Title: Method and a control device for operating a polyphase electric furnace
IPC: G05F1/14
Filed: 1969-05-23
Abstract: A polyphase electric furnace such as a three phase reduction furnace is operated at a constant power input with the electrode currents maintained at equal values, the latter condition being achieved by varying the voltages between the electrodes upon the occurrence of dissymmetries in the charge resistance. In the described embodiment the electrodes 1, 2, 3 are supplied from transformers 7, 8, 9 controlled by members 4, 5, 6 of the control system shown in Fig. 2 which varies the voltage associated with the pair of electrodes having the least difference in current, for example the transformer 7 if the current difference between electrodes 1 and 2 is less than the current difference between electrodes 1 and 3. Members A---E are known controllers which function as follows: - (1) Controller A compares actual power Wa with desired power Wd to determine the output signal from controller B. (2) Controller B receives a signal Id representative of desired electrode current, which signal is varied by the output signal from controller A to produce a corresponding desired current signal I'd. (3) Controllers C 1 C 2 C 3 compare the actual current through each electrode with the desired current signal I'd, the outputs of these controllers each being applied to the pair of the members 4, 5, 6 associated with the corresponding electrode e.g. C 1 supplies members 4, 6 associated with electrode 1. (4) Controllers D 1 D 2 D 3 compare the actual electrode currents to derive corresponding difference signals each of which is supplied to an appropriate pair of the controllers E 1 E 2 E 3 (5) Controllers E 1 E 2 E 3 compare the pairs of current difference signals and control appropriate pairs of the members 4, 5, 6 to determine which of these members is to respond to an adjusting instruction produced by a corresponding controller C 1 C 2 C 3 , this determination being based upon the criterion of least current difference already defined.

Title: Device for severing a travelling yarn thread
IPC: B65H54/71
Filed: 1969-07-10
Abstract: A device for severing a travelling yarn 1 or like elongated material comprising a cutter 17 connected to a piston-rod 18 of a piston 19 which is adapted to be actuated by compressed air under the control of a valve 31, the air being fed, in one position of the latter, to one side of the piston in order to load a spring 16 and in a second position of the valve, to act on the other side of the piston in order to drive the cutter on its operative stroke in addition to the power supplied by the loaded spring. The yarn 1 is fed from a processing machine over rollers 1, 3, 8, through a knot catching fork 9 and an aperture 14 in a cutter housing 15 to a pair of feed wheels 37 in a cutting machine 38. The piston-rod 18 is slidable in the housing 15 and prevented from rotating therein by means of a guide 20 cooperating with a rod 21, the guide also serving as an abutment for the spring 16. With the valve 31 in the position shown air is fed from a supply source 33, pipes 32, 30, vent valve 29 and pipe 28 into a chamber 27 in the cylinder 25 thereby loading the spring 16. In the event of a knot contacting the fork 9, the latter is deflected so as to actuate a switch 13 in an electrical circuit to a solenoid 34 connected to the valve thereby changing over the position of the valve. Air is then fed into a chamber 25 and the chamber 27 exhausted so that the cutter suddenly moves to cut the thread. Further switches 7 and 41 are included in order to actuate the cutter when excessive tension in the yarn raises a roller 3 or a build-up of shred occurs in the cutting machine 38.

Title: Heat-engineering apparatus for carrying out thermo-dynamical processes comprising a pair of mutually opposite phase transitions of a work medium.
IPC: B01D3/06
Filed: 1981-08-21
Abstract: Thermo-dynamical processes which comprise mutually opposite phase transitions of a work medium are carried out in a heat-engineering apparatus composed of casings (100-102-100). The casings consist of spacers 102 sandwiched by a pair of confining plates 100. A casing encompasses one or a plurality of phase transition compartments which unit pairwise to work chambers in which mutually opposite phase transitions occur. If the phase transition compartments are located in different casings, such casings are abutted against one another flatwise along common confining plates. If complete work chambers are disposed in single casings, there are partitions (112) which subdivide a casing in a plurality of phase transition compartments. In both cases the associated phase transition compartments open directly into one another through an orifice (106) in the confining plate and the partition, respectively. Combinations of various confining plates and spacers permit to build heat-engineering apparatus such as multi-flash and multi-effect evaporators, sorption-type refrigerators and the like by employing and association casings of different types which comprise all auxiliary equipments such as condensing vessels, demisters, pressure reducing means, heat exchangers and the like. Required outputs will be obtained by selecting the number of casings accordingly.
Patent ES-8305091-A1 (ES)
Title: Flywheel propulsion system for automotive vehicles or the like
IPC: F02N99/00
Filed: 1981-12-23
Abstract: A propulsion system for use in automotive vehicles wherein the flywheel is connectable with the crankshaft of the internal combustion engine by a first clutch and with the input shaft of the change-speed transmission by a second clutch. When the engine would be idling (such as during stoppage of the vehicle at an intersection) or running unnecessarily for another reason (such as during coasting of the vehicle), the two clutches are disengaged and the flywheel rotates by inertia to restart the engine, when necessary, in response to engagement of the first clutch. If the RPM of the flywheel reaches a preselected lower threshold value, a starter-generator unit automatically accelerates the flywheel so that its RPM rises above the threshold value and is thus sufficient to ensure that the engine is restarted on engagement of the first clutch. The starter-generator unit has a rotor which is mounted directly on the flywheel and a stator which surrounds the rotor with minimal clearance and is connected directly to the housing of the engine. The generator of the starter-generator unit is a heteropolar Schmidt-Lorenz generator.
