Title: Foliar sprays and methods of application thereof
IPC: C05D9/02
Filed: 1970-04-16
Abstract: 1,268,308. Foliar sprays. ITT INDUSTRIES Inc. 16 April, 1970 [23 April, 1969], No. 18197/70. Heading C1B. Foliar sprays for overcoming iron deficiency in iron chlorotic evergreen trees, e.g. citrus trees, Mexican and Guatemalan avocado trees and coffee bean trees, comprise water-soluble compounds which are non-toxic to the trees and are selected from the group consisting of polyols, ethers thereof and mixtures thereof, e.g. glycerol, ethylene glycol, propylene glycol, dipropylene glycol, triethyleneglycol, 1,3-butanediol, polypropylene glycol with an average molecular weight of around 425, pentaerythritol, sorbitol, mannitol, α-methyl-D-glucoside, α-methyl-D- mannoside, polyethylene glycols with up to 28 carbon atoms and mixtures thereof in conjunction with organic iron sources in the form of ferrous complexes of sulphomethylated conifer barks, ferrous and ferric salts of hydroxy acids or salts thereof, the hydroxy acids being, for example, gluconic acid, glucoheptonic acid, mixed gluconic and idonic acids, glucosaccharic acid, tartaric acid, citric acid, mannoheptonic acid, isosaccharinic acid. The non-toxic watersoluble compounds are present in amounts from 0À3% to 4% by weight of the spray solution and the organic iron sources are present in an amount sufficient to provide concentrations from 0À5 to 6À0 pounds of iron per 100 gallons of spray solution. The sprays may also contain lowbiuret urea in an amount ranging from 2À5 to 10 pounds per 100 gallons of spray solution. A spreader, e.g. sodium dioctyl sulphosuccinate, and a sticker may be included in the sprays. The sprays eliminate iron deficiency in the trees by penetrating the waxy surface of the leaves of the trees, thus allowing the iron in the spray to permeate throughout the iron-deficient area of the leaves.

Title: Improvements in or relating to the heat treatment of lightmetal alloys containing magnesium
IPC: C22F1/047
Filed: 1936-07-01
Abstract: The bath for use in the heat-treatment of light alloys containing magnesium described in the parent Specification has a content of monochromate such that the ratio of monochromate to dichromate lies between the equilibrium ratio set up between dichromate and monochromate at the temperatures (350-595 DEG  C.) at which the bath is to be used and the ratio at which the bath ceases to be in a completely fused condition.  The requisite amount of monochromate may be added to the bath or may be formed in the bath by the addition of substances such as caustic alkalies, or alkali metal peroxides, nitrates and carbonates which are adapted to convert part of the dichromate into monochromate.

Title: Improvements in or relating to refrigeration systems
IPC: F25B15/06
Filed: 1947-07-10
Abstract: 639,417. Refrigerating. CARRIER ENGINEERING CO., Ltd. July 10, 1947, No. 18380. Convention date, Aug. 22, 1946. [Class 29] The refrigerating system described in Specifications 639,413 and 639,416, is modified in that the flow of cooling water through the condenser 7 is controlled by means responsive to the saturation temperature due to the pressure in the shell 5 containing the generator and condenser. A proportion of the generated vapours is withdrawn from the condenser 7 through a pipe 37 to a casing 36 where the vapours condense and are maintained at a constant level by a pipe 43 leading to the purging device 33. Within the casing 36 is the bulb 38 of a thermostatic device 44 which controls a valve 34 in the condenser cooling water pipe 26. The bulb 38 is covered with a wick and dips into the condensate in the casing 36. As the presure varies in the shell 5, the temperature of the bulb 38 is varied by the wet wick, thus altering the flow of cooling water to the condenser.

Abstract: 146,491. Forest, L. de. April 17, 1919, [Convention date]. Drawings to Specification. Telephone systems; thermonic repeaters.-The metallic sheaths of existing submarine telegraph cables are used for telephonic communication, being earthed at points some distance from their ends through thermionic valve transmitting and receiving apparatus. A second cable may be employed as a return, or the earth connexion at each end of the cable may be made to a stratum of greater conductivity than neighbouring strata. At the transmitting station the oscillations of a microphone circuit may be communicated to the line through an amplifying cascade comprising for example one 50-watt valve, one-half-kilowatt valve, and three 2-kilowatt valves, giving an audio-frequency output current of 5 to 10 kilowatts. The fraction of this current detected at the receiving station is amplified by means of audions. Specifications 2059/14 and 145,476 are referred to. According to the Specification as open to inspection under Sect. 91 (3) (a), the core of the cable may be used instead of the sheath. This subjectmatter does not appear in the Specification as accepted.
