Patent GB-808803-A (GB)
Title: Nuclear reactors
IPC: G21C3/42
Filed: 1945-12-04
Abstract: 808,803. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 4, 1945 [Nov. 30, 1944], No. 32814/45. Drawings to Specification. Class 39(4). Energy is produced in a thermal reactor employing U<SP>233</SP>. The U<SP>233</SP> is mixed intimately with a moderator comprising an element or a compound of elements each having a mass number of less than 30, such as paraffin, heavy water or carbon. The particles of U<SP>233</SP> may be of atomic size or may be larger particles such as spheres up to 0À2 m.m. in diameter, they may be present as uranium carbide or uranium hydride. U<SP>238</SP> and U<SP>235</SP> may be present, also thorium. The heat produced generates steam which passes outside the reactor to drive a turbine. Coolants mentioned are helium, water, diphenyl and mercury vapour. The reactor may be surrounded by a reflector of Au, W, Pb or Pt. Radioactive fission products may be extracted. The U<SP>233</SP> is obtained by neutron irradiation of Th<SP>232</SP>, followed by separation of Pa<SP>233</SP> from the thorium. If powdered thorium fluoride is the substance irradiated and hydrogen fluoride is circulated at the same time at 500‹C., Pa<SP>233</SP>F. volatilizes and can be collected in a chamber where the Pa<SP>233</SP> decays to U<SP>233</SP>, a critical mass of 5 pounds not being exceeded. If thorium oxide is irradiated, volatile uranium and protoactinium fluorides can be produced by treating the oxide with HF at 500‹C. Thorium fluoride can then be converted back to the oxide for further use. In another process the irradiated mass is treated with H 2 O 2  or Na 2 O 2  in the presence of nitric acid, the acidity being adjusted to pH3, producing precipitates of thorium and uranyl peroxides. This peroxide precipitate is treated with KOH or NaOH to separate the insoluble thorium peroxide. The fission products are removed from the uranium by dissolving and reprecipitating several times. In a third method of separation the mass is dissolved in acid, pH adjusted to 1 and HF or an alkali iodate, oxalate or phosphate is added.

Title: Improvements relating to weaving
IPC: D03D47/26
Filed: 1969-07-04
Abstract: 1280679 Shuttleless looms WEINHEIMER GUMMIWARENFABRIK WEISBROD & SEIFERT GmbH 4 July 1969 [11 July 1968] 33800/69 Headings DIE and D1K A travelling wave shedding loom has its warp separated into a number of sections each woven separately with its own weft thread and the weaving progressing section by section across the warp; or around in a circular loom, so that an inserted weft loop passes through the end of a previously inserted weft loop of an adjacent section to produce a unitary fabric comprising a number of sections united by interlacing of the separate weft threads. The interlacing points may be staggered to avoid visible warp-wise lines and, in a tubular fabric, the interlacings may be pulled through to the inside of the cloth so they are not visible exteriorly. A straight loom (Figure 1) has separately shed warp sections into which weft is inserted by pivoted needles 15 operating successively across the loom (Fig. 2, not shown). The needles 15 are pivoted about a shaft 13 by a cam 21 and, apart from the inclination shown, may also be inclined so their entry into the sheds is not horizontal. To facilitate insertion the warp sections may be separated by spacers (Fig. 7, not shown) and the shed may be further opened by fingers in addition to the heald frames. In Figure 9 the weft is inserted from under the shed. In a circular loom the weft may be inserted exteriorly or interiorly of the tubular fabric by oscillating tubes 127 (Fig. 20) through which they pass. The weft (Figure 9) bobbins 22 may be located over the loom and be guided to the inserters under the loom by tubes 43 which pass through the warp. The weft may be tensioned by cam operated plates 25 (Figure 4) the plates 25 being so operated that weft is allowed to be pulled into a succeeding shed to be beaten up with the weft inserted therein to stagger the_interlacings.  Beat-up motions: In Figure 1 the weft is progressively beaten-up across the loom by sectional reeds 6. In Figure 4 the weft is progressively beaten-up by blades 6 arranged alternately on sectional baulks above and below the shed. The operation of the sectional baulks may be staggered and they may overlap two fabric sections so that each weft is beaten up more than once. In Fig. 9 both sets of blades are arranged under the warp. The blades are eccentric operated. In the circular loom of Fig. 20 a swash plate beater comprises a shaft 151 with an angled end 154 supporting a number of blades 110. In Figure 21 the weft is beaten up by sectional cam operated reeds 167. Shedding: In the circular loom of Figure 20 the warp is shed by cam operated pivoted tubes 144, through which the warp passes, the tubes 144 having extensions which remain in the shed at all times. The cams may be arranged to give a 3:1 twill weave.
