Abstract: 1,025,389. Electron beam apparatus; X-ray tubes. AKUSHI SEISAKUSHO KABUSHIKI KAISHA. Dec. 7, 1962 [Dec. 9, 1961], No. 46271/62. Heading H1D. In an X-ray microanalyzer the incident electron beam e is deflected at 8 so that the resulting X-rays x may be observed at right angles to the surface of the test sample 9. It is explained that this reduces errors due to shading at local concavities in the surface under test and also improves the ratio of the detected intensity of the characteristic X-rays to that of the continuous ones. The electron beam passes through two electromagnetic condenser lenses 4, 6 before reaching the deflector 8; as shown, this is a single fan-shaped electromagnet but to reduce aberrations a double arrangement may be used (Fig. 2, not shown). An analysing crystal 11 is movable along the path of the X-rays and, with a detector 12, is rotatable about its centre. The detector is connected through an amplifier 13 to a counter 14 and recorder 15. Electrons diffracted from the surface along a path f are detected by a photographic plate 16.

Title: Apparatus for scanning a surface with a beam of charged particles

IPC: H01J33/00
Filed: 1962-12-10
Abstract: 976,164. Particle accelerators. VARIAN ASSOCIATES. Dec. 10, 1962, No. 46557/62. Addition to 949,172. Heading H1D. In apparatus, such as a particle accelerator, for scanning a surface with a beam of charged particles having a particle energy gradient across it, the beam is directed through a time-varying magnetic or electrostatic field in such a manner that particles of greater energy pass through a portion of the field where the intensity is greater than the portion through which pass particles of lower energy, whereby particles of different energies are simultaneously deflected through approximately the same angle. As shown, an electron beam 10 having higher energy particles on the right 11 and lower energy particles on the left 12 is passed through the gap between two electrodes 13, 14 so shaped and disposed that the intensity of the electric field between them is greatest on the right and the least on the left, so that when a time-varying voltage is applied between the electrodes all the particles are deflected in the directions indicated by the arrows 15 through approximately the same angle in spite of the difference in their energies. The electric field gradient may be produced by applying different voltages across two electrode systems (Fig. 2, not shown). Where a magnetic field system is used the flux density gradient across the field is produced by using shaped magnetic poles or a quadrupole arrangement (Figs. 3 and 4, not shown). Specification 959,674 also is referred to.

Abstract: A heat-sealable film comprises a layer of stereoregular polypropylene, which has been subjected to a surface oxidative treatment, and an adhering coating layer on at least one of the surfaces of the polypropylene, which coating layer comprises industrial nitrocellulose, defined as having a nitrogen content in the range 10,7-12,2% by weight, and plasticizer therefor, at least 50% by weight of the plasticizer being constituted by normally solid materials.  The ratio of nitrocellulose to plasticizer is within the range 10:5 to 10:15 by weight.  The surface oxidative treatment may be such as to reduce the angle of contact between water and the polypropylene surface to 80 degrees or less, and may consist in heating the surface by means of a flame, corona discharge, or treatment with ozone, chromic acid or mixtures of sulphuric acid and sodium dichromate.  The solid plasticizer may be N-cyclohexyl p-toluene sulphonamide, N-phenyl p-toluene sulphonamide, N-cyclohexyl benzene sulphonamide or dicyclohexyl phthalate, or an aryl-substituted thiourea.  The coating layer may comprise a proportion of a liquid plasticizer. The coating layer may comprise a proportion of resinous material, e.g. rosin, rosin esters, reaction product of rosin and its derivatives with maleic anhydride, natural resins and vinyl polymers containing polar groups, which may be present in proportion less than that of nitrocellulose and the ratio of the combined weight of resinous material and nitrocellulose to plasticizer is within the range 10:5 to 10:15.  The coating layer may comprise an isocyanate compound defined as being compounds containing free isocyanate groups and compounds having isocyanate groups reacted with other compounds containing active hydrogen atoms, e.g. compounds containing hydroxy, carboxy, amino or imino groups, such as water or an aliphatic alcohol.  The coating may be applied as a lacquer prepared by dissolving the constituents of the coating in a solvent, e.g. a mixture of butyl acetate and toluene in the ratio 6:4, and drying off the solvent.

Abstract: 1501279 Counting apparatus TOKYO SHIBAURA ELECTRIC CO Ltd 18 Nov 1975 [18 Nov 1974] 47508/75 Headings G4A and G4D A counting apparatus of the kind comprising a shift register 1-6, built from IGFET's (Fig. 2, not shown), and having feedback to the first stage from the last and one other stage causing it to pass through a long sequence of distinguishable states is provided with means for presetting the individual stages of the register in predetermined states. In Fig. 1 the outputs of the first and last stages are fed back to the input of the first via an exclusive-OR gate 9. An AND-gate 8 is included in the path from the last stage. If the other input a of the AND-gate 8 is held at 1 level the shift register will pass through the maximum of 2n-1 different states. If however the input a is derived by an AND-gate 10 from selected true and inverted outputs of the register stages then a selected number of those is skipped; with the connections shown in Fig. 1 there are 40 states. An input on the SET (S) and RESET (R) lines causes the counter to assume one of those states immediately. The exclusive-OR gate 9 may have its second input from a different one of stages 1-5 (Fig. 9, not shown) or may be replaced by a coincidence gate. Gate 10 may be a NOR gate. In another modification (Fig. 6, not shown) having ten stages but wired to count through 262 states there are additional AND-gates 14 between the first and second and between the sixth and seven states of the shift register these gates both having their other input connected to receive the signal a from gate 10. The shift register circuit employs FET's in a complementary circuit requiring a two phase input; the circuit is dynamic.

The sterilization is preferably carried out by radiation or the addition of a toxic material, e.g. chlorine, ozone, potassium permanganate or sodium carbonate. The activated sludge has been activated by a selected strain of micro-organism which brings about rapid assimilation of oxygen and permits quick settling of the sludge.
