Abstract: 428,891. Two - stroke compressionignition engines ; ports. BONACOSSA, L., 16, Via Bramante, Milan, Italy. May 5, 1934, No. 13636. [Class 7 (ii)] The movable cylinder head 1 remains stationary until the main piston 12 uncovers terminal exhaust ports, then recedes to uncover two sets of scavenging ports 10, 11, and keeps them uncovered until the main piston recovers the exhaust ports. During the compression stroke of the main piston, the head 1 covers the ports 10 but leaves open the ports 11 for supercharging purposes ; covers the ports 11 before fuel is injected and combustion starts and then moves at the same speed and in the same direction as the main piston, maintaining a constant volume for the combustion space during the combustion period. The cylinder heads are actuated by overhead cams, or from cams on the crankshaft through linkwork. The ports 10 are tapered outwardly and upwardly inclined towards the cylinder, of rectangular cross-section, and radial to the cylinder 11. The ports 11 are tapered inwardly, and downwardly inclined, of circular crosssection, and oblique to the cylinder radii.

Class 123(1) [Also in Group XXXVII] Means for indicating an abnormally low level of oil in, for example, the sump of a motor vehicle comprises a small internal diameter tube or probe 1. Fig. 1, which is fixed relatively to the sump and is provided with openings 3 at the minimum desirable oil level 4. The upper end of the probe terminates in an enlarged chamber 13 which is connected to a valve-less air suction pump 8 by small bore tubing 11, the latter having a branch 16 leading to an electric switch 14 which controls a signal lamp 17 and is responsive to air pressure so that its contacts close only when the pressure in. the branch is less than atmospheric, that is when the oil level is above the openings 3. In a modification, not shown, the probe 1 is fitted with an orifice-type restriction or a liquid-only non-return valve to check any withdrawal of oil by the pump 8, and the switch 14 may be incorporated in the circuits of the oil pressure or ignition warning lamps. In a further arrangement the pump 8 is dispensed with and the tubing 11, Fig. 3, with its branch 16, is connected by a capillary tube 24 to the induction manifold 23 of the vehicle engine, the other end of the tubing 11 communicating with the probe 1, having a restriction 18, through an oil trap and overflow chamber 13, a liquid-only non-return valve 25, and an oil delay chamber 26.

Patent GB-972094-A (GB)
Title: Improvements relating to phenol-aldehyde resins
Inventor: NEALE ALBERT EDWARD TONEY
IPC: C08G2/00
Filed: 1960-04-22
Abstract: A phenol-aldehyde resin is prepared by reacting a phenol and a polyacrolein of molecular weight of at least 5000, preferably 15,000 to 60,000, dissolved sulphurous acid solution. Condensation is preferably under acid or substantially neutral conditions.  The polyacrolein may have substituent groups e.g. halogen atoms or alkyl groups as in polymethacrolein. Copolymers of acrolein with other vinyl monomers may be employed. Addition products of the polymers may be used provided they retain their predominantly aldehydic character. Initial condensates may be water-soluble, suitable for coating or impregnating compositions since on drying they yield flexible, water-insoluble materials.  They are also useful as adhesives or tanning agents. The resistance to swelling or water of the dried products may be increased by heat treatment at 45 DEG -100 DEG C., by use of acid or latent acid catalysts, or by chemical after-treatment, e.g. with aldehyde-reaction reagents, such as polymers containing hydroxy, amino or sulphydryl groups, organic bases or their derivatives, glycols and diamines. Rigid foams may be formed by heating the sulphurous acid solution of polyacrolein with phenol e.g. at 80 DEG C., to form a gel which is then heated at higher temperature, e.g. 120 DEG C. Addition of wood flour improves the foams. Forming them in smooth moulds yields foams with a hard polished surface. In Examples I, II, sulphur dioxide was passed into a 16% mixture of polyacrolein (Mol. wt. 30,000) and water.  Nitrogen was blown through the solution to remove excess sulphur dioxide, and the solution was mixed with phenol and hydrochloric acid, and heated at 55-60 DEG C. for 1 to 2 hours. The resultant liquid yielded insoluble films on drying. III A similar resin was prepared, without hydrochloric acid, on the surface of a steel sheet. IV. The polyacrolein was used in solution in aqueous sodium sulphite containing excess sulphite ions and m-cresol replaced the phenol. V Describes the preparation of a foam.
