preferably with a liquid such as water.  The converter dust or the ferrosoferric oxide obtained therefrom may be treated with dilute hydrochloric acid to remove impurities.  According to an example converter dust was mixed with 5% of coal dust, crushed and fed to a rotary kiln heated to 650 DEG C.; the material leaving the kiln was cooled to about 100 DEG C. and broken up in a pin mill. Further examples relate to the reduction of converter dust with spindle oil and carbon monoxide respectively.

[Class 37.] The rotatable element of an indicating device is provided with means adapted to co-operate with the light from a fixed source in such a manner as to produce on a fixed scale an optical indication of the movement of the element over 180‹ of the rotation thereof. As shown applied to the controls of a wireless receiver the spindle 2, Figs. 1 and 2, say, of a variable condenser is provided with a spherical segment 1 of polished steel and mounted eccentrically. Light from a fixed source 4 is arranged to fall on the spherical surface and is reflected on to a scale plate 5. The light may be produced by a hair line filament or may be passed through a narrow slit and not focussed. In a - modification shown in Fig. 3, the shaft 2 carries an arm 9 with a pin 8 the shadow of which from a source of light 4 can be projected on a scale 5. Instead of a shadow a line of light can be used to form the indication by means as shown in Fig. 4 wherein the image of a slit 11 in a drum 10 on the spindle 2 is projected on to the scale 5 by the reflection from a mirror 12 cf a beam of light from a source 4. In these arrangements the index moves along a line at right-angles to the spindle the direction of movement may, however, be changed by the use of mirrors.
