Abstract: ABSTRACT OF THE DISCLOSURE A glass heating method and apparatus, such as a glass melting furnace or a forehearth, utilizing a re-fractory lining and electrically energized heating elect-rodes.  The refractory lining is an erosion resistant material, preferably a chromic oxide refractory, having an electrical resistivity which is less than the re-sistivity of the molten glass, preferably an E glass, which is being heated.  To avoid short-circuiting through the low resistance refractory, the refractory interposed between electrodes of opposite polarity is cooled to a temperature less than the temperature of the molten glass and at which the resistivity of the refractory is materially increased.  Where the electrodes of opposite polarity are carried by opposing side walls, the end and/or side walls of the apparatus are cooled.  Where the electrodes are all carried by a single wall, that wall is cooled.

Title: Cylindrical fibrous structures and method of manufacture
Inventor: PALL DAVID B
IPC: D01D5/08
Filed: 1985-01-04
Granted: 1989-06-20
Abstract: : Cylindrical fibrous structures comprising a fibrous mass of nonwoven, synthetic, polymeric microfibers wherein the microfibers are substantially free of fiber-to-fiber bonding and secured to each other by mechanical entanglement or intertwining, the fiber structure having a substantially constant voids volume over at least a substantial portion of the structure and, preferably, a graded fiber diameter structure, both as measured in the radial direction. The structures are particularly useful as depth filters. The method for preparing such fibrous structures comprises the steps of: (a) extruding synthetic, polymeric material from a fiberizing die and attenuating the extruded polymeric material to form microfibers by the application of one or more gas streams directed toward a rotating mandrel and a forming roll in operative relationship with the mandrel; (b) cooling the synthetic, polymeric microfibers prior to their collection on the mandrel to a temperature below that at which they bond or fuse together, thereby substantially eliminating fiber-to-fiber bonding; and (c) collecting the cooled microfibers on the mandrel as a nonwoven, synthetic fibrous mass while applying a force on the exterior surface of the collected microfibers by the forming roll; wherein the process variables are controlled to form the cylindrical fiber structure with at least the major portion of the fibrous mass having a substantially constant voids volume.

Abstract: Abstract A process for the enhanced oil recovery of under-ground mineral oil deposits, in which one or more sub-stances which are scarcely water- and oil-soluble at de-posit temperature but are well soluble or volatile in the hot flooding medium and whose melting point lies above the deposit temperature, are added to the flooding medium hot water and/or water vapor.  They move with the hot flooding medium through the deposit and precipitate as a solid pre-ferably at that part of the temperature front which is advancing fastest, thereby constricting the pores of the deposit temporarily and reversibly, until the solid is dissolved or evaporated again by the hot flooding medium flowing on after, which has the overall effect of an areal and vertical equalization of the temperature front.

Abstract: ELECTROACOUSTIC NETWORK            ABSTRACT OF THE DISCLOSURE         Disclosed is a passive delay network for insertion in the high frequency signal path of a crossover network in a high fidelity loudspeaker.  The delay network provides a device to adjust the optimum listening window electrically rather than by changes in the physical construction of the speaker cabinet.  Electroacoustic high frequency and low frequency drivers may be mounted in a planar baffle or mounted co-axially.          The delay network retains a "flat" amplitude-frequency charac-teristic and minimizes time dispersion in the acoustic signal received by the listener.  Correction for time delay is most important near the transition frequency of the crossover network because near the transition frequency substantially equal sound energy is radiated by both the high frequency and low frequency drivers.  Also disclosed is a novel construction for a co-axial driver combination and a technique for adjusting both the delay in the electric delay line network and the air path delay of electroacoustic drivers.  The co-axial drivers include sound absorbent material between the drivers to prevent direct sound radiation between the low and high frequency drivers.  The adjustment technique comprises a method of experimentally testing and adjusting the mutual inductances in the electric delay line and the air path delay.

Abstract: ABSTRACT           An excitation arrangement for a long stator drive, particularly a synchronous long stator drive for rapid transit systems having combined generation of propelling and carrying forces comprises at least one heteropolar magnet which has a plurality of channels extending at right angles to the long stator direction and which are open at their pole plane lying opposite the long stator and in which magnetic coils assigned to the conductors are disposed.  In order to improve the dynamic properties of the magnet, a subdivision of the magnetic coils generating the magnetic field is provided. Differing electrical behavior for slow and fast changes in the voltage driving the coil current is achieved by a tight coupling of one of the sub-coils to a short-circuit coil.          Given slow changes in the drive voltage, a magnetic force resulting from the entire coil flux occurs.  Given fast changes in the drive voltage, a dynamic reduction of the effective coil inductance leads to a fast current and magnetic force changes.

Abstract: Abstract of the Disclosure The speed reducing mechanism is of simple construction and is easily adapted for providing different ratios of speed reduction, particularly a high ratio of speed reduction.  The mechanism comprises inner and outer gears in planar engagement and a non-rotatable shifter member.  In alternate embodiments, either the inner gear or the outer ring gear may be rotatable.  In one disclosed embodiment the inner gear is driven by the input shaft under control of the shifter member to engage at its periphery with the ring gear causing the ring gear to be driven thereby.  The inner gear tracks within the ring gear but is maintained non-rotatable by the shifter member.  The gear ratio is a function of the number of teeth externally on the inner gear in comparison with the number of internal teeth on the ring gear.  The closer in number the teeth, the higher the reduction ratio.  In another embodiment the speed reducer is in the form of a hand operated winch.

Abstract: ABSTRACT OF THE DISCLOSURE         A fabric softening built detergent composition, often preferably in the form of a stable and pourable liquid, includes a detersive proportion of a synthetic organic detergent, such as anionic and/or nonionic detergent(s), a building proportion of polyacetal carboxylate builder for the detergent(s) and a fabric softening proportion of bentonite.  The presence of the polyacetal carboxylate builder in the described compositions increases the fabric softening action of the bentonite during washing of laundry.  In preferred liquid detergent compositions the bentonite helps to stabilize such liquids and inhibits separation of tile polyacetal carboxylate builder particles, which are dispersed in the aqueous liquid medium.  Also within the invention are methods of simultaneously washing and softening fabric materials by washing them in wash waters containing the components of the described compositions, and then rinsing and drying.  In further aspects of the invention an antistatic agent, such as dimethyl distearyl ammonium chloride, is present in a fabric softening composition and in the wash water to inhibit the development of electrostatic charges on the washed material and the resulting objectionable clinging of such materials together after drying.

Gripper arms (16) at each of a plurality of insert stations S comprise a first jaw member (24) and a second jaw member (26).  The second jaw member (26) is movable toward and away from a first jaw member (24) to selectively engage articles therebetween.  Field-generating means (420) is mounted on one jaw member while a sensor (400) is connected on the other jaw member.  The signal generated by the sensor (400) is indicative of the flux density of the field created by the generating means (420).  The sensed flux density of the generated field as a function of the relative displacement of the first and second jaw members (24,26).  The signal generated by the sensor (400) is accordingly related to the separation of the first jaw member (24) and second jaw member (26).  If the sensor-generated signal is within predetermined limits of a stored reference signal a proper number of articles are engaged between the first and second jaw members (24,26).  The reference signal is stored for each insert station S in accordance with a method and apparatus for calibrating an engagement error detector (364) associated with the station S.  Upon verification at the start-up of the insertion machine (10) that the insert station S has a proper number of articles engaged between its first and second jaw members (24,26), a switch (467) is activated to store in a sample and hold circuit (369) the signal then generated by jaw displacement sensing means (369).  The engagement error detectors for a plurality of insert stations can be calibrated one-at-a-time in serial fashion or, in an alternate mode, essentially simultaneously using a master calibration switch (MCS).
