Abstract: 1300324 Phenol - urea - formaldehyde resins; foundry mould compositions DEUTSCHE TEXACO AG 16 April 1970 [30 April 1969 17 March 1970] 18284/70 Headings C3N and C3R A thermosetting adhesive suitable for binding foundry cores is produced by co-condensing a phenol, urea, acetone, formaldehyde and a C 2-4  dihydric alcohol. The phenol may be phenol itself, the alcohol ethylene glycol and the formaldehyde formalin. In one preparation process (Example 1), a phenol/formaldehyde resole is first prepared in the presence of sodium hydroxide. This is then treated with urea, acetone, further formaldehyde and sodium phosphate as pH adjuster. Towards the end of this reaction, the pH is made acid by addition of formic acid and, after completion of the reaction at acid pH, the ethylene glycol is added. When the ethylene glycol reaction is complete, the final resin product is neutralized with sodium hydroxide. In another process (Example 2), a phenol-formaldehyde and a urea-acetoneformaldehyde condensate are prepared separately in the presence of sodium hydroxide and sodium phosphate respectively. The two condensates are then mixed with ethylene glycol and formic acid to provide an acid pH and co-condensed. The product is again neutralized. This resin is mixed with quartz sand, ammonium chloride and iron oxide and moulded into foundry cores cured by the hot box method.

Title: Halogenated organic acids and esters and their manufacture
IPC: C07C55/32
Filed: 1936-07-01
Abstract: Halogenated dicarboxylic acids and their esters are produced by halogenating a compound of the type <FORM:0477840/IV/1> where R1 and R2 may be alkyl, cycloalkyl, aryl or hydrogen, at a temperature not substantially above 0 DEG  C. and separating the high-boiling from the low-boiling halogenated fraction.  Methyl methacrylic ester yields a high-boiling product which is thought to be <FORM:0477840/IV/2> or a compound containing one or two additional chlorine atoms in the ester methyl groups, which are removed on hydrolysis. Suitable halogenation catalysts may be used such as bromine, sulphur, iodine, ferric chloride or stannic chloride.  The products may be converted into other compounds by reaction with alkali metal salts of acids, or metal alcoholates.  The products of the invention may be used as plasticizers for cellulose esters and ethers or for the preparation of synthetic resins.  The low-boiling fractions may be used as solvents, insecticides and lachrymators. Examples describe (1) and (2) the chlorination of methyl methacrylate at 0 DEG  C. in the presence of bromine and carbon tetrachloride; a trichlor derivative is first formed, which may be converted into a diethoxy dicarboxylic acid by reaction with sodium ethylate or hydrolyzed to a dichlordicarboxylic acid by sodium hydroxide; (3) and (4) the chlorination of propyl methacrylate at -10 DEG  C. and the hydrolysis of the product to the corresponding acid; (5) and (6) the chlorination of cyclohexyl methacrylate at -10 DEG  C. and of methyl acrylate at 0 DEG  C.  The reaction may be carried out in the presence of a polymerization inhibitor such as hydroquinone. Specification 436,161 is referred to.

Filed: 1956-06-14
Abstract: 815,612. Treating charge. TAYLOR, A. D. F. June 14, 1956, No. 18414/56. Class 7(2) Apparatus for supplying liquid to the induction pipe comprises a container 1 for the liquid adapted to be sealed against atmosphere, a connection 15, 17a, 17 between the container and the induction pipe, and means to divert suction from the induction pipe from the air space to the liquid to enable the liquid to be drawn off from the container. Thus at low power running little or no suction is set up in the jet tube 15. At higher power and greater speed the suction causes the cap 4 to be drawn down and close the passage 6. The suction then acts in the tube 5a and liquid is drawn into the induction pipe. A passage 9 also leads to the induction pipe and this passage enables the liquid to be drawn off. An adjustable valve 27 (Fig. 5) may be associated with the jet tube 15. The Specification refers to known types of apparatus for introducing water into the induction manifold.

The valve lever d is actuated by a sliding flanged sleeve having a screw-threaded connection with a rotatable but non-slidable sleeve e driven by the meter. The sleeve b has another flange b<1> which engages the short arm l of the locking lever, thereby moving the long arm m proportionally to the amount of gas prepaid. At the end of the travel of the sleeve b in the valve-opening direction, the flange b<1> engages an abrupt rise l<1> on the arm l and moves the end of the long arm m into engagement with the teeth of the crown wheel. The arm m works in a slot n, Fig. 3, in the back plate of the coin mechanism casing where it engages and operates an indicator slide p. The slide p which is slotted and guided by studs r, carries a pointer s visible through a vertical slot u. When the prepaid gas is consumed, the lever is returned by a weight w, or by a spring.

Abstract: 440,093. Automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. June 28, 1935, No. 18585. Convention date, June 29, 1934. [Class 38 (v)] A thermally - released overload circuitbreaker which may also be moved " on " and "off" by a dolly 31 comprises a contactcarrying arm 22 pivoted at 23 and urged to the open position by a spring 28, and a toggle 32, 33 connecting the arm 22 to the dolly 31, the toggle normally remaining in the straight, slightly overset position shown, in which it transmits movement from the dolly to the contact arm causing the latter to open and close. A trip member 60, pivoted at 40, is pulled upwards by a spring 75 and has two arms the upper of which is adapted to engage the knee of the toggle and break it and the lower 63 of which passes through an insulating base and through a slot in a floating member 65 which carries two pivoted arms 66, 67 pressed outwards by a leaf spring 80 and engaging wheels 56, 57 on two shafts soldered to bushings, not shown. Adjacent each shaft is a heating coil, these being arranged in two of the phases of the three-phase switch. Upon overload in either or both phases, the solder melts allowing the shaft or shafts to rotate and the members 65, 66 to move upward. The upper arm of the trip member 60 thereupon causes the toggle to collapse and the switch to open. A spring 38 tends always to straighten the toggle and it now does this by forcing the dolly into the " off " position. Simultaneously a projection 62 on the contact arm 22 engages the arm 63 of the trip lever and moves it back into its original position. The solder than hardens and the thermal release mechanism is thus reset. To reclose the switch the dolly is moved " on."
