Title: Process for preparing thermoplastic tapes of varied cross-sections
Inventor: LEFEVRE LLOYD EDWARD
IPC: C08J9/26
Filed: 1958-01-21
Abstract: <PICT:0833126/IV (a)/1> Thermoplastic tapes of various cross-sections are made by a process comprising, as essential steps in sequence, the localized coagulation of a latex of a normally crystalline vinylidene chloride copolymer to form a flat, continuous, coherent coagulum having a porosity gradient from one surface to the other, washing the coagulum free of coagulant, cutting the coagulum, if necessary, to form a tape, drying the tape below its fusion temperature and finally exposing only the more porous surface of the tape to radiant heat at a temperature between the fusion temperature and the decomposition temperature of the copolymer to fuse the coagulum and simultaneously to roll the edges of the tape without causing fusion of the layers. The tape may be from 1/16 to 1/2 inch wide, and may be made by depositing on a non-porous base wetted with a coagulant solution a latex of a copolymer comprising 92-99% by weight of vinylidene chloride and 8-1% by weight of acrylonitrile.  The more porous side (the underside) only of the tape may be exposed to radiant heat at from 175-300 DEG  C., preferably for not more than a few seconds.  As shown, a tape 10 obtained as described above, passes through snubbing feed-rolls 11, the more porous surface being uppermost, thence around the idler roll 12 and preheat drum 13, to a supercooling roll 14, and is finally taken up by snubbing take-up rolls 15, tape tension being adjusted by the relative speeds of rolls 11 and 15.  A radiant preheater 16 may also be fitted above drum 13.  Shortly after leaving the drum, the tape is heated by a second radiant heater 17 and this causes fusion and shaping of the tape to the form of Figs. 2-6, the cross-section progressing from that of Fig. 2 to that of Fig. 6 as the tape temperature is raised.

Title: Improvements in or relating to the reaction of organic mercaptans with formaldehyde and ammonia
IPC: C07D277/80
Filed: 1948-01-27
Abstract: A product containing more than one molecular proportion of formaldehyde and less than one molecular proportion of ammonia combined with each molecular proportion of mercaptothiazole is prepared by heating 3 mols. of a mercaptothiazole with at least 5 mols. of formaldehyde and about 1 mol. of ammonia in aqueous medium. The product probably has the formula: (RS)3C6H10O2N, where R is a thiazyl radical, e.g. 4-methyl or 4-ethyl thiazyl, or dihydrothiazyl, and is preferably arylene thiazyl, e.g. naphthothiazyl, or 6-nitro-, 5-chloro-, 4-methyl- or 4-phenyl benzothiazyl.  In the above cases the 2-mercapto derivative is used in the reaction.  In an example, mercaptobenzothiazole (1.2 mols.) and 37 per cent formaldehyde (2 mols.) in suspension in aqueous sodium carbonate (just alkaline) are heated with ammonium hydroxide (0.46 mols.) at about 90 DEG  C. to give a product C27H22O2N4S6.  The Specification as open to inspection under Sect. 91 states that the group R may be any organic group, and specifies butyl, amyl, lauryl, phenyl and b -naphthyl.  This subject-matter does not appear in the Specification as accepted.ALSO:The product obtained by heating 3 mols. of a mercaptothiazole with at least five mols. of formaldehyde and about 1 mol. of aqueous ammonia (see Group IV (b)), and which contains more than one molecular proportion of formaldehyde and less than one molecular proportion of ammonia combined with each molecular proportion of the thiazole, is used to accelerate the vulcanization of rubber and to treat tyre cord to improve the adhesion.

Title: Plant for making sand moulds
IPC: B22C11/08
Filed: 1933-01-26
Abstract: 408,770. Moulding-plant. BAILLOT, A., Rue Alphonse Helbronner, St.-Ouen, Seine, France. Jan. 26, 1933, No. 2500. Convention date, Oct. 28, 1932. [Class 83 (i).] Moulding-machines.-A machine for making sand moulds has a plurality of platforms 1, such as described in Specification 399,683, [Group XXX], capable of vertical movement on an intermittently-moving endless conveyer C which carries flasks 14, placed on the platforms, to devices for filling and ramming, the conveyer being locked against movement during both these operations, stripping means also being provided. Each platform carries a pattern plate 12, Fig. 2, and a spring- supported false flask 13 upon which an empty flask 14 is placed by hand. When pairs of flasks reach the filling and ramming positions, a stop 4 on a platform 1 engages a lever 58 on a fixed pivot and thus lifts a rod 56 to open a switch 5 in the circuit of the motor 3, Fig. 1, and switch-on a brake 6 thus stopping the conveyer. Hoppers 27 are each charged with a predetermined quantity of sand from a hopper 20, having an adjustable opening A, by a belt 21 which is driven by a motor 24 stopped automatically by a switch 26. The hoppers 27 are discharged into the two flasks 14 beneath them by closures 28 and handles 30, and the motor 24 restarted by a hand-switch 23. A handle 43, Fig. 1, is also pressed down to insert positioning bolts 42 between adjacent platforms and open a cock to admit fluid pressure below plungers 34, Fig. 2, and raise these platforms, from the conveyer to press the moulds against adjustable or self-adjusting heads 38. The handle 43 is then returned to lower the plungers, the springs 18 drawing the mould from the patterns. Inclines 51, Fig. 6, connected to the pistons 34 engage bell cranks 54 which prevent the rod 56 from being lowered to start the motor 3 until the moulds &c. have been lowered. The motor 3 is restarted by pressing the switch 2, Fig. 2, until the levers 58 are clear of the stops 4. In a modification of stops 4 act directly on one switch and the rams 34 on two other switches all in the circuit of the motor 3. The moulds are then removed by hand. If desired the belts 21 may deliver sand directly to the flasks while at rest or a single press button may be used to start both the motors 3 and 24. According to modifications the false flasks may be arranged above instead of below-the flasks and may be filled from ordinary hoppers, the closures 28 being operated automatically or by hand, and, instead of being dealt with in " pairs," the moulds may be dealt with singly or in numbers larger than two.
