Patent EP-0089912-A3 (EP)
IPC: D01F6/62
Filed: 1983-02-22
Abstract: A process is described for the production of high 
strength polyester yarn wherein the conventional spin draw 
process has been modified. Yarn having a tenacity of at least 
7.5 g/d and an elongation of at least 9% may be spun using 
this process at a speed of at least 1900 meters per minute. 
The yarn may be used in tire cord and other industrial 
applications.  
     Figures 1 and 2 illustrate in schematic form the general 
process steps of spinning and drawing respectively. Polyes­
ter in the form of melt extrudable polyethylene terephthalate 
(PET) is charged to a hopper 12 which empties into a screw 
extruder 14 which thereupon mixes and heats the polyester 
to a temperature of about 287°C.  
     The now molten polyester is pressure fed by the 
extruder to a spinnarette 16 having a plurality of capillaries 
17 through which the polyester is extruded. The number of 
capillaries can vary from about 50 to over 100. The extruded 
filaments are maintained at a temperature near the melting 
point of PET by a quench delay collar 20 often referred to 
simply as a quench collar. The filaments are then quenched 
by an inert gas or air stream 22 of ambient temperature 
before passing though a chute 24. The filaments 18 are now 
in a solid state.  
     At the end of the chute 24 is a tray and kiss roll 26 which 
applies a conventional spin finish compound to the fila­
ments. The filaments are then converged at point 28 into 
yarn 30, which is thereafter transported by a pretension 
godet 32, godets 34 and guide rolls 36 to winder 38, where 
the yarn is wound and may be either stored for future 
drawing or may be used as feed immediately to the drawing 
process in continuous fashion.  
     The drawing process is illustrated in Figure 2. Yarn 30 
from winder 38 passes between pretention rolls 42 and over 
guide roll 44 to top godet 46. The yarn then travels around 
draw pin 50 which localizes the draw at a point just below top 
godet 46. The amount of draw is governed by the relative 
rotational speeds of top godet 46 and a bottom godet 56, the 
latter rotating at a high speed than top godet 46.  
     After passing over draw pin 50, the yarn 30 passes over a 
platen 52 before being wound on the bottom godet 56. Rolls 
48 and 58 separate the wraps and keep them from rubbing 
against each other. Platen 52 is heated to a temperature of 
about 215°C. to about 230°C. From the bottom godet, the now 
drawn yarn passes through guide loops 60 and is wound 
onto a spool 62. The yarn is now ready for use at this point.

Abstract: An information recording medium (10) according to the 
present invention permits recording with high density, re­
producing, and erasing using electric charges (18). In 
particular, a second insulator film (13) thereof is formed as 
a multi-layer structure with different electric current density 
and charge trapping density for each layer (13a, 13b). With 
this recording medium, satisfactory characteristics for re­
cording, reproducing, and erasing can be obtained using 
films (13) of smaller thickness than for the case of single-­
layer structure, making it possible to extend the life of the 
electrode (15) used for recording and erasing through re­
duction in the voltages required for recording and erasing.

Title: Bandages, components thereof and use
IPC: A61L15/07
Filed: 1984-08-09
Abstract: An orthopaedic bandage is described which comprises a support carrying a vinyl compound which compound polymerises when exposed to a water-activated vinyl polymerisation catalyst. The vinyl compound is a hydrophilic prepolymer which contains more than one polymerisable vinyl group. This prepolymer is in association with at least one component of a water-activatable vinyl polymerisation redox catalyst in solid form in a water pervious coating which is insoluble in the prepolymer. Encapsulation of one component of the catalyst system in a water pervious coating provides a storage stable bandage which is activated by immersion in water and gives a satisfactory working time for immobilising a limb compared to use of an uncoated catalyst.

Abstract: A method of identifying a parameter of a model for a rate 
of loss of boiler efficiency due to a sootblowing operation, in 
a boiler having a plurality of heat traps, comprises measur­
ing a time since a last sootblowing operation in the heat trap 
in question, measuring an overall boiler efficiency at the 
beginning of sootblowing for the heat trap in question, 
measuring a change in efficiency due to the sootblowing 
operation and calculating the parameter using an equation. 
According to the equation, the ratio of efficiency change over 
overall boiler efficiency equals the time factor since the last 
sootblowing operation times the parameter minus a summa­
tion of factors for each of the other heat traps and their 
associated sootblowing operations. The technique is extend­
able to individual sootblowers within a heat trap by using 
fouling rate index rather than overall boiler efficiency.

Title: Method for making a web of interconnected bags

Filed: 1987-09-02
Abstract: The method is used for the production of a web of interconnected bags from a half-tube web consisting of a material which is capable of being adhesively bonded and/or sealed. In the region of the first of the two longitudinal outer edges running in the direction of feeding of the half-tube web, firstly at least one continuous strip is fitted in each case on the top side and on the underside of the half-tube web in pockets which are continuously integrally formed on the web during its feeding, before the separation of the bags, and the two parts of the half-tube web lie loosely one on top of the other in the region of the second longitudinal outer edge which is parallel to the first. Then, the strips are cut to length and their ends are interconnected and the half-tube web is sealed in a cyclical manner transversely, preferably perpendicularly with respect to the feeding direction to form in each case one bag, which is transported transversely, preferably at right angles to the feeding direction and all of these bags are interconnected. In this arrangement, either the pocket of the top side or that of the underside of the half-tube web protrudes beyond the respective other pocket, transversely with respect to the feeding direction, to form the first longitudinal outer edge. Every bag, which is sealed transversely with respect to the feeding direction and is transported in a direction which likewise runs transversely with respect to said feeding direction, is transported by one bag length. Then, the half-tube web is further transported by a bag width and with its first longitudinal outer edge overlaps, in an overlapping region, the second longitudinal outer edge of the bag which is transported transversely with respect to the feeding direction. Finally, the overlapping region is sealed by means of a sealed seam to connect two bags lying one behind the other in the longitudinal direction of the bags.
