Filed: 1975-12-11
Abstract: 1521499 Direct reduction of ores STORA KOPPARBERGS BERGSLAGS AB 11 Dec 1975 [12 Dec 1974] 50795/75 Heading C7D In the reduction of finely-divided metallic oxide material (e.g. Fe or Ni oxides) with carbonaceous material in a reactor supplied with a gas containing 02 (e.g. air), at least part the off-gas mixture containing CO, CO 2 , H 2 , H 2 O is treated with water (preferably as super-heated steam) to react with CO to form CO 2  and H 2 , whereupon the CO 2  is removed and the gas recycled to the reactor for reduction purposes. The oxide may be iron ore concentrate or calcined pyrites, and the carbonaceous material coke, coal, or anthracite, at least part of which may be replaced by oil. The reactor is preferably a fluidized bed, but may be a rotary furnace. In reaction chamber 1, solids are charged at 6, air at 7, and fluidizing gas at 8, and the metallized product is removed at 11. Gas is separated from the particles in cyclones 2, 3 and exits through pipes 9, 10. The gas in pipe 9 is returned directly to the reactor. Gas from pipe 10 is treated with steam at 12 and iron oxide and/or carbonaceous material and/or Fe-containing material at 13 and passed to cyclone 16 where the solids pass to the reactor 1 and the gas to heat exchanger 19, the gas flow 18 then passing to C02 scrubber 20 (using K 2 CO 3 ) and cooler 27 (for H 2 O removal) prior to returning through exchanger 19 and combining with flow 9 to form the fluidizing gas 8. In another embodiment, Fig. 2 (not shown) there is only one cyclone 2 and one gas conduit 9, the offgas being divided into a portion (33) which is returned directly to the reactor and the remainder (34) passes to a bed (36) of catalyst material (e.g. Cr-Fe) where the H 2 O/CO reaction occurs with steam, the gas flow (37) then treated as flow 18. Typically, 30-70% of the off-gas may be so treated. If desired, all of the off-gas may be treated by combining conduits 9 and 10 in Fig. 1 or by removing conduit (33) in (Fig. 2). The carbonaceous material may be coke breeze, coal breeze or anthracite breeze.

Title: Electronic timepiece
IPC: G04C3/14
Filed: 1974-11-28
Abstract: 1481530 Electronic timepieces CITIZEN WATCH CO Ltd 28 Nov 1974 [26 Feb 1974] 51649/74 Heading G3T An electronic timepiece has arrangements for indicating the pending termination of battery life, although it is stated that alternatively the arrangements may indicate abnormal temperature or humidity within the timepiece or leakage of battery electrolyte. The indication may be the flashing of one of the time display digits in an electro-optical display, or the repeated alternate rapid movement and arrest of the display seconds hand driven by a stepping motor. In Fig. 2, from signals P 1  supplied by a crystal or tuning fork controlled oscillator a frequency divider 2 produces signal P 2  (Fig. 3) at 1Hz. Under normal operating conditions with the battery voltage above a predetermined value this signal is passed by a logic switching arrangement 5 to a display actuator 3, e.g. a step motor. A modulator 7 also receives P 2  and by means of a frequency divider 7f 1  produces a signal A at ¢ Hz. The signals A and P 2  are added in an AND. gate 7a to form a signal B at ¢ Hz. A signal Pc at 4 Hz is derived from a stage in divider counter 2 and is applied to an auxiliary signal generator 8 to produce signal P 8  at 4 Hz which is added to B in an AND gate 7b to produce a twin pulse 4 Hz signal P 7 at intervals of 2 seconds as shown Fig. 3. P 7  is applied to an AND gate 5b. A battery voltage detector 6 produces a low level and a high level signal P 6  when the battery voltage is above and below 1.3V respectively. Thus, normally, with P 6  at low level a gate 5b is blocked and an inverter converts P 6  to a high level before application to the AND gate 5a. Thereby gate 5a is opened to pass the 1Hz signal P 2  to an OR gate 5S and thence to drive the display second hand in 1 second steps. When P 6  is high, battery voltage low, the gate 5a is blocked and gate 5b is open to pass the twin pulse signal P 7  to OR gate 5S and thence to the display actuator 3. This causes the seconds hand to be repeatedly advanced quickly over a display portion corresponding to 2 seconds and then held stationary for 2 seconds, so giving a visual warning of a dud battery. In a modification Fig. 4 (not shown), if no action is taken within twelve days, trains of four pulses occurring at 4 second intervals are produced to drive the second hand, indicating that the voltage is so low the timepiece will soon stop. In the case of an electro-optical display the minutes may be caused to flash intermittently, controlled by signal P 7 , P 5 , and both the hours and minutes caused to flash when the remaining battery life is about twelve days. A.M., P.M. may be displayed.

The 1-outof-10 indications are used to indicate, for each digit, whether or not it is less than 5, and these indications together with a decoded version of the seventh input digit are combined logically to select, for each of the 6 decimal digits, either the 1-out-of-5 or the 2-out-of-5 representation. The selected representations are serialized &c. as mentioned above, to give a series of 6 tones, one per decimal digit, each tone being one of 16 frequencies, a particular one of these frequencies being used if the digit has the same value as the previous digit. The serializer is inhibited and an alarm tone emitted if the input is an invalid combination. The series of tones is used for paging a radiotelephone system subscriber.
