Abstract: ABSTRACT OF THE DISCLOSURE     A fire and explosion detection system for discriminating between radiation produced by a source of fire or explosion to be detected and radiation produced by a source of fire or explosion not to be detected, comprises two radiation detectors respectively responsive to the intensity of radiation in different wavelength bands to produce respective electrical outputs.  One detector responds to a wavelength band including 4.4 microns (to detect hydrocarbon fires).          In one embodiment, the latter band is relatively narrow and included by the band to which the other detector responds which is relatively broad.  In another embodiment, the bands of both detectors are relatively narrow.  A rate of rise unit and a threshold unit responsive to the first detector produce signals of one type when the rate of rise of, and the value of, the intensity of the radiation received by that detector exceed predetermined values.  A ratio unit measures the ratio of the intensities of the radiation respectively received by the two detectors and produces a signal of the opposite type when the ratio indicates that the source of radiation is a fire or explosion to which the system is not to respond.  An AND gate produces a fire and explosion indicating output only when the signals of the first type exist in the absence of the signal of the opposite type.

Title: Method and apparatus for filling containers with  liquid
Inventor: EISENBERG BERNARD C
IPC: B67C3/04
Filed: 1981-03-05
Granted: 1983-08-30
Abstract: ABSTRACT         Equally spaced pusher bars moving continuously around a closed path individually engage open top containers and push them in single file through a filling region where they are filled with liquid flowing freely in a continuous sheet from an elongated discharge edge extending along the path above the open tops of the containers.  A separate de-flecting unit is adjustably attached to each pusher bar, each deflecting unit having an upwardly convex wedge-shaped de-flecting surface.  The deflecting units move with the con-tainers through the filling region, and the deflecting sur-faces divide the continuous sheet of flowing liquid into a number of separate streams directed into the interiors of the respective containers, thereby preventing the liquid from contacting the external surfaces of the containers.

Abstract: "Apparatus for, and a Method of, Signalling within a Borehole while Drilling"               ABSTRACT OF THE DISCLOSURE           A telemetry sub for a drill string comprises upper and lower portions electrically insulated from one another by an insulator.  The sub incorporates a transformer having its secondary connected between the upper portion and the lower portion.  In operation a measurement data signal in the form of pulses is supplied to the primary of the transformer by suitable electronic circuitry and a pulsating current signal is thereby induced in the secondary.  This pulsating signal is passed along the drill string towards the surface, a return path for the signal being provided by the earth formations through which the borehole is drilled.  The signal is passed to a receiving station on the surface either directly or by way of one or more repeater subs of the same general construction as the aforementioned sub.  Such a system is capable of transmitting signals at a high rate and with an acceptable signal-to-noise ratio.  Furthermore the subs are relatively inexpensive to produce so that a large number of repeater subs may be distributed along the drill string if desired.

Abstract: ABSTRACT The present invention is an apparatus for monitoring toner concen-tration on a photoreceptor surface. The apparatus includes a light emitting diode, the phototransistor, a beam splitter, and a lens disposed between the beam splitter and the photoreceptor surface to collimate the light beam between the lens and the photoreceptor surface. A portion of the light emitted from the LED is transmitted through the beam splitter and the lens to the photoreceptor surface. Collimated light is reflected from the photoreceptor surface back through the lens and reflected from the beam splitter to the phototransistor. The output signal from the phototransistor because of the incident and reflected collimated light is independent of the distance of the lens from the photoreceptor surface. Alternately, a second lens is disposed between the beam splitter and the phototransistor to enhance overall resolution.

Abstract: Kobelt 34 c/w SELF-ALIGNING SWIVEL ASSEMBLY FOR PUSH-PULL       CABLE CONTROL LEVER ASSEMBLY     ABSTRACT OF THE DISCLOSURE                  A control lever assembly for actuating a control cable, particularly a cable of the type capable of transmitting compressive forces as well as tensile forces, known as a push-pull cable. The assembly has a lever journalled for rotation relative to a body thereof, and a core anchoring structure adapted to rotate with the lever and to be subjected to relative lateral movement during such rotation. The core anchoring means anchors one end of a core of the control cable, and a sheath retaining means retains a portion of a sheath of the cable to restrict axial movement of the sheath following actuation of the cable. A connecting structure, which is struc-turally independent of the control cable, cooperates with the sheath retaining structure and the core anchoring structure to swivel the sheath retaining structure in response to rotation of the core anchoring structure. Thus, the sheath retaining structure swivels to accomodate the lateral movement of the core anchoring structure to maintain approximate alignment of the sheath with the core so as to reduce a tendency of the core to buckle under compressive loads.

Abstract: COMPUTER-BASED SYSTEM FOR      ACQUISITION OF NUCLEAR WELL LOG DATA Abstract of the Disclosure A computer-based well logging system is disclosed, for acquiring nuclear well log data, including gamma ray energy spectrum and neutron population decay rate data, and providing a real-time presentation of the data on an operator's display based on a traversal by a downhole instrument of a prescribed borehole depth interval.          For acquiring energy spectrum data, the system has a multichannel analyzer including a pulse height analyzer and a memory.  After a spectral gamma ray pulse signal coming from a downhole instrument over a logging cable is amplified and conditioned, the pulse height analyzer converts the pulse height into a digital code by peak detection, sample-and-hold action, and analog-to-digital conversion.  The digital code defines the address of a memory location, or channel, corre-sponding to a particular gamma ray energy and having a count value to be incremented.  After a period time, the memory channels contain a spectrum of counts per incremental energy band.  The spectrum data is then accessed by the system central processing unit (CPU) for analysis, and routed to the operator's display for presentation as a plot of relative gamma ray emissions activity versus energy level.          For acquiring neutron decay rate data, the system has a multichannel scaling unit including a memory and a memory address generator.  After a burst of neutrons down hole, thermal and epithermal neutron detector pulses build up and die away.          Using the neutron source trigger as an initializing reference, the address generator produces a sequence of memory address codes, each code addressing the memory for a prescribed period of time, so as to define a series of time slots.  A detector pulse signal produced during a time slot results in the incrementing of the count value in an address memory location.  The process is repeated for every trigger, resulting in the production of time histogram data.  The data is accessed by the CPU and routed to the operator's display.
