Title: Basic azo dyes
Inventor: LEUCHS DIETER
IPC: C09B44/20
Filed: 1964-01-02
Abstract: The invention comprises a basic dye having a cation of the formula <FORM:1018458/C4-C5/1> in which K denotes the radical of an amino compound capable of coupling or an enamine capable of coupling, X denotes an alkyl radical, an aryl radical, a hydroxyl group, an alkoxy group, an alkylamino radical or an arylamino radical, R1 denotes an alphatic radical and R2 denotes an alkyl radical or an aryl radical and a process for the preparation thereof wherein an azo dye of the general formula <FORM:1018458/C4-C5/2> is alkylated.

Title: Improvements in or relating to a process and apparatus for testing the correct resilience of ring travellers for spinning machines and the like
IPC: D01H7/60
Filed: 1927-01-04
Abstract: 268,731. Hofmann, C. April 3, 1926, [Convention date]. Testing physical qualities of materials.-Comprising a process for testing the ring travellers for spinning machines in which the traveller is first gauged for dimensions and width of gap, is then bent up within the range for forcing it on to the race ring, and then further bent up, the breakage point or point at which permanent set access being indicated or recorded. The traveller 1 shaped as in Fig. 1 is placed with its gap over two small lugs on two jaws 4, 5 pivoted on a fulcrum 6. The short jaw 4 is fixed to the base board 7 while the longer jaw is extended to form a lever 5 having an handle 8 and carrying a recording pencil which projects through a slot 14 to engage a paper sheet carried by a slide 12. A slot 16 is also provided to accommodate two adjustable stops 10, 11. The lever 5 is brought against the stop 10 and the stop 11 first placed at that point corresponding to an opening of the gap in the traveller sufficient to force it on to the race ring. The lever is then slowly moved up to the stop 11. If the traveller cracks before this point is reached it is too hard. If on moving the lever back to its initial position the traveller does not return to its basic form it is too soft. On releasing the stop 11 and moving the lever to the limit of the slot the traveller should break and if it does not break it is too soft. By reading off on the scale 9 or the second sheet the point at which breakage occurs may be observed. In order that this point may be determined accurately, two further forms are shown in which the jaw 4 is not fixed but held against a stop by an adjustably loaded spring or lever system and weight pan. On breakage in these forms the jaw is automatically returned to initial position.

Title: Improvements in or relating to the manufacture of eyelets
IPC: B29C45/14
Filed: 1950-01-12
Abstract: 668,110. Making eyelets. BRITISH UNITED SHOE MACHINERY CO., Ltd. Jan. 12, 1950. [Jan. 13, 1949] No. 794/50. Class 87(ii). An eyelet of the type comprising a hollow metal barrel having an integral outturned flange at one end, the flange being enveloped in plastic material, is made by confining the flange within a space in a mould and then injecting plastic material into the mould. The apparatus shown is for making 100 eyelets at a time, the eyelets as they come from the mould being joined by waste material from which they are later separated. The apparatus comprises two mould parts 9, 10, Fig. 3, separable vertically by raising the part 10. The lower part 9 comprises a block 128 in the upper face of which slidingly fits a plate 134. Through this plate extend one hundred vertical bores 142, in ten rows of ten. Each bore supports an eyelet barrel 56, Figs. 3 and 6, which is clamped therein by a tool 50 fixed in the upper mould part 10. The mould cavities and runners 62, 64 are formed in the underside of part 10. Fig. 1 shows the underside of mould part 10 (only twenty mould cavities being shown). The material is injected at 100, Figs. 1 and 3, and travels along the central sprue channel 98 and thence by way of runners 62 into the mould cavities. The pair of runners 62A that are most remote from the injection point 100 have entrances that extend at right-angles to sprue channel 98, but the four central pairs of runners have oblique entrances 108 as shown, the result being that the remote mould cavities get filled first. Each junction C may be curved in contour instead of pointed as shown. The runners 62B near the nozzle are filled by material which has first passed through the twenty mould cavities shown. After injection the part 10 is raised, whereupon ejector pins 34, the lower ends of which have been held flush with the upper faces of runners 62, tend to dislodge the 100-eyelet moulded assembly 160 (part of which is shown in Fig. 7) from part 10. These pins are secured to a plate 20, and the weight of the plate and pins normally dislodges the assembly: if it does not, ears 22, 24 on plate 20 strike stops 70, 72 and the assembly is forced off part 10. Serpentine heating pipes 82, 150 are embedded in parts 9, 10. The parts 9, 10 are registered by dowels 122 fixed to part 10 and entering bores 130 in part 9. The material used may be cellulose acetate The material may enter the mould at 340 ‹F., and the temperature of the mould may be kept at 140 ‹F. Specification 8896/05, [Class 87], is referred to.
