Abstract: A process for the preparation of polymers having an optical position in the nD-vD diagram which is expedient for optical use, by metathetic counterion exchange is characterised in that the halogen ion in a compound of the formula (I) <IMAGE>  in which R1 and R2, which may be identical or different, are divalent organic radicals, R3 and R4, which may be identical or different, are monovalent organic radicals,  n is an integer greater than 2, and  y is 0 or 1, and in which R1, R2, R3, R4, y and n are selected so that together they form a polymer backbone which promotes glass formation and prevents crystallisation, and X<-> is a halogen ion, is replaced by an equivalent of a monovalent or polyvalent, organic or inorganic counterion which is different from a halogen ion and is suitable for producing the desired solid properties. Due to their excellent optical properties (high refractive index, in particular in combination with low optical dispersion), these polymers are highly suitable for a very wide variety of applications in optics, for example for optical components, such as Fresnel lenses or optical waveguides, or as optical coatings.

Abstract: In image formation, a reversible thermosensitive medium, preferably in the form of an endless belt, is selectively heated in accordance with an electrical image signal, so that the areas of the thermosensitive belt will have different transmittances corresponding to the respective pixels of the image signal. A photosensitive member, preferably in the form of a drum, widely employed in electrophotography, is uniformly charged, and the thermosensitive belt is then superimposed on the photosensitive drum, and the photosensitive drum is exposed to light of a uniform intensity through the thermosensitive belt. The intensity of light which each area of the photosensitive drum receives depends on the transmittance of the corresponding area of the thermosensitive belt. An electrostatic image that is formed on the photosensitive drum as a result of the exposure is therefore a conversion from the transmittance image on the thermosensitive belt. A toner image may then be developed and transferred and fixed on recording paper.

Abstract: A method and apparatus are described for controlling the rate of pouring of molten metal. Examples are given of pouring metal (16) onto a steel strip (10) to form a coating (12) having a uniform controlled thickness thereon. The method comprises the use of an intermediate holding dish (26) having pouring means (28) in the form of a generally vertical slot. The metal head (50) presented to the slot is variable in response to signals from sensors (34,42) measuring, for example, total strip thickness and the metal level (50) within the holding dish. Signals from the sensors are also used to generate control signals (46) to vary the rate of pouring from a holding furnace (14) into the dish.

Abstract: A CMOS integrated circuit for driving capacitance has an input node (10) and an output node (20) and includes a first transistor (14) operatively connected to the input node (10) which is turned "on" and "off" by the input node (10) to supply an output signal to the output node (20) when turned "on". A second transistor (24) is provided, the output of which is connected to the output node (20) when turned "on" to supply an output signal thereto. A control circuit is provided to turn on the first transistor (14) prior to the second transistor (24), and to turn on the second transistor (24) if and only if the slew rate of the output signal of the first transistor (14) is less or slower than a given value. With this arrangement, if there is a low total capacitance of the capacitance devices being driven, the first transistor (14) will have a fast enough slew rate that it will perform the entire charging function of the devices without turning on the second transistor (24); however, if the total capacitance of the devices being charged is sufficiently large, the low slew rate of the first transistor (14) will cause the second transistor (24) to be turned on, thereby providing additional charging voltage to the capacitance devices, thus decreasing the time that would be required if only the first transistor were employed for the entire charging.

Abstract: The invention relates to a magazine 5 for a label stack 4 in a labelling station. The magazine 5 can be moved by means of an actuating drive between two positions, in whose one position three labels can be removed by means of a glued removal element and in whose other, set-back position (idle position) no labels can be removed. A crank drive, whose crank 12 is drivably connected via a pull and push rod 11 with built-in damping element 14 to the magazine 5, is provided for the displacement of the magazine 5. Because of its floating arrangement in the pull and push rod 11, the built-in damping element 14 damps directly as a function of the driving power both at the beginning and at the end of each actuating movement. <IMAGE>

Abstract: Apparatus of the invention includes means (5) for providing a difference signal representing the difference between first and second video signals representing earlier and later scans or numbers of scans respectively of an area being surveyed. The difference signal represents movement that has taken place between the earlier and later scans, and is fed to peak hold circuitry (6) in which it is broken up into pixel-sized bytes or subelements. If any byte is above a threshold value the associated pixel of a video display screen (7) is displayed and is maintained in the displayed condition for subsequent scans and comparisons. A track of the movement is thus built up across the screen (7). 
     The apparatus may take the form of digital vascular imaging apparatus, in which case the first and second video signals are the successive outputs of fluoroscopic X-ray apparatus, and the movement detected and imaged is the movement of a leading edge of a contrast agent injected into the vascular system.

Abstract: A laser interferometer uses an acousto-optically modulated laser (100) to produce a pair of orthogonally polarized frequency-shifted beams. The beams are passed down a monomode, polarization preserving optical fibre (110) in order to transmit the beams to a cavity (148). The beams are separated at polarizing beam splitter (128) and directed down measuring arm (130) and reference arm (132) of an interferometer. The beat frequency between the reflected beams is detected at photo-detector (146) which outputs a measuring signal (152). This beat frequency is compared to the beat frequency of the beams before entering the interferometer, which is derived by providing a semi-­silvered mirror (114) and interfering polaroid (116) in the path of the beams up-beam of the interferometer to produce a reference signal (126). The measuring and reference signals are compared to determine the movement of the measuring arm of the interferometer. This method of determining the reference signal makes the apparatus less susceptible to temperature changes.

Abstract: The invention relates to a method for producing a Ziegler-Natta catalyzer, in which method prepolymerization is performed by bringing a transition metal compound activated by a donor and an Al-alkyl, which transition metal is included in the groups IV-IV of the periodic system, into contact with an α-olefine for obtaining a stable particle-shaped prepolymer. The prepolymerization is performed by bringing as said α-olefine a gaseous 4-methyl-1-pentane at a high temperature into contact with said activated catalyzer system, owing to which high temperature the catalyzer bed is fluidized and the catalyzer parts which have not been polymerized and have smaller particle sizes leave along with the gas flow, whereby a stable catalyzer with a small particle size distribution is obtained. The invention also relates to a method for producing polyolefines by means of a prepolymerized Ziegler-Natta catalyzer.

Abstract: Membrane or pressure swing adsorption systems are used for air separation, with the crude nitrogen stream obtained thereby passing to a catalytic combustion system for reaction of residual oxygen with hydrogen to produce a high purity nitrogen product. Excess hydrogen in the nitrogen product is minimized by controlling the amount of hydrogen employed based on the instantaneous crude nitrogen flow and purity, and adjusting hydrogen ingestion in response to nitrogen product purity feedback. Plant flow rate tracking control limits maximum rates of flow change to ensure stable operation.
