Patent ES-350650-A1 (ES)
Title: Ion-producing device
IPC: H01T23/00
Filed: 1968-02-19
Abstract: Uniopolar atmospheric ions for air-conditioning of rooms are produced by discharges at the points of resilient fine wires 2 bearing against the glass body of a gas-discharge tube 6. An electrode 1 supporting the wires 2 is attached by spring clips 3 to the envelope of a fluorescent lamp 6 operated by A.C. or D.C. applied to pairs of terminal pins 10, 11. The electrode 1 is connected to that terminal of a D.C. source which corresponds in polarity to the desired polarity of the ions. The field is so low that little or no ozone, nitric oxide or radio interference is produced. Ionization of the air is enhanced by the UV light in the vicinity of the lamp, and the air is agitated by vibrations imparted to the wires 2 by the lamp.
Patent ES-359184-A1 (ES)
Title: Camera and method for exposing and developing slide transparency units
IPC: G03B17/52
Filed: 1968-10-15
Abstract: In a camera for exposing and processing transparency units each provided with a rupturable pod of processing material, the unexposed units are housed in a storage chamber 10 and moved sequentially into an exposure chamber 11, after which they are developed and then pushed out of the camera through a light-tight slot 36a. As shown, each unit 15 has mounted at one end thereof two rupturable pods 18, 19 containing developing and fixing agents respectively, and held in position by a covering sheet (20), Fig.4(not shown), which is subsequently stripped away together with the empty pods. The units are stacked in storage chamber 10, and urged downwards by a spring 13. The lower-most one is transported into the exposure chamber 11 by a slide 22 having a hooked end 23 and moved by a handle 25. At the other end of the slide is a roller 27. After exposure, the slide is moved back to the right again, the transparency being prevented from moving with it by a spring- loaded locking plate 34. During this return movement of the slide, roller 27 ruptures the first pod 18 and spreads the developing agent therein over the transparency. The slide is now in position to move the next transparency towards the exposure chamber, and as it does so the previous transparency is pushed out through the slot 36a Fig. 5 (not shown). During this movement a second roller 37 provided near the exit slot ruptures the second pod 19, so that the fixing agent is spread over the transparency as it leaves the camera. The covering sheet can now be stripped away, leaving the transparency ready for viewing.

Patent ES-435985-A1 (ES)
Title: Cerebral activity monitor
IPC: A61B5/276
Filed: 1975-03-25
Abstract: A brain wave signal monitor with a warning device actuated by failure of the signals to be present at a preselected minimal level for a specific period of time. The warning device is actuated by a circuit that remains locked in the actuating condition until reset by an attendant. A delay circuit controls the minimum rate by preventing actuation of the warning device until a predetermined time has elapsed since the last brain wave signal. A circuit tuned to the local power line frequency receives signals from electrodes on the patient and provides a second type of warning signal if an electrode becomes dislodged. A third signal circuit is actuated if the power supply voltage drops too low. The second and third warning signals are generated by selectively pulsing a calibration signal generator. The latter also supplies signals of known amplitude to the input circuit. An electrically controlled switching circuit can switch selected electrodes or the calibration signal to the input amplifier.
Patent ES-440582-A1 (ES)
Title: Machine tools
IPC: B23Q3/12
Filed: 1975-08-29
Abstract: There is disclosed a tool storage and changing mechanism comprising a rotatable table tool rack having radial sockets to removably hold toolholders, a horizontal arm, forming a track between the tool rack and the machine spindle, carries a mechanical hand having a forked end to receive from the rack and hold a selected toolholder and carry it to and from the spindle. Assuming that the work with the toolholder has been performed, the empty hand travels to the spindle where, without vertical movement of the arm, the hand grasps the toolholder in the spindle which then releases the toolholder. The arm and hand then descend to withdraw the toolholder from the spindle, after which the arm rises again and the carriage travels back to the rack and deposits the toolholder in its rack socket. When the tool rack is indexed to bring the next tool to the hand, the hand engages the tool and with it approaches the spindle, the arm descends, and, when the toolholder is substantially vertically aligned with the spindle, the arm rises and inserts the toolholder in the spindle where it is grasped by the spindle. Then, without descending the hand is withdrawn from the toolholder and returns empty to the rack. The arm and hand are operated by mechanism including a reversible motor and the above operations are performed in two successive continuous steps, the second being the reverse of the first and resulting from a change in the direction of operation of the motor made between the two steps.

Patent ES-470150-A1 (ES)
Title: Catalytic apparatus
IPC: F01N3/28
Filed: 1978-05-24
Abstract: A catalytic, gas treating apparatus in which a unitary ceramic catalytic element having gas flow passages therethrough, is positioned within a metallic casing in a manner providing a space between the casing and the catalytic element. A resilient member which is compressible both radially and longitudinally is positioned around the catalytic element in said space to resiliently hold the catalytic element. A plug member is positioned at least partially in said space, and, for instance, around the catalytic element at opposite end portions of the catalytic element, in a manner which longitudinally compresses said resilient member to a substantial extent to increase the holding force exerted on the catalytic element by the resilient member and thereby inhibit axial movement of the catalytic element during use. The device avoids the necessity of providing end flanges extending from the casing and overlapping the periphery of the end faces of the catalytic element for the purpose of minimizing axial movement of the catalytic element, and, as a result, essentially all of the gas flow passages remain available to the flow of the gas to be treated and there is maximum catalyst utilization.

Title: Apparatus for making carbon black
IPC: C09C1/50
Filed: 1978-08-25
Abstract: The disclosed apparatus is of the type in which feed units feed air and hydrocarbon material into a reaction chamber, where they react to form carbon black. A filter then removes the carbon black. Disclosed is the provision of a mixing chamber between the feed units and the reaction chamber. The mixing chambers pass through a demountable hollow reactor cover through which there is circulated a heat transfer fluid for controlling the temperature of the mixing chamber walls. The mixing chamber can be common to a plurality of feed units or be separate for each feed unit. Also disclosed is a feed unit which has a vortex plate, an output nozzle, and a hydrocarbon spray nozzle, all mounted on a hydrocarbon supply tube which in turn is fixed to a demountable cover of the feed unit. This permits these components to be readily removed with the cover for replacement or service. The feed units can also have their temperature controlled by the heat transfer fluid for the mixing chambers.
