Patent GB-890005-A (GB)
Title: Improvements in or relating to the stretching of organic polymer film
IPC: B29C55/06
Filed: 1960-06-14
Abstract: Continuous film of organic thermoplastic polymeric material, particularly polyethylene terephthalate, is longitudinally stretched (as by being passed between two spaced pairs of nip rolls, of which the second pair rotate at a higher peripheral speed than the first) while the film is at a temperature Ts at which molecular orientation occurs, and the film moving between the pairs of feed and draw rolls is uniformly cooled to a temperature Tq beginning abruptly at a predetermined point between the pairs of rolls, Tq being a temperature at which the applied stress is not sufficient to deform permanently the already stretched film past its elastic limit.  In the case of polyethylene terephthalate films Ts may be within the range 80 DEG -155 DEG C., preferably 80 DEG -100 DEG C.  In the latter case Tq may be below the second order transition temperature of the polymer. The film is preferably cooled to the temperature Tq at a point nearer to the feed rolls than to the draw rolls, e.g. by means of a narrow blast of cold air impinging on the film across its width.  Alternatively the film may be cooled to the temperature Tq by contact with one or more rollers which are cooled by means of a cooling fluid.  The film may be heated to temperature Ts by means of feed rolls heated to this temperature.  The draw rolls may be maintained either at room temperature or at an elevated temperature (e.g. 100 DEG -225 DEG C. in the case of polyethylene terephthalate film), if simultaneous stretching and heat setting of the film is desired.  The process prevents too great a reduction in film width and may be applied to the stretching of narrow films.  Specification 890,004 is referred to.

Filed: 1932-07-25
Abstract: 388,659. Gumming envelopes. PFLANZE, C. F., 823, Big Bend Road, Webster Groves, Missouri, U.S.A. July 25, 1932, No. 20954. [Class 94 (ii).] A mechanism for gumming envelopes in envelope-making machines includes means for presenting envelope blanks one at a time to a rotary gummer arranged to contact the blank at an edge portion thereof to apply gum thereto during its rotary movement, the gummer being arranged to overlap the edge portion of the envelope blank to ensure application of gum to the precise edge. The blanks E, supported on wires B, are fed forward by hooks F on endless bands C. The rotary gummer 27<1>, shaped to accord with the envelope flap, is fed with gum from a bath 28, by rotating members 32, 36, 34. The gummer 27<1>, which overlaps the edge of the envelope flap, presses on to a belt 20, supported over pulleys 5, 19, which is intermittently moved by the shaft 6 through a Geneva motion G. The gum thus taken on the belt 20 due to the overlap is removed by the belt traversing a cleansing fluid 21 and a rotary scrubbing device 23. The damped belt is stated to counteract any tendency of the flap edges to warp when gum is applied to the upper surface.

Title: Manufacture of racemic compounds of the 1-hydroxyphenyl-2-aminopropanol (1) series
Filed: 1932-07-25
Abstract: Racemic 1-hydroxyphenyl-2-aminopropanols (1) are prepared by reducing a l-1-hydroxyphenyl-2-ketopropanol-(1) with hydrogen at a raised temperature in the presence of ammonia or a primary or secondary amine and or a precious metal or a metal of the nickel group (iron, cobalt, nickel or copper).  When using an alkylamine or arylamine, the product is alkylated or arylated in the amino group, but in the case of ammonia or an aralkylamine there is obtained a product unsubstituted in the amino group, except when an aralkylamine is used in conjunction with a catalyst of the nickel group.  In the latter case, the aralkylamino compound is formed and requires to be further hydrogenated in the presence of a precious metal in order to split off the aralkyl group.  The reaction is preferably effected in an alcoholic solution. Examples are given of the preparation of (1) racemic m-hydroxyphenylpropanolamine by hydrogenating l-m-hydroxyphenylacetylcarbinol in the presence of benzylamine and palladium; using nickel as the catalyst, the racemic m-hydroxyphenylbenzylaminopropanol is obtained, from which the benzyl group is split off by continuing the hydrogenation in presence of palladium; (2) racemic m-hydroxyphenylaminopropanol from l-m-hydroxyphenylacetylcarbinol using ammonia and palladium; (3) racemic p-hydroxyphenylaminopropanol by hydrogenation of l-p-hydroxyphenylacetylcarbinol in the presence of benzylamine and nickel, and hydrogenating the product in presence of palladium to split off the benzyl group; (4) racemic 3 : 4-dihydroxyphenylaminopropanol from l-3 : 4 - dihydroxyphenylacetylcarbinol using benzylamine and palladium; (5) racemic 1-m-hydroxyphenyl-2-methylaminopropanol-(1) by hydrogenation of l-m-hydroxyphenylacetylcarbinol in presence of methylamine and platinum.  Laevo - 3 : 4 - dihydroxyphenylacetylcarbinol is prepared by adding protocatechuic aldehyde to the fermentation product of glucose and beer yeast and extracting with ethyl acetate.

[Also in Division G4] In a rolling mill, the length of a workpiece which has passed through the rolls is measured by a pulse emitter 19 and counter 21, and the distance between the rolls is varied in accordance with this measurement so as to shape the workpiece. Potentiometer 15 provides a bias voltage corresponding to the minimum desired thickness of the workpiece and potentiometer 14 provides a voltage corresponding to the actual distance between the rolls for comparison with the output of a digital to analogue converter 22. Comparator 17 controls the distance between the rolls, e.g. by an hydraulic actuator. Potentiometer 23 provides a variable reference for converter 22 so that the rate of change of thickness with axial position of the workpiece may be varied. A limit switch 20 is provided to interrupt the counting of pulses so as to produce portions of uniform thickness on the workpiece.
