Abstract: A vapor recovery system for a fuel storage tank. The system includes a pair of VOC adsorbent canisters that alternately recover VOC vapors from the fuel tank ullage or are regenerated. Regeneration of the VOC adsorbent canisters is provided by exhausting the VOC vapors from the VOC canisters using a vacuum pump and back into the fuel tank ullage. When the operating pressure of the fuel tank ullage is elevated, an auxiliary VOC adsorbent canister is operated in parallel with the pair of canisters in order to recover the increased amount of VOC vapors in the tank ullage.

Abstract: The disclosed pressure swing adsorption processes can recover helium from source streams of less than about 10 percent by volume helium and concentrate the helium to a concentration of greater than about 98 percent by volume. Two stages of pressure swing adsorption are used in series. The source of the helium gas will be natural gas wells. The source gas will contain hydrocarbons but in most instances the primary gas other than helium will be nitrogen. Each stage of pressure swing adsorption will contain a plurality of adsorbent beds, and preferably about four. In each stage the adsorbent beds will be cycled through multiple phases. In the first stage the adsorbent beds will sequentially undergo the phases of adsorption, recycle, depressurization, evacuation, helium pressurization and recycle feed pressurization.

Abstract: A natural gas feed stream containing significant quantities of nitrogen can be increased to a content of greater than 95 percent by volume of natural gas, and preferably greater than about 98 percent, by passing the natural gas feed stream sequentially through at least four adsorbent beds which are cycled through six phases comprising an adsorption phase to adsorb natural gas, a recycle phase to remove feed gas from the voids in the adsorbent bed and nitrogen from the adsorbent by the passage of a depressurization gas therethrough to produce a recycle gas, a depressurization phase to reduce the adsorbent bed pressure to about ambient and to produce the depressurization gas, an evacuation phase where the pressure in the adsorbent is further reduced and an enriched natural gas product stream recovered, a pressurization phase where the pressure in the adsorbent bed is increased using nitrogen gas from a bed in an adsorption phase, and further pressurizing the adsorbent bed in a recycle feed pressurization phase

The at least seven precordial electrodes extend laterally across the support so as to assume different lateral positions across the human chest when the support is positioned over the chest. Circuitry is carried by the support in electrically connected relation to the electrodes and is capable of selectively operating a selected six of the plurality of precordial electrodes at positions which correspond to the six Wilson precordial leads for the individual. The circuitry is constructed and arranged to convert the electrical heart activity of the individual obtained by the electrodes into a form capable of producing a twelve-lead electrocardiogram.

Abstract: The present invention provides a peak flow meter which facilitates a subject's compliance with the use thereof. In one embodiment, the peak flow meter provides an alarm for indicating that the subject is due for a peak expiratory flow rate evaluation when the subject has failed to use the peak flow meter after a predetermined period of time. In another embodiment, the peak flow meter is provided with circuitry which derives a data result corresponding to the peak expiratory flow rate of air blown into the peak flow meter for a number of blows. A first comparator determines the best data result within the number of blows and a memory stores each best data result. A second comparator compares each best data result to a specified value and provides an enabling signal to an alarm when a best data result is a predetermined amount lower than the specified value.

Abstract: A device for measuring electrical activity of the heart of a user. The portable device includes structure for receiving at least two leads of electrical activity of the heart of the user. This information is amplified, and coupled to a memory to produce audio signals of a form suitable for transmission over telephone lines in response to input signals. These input signals can be either from the memory or from the output of the amplifier, depending on the mode being commanded. A control structure commands the mode of operation. Live mode allows the acquired input to pass directly to the speaker, to be passed over the telephone lines. Recording mode records the input. Time interval mode records the entire capacity of the memory once. Rolling mode continually acquires and displaces other information that was previously in place.

Abstract: A heart monitoring device for use under emergency conditions including a portable housing, a pair of electrodes and a pair of electrical wires connecting the electrodes to the housing and to an electrical circuit carried therein. The electrodes are usable in two modes. One mode is a precordial mode wherein the electrodes are mounted on the exterior of the housing in spaced positions fixed with respect to the housing in commonly outwardly facing relation so as to be conveniently engageable with the skin of the chest of a user by manually engaging the housing and moving it with the electrodes fixed thereto into housing retained operative positions on the chest skin. The second mode is a non-precordial mode wherein the electrodes are removed from the housing and, preferably, self-retained within the armpits.

Abstract: A cardiac monitoring system for monitoring a plurality of patients including a plurality of patient-worn units and one or more office units. A patient unit detects a patient's EKG and analyzes the EKG in real time (during the patient's R-R interval). It provides morphology analysis, heart rate data, ST segment analysis, symptomatic and asymptomatic event recordings, and the counting of ectopic runs. The analyzed data is sent over a standard voice-grade telephone line or other suitable communication channel to an office which prepares a patient report for a physician. In addition, the office unit provides an interactive scheme by which various alarm and recording criteria are established for a particular patient at the time of hook-up. Also, the office unit automatically communicates with the physician under predetermined emergency circumstances so that a patient can get medical attention with a minimun time delay.

Abstract: A portable heart monitoring apparatus incorporating unique structural and functional features. Electrodes carried on the apparatus capture electrical signals representing the functioning of a heart beating therewithin and provides sensible output indications corresponding to predetermined characteristics of the electrical signals and, hence, of the detected heartbeat. One of the sensible outputs provided is the selective actuation of either of two logic lights indicating whether the heartbeat is above or below respectively a predetermined beating rate. The unit is automatically turned on by merely holding the instrument in the user's hand and the selective actuation of the various operational modes may be conveniently made by selectively placing one of the hands's digits (such as the thumb) from one touch contact point to another. Part of the operation in the test mode involves the effective testing of the reserve battery power without actually loading the battery.
