Title: Process for the production of means for the combating of vegetable diseases and of vegetable and animal organisms deleterious to plants
IPC: A01N65/22
Filed: 1930-11-20
Abstract: Preparations for protecting plants against insects and fungoid diseases consist of an extract or decoction of a plant yielding insecticidal or fungicidal products together with copper benzoate or with a substance obtained by boiling an unsaturated or etherial oil with sulphur.  It is stated that the insoluble chemicals deposited from these compositions are non-injurious to the plant but react to produce active substances in an acid environment produced by the growth of moulds.  Sulphuretted oils may be added as such, or formed by boiling the plant extract with sulphur if it already contains an unsaturated oil such as poppy oil, citronella oil, or oil of lavender.  Substances of a slimy nature, such as gelatine, gum, latex, and mucilage of Irish moss, or finely powdered substances such as talcum lycopodium and pine dust, may also be added.  According to examples (1) a decoction of madder root is mixed with myrrh, benzoate of copper and gelatine; (2) a decoction of ratanhia root is mixed with camphor, sulphuretted linseed oil, talcum, and gum arabic; (3) an aqueous extract of salvia officinalis which contains etherial oils is boiled with sulphur under reflux; copper benzoate and gum may be added.  Each of these preparations is diluted with water for use. Specifications 8081/05, [Class 81, Medicine &c.], and 189,037, [Class 81 (i), Disinfecting &c.], are referred to. p  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use alone, or with the additions above referred to, of aqueous extracts or distillates prepared from any plant which is immune from attack by the insect or disease to be treated, and states that solid particles of such plants may be allowed to remain in the liquid preparations. Examples refer to aqueous extract of indigo, extract of ratanhia, suspensions of indigo containing soap, and a soapy emulsion of distilled oil of rosemary.  Insoluble metal salts of vegetable acids may be formed in the aqueous preparations by adding oxides, hydrates or carbonates of metals such as copper which combine with vegetable acids, naturally present in the extracts or added thereto, such as benzoic acid, benzoin, salicylic acid, formic acid, and annomic acid; or insoluble metal compounds may be added in the absence of acid; or the vegetable acid salts may be added as such.  Finely powdered substances to be added include sulphur, preferably in the form of milk of sulphur, indigo powder and naphthalene. Preparations containing arsenious oxide are also referred to.  The preparations may be sprayed on the plants or evaporated, or may be spread on paper impregnated with saltpetre and used as fumigants. This subject-matter does not appear in the Specification as accepted.

Title: Photographic exposure meter scale system
IPC: G01J1/40
Filed: 1929-11-15
Abstract: 348,662. Photographic exposuremeters. BING, J. M., 152, West 42nd Street, New York, U.S.A. Nov. 15, 1929, No. 34995. Convention date, Aug. 9. [Class 98 (i).] A scale arrangement for an exposure meter comprises (1) a movable member 3, Fig. 2, having a lens diaphragm scale and an emulsion-speed scale longitudinally thereon, (2) a fixed member 2 having a fixed standard index 6 adjacent the emulsionspeed scale 6, and (3) a movable element 5a which is set in accordance with light conditions and has a pointer 5 moving directly or indirectly over the diaphragm scale. This arrangement, without an additional adjustable exposure time scale 4, indicates the lens diaphragm for a definite exposure time of a plate whose characteristics (e.g. PAR: or Extra Rapid) are known. For kinematograph purposes the scale-markings may be modified. The above arrangement is more especially for photometers such as described in U.S. Reissue Patent 16879 and U.S. Patent 1,733,354 in which the light conditions are determined by adjusting the diaphragm in the viewing aperture so as to render visible numerals or symbols on a selected field having an opacity corresponding to an exposure time for a standard plate. Reference is also made to Specification 214,939, [Class 98 (i), Photographic cameras &c.]. The scales may be arranged as rings 2, 3, 4, Fig. 1, on the photometer 1. As shown in Fig. 2, the pointer 5 moves over a series of lines 7 on the fixed member 2 which have equal spacings on the edge adjacent the diaphragm scale. The index 6 on the member 2 may be one marking of a filter factor scale. The exposure time scale 4, when used, is preliminarily set so that the exposure time (e.g. <1>/25 sec.) corresponding to the selected light field of the photometer is opposite the diaphragm reading (e.g. F. 8) indicated by the pointer 5. For kinematograph work taking-speed markings can be substituted for the plate speed markings ; shutter blade openings for the time exposure scale ; and markings on the diaphragm scale to indicate the existence of conditions for colour kinematography and the use of a special filter (e.g. a neutral density filter).

[Also in Division A5] An innocuous surgical sewing thread is produced by coating a clean dry thread, e.g. nylon with a hydrophilic polymer (i.e. one which when in equilibrium with water contains from 20-80% by volume water) of "glycerol" or "glycol" mono-methacrylate or mono-acrylate (where glycerol means glycerine, mannitol or pentaerythritol and glycol means any watersoluble aliphatic diol such as ethylene glycol, diethylene glycol, and ethylene glycol-propylene glycol co-polycondensates). The polymer may contain a minor amount of glycerol or glycol dimethacrylate or diacrylate as a crosslinking agent. The coating may be produced either by cross-linking a monomer mixture directly onto the thread, or by applying a solution of a soluble non-crosslinked polymer and subsequently evaporating the solvent and, if desired, cross-linking. A biologically active substance, i.e. antiseptic, antibiotic, antibacterial &c. may be incorporated into the thread in various ways depending upon the desired rate at which the substance is to be liberated, e.g. the drug may be imbibed in a solution by the untreated thread which is subsequently coated or the drug may be added to the monomer mixture prior to polymerisation, or the finished and sterilised thread may be immersed in a solution of the drug. Polyamide threads may be coated in this way.
