Abstract: 548,630. Coating with metals; spray-producers. BLOUNT, B. D. H., and BALLARD, W. E. March 11, 1941, Nos. 3276 and 14090. [Class 82 (ii)] [Also in Groups XXIX] In the coating with metals by spraying, the metal is passed from the spraying device through an external tubular shield, a liquid or gaseous reagent such as an inert or reducing gas being admitted to the interior of the shield for the purpose of controlling the properties of the metal coatings. When spraying such metals as copper or copper alloys, paraffin oil is introduced into the interior of the shield which is cooled by a jacket containing liquid, e.g. water, acetone, liquid air or ethylene glycol, which is circulated therethrough and when spraying other metals, such as steel the shield is heat insulated and superheated steam is injected into the shield. In the apparatus shown in Fig. 1, the part 12 of the conical shield 11 is secured to the nozzle 10 of the spraying device the joint being made by heat-insulating material 13. An inlet pipe 14 for the introduction of an inert, reducing or combustible gas is provided.

Title: Marking process and apparatus for elongated bodies

IPC: H01B13/34
Filed: 1970-01-23
Abstract: 1275714 Wire marking apparatus J C GEMELLI 23 Jan 1970 [27 Jan 1969] 3471/70 Heading D1L An elongated body, e.g. an insulated wire, is marked with coloured bands by ink in the form of streams from one or more nozzles, these streams being perpendicular to the longitudinal axis of the body (along which axis the body moves) and the body and the nozzles being in relative oscillation so that a stream of ink, which should not have deteriorated into a spray of droplets when it reaches the body, will pass across the width of the body, the surface tension of the ink causing it to encircle the body to form a band. In the embodiment shown there are two nozzles 30 and 32 fed from a container 50 via a positive action pump 46, a pipe and a T junction 50. The nozzles are here oscillated by movement of member 36, the rates of oscillation, advancement of the wire 14 and the spacing of the nozzles being variable. Ink not deposited on the wire is caught in a hood 62 and returns to the ink reservoir 50 via sump 64 and pipe 66. Two or more colours can be applied at once by duplication of the apparatus and taking care not to mix the ink streams (e.g. by having these streams in different directions, two hoods &c.). A warning device in the form of an alarm 70 and/or a pressure gauge 68 is fitted to inform of either an unwanted increase in viscosity of the ink or a blocked nozzle. The by-pass pipe 72 and taps 74 and 76 are used to flush the bulk of the system when the ink is changed, the ink being pumped directly into sump 64.

Class 97(1) To enable a miscroscope illumination system to be adjusted for objectives of differing focal length the elements of the condenser proper are fixed and further lenses are provided movable into the system at different planes between the illumination-field diaphgragm and the condenser proper so that an image of the light source is always formed at the aperture diaphragm of the condenser and an image of the illumination field diaphragm is formed at the object. Fig. 2b shows a system in which the fixed condenser lenses 1, 2, 3, 4, 5 alone give maximum aperture and a small field. To decrease the former and increase the latter a telescope 9, 10 and 11 is introduced between the field diaphragh L and the lenses 3, 4 and 5, the lens 9 forming an intermediate image of the diaphragm. To give further step-bystep changes in aperture and field the lens 10 may be omitted, the lens 9 being suitably adjusted in position, and then so adjusted on further change may be effected by replacing the negative lens 11 by another negative lens, and a further change by omitting the lens 11. Further examples are given for systems in which the fixed condenser elements alone give medium aperture and field and in which they give small aperture and maximum field, the necessary changes being effected by the insertion of suitable lenses.

Abstract: 1468261 Nuclear fuel UNITED KINGDOM ATOMIC ENERGY AUTHORITY 13 Jan 1975 [25 Jan 1974] 03644/74 Heading G6C A nuclear fuel particle contains fissile and fertile material separated by an internal barrier. As shown, the particle comprises a kernel 4 of fissile material covered by a barrier coating 3 of silicon carbide 3b sandwiched between two pyrocarbon layers 3a, 3c, a coating 5 of fertile material, and an outer fission product retaining coating 6 similar to the coating 3. The fissile material may be an oxide or carbide of U 235, U 233, or Pu 239, and the fertile material an oxide or carbide of Th 232 or U 238. The fissile kernels and the fertile coating 5 may be made porous by mixing the fuel or fertile material with stearic acid binder and then heating to remove the binder. The layers of pyrocarbon and silicon carbide may be applied in a fluidized bed process. The coated particles may be mixed with graphite and resin and pressed into shaped bodies. After use in a nuclear reactor, the particles may be separated from the shaped bodies, crushed to fracture the outer coatings, and the fertile material dissolved out from the coated fissile material.
