Title: Improvements in and relating to monoethers of araliphatic glycols
Filed: 1951-11-26
Abstract: The invention comprises novel mono-ethers of 1 : 1 - bis - (41 - chlorophenyl) - ethylene glycol of the general formula: <FORM:0709658/IV (b)/1> wherein R represents an alkyl radical containing from one to six carbon atoms, or an alkenyl radical containing up to three carbon atoms; also a process for their preparation, whereby an ester of an etherified hydroxyacetic acid is reacted with two molecules of 4-chlorophenyl magnesium bromide or iodide.  A modification of this process, wherein the nitrile of an etherified hydroxy acetic acid is reacted at first with one molecule of the Grignard reagent to produce an etherified hydroxymethyl p-chlorophenyl ketone, which is then treated with a further molecule of the reagent, is also described.  In examples: (1) ethereal p-chloro-bromobenzene and magnesium are reacted with ethyl ethoxy acetate to yield 1 : 1 - bis - (41 - chlorophenyl) - 2 - ethoxy ethanol.  Methyl, n-propyl, iso-propyl, n-butyl, allyl and n-hexyl ethers are also mentioned; (2) ethereal ethoxy acetonitrile, magnesium and p-chloro-bromobenzene are interacted and o -ethoxy-p-chloro-acetophenone isolated; upon further reaction with the Grignard reagent 1 : 1-bis-(41-chlorophenyl)-2-ethoxy ethanol is obtained.ALSO:Novel mono-ethers of 1 : 1-bis-(41-chlorophenyl)-ethylene glycol of general formula:- <FORM:0709658/VI/1> wherein R represents an alkyl radical containing from one to six carbon atoms, or an alkenyl radical containing up to three carbon atoms, (see Group IV(b)), are incorporated in pesticidal compositions, which may also include (a) a carrier or diluent consisting of a pulverulent solid, e.g. talc, bentonite, kaolin, precipitated magnesia, bole, boric acid, whiting, tri-calcium phosphate, powdered wood or cork; or an inert organic liquid, e.g. mineral oils, xylene, diacetone alcohol, petroleum; (b) a wetting, emulsifying or dispersion agent, e.g. the sodium salt of dibutyl naphthalene sulphonic acid, sulphite waste liquor, ethylene oxide condensates, soaps; (c) other bactericidal, fungicidal or pesticidal agents, e.g. benzyl benzoate, dimethyl thianthrene, phthalonitrile, dinitrocresol, dichloro-diphenyl-trichlorethane, 1-phenyl-3-methyl-pyrazolyl-(5)-dimethyl carbamate, 5:5-dimethyl - dihydro - resorcinol dimethyl carbamate.

IPC: G06G1/00
Filed: 1954-09-27
Abstract: 815,464. Calculating-apparatus. BOYCE, J. L., and MEANWELL, A. Sept. 22, 1955 [Sept. 27, 1954], No. 27781/54. Class 106 (1). A logarithmic calculator, for use in the bending of metal sheet and strip, is provided with scales enabling the developed length D of the arc of bend and the distance P (see Fig. 4) to be obtained according to the formulµ D = 0.01745 x # x (R + kT), and P = (R + T) X tan #/2, k having the constant value 0.445.

Title: Improvements in or relating to spring transmission or coupling elements for use in training or elevating guns
IPC: F41A27/06
Filed: 1939-04-03
Abstract: 577,851. Aiming guns. JAPOLSKY, N. April 3, 1939, No. 27787. Divided out of 577,849, [Group XXXVIII]. [Class 92 (i)] [Also in Group XXIV] Relates to means enabling adjustments in elevation and training to be continuously transmitted to guns notwithstanding increases. in resistance due to firing, of the kind in which spring couplings are provided in the transmission, the springs being of such strength that they yield only when the increase in resistance occurs, thereby storing up the movement for subsequent transmission to the driven member. According to the invention, the coupling comprises two members acting on either side of an intermediate member, two of the members being coaxially rotatable relatively to each other and to the third. Further, the normal relative position of the first two members tends to be maintained by spring means acting through the intermediate member so that after mutual displacement the various members assume their original positions. Fig. 2 shows the invention applied between a shaft 18 driven by an elevation receiver and a shaft 19 for elevating the gun. The drive normally takes place through a differential gear 15, the planetary pinions of which are carried by a shaft 17 that remains fixed. The shaft 17 carries a sleeve 20 with a helical groove 21 in which moves a key 22 feathered on a drum 25 having a helical groove 27 in which moves a key 28 feathered on the external casing 14. Clock springs 32, 30 are arranged between the fixed casing and the drum 25 and between the drum and a collar 31 fixed to the shaft 17. When a depression adjustment occurs during firing, the planetary pinions rotate the shaft 17, the key 22 jams at the end of the groove 21, and the drum 25 is turned to wind the spring 32. The spring 30 is meanwhile prevented from tensioning by the sliding of the key 28. When elevation occurs during firing, the spring 30 is tensioned and the spring 32 rendered inactive. A modification suitable for embodiment in the training drive is described in which the differential gear is dispensed with, a single clock spring being stressed from each end in turn for training adjustment in either direction. Specification 577,849 is referred to

Title: Hydroprocessing of grain
IPC: B02B3/12
Filed: 1972-06-16
Abstract: 1357669 Processing cereal grain PILLSBURY CO 16 June 1972 [18 June 1971] 28209/72 Heading A2Q A method of processing wheat, rye or oats to separate the endosperm from the husk and germ tissues comprises the steps of steeping the grain in an aqueous acid medium, macerating the steeped grain to split the husk and expose the endosperm as a plastic mass, dispersing the macerated grain in an aqueous medium with sufficient shear to disengage the endosperm from the husk and germ tissues, and separating the dispersion so obtained into a particulate husk and germ fraction and an endosperm dispersion. Throughout the process, which may be conducted on a continuous or batch basis, substantially all of the starch granules are maintained in an intact, ungelatinized form and substantially all of the gluten protein is maintained in a dispersible and substantially undenatured state with respect to doughing function. The aqueous steeping medium contains one or more dissociated edible acids, e.g. hydrochloric, sulphuric, phosphoric, lactic, in a concentration sufficient to maintain the pH of the medium external to the grain between 0.8 and 2.5 and to reduce the internal pH of the steeped grain from an initial 5.8 to between 2.5 and 4.0. Steeping with agitation, e.g. in a tower or silo, is carried out in at least 1.5 parts by weight of steeping medium to 1 part of grain at temperatures in the range 18‹ to 45‹C until the grain has taken up steeping medium in an amount equivalent to 56 to 95% of its weight. Air in the grain may be eliminated by a vacuum or carbon dioxide treatment. After the steeping the grain is drained and then macerated in an apparatus in which it is squeezed, crushed or rubbed to effect an initial breakdown between the endosperm and the husk and germ portions. The grain is next dispersed in a medium, similar to the steeping medium and maintained at a pH between 2.4 and 3.4, with sufficient shear, e.g. using a centrifugal pump, to disengage the endosperm from the non-endosperm material, dispersing the endosperm as particles of less than 300 microns in size while maintaining at least 90% by weight of the non-endosperm material above a minimum dimension of 300 microns. The next step consists of screening processes to separate the endosperm and non- endosperm material, although this step may be combined with the dispersion step. The separated endosperm may be incorporated directly into a dough or subjected to spray drying . Before drying the endosperm may be activated by adjustment of its pH value to between 4.5 and 6.5 with, e.g. hydroxide of potassium, calcium or sodium, and treated with oxidizing agents such as bromate, iodate and persulphate salts, peroxides, and oxygen, and/or thiolytic reducing agents.
