Abstract: 1,252,310. Electric arc furnaces. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. 25 Sept., 1969 [17 Oct., 1968], No. 47154/69. Heading F4B. [Also in Divisions H3-H5] In a furnace installation comprising a multiphase arc melting furnace with a plurality of vertical electrodes 2-4, one of which, e.g. 4 dissipates more electrical energy than the others, a conduit 6 joining the arc furnace to a treatment furnace is disposed in that part of the wall which is subjected to greatest radiant heating by the electrode 4 which dissipates the most electrical energy. This arrangement means that the conduit 6 is heated to a higher temperature than the rest of the arc furnace thus preventing solidification of metal therein, and that the refractory lining needs less frequent replacement since the part which normally wears most quickly is taken up by the opening to the conduit. The conduit 6 is lined with a refractory member 11 of high thermal conductivity to improve heat transfer to metal flowing in the channel. Thermal insulation 12, 13 of low thermal conductivity prevents heat flow to the remaining wall of the arc furnace and to the exterior. When the molten metal 9 is covered with slag 7 a fixed or adjustable baffle 8 dips into the metal and conducts radiant heat from electrode 4 to the metal. The electrical unbalance may be deliberately increased by means of a phase regulating device or by modifying transformer outputs to create unbalance between the secondary voltages. The impedance of one phase may be altered by shortening the length of the low voltage circuit for that phase or by using additional choke coils.

Abstract: 1,264,769. Road traffic signals. REMOTE CONTROLS CORP. 2 Oct., 1970 [2 Oct., 1969], No. 47053/70. Heading G4Q. A system for controlling traffic in two phases A, B at an intersection in a sequence determined solely by a recycling timer comprises a clock 30 operating on the 60 Hz mains and supplying a one pulse per second signal at its output 32. Output 32 is connected to a dividing circuit 34 supplying signals sequentially at its terminals 0 ... 9 at 1 sec. intervals. Terminal 9 is connected to a dividing circuit 38 which similarly supplies signals sequentially at its terminals at 10 sec. intervals and likewise a dividing circuit 42 supplies signals at 100 sec. intervals. The ten output lines 36 of dividing circuit 34 are connected, respectively, to the ten positions of a switch 50 and, similarly, the lines are connected to switches 52, 54, 56. In the same way, lines 40 of dividing circuit 38 are connected to switches 58, 60, 62, 64 and lines 44 of dividing circuit 42 are connected to switches 66, 68, 70, 72. The four switch groups are connected, respectively, to AND gates 74, 76, 78, 80. A fifth switch group 51, 53, 55 and AND gate 57 provides a pulse on line 59 to reset the dividing circuits 34, 38, 42. The output of AND gate 74 initiates A phase green; similarly, gate 76 initiates A phase yellow, gate 78 B phase green and gate 80 B phase yellow. Thus, by setting the switches 50 ... 72 at appropriate positions the duration of the red, yellow and green periods of the phases A, B are selected as desired. The outputs of the AND gates are supplied to an encoder 90 and to a memory 89, the encoder being utilized when there is a long transmission path to the traffic lights 20 since it enables the number of wires to be reduced; if the path is short the memory 89 is used. The memory outputs 91, 93, 95, 97 are connected directly to a function steering logic 170 whereas the encoder outputs 92, 94, 96, 98 are connected to a decoder 160 having outputs 162, 164, 166, 168 connected to the logic 170. The logic outputs operate the lights 20 through switches 172, 174, 176, 178, 180, 182 each of which includes a relay and triac. The encoder circuit 90 is described with reference to Fig. 4 (not shown) and the decoder 160 and logic 170 with reference to Fig. 6 (not shown).

Abstract: 1288165 Generating waveforms WAYNE KERR CO Ltd 19 April 1971 [19 Feb 1970] Heading H3T [Also in Division H2] A waveform synthesizer consists of a plurality of differential amplifiers 21, 31 and 22, 32, &c. each dividing a constant current (from 61, 62, &c.) according to the difference between their first and second inputs, all the first inputs receiving a single common signal A and all the second inputs receiving a common reference (earth), and all the current outputs being summed to give the output waveform C. The summing is effected by a common collector resistor 38 for one transistor of each pair 31, 32, &c., and the other collectors are connected in common to the supply 39. Pairs of equal resistors 41, 51, 42, 52 &c., connecting the emitters of a given pair to its constant current transistor 61 62 have different values in the different pairs ; this results in a sawtooth input A producing different sloped outputs for different periods in the different pairs (b, c, d, Fig. 1, not shown) which are summed (a) to give the desired shape of output waveform. The bias to the constant current transistors may be varied at 80 to vary the output waveform C, for example in amplitude or by giving it two inflexions. For input signals exceeding 1 Mc./s., a further in phase sawtooth may be applied through C83 to improve the output waveform. The synthesizer may be used to linearize the output of a non- linear transducer such as a thermistor.

Abstract: 1288289 Discharging laundry articles from an endless conveyer and transfer to other conveyers VSESOJUZNY PROEKTNO-KONSTRUKTORSKY INSTITUT SVAROCHNOGO PROIZVODSTVA 5 Dec 1969 59581/69 Addition to 1274331 Heading B8A A single article of washing is deposited in each carrier 3 of an endless conveyer. The article is scanned by a T.V. camera 13, the scanning movement of which is brought about by engagement of a part of the carrier 3 with a follower on the end of an arm 5. In response to the picture received on the T.V. screen 14, an operator of keying control unit 9 causes a lever 46 appropriate to the desired discharge station, to be raised. The latter brings about the deflection of the carrier so as to tip the article on to a selected delivery platform 4. The level of washing on each platform is sensed by a feeler 32 as described in the parent Specification. At a given stage of filling of the bunkers, conveyer 7 is operated so that carriers 8 are brought into registration with carriers 2 of shelves 3. The carriers 8 are moved parallel with the carriers 2 by the action of a motor 30 (Fig. 1, not shown) and they are moved laterally on rails 16. They are guided by members 25 engaging guides (27), (28), (Fig. 3, not shown), on the carriers 8. Exact registration is provided by members (29). A signal is then generated and transmitted to a series of solenoids 43. These rotate cams 40 each of which operates on a cam-shaft 42 and thereby displaces a push rod 41 into the path of movement of a lever 36 of the mechanism which lowers the platforms 4 in response to the height of the laundry articles as described in the parent Application. This has the effect of simulating a high stack of articles on all of the platforms 4 and in consequence all of the latter are lowered to their maximum extent. Lateral movement of the conveyer 7 then effects discharge of the articles on the platforms 4, on to the carriers 8.

As shown the coils 12, 13 are fed from secondary windings 36, 37 of a transformer 35 fed by a generator 31, and the mid points are connected by a transformer 39. The output from winding 40 is compared in a phase sensitive  demodulator 41 with the output of a phase shifting circuit 42, 43, 44. The output of demodulator 41  may be calibrated to represent either the distance of a conductive body or the conductivity (or material) of a body at a fixed distance. The coils 12 and 13 are essentially similar and their arrangement is such as substantially to compensate for temperature and other extraneous variations. The narrow slit 18 minimizes the effect of re-radiated flux. The flux limiting effect of the membrane 15 is produced by heat treatment, a 5mil membrane being heated for 10-20 minutes at 1430‹F followed by slow cooling. The sensing device may be used in an automatic weighing arrangement comprising an endless belt conveyer supported at one station by rollers 55 supported on a member 58 which is mounted between rubber springs 59, 60. The member 58 carries aluminium discs 65 which are mounted adjacent sensing devices 10, the outputs of these devices being displayed on a suitably calibrated meter 70. The downward travel of the conveyer is limited to protect the devices 10. The sensing device may be used for determining the thickness of paint or oxides, conductivity changes in materials due to variations in temperature, humidity and pressure, and for flaw detection .
