Patent ES-356615-A1 (ES)
Title: Circuit interrupter having dual-bore arc extinguishing means
IPC: H01H85/042
Filed: 1968-07-29
Abstract: A circuit interrupter 100 comprises a tubular insulating casing 32, annular blocks of arc extinguishing material 122, 124, 126, 128, e.g. of boric acid housed in casing 108, each having aligned large and small bores 130, 192 with a conducting rod 83, 182 disposed in each, each block having in its face contracting other blocks a recess (126b in Fig. 3, not shown), extending around and spaced from the small bore 192, each recess having an opening to the periphery of the block, a bonding material, e.g. epoxy resin, filling adjacent pairs of said recesses. The fuse unit 100 is supported by insulators 272 and 282 with contact 250 latching the upper terminal 34 and contact 260 pivotably supporting lower terminal 36. Conductive elements 160, 162 and 194 connect the rods 83 and 182 to terminal means 150. The fusible element 160 is of lowest resistance of the three elements and under overload conditions fuses first, followed by strain member 162. When strain member 162 fuses the conductive rods 83 and 182 joined by pin 184 at their top ends are moved upwards under the influence of spring means 76, stretching the helically coiled wire 194 until it either fuses as it is carrying the full current or else is mechanically broken. Arcing will take place at this breakage and will usually occur between the end of the rod 182 and the arcing terminal 158, which is coated with a thin layer of insulating enamel. When interrupting low currents, e.g. less than 1000 amps the arc will be extinguished by gases produced in the arc extinguishing material of the small bore 192, but with larger currents the arc may then restrike in the main bore 130 from the retreating end of rod 83, where it is normally extinguished. The epoxy filled recesses around the small bore prevents ionized gases from travelling between bores. With still higher currents the temperature and pressure in the box may rise to a dangerous level in which case the thin walls 126A and 128A between C-shaped recess 129 and the bore 130 will rupture to reduce the pressure. The conductive rod 83 is connected to the upper terminal 36 by flexible cables 82 and conductive member 60. When the spring collapses after fusion of the strain member, the member 74 to which the upper end of the spring is secured slides over the member 60 under the reaction of the spring and pin 56 which is secured to the spring moves in slot 62 of member 60 and tripping member 52 integral with the pin 56 moves through the hole 46 in cap 44. The tripping member 52 detaches the latching means 250 and fuse unit 100 drops out of contact with the upper contact pivoting on the lower terminal means 260. Pivotable means 274 is provided on the upper terminal 34 to allow opening and closing of the connection through the fuse unit using a hook stick.
Patent ES-357379-A1 (ES)
Title: Automatic feeding and cleaning installation for pig farms
IPC: A01K1/01
Filed: 1968-08-19
Abstract: A building for housing pigs has automatic feeding, watering and dung clearing means. The stable has two rows of pens 1 defining a control passage 1a along which a feeding hopper 3 travels, and two dunging passages 1b. A control room 1c is isolated from the stable by automatically controlled motor driven doors 25. The feed hopper is filled from silo 24 by a screw conveyer (24a), Fig. 7 (not shown), the filling being controlled by a micro-switch. The food supply is regulated by a turbine 19, Fig. 9,in a shoot (23), Fig. 8 (not shown), of the hopper 3. The turbine is rotated by a star wheel 14 turned by pegs 15 in rail 16 which control the quantity of food dispensed. The star wheel drives turbine 19 via gears 17 and shaft 18. The star wheel has a ratchet so that food is only supplied as the hopper moves away from the control room. Water is supplied, for mixing with the food, from tanks (7), Fig. 6 (not shown), in each pen. The water level in the tanks is controlled by adjustable ball valve (34a). As the food hopper advances a roller 11 carried by an arm 9, Fig. 5, mounted on the feed hopper 3 actuates a valve 38a via a plate (12), Fig. 6 (not shown) in order to supply water to the food in the trough. The roller only actuates the valve when in position b, Fig. 5. When the feed hopper reaches a position remote from the control room, arm 9 is raised by a stop 13. On returning to the control room, arm 9 is lowered by stop 131. Dung channels 1b, Fig. 1, are cleaned by scraper blades 30, Fig. 7, carried on trolleys 29. The scraping action occurs in one direction of movement of the trolleys only, the blades being brought into and out of engagement with the floor by means of stops 33, 331, at each end of the dunging passage. The feed hopper 3, Fig. 1, may be driven by steel cables 4, Fig. 3 (not shown), or by an electric motor on the hopper. The dung trucks are driven by endless belts passing over pulleys 271, 27.
Patent ES-361035-A1 (ES)
Title: Apparatus and method for cooling extruded molten filaments
IPC: D01D5/088
Filed: 1968-12-04
Abstract: Quenching apparatus suitable for cooling molten synthetic polymer filaments extruded from a substantially circular spinneret assembly 18 (Fig. 2) comprises an enclosure 1 defined by end walls 2 and 3, side walls 4 and 41, and a front wall comprising front side sections 6 and 61 and a longitudinal concave foraminous surface 7 extending into the enclosures. As shown, surface 7 is held in place by longitudinal strips 8 and 81 and concave strips 9 and 91, and may be a wire screen, perforated sheet metal, a combination of both or any other air distributing foraminous surface. The curved perforated wall 11, mounted between the front wall and back wall of the enclosure, ensures a more even distribution of air or other gas from supply inlet tube 12, which extends from back wall 5 and is adapted for telescopic connection with tube 13, which extends into plenum chamber 14. Key 15, attached to the under side of tube 12, slidably engages slot 16 of tube 13. Orifices 17 in tube 13 facilitate gas flow into tube 12. In a modification, not shown, the gas inlet supply is connected to the bottom or back of the quenching apparatus, baffles serving to distribute the cooling gas. The quench device may also be mounted to slide up and down relative to the spinneret. The quenching apparatus is so designed as to be capable of being positioned as close up to the face of circular spinneret assembly 18 as possible, as shown in Fig. 2, in order to solidify the filaments more quickly. The semi-circular foraminous surface of the quenching apparatus produces a semi-radial horizontal flow of cooling gas across the filaments without a corresponding concurrent flow of the gaseous medium with the extruded filaments, thus obviating the type of turbulence encountered with cylindrical quenching apparatus, where the gas currents meet at the centre of the filament stream. In addition, access to the spinneret for cleaning and lacing is facilitated, and quenching results are found to be superior to those obtained using straight wall quenching. Quench gas velocities of about 9 to 30 metres per minute are used, the lower velocities being preferred for lower denier yarns, and the higher velocities for higher denier yarns. Examples illustrate the spinning of polyethylene terephthalate filaments.

Patent ES-373656-A1 (ES)
Title: Manufacture of glass having desired surface characteristics
IPC: C03B18/14
Filed: 1969-11-18
Abstract: In the manufacture of float glass having a predetermined light and heat transmission and tub, in which a locating body of molten alloy of at least two metal elements is in contact with the upper surface of the glass as it floats on a bath of molten metal and the temperature of the glass is regulated so that it is receptive to electrolytic modification and which temperature determines the desired relative proportions of the elements from the alloy body which enter the glass surface, a voltage is applied between the alloy body and the bath of molten metal so that current passes from the alloy to the glass, the voltage being regulated in relation to the thickness and temperature of the glass, the composition of the alloy and the time of treatment to enforce an electric flux density which produces sufficient ionic migration of each element across the alloy/ glass interface to give the desired transmission characteristics. The time of treatment is controlled by the length of the alloy body in the direction of advance of the glass. Temperatures can be varied as by heating the glass surface just before treatment. The alloy body may be separately heated or cooled to vary the proportions of the alloy, as for example, a.Cu/Pb alloy, with additional metal available, will contain more Cu at higher temperatures. The alloy is preferably clinging to a locating member comprising one of the metals and this then acts to replenish that metal. Replenishment of either metal may be by a controlled feed of pellets to the locating member where they melt in an aperture therein. After treatment may include passing through a reducing atmosphere where the degree of colloidal dispersion of the elements in the glass is regulated to vary the light and heat transmission characteristics. Suggested locating members are of copper, molybdenum, tungsten or ruthenium for coppertin or copper-lead alloys or silver or ruthenium for silver-lead alloys. Specifications 1,151,853, 1,211,854 and 1,272,222 are referred to.
