Abstract: ABSTRACT        The present invention is directed to a container device having multiple seals, and particularly to a container device of the type described which provides an initial high security seal and which is preferably subject to reclosing after initial opening.  The device in its broadest sense is characterized in the provision of a container 10 having a flange 17 projecting laterally therefrom.  A cap 12 is mounted in the mouth of the container, the cap having a further flange 23 in coplanar alignment with the flange of the container.  A membrane 13 is disposed in covering relation of the container and flanges and a pair of continuous concentric seals S, S' are formed between the membrane and the flanges.  After opening of the container by removal of the membrane, the cap may be replaced to provide a temporary reclosure.  In accordance with various embodiments, the first mentioned structure may in turn be mounted in an additional surrounding container, itself having a flange 118, in which case a third seal is effected between the membrane and the flange of the outermost container.  In accordance with a further embodiment, the cap member 212 may include a central raised table portion 227 which is coplanar with the flanges, with a further seal being effected between the membrane and the table.  Desirably the membrane may incorporate indicia and the device may be constructed and arranged such that when the membrane is removed to open the container, the indicia containing components remain fixed to the table.

Abstract: ABSTRACT Apparatus for determining the level of fluid in an opaque vessel is described.  An impulse device is arranged to impart mechanical vibrations to the vessel wall.  These vibrations are picked up as they decay by a transducer. The vibrations are more seriously damped when there is more rather than less fluid in the vessel and this is used as the basis for obtaining the fluid level. The transducer converts the mechanical vibrations to electrical oscillations which are processed to determine the frequency content and, possibly also for greater accuracy, the amplitude content.  In general the lower the frequency the higher the fluid level.  The apparatus may be provided in a fixture on which the vessel is supported or may be provided in the form of n hand carried pistol which can be applied to any part of the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE   A system for the measurement of temperatures in a reactor such as those operated under high pressure and/or temperature is disclosed.  The tem-perature is measured by the use of a pyrometer which is in optical communica-tion with a measuring duct which can be disposed in the wall of the reactor and is in optical communication with the reactor interior.  The measuring duct comprises two concentric tubes the outer one of which extends beyond the inner tube in the direction of the reactor interior and has a conical constriction immediately following the termination of the inner tube.  The concentric tubes are provided with a common end section such as in the form of a cone in the direction of the reactor exterior.  A hermetic housing defining a safety chamber is disposed exteriorly  thereof the hermetic housing having two opposed pressure and heat resistant windows in alignment with the inner tube and the pyrometer.  The hermetic housing is not, however, permanently attached to the measuring duct.  Means are provided to mount the measuring duct against an exterior wall of a reactor.  Means are also disclosed to maintain the windows free of condensation, carbon deposits, etc. and to insure the contin-uous measurement of the temperature within such reactor.

Abstract: TITLE          Friction Interface Unit For A Clutch And A Brake ABSTRACT OF THE DISCLOSURE    A friction interface unit is shown according to the teachings of the present invention for use with a clutch, a brake, or a clutch-brake.  The unit includes a hub having an annular friction flange and adapted to receive a shaft.          A first housing portion is rotatably supported by a pair of bearings interposed between and in radial alignment with the hub and the first housing portion.  The first housing portion is adapted to be associated with a sheave, an anchor mount for a brake, or a ring disc for a caliper brake.  A second housing portion is further provided which has a cen-tral circular portion and which is bolted to the first housing portion thereby forming a full housing.  Also included is a piston having an annular flange extended over said central circular portion to form a cylinder with a single O-ring.  The second housing portion has a rotary air union mounted thereon for introducing fluid pressure into the cylinder to activate the piston to cause a friction facing mounted thereon to engage the friction flange for rotation of the hub.  In operation, i.e., engagement, the entire unit rotates and when rotating there is no relative motion between the races of the bearings thus measurably increasing bearing life.

Abstract: ABSTRACT    A separate Detector Module and Printer Module are provided.  The Printer Module is incorporated in an attache case and has space so that the Detector Module may be carried in the case.  A power connection is provided in the case for the Detector Module and a communications connection to the Printer is also provided.  The power connection to the Detector is via a separate power cord distinct from the power cord to the Printer.  Thus the Detector may be monitoring one power line while the Printer is plugged in to another. The plugs on the ends of the power cords to the Printer and to the Detector have both male and female connectors piggy-back so that they may be plugged in to the same power line outlet or the Detector may be plugged in to a power line outlet and the machine to which the power is monitored may be plugged in piggy-back with the detector.     The Detector Module derives a synchronization signal from the the half-wave crossovers of the AC power line.  A half-wave peak detector detects the peak voltage of each half wave.  An impulse detector detects the voltage of any impulses occurring during a half-wave.  A common mode detector detects the peak value of each half-wave across the common mode terminals.  A microcomputer is provided together with a clock/calendar for recording threshold values and for each half-cycle if a SAG or SURGE is detected; the time that the SAG or SURGE was initiated; the voltage of the half cycle of greatest SAG or SURGE during the event and the number of cycles is recorded.  For LO and HI AVERAGE an average register stores the average of the peak values for each of the last thirty-two half cycles and that average is compared with the threshold to determine if an event has occurred.  If an event has occurred, the duration and the lowest average occurring during the event is stored.  The time an impulse occurs is recorded to the nearest second along with the voltage of the peak impulse during the half cycle of the event is stored.  For COMMON mode the value of the worst half cycle occurring during any event is recorded along with the number of cycles during which the COMMON mode occurs.  BLACKOUT time OFF and time ON are recorded.    Except for BLACKOUT, the worst ten of each of the above events are stored and the last ten events that occurred are stored.  For BLACKOUT the last five OFF and five ON events are stored.  For each of the above the number of events that have occurred is stored.    Other novel features include memory check after battery backup; the method of setting thresholds, monitor ID and the clock/calendar without the use of a full numeric keyboard or an ON LINE display; an event defeat switch on the Detector; a clear event light switch on the Detector; two battery off switches  on  the  Detector  to prevent  accidental  loss of memory; novel IMPULSE and COMMON mode detectors.

A readout unit can be actuated in accordance with the information sensed at the surface of the earth to give a visual indication or other output representative of or dependent upon the downhole information.
