Abstract: METHOD AND APPARATUS FOR CHARGING ANODE              SCRAPS TO A CONVERTER FURNACE            ABSTRACT OF THE DISCLOSURE          A method and apparatus for charging a converter furnace with anode scraps are disclosed.  In the method and apparatus, an anode scrap pile is formed by piling anode scraps to be of a predetermined height.  The anode scrap pile is conveyed to a substantially U-shaped inclinable chute having a rectangular bottom and parallel side walls rising from the opposed long edges of the bottom, the distance between the opposed side walls being slightly greater, pre-ferably about 5 cm, than the height of the pile.  The pile is then pushed with cylinders in toward the bottom of the above-mentioned inclinable chute which has the open side between the side walls directed in the horizontal direction and the side walls positioned horizontally so as to receive the anode scrap pile.  The inclinable chute into which the anode scrap pile has been pushed is rotated with a cylinder so that the bottom of the chute is downward and the side walls of the chute are in the vertical direction.  The anode scrap pile in the inclinable chute is pushed through a fixed chute bridging the inclinable chute and a window free to open and close provided in the side wall at the hood of a converter furnace so as to charge the pile into the converter furnace.        By such a method and apparatus, a converter furnace can be charged with anode scraps without stopping of the blowing of the converter furnace.

Abstract: ABSTRACT An apparatus forms a woven closed container comprising a case hav-ing two end walls and four side walls extending therebetween.  The apparatus has a tabletop having dimensions about the same as those of the container end.  A strip carrier arranges and grips one end of a plurality of strips in parallel relationship on the table and longitudinally displaces alternate strips by about one strip width.  A gripping mechanism grips the opposite end of the strip to reciprocably displace alternate strips from the normal plane of the strips.  Transverse strips are received and directed one at a time between the strips displaced from their normal plane and the alternate strips still in the plane.  Hinged wings of the table bend the unwoven ends of the strips, which extend beyond the tabletop, normal to the table. The unwoven ends are alternately reciprocably displaced to accommodate ring members between the alternately displaced ends.  Methods are also disclosed for making a filled container formed by this apparatus rigid.  In one method, the container is fitted with inflatable bags along its side edges and is pierced to provide access to the bags.  A pressurized fluid is then forced into the bags.

Abstract: HIGH VERTICAL CONFORMANCE STEAM DRIVE OIL RECOVERY METHOD       (D#76, 018-F) ABSTRACT OF THE DISCLOSURE         The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the recovery zone between one injection well and one producing well,  with at least one infill well which is in fluid communication with no more than the bottom half of the formation.  Steam or a mixture of steam and hydrocarbon is injected into the injection well and fluids including oil are recovered from the producing well until live steam production occurs at the producing well.  Petroleum production is then begun at the infill well and continued until the water cut of the fluids being produced from the infill well reaches 95 percent.  The infill well is converted from a producer to an injector and hot water or cold water followed by hot water is injected into the lower portion of the formation via the infill well and fluids are produced from the production well. By this means, oil is recovered from the lower portions of the formation between the infill well and the production well.  After water breakthrough occurs at the production well, steam is injected into the infill well and fluids are recovered from the production well.  Hydrocarbon solvent is injected either as a slug prior to steam injection into the infill well or comingled with the steam being injected into the infill well.  By this multi-step process involving the infill well, the amount of oil recovered from the portion of the formation in the recovery zone defined by the injection and production well is increased significantly.                        -I-

Abstract: THERMAL SWITCH WITH ORGANIC GLASS BEAD MIXTURE FUSIBLE PELLET            Abstract of the Disclosure A thermal switch for automatically opening a circuit when the ambient temperature exceeds a predetermined level is disclosed which utilizes a  fusible pellet formed of an organic-glass bead mixture. The organic-glass bead pellet retains a pair of leads in contact with each other when the ambient temperature is below the melting temperature of the organic material. The addition of the glass beads to the tem-perature sensing pellet allows the compressive strength that is needed to hold the leads together to be more reliably controlled. In the process of combining the organic material and the glass beads, to form the pellet, the organic material is first melted so as to flow around the beads. Manufacture of the thermally-fusible pellet in this manner eliminates the voids which occur in the pressed organic pellets that are conventionally used in thermal sensing devices. The elimination of these voids increases the strength of the otherwise relatively fragile pellet thereby improving reliability of thermal switches which utilize the improved pellet of the present invention.

Abstract: S P E C I F I C A T I O N            ABSTRACT OF TILE DISCLOSURE           A security mounting for attaching a movable component to a stationary component has a pin with an enlarged head attached to either the movable or the stationary com-ponent.  A bracket which has a tortuous channel extending through a face plate on the bracket is attached to the other component.  Within the tortuous channel is an opening which allows the pin to be inserted into the channel.  The pin is inserted in the channel and slid along the tortuous path of the channel until the pin rests in a terminus end within the channel.  To remove the movable component from the stationary component one must have prior knowledge that it is necessary to direct the pin along the tortuous path of the channel in order to free the movable component from the stationary component.  This presents a deterrent for removing the movable component from the stationary component.

Abstract: ABSTRACT      In a polyphase machine, being either a motor or a generator, there is provided a stator core having main stator windings and control windings.  In the example of a squirrel cage induction motor these windings are wound about the stator core and the main windings have a capacitor connected in series with each such winding. In a three phase motor the control windings wound on the stator have currents in each phase which are substan-tially in phase at no load with the currents of the corresponding radially adjacent the main windings.  Such currents become out of phase with their main winding currents as the load increases.  The control windings are wound in an opposite sense to the corresponding main windings such that at low load the net flux density is low and as the load increases the flux density increases. Increase of starting and breakdown torque is achieved by having the respective poles created by the main windings and those created by the control windings placed to create a force because of the symmetry of the magnetic field.  In this case the centers of the poles of the control windings are placed as close as physically possible between the poles of the main windings, thereby improving the magnetic centering of the poles.  The voltage across the capacitor added to the input voltage may cause the stator core to switch periodically be-tween non-saturated and saturated conditions.

Abstract: (Case No. 7085) ABSTRACT OF THE DISCLOSURE A hydro-pneumatic brake actuator arranged with a slack adjuster piston and one-way check valve device in the hydrau-lic path between a hydro-pneumatic actuator and a power piston, to which a friction brake element is connected for engagement with a vehicle wheel tread or brake disc during a brake appli-cation.  During a brake release, the one-way check valve closes a passage through the slack adjuster piston to cause the piston to shift from its one extreme position to the other extreme position with the fluid flow, as the hydro-pneumatic actuator is moved from its application position to its release position.  This in turn draws hydraulic fluid from the power piston chamber into a clearance volume created by shifting of the slack adjuster piston, and accordingly forces the power piston to retract a predetermined distance corresponding to the capacity of the clearance volume and the effective area of the power piston, thereby maintaining a constant brake shoe clearance during brake release.

Abstract: Abstract of the Disclosure Method of and apparatus for obtaining a sample from a specimen of blood or the like in a closed container at a first pressure and for delivering the sample to an analyzer for analysis.  The appa-ratus comprises a hollow needle for penetrating the closed container movable from a retracted position to an extended position in which it penetrates the container for drawing a specimen sample therefrom, and back to its retracted position.  A conduit con-nects the needle and the analyzer for delivery of a specimen sample to the latter.  An aspirator reduces the pressure in this conduit to a pressure less than the aforesaid first pressure when the needle is in its extended position, a specimen sample thereby being aspirated from the container into the conduit for delivery to the analyzer.  The apparatus is responsive to this aspiration to ini-tiate transfer of the specimen sample from the con-duit into the analyzer. The pressure in the conduit is at least equal to the first pressure following aspiration, thereby enabling the specimen sample readily to be drawn into the analyzer.
