Filed: 1981-12-28
Abstract: Uranium is recovered from a soln. obtd. by reacting a uranium ore with sulphuric acid, by ppn. as the peroxide by addn. of H2O2. Specifically prior to the ppn., alkali is added to the soln. to bring it to a pH equal to or slightly above theat required for ppn. of the U peroxide. The alkaline additive is Ca(OH)2, CaCO3, their mixt. or a mixt. of NaOH with a soluble Ca salt. - The alkali pptes. out the sulphates and impurities prior to the sepn. of the U, hence purer U peroxide is obtd. and less H2O2 is needed than in prior art.

Abstract: The measurement appts. uses two current circuits, one being for reference to the other in such a way that on division of signals the variations in conductivity of the fluid or material are eliminated. The second circuit is for quantity or level indication, and signals produced show percentages which are linear for presentation of level or quantity. Both indicator circuits are such that no creeping current levels out or disturbs signals. - This occurs by a phase for both circuits being screened by the placing in a non-conductive tube of metal electrodes or rings, two of these having the same polarity. Where the other rings or electrodes of both circuits have the same symbol, the different signals characterising the measurement method are obtained. (Provisional Basic advised week 84/16)(0/2)

Abstract: A method of accelerating the hardening of concrete by carbonation with a gas consisting wholly or partly of carbon dioxide. Prior to carbonation, the concrete is dewatered and/or deaerated in a closed mould in which a sub-pressure is maintained. The gas which does not react with the concrete binders and/or the water vapour formed during the carbonation reaction are removed from the concrete during carbonation. The concrete may be precarbonated by the supply of carbon dioxide gas during the actual mixing process. The wholly or partly carbonated concrete can be dried by radiation, preferably in the form of high-frequency electromagnetic waves.

Abstract: Each roller in a roller bearing has varying diameters along its length. The longitudinal surface is formed along varying radii of curvature. The diameters are functions of the contact stress along the roller, the length of the roller, any angular misalignment, and the effective diameter of the bearing. The varying diameters are such that a uniform contact stress is placed on each roller. If desired instead of the rollers, a race may be shaped to cause the uniform contact stress.

Abstract: A lockable cassette 10 for valuable papers can be inserted into a housing 20. The cassette is closed and locked when removed from the housing, and when inserted therein can be unlocked by electrical activation and opened to access the papers provided that the electrical activation is effected in accordance with a pre-set program. For this purpose there is provided a locking arrangement which includes a programmable memory (171), a comparison circuit (172), and a logic circuit (173). The memory is accessible for programming and is arranged to feed a series of pulses to the comparison circuit, which in turn compares them with a series of pulses fed-in from without to the locking arrangement. The logic circuit blocks the opening of the locking arrangement in the absence of agreement between any two pulses. This blocking of the opening function is not noticeable externally until the whope series of pulses has been compared.

Abstract: An intraocular implant of the type having a lens (12) and one or more flexible lens retaining legs (16) extending therefrom for seating in an eye chamber, in which the free end of at least one of the legs (16) has means for latching engagement with a co-operating latching portion (30) on the periphery (14) of the lens, which is so positioned circumferentially on the peripheral portion that when the end of the leg is latched therein, the leg is flexed around the edge of the peripheral portion so that the lateral dimension of the implant is substantially no greater than that of the lens and peripheral portion alone thereby facilitating insertion of the implant through an incision into the eye. Preferably the peripheral portion of the lens body has an upwardly projecting leg support member against which the leg bears when it is flexed around the lens body, which controls the amount of bending of the leg and distributes the bending throughout a substantial portion of the length of the leg. <IMAGE>

Abstract: In a data transmission system data is sent, after suitable conversion, as a ternary analog type signal. Using two-wire twisted pairs and hybrids, echo cancellation and feedback equalization are needed. Synchronization between the two ends, e.g. of a 144 Kb/sec. subscriber's loop is maintained by a low amplitude pilot tone sent with the data, and detects at the same time as the data is detected. Detection and elimination of this pilot tone use coefficient generation circuitry similar to those used in the equalizer and echo canceller.

Abstract: This describes the prodn. of consistency additive for jam, jelly, juices etc. formed by treating beet material, e.g. sugar or fodder beet, with acid. Beet material is processed with a soln. of sulphur- or mineral-acid and water, or even with any other organic or inorganic acids. The treatment may take place in two stages: first with a weak soln. to extract the pectin, and then with a stronger soln. to remove acetyl gps. from the pectin. The final characteristics of the additive depend upon the acidity (typically pH 0.5-5, and preferably 1-2.5), and temp. (typically 40-100 deg.C, preferably 75-85 deg.C). The treatment takes from 0.5 hours to 1 day (typically 1-15 hours and with the preferred pH and temp. 4-7 hours). The additive may be concentrated or pulverised.
