Patent GB-1052214-A (GB)
Abstract: 1,052,214. Preparing bis-(2-hydroxy-2-carboxyethyl) disulphide and salts thereof. STAMICARBON N.V. Aug. 9, 1963 [Aug. 9, 1962], No. 31589/63. Heading C2C. An alkali metal or alkaline earth metal salt of bis-(2-hydroxy-2-carboxyethyl) disulphide is obtained by contacting a salt of epoxyethane carboxylic acid (glycidic acid) in aqueous solution with a water-soluble alkali metal disulphide or an alkaline earth metal disulphide, e.g. calcium disulphide. The metal salt product can be converted to the free (acid) disulphide or to another salt, e.g. the sodium salt can be converted to the free acid by treatment with sulphuric acid and the calcium salt may then be formed by treating the free acid, or soluble salt thereof, e.g. the sodium salt, with calcium carbonate or calcium hydroxide. The free acid can be extracted from the aqueous reaction mixture with a solvent, e.g. pentanol-1. The salt of the epoxyethane carboxylic acid used as starting material may be obtained in situ from the free acid by using an excess of the inorganic disulphide. The process is preferably carried out by adding a solution of sodium disulphide to a solution of sodium epoxyethane carboxylate or by adding a solution of the latter to a solution of sodium disulphide, carbon dioxide being preferably passed through the solution in each case to maintain the pH at between 8À5 and 10.

Abstract: 1,053,036. Seed pellets. GERMAIN'S Inc. May 21, 1965 [Sept. 21, 1964], No. 21722/65. Heading A2Q. A seed pellet comprises a viable seed, e.g. a monogerm sugar-beet seed, coated with a plurality of superimposed layers, one of which is spaced from the seed, as by a barrier layer of activated carbon, and contains sufficient systemic insecticide or pesticide to protect the future plant from attack by pests and insects such as maggots, symphylans and leaf-hoppers. (The latter spread the virus disease "curly top" among sugar-beet leaves). The seed pellet also comprises at least one other layer containing a hygroscopic substance such as sub-bentonite clay, which also functions as an adhesive. The seed pellet may comprise a seed coated with an inner layer of a hygroscopic substance and/or activated carbon, and an outer layer of systemic insecticide mixed with a hygroscopic substance. The seed pellet preferably comprises an outermost layer or envelope, e.g. of sub-bentonite clay, to protect operatives from the systemic insecticide or pesticide. Seed pellets made according to the invention are preferably uniform in size and shape, to facilitate mechanical drilling. Specified systemic insecticides and pesticides are: O, O, diethyl S-(ethylthiomethyl) phosphorodithioate, O, O-diethyl O (and S)- 2-(ethylthio) ethyl phosphorothioates, and O, O-diethyl S-2 (ethylthio) ethyl phosphorodithioate, between 0.25 and 8.0 ounces of which may be present in the coatings of each two pounds of seeds, and O, O-dimethyl S-2-(ethyl sulphinyl) ethyl phosphorothioate, O, O-diethyl O-2-pyrazinyl phosphorothioate O-2, 4-dichlorophenyl O, O-diethyl phosphorothioate, and aldrin, between 0.5 and 16.0 ounces of which may be present in the coatings of each two pounds of seeds. The application of an accurately measured quantity of a systemic insecticide or pesticide to the root and sap systems of a newly germinated seedling, is facilitated when a seed, coated according to the invention, is planted in soil under conditions favouring hygroscopic disruption of the coatings, and subsequent germination of the seed.

Abstract: 1,239,443. Telegraphy. DATAMAX CORP. 5 June, 1968, No. 26669/68. Heading H4P. In an error correcting digital data transmission system, each data bit on an input line 12 is passed direct to a transmission line 32, and is immediately followed by two check bits derived, by a shift register 14 and two modulo 2 adders 22, 24, from the current data bit and the preceding four data bits, and at the receiver, the received bits (data bits interleaved with pairs of check bits) are entered into a shift register 38, the entire contents of the register are examined 50, after each data bit and its associated check bits have been received, to decide whether the data bit in position 15 of the register is more likely to have originated from a " 1 " bit or from a " 0 " bit at the input 12 to the transmitter, and as a result of the decision, firstly an output data bit is fed to a line 36 (these should be the same as the input data bits) and secondly every time a " 1 " bit is decided upon, certain stages of the register 38 are reversed. The required decision is made by comparing the fifteen bits in the register 38 with each row of a table, Fig. 4, the comparison with each row being quantified by counting one for every agreeing bit position, and by deciding whether the best match lies in the upper (giving a " 0 " output) or in the lower (giving a " 1 " output) half of the table. Four methods of effecting the comparisons are described. In a first method, a red/blue transparent mask 62, Fig. 3, is made corresponding to the tables of Fig. 4, vertical columns of red (="1") and blue (= " 0 ") light are shone at the mask by lenses 70 in accordance with the contents of the register, and rows of photo-electric detectors 64, equally responsive to red and blue light are arranged so as to receive light from the individual rows of the mask, whereupon the amplitude of the signal produced by each detector will represent the degree of match between the contents of the register and the corresponding row of the matrix. In a second embodiment (Fig. 7, not shown), the mask is used in combination with a colour C.R.T. and a T.V. camera. In a third embodiment (Fig. 8, not shown), the table of Fig. 4 is represented by a diode matrix, and in a fourth embodiment (Fig. 9, not shown) the rows of the table of Fig. 4 are successively generated by a five-stage counter and compared with the contents of the register. The system is said to be tolerant to transmission errors but no theory or reasons are given.

Abstract: 1,251,569. Toy gun. LOUIS MARX & CO. Ltd. 28 Nov., 1969, No. 58368/69. Heading A6S. A toy gun apparatus which can fire either a single shot (slow-fire) or several projectiles one after the other without interruption (rapidfire) upon a single actuation of a trigger 36, comprises a supply duct 64 passing to a rotary impeller 74. The trigger is connected via a strip 100 to two projections 102, 104 offset with respect to one another and which can project into the supply duct, a selector means co-acting with the trigger for controlling the extent to which the projections project into the supply duct. For slow-fire one projection is moved out of the supply duct while the other projection is forced into the duct, one projectile being released, the other projectiles being blocked; upon release of the trigger a further projectile is allowed to position itself over the lower projection. For rapid-fire the higher projection is deflected to a position whereby upon actuation of the trigger this projection is not moved into the duct thereby not blocking the passage of projectiles. The selector means may be moved to an "off" position where depression of the trigger is prevented.
