Patent ES-347527-A1 (ES)
Title: Improvements in or relating to Fluid Pressure Transmission Means for Use on Machine-tool Heads
IPC: F15B13/01
Filed: 1967-11-23
Abstract: A rotary machine tool head 1, 2 having a fluid operated actuator piston 16 for operating a chuck, is provided with a rotary part 3 which includes a valve assembly, Fig. 4, supplied with oil under pressure when the actuator is to be operated and arranged to trap oil in the actuator when the oil supply is cut-off. The actuator piston 16 slides in a cylinder defined by the rotary parts 1, 2, 3 and divides the cylinder into chambers 15, 23. The oil is trapped in these chambers when the oil supply is cut-off and hence the actuator is locked in its adjusted position. To operate the actuator oil is supplied to the valve assembly through one or other of ducts 11, 21 by selective pressurization of annular grooves 9, 19 in a stationary block 4. Assuming the duct 11 is pressurized, then the right hand non-return valve 37 opens to allow oil to flow through ducts 12, 13, 14 into the actuator chamber 15. The increase in the oil pressure in the duct 11 causes leftwards displacement of a piston 27 and consequential opening of the left hand non-return valve 37 so that oil in the opposite chamber 23 exhausts through ducts 22, 21. If the duct 21 is pressurized, oil flows to chamber 23 for operation of the actuator in the reverse direction.

Abstract: The power supply for an arc welding system wherein an arc x is maintained and a droplet on the end of an electrode periodically contacts a weld pool, includes first and second D.C. power sources G and S, supplying the workpiece and electrode, in parallel. The first source has a short-circuit current note of rise less than 60,000 (preferably between 15,000 and 40,000) amperes per second and a voltage output sufficient to maintain an arc between the electrode and workpiece for drop formation. The second source has a short-circuit current rate of rise in excess of 60,000 (preferably between 100,000 and 1,000,000) amperes per second and a voltage output such as to supply substantially no current when an arc exists and a pulse of current when the droplet still on the end of the electrode contacts the weld pool. As shown, the workpiece W and motor-driven electrode E are connected to respective terminals CT, CP to which the first and second sources, G and S, are connected. The second source is an alternator A on the same shaft as the first source generator G, the alternator being connected through a three-phase rectifier bridge 41. The generator G is controlled by a settable voltage regulator R which can be connected to the terminal CT, CP and controls the field windings 33 of the generator G. The regulator R can also be connected across a resistor 44 in the field winding circuit when the second source S is disconnected. Alternatively the first source G may be batteries with an inductance or rectified A.C. supply with an inductance of D.C. from a rotating generator with or without an external inductance. The second source S may also be a battery or current transformer with a rectifier.

Title: Anchor-cable systems
IPC: B63B21/24
Filed: 1969-12-24
Abstract: An anchor for mooring a vessel to a mooring bed includes at least one fluke attached to a shank part of the anchor and inclined relative thereto to cause penetration of the anchor into the mooring bed on horizontal movement of the anchor. Stabilizer fin (or fins) is mounted on an extension of the shank part and spaced from the fluke such that, on penetration of the anchor into the bed, any pivoting of the shank part to decrease the angle of attack of the fluke relative to the bed is counteracted. Also, the anchor-cable may include at least one fin device adjacent the anchor, the fin of the device being inclined such that burial forces are produced by the device to counteract the vertical penetration resistance of the adjacent cable and to constrain the buried portion of the cable to depart from the usual catenoidal configuration and adopt a linear or adverse curvature configuration.

Title: Quick heat treatment of steels
IPC: C21D6/00
Filed: 1973-03-07
Abstract: An elongated steel workpiece is quickly heat treated in a single heat treatment, by passing it between spaced electrodes and applying a current to the steel between the electrodes thereby to heat it above the austenitic transformation temperature at a heating rate of at least 50 DEG per second, preferably 200 DEG to 100,000 DEG C. per second, holding it at such annealing temperature for at most 300 seconds, preferably 0.04 to 3 seconds, so as to recrystallize the ferrite while dissolving substantially none of the carbides.

Patent ES-415860-A1 (ES)
Title: Rotating electrical machine having rotor and stator cooled by means of heat pipes
IPC: F28D15/02
Filed: 1973-06-13
Abstract: A polyphase induction motor having a rotor and a stator, each having heat pipes incorporated therein, is disclosed. The stator is comprised of a stack of laminations having radial slots therein which contain heat pipes as well as electrical conductors. The stator heat pipes are located in the stator slots and extend axially to a remote location beyond the stator and the rotor. The stator heat pipes contain wicks and contain a two-phase fluid coolant. The rotor is also comprised of a stack of laminations with radial slots located in the outer periphery thereof. Heat pipes are incorporated in the rotor slots and, like the heat pipes in the stator slots, extend axially to a remote location beyond the rotor and the stator. The rotor heat pipes also serve as electrical conductors as well as heat exchangers for cooling the rotor. Thus, all of the rotor heat pipes are electrically interconnected by end rings located at the axial extremities of the rotor. The rotor heat pipes also contain a two-phase fluid coolant. However, because centrifugal force promotes condensate return within the rotor heat pipes wicks need not be used in the rotor heat pipes. Cooling fins are provided on those sections (condenser sections) of the heat pipes which extend axially beyond the rotor and the stator thereby forming air heat exchangers. Moreover, the fins on the moving rotor heat pipes act as moving fan blades and, being located proximate to the cooling fins on the stator heat pipes, effectively form a single-pass, forced-convection, air heat exchanger.
