Abstract: REFUSE CONTAINER WITH SECURITY LOCKING MECHANISM     Abstract of the Disclosure A refuse container incorporating a security locking mechanism disposed completely within the container and which is actuated only when the container is turned over.  In one embodiment a weight is mounted to pivot by gravity through a circular path when the unit is tilted.  A hammer carried by the weight strikes an anvil on a crank arm which operates through a toggle connecting link to pivot a locking lever.          A detent on the locking lever is moved out of engagement with a perimeter frame which is pivotally mounted on the open end of the container.  A closure lid which is independ-ently locked to the frame swings open with the frame for discharging the contents.  In another embodiment a weight is moved by gravity through an arc to strike and pivot a detent arm which normally retains a larger second weight.          The second weight then moves by gravity along a linear path towards the end of a tube where it strikes and pivots a locking lever.  The lever then moves a detent out of engage-ment with a perimeter frame which thereby is free to swing open with the closure lid for dumping the contents.

Abstract: ABSTRACT OF THE DISCLOSURE     A data terminal utilizes a time division multiplexer to monitor traffic on up to 8000 input lines in banks of 1000 lines and converts the information in each bank from parallel to serial form as 1000 serial 112 bit parallel words, records  the various kinds of event count data and usage time duration for each input line, and under interrogation by a control center transmits the accumulated data.      The terminal has up to eight serial synchronously operating memory banks, one for each bank of 1000 lines, each memory bank containing an accumulating memory which counts the events as they occur and a passive memory which upon command receives data from the accumulating memory.  Data in any passive memory may be read out of the terminal on command from a remote supervising unit. Accumulation operation of the terminal is automatic, and data read out and subsequent clearing of the memories is controlled by the remote supervising unit.  The condition of each line is examined continuously cyclically to determine the presence or absence of specifically different particular events and the durations of such events.  The accumulated data is usable directly for billing pur-poses when the apparatus is used to monitor telephone subscriber lines.      A processing verifier generates test signals and processes them through the apparatus to determine the functional accuracy or the apparatus, and generates an alarm when a malfunction is detected.

IPC: G01N21/75
Filed: 1978-06-19
Granted: 1982-01-19
Abstract: Apparatus for measuring progressively the absorbance changes of a large number of aliquots from a plurality of different samples. The sample introduction, testing instructions, aliquot preparation, reagent dispensing, absorbance measuring and data recording all can be accomplished in a continuous mode of processing. Stat and batch operation also can be accomplished. The aliquots are in an array of cuvettes which is advanced slowly along a circular path. Photometer means, preferably having several photometric detectors, are mounted in fixed orientation on a common support that advances rapidly along a similar circular path, such that radiation passing through each of the cuvettes is monitored many times by a specific photometric detector by the time that cuvette completes one circuit of its path. The photometric detectors can operate at several different wavelengths. Many different chemical reactions can be monitored at the same time. The radiant energy passing through each cuvette is received by the continuously moving photometer means, is converted electrically into a digitized value proportional to absorbance and is transmitted digitally from the moving assemblage of photometric detectors, cuvettes and electrical components to a stationary receiver. In one embodiment, the digital transmission is in the form of a pulsed train of light signals. In another embodiment, one or more slip rings transmit electric signals from the moving assemblage to the stationary portion. Suitable drive elements, sample and reagent storage and transfer mechanisms as well as cuvette laundry means may be provided as part of the complete apparatus.

Abstract: TITLE OF INVENTION               A DRUG NEBULIZING SYSTEM FOR MEDICAL VENTILATORS             OF THE VOLUME-LIMITED TYPE     ABSTRACT OF DISCLOSURE An all-pneumatic medical ventilator of the volume-limited type is provided with a pneumatically driven drug nebulizer for injecting medication into the patient's breathing circuit in response to a cyclic pressure signal from the ventilator.  The nebulizer is driven either directly or indirectly, according to the desired mode of use, from the pressurized oxygen source of the ventilator.  In a preferred mode, a given portion of the tidal volume of gas is temporarily withdrawn from the breathing circuit during inhalation and subsequently forcibly returned by way of the nebulizer to the breathing cir-cuit.  This takes place during the same inhalation period so that nebulized medication is added to the patient's breathing circuit without changing either the predetermined oxygen concentration or tidal volume of the breathing gas.

Abstract: Abstract of the Disclosure A photoelectronic smoke detector has walls around a dark chamber to which smoke, but not light, is admitted, and through which light is directed from a source on a path to a limited area of a chamber wall.  A first photocell views light scattered from the through path by particles in the path primarily and also receives background light scattered from the chamber wall outside the limited area.  A second photocell is disposed to receive background light substantially only from the limited area and other areas outside the source light path.  The first cell produces a first signal in response to background and particle-scattered light.  The second cell produces a second signal corresponding to background scatter.  The first and second cells, preferably photovoltaic photodiodes, are coupled in opposition in a circuit whose output consequently is substantially independent of the background light.
