Abstract: 1471729 Ion exchange resin compositions DOW CHEMICAL CO 1 Oct 1974 [2 Oct 1973] 42589/74 Heading B2E A composition for exchanging ions comprises a substrate of particles of insoluble synthetic resin having exchanging sites on its available surface, the surface being coated with insoluble synthetic resin particles having ion exchange sites on their outer surface which attract the available sites on the substrate, wherein the coating particles constitute a monolayer irreversibly attached to the substrate, the substrate has a particle size of 5 to 100Á, and the coating particles have a median diameter of 0.1 to 5Á. The coating particles may have a size range of 0.01 to 10Á. A slurry of substrate particles packed in an exchange column is preferably coated in situ by passing a suspension of coating particles through the column. The material of the substrate or the coating may be macroporous or gel-type resins, and may be derived from polyacrylic, polymethacrylic, polyvinylaromatic or phenol / formaldehyde resins treated to be anionic or cationic exchange resins, e.g. styrene/divinylbenzene copolymer containing 2 to 8 wt.% of divinylbenzene treated to form the sulphonate or a quaternary ammonium derivated thereof. Cationic exchange resins are coated with anionic exchange resins and vice versa, and the term "cationic exchange resins" embraces chelating exchange resins. In Examples the chromatographic use of specific resins in delaying the passage a series of cations or a series of anions is described. A method of separating resin particles of the required size ranges is also described.

Patent GB-431627-A (GB)
Abstract: 431,627. Calculating - apparatus. AKTIEBOLAGET FACIT, Atvidaberg, Sweden. Feb. 1, 1935, No. 3360. Convention date, July 10, 1934. Addition to 431,623. [Class 106 (i)] In a machine for the four rules as described in the parent Specification the means provided to ensure the complete tabulation of the main actuator and of the operating member of the quotients counter is modified by the provision of a pawl on the actuator carriage which is adapted to co-operate with a rack on the carrier of the operating member in a yielding or positive manner. As shown in Figs. 1 and 2, the main actuator 31 is mounted on a carriage 34 having a spring controlled pawl 49 normally facing a rack 40 formed on the carrier 8 that supports the operating member of tooth 3 for driving the quotients counter 1. The carrier 8 is slidably mounted on the shaft 4 to which the tooth 3 is keyed and at its right hand end it is provided with a slotted plate 80 in which works a pin 42 of a U-shaped member 43, secured to a cranked shaft 44. A spring controlled pawl 46 normally engages the plate 80. The longitudinal movement of the actuator 31 and carrier 8 is controlled by the tabulating keys 16, 19, 24. By depression of the key 16 the pawl 46 is rocked out of engagement with the plate 80 and the carrier 8 is drawn to its extreme left hand position by the spring 29 until it meets the stop 52. At the same time the key lever, through a pin 53, rocks the member 43 and displaces the plate 80 and the carrier so as to bring the rack 40 into alignment with the step 49a of the pawl 49. Depression of the key 16 at the same time frees the carriage and the actuator tabulates to its extreme left hand position, the pawl 49 being pushed aside by the sloping edge 401 of the teeth of the rack 40. The key 19 when depressed rocks the carrier 8 through such an angle that the rack engages the step 49b of the pawl and this positively couples the carrier 8 to the actuator to advance the parts step-by-step. The key 24 when depressed serves to return the parts step-by-step in known manner, the carrier being moved to engage the step 49b.

Title: Improvements in homogeneous nuclear reactors
IPC: G21C7/00
Filed: 1960-12-20
Abstract: 934,223. Controlling nuclear reactors. ALLMANNA SVENSKA ELECTRISKA A.B. Dec. 20, 1960 [Dec. 22, 1959], No. 43699/60. Class 39 (4). The reactivity of a homogenous nuclear reactor containing fissile material dissolved or dispersed in light or heavy water, from which steam is produced, is controlled by having the reactor vessel 1 in communication with an auxiliary vessel 8 through a conduit 10 and passing a gas from the vessel 8 through a conduit 15 and a regulating means 16, e.g. a throttle valve, to the reactor vessel 1, the water level in which is determined by the setting of the means 16. Suitable fuel compositions include dispersions in heavy water of ThO 2  with the addition of fissile material such as U233, U235 or Pu239, and solutions in light or heavy water of uranyl sulphate containing enriched uranium. The steam produced is led via a conduit 3 to a condenser 4 and the condensate returned to the reactor vessel 1 partly directly via a conduit 7 and partly through the auxiliary vessel 8 via conduits 9 and 10. The distribution of the condensate between these two return paths is regulated by valves 11 and 12. The gas which flows through the conduit 15 has a low neutron absorption cross-section, e.g. deuterium, helium or oxygen, and enters the auxiliary vessel 8 via a conduit 13 and valve 14, leaving the condenser 4 via a conduit 17 and valve 18. In the embodiment shown in Fig. 2, the reactor vessel 1 is divided into two zones by a partition 19, the outer zone 21 containing moderator only and acting as a reflector, but this is not essential. In other embodiments (not shown), more than one auxiliary vessel 8 is used, some of which may be connected in parallel, and the gas led to a point or points along the conduit 3 as well as, or instead of, to the reactor vessel 1. Operational disturbances such as pressure surges in the reactor vessel, or loss of pressure in the gas circuit, cause the fuel composition to be carried automatically from the reactor vessel to the auxiliary vessel, whereby the steam production ceases. The volume of the auxiliary vessel (s) used should be sufficiently large to take up the total amount of fuel composition contained in the reactor vessel, if necessary. Specification 913,714 is referred to.
