Patent ES-359739-A1 (ES)
Title: Method and apparatus for winding yarn
IPC: D01H1/04
Filed: 1968-10-30
Abstract: A package 15 of synthetic plastics tape drawn from a controlled speed supply source is wound on a non-rotary support 34 by a winding guide 47 (e.g. on a flyer 12) driven round the axis of the support so as to insert one turn of thrust for each revolution of the guide. Thus when the tape is drawn off over-end e.g. in a loom, the drawn-off tape is twistless. As shown spindle 14 carrying the flyer is driven from a pulley 26 which transmits drive to a clutch plate 29 on the spindle through friction pads 28. Pads 28 are radially movable so that as the package grows the torque applied to the spindle is lessened and the tension in the tape is kept constant. Other types of slipping drive may be used. The tape passes to the flyer over a pulley 45 close to the top shoulder 46 of the flyer thus each twist inserted in the tape is localized. The flyer is provided with a selfthreading guide roller 47 and a co-operating pivoted wire arm which lays the tape on the package. The packags build is derived from the reciprocation of a rail 20 and associated shaft 40, the reciprocation being transmitted by a bar 38. To obtain shaped package ends shaft 40 is intermittently rotated so that a gear thereon engaging a rack on bar 38 shifts bar 38.

Filed: 1969-05-27
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: Method and apparatus for heat treating with heat recuperation from material cooling and auxiliary heat during startup
IPC: C22B1/216
Filed: 1973-10-04
Abstract: A method and apparatus is disclosed for heat treating mineral ore materials. The apparatus includes, in material series flow arrangement, a traveling grate preheater having at least one material drying zone and a preburn zone, a rotary kiln, and a cooler. The cooler has a first stage in which air becomes heated as the ore is cooled and this heated air is conducted through the kiln and preburning zones counter to material flow. The cooler has a second stage in which air is heated and thermal energy recuperated as the ore is further cooled and this second cooler stage air after being heated is conducted by a bypass conduit around the kiln and preburn zone to supply heat for drying the materials. An auxiliary air heater is associated with this bypass and according to the method disclosed, during start-up operation and before hot material arrives in the second stage of the cooler, the air heater is operated to heat the air conducted from the second stage of the cooler, for drying the material until hot material does arrive in the second stage of the cooler and thereafter heat transferred from the hot material to the air passing through the material in the second stage of the cooler, is utilized for drying the material. The disclosed apparatus operated according to the disclosed method, achieves improved fuel economy, more effective control of the drying or dehydrating operation, and such operation is achieved with a smaller kiln than heretofore required according to teachings of the prior art.

Title: Method of, and apparatus for, manufacturing a video record
IPC: G11B7/24097
Filed: 1976-09-22
Abstract: When the information of a continuous-motion video record is displayed in the stop-motion mode by repeated display of two fields which form an interlaced picture, motion in the scene gives rise to a frame-frequency flicker phenomenon in the stop-motion picture. By forming suitable video signal combinations in discrete groups which each comprise two associated fields and by recording these combinations in the video record, the flicker phenomenon in a stop-motion picture is eliminated without continuous display being perceptibly affected.

Title: Plastics valve with positioning handle
IPC: F16K37/00
Filed: 1976-11-30
Abstract: The actuating device of the valve (12) has an actuating extension (31) which is connected to the valve-closing element (16) via a connecting section (36). The connecting section is designed in such a way that it acts as a predetermined breaking point before impermissibly high forces can act on the valve-closing element, causing leaks. By means of a particular arrangement of the working surfaces of the actuating extension, which extend parallel to the axis of rotation, the valve can be operated by various tools. Towards the top, the actuating extension (31) has bevelled surfaces which serve to deflect impact forces. The actuating device is particularly advantageous for valves made of plastic installed in underground gas distribution pipes.
Patent ES-455322-A1 (ES)
Title: Dispersion or suspension of solid phase in liquid phase
IPC: B01F23/57
Filed: 1977-01-25
Abstract: The inventive method uses a continuous mixer for making dispersions or suspensions of a solid phase in a liquid phase. The solid and liquid phases are fed continuously into the mixer at respective input rates resulting in a combined proportion of solid phase to liquid phase. The combined phases are continuously formed into a third phase as a plastic-consistency layer extending all around the mixing region. The third phase is thick enough in its plastic consistency for continuously receiving the solid and liquid phases and preventing their passage through the mixing region until they are homogeneously mixed together. The third phase is thoroughly mixed until it changes from its plastic consistency to a substantially more flowable fourth phase capable of continuous output flow from the mixer.
