Abstract: LOCKING SENSOR FOR BELT RETRACTOR     Abstract of the Disclosure:  An emergency locking retractor system for storing a length of safety belt incorporates a sensor which includes a multi-directional pendulum device displaceable from its rest position by acceleration.          Displacement of the pendulum is utilized to change the strength of an energy field imposed upon an electrical signal means.  The output signal of the signal means responds to the change in the energy field imposed thereon and the changed signal is employed to activate solenoid switches which lock the retractor.  The energy field source may be a magnet or a light source and the signal means then may include, respectively, a Hall device or a phototransistor.          Movement of the pendulum from its rest position is utilized to move the magnet closer to or further from the Hall device, or to interpose a shield between the light source and the phototransistor, or to change the position of a reflector used to reflect light from the light source onto the phototransistor.  The resultant change in output signal is employed to close a circuit which connects a power source to the locking medium.

Abstract: BEHIND CASING WATER VOLUME FLOW RATE MEASUREMENT USING CONCENTRIC GAMMA RAY DETECTORS                   (D#74,517-1-F) ABSTRACT OF THE DISCLOSURE         Measurement of the distance from a gamma ray detector to a gamma ray source for location of a channel of undeisred behind casing water flow in a producing well is provided.  Coaxially aligned dual cylindrical gamma ray detector crystals are used at one or more longitudinally spaced locations in the borehole to detect the characteristic gamma rays from the decay of radioactive nitrogen 16 pro-duced by the activation of elemental oxygen nuclei comprising the molecular structure of undesired water flow.  The ratio of counts at the outer coaxial detector to those at the inner coaxial detector is then interpreted in terms of R, the dis-tance from the detector to the water flow channel.  This dis-tance information may then be combined with the linear flow velocity of such undesired water flow to derive an indication of the volume flow rate V of such flow.

Abstract: Abstract of the Disclosure A method of surface planarizing large scale integrated devices, including a double metal lift-off step is described.  A first resist layer is deposited on an insulating layer which is formed over a first metal layer with a pattern structure.  The resist layer is then masked by another metal layer.  Then, a second resist layer is deposited over the metal masking, and is exposed and developed to delineate via holes therein.  The metal masking, first resist layer and insulating layer are successively etched to define the via holes.  During this procedure the second  esist layer is automatically removed.  A second metal layer is then deposited on the metal masking layer and in the defined via holes.  The first resist layer is then lifted off which in turn accomplishes the double metal lift-off of the metal masking and the second metal layer.          Subsequently, a third conductive metal pattern layer may, if desired, be deposited over the insulating layer and the metal filled via holes therein.  A third resist layer is then deposited on the third metal layer and is exposed and develop-ed to delineate a conductive pattern on the resist layer.  The third resist layer is then exposed and developed and then the conductive pattern is formed on the planar surface of the device by lift-off reactive ion etching or other convention-al techniques.

Abstract: ABSTRACT     A fusion power generating device is disclosed having a small, inexpensive core region which may be contained within an energy absorbing blanket region.  The fusion power core region contains apparatus of the toroidal type for confining a high density plasma.  The fusion power core is removable from the blanket region and may be disposed and/or recycled for subsequent use within the same blanket region.  Thermo-nuclear ignition of the plasma is obtained by feeding neutral fusible gas into the plasma in a controlled manner such that charged particle heating produced by the fusion reaction is utilized to boot-strap the device to a region of high tempera-tures and high densities wherein charged particle heating is sufficient to overcome radiation and thermal conductivity losses.  A series of disposable and replaceable central core regions are disclosed for a large-scale economical electrical power generating plant,

Abstract: ABSTRACT OF THE DISCLOSURE           The rabbles of this invention have a concave active face.  They are used in a system for processing material including, for example, a substantially circular and horizontal floor, and a rabble system disposed above, but adjacent to, said floor.  The rabble system urges material on the floor to desired locations, such as discharge openings, in response to relative motion between the floor and the rabble system.  The rabble system includes a plurality of rabbles.  Substantially each rabble has a body portion which carries a curved or angled surface.  Each rabble also has a leading edge.  Said rabbles are preferably oriented in a system with their leading edges at an angle in the range of about 0° to about +13° to the flow of material and with their concave active faces oriented to intercept and move material in the desired direction.  During relative rotary motion between the floor and the rabbles, this orientation and configuration of the rabbles reduces the build-up and bridging of material in front of and between the leading edges of the rabbles while the concave active faces cause substantial amounts of material to flow across the floor.  These rabbles and systems are especially useful in the operation of rotary hearths.

Abstract: APPARATUS FOR CONTROLLING THE AIR-FUEL RATIO       IN AN INTERNAL COMBUSTION ENGINE Abstract of the Disclosure Apparatus for controlling the air fuel ratio in an in-ternal combustion engine to substantially maintain the ratio at a predetermined value while the engine is operating under various load conditions.  The engine has a carburetor with an air passage-way through which air is drawn into the engine.  Fuel is supplied to the carburetor through a fuel system and mixed with air passing through the carburetor.  The carburetor has a conduit through which air is introduced into the fuel system and the engine further has a chamber for combustion of the resulting air-fuel mixture and combustion products are exhausted.  The apparatus comprises an air metering unit fox metering the quantity of air introduced into the fuel system through the conduit to control the air-fuel ratio of the mixture.  The presence of oxygen in the combustion products, which is a function of the air-fuel ratio of the mixture, is sensed and a first electrical signal representative of the oxygen content is supplied.  The first electrical signal is compared with a prede-termined reference level which is a function of the predetermined value to produce a second electrical signal having first and second signal elements, a first signal element being produced when the air-fuel ratio of the mixture is greater than the predetermined level and a second signal element being produced when the ratio is less than the level.  A control responsive to the second electrical signal supplies to the air metering unit a control signal by which the quantity of air introduced into the conduit is controlled.  A change in the control signal is produced whenever the second elec-trical signal has a transition from one signal element to the other thereby for the air metering unit to change the quantity of air introduced into the conduit by an amount necessary to substan-tially maintain the air-fuel ratio at the predetermined value,

ABSTRACT:           Command signal generator for a channel selection device in a mobile receiver for frequency or phase modula-tion which is mobile relative to fixed transmitter stations transmitting at mutually different frequencies.  It is con-nected to the output of the frequency discriminator of the receiver and comprises means for forming a logic signal which indicates the presence or absence of noise, a gate which transmits the clockpulses when a logic signal indi-cates the presence of noise, means for counting the trans-mitted clockpulses and for supplying a command signal for controlling a channel selection device, either which dur-ing a sequence of n time intervals ? a number of pulses counted during each time intervals ? attains a first threshold, or when the number of pulses counted during a time interval ? attains a second threshold which is higher than the first threshold.  Noise pulses are used for generating a command signal for controlling the automatic selection of the frequency by making itself independent to a large extent of the speed of the mobile body.
