Abstract: ABSTRACT OF THE DISCLOSURE:         Herein disclosed are a method and a device for manufacturing multi-ply sheets of extrudable plastics material supplied by way of two webs which are produced by extruders having flat sheet dies and which are bonded to a structured insert web by means of rolls.  The multi-ply sheets thus produced are especially for use with a shower enclosure.  In manufacturing such multiply sheets it is difficult to obtain a reliable bond between the webs and the structured web without sophisticated machinery.  There is also the requirement that the structured web be uniformly introduced between the webs.  The disclosure proposes to feed these webs to a single common set of rolls and to arrange the flat sheet die of one extruder so close to a set of rolls that a reliable permanent bond to the struc-tured web and/or to the other web is obtained by the heat accumulated and carried in the one web just extruded.

Abstract: METHOD FOR HEAT TREATING PULVEROUS RAW MATERIAL AND CALCINING COMBUSTOR THEREFORE                 ABSTRACT OF THE DISCLOSURE         A calcining combustor for the suspension pre-heater of a rotary kiln cement manufacturing plant having a cooler for the clinker comprises an upright furnace vessel having an outwardly spiraling gas exhaust duct at its upper end leading to a preheater gas/meal separator and a mixing portion at its lower end; an inlet for hot combustion air from the cooler into the mixing portion; an inlet for cement meal from the preheater into the mixing portion downstream from the combustion air inlet to entrain the meal in the rising combustion air; and burners for injecting fuel into the air/meal stream downstream from the meal inlet to calcine the meal by heat released by burning of the fuel with the combustion air.  The initial calcina-tion temperature is a minimum because the combustion air atmosphere within the combustor is devoid of significant amounts of carbon dioxide and chlorine and alkali vapors typically present in kiln-off gases, and the endothermic calcination reaction absorbs heat energy to limit temperature rise within the combustor so that caking and formation of alkali and nitrogen oxide vapors is minimized. An alternative embodiment has an inlet for hot kiln-off gases into the furnace vessel at a point where substantial calcination has occurred so that both (a) calcining and (b) mixing of the calcined meal/air stream with the kiln-off gases to transfer heat energy thereto occur in a single vessel.

The electrical bridge includes first and second legs (28,30) each having a fixed resistor (22,22') in series with a coil (18,18'). The first and second legs (28,30) are connected in parallel whereby a resistor junction (24) and a coil junction (26) are formed at the extremities of the legs.  A voltage oscillator (20) is connected to the resistor junction (24), and means (32) for maintaining a constant voltage are connected to the coil junction (26). A differential amplifier (36) is connected (A,B) to each leg between the fixed resistor (22,22') and the coil (18,18') such that the differential change in coil reluctances due to pressure variations, is amplified and manifested in a readout unit (34). This bridge is particularly advantageous when the oscillator (20) and electronic processing components (22,36,34) are to be located remotely, such as outside a nuclear containment building (10), relative to the sensing coils (18).

Abstract: ABSTRACT       A mold for forming a gasket-receiving groove in concrete pipes or the like is described.  The mold, which is relatively easy and inexpensive to produce and comparably simple to use comprises a one-piece annular body with a smooth inner surface which is provided with a circumferential channel.  The depth of the channel is less than the radial thickness of the body.  Within the channel a resilient split ring is slidably disposed.  The resiliency of the ring urges the ring to expand radially outwardly towards the bottom of the channel into its expanded position.  Releasable pressure means are provided for urging the split ring radially in-wardly into a groove-forming position.  Release of the pressure means allows the split ring to return to the ex-panded position.

Abstract: METHOD AND APPARATUS TO IMPROVE CIRCULATION        CONTROL IN FLUIDIZED SYSTEMS                             Abstract Methods of and apparatus for improving fluidization of a particulate material flowing through a fluid conductor is provided by controlling the rate of addition of fluid, such as aerating gas or steam at a plurality of spaced apart locations along the conduit.  The composition and rate of flow of the fluidized particles, such as catalyst shale, coal, or tar sand, is controlled by positioning a source of penetrative radiation such as neutrons, gamma rays, or X-rays at any location along the conduit so that the radiation traverses the fluidized particulate material flowing therein.  A radiation detector is positioned opposite the source so that radiation absorbed in the conduit by the fluidized mixture may be measured as an electrical quantity.  This electrical quantity may represent the total numbers of gamma rays of a presel-ected energy interacting with a detector in a given time interval or the average number of all gamma rays generating electrical pulses by interaction with the radiation detector.  In accordance with such measured electrical quantity, the rate of flow of fluid into the conduit is adjusted in an amount and to an extent necessary to maintain the measured electrical quantity within preselectable range of values representative of stable composition and desired flow rate of the par-ticulate material.          In an apparatus form, the method is applic-able to a fluid catalytic cracking system to control continuously circulated catalyst in an aeration gas, such as steam.  By proper control of steam at a plur-ality of positions along the conduits a homogeneous dispersion of gas bubbles and particulate material at a given mixture is obtained.  This prevents slumping or bridging of particulate material in the conduit by inadequate gas flow, or over-aeration of the mixture or generation of bubbles which either decrease cata-lyst flow or result in unstable operation by forming expanding and collapsing gas bubbles, which may in turn set up mechanical vibrations in the conduit and interconnected vessels.  The result is a substantial increase in system processing capacity at reduced costs in steam and plant maintenance.

Abstract: ELECTRIC GENERATOR THAT OPERATES WITH    FEW AMPERE-TURNS IN FIELD WINDING            Abstract of the Disclosure:        The electric generator of the present inven-tion has a plural-section main winding; and it uses uni-directional  devices  to  permit  current  to  flow through various sections of that winding as the rotor poles move away from various of the stator poles of that generator but  to prevent current  flow through those various sections as those rotor poles approach those  stator  poles.   By  preventing  current  flow through those various sections, as those rotor poles approach  those  stator poles,  the  present  invention relieves the field winding of all need of overcoming the magnetomotive force of that main winding.   As a result, fewer ampere turns are needed to enable that field winding to provide the magnetomotive force for that main winding.        In some preferred embodiments of the present invention,  an exciting winding has sections thereof that are wound on poles which have turns of the field winding  wound  thereon.   That  exciting  winding  res-ponds to the magnetic lines of flux from the field winding to provide a power amplification that further reduces the number of ampere turns required for that field winding.  The sections of that exciting winding are connected to the sections of the main winding to develop a D.C. exciting current in that main winding, and that exciting current enables that generator to provide a desirably-high output.

Abstract: ABSTRACT A process for the production of a multicoloured floor covering having an under layer of polymer material, which penetrates the upper layer in a pattern of surface areas in which an upper layer of polymer material that displays a higher flow viscosity than the lower layer during the pressing process is pressed together with this lower layer and bonded with it to form one piece. The upper layer is removed from the areas so mentioned in sub-areas forming a mosaic.  The pressing process is such that the sub-areas are filled with the under layer material, and consolidation is carried out.  The floor covering has superior appearance and wear characteristics by comparison with prior-art coverings.
