Patent ES-272881-A1 (ES)
Title: Improvements in or relating to processes and apparatus for conducting gas/liquid reactions
IPC: B01J8/22
Filed: 1961-11-29
Abstract: A suitable solution of an anthraquinone is fed to hydrogenator 1 by downcomer 2 under the pressure of hydrogen introduced at 10. Excess hydrogen is recycled to line 10 via pump 13 and liquid trap 12, while the hydrogenated liquor passes to filter unit 4 leaving by line 5. An unfiltered portion sweeps the catalyst from the filter 7 and returns it with fresh feed or recycle after its hydrogen peroxide extraction step. The feed line need not be a downcomer or a single line while the downcomer can have swirl vanes to assist gas dispersion. All of the gas need not be introduced into the liquid feed line. <PICT:0959583/C1/1>
Patent ES-289970-A1 (ES)
Title: Circuit arrangement for the amplification of a. c. voltages
IPC: H03G1/00
Filed: 1963-07-13
Abstract: In an amplifier which includes a transistor T 1 with a wide-band transformer U as load in its collector circuit, the gain is varied by means of a pair of diodes D1 D2 coupled by capacitor C1 to form a variable shunt across the transformer primary. The diodes are connected in series for D.C., their electrodes remote from the capacitor C1 being earthed for A.C. by capacitors C2, C3. The amplifier V feeds into a detector Dt, the output of which is filtered to remove modulation by filter TP and applied to amplifier GV. This controls the base potential of a transistor T2, the collector current of which passes through the diodes D1, D2 and determines their impedance. A source Q in the emitter circuit of transistor T2 provides delay. The Specification gives a mathematical argument to show that non-linearity in the diodes D1, D2 is compensated by non-linearity of the transistor T2.

Title: Sliding clasp fasteners
IPC: A44B19/36
Filed: 1964-02-17
Abstract: A sliding clasp fastener of the type in which each series of coupling elements is made from a single filament has an end stop comprising a pin 5, 6 or 61 wholly or partly located in the longitudinal channel formed by several of the coupling members 1 at one end of one or both series of coupling members, the thickness of the pin 5, 6 or 61 being such that it is held in place by the frictional forces between the pin and the coupling members.

Patent ES-320553-A1 (ES)
Title: Centrifugal yarn spinning mechanism
IPC: D01H1/08
Filed: 1965-12-10
Abstract: In a pot spinning device a full cake 12 is removed from the pot by an expansible cake holder 13 (see also Fig. 1 not shown) which is rotatable mounted on a vertically movable support 14. When the cake is nearly filled the pot is slowed and support 14 is lifted by a pneumatic device 24, 28, so that the cake holder moves into the pot and a clutch surface 16a thereon engages a clutch surface 1a in the pot so that the cake holder is rotated. A resilient, spirally wound sheet 17 mounted on the spool holder expands centrifugally to engage the inside of the cake. In addition a resilient, air tight sleeve 18 is connected to the air supply to be expanded and engage the inside of sheet 17. When the pot stops the support 14 and the cake holder 13 are lowered to remove the cake from the pot. The support 14 is rotated about a vertical axis to move the full cake to an unwinding position and an empty cake holder to a position beneath the pot, the sleeve 18 on the empty holder being deflated during the rotation.

Title: Apparatus and method for measuring temperatures
IPC: G01J5/52
Filed: 1967-05-10
Abstract: The temperature of a hot body is determined by analyzing the potarization in a beam formed by the radiation from the work piece and the reflection from the workpiece of radiation directed on to its surface by a black body having means for heating it to a temperature which is known, the absence of polarization occuring, according to Kirchoff's theorem when the two temperatures are equal. The combined beam is applied to an infrared responsive photo-conductor through a motor driven polarized disc and the absence of polarization may be detected by the disappearance of alternating current from the detector output or by detecting the point of change of phase. In a modification the motor driving the polarized disc may drive the wiper of a potentiometer to produce a sinusoidal waveform which passes through its maximum when the polarization of the analyzer disc is parallel with the plane of incidence of radiation from the black body. A comparison of the phase of the generated signal with that of the detector output indicates whether the workpiece is hotter or colder than the black body and the valve of the output of a phase discriminator may be used to indicate the temperature difference. The beam is restricted by a small aperture and a wavelength filter, and the apparatus described incorporates a double beam oscilloscope for phase comparison, and signal strength estimation. The black body which is apertured may be electrically heated as desired.

Title: Tractor pto and propulsion clutch assembly including lubrication means
IPC: F16D25/10
Filed: 1973-04-17
Abstract: A tractor transmission includes a hollow PTO input drive shaft having a propulsion input drive shaft located therein, the ends of the shafts terminating adjacent an engine flywheel and carrying PTO and propulsion clutch elements for selectively fixing one or the other or both of the shafts to the flywheel for rotation therewith. The clutch elements are respectively actuated into engagement with a backing plate carried by the flywheel by means of a pair of concentrically arranged fluid-operated pistons. A pilot-operated clutch-lubrication-fluid control valve shifts in response to the operating pressure acting on the pistons to block the flow of fluid to the clutches when both clutches are disengaged, to permit a predetermined amount of fluid to flow to both clutches when both or only the propulsion clutch is engaged and to permit a lesser amount of fluid than said predetermined amount to flow toward the clutches when only the PTO clutch is engaged. A restriction is located in the lubrication fluid passage between the connection of the passage with the PTO and propulsion clutches and the restriction acts to cause substantially all of the lesser amount of fluid to flow to the PTO clutch when only the PTO clutch is engaged.
