Patent GB-1387166-A (GB)
Title: Electrically conductive layers upon high-ohmic substrates
IPC: H01C17/06
Filed: 1972-09-15
Abstract: 1387166 Resistors SIEMENS AG 15 Sept 1972 [17 Sept 1971] 42810/72 Heading H1S A resistor is formed by bombarding a highohmic substrate 3 with high energy (greater than 5KeV), ions or neutral particles so that the superficial layer of the substrate exhibits radiation damage 7, and (preferably simultaneously), vapour- or atom-depositing low energy (a few e.v.), particles to form separated islands 5. The high and low energy particles may be particles of metals or semi-conductors, e.g. gold, silver, platinum, nickel, iron, chromium, aluminium, alloys containing any of the above, carbon, silicon, germanium or semi-conductor compounds. The substrate may be intrinsically conducting silicon, oxides and nitrides, e.g. silicon dioxide, synthetic resin, amber, or glass. The high energy particles penetrate many atom layers deep into the substrate and remain there. The relative rate and quantity of low energy particles are selected so that only separated islands statistically distributed over the substrate are formed, and so that disintegration by high-energy particle bombardment is at a slower rate than low energy particle adsorption. Radiation damage is suffered underneath the islands and helps to adhere them to the substrate. The islands may be a single or few atom layers thick, and may have diameters of only a few atoms, but generally of the order of 1 mm. To ensure that the areas between the islands are free from adsorbed particles, the layer is annealed. As shown, electrodes 9 and 11 contact the layer 3. Current flow between the electrodes is through the high ohmic areas 7, and the lower resistance islands 5. High value linear path resistors can be formed, with consequently low inductance and capacitance.

Title: Improvements in or relating to the production of uranium values
Inventor: HAMLIN ANTHONY GEORGE
IPC: G21C19/46
Filed: 1959-12-17
Abstract: Uranium values are separated from impurities by feeding an aqueous acidified solution, for example nitric acid solution, containing uranium values and impurities to a chromatographic column of alyophobic, organic polymer in microporous form, preferably poly (trifluoromonochloroethylene) powder, supporting an organic solvent which retains uranium such as tributyl phosphate, tri-iso-oclytamine, or tri-n-octylamine.  The column is washed with acid to remove impurities, and uranium eluted with water.  The process may be effected continuously by moving the columns of chromatographic material through a series of chambers, different steps in the process being effected in different chambers.  The process may be used to separate uranium from its daughter products, radium, bismuth and polonium, and for example, from chromium, copper, aluminium, nickel, vanadium, calcium, iron, molybdenum, tungsten, sodium, potassium, fluoride, phosphate, sulphate, and chloride, and from concentrated solutions of citric acid.  Uranium may also be separated from cerium; cerium IV is retained on the column after washing with nitric acid and is subsequently eluted with water, but can be separated if the cerium is first reduced to cerium III by passing sulphur dioxide through the aqueous feed solution.  Plutonium and thorium may be separated from uranium by using hydrochloric instead of nitric acid, and reducing either the plutonium to the trivalent state with, for example, hydroxylamine, or the uranium to the quadrivalent state, before the solution is fed to the column.  If tri-iso-octylamine or tri-n-octylamine is used as the organic solvent, sulphuric acid may replace hydrochloric acid or nitric acid.  In the example polytrifluoromonochloroethylene) is ground in a microhammer mill and the powder passing a 100 B.S.S. mesh and retained by 200 B.S.S. mesh collected.  A column of 25 grams of the powder, and 25 mls tributyl phosphate as a slurry in 5,5 M nitric acid is prepared, and used to separate uranium from 20 mls. of 5,5 M nitric acid containing 1 gram uranium and 1 gram ferric chloride. The column is washed with 5,5 M nitric acid, and the uranium eluted with water.  The column is reactivated by washing with 5,5 M nitric acid.

Convention date, July 27, 1933. [Class 106 (i)] In differential mechanism for cash registers and similar accounting machines including a driving member adapted to be given a constant excursion at each machine operation and a driven member normally coupled thereto by a latch carried by the driven member, the latch comprises a locking pawl pivoted to a coupling member in such a manner that both the pawl and the member perform essentially arcuate movements each time the coupling is disabled.

Abstract: 931,068. Knitting. W. W. ARTZT. Dec. 12, 1961, No. 44385/61. Class 74 (2). A pile fabric is formed by knitting a base fabric of a stretch nylon yarn 10 and either knitting with the nylon yarn or laying in the base fabric a cotton yarn 12 in such a manner as to form pile loops of varying length. This may be achieved by using a wheel having projections or nibs of different size and which nibs engage the cotton yarn to form it into pile loops of different size. The cotton yarn is fed to the machine under great tension whereas the nylon yarn is fed under negligible tension to accentuate the variations in loop length. Moreover, the cotton and nylon yarns in each course may be of opposite twist and in succeeding courses the nylon yarn may be of opposite twist as well as may be the cotton yarn. Subsequently the fabric is shrunk, for example, to 50% of its original dimensions.
