Patent GB-721235-A (GB)
Title: Improvements in or relating to method of irradiating matter with electrons
Inventor: ROBINSON DENIS MORRELL
IPC: A23L3/26
Filed: 1952-06-12
Abstract: <PICT:0721235/III/1> <PICT:0721235/III/2> <PICT:0721235/III/3> Apparatus for ionizing matter comprises means for creating an electron beam with at least 500,000 volts energy, means for supporting the matter in the path of the beam, and means for causing the beam to have scanning or oscillatory movement with relation to the supported matter.  In the arrangement shown in Fig. 2, the material 5 to be irradiated is placed on a conveyer belt 4 which moves in the direction of the arrow so that the material is carried under the window 3 of an acceleration tube. Electrons of several million volts energy pass through the window, which may be of aluminium, and are deflected to and fro across the material by means of deflection plates 12, 13.  The scanning frequency may be 60 to 1,000 cycles per second or higher and the scanning angle may be 50 to 90 degrees.  Since the irradiation intensity is proportional to the cosine of the angle of incidence, the thickness of the material or the scanning speed may be varied to compensate for this effect at large scanning angles; alternatively, the scanning angle may be restricted to 8 degrees so that no compensation is necessary.  The beam may have a diameter of 1 inch or 1/4 inch or less, and may be suppressed for one direction of the scan; the beam may be deflected in two directions, which may be at right angles, by a suitable arrangement of deflecting coils and/or deflecting plates. The cathode may be displaced mechanically to adjust the centre line of the beam, or the cathode may be oscillated mechanically with respect to the acceleration tube to produce the scanning.  As an alternative, the acceleration tube as a whole may be oscillated mechanically with respect to the matter to be treated.  In the arrangement shown in Fig. 2, the beam is deflected after it emerges from the tube; in the modification shown in Fig. 3, the tube is flared at the end and the beam is deflected inside the tube by deflecting plates or by coils which may be inside the tube.  The electron permeable window may be cooled by a spray of liquid or gas.  In one arrangement, Fig. 4, the tube is provided with two windows 28, 29 and the space between them is filled with helium at atmospheric pressure, the helium being circulated by a pump 31 and discharged through a jet against the window 28.

Title: Process for the manufacture of thin shaped structures, such as filaments or foils, from linear polyesters
IPC: B29D7/00
Filed: 1956-05-14
Abstract: An unstretched shaped structure made from a linear polyester, e.g. a filament, thread or film, is rendered plastic at a temperature between the second order transition temperature and the apparent minimum crystallization temperature of the polyester by means of steam or water as the plasticizing medium, then subjected, while in the plastic state, in at least one direction to permanent plastic deformation without molecular orientation, reconverted into the non-plastic state by reducing the temperature or removing the structure from the plasticizing medium, and stretched in this non-plastic state with molecular orientation. The preferred temperature range for plastic deformation without orientation is 70-100 DEG  C.  The plastic deformation of the shaped structure may take the form of elongation, if desired in a direction deviating from the longitudinal, e.g. at right-angles thereto, and it may be assisted by mechanical means, e.g. by passage of the shaped structure between smooth, fluted or grooved rollers immersed in the plasticising medium.  The shaped structure, while in the plastic state, may be subjected simultaneously or in either order to elongation without orientation in the longitudinal direction and to deformation without orientation in a different direction.  If water is the plasticizing medium a wetting-agent may be added; if steam is the plasticizing medium the shaped structure may be previously treated with a wetting-agent.  If desired, the path of the shaped structure through the plasticizing medium may be varied by use of an oscillating link-pin.  The process may be applied to shaped structures several months old as well as to freshly-made structures. The final stretching with molecular orientation may be carried out with or without the application of heat. Specified polyesters are polymethylene terephthalates, particularly polyethylene terephthalate as such or modified by the replacement of a small proportion of glycol (used in its manufacture) by 1:4-butane diol or hexamethylene glycol or by the replacement of a part of the terephthalic acid by another dicarboxylic acid, e.g. adipic, sebacic, naphthalene-2:7-dicarboxylic, or isophthalic acid.  Polyesters derived from hydroxy-carboxylic acids, e.g. para-o -hydroxybutoxybenzoic acid or hydroxypivalic acid, may also be treated.  Examples are given.  Specifications 695,567 and 831,961 are referred to.
