Title: Set forming machine and method
Inventor: NASH ARTHUR JOHN
IPC: B65B35/50
Filed: 1964-07-01
Abstract: 1,117,291. Stacking timber. TIMBER RESEARCH & DEVELOPMENT ASSOCIATION. 1 July, 1965 [1 July, 1964], No. 27229/64. Heading B8C. Timber boards fall from a conveyer 9 to form a series of columns 27, and either the base and abutment at 21 confining the end stack, or the conveyer, is moved after each column has been completed. In the embodiment described, the abutment 21 is carried by a trolley 17 on which the columns are formed. Timber lengths are delivered from a moulder or planer 2 under a fence 3 to the conveyer 6, and while the boards are carried up the conveyer their ends 26 are correctly located by a fair-ender 10. The boards are then aligned by a stop board 13 before they fall on to the end column 14. Completed sets of columns can be discharged on to a roller conveyer where they are battened and banled The movement of the trolleys 17 may be con trolled automatically by a control system 25 which is pre-set in accordance with the width of the board. The set may be formed first to mid-height, and then receive battens perpen dicular to the boards, before completion.

Title: Method for manufacturing integrated circuits
IPC: H01L23/29
Filed: 1973-06-07
Abstract: 1440627 Semi-conductor devices COMMISSARIAT A L'ENERGIE ATOMIQUE 7 June 1973 [15 June 1972] 27250/73 Heading H1K In the manufacture of an integrated circuit a first set of conductors 48-52 is formed on surface areas of a semi-conductor substrate 34, an insulating layer 54 is selectively formed on the remainder of the surface by gaseous deposition and a second set of conductors 56 is formed on the layer 54 making required interconnections between the first set of conductors 48-52. Several methods are disclosed for providing the insulating layer 54 everywhere but over the conductors 48-52. In a first group of these methods the layer 54, preferably of silica, is initially deposited over the entire surface and is then selectively removed from the conductors 48-52, which may be of Al. This selective removal may be effected by etching while vibrating the substrate, the vibration causing preferential etching of the insulation overlying the conductors 48-52. In a third method of this first group, applicable when the conductors 48-52 are of polycrystalline Si or Mo, the conductors 48-52 are covered with P-doped silica prior to application of the overall layer 54. Owing to oxidation of the exposed edges of the Mo conductors during the oxidation process to form the layer 54 the edges swell, distorting the P-doped silica maske so that its edges protrude from the completed layer 54. The structure is then subjected to an etchant which selectively attacks P-doped silica, thus lifting the silica coating free of the Mo conductors. In a second group of methods for forming the insulating layer 54 the material of the layer 54 is prevented from forming over the conductors 48 -52. When the conductors 48-52 are of Mo this may be effected by including in the gas from which the layer 54 is deposited a small amount of HCl gas. This reacts with the Mo to form a volatile compound and the gas thus generated prevents the layer 54 from forming on the Mo. The structure illustrated comprises Si IGFET having a nitride-on-oxide gate insulation.

Abstract: 631,113. Cord-like pesticidal devices. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 11. 1946, No. 27291. Convention date, Sept. 11, 1945. [Class 81 (i)] A pesticidal vapour producing device of cord-like structure, other than a safety fuse cord wherein one or more of the textile yarn coverings around the powder core are coated or impregnated with a thermally vapourisable pesticide compound, comprises a plurality of substantially parallel supporting filaments 1 each adherently coated with an oxygen sufficient combustile powder 2 and confined by a plurality of directly and reversely wound helically disposed and openly spaced strips of binding material 3 and 4, the filaments or binding strips being coated or impregnated with a pesticidal vapour-producing material, while the whole structure is covered with one or more layers of waterproof material 5 and 6. In Fig. 2 (not shown) one of the waterproof layers may be placed around the filaments 1-2. Although the filament and binding strips may be of combustile material such as textile fibres and yarn, paper or thermoplastic material, it is preferred that they should consist at least in part of non-combustile material such as asbestos, glass fibre or fireproofed textile fibres. Specified pesticides are D.D.T., benzene hexachloride, pyrethrum, rotenone bearing materials and nicotine which are distributed throughout the cord in such a manner as to ensure a uniform dispersal of the pesticidal vapour when the cord is ignited. The pesticide may be incorporated with the oxygen sufficient combustile powder by means of a binder consisting of a solution of nitrocellulose, other cellulose esters or ethers, or other combustile plastic or resinous materials. Mealed black powder as des-. cribed in Specification 492,438 and in United States Specification 2,072,720, nitrocellulose or thermite type powders are suitable oxygen sufficient combustile powders. Specifications 524,714 and 541,363 also are referred to. The Specification as open to inspection under Sect. 91 comprises also a structure in which the core consists of the combustile powder in granular or dust form, the pesticide being intimately admixed therewith or forming an annular layer, which is separated from the core by a similar layer of textile material or paper, the whole being surrounded by a textile and then a waterproof covering. This subject-matter does not appear in the Specification as accepted.
