Patent ES-290842-A1 (ES)
Title: Roll changing apparatus
IPC: B21B31/10
Filed: 1963-08-14
Abstract: Apparatus for use in changing the rolls of a mill having at least two rolls comprises a rollcarrying car 24 mounted on rails 33 and having two vertically spaced roll platforms and an assembly 36 for moving the rolls on to and off the platforms, the assembly being movable through an open side of the car 24 to approach the mill. To remove the rolls 12 and 13 from a mill 9 a frame 37 is shifted by a cylinder 49 into one roll platform of the car 24, both the car and the frame being recessed to avoid contact with a projecting wing 14 of the mill, the wing having a vertical roll. Hooks 38 and 40 on the frame engage hooks 39 and 41 on the roll chocks and the roll assemblies are withdrawn to the left. The upper roll assembly slides along a supporting beam 19 on to an upper platform of the car, while the lower roll assembly slides on to a lower platform. The car is then shifted by a cylinder 34 along rails 33, parallel to the pass line, until replacement roll assemblies 12a and 13a, housed in a second bay of the car, are in line with the mill. These assemblies are moved by the frame 37 into the mill. If required, a single roll can be removed from a mill using a ar having only one platform.
Patent ES-303965-A1 (ES)
Title: Improvements in or relating to turbine plants
IPC: F01K7/44
Filed: 1964-09-11
Abstract: A turbine power plant includes a higher pressure main turbine supplying a lower pressure main turbine through a reheater, an auxiliary turbine receiving working fluid from the higher pressure main turbine and driving a liquid feed pump, and an automatically controlled flow regulating valve in the conduit between the main turbines arranged to throttle the working fluid flow at low power outputs from the main turbines so as to ensure a sufficient supply pressure of working fluid to the auxiliary turbine. A superheated steam generator 5 supplies high and low pressure main turbines 1H, 1L respectively through an admission control valve 11 interstage reheater 7 and regulating valve 13. An auxiliary turbine 31 driving a feedwater pump 33 receives steam from H. P. turbine 1H through a regulating valve 37 and exhausts to feedwater heater 23. Feedwater heaters 19, 23, 27, 35 also receive bleed steam from the turbines. Over the upper range of main turbine load 3, valve 37 controls auxiliary turbine 31 output in response to feed pump delivery pressure, feed flow, or boiler drum water level. When the main load drops such that turbine 31 tends to receive insufficient steam, unit 39 resets interstage valve 13 so as to throttle the main steam flow and cause a corresponding increase in the inlet pressure at turbine 31. Unit 39 may be responsive to a feed pressure sensor 41, feed flow, boiler conditions, H. P. turbine exhaust pressure, or main turbine output. A small electrically driven stand-by feed pump may supplement or supplant pump 33 at the lowest main loads.

Title: Polymerization of vinyl chloride in mass
IPC: C08F14/06
Filed: 1967-04-21
Abstract: The bulk polymerization of vinyl chloride at - 40 to + 40 C. is effected in the presence of an initiator of the formula in which X is halogen and Y is hydrogen or halogen and R is a saturated or unsaturated aliphatic hydrocarbon radical of 1-9 carbons (including any substituents), a cycloalkane, cycloalkene, aromatic or heterocyclic radical or such a radical containing substituent groups.

Title: Improvements in and relating to Mechanisms for Axially Clamping a Cylinder Liner or the like between an External Housing and an Associated Cover.
IPC: F16J13/12
Filed: 1968-05-31
Abstract: A cylinder liner is clamped between a face 3 and a cover 7 by an hydraulic ram 6 and an annular nut 15 which engages in an internal screwthread of the cover. The ram is supplied at 10 with fluid through a duct 13 from a hand pump and the nut subsequently screwed down to abut the back face 16 of the ram.

Patent ES-359582-A1 (ES)
Title: Speed controller
IPC: G05D13/00
Filed: 1968-10-14
Abstract: In order to retroactively control the speed of a rotating machine 19 over a wide range, a special tachometer generator is employed. The latter employs a rotatable permanent or electromagnet 11 and a rotatable annulus 12 carrying a pick up coil 13. One of these is coupled to the machine 19 and the other driven by a motor M. When the machine 19 is required to run at its rated speed the annulus 12 is stationary and the system acts like a conventional tachogenerator system the output frequency of coil 13 being converted to a voltage in discriminator 30 and compared with a reference 32 to control a valve 20 adjusting the speed of the machine. The reference 32 is normally fixed but a small variation in speed can be provided by altering the reference. When, however, it is required that the machine rotate at a speed well removed from its rated speed the annulus 12 is rotated at a speed corresponding to the difference between the rated and derived speed so that the output frequency of coil 13 is proportional to the difference between the speeds of motor 14 and machine 19 and valve 20 adjusts the speed to the new desired speed (the reference 32 still being the rated speed). The speed of electric motor 14 is controlled by a further loop, including tachogenerator 15, according to a speed setting device 16.

IPC: F02M59/36
Filed: 1972-03-22
Abstract: Method of and apparatus for filling a piston fuel injection pump of internal combustion engines with fuel. The fuel is fed through a side filling channel into a space over the piston which is under negative gauge pressure during the movement of said piston to its lower dead center, as well as during its movement toward its upper dead center until the filling channel is covered by the edge of the piston at the moment when there is still negative gauge pressure in the area above the piston. During the subsequent displacement of the piston to the upper dead center, the negative pressure in said space disappears and the fuel starts being discharged into the delivery conduit. The volume of fuel flowing through the filling channel is adjustable by varying the entering pressure of the fuel.

Title: Steam separator
IPC: F24F6/18
Filed: 1974-07-22
Abstract: A steam humidifer including a separator for separating water from wet supply steam and a dry steam distributor. The separator includes a chamber having a conical water separating baffle therein which, according to a preferred aspect of this invention, defines an included angle of 70 DEG . A wet steam inlet conduit changes the direction of the incoming steam 90 DEG and directs it toward the baffle, where water is separated from the steam as it impinges and passes along the conical surface of the baffle. After passing along the baffle, the steam direction is reversed 180 DEG with respect to the incoming steam direction and the dry steam exits the separator through an outlet conduit. Dried steam passes into the atmosphere to be humidified through a ported manifold distributor tube. A portion of that tube is jacketed by a portion of the wet steam inlet conduit to heat the steam in the distributor tube and to thereby maintain its dryness. The outlet tube is provided with a blind branch tube or re-evaporation chamber which terminates in the separator to trap any remaining water associated with the dried steam.

Title: Transport device for reactor fuel rod cladding tubes
IPC: B65G47/28
Filed: 1974-12-27
Abstract: A device for transporting nuclear fuel rod cladding tubes transversely along a production line has a travel surface for the tubes and a transport chain running in the direction of transport parallel to the travel surface. The chain has a plurality of two-armed levers pivotally mounted thereon and springs pulling these levers in the direction of the travel of the chain. The levers have rollers at their ends which can engage between tubes on the travel surface. The springs are of such strength that the resistance to movement of a predetermined number of tubes prevents them from rising up, so that the rollers roll underneath the tubes, but permits them to rise up when a small number of tubes is in front of them to engage the tubes and pull them along the track. This provides in effect a storage if too many tubes are found on the track at any one time.
