Title: A new pigment resin printing paste and a method of producing the same
Filed: 1958-04-02
Abstract: An aqueous pigment resin printing paste is produced by acetalizing polyvinyl alcohol or allyl alcohol-modified polyvinyl alcohol with the addition of 0.1 to 0.5 mol. of an unsaturated aldehyde per mol. and then adding a water-dispersible pigment paste and an emulsion of thermoplastic resin and/or thermosetting paste.  An aqueous solution of the acid salt of a polymeric acid amide made from polyacrylic acid ester and ethylene diamine, diethylene triamine, or triethylene tetramine, may be added to the basic paste, this may be produced in the form of a salt by adding acetic or tartaric acid.  The unsaturated aldehyde may be acrolein, metaacrolein, or croton aldehyde and in addition a proportion of one or more saturated aldehydes such as acetaldehyde, propionaldehyde, n-butylaldehyde, isobutylaldehyde, or benzaldehyde may be added.  The paste may be used in aqueous solution or as an oil in water emulsion by emulsifying with a petroleum hydrocarbon.  The colouring matter may be a commercial phthalocyanine paste, Indanthrene Blue-RS, or Threne Red Violet-RH.  Also the resin may have incorporated in it, a vinyl resin such as a polymer or copolymer of vinyl acetate, acrylic acid, meth-acrylic acid ester, acrylonitrile, styrene, vinylidene chloride, butadiene, or polyethylene; or a thermosetting resin such as a formaldehyde condensation product of urea, melamine, modified urea or modified melamine or a ketone resin, such as that obtained by methylolizing methyl ethyl ketone and formalin with the addition of potassium sodium carbonate.

Abstract: 390,642. Two-and four-stroke oil engines. ERLANGSEN, C. F., Camps- Bay, South Africa. April 13, 1932, No. 10592. Convention date, June 17, 1931. [Classes 7 (ii) and 7 (iii).] Pairs of double-ended pistons 3, 4 work on one crank-pin through a common gudgeon 5 and connecting-rod 9. Attached to the bearing 8 for the rod is a pump plunger 11 which compresses air in a small cylinder 12 to ignition temperature. Fuel is injected into this air through the hollow centre of an air admission valve, and burns in the small cylinder, the rise in pressure lifting the spring-pressed head 13 and allowing the rich charge to enter the main cylinders by the ports 16, 17. The lower ends of the pistons supply the main air charge to the combustion chambers in the cylinders 1, 2 ; a cross-connection 39 equalizes the pressure in the pump chambers. The engine may work on the two or four stroke cycle and both ends of each cylinder may act as power chambers; in the latter arrangement a cross-connection is provided to allow equalizing the output.' Pistons, cooling.-The pump plunger 11 is cooled by water from the cooling jackets, the flow being from the telescopic connection 23, 25 through a bore 28 in the gudgeon 5 to a pipe 99 in the interior of the plunger. The water leaves by a second bore 28<1> in the gudgeon and another telescopic connection 24, 26 to the outflow 29.

Abstract: 521,140. Copying-telegraphy local copying by scanning. KREMER, P. Aug. 11, 1938, No. 11242. [Class 40 (iii)] A photographic negative is scanned to produce signals which are modified so as to correct for the non-linear relationship between the density of the negative and the light originally incident thereon. The correction may include the non- linear characteristics of further photographic surfaces. The signals derived from scanning a negative 1 control an oscillograph 9 so that light from a source 12 is modulated by reflection from the screen 15 to correct for the non-linearity of the transparency of the negative and positive relative to the light producing such transparency. Alternatively, the signals may deflect a linear cathode ray beam over a suitably masked fluorescent screen, Fig. 2 (not shown), the light so produced beihg incident on a photo-electric cell to produce signals controlling a Kerr cell. The invention is particularly applicable to the production of colour separation records.
