Patent ES-404235-A1 (ES)
Title: Fluid flow control means
IPC: A61M5/168
Filed: 1972-06-24
Abstract: The flow controller repeatedly opens and closes a magnetic check valve for periods of time which determine the flow rate through the valve. The magnetic valve preferably has a movable valve closure member with an elongated stem which extends parallel to the direction of flow of fluid through the check valve. The stem is made of magnetic material. An electro-magnet is placed at the side of the valve, outside of the valve housing. The electro-magnetic field pulls the valve stem laterally to tip the valve member and open the valve. When the magnet is de-energized, the valve member moves back to its seat. The controller is used to control the flow of parenteral fluids into the veins of a human patient. The parenteral fluid controller has a drip chamber for collecting drops of fluid falling from a reservoir. The magnetic check valve is located in the conduit between the drip chamber and the patient's vein. A drop detector is provided for producing a signal each time a drop is formed. The latter signal controls the opening and closing of the valve and thus controls the flow of the parenteral fluid. Safety features are provided whereby the valve closes automatically if a drop has not been detected for a pre-determined length of time. Therefore, abnormalities in the operation of the system will not cause excessive flow of Fluid or infusion of air into the patient's veins. An attendant will be warned of such a condition, or if the flow rate is too low or too high, or if the fluid level in the reservoir is low.

Title: Electronic security system
IPC: G08B13/24
Filed: 1974-08-28
Abstract: An electronic security system especially adapted for use in retail stores and employing a multi-frequency resonant tag circuit having distinct frequencies for detection and deactivation. A transmitting system provides an electromagnetic field within a controlled area at a frequency which is swept through a range including the detection frequency of the resonant circuit. In the presence of a tag circuit within the controlled area and operative at the detection frequency, pulses are detected by a receiver which includes noise rejection circuitry for discriminating true signals from noise. The receipt of a predetermined number of signal pulses within a prescribed interval of time causes an alarm actuation. The resonant circuit is formed by printed circuit techniques as a relatively small tag which can be affixed to an article of merchandise. The tag includes a fusible link integrally formed as part of the circuit and which can be fused upon application of an electromagnetic field of predetermined magnitude at the deactivation frequency of the resonant circuit. Deactivation of the tag destroys the resonant properties of the tag at the detection frequency such that a deactivated tag produces no alarm when passing through a controlled area.

Title: Leaner gauge for narrow neck containers
IPC: G01B5/20
Filed: 1982-06-23
Abstract: In the inspection of generally round glass containers where the containers are indexed into the gauging stations or positions by the movement of a starwheel mechanism, the containers are held in a generally upright attitude with their bottoms engaging a pair of spaced rollers extending through a slide plate at the gauging station. Each roller is biased in an upward direction against the container bottom. The containers are rotated, in station, by engagement of the sidewall thereof by a rotating wheel mounted on an axis that is somewhat out-of-vertical to aid in holding the container down against the rollers and slide plate. The gauging rollers each have their vertical movements drive the core of a separate differential transformer. The output of the transformers are amplified, alegebraically summed and fed to a discriminator. The tracking of the rollers is such that the output signals from the discriminator are a reflection of the relative positions of the rollers and the output is fed to a reject mechanism or indicator when a predetermined difference indicates that a "leaner" container is being gauged.
