Abstract: This disclosure is of a mask-free device for supplying sufficient gas to a medical patient and for more accurately sampling the exhalation gas of the patient. The device includes a flexible body having lumens adapted to extend into the nares of a patient and adjacent the patient's mouth for collecting and transmitting a sampling of the patient's end tidal exhalation to a gas analyzer to analyze one or more component gases in that exhalation. The disclosure also discloses the transmittal of pressure from the nares of the patient to a pressure transducer for determining the respiratory phase of the patient and for controlling the volume of oxygen delivered to the patient. The body of the mask-free unit further includes conduits for delivering oxygen through diffuser orifices to positions adjacent the patient's nares and mouth.

Abstract: Disclosed are various methods and devices for facilitating medical and/or procedures that are performed without “general anesthesia,” which is also described in the specification as the state of patient “unconsciousness” resulting from a drug administered by an anesthetist or anesthesiologist. The devices safely and effectively provide and maintain drug infusions that do not push the patient into unconsciousness and/or general anesthesia. Devices according to embodiments of the invention include the use of stored parameters and/or values that correlate to drug delivery during a procedure, and a patient health monitor to measure and send signals regarding a patient health condition to a processor or other computational device.

Abstract: A portable high speed, low cost, wide spectrum light scanning unit with an aiming device for receiving reflected light from an object and diffracting the light into segments of wavelengths and a linear sensor array having elements positioned to receive the segments and to measure the relative magnitude of such segments to define a spectral distribution of the object for transmission to a remote site for identification and/or analysis without augmentation. In addition, the specification discloses the use of a micro-controller to process the distribution and to identify and/or analyze the object.

Abstract: A high speed, low cost, apparatus and method of identification, examination of objects and quality control of manufactured parts and sheet materials, the apparatus including a comparator having memory storage of data representative of the surface of a first “standard” spatial linear distribution of light and memory storage of data representative of another portion of the surface, and including an algorithm for comparing data of the standard with data representative of the second spatial linear distribution of light reflected from a surface to determine if there is a correlation between the two spatial distributions.

Abstract: Disclosed are methods for facilitating medical and/or procedures that are performed without “general anesthesia,” which is also described in the specification as the state of patient “unconsciousness” resulting from a drug administered by an anesthetist or anesthesiologist. The methods safely and effectively provide and maintain drug infusions that do not push the patient into unconsciousness and/or general anesthesia. Methods according to certain embodiments of the invention include the use of parameters and/or values that correlate to drug delivery during a procedure, and a patient health monitor to measure and send signals regarding a patient health condition to a processor.

Abstract: A high speed, low cost, wide spectrum light scanning and sensor unit (10) for receiving reflected light from an object and diffracting the light into segments of wavelengths and a linear sensor array (32) having elements positioned to receive the segments and to measure the relative magnitude of such segments to define a spectral distribution of the object together with a digital identifier-controller (36) connected to said sensing device and having a memory for memorizing a spectral distribution of light representing a first standard object, and additional memory for receiving a spectral distributions of other objects and programmable logic circuitry containing a program for determining the similarity between the standard object and the other objects.

Abstract: An apparatus and method for preventing contamination of the Post Anesthesia Care Unit of A Hospital by the use of a mask sealed to the patient's face and connected by a ventilator circuit to an airator that pulls a vacuum to exhaust the patient's expirations to the outside atmosphere. The disclosure also includes a "oxyvent" which is a tube adapted to be attached to an oxygen tank and to a patient to provide a higher oxygen ratio to the patient and to provide forced ventilation to a patient who has difficulty ventilating.

Abstract: Abstract A method for stabilizing the upper layers of the earth's surface is claimed that comprises the steps of: mixing an amount of lime with an amount of water, simultaneously or sequentially mixing an amount of fly ash with the lime/water mix to form a slurry, distributing said slurry onto the earth's surface and working said slurry into the upper layers of the earth's surface.

Abstract: A seal for high pressure, large diameter applications wherein three factors, each individually known in the prior art, are combined to provide a seal which is capable of operating in such applications. These factors are (1) a ratio of face width to the inner radius of the face in the range of 0.085 to 0.30; (2) hydrodynamic lift-off pads; and (3) controlled negative rotation of the sealing rings.

Abstract: A symmetrical package seal containing two balanced end face seals, the stationary components being adapted for use with shafts of different sizes. In addition, the package seal has means for centering the rotating components relative to the stationary components, for aligning the sealing faces parallel contact, and for bleeding fluid from the chamber formed by the end face seals.

Abstract: This specification discloses a dual seal combination for sealing the space between a housing and a shaft which passes through the housing. The combination is formed of an inboard seal and an outboard seal which are axially spaced from one another to define a buffer zone containing a buffer fluid. The inboard seal has radial faces provided with pumping grooves for sealing high pressure and for pumping buffer fluid from the buffer zone towards the upstream or high pressure side of the seal to lubricate the seal faces and to insure against leakage of fluid.

Abstract: A variable ratio belt drive of the type in which each pulley has an axially movable pulley half for varying the effective drive diameter and speed ratio in a continuous, stepless manner. The drive includes a primary control assembly in one pulley having a threaded interconnection between the drive shaft and one of the pulley halves for effecting a change in the drive diameter upon application of a brake band to a collar mounting the pulley half. In one preferred embodiment, two collars and two brake bands are provided while in another, only a single band and collar is used. The other pulley is provided with a secondary control assembly which automatically responds to the primary control assembly and preferably includes cam means for precluding belt slippage.

Abstract: This invention is directed to a low energy tandem seal which includes an end face seal cooperatively interconnected to a dynamic seal for sealing the circumferential space between a housing and a shaft. Under static non-operating conditions, the end face seal precludes fluid loss from the housing. Upon rotation of the shaft, the low energy dynamic seal provides fluid pressure which opposes loss of fluid from the housing and which disengages the end face seal to avoid a loss of energy and to reduce wear.

Abstract: This specification discloses a Dual Surface Lapping Machine having at least one fixed lower spindle and an upper spindle carried by an A-frame mounted on guide ways. The spindles and guide ways are parallel to one another to permit accurate lapping of piece parts and to facilitate dressing of the lapping surfaces. The upper spindle is mounted in self aligning bearing means which permits floating movement of the upper lapping surface upon work pieces of different thicknesses. To provide accurate dressing of the lapping surfaces locking means are provided to lock the self-aligning bearing. Each spindle is adapted to receive a dressing tool so as to accommodate accurate dressing of the surfaces in a manner eliminating bending deflections associated with prior art devices.
