Abstract: ABSTRACT                "LINEAR INDUCTIVE TRANSDUCER"       A linear inductive transducer includes a non-magnetic former 10 which has a bore 11 in which is slidable a core 16 formed from magnetic material. The core in use is moved axially within the former by the component whose axial position it is required to sense.  The former has three circumferential grooves 12, 13, 14 in which are located coils connected together to form the transducer winding the inductance of which varies with the axial position of the core.  The widths of the coils and the number of turns in each coil varies so as to produce a substantially linear variation of inductance as the core is moved.  A temperature responsive resistor 18 is mounted in close proximity to the winding and is connected in a resistance network which includes the winding.  The inductance of the winding is checked by applying a step voltage to the resistance network and monitoring the change of current in a part of the network.

Abstract: Abstract of the Disclosure A rotary filtration unit comprises a rotatable generally cylindrical filter drum assembly mounted at one axial end in a chamber formed within a housing having an inlet passage formed for supplying material to be filtered to the cylindrical outer surface of the drum and an outlet passage communicating with the interior of the drum for taking away material filtered by passage through the drum from outside to inside.  The drum assembly comp-rises inner and outer filter barrels which retain between them a cylindrical filter element such as of wire gauze or porous sintered metal.  The outer barrel has regularly spaced apart relatively large openings in its outer sur-face which communicate through the thickness of the barrel wall and via divergent passageways with even larger openings on the inner surface of the drum.  In contrast, the inner barrel has a plurality of much smaller through openings in registry with each of the large openings in the inner surface of the outer barrel.  A flushing tube extends into sealing contact with the outer surface of the outer barrel and has an opening which, depending on the angular orientation of the filter drum, either regis-ters with one of the openings therein or with the space between adjacent openings.  When the flushing tube is in registry with one of the filter drum openings, clean filtered material can back flush through the drum and flush away into the flushing tube impurities deposited on the filter.  The described unit can be used with heavily contaminated material, and can be operated such that out-let pressure fluctuations resulting from the flushing oper-ation are minimized which is particularly advantageous for example where the material being filtered is plastics stock for an extruder producing fine films or filaments.

Abstract: ABSTRACT OF THE DISCLOSURE Protective  relay  apparatus  and  methods  for detecting direction to a fault from a measuring point on an A.C. electrical power transmission line using current and voltage deviation signals which may include traveling wave transients,  and for providing both directional and distance information from the same signals after traveling wave transients have been removed.  Fault generated cur-rent and voltage deviations from the steady-state, pre-fault magnitudes are used to generate trajectories in one embodiment by differentiating the current deviation and using it as  one  coordinate,  and by using the voltage deviation as the other coordinate.  A forward fault pro-duces a straight line trajectory which crosses the origin between the second and fourth quadrants, and the reverse direction fault produces a straight line trajectory which crosses the origin between the first and third quadrants. Providing threshold boundaries in the quadrants and de-tecting a crossing thereof provides fault direction ac-cording to the quadrant in which the crossing occurred.

Abstract: ABSTRACT OF THE DISCLOSURE A  fragile  article  such  as an  electric  lamp having a glass bulb of spherical, paraboloidal or general pear-shaped  configuration  is  protectively  packaged- by inserting it into snug slip-fitted relationship with an open-ended hexagonal  sleeve-like  carton of boxboard or other  suitable  packaging  material.   Parts  of  opposing walls of the carton are cut, scored and interconnected to provide  a foldable  flap assembly that is automatically actuated when the carton is expanded from collapsed condi-tion and is then converted in "snap-like fashion" into a laterally-extending platform that locks the carton in its fully-erected  tubular  configuration.   The  platform  is provided with a suitable aperture which frictionally grips the basal end portion of the inserted lamp and thus holds the lamp in loaded position within the carton.  The unique snap-locking flap assembly accordingly not only serves as an integral article-retaining and bracing means for the carton  which  greatly  facilitates  the  setting-up  and carton-loading operations  but  provides  window openings which attractively display the packaged lamp.

Abstract: ABSTRACT OF THE DISCLOSURE In a continuous steelmaking method, a molten metal bath is maintained within a rotary furnace heated by oxy-fuel burners at the charge and discharge   ends.  Metallic iron charge material such as iron and steel scrap or sponge iron is preheated primarily by heat transferred from the furnace exhaust gases, on an enclosed recuperative conveyor before being introduced through the charge end opening.  Molten metal is withdrawn through a siphon tube submerged in the bath through the furnace discharge end opening into a vacuum chamber which is part of an integral vacuum chamber-tundish combination incorporating a molten metal column under vacuum in one leg and a molten steel tundish casting pool under atmospheric pressure as the other leg, connected via a submerged channel.  As steel is cast out of the tundish through a submerged nozzle, it is replenished by way of the column from vacuum-induced flow through the siphon tube, metal surface levels in column and tundish remaining substantially constant once casting has been established Several means are provided for regulating withdrawal and casting rate, including the use of slide-gate valves and varying the vacuum pressure, and also a procedure for initiating the method without pre-filling the vacuum chamber-tundish with starting molten metal.  Optional features include oxygen injection into the vacuum chamber, argon stirring for degassing and alloy additions through a sealed conduit or by injection.  According to the invention, continuous flow of material may be realized from charging and preheating of the charge through to continuous introduction of the steel into the casting molds, with only a very small vertical descent between charging and pouring.  Other salient advantages include very high overall energy efficiency, low capital costs, negligible furnace to mold temperature losses, efficient steel degas sing high alloy recoveries, flexible steel chemistry control, wide range of acceptable charge materials, and clean pollution-free operation.

Abstract: PROTECTIVE CIRCUIT ARRANGEMENT FOR SHEATHED             HEATING ELEMENT ABSTRACT OF THE DISCLOSURE     A protective circuit arrangement for sheathed heating elements which interrupts ground fault conditions by effectively decoupling the power line from the heating element regardless of the polarity of the power supply connections. A fusible link couples each side of the heating element to the power supply. A normally open switch responsive to current in the ground path switches a relatively low resistance shunt current path across the heating element when the ground current exceeds a predetermined  threshold level. Closure of the shunt path enables sufficient current to flow in the power supply lines to actuate the fusible links. Circuit parameters are selected such that the current in the fusible link coupled to the hot power line is sufficiently greater than that in the fusible link coupled to the neutral line to cause the hot power line fusible link to be actuated first, thereby interrupting the fault condition and decoupling the hot power line from the heating element.
