Abstract: 1394957 2,2 - (4,4<SP>1</SP> - Dihydroxydiphenyl) propane SOC ITALIANA RESINE SIR SpA 26 Nov 1973 [30 Nov 1972] 54734/73 Heading C2C The invention comprises a process for the preparation of 2,2-(4,41-dihydroxydiphenyl)propane wherein (a) phenol is allowed to react with acetone in a molar ratio of at least 2 : 1 but not exceeding 10 : 1 in the presence of hydrogen chloride or hydrochloric acid as an acidic agent at a temperature not exceeding 80‹ C. to substantially complete reaction of the acetone; (b) the acidic agent is separated from the reaction product; (c) the product freed from hydrogen chloride is brought into contact with activated carbon or active earths at a temperature in the range of from about 60‹ to 120‹ C. for a time in the range of from about 1 to 120 minutes; (d) the product obtained in the treatment with the active material is distilled to recover the 2,2-(4,4<SP>1</SP>-dihydroxydiphenyl) propane. By active earths is meant absorbents prepared from naturally occuring minerals. It is also possible to carry out the reaction in the presence of small quantities, in any case not exceeding about 5% by weight of the bisphenol finally formed, of an aromatic or paraffinic, chlorinated or unchlorinated hydrocarbon organic solvent whose boiling point is below 150‹ C.

Abstract: 1312492 Photo-sensitive materials for producing printing plates MCCALL CORP 18 Nov 1970 [19 Dec 1969] 54761/70 Heading G2C [Also in Division C3] Relief printing plates are made by coating a substrate with the radiation sensitive polymer composition described below, exposing part of the coating to radiation to effect cross-linking  therein, and removing the unexposed part. In example 1, a coating is formed on a metal base, exposed to U. V. light through a lettered stencil, and the unexposed part then removed by methylene chloride. In example 2 the substrate is a metal base having a polyurethane coating thereon, and nine layers of the polymer composition are successively applied thereto, the proportion of photoinitiator in the composition being varied in groups of layers. Example 4 refers to exposure to electron radiation. The polymer composition used above comprises (1) an elastomer containing a plurality of non- terminal ethyleric groups, which is a copolymer of butadiene or a derivative thereof with acrylonitrile or a derivative thereof and which optionally contains carboxyl groups, (2) a saturated halogenated polymer, preferably PVC or a vinyl chloride/vinyl acetate copolymer, (3) a polyfunctional monomeric cross-linking agent (many specified), and (4) a photo-initiator, e.g. benzophenone. The composition is applied from solution, e.g. in methyl ethyl ketone.

Abstract: 1,155,840. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov.25, 1966 [Dec. 24, 1965], No.54859/65. Heading G3R. A battery charging system for a road vehicle comprises a generator 10 connected to charge a battery 14 over lines 12, 13; a voltage sensing circuit including a Zener diode 15 and resistor 16 connected in series directly across the lines 12, 13; a switching circuit including transistors 18, 21, resistors 19, 25 and a capacitor 24 for controlling the current through the field winding 22 of the generator in dependence upon output voltage variations as sensed by the circuit 15, 16; and an ignition switch 17 connected into the circuit as shown. The Zener diode 15 does not conduct at the normal battery voltage, so with switch 17 open only insignificant leakage current flows in the circuit. When switch 17 is closed, and the generator output voltage is below a predetermined value, transistor 21 is rendered conductive and field current flows so that the output voltage builds up to the predetermined value; the Zener diode then conducts to turn on transistor 18 whereby transistor 21 is switched off so that the output voltage falls. The cycle then repeats, the transistors 18, 21 oscillating between their conductive and non-conductive states by virtue of the feedback through capacitor 24 and resistor 25, so that the output voltage is maintained constant.

Also suitable are ethoxylated fatty amines and quaternary ammonium compounds, e.g. lauryl pyridinium chloride or lauryl pyridinium bisulphite. Pigments, e.g. titanium dioxide, aluminium silicate and dyes may be added. The dispersion may be prepared by dissolving the P.E.I. paste in distilled water and introducing the silica aerogel while stirring. High speed stirrers may be used to aid dispersion. Dispersions based on a P.E.I. salt may be obtained by dissolving P.E.I. paste in distilled water, as above, and introducing acetic, formic or phosphoric acids.

Cans 10 having one closed end are fed between the guide rods 62 with their open ends in the trailing position. They are accelerated by jets from nozzles 82 striking the outside surface thereof. Deceleration is produced by jets from nozzles 84 striking the ends of the cans and this continues until the jets from nozzles 82 enter the ends of the cans and the accelerating force overcomes the decelerating force so that the cans leave section T. The jets are fed from a reservoir by a pump through hoses 42, 46 to manifolds 106, 106' each provided with turbulence prevention walls 116, 116'. From section T the cans pass to a section S where they receive a blast of gas from a nozzle 126 which accelerates the cans and removes excess coating material from the outside thereof. In the sections S and T excess material from the coating operation returns via ports 50, 128 to the supply reservoir. Although the apparatus has been described as a coating operation it is of modular construction and the flanged ends 56 of the sections S and T can be joined to other similar sections which instead of coating provide cleaning, rinsing and de-ionizing stages before the cans pass finally to a drying oven. Cleaning materials used include phosphoric or sulphuric acid, carbonates, phosphates, polyphosphates or hydroxides. The coating solution may be a chromate coating solution.
