Title: Methods and materials for treating plants
IPC: A61K35/74
Filed: 1973-10-02
Abstract: 1450424 Increasing yields of crops HERSHEY FOODS CORP 2 Oct 1973 [13 Nov 1972 18 Sept 1973] 46001/73 Heading C1B The yield of a wide range of crops may be increased by treating a plant (defined) with active spores of Bacillus uniflagellatus (ATCC No. 15,134) which are defined as those spores which, after germination and growth in root exudate, release an antibiotic substance which is that produced by the procedure described in U.S.A. Specification No. 3,617,448 and which may be assayed by the method disclosed therein. The spores may be commingled with the plant seeds before planting and may be coated with the antibiotic derived from Bacillus uniflagellatus (ATCC No. 15,134) or the leaves of the plant may be sprayed with the active spores, which may be washed into the soil surrounding the plant. The spores may be applied in the form of a dried mixture with the culture medium in which the antibiotic material has been produced, or the spores may be dispersed on a powdered carrier.

Abstract: 1322245 Method and composition for treating flexible substrates DOW CHEMICAL CO 28 Sept 1970 [29 Sept 1969] 46109/70 Heading DIP A process for treating flexible substrates which comprises applying to the substrate a water-in-oil emulsion which contains 1 to 35% by weight water based on the total weight of the emulsion, 98 to 40% by weight of a halogenated hydrocarbon and from 0.2 to 15% by weight of one or more treating chemicals; introducing the wetted substrate into a zone filled with vapours of an halogenated solvent which is at or above the boiling point of the halogenated hydrocarbon employed in the emulsion; maintaining the substrate in said zone until the halogenated hydrocarbon and water are removed from the substrate and withdrawing the substrate from the zone free of water and halogenated hydrocarbon. The halogenated hydrocarbon has a boiling-point between 40 and 165‹C and examples are methylene chloride, chloroform, carbon tetrachloride, 1, 1, 1-trichloroethane, trichloroethylene, perchloroethylene, dibromotetrachloroethane, tetrachlorodifluoroethane, dichlorotetrafluoroethane trichlorotrifluorethane. The substrate may be derived from natural e.g. flax, cotton wool, paper jute and/or synthetic fibres e.g. polyamide, polyester, polyacrylate, or polyacrylonitrile. The treating agents include durable press resins, water repellant resins and chemicals, stain repellant chemicals, fiber stabilization resins, dyes, softeners, lubricants, soil release chemicals, finishing chemicals and fine retardants, e.g. fluoro carbons, silicones, urea aldehyde resins, polyethylenes, polyglycols and inorganic salts.

Concentrated alcohol is obtained at the head of column D. Fusel oil is withdrawn through pipe 12. The liquid leaving the foot of column D is pumped to the head of column A. Alcohol-free slops run out of the foot of column A through pipe 9. The vapours leaving the head of column B flow up column C; and most of the distillate from condenser K 1  is refluxed to column C while the remainder is discharged through pipe 5. The liquid reaching the foot of column C flows through pipe 6 to column B. The production of corn-brandy is referred to.

[Also in Division B6] A machine for forming flanged insulators for electric motor windings comprises adjustably separated rotatable groove-forming discs 12 which co-operate with a driven feed roll 10 having an elastic coating, the feed roll drive also moving a control device 5 between an adjustable cutting length-defining stop 16 and stops for operating electric switches 18, 19 for activating a cutting-off and flanging mechanism. A hand crank 2 is rigid with a pinion wheel 4 for moving a control device rack 5, a sprocket 6 and a chain 7 driving the feed roll 10, in the input direction only, through a freewheeling device. The discs 12 impart a substantially U-shaped section to an input strip 11. The cutting-off and flanging mechanism comprises a movable hold-down device 47 bearing a profile plate 48 co-operable with a fixed knife 51. Stops 27 may be positioned below an upper member 24 by action on levers 28 limiting the stroke of the profile plate 48 to cut-off only, or an end flange may be formed by the full stroke. The mechanism is operated by a traction magnet 26 acting against compression springs 23, and in the cut-off only position, one of the stops 27 operates a pressbutton switch 30, activating the control switch 19. For flanging, with the stops 27 withdrawn, the switch 19 is inactive, and the switch 18 exercises control. For forming plastics strip, the discs 12 may be heated electrically, Fig. 4 (not shown), and the machine is trolley-mounted for mobility, Fig. 6 (not shown).

Abstract: 1,222,407. Rim-forming and perforating. BROWN MACHINE CO. OF MICHIGAN Inc. 2 Oct., 1968 [13 Oct., 1967], No. 46722/68. Heading B5A. A hole is punched in the base of a cold plastics container blank B, and an outwardly extending curled rim formed around the hole, by a reciprocating punch 11 which co-operates with a stationary platen 17 having an opening 18 which receives the reduced leading section 20 of the punch. The blank B is provided with an inwardly-directed stiffening rib 15 and a curved fold section 16. In operation the punch is forwarded into the opening 18 and severs the bottom wall 14 of the blank. Further movement of the punch causes the shoulder 21 on the punch to engage the rib 15 thereby causing the section 16 to be deformed under the axial pressure as shown in Fig. 5. The punch is then withdrawn and the fold section, due to the inherent elasticity of the cold plastics material, partially regains its former shape to form the desired rim. In a second embodiment (see Figs. 8-14, not shown), the stiffening rib is omitted from the blank, the necessary axial pressure being derived by contact of the platen 10 carrying the punch with the web P surrounding the blank.

Title: A process for the conversion of unbranched or sparsely branched olefinic hydrocarbons into saturated hydrocarbons having a branched or more highly branched carbon chain,respectively
IPC: C07C5/13
Filed: 1962-12-24
Abstract: A process for the catalytic conversion of unbranched or "sparsely branched" olefines into saturated hydrocarbons having a branched or more highly branched carbon chain, comprises contacting a starting material containing at least one such olefin at elevated temperature and pressure in the presence of hydrogen or a hydrogen-containing gas with a catalyst which has been prepared by depositing nickel and tungsten on an acid-acting support and converting the nickel and tungsten at least in part to the corresponding sulphides.  Sparsely branched means that the number of branches per molecule does not exceed 2C-7/3 where C is the number of carbon atoms per molecule.  By such a process normal olefins are converted to isoparaffins, e.g. hexene-1 to isohexane.  Acid-acting supports mentioned are SiO2, ZrO2, B2O3, Al2O3, and mixtures. An example describes the hydroisomerization of a hydrocarbon fraction of boiling range 49-185 DEG  C.  Specification 878,035 is referred to.
