Title: Process for removal of radionuclides from milk
IPC: A23C9/146
Filed: 1961-08-17
Abstract: Radio-active cations such as Sr-90, Sr-89, Ba-140 and Cs-137 are removed from milk by adjusting its pH to between 5 and 6, preferably 5.2 and 5.4, with an edible organic acid, e.g. citric or lactic acid, and contacting it with a cation exchange resin, e.g. of sulphonic or carboxylic acid type, which has been charged by contact with an aqueous salt solution containing non-radio-active cations in proportions substantially the same as in the milk, e.g. Ca, K, Na, Mg, and having substantially the same pH (viz. 5 to 6), the resin being washed free of excess salts The p milk may then be restored to its original pH by contacting it with an hydroxyl type cation exchange resin or by adding an alkali metal hydroxide, eg. potassium hydroxide to it. The milk product has a non-radio-active cationic composition which is substantially that of the milk prior to processing.

Title: Incinerator and method of treating refuse
IPC: F23G5/44
Filed: 1966-10-27
Abstract: In an incinerator for burning refuse on a continuously reciprocating grate GM, the combustion products pass around baffles 18a and 22, through a spray of water 34, then around ceramic pillars 28 in a gas scrubber G.S. to a plenum chamber 36, from where they are drawn upwardly by a fan 44 through a deflecting arch DA to impinge on the walls of a drying chamber DC where the water is separated before the gases are discharged to atmosphere, the water and the ash particles collected in the scrubber flowing down the sloping floor 24a thereof to a trough 108 and hence to a trough 112 containing a sludge conveyer SC, and the trough 112 leading to a sump 114 from which water is pumped to a manifold 30 for supplying the spray 34. Combustion air is supplied to the combustion chamber through nozzles 96 in the side walls and from a duct beneath the grate. The grate comprises perforated members (52) resting on grate carriers 54 which are supported by a framework of I-beams 56, 58 which is supported on stationary rollers 60 which are journalled on stationary brackets on a partition 62 and a pair of shoulders of the combustion chamber sidewalls. The framework also carries five rows of rollers 68 to support channels 66 secured at 70 to the front wall of the furnace so that the grate reciprocates beneath the channels which support inverted channels 72 having ratchet like projections 76 which assist in moving the charge along the grate. Reciprocations are imparted to the grate through a drive-shaft 82 having three pinions 80 which mesh with three racks 78 mounted on the framework. The front and rear portion of the grates have dead plates 138 replacing the members (52). The grate discharges onto an ash conveyer A.C. (Fig. 7) which comprises an endless travelling belt having blades to carry away the ash.

Patent ES-348843-A1 (ES)
Title: Method and apparatus for the continuous ringless spinning of yarn from separated staple fibers in a rotating spinning chamber
IPC: D01H4/10
Filed: 1967-12-30
Abstract: In a method of break-spinning using a rotary spinning-chamber having a collecting surface for the separated fibres and a withdrawing channel, the yarn passes over a rotary surface in its path between the collecting surface and the withdrawing channel, so that it is deflected and subjected to friction. The chamber 1 is arranged to be driven inside a stationary housing by a wharve 7. The cover 9 of the housing also closes the chamber, and has an inlet 10 for fibres separated at 12, and a channel 15 through which yarn is withdrawn by rollers 16. The side wall of the chamber is inclined and acts to guide fibres delivered at 10 to a collecting-surface 14 which is formed between the wall and the inclined surface 201 of a rim 20 concentric with the base of the chamber. The rim 20 projects upwardly above the direct line between the collecting surface and the yarn outlet so that the yarn is deflected and is entrained by and subjected to friction on the surface 201. This prevents a change in the direction of movement in the point when the yarn picks up the fibres, due to impurities or accumulations of fibres. Forms are described in which the rim has a flat upper surface, Fig. 4 not shown, and in which the fibres enter the chamber at the end opposite that through which it is withdrawn.
Patent ES-350833-A1 (ES)
Title: Sheet Control Means for Printing Presses.
IPC: B65H9/20
Filed: 1968-02-23
Abstract: Sheets being fed to a printing-machine in overlapping relationship or otherwise are detected by photo-electric cells 6, 7, which in the event of a sheet being askew or absent stop the feed rollers 9 and the printing-machine. When the feed is started, a third cell 5 is operative to prevent the cells 6, 7 from acting, so that the feed continues during the time before any sheet has reached the cells, but when a sheet is detected by the cell 5, the latter is rendered inoperative to affect the cells 6, 7, which thereupon will stop the feed if a sheet is absent or askew.

Patent ES-396448-A1 (ES)
Title: Nuclear reactor fuel elements
IPC: G21C3/33
Filed: 1971-10-08
Abstract: The invention relates to a nuclear reactor fuel element assembly which is in the form of a bundle of parallel fuel pins extending between top and bottom end fittings in the assembly. The top and bottom end fittings are held together by a number of lifting pins which are screwed into the bottom end fitting and have spigots extending through the top end fitting and fitted with retaining nuts. A fuel pin locking member consists of a U-shaped split pin having its legs extending through transverse drillings in the retaining units and spigots of two adjacent pins. Thus the retaining nut of each pin is locked to the spigot and the locking member prevents relative rotation between the pins and hence prevents unscrewing of the pins from the bottom end fitting.

Patent ES-403243-A1 (ES)
Title: Low disparity bipolar pcm system
IPC: H04L7/02
Filed: 1972-05-27
Abstract: There is disclosed herein a signalling process for a PCM transmission system having reduced disparity, that is, a substantially equal number of binary "1" digits for the pulse stream. This is accomplished by complementing normal PCM words if the number of binary "1"s in a word are less than n/2, where n is equal to the number of digits per word, and using alternate-polarity bipolar code PCM transmission. In accordance with the present invention the complementing of PCM words is indicated by a polarity violation of the bipolar code of the first digit of the complemented words. This results in two pulses of the same polarity being adjacent each other rather than alternate polarity as is usual in alternate-polarity bipolar PCM. Transmission and reception circuits are also disclosed to implement the PCM signalling process of this invention.
