Abstract: 757,602. Moulding-machines. BUHRER, E. Sept. 22, 1953 [Oct. 22, 1955], No. 26111/53. Class 83 (1). In foundry moulding, the granular material is subjected to a preliminary and a final compression, and a surplus of material is initially poured over the pattern and removed between the preliminary and final compression operations, the surplus material being supported by means which increase the height of the moulding-box. A moulding-machine comprises a ramming piston 2 and a jolt piston 3, a pattern-plate and pattern 4, 5, being supported on a jolt table 3a. A frame 7 is supported by taperpins 37 on a head 36 which is rotatable about, and vertically movable by means of, a piston-rod 38, so that the frame may be swung into a position resting on a moulding-box 6, the piston-rod 38 being lowered so that the pins 37 disengage from the frame 7. The edges of the frame form a pyramid-shaped extension to the moulding-box, and sand is fed thereto from a silo 43 through a sieve 42 vibrated by an electromagnet 44, a predetermined amount being sieved by a time switch in the control circuit. The flask is then jolted and surplus sand removed by a knife 8 which is moved across the frame 7 by endless-chains driven through a piston-operated rack, pins on the chain-sprockets 13 opening a flap 9 to allow the surplus sand to be swept therethrough by the knife. The jolting-blow is resiliently damped by bar-type impact members 46 in the press piston 2, made of highly elastic material such as synthetic resins re- . inforced with fabric or paper, so that the uniformity of the packing is improved. The frame 7 is then engaged by the pins 37 and lifted off the frame 6, leaving the precompressed sand projecting above the top of the moulding- box. A squeeze board 30 is then rotated into position over the moulding-box, which is pressed against it to compress the sand as far as the top edge of the moulding box.

Title: A process for preparing hypochlorite-treated light hydrocarbon oils having a reducedcorrosivity towards iron
IPC: C10G75/00
Filed: 1954-09-09
Abstract: Hydrocarbon oil having an end boiling point not exceeding 350 DEG C. is treated, to reduce its corrosivity towards iron, with hypochlorite and subsequently with alkali metal mercaptides having at least 2 carbon atoms, so that the acid number of the treated oil is reduced to 0.01 or less and the oil gives a negative doctor test.  The mercaptides may be formed in situ in the oil by addition thereto of the mercaptans and the alkali metal hydroxide solution; aliphatic and aromatic mercaptans are referred to and tertiary C6 mercaptans and thiophenol are specified. Alternatively, the mercaptides may be formed by the interaction of an akali metal hydroxide and a mercaptan-containing hydrocarbon oil free from components boiling below 25 DEG C., which may be of the same origin as the hypochlorite-treated oil; an aqueous or alcoholic solution of the alkali may be used, e.g. a 10-30 per cent by weight solution of sodium or potassium hydroxide.  The oil and alkali solution may be stirred with a turbomixer.  The hypochlorite treatment may be effected with an aqueous alkaline solution of sodium or calcium hypochlorite, e.g. with a solution containing 0.1-5 per cent by weight of sodium hypochlorite, 1-30 per cent of sodium hydroxide and 1 - 25 per cent sodium chloride. After treatment of the oil with the mercaptides, it may be further treated with an aqueous alkali metal hydroxide solution and/or water and/or an absorbent.  Gasolines, kerosenes and straightrun, cracked or reformed hydrocarbon oils may be treated. Corrosion inhibitors, such as substituted or unsubstituted aliphatic or cycloaliphatic monocarboxylic acids having at least 12 carbon atoms, e.g. oleic acid, and dicarboxylic acids having at least 8 carbon atoms; antioxidants, e.g., alkyl phenols and aromatic amines; gum inhibitors; anti-knock agents, e.g. tetra-alkyl lead, iron carbonyl and dicyclopentadienyl iron; scavengers, e.g., ethylene dichloride and dibromide and tricresyl phosphate; and dyes, may be added to the treated oil.
