Patent ES-351926-A1 (ES)
Title: Neutron-absorbing graphitic product and method of preparation
IPC: G21F1/06
Filed: 1968-03-23
Abstract: A neutron absorbing material consists of a compact body of artificial graphite powder bound by coke resulting from the carbonization of pitch or coal tar, with a neutron absorbing compound selected from boron nitride, dehydrated borocalcite and oxides of rare earth metals dispersed throughout in powder form. The graphite powder can be made up of two parts, one having a particle size less than 80Á and the other a particle size within the range 0À5 to 1À5 mm. In order to facilitate subsequent extrusion, up to 10% by wt. of the graphite-neutron absorbing compound mixture may be replaced by lamp-black. The neutron absorbing compound has a particle size less than 80Á and the mixing operation is carried out in a heating mixer at a temperature between 100 and 150 C. in order to eliminate the water content. Once the compound has been completely dispersed, a binder such as coal-tar, pitch or petroleum asphalt in a proportion between 15% and 30% by wt. of the dry mixture is added to form a paste which is extruded or press-formed to the desired shape. It is then transferred to a furnace in which it is baked without exposure to air in order to carbonize the binder, preferably beneath a layer of coke powder, at a temperature below that at which reduction of the neutron absorbing compound by carbon takes place at an appreciable rate. This temperature should be in the range 900 to 1700 C., preferably between 1000 and 1200 C., but below 1150 C. in the case of borocalcite. The use of boron nitride enables a boron content as high as 15% by wt. to be attained whereas the use of the lower cost borocalcite does not result in a boron content greater than 6% by wt. Rare earth oxides permit the fabrication of parts which can be irradiated to very high doses since they do not give rise to helium evolution by the (n, [alpha]) reaction. The material may be used as a shield against fast neutrons or as a fast reactor control member. In the latter application, it is advantageous to employ oxides containing a high proportion of the rare earths which have a particularly high neutron capture cross-section, especially gadolinium oxide.

Title: Folding mechanism for rotary printing presses
IPC: B65H45/28
Filed: 1968-12-18
Abstract: A collecting cylinder is provided with five sets of collecting pins or grippers around its periphery and is associated with sheet-removal means at two positions spaced at 120 degrees around its circumference, the arrangement being such that, regardless of whether sheets are collected or not, there are breaks in the flow of sheets through either of the sheet-removal means to allow subsequent folding devices to run at reduced speeds. Fig. 1 illustrates apparatus in which a web 1, which has been printed by a plate cylinder having four different pages on its circumference, is severed by cutting cylinders 2, 3 to produce sheets corresponding to each page, which are transferred to collecting cylinder 4 provided with five equally-spaced sets of pins or grippers. Transfer cylinders 5, 6 are spaced 120 degrees apart around the periphery of cylinder 4, and are associated with folding cylinders 17, 18 which deliver the sheets to positions DI, DII, DIII, DIV. An alternative arrangement (Fig. 4, not shown) provides cutting and folding blades on the collecting cylinder. Operation of the pins or grippers is controlled by a stationary cam 7 fixed to the machine, and a rotating cam 11 on the end face of cylinder 4 (also Figs. 2 and 3, not shown), the pins being withdrawn or the grippers opened only when corresponding recesses in the cams are aligned. Three modes of use are possible: (i) non-collecting production where alternate sheets are transferred to cylinders 5 and 6, and are delivered to respective positions DI, DII, DIII, DIV (ii) single-collection where cylinder 5 is inoperative, and two sheets are collected on cylinder 4 before transfer, the first pair being delivered to position DII, the second pair to position DIV (iii) double-collection where all four sheets in a set are collected on cylinder 4 before transfer, are transferred to cylinder 6 and delivered at location DIV. In each of these modes of use there will be a break in the stream of sheets being fed to a particular folder, so that it can operate at reduced speed.

Filed: 1969-03-28
Abstract: A method of obtaining sterile, sedimented myxovirus (influenza, para-influenza, measles and mumps) from a liquid growth medium in which the virus has multiplied involves: (A) successively passing the growth medium through filter pads having the determined porosity of (i) relatively large pore filter (cellulosic pads, diatomaceous earth or spun glass), (ii) 0.8 to 2.0 micron pores (preferably 1.2 microns) and (iii) 0.22 to 0.6 micron pores (preferably 0.45 micron), and (B) centrifuging the filtrate in a 50,000 to 89,000 g field. The filtration may be preceded by a clarifying centrifugation of about 15,000 g. There should be about 100 sq. cm. of filter pad area for each 1 to 1.5 litres of the growth medium passed, and flow rates of I to 1.5 litres per 10 minutes. Air pressure of about 20 lbs. per sq. in. may be applied at each filtering step. The virus may be killed, e.g. with formalin, at any stage in the method. The final concentrated virus may be diluted with physiological phosphate buffer to produce a vaccine, or lyophilized for subsequent resuspension. Examples 1 and 2 are directed to the recovery of A2 and B strains of influenza, respectively, from their liquid growth medium.

Title: Oscillating monitor for fissile material
IPC: G01N23/09
Filed: 1972-08-04
Abstract: A device for monitoring fissile material has a neutron source that oscillates between a location near and a location remote from a neutron detector.
