Title: Eddy current-type devices for automatically controlling gear changes on vehicles
IPC: F16H63/02
Filed: 1965-03-26
Abstract: Automatic shifts in a stepped transmission 30 of a motor vehicle in response to vehicle speed and engine accelerator depression, with synchronization by engine speed control, are controlled by a device wherein rotation, at a speed proportional to vehicle speed, of a permanent magnet 7 in a coaxial cup 12 on a shaft 13 generates eddy currents in the cup which apply a torque thereto to turn the shaft 13 against a spiral spring 14 to successively engage arms 15 with respective contacts 16 to initiate ratio changes, the magnet 7 being axially movable on a ball spline relative to the cup 12 by the engine accelerator pedal linkage acting at F to reduce the eddy current strength as the pedal is depressed. When an arm 15 engages its contact 16, a magnet associated therewith tends to retain the arm, in opposition to spring 14, so that downshifts will occur at lower speeds than the corresponding upshifts. Each arm 15 remains on its contact 16 while higher gears are engaged. For synchronizing shifts by controlling engine speed during shifts, vehicle and engine speeds are compared by a pair of cups 19, 21 secured on a common shaft 20 biased to a neutral position by a spiral spring 26, a permanent magnet 6 being rotated in the cup 19 at a speed proportional to vehicle speed, and a permanent magnet 22 being rotated in the opposite sense at a speed proportional to engine speed. The axial position of the ball-splined magnet 22 is set in accordance with the gear ratio to be engaged in the transmission 30. During shifts, with coincidental clutch actuation by means not described, this device acts to synchronize the new ratio. If the engine runs too fast, the torque on cup 21 predominates, and an arm 27 on shaft 20 is moved away from a fixed contact 28 to reduce engine speed, while if the engine speed is too low, the torque on cup 19 predominates, causing the engine to be speeded up. Clutch control may be as described in Specification 1,105,781, and automatic double-declutching by unspecified means may be provided. In a modification, the cups 12, 21 may be axially movable instead of the magnets 7, 22.

Title: Production of high structure furnace carbon black
IPC: C09C1/50
Filed: 1965-05-06
Abstract: <PICT:1108241/C1/1> Modified furnace carbon black having high structure characteristics is produced from normally liquid hydrocarbon feedstock having a Bureau of Mines Correlation Index (as defined) of at least 95 by introducing a stream of feedstock axially into a carbon black furnace, introducing a separate coaxial stream of a free oxygen containing gas containing at least 33 volume per cent oxygen, in an amount sufficient to supply at least 7.4 S.C.F. of oxygen per U.S. gallon of feedstock, partially burning the feedstock in the furnace under carbon black producing conditions and recovering the carbon black produced. The free oxygen containing gas may be essentially pure oxygen and is introduced into the furnace at a linear velocity of 40 to 250 feet/sec. The process may be carried out in a furnace such as that described in Specification 679,818. This apparatus may however be modified by provision of a hydrocarbon feed assembly slidably extending from outside the furnace into the feed introduction chamber, jacket gas being introduced coaxially with the hydrocarbon feed. As shown in Fig. 5, the furnace is provided with a cylindrical pre-combustion section 14 upstream of, in communication with and axially aligned with the reaction chamber 10. A feed introduction chamber 27 is similarly disposed upstream of the pre-combustion chamber 14. A plenum chamber 28 is sited upstream of the chamber 27, and is closed by a flange plate 29 with a central opening 31 through which a jacket gas conduit 181 extends axially and slidably. The hydrocarbon feed inlet 171 extends axially through the closed and of 181 providing an annular space between 171 and 181. The free oxygen containing gas is introduced via 201 into the annular space. 171 and 181 comprise an integral assembly which can be slid in and out of the chamber 27. The remainder of the furnace is constructed conventionally.

Title: Aggregates of mineral fibers and thermoplastic materials useful particularly as underlayers for structural sheathings for acoustic insulation
IPC: D04H1/4209
Filed: 1968-08-07
Abstract: The production of structural sheathings or facings having an underlayer affixed thereto, to serve as an acoustical insulating structural member, said underlayer being formed by the combination of mineral fibers, particularly glass fibers of relatively long length in interlaced condition, which is permeated with thermoplastic compositions comprising mixtures of one or more elastomers such as natural or artificial latex, and one or more adjuvants for promoting a chemical bond between the mineral fibers and elastomer component. This underlayer is prepared by forming a mat by the deposition of the mineral fibers in successive layers, which is followed by the thorough impregnation of the fibers with an aqueous dispersion of said thermoplastic composition, the withdrawal of the excess of the latter from the impregnated mat, and the drying of the mat and the final heating thereof to attain an effective reticulation of plastic composition amongst the glass fibers before the mat is accumulated on a storage roller. The final production step of gluing of the underlayers to a sheathing or other support is rendered more secure and satisfactory by partially or completely clogging the pores at one or both faces of the underlayer with a special filling layer before the glue is applied thereto. Furthermore, the appearance of the underlayer on its support is improved, especially when the latter is a vinyl plastic, by removing the folds therefrom which are caused by the rolling up of the former on a reel in the course of its preparation. The elimination of these folds is attained by heating the mat immediately prior to its fixing on its support to relieve slightly the binding of the layers of fibers by the thermoplastic material, which gives rise to a re-arrangement of the stratification of fibers adjacent to the surfaces of the underlayer.

Title: Process for producing uranium oxide rich compositions from uranium hexafluoride
IPC: G21C3/62
Filed: 1974-06-17
Abstract: Conversion of gaseous uranium hexafluoride to a uranium dioxide rich composition in the presence of an active flame in a reactor defining a reaction zone is achieved by separately introducing a first gaseous reactant comprising a mixture of uranium hexafluoride and a reducing carrier gas, and a second gaseous reactant comprising an oxygen-containing gas, the reactants being separated by a shielding gas as introduced to the reaction zone. The shielding gas temporarily separates the gaseous reactants and temporarily prevents substantial mixing and reacting of the gaseous reactants. The flame occurring in the reaction zone is maintained away from contact with the inlet introducing the mixture to the reaction zone. After suitable treatment, the uranium dioxide rich composition is capable of being fabricated into bodies of desired configuration for loading into nuclear fuel rods. In another embodiment, an oxygen-containing gas as a third gaseous reactant is introduced when the uranium hexafluoride conversion to the uranium dioxide rich composition is substantially complete. This results in oxidizing the uranium dioxide rich composition to a higher oxide of uranium with conversion of any residual reducing gas to its oxidized form.
