Abstract: ABSTRACT        A process and apparatus for manufacturing a synthetic resin hose with a reinforcing member embedded therein consists of initially forming a reinforcing member consisting of a warp tubular member and a braided member.  The warp tubular member is formed by guiding a plurality of warps with a bonding-agent applied thereto through yarn guide holes pro-vided circularly with respect to the outer peripheral surface of a hollow cylindrical member.  These warps are drawn in the longitudinal axial direction of a hose being formed. The braided member is formed by braiding yarns on the outer peripheral surface of the warp tubular member.  The rein-forcing member is then heated for bonding the warps to the braided yarns at the contacts between them to heat set the reinforcing member. A synthetic resin material is coated on the inner and outer surfaces of the reinforcing member by a resin applying device.  The resulting composite body is then cooled and drawn and taken up on a winding mechanism.

Abstract: A B S T R A C T           A method and an apparatus for improving the strength of a soft viscous ground are disclosed.  For improving the strength of an area of some extent, hardenable liquid consisting essentially of cement milk is injected into each one of a plurality of preselected points for promoting dehydration and compaction of the ground.  The liquid is hardened in a short time for forming a rigid tree-like structure.  A measure or index for the local ground strength is obtained at first by using a measuring/injection device, and the injection pressure is set to be slightly larger than the measure or index so obtained.  The liquid may then be permeated into the soft viscous ground at substantially the same injection pressure until the ground is consolidated satis-factorily.

Abstract: PULSED NEUTRON POROSITY LOGGING METHOD AND       APPARATUS USING DUAL DETECTORS           Abstract of the Disclosure.  A source of fast neutrons and two differently spaced detectors are utilized in a well logging instrument, each of such detectors being responsive to the thermal neutron population decay rate.  The inverse of this decay rate is proportional to the measured macroscopic absorption cross section (Sigma).  The measured Sigma is obtained simul-taneously as a function of the radiation detected by each of two detectors.  The signal generated which is indicative of the Sigma observed from one detector is subtracted from the Sigma observed by the second detector.  The difference between the measured Sigma from two differently spaced detectors provides a unique function of the fluid-filled porosity of the formations giving rise to the measured Sigma values.     -1a-

Abstract: Case 2584 ABSTRACT OF THE DISCLOSURE          The apparatus for injecting permanent lubrication has a hopper for holding the lubricating material, and directly beneath the hopper a horizontally disposed screw feeder feeds the material directly to a nozzle assembly.  The nozzle assembly has a valve which in one position directly couples the output of the screw feeder to an injection chamber and in another position couples the injection chamber to the nozzle.  The path which the lubricating material must traverse is thus relatively short and the cross-sectional area of the path may be kept relatively large.  It is well known that oil tends to separate from the fibrous part of the lubricating material if the path is long or the pressure excessive.  The direct coupling of the feed to the nozzle assembly thus reduces the tendency for the oil to separate and enables a simpler machine design to be made.  Also, the lubricating material is injected into the bearing cavity of an end shield directly over the wick in the bearing cavity so that the wick serves to direct the material to both sides of the bearing cavity ensuring good contact between lubricating material and wick.

Abstract: INTEGRAL COMPOSITE NOZZLE-SHIELD ASSEMBLY FOR A GAS-COOLED DYNAMOELECTRIC MACHINE Abstract of the Disclosure An integral nozzle-shield assembly for a gas-cooled dynamo-electric machine such as a large turbine-driven generator is described.          The nozzle-shield assembly is formed of a non-conductive, non-magnetic material such as molded fiberglass and resin and serves to channel hydrogen gas between a heat exchanger and a rotor-mounted fan used to pump the gas through coolant passages in the dynamoelectric machine, and the assembly also provides a labyrinth seal over the fan blade tips. In one embodiment, the nozzle-shield assembly includes two 180-degree halves whose thickness varies circumferentially and which may be installed in a generator by bolting their outer edges to a stator frame member of the generator and bolting the halves together at the two radial joints between halves using flat metal plate connectors. Use of a material such as fiberglass and resin to form an integral nozzle-shield assembly results in a structure which is not susceptible to eddy current losses or damage due to arcing, and this integral assembly is readily  fabricated and easy to install in a dynamoelectric machine.

Abstract: LOW POLLUTION INCINERATION OF SOLID WASTE          Abstract of the Disclosure An incinerator system and method wherein pieces of solid waste, such as fragments of wood, are conveyed in such a fashion as to become disposed within a fluidized bed of an incinerator vessel.  Preferably the solid waste particles are caused to be somewhat homogeneously dispersed within the fluidized bed.  The solid waste particles may be "pre-dried" or moisture may be added to the particles prior to deposition in the fluidized bed for optimum results, depending upon circumstances.  In one embodiment, the fluidized bed is situated above an air delivery chamber at the bottom of the vessel and supports combustion of the solid waste particles in the fine granular material comprising the fluidized bed. The fine granular material is supported by a perforated plate. The air delivery system channels high temperture air into and up through the fluidized bed until operating temperature is reached and so channels ambient air thereafter.  Volatile matter given off by combustion of the solid waste particles in the fluidized bed is burned smokelessly in the vapor space immediately above the bed.

Abstract: RCA 73,331 ABSTRACT OF THE INVENTION A circuit is provided for protecting an amplifier from signal overload upon the application of strong signals at the input to the amplifier.  A unidirectionally conducting semiconductor device and a capacitor are serially coupled between the input to the amplifier and ground.  Means for maintaining a constant voltage is coupled to the junction of the semiconductor device and the capacitor.  Upon the application of a strong signal at the input to the amplifier, the semiconductor device conducts current to the junction of the constant voltage means and the capacitor, causing the voltage across the capacitor to increase.  The constant voltage means senses this voltage increase, and responds by opposing the voltage increase so as to maintain a substantially constant voltage across the capacitor.  The constant voltage at the junction of the semiconductor device and the capacitor maintains the semi-conductor device in a low impedance state, thereby attenuating  the strong signal at the input to the amplifier. The circuit may also be operated in a second mode, in which current conduction by the semiconductor device and constant voltage means is under the control of the AGC system to attentuate the input signal to an I.F. amplifier.
