Patent ES-422445-A1 (ES)
Title: Operator viewing optics for a slide classification system
IPC: G02B27/28
Filed: 1974-01-19
Abstract: In a system producing an electrical output representing the characteristics of a blood smeared slide, an optical system permits an operator to comfortably view the slide while it is being intensely illuminated. A television type detector produces the electrical output representing the optical characteristics of the blood on the slide. This detector requires that a very intense source of light be applied to the slide. In order for the operator to simultaneously view the slide a duplex beam splitter is inserted in the light path. A first prism in the beam splitter diverts a small percentage of the intense light to the operators viewing eye pieces. The first prism is a 30 DEG -60 DEG - 90 DEG prism having an index of refracton such that the reflection from the second surface is directed out of the prims and away from the viewing eye piece to avoid ghost images. A second prism having the same geometry and index of refraction re-establishes proper direction of the light beam between the slide and the detector. The small portion of light directed from the first prism to the viewing eye piece is predominantly polarized in one direction. The degree of polarization is easily calculated by Fresnell's law. A linear polarizer between the first prism and the eye piece is adjustable to provide continuously variable light attenuation. Adjustment of the linear polarizer through 90 DEG rotation is sufficient to achieve the full light attenuation range.

Title: On-line carbon dioxide analyzer and analyzing method
IPC: G01N33/14
Filed: 1975-04-29
Abstract: Apparatus and method for determining the amount of carbon dioxide in continuously supplied liquids containing dissolved carbon dioxide, such as wine or other beverages. A constant-flow sidestream of the liquid is ejected in the presence of a carrier gas which dissolves carbon dioxide into a separating chamber under conditions which yield substantially instantaneous and substantially complete evolution of carbon dioxide from the liquid. The carrier gas and evolved carbon dioxide are conducted from the chamber to a carbon dioxide measuring and recording device, and the separated liquid that is depleted of carbon dioxide is drained from the chamber.

Title: Magnetically actuated viscous fluid coupling
IPC: H01F7/08
Filed: 1977-04-27
Abstract: A viscous fluid clutch employing a magnetic field selectively actuatable by a heat sensing device to operate a valve arm to seal an inlet passage fluidly communicating an operating chamber with a storage chamber. The clutch includes a clutch and a housing member rotatably disposed relative to one another. Each member has a shear surface. The surfaces define therebetween the operating chamber. The storage chamber is located in the housing member and is in fluid communication with the operating chamber via a discharge passage and the inlet passage. Pump means in the operating chamber displace fluid through the discharge passage from the operating chamber to the storage chamber. The inlet passage directs fluid from the storage to the operating chamber. A movable valve arm selectively seals the inlet passage. The valve arm is moved via a solenoid action in response to actuation of the magnetic field. Fluid is disposed within the clutch and is used, when located in the operating chamber, to rotate the housing members in response to rotation of the clutch member. When the fluid is displaced from the operating to the storage chamber, rotation of the housing member is reduced.

The same motor also powers the drum for winding or unwinding the hose, a selector clutch being provided. A combustion engine may replace the hydraulic motor for driving the wheels, the motor powering the drum only.
Patent ES-461456-A1 (ES)
Title: Gas panel single ended drive systems
IPC: G09G3/28
Filed: 1977-08-09
Abstract: A system for addressing and controlling a gaseous discharge display or memory device is adapted for intercommunication between a processor or controller and a gaseous discharge display device. Signals of write amplitude are selectively applied to ionize individual cells or a plurality of cells in the form of character slices or lines to form the elements of a display. To facilitate communication between low level control logic signals and high level write and sustain signals, one of the axes or sets of conductors is maintained at ground potential, while signals of full write or sustain amplitude are applied to the orthogonal conductors. Writing is generally accomplished by adding a write pulse to the trailing edge of the selected conductor. By maintaining the busier axis at ground potential direct communication between the control logic and drive circuitry is provided, the isolation circuits required to communicate between the busy axis and the controller or processor are eliminated, the separate sustain drivers normally required to sustain the busy axis are eliminated and only a single set of drivers and isolation circuitry is required to interconnect the control logic to the drive selection circuitry. By operating in this mode, the sustain signal is not interrupted during a write operation thereby permitting use of the inherent margin in the panel and providing a display of uniform intensity.

Patent ES-482805-A1 (ES)
Title: Adjustable compensation means for the phase angle of electricity meters.
IPC: G01R11/20
Filed: 1979-07-24
Abstract: A phase-angle adjusting device for electricity meters having a short-circuit winding (3) surrounding both legs of the current core (1) is constructed in such a manner that the short-circuit winding (3) surrounding the two legs and the adjustment loop (6) located in series with the former is punched out of a single-part plate having a positive temperature coefficient and is shaped in such a manner that the fluxes in the two legs of the current core (1) are uniformly loaded when the resistance of the adjustment loop (6) is changed by means of a slidable contact bridge (9). Due to the symmetric loading of the fluxes in the two legs of the current core (1), the temperature-dependent voltage and current no-load drives are prevented. This is why copper can also be used as a material, the positive temperature coefficient of which increases or decreases the resistance value of the adjusting device with rising or, respectively, falling temperature. This results in a temperature-dependent change in the angle of adjustment so that the temperature-dependent phase-angle error of the meter is reduced.

The flap is movable between limits wherein a forced air is caused to pass through a heat exchanger 3 or by-pass it. Alternatively the actuator 11 may adjust a valve in a heating water pipe. During steady state conditions excess air is vented to atmosphere via a throttle 15, or alternatively, via a solenoid operated valve 24. Alternative pump arrangements are shown in Figs. 2 and 3. Sensor 5 detects external air temperature and optional sensor 7 detects the temperature in air duct 12 downstream of the heat exchanger.
