Abstract: Abstract To  retard  the  escape of hot gases and dust from batch material being charged from a mechanical batch feeder into  the  doghouse  at  the  charging  end of a glass melting furnace,  there  is  provided  an  enclosure  comprised  of  two sections, one of which is supported on the side walls of the furnace over the doghouse area and which is closed at its back above the doghouse by the suspended arch wall of the furnace, the other of said enclosure sections being entirely supported on the batch feeder. It has top and end portions, the edges of which  confront  the  top and edges of the furnace supported section when the feeder is in place to deliver batch material to the doghouse. Packing material forms a seal between said confronting edges. The feeder, however, may be quickly moved away from the furnace in case of need or emergency or for the repair of the furnace or the feeder. The back of the feeder mounted enclosure section is comprised partly of parts of the feed hopper with the batch material in the hopper forming a part of the enclosure. A flexible heat resistant fabric below the charger plate of the feeder and connected to the under-surface thereof is important in blocking the escape of gases and dust from the interior of the enclosure by flowing from the doghouse area under the charger plate, said curtain also being attached to the ends of the feeder supported section with sufficient fullness in the curtain between the charger plate and the end walls to flex with the back and forth and tilting motion of the charger plate relative to said end walls of the feeder supported section.

Abstract: Abstract of the Disclosure Disclosed is a method of producing viscous hydrocarbons from a viscous petroleum-containing subsurface formation.  At least an injection well and a production well are provided to extend from the surface of the earth into the subsurface formations.  A high mobility, brine-filled channel is established through the lower portion of the subsurface formation to communicate with the injection and production well.  After the high mobility channel is established, a solvent for the petroleum is injected into the high mobility channel.          The injection of the solvent is continued until break-through of the solvent at the production well and thereafter until the ratio of petroleum to solvent produced from the production  well becomes unfavorable.          Thereafter, gas is injected into the high mobility channel to displace the solvent and petroleum from the formation to the production well.

The cable unwinding groove, which is located opposite the winding groove in the axial direction of the disc, is bounded by a clamping disc, which is capable of being engaged by n hydraulic pressure piston against the cable.  The piston of the tensioning disc, and the piston of the clamping disc, are coupled by a hydraulic control and are capable of being engaged by pressure in opposite directions with respect to the cable.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of making a shackle bow for use under great loads, such as in anchor lines.  The shackle is formed from a cylindrical bar rod by fullering the ends to a reduced diameter, and forging the central portion into a flattened shape having the cross-section of a wide shallow U shape.  The bottom inner surface of the central section is in the form of a portion of a circular cylinder.  The ends of the bar are flattened to form end hubs with a central opening for a pin.  The formed bar is then bent in the form of a bow to provide an eye for the shackle, with two parallel end hubs spaced a selected distance apart.

Abstract: ABSTRACT OF THE DISCLOSURE An improved variable ratio steering apparatus is used to effect turning movement of steerable wheels of a vehicle.  The apparatus includes a longitudinally extending force transmitting member or bar which is connected with the steerable vehicle wheels.  A drive member is rotatably mounted on the bar.  In order to effect axial movement of the bar and turning movement of the vehicle wheels, a pinion gear is disposed in meshing engagement with an array of helical rack gear teeth on the drive member. A cam track is also provided on the drive member.  This cam track is coextensive with the array of rack gear teeth.  The cam track cooperates with a follower to effect rotational movement of the drive member as the drive member and force transmitting bar are moved axially.  This rotational movement of the drive member causes an interaction between the pinion and rack gear teeth to vary the rate of axial movement of the drive member and the force transmitting bar.  The follower advantageously engages the cam track at a location which is axially aligned with the location where the pinion gear is disposed in meshing engagement with the rack gear teeth.  This tends to minimize deflection of the components of the steering apparatus.  Although an apparatus constructed in accordance with the present invention is advantageous-ly used to turn the steerable wheels of a vehicle, it is also contemplated that the apparatus can be used in other environments.

Abstract: ABSTRACT:        A subscriber line interface circuit for connect-ing subscriber's lines to telephone exchanges which com-prises a pair of amplifiers whose outputs are connected to the subscriber's line, the input terminals of these ampli-fiers receive by means of negative feedback voltages hav-ing opposite phases depending on the transversal current I produced by the line interface circuit and independent of the longitudinal currents I accidentally produced on the subscriber's line. Two load impedances which are con-nected between the supply terminals of the amplifiers and the terminals of a d.c. voltage supply source are con-trolled by means of their control terminals by voltages which have the same characteristics as the voltages applied to the input terminals of the amplifiers but which in addition have been shifted with a certain shift volt-age Vz. Consequently, the amplifiers of the line inter-face circuit operate completely independent of the longi-tudinal currents.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a pyroelectric anemometer cap-able of providing an accurate indication of fluid flow rate.  A pyroelectric substrate has a heater element located essentially transverse to the fluid flow direc-tion. Sensor electrodes also transverse to the fluid flow direction are located upstream and downstream of the heater electrode.  A fluctuating power supply is connected to the heater electrode which results in a fluctuating voltage at each sensor electrode.  The amplitude of the fluctuations at the electrodes are compared and the difference in amplitude of fluctua-tions is indicative of the flow rate of fluid flowing thereover.  Preferred embodiments utilize a differen-tial amplifier to compare the fluctuating amplitudes and provides an output to a lock-in-amplifier which provides a fluid flow rate indicator output.

Separation between adjacent holes within the group is substantially less than separation between adjacent groups. Accordingly, while fault currents driven by voltages at two different levels are effectively extinguished, the back voltage developed by the fuse during interruption of a fault current driven by the lower voltage is prevented from exceeding a selected value.
