The products are optical brightening agents. 3,4 - Dichloro - 6 - R- or 6 - H - acetophenones, propiophenones and #-chloro-propiophenones are prepard by Friedel-Crafts acylation.  The sodium salt of 2-sulphostyryl-3<SP>1</SP>,4<SP>1</SP>-dichloro- 6<SP>1</SP>-methyl-phenyl ketone is prepared by reaction of 3,4-dichloro-6-methyl-acetophenone with the sodium salt of benzaldehyde-2-sulphonic acid. 2,4-Dichloro-n-propyl-benzene is prepared by reduction of 2,4-dichloro-propiophenone. The compounds of Formula I are used as optical brighteners for polymers, which may be added before or after polymerization. In an example, an acrylonitrile copolymer containing a brightener is spun from DMF solution.

Title: Improvements in reciprocating pumps
IPC: F04B9/04
Filed: 1946-08-12
Abstract: 636,114. Reciprocating pumps. BOBARD, E. Aug. 12, 1946, Nos. 23826 and 23827. Convention dates, Aug. 20, 1945, and Dec. 20, 1945. [Class 102(i)] In a single acting pump having a rotary driving shaft 5 between two cylinders 1 and 1<SP>1</SP> in which pistons 2 and 2<SP>1</SP> are reciprocated, a valve compartment for admitting and delivering working fluid is arranged between the cylinders and forms with them and the connecting rods a U-shaped unit between the limbs of which the rotary conversion means is also located. Levers 9 and 9<SP>1</SP> pivotally secured at 10 and 10<SP>1</SP> to piston rods 3 and 3<SP>1</SP>, are rocked about a pivot 11 by the rotation of a shaft 5 and a cam 7 which co-operates with rollers 8 and 8<SP>1</SP> carried by the levers 9 and 9<SP>1</SP>. To lubricate the various parts the shaft 5, the cam 7, the pivot 11 and the roller 8 are immersed in an oil bath 12. Since both the outer and inner dead points of each roller 8 and 8<SP>1</SP> do not lie on a diameter passing through the axis of the cam, compensation is provided for variation in output produced during the same revolution of the cam by a difference in the piston strokes obtained through a difference in the length of the levers 9 and 9<SP>1</SP> and/or through an unequal cross section of the cylinders 1 and 1<SP>1</SP>. In addition an arcuate link 19, secured to the levers 9 and 9<SP>1</SP> at 20 and 20<SP>1</SP>, co-operates with a roller 21, Fig. 3, carried by a lever 22 which is adapted to rock about a stationary point 23 to raise and lower the roller 21 and the link 19. When the lever 22 is in the position indicated in Fig. 3 the two rollers 8 and 8<SP>1</SP> remain simultaneously in contact with the cam 7 by the constraining action of the link 19, whilst when the roller 21 is lowered the link 19 restrains the levers 9 and 9<SP>1</SP> in a rigid position spaced outside the field of operation of the cam 7. The pump is adapted to be secured rigidly to a vehicle frame the control shaft coinciding with a wheel shaft for the actu-- ation of the pump.

Title: Alkyd copolymers
IPC: C08F283/01
Filed: 1946-08-16
Abstract: Low pressure laminating compositions are prepared by copolymerizing, e.g. by heating, preferably in the presence of a catalyst, up to 150 DEG  C., an unsaturated alkyd resin with an ester of carbamic acid or an N-alkyl derivative thereof and an alcohol having a double bond between the second and third carbon atoms from the hydroxyl group. The alkyd resins are those obtained by condensing a polyhydric alcohol, e.g. ethylene glycol, diethylene glycol, triethylene glycol, tetramethylene glycol, pentaerythritol, glycerine, trimethylene glycol, thiodiglycol, monoethylin, and 1,2-propylene glycol, with a polycarboxylic acid, e.g. maleic, acetylene dicarboxylic, fumaric, mesaconic, itaconic, aconitic, monochloromaleic, monochlorofumaric, citraconic, alpha-methyl itaconic and alpha-ethyl itaconic acids or their anhydrides, partly replaced by a non-ethylenic polycarboxylic acid, e.g. succinic, phthalic, benzoylphthalic, adipic, sebacic, suberic, and pimelic, up to 75 mol. per cent.  Modifiers may be included, e.g. monohydric alcohols such as propyl, isopropyl, butyl, isobutyl, amyl, isoamyl, allyl, methallyl, crotyl alcohols, monocarboxylic acids such as acetic, propionic, butyric, benzoic, acrylic, methacrylic acids and drying or semi-drying oils, e.g. tung, soya, castor and linseed.  The carbamates have the general formula RR1NCO2R11, R and R1 being H or alkyl and R11 being the residue of the unsaturated alcohol, e.g. allyl, 3-chloro-allyl, methallyl, crotyl, a -ethyl allyl, b -ethyl allyl, 2-chloro-allyl, tiglyl or b -propyl-allyl alcohol. Catalysts for the copolymerization are benzoyl peroxide, hydrogen peroxide, ammonium persulphate, sodium perborate, barium peroxide, sodium peroxide, acetyl peroxide, lauroyl peroxide or stearyl peroxide.  In the example, diethylene glycol and maleic anhydride were condensed to an alkyd resin which was mixed with allyl carbamate containing dissolved benzoyl peroxide.  A multi-ply structure of glass cloth was impregnated with the mixture, was enveloped in "Cellophane" (Registered Trade Mark), pressed between glass sheets and heated to 80 DEG  C.  The mixture was also polymerized in a mould to form a clear sheet.  The products are insoluble in common organic solvents and resistant to acids and alkalis.  The mixture to be polymerized may include fillers, e.g. carbon black, textile flocs, e.g. cotton, rayon, silk, nylon, wool, or hemp, dyes, plasticizers, pigments and resins.

Abstract: Vaccines and remedies to be administered parenterally or per os. are prepared by causing apathogenic bacteria which produce albumendigestive ferments to act on a suspension of pathogenic bacteria in an albumen-free solution serving as a culture medium for the ferment-producing bacteria but not for the pathogenic bacteria. After dissolution of the pathogenic bacteria has taken place the suspension is centrifuged to remove solid particles and sterilized by filtration.  Pathogenic bacteria specified are those of the coli, typhoid, dysentery group, cholera and pest bacilli, staphylococci, and abortion bacilli.  The ferment-producing bacteria used are those of the subtilis, mesentericus and mycoides groups.  The media used according to the examples are aqueous solutions of asparagine or the sodium salt of aspartic acid, or ammonium lactate, or both, together with sodium and potassium phosphates, and one or more of the following salts, viz.: magnesium sulphate, sodium chloride, and calcium chloride. The medium is adjusted to a pH between 7 and 8 or more.  The final products yield a negative biuret reaction.  The Specification as open to inspection under Sect. 91 refers also to dissolution of the pathogenic bacteria by means of bacterial, animal or vegetable ferments, of which a large number examples are given and includes additional specific examples of the process, according to which a mass of bacilli, or a virus, such as that of swine fever, enriched by ultra filtration, is mixed with water, heated to 80 DEG C., cooled, and digested with pancreatine in alkaline solution, or with papayotin in acid solution; the resultant solution being allowed to stand for several hours after adjustment to pH 4.0 or 4.6, then neutralized with sodium carbonate or hydrate, and finally sterilized by filtration.  This subject-matter does not appear in the Specification as accepted.
