Title: Piston pump
IPC: F04B1/04
Filed: 1960-09-13
Abstract: 891,117. Radial-cylinder pumps. MUNCHNER MOTORZUBEHOR G.m.b.H. Sept. 13, 1960 [Sept. 17, 1959], No. 31536/60. Class 102(1). In a cam-and-lever actuated, radial-cylinder pump the stroke of the piston is varied by moving the fulcrum of an actuating lever 17 relative to the base of the piston. Lever 17 is pivoted on a pintle 14a carried by a rotatable bearing ring 16 and a control disc 14, manually rotatable relative to a pump housing 1 by a handle 14b. Reciprocatory motion of lever 17 is transmitted to a spring loaded piston 8 through a roller 13 which seats in a groove 17b running the length of lever 17. A roller 17a on lever 17 engages a cam surface 4 on a cam shaft 2. A number of pump units, e.g. three, are positioned radially of shaft 2. Liquid enters the pump units from a suction conduit via a liquid-filled chamber 1a, ducts 5a and valves 6a and is delivered via valves 6b, ducts 5b and headers 1b to a delivery conduit. Valves 6a and 6b are spring-loaded. Detents or self-jamming means may be used in conjunction with a scale and pointer for setting control disc 14.

Patent GB-759347-A (GB)
Title: Purification of phenol
Filed: 1954-11-03
Abstract: A process of purifying phenol produced by the acidic decomposition of isopropylbenzene hydroperoxide and containing impurities of similar boiling range to that of phenol comprises contacting said impure phenol in the liquid phase with hexane boiling in the range of about 62 DEG  C. to about 67 DEG  C., allowing the resulting mixture to separate into two phases, separating the phenol phase from the hexane phase and recovering the phenol from the phenol phase.  The contacting of the phenol with hexane may be carried out in a two-phase or in a single-phase system when phenol may be caused to separate by addition of water or by cooling the solution.  The hydroperoxide may be obtained by the oxidation of isopropylbenzene which may be pure or may contain butyl benzenes. Impurities which are stated to be removed by the process include those formed in the cracking of phenol residues which contain 7-hydroxycumene, cumyl phenol and a -hydroxy-p-isopropylcymyl phenol which yield a -methylstyrene and p - isopropenyl - a  - methylstyrene.  Mesityl oxide formed from acetone is also removed.  The process may be carried out batchwise or in a countercurrent extraction column.  In examples crude phenol, prepared by oxidation of isopropylbenzene containing di-isopropyl- and sec.-butyl-benzenes and acidic decomposition of the resulting hydroperoxide, is agitated with hexane and water, and after allowing the mixture to separate into two layers the phenol layer is removed and fractionated (1) and (2); in a similar process a second extraction with hexane is employed; (3); crude phenol is mixed with water and extracted in counter-current with hexane in a Scheibel column.

Title: Process for the manufacture of ethylalcohol-gels
IPC: C10L7/04
Filed: 1927-11-29
Abstract: 281,662. Ohle, H., and Neuscheller, J. Othmar-. Nov. 30, 1926, [Convention date]. Solidified spirit.-Ethyl alcohol is obtained in a solidified form or gel by adding to ethyl alcohol any of the alkali or alkali-earth metal salts of the sulphuric acid half esters of acetone derivatives of sugars and polyvalent alcohols such as diacetone-glucose, diacetone-galactose, a- and #- diacetone-fructose and acetone-glycerine. The potassium salt of a-diacetone-fructose sulphuric acid is particularly suitable and is stated to form a gel with ethyl alcohol when present to the extent of one or two per cent. The gel-forming substance alone or in solution is added to the boiling alcohol and on cooling forms a gel stable at ordinary temperatures, from which the alcohol may be extracted by pressure or heat. The jelly produced is colourless and transparent and the added substances are colourless, tasteless and non toxic so that the jelly is suitable for making beverages, food-stuffs, and medicinal and technical purposes.

Filed: 1963-08-15
Abstract: <PICT:1096913/C1/1> In the manufacture of flat glass in which the glass is in contact with molten metal, e.g. in the float process, an additive for preventing contamination of the metal is added to the molten metal in liquid form.  If the bath is tin the additive may be added as a tin alloy, e.g. of magnesium, zinc or l thium or as an alloy of a metal miore noble than tin, e.g. copper.  In a float glass apparatus tubes 10 are arranged at intervals along each side of the bath, the lower end of the tubes being closed by stainless steel mesh 11. Pellets of alloy are introduced into the tube 10 via an air lock 13 with valves 14, 15 which may be operated automatically.  A carbon plunger 21 pushes the pellet down the tube.  The pellet is melted gradually by the heat of the bath and drips into the bath with which it mixes readily. Any oxide is retained on the mesh 11 or in the tube 10 from which it may be periodically removed.  The apparatus is otherwise conventional.
