Title: Process for preparing Linear Polyesters
IPC: C08G63/84
Filed: 1967-08-16
Abstract: 1,163,157. Catalysts for making linear polyesters. FARBWERKE HOECHST A.G. 16 Aug., 1967 [16 Aug., 1966], No. 37722/67. Heading C3R. In the manufacture of linear polyesters by polycondensing a bis-diol ester of an aromatic dicarboxylic acid, there is used as catalyst a mixed anhydride of (a) orthoboric acid, a condensed boric acid, a monoalkyl-, dialkyl., monoaryl-, diaryl-, monoalkoxy-, dialkoxy-, monoaryloxy- or diaryloxyboric acid, tetrahydroxoboric acid or a salt of any of the above acids and (b) an aliphatic or aromatic mono- or di-carboxylic acid containing not more than 18 carbon atoms. As salts of the acids (a) there may be used the alkali metal, alkaline earth metal, magnesium, beryllium, cadmium, nickel, zinc, manganese, cobalt, ammonium or pyridinium salts. The acids (b) may be chlorinated or fluorinated and may contain phenolic hydroxyl groups that condense with the boric acid. The catalysts may be in the form of an adduct with a compound containing a donor oxygen, sulphur or nitrogen atom (e.g. dimethylamine). When the diol esters are prepared by an ester-interchange reaction, there may be used as esterinterchange catalyst Zn, Co or Mn acetates or disalicylato-borates. Specified diol esters are those of terephthalic, isophthalic, 2: 6-naphthalenedicarboxylic, diphenyl-4: 4<SP>1</SP>-dicarboxylic or 4: 4<SP>1</SP>-sulphonyldibenzoic acids and ethylene glycol, trimethylene glycol, tetramethylene glycol, neopentylene glycol, 1: 2-dimethylolcyclobutane and 1: 4-dimethylolcyclohexane as well as mixtures of such esters and diol esters of adipic, pimelic, sebacic, hexahydroterephthalic and cyclobutane - 1: 2 - dicarboxylic acid. Examples describe the polycondensation of bisdiol esters derived from (1)-(3), (6) and (8)- (10) dimethyl terephthalate and ethylene glycol; (5) dimethyl terephthalate, dimethyl sebacate and ethylene glycol; (7) the dimethyl ester of 2: 6-naphthalenedicarboxylic acid and ethylene glycol. Example (8) describes the polycondensation of a mixture of the diol ester from dimethyl terephthalate and ethylene glycol and the diol ester from the dimethyl ester of 1: 2-cyclebutanedicarboxylic acid and ethylene glycol.

Abstract: 951,574. Refrigerating. MALAKER LABORATORIES Inc. Oct. 5, 1962, No. 37800/62. Heading F4H. A refrigerating engine operating on a modified Stirling cycle comprises parallel compression and expansion cylinders 13 and 17 projecting at right angles from a housing 7, the compression and expansion pistons 14 and 18 being reciprocated in their respective cylinders with a phase difference of 90 degrees by suitable cranks 9 and 10 and connecting rods 11 and 12. After the compression stroke gas is passed through a perforated plate 15 which conducts the heat of compression to the cylinder walls to be dissipated by fins 25, then through a regenerator 16, a tube 19, a passage 20 and a perforated plate 21 to the expansion cylinder. The passage 20 is formed in a plug 22 of highly heat conducting material to which is attached a flexible metal conductor 24, the latter being led to the apparatus to be cooled. After expansion in the cylinder 17 the gas is returned to the cylinder 13 via the regenerator 16. The ends of the cylinders are surrounded by insulation 26. The cranks 9 and 10 are rotated by a crank shaft 3 which is driven, through a reduction gear-box 2, by an electric motor 1.

Abstract: 1395959 Casting objects of circular crosssection MITSUBISHI JUKOGYO KK 18 Aug 1972 [25 Aug 1971] 38751/72 Heading B3F An article of circular cross-section is made by continuously melting metal in a mould 5, withdrawing solidified metal from the mould and leading it around a circular path. The molten metal is formed by electroslag remelting of consumable electrodes 13, slag being continuously fed into the mould from a hopper 27. The bottom of the mould is initially closed by a starter bar 12 which is movable along a circular path by means of an arm 11 attached to a rotating shaft 7. When the starter bar 12 reaches the position shown in chain lines in Fig. 6, it is cut off from the casting 2 and the latter drawn along the circular path by arms 33 until the head of the casting approaches the top of the mould, Fig. 7 (not shown). Auxiliary mould pieces (34) and (37) are then attached to the top of the mould and melting of the electrodes continued until the two ends of the casting have been joined together. When a mould having a curved horizontal cross-section is used, the process may be used to form a barrel-shaped member 2, Fig. 1 (not shown). Two dish-shaped members 1 may be cut from the member 2 and used as end pieces in the mould 5 during the formation of a further barrel-shaped member 2, Fig. 8. As the further member 2 is formed it becomes welded to the dish-shaped members 1 to form a sphere. The dish-shaped members 1 may each be provided with a hole 38 through which the shaft 7 passes and through which pieces of the mould may be removed on completion of the process.

When starting from cold, a rod 20 is in the position shown in Fig. 1 until the engine is turned. This causes pneumatic element 22 to move rod 20 leftwards a distance d so that throttle element 7 opens slightly. Temperature sensitive element 38 is heated by resistor 40, e.g. a positive temperature coefficient thermistor, which is energized by closure of switch 43 when the engine is started and after a few seconds or a few tens of seconds, depending upon the ambient temperature, a rod 37 is moved leftward from the element 38 by expansion of a substance therein to move abutment 31 to the left, allowing the pneumatic element 22 to open the throttle element 7 until the rod 20 abuts a screw 29.
