Abstract: A plasma reactor, in which particulate matter is caused to interact with low temperature plasma (i.e. below 100,000 K.) comprises spaced stationary electrode structures 2, 11 of which at least one is annular, between which an arc or arcs 7 is established by a power supply which may include a thyristor (SCR) 9. The arc is pulsated and caused to orbit or circulate round the or each annular electrode structure to form a conical plasma zone between the electrodes, while particulate solids are introduced through inlets 5 to enter the plasma zone and interact with the plasma therein. Extended dwell periods and highly effective interaction are brought about by circulation and pulsation of the arc and a high particle population density. The arc can be circulated at high speed by electrical means, for example by sequential energization of plasma torches 1 in an annular array or of the segments 8 of a segmental anode, or by electromagnetic circulation of the arc attachment round an annular cathode or round a segmental anode with the help of coils 10 fitted between the segments. Examples of reactions that can be efficiently conducted by this method include the reduction of metal ores, beneficiation of low grade chromite ores, recovery of energy values from low grade carbonaceous matter such as colliery wastes and the formation of pozzolanic material and cements from siliceous minerals.

Abstract: An internal combustion engine combines the efficiency of a radial engine with the practicality of a piston and crankshaft arrangement. A stationary frame supports a stationary sun gear, and a rotor is pivoted about the axis of the sun gear. The rotor carries three crankshafts at 120° intervals, each having an eccentric portion. For each crankshaft there is a cylinder in the rotor, a piston mounted for reciprocation in each cylinder, and a connecting rod from the piston to the eccentric portion of the corresponding crankshaft. Each crankshaft is fixed to rotate with a respective planetary gear, and all the planetary gears mesh with the sun gear and have the same pitch diameter as the sun gear, so that any point on the pitch circle of a planetary gear describes a cardioid as the planetary gear rotates around the sun gear once. The crankshaft eccentricity is substantially 1/3 times the pitch radius of a planetary gear. The eccentric portion of each crankshaft has roller means rotatable about the same axis as the connection between the connecting rod and the eccentric portion, and a ring member with an internal surface surrounds and contacts all of the roller means simultaneously, the ring member being free to rotate about its own axis. Fuel metering means provide a combustible mixture for the cylinders, and ignition means are provided to ignite the combustible mixture in each cylinder. Three valves admit the combustible mixture to each cylinder, each valve having a valve shaft and a valve head at one end of the shaft. The shaft reciprocates in a bore of the rotor, the bore being substantially radially arranged with respect to the rotor axis. The shaft has at its end remote from the valve head a roller adapted to contact the inernal surface of the ring member over a fraction of each rotor revolution, thereby to depress the valve for the admission of the combustible mixture. Porting means are provided for exhausting products of combustion from each cylinder.

Abstract: The inventive process forms a thermoformable preform by pressure laminating a layer of cloth fabric to one face of the thermoplastic substrate, preferably as the substrate is extruded and while still hot from the extrusion process. This fabric/thermoplastic laminated preform can be easily processed in a matched mold press. The fabric should be of a non-stretch type. This non-stretch characteristic, together with its intimate bonding to the thermoplastic substrate, prevents the substrate from thinning in the corner regions. Indeed, because the intimately bonded fabric drags or pulls the substrate from a number of directions as the corner regions are formed, the thermoplastic substrate accumulates and actually thickens in the corner regions, leading to a shell which is remarkably durable and aesthetically pleasing.

Abstract: A a series of m-bit information words is converted to a modulated signal. For each information word from the series, an n-bit code word is delivered. The delivered code words are converted to the modulated signal. The code words are distributed over at least one group of a first type and at least one group of a second type. When a code word belonging to a group of the first type is delivered, its group establishes a coding state of a first type. When a code word belonging to an group of the second type is delivered, a coding state of a second type is established which is determined by the information word which is to be converted to the delivered code word. When one of the code words is assigned to the received information word, this code word is selected from a set of code words which depends on the coding state established. The sets of code words belonging to the coding states of the second type are disjunct. In this coding method, the number of unique bit combinations that may be established by the code words in the series are enlarged. The modulated signal obtained may be reconverted to information words by first converting the modulated signal to a series of code words and then assigning an information word to each of the code words from the series in dependence on the code word to be converted and also in dependence on the logical values of the bit string bits which are situated at predetermined positions relative to the code word.

Abstract: A process for producing and fixing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizer and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizer can absorb radiation of a sensitizer wavelength which does not, in the absence of the sensitizer, cause decomposition of the superacid precursor to form the corresponding superacid. The secondary acid generator is capable of acid-catalyzed thermal decomposition by the first acid to form a second acid, and the image dye undergoes a color change upon contact with the second acid. The medium is imagewise exposed to radiation of the sensitizer wavelength, thereby causing the sensitizer, in exposed areas, to decompose superacid precursor with formation of the fist acid. The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the second acid. The components of the acid-generating and color-change layers or phases are mixed so that in exposed areas, the second acid causes the image dye to change color. At least the non-exposed areas, a copper compound and a reactive material more reactive than the image dye to the products resulting from decomposition of the superacid precursor in the presence of the copper compound, are used to decompose the superacid precursor and fix the image.
