Patent ES-443881-A1 (ES)
Title: Yarn measuring instrument
IPC: G01P3/50
Filed: 1975-12-26
Abstract: A yarn measuring instrument having a rotatably mounted operative element whose rotation in response to frictional engagement thereof by travelling yarn cooperates with electronic circuit means to measure a plurality of characteristics of the travelling yarn is provided with means for capturing the travelling yarn and placing it in frictional engagement with the operative element. The yarn capturing means includes an arm which has a free end provided with yarn retaining means. The arm is mounted within the instrument for movement between a projected position thereof in which the yarn retaining means extends outwardly of the instrument and a retracted position thereof in which the yarn retaining means extends inwardly of the instrument, whereby travelling yarn captured in the retaining means when the arm is in its projected position automatically frictionally engages the operative element when the arm is moved to its retracted position.

Patent ES-454670-A1 (ES)
Title: Method of operating an electrochromic display device
IPC: G02F1/17
Filed: 1976-12-29
Abstract: A display panel having electrodes which define display points or symbols to be represented is filled with an electrochromic substance which visibly changes its optical properties under the action of an electric field. Drive circuits selectively deliver current pulses to selected electrodes in order to trip visible changes in the substance. For this purpose, the novel operating method uses, in a time-division multiplex mode, a sequence, interrupted by recovery pulses, of short current pulses of an intensity that is lower than usual to date. Because disturbing saturation effects now no longer occur, the total time for the display is nevertheless shortened.

Title: PROCESS FOR THE MANUFACTURE OF UREA-HCHO-isobutyraldehyde condesnation products and compositions thereof
IPC: D06M101/08
Filed: 1977-09-02
Abstract: This invention describes a process for the manufacture of condensation products and compositions obtained thereby. The condensation products are prepared by the reaction of 2 to 3 moles of urea with 0,9 to 1,1 mole of formaldehyde and 1 mole of isobutyraldehyde in the presence of 0,2 to 1,0 equivalent of strong acids and 4 to 18 moles of water. The pH-value of the resulting products is adjusted to 7 to 9,5 and the water is partially to almost completely removed. Then the products are methylolated with 3 to 4 moles of formaldehyde. Finally the condensation products are etherified with low alcohols in usual manner. Used singly or together with other N-methylol compounds and their ethers with low alcohols, the products are useful compositions which are capable of rendering cellulosic textile materials and blends with synthetic fibres crease- and shrinkproof.

Title: Parachute with canopy opening assist and opening control
IPC: B64D17/34
Filed: 1978-06-20
Abstract: The parachute opening assist and control arrangement is a small auxiliary canopy in combination with a series of transverse reefing lines. The auxiliary canopy is folded within the main canopy and is connected to the reefing lines. Each reefing line is connected between two opposed main support lines. When the parachute is fully open, the reefing lines are a series of transverse lines which cross each other at a central point. The ends of the reefing lines are connected to the main support lines at a point close to the skirt of the main canopy. The auxiliary canopy extends above the reefing lines. A positioning line is connected between the crown of the main canopy and the center point of the reefing lines. The positioning line may be foreshortened to increase the reefing effect during canopy opening. The auxiliary canopy and reefing lines together increase the speed of initial opening and control the opening to reduce the maximum shock during opening.

Patent ES-474432-A1 (ES)
Title: Gas-blast switch
IPC: H01H33/56
Filed: 1978-10-23
Abstract: A gas-blast switch having a hollow support insulator, and and at least one switching chamber housing supported thereon and within which there is arranged a set of fixed contacts, surrounded by a blast chamber, and a set of movable contacts. A blast nozzle coacts with the movable contacts and is connected with a pump device having a pump cylinder surrounding a pump chamber and movable with the movable contacts. The pump cylinder is displaceably arranged upon a stationary piston. A check valve opens towards the pump chamber. During the cut-on stroke pressurized gas is sucked by the valve into the pump chamber. The latter is connected by the check valve with a supply compartment communicating via inlets with the blast chamber and the internal space of the support insulator. A further valve is responsive to the pressure increase in the blast chamber, which valve, when responsive, interrupts the connection between the internal space of the support insulator and the inlets. The supply compartment is preferably formed by a cylindrical hollow body whose one end face serves as the pump piston, whereas at the end region of the outer surface of the hollow body furthest from such piston there are formed the throughpassages or inlets as axially lengthwise extending slots. The valve may be a plate valve whose valve plate coacts with a valve seat affording access to the internal space of the support insulator and further, in its open position, subdivides the inlets into two sections, one opening into the supply compartment, the other by means of the valve seat into the internal space of the support insulator.

Patent ES-476628-A1 (ES)
Title: Method and apparatus for controlled-temperature valve mode transfers in a steam turbine
IPC: F01D17/24
Filed: 1979-01-05
Abstract: An electrohydraulic control system and method are disclosed for operating valves controlling the admission of steam to a steam turbine. The system includes a mode transfer unit for effecting a transfer between a full arc mode of valve operation to a partial arc mode of operation such that the temperature of the steam turbine varies in a controlled manner, thus permitting control of turbine stresses. Apparatus is described for generating mode flow signals, combining the signals using time ratio switching such that during a mode transfer the signals vary linearly with an admission reference factor characteristic of each mode, and generating valve lift signals from a combined flow signal using multi-slope, piecewise linear approximations to the flow-lift characteristics of the full arc mode of valve operation. The system permits mode transfers wherein total steam flow is held substantially constant and first stage turbine temperature is caused to vary linearly with admission reference factor.

Title: Automatic device and process for tightening and untightening a nut on a tension bolt.
IPC: B23P19/06
Filed: 1979-09-26
Abstract: Stud bolts are threaded into the body of a nuclear reactor vessel and tensioned by exerting forces on tensioning nuts located on the upper end of the studs. While the studs are under tension, a cover is attached to the vessel by tightening nuts on the studs against the cover. The tensioning nuts are applied to the studs by immobilizing the studs axially and rotationally, and rotating the tensioning nuts with a pair of driven, diametrically opposed striking rollers. External threads on the striking rollers, external threads on the nut and internal threads on the nut all have the same pitch so that the threads on the striking roller remain engaged with the external threads on the nut as the nut moves axially while being threaded onto the immobilized stud.

Patent ES-8203480-A1 (ES)
Title: Pressure responsive disconnecting fluid, coupling and shut-off valve.
IPC: F16L37/62
Filed: 1980-07-24
Abstract: A fluid coupling and shut-off valve (1) for insertion into a fluid pressure line, the coupling (1) having a body (2) a pressure connecting piece (3) and a coupling piece (8). The body (2) includes a pressure actuated thimble (19) which engages catches (14) to lock the coupling piece (8) in the body (2). Reduction of pressure in chamber (34) due to reduced pressure in the supply line (4) causes the spring (23) to move the thimble (19) and release the catches (14). The spring (33) then moves plunger (26) to eject the connecting piece (8) and thus prevents fluid flow through the coupling (1) when the valve member (27) engages the seat (25).

Title: Electrostatic spray gun apparatus.
IPC: B05B5/025
Filed: 1981-11-16
Abstract: A hand manipulable spray gun has an air turbine (37) which is driven at high speed in the order of 60,000 rpm and drives directly an alternator (38) to generate an alternating voltage in the order of 50 volts at about 1000 Hz.
