Abstract: A signalling system to indicate the position of a disconnect switch used in an electric transmission line. The switch has at least one moving contact and at least one fixed contact. The system comprises two transmitters associated with the moving and fixed contacts to transmit at least one ultrasonic signal indicating the position of the moving contact with relation to the fixed contact of the disconnect switch. A receiver assembly receives the ultrasonic signal transmitted by the transmitters and generates an output signal representative of the position of the moving and fixed contacts.

Abstract: ABSTRACT       The invention relates to seed metering and particle dispensing wheels and to mechanism for mounting such wheels or other rotative elements to a shaft.  The wheel has a C-shaped major part with a central opening for receiving the shaft, the free edges of the major part defining a slot ex-tending from the opening to the wheel periphery.  A minor part is receivable in the slot to complete the wheel.  The minor part at its inner end. and the shaft, are provided with cooperating surfaces which, when engaged, provide a drive connection between the shaft and the wheel.  To remove a wheel from the shaft the minor part is withdrawn from the slot and the major part moved transversely of the shaft so that the shaft passes through the empty slot.  Replacement or additional wheels can be assembled to the shaft using the reverse procedure.  The major and minor parts can have cooperating detents thereon to lock them together, the locking force of which can be overcome if the wheel binds while the shaft tries to rotate, so that the driving engagement between the shaft and wheel is disrupted and little or no damage to the wheel results.

Abstract: FLUIDIZED BED SULFUR DIOXIDE REMOVAL                       ABSTRACT     Method of stripping SO2  (sulfur dioxide) from flue gases by passing the SO2 containing gas through to a bed of particles to fludize said particles and to form a fluidized bed, injecting a reaction chemical into the bed and reacting it with SO2 in the fluidized bed thereby to form particles of a combined product, combining the particles with other such particles in the fluidized bed to form bigger pellets.  While said method is carried out, at least some of the pellets so formed are removed from the bed.  In the preferred arrangement the reaction chemicals are injected into the bed in an aqueous medium and gas entering the bed is at a temperature which evaporates the aqueous medium to form a dry combined product.

Abstract: Abstract of the Disclosure An improved method of casting an article decreases the time required to cast the article without affecting the quality of the article.  When a directionally solidified (DS) casting is made, molten metal is poured into a mold cavity.  One end of the mold cavity is exposed to a chill plate which initiates solidification of the molten metal.          As the metal solidifies, a dendritic structure grows upwardly into the mold cavity.  Molten metal is disposed in the interstices of the uppermost portions of dendritic structure.  As the metal in the mold cavity cools, the molten metal in the interstices solidifies and the dendritic structure, including a region containing some molten metal in the interstices, continues to grow upwardly toward the upper end of the mold cavity.  The directional solidification of the metal in the mold cavity is promoted by slowly withdrawing the mold from a furnace as the molten metal solidifies.  In accordance with the present invention, when the upper end of the dendritic structure reaches the upper end of the mold cavity, the rate of withdrawal of the mold from the furnace is substantially increased to accelerate the solidification of the remaining molten metal.

Abstract: Abstract of the Disclosure An apparatus and method for encoding only the maximum and minimum values of an analog signal in the presence of broadband noise so that the original analog signal may be subjectively reproduced to the human sensory system is disclosed.  The basic apparatus includes a differentiator for detecting the times of occurrence of minimum and maximum values of the analog waveform including the minimum and maximum values of the noise superimposed thereon and for converting the times of occurrence into time-axis zero crossings, and a clipping circuit having a bandwidth substan-tially greater than the bandwidth of the analog signal for encoding the time-axis zero crossings into transitions of a binary signal. The binary signal contains information  solely concerning the times of occurrence of the minimum and maximum values of the original analog signal and may be presented directly to the human sensory system or after further signal processing.  Because the human sensory system is more receptive to the occurrence of minimum and maximum values of a waveform, the sensory system will substantially reproduce the original analog signal from the encoded waveform.

Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a process for producing low energy vinyl dispersion resins which, in a plastisol, can be fused either at lower temperatures or in a shorter period of time than the normal dispersion grade resins presently employed.  The new vinyl resin is characterized by being a bimodal resin, i.e., containing large particles and small particles of polymer in a predetermined size and amount.  The small particles are a vinyl homopolymer or copolymer made by a regular emulsion polymerization procedure.  The large particles are a vinyl copolymer made employing a seeded emulsion ovarpolymerization procedure wherein the seed is either a vinyl homopolymer or a vinyl copolymer.  The final bimodal resin is obtained from a blend of the small and large particle latices by drying, such as spray drying, for example.

Abstract: OPTICAL INSPECTION SYSTEM                 Abstract of the Disclosure An optical inspection system is disclosed which determines surface and other features of objects by illuminating them with a light beam having substantially uniform light intensity in space and time.  The light beam is derived from a light source whose light intensity may vary in space and time.  The surface features of each object are inspected by detecting light reflected from the object through a lens system which focuses the reflected light on an array of photosensitive elements.  The output signals provided by the array may be used to provide a measure indicative of the conformance of the inspected surface to predetermined criteria.  The inspection system is further capable of determining other features of the inspected object, such as the height of the object, by illuminating the object with a second light beam derived from a second light surface.  A portion of the second light beam is eclipsed by the object and the non-eclipsed portions are directed to a second array of photosensitive elements to provide signals indicative of the desired dimension.

Abstract: METHOD AND APPARATUS FOR PERFORATING AND/OR SEVERING         TUBULAR BODIES              ABSTRACT OF THE DISCLOSURE           Tubular workpieces are formed with perforations of desired size and/or shape by repeatedly piercing selected portions of the workpieces by needles, pins or analogous piercing tools.  The tools can be stationary while the workpieces roll therealong, or the workpieces can rotate while coming into repeated engagement with one or more sets of orbiting tools.  The frequency and the number of penetrations of tools into selected portions of the workpieces are selected with a view to heat the tools as a result of frictional engagement with the material of the workpieces, i.e., as a result of repeated penetration into and extraction from selected portions of a rotating or rotating and rolling and/or axially moving workpiece.  This enhances the making of predictable perforations in tubular workpieces, especially workpieces which consist of a synthetic thermoplastic material, such as bobbins for the storage of textile yarns.  One or more knives can be provided to subdivide each discrete workpiece or a continuous tubular body into discrete sections of desired length. The piercing tools can be used to make perforations in addition to the severing action of the knife or knives, or to merely rotate and/or axially move the tubular workpiece preparatory to, during and/or subsequent to severing.  Alternatively, the piercing tools can be used to make slits or circumferentially complete cuts in tubular workpieces if the selected portions of the workpieces are contiguous, as considered in the circumferential and/or axial direction of the workpieces. Ejectors can be provided to expel successive discrete tubular workpieces from the perforating station, e.g., simultaneously with movement of one or more sets of piercing tools away from the workpiece.
