Title: Rolling device for tube bending machine
IPC: B21D11/08
Filed: 1958-12-30
Abstract: 874,523. Angular bending. WILMAN, S. Dec. 30, 1958 [Jan. 4, 1958], No. 42060/58. Class 83 (4). A tube bending machine of the type in which the bending is effected by thinning the outside of the bend by a rolling action applied to the inner wall thereof comprises a wheel-carrying head adapted to rotate inside the tube to be bent, said head comprising a rolling wheel and at least one opposed bearing wheel bearing against the inner surface of the tube at a location substantially opposite to the zone engaged by said rolling wheel. A tube 7 to be bent is fed axially over a rotating rolling head 1 carrying a convexly contoured rolling wheel 2, freely rotatable on an eccentric portion 6 of a pin 4, and two cylindrical bearing wheels 3 opposite the wheel 2 and freely rotatable on pins 5. The pin 4 is oscillated during rotation of the head 1 so that the distance between the rolling wheel 2 and a plane containing the axes of the bearing wheels 3 is at a maximum when the wheel 2 is engaging the inner surface of that part of the tube 7 which forms the outer wall of the bend to thin this wall, and is at a minimum when adjacent the inner surface of the inner wall of the bend so as not to thin this part. The head 1 is rotated by a hollow shaft 69 and the rolling wheel 2 is oscillated during such rotation by gearing 9, 10, or through double universal jointmeans, from a shaft 8, 62 extending through the shaft 69. A crank 63 on the shaft 62 and a crank 68 on the shaft 69 are connected by a link 70 and an adjustable link 65, pivoted to the cranks at 72, 64 and to one another by a pivot pin 71 carrying a follower roll 67 running on a cam track 77 to oscillate the crank 63 and thus the shaft 8, relative to the crank 68 and head 1, thus to rock the pin 4. The cam track 77 is of tapered section and, to vary the curvature of the tube bend, may be moved axially by a handoperated screw 75.

Title: Process for improving the dyeability of linear polyesters and linear polyesters having improved dyeing properties
IPC: C08K5/21
Filed: 1965-10-05
Abstract: The dyeability of linear polyesters is improved by incorporating therein from 1-25 weight per cent of a modifier of M.W. 180 to 1000 of the formula I <FORM:1123436/C3/1> <FORM:1123436/C3/2> <FORM:1123436/C3/3> wherein each group R, R1, R2, R3, R4 and R5 may represent a hydrocarbon or heterocyclic radical which may be further substituted, e.g. by further amide, urea or imide groups, and groups R1 and R3 may also be hydrogen, and groups R1 with R2 and R3 with R4 and R with R5 may together form a cyclic group.  The molten modifier may be blended with the molten polyester, or the comminuted polyester may be slurried with a solution of the modifier then dried and melt spun, or polyester fibres may be coated with modifier then heated to cause this to penetrate the fibre surface.  Of 37 specified modifiers for which formul/sA are given the following are typical:- <FORM:1123436/C3/4> <FORM:1123436/C3/5> <FORM:1123436/C3/6> <FORM:1123436/C3/7> <FORM:1123436/C3/8> <FORM:1123436/C3/9> <FORM:1123436/C3/10> <FORM:1123436/C3/11> In examples the modifiers are incorporated into polyethylene terephthalate and this is then dyed with various disperse or premetallized dyes. Suitable disperse dyes include the anthraquinone, azo, disazo, diphenylamine, methine, bispyrazolone and trisazo types.ALSO:The compound <FORM:1123436/C2/1> is prepared by reaction of morpholine with terephthaloyl chloride; the compound <FORM:1123436/C2/2> is prepared by reaction of phenyl isocyanate with N:N1 - diphenyl - ethylene - diamine; the compound <FORM:1123436/C2/3> is prepared by reaction of phthalic anhydride with 1:6-hexamethylene-diamine.ALSO:The dyeability of linear polyesters is improved by incorporating therein from 1-25 wt. % of a modifier of MW 180 to 1000 of the formula I <FORM:1123436/D1-D2/1> wherein each group R,R1,R2,R3,R4,R5, may represent a hydrocarbon or heterocylic radical which may be further substituted e.g. by further amide, urea or imide groups, and groups R1 and R3 may also be hydrogen, and the pairs of groups R and R5, R1 and R2, and R3 and R4 may be joined to form cyclic structures. The incorporation may be achieved by blending the molten modifier with the molten polyester, by slurrying the comminuted polyester with modifier in solution then drying and melt spinning the polyester, or by coating polyester fibres or fabric with the modifier and heating the product to cause the modifier to melt and penetrate the surface.  In Examples modifiers are incorporated in the above ways into polyethylene terephthalate which is then dyed with various disperse or premetallized dyes.  Formulae of 37 suitable modifiers are supplied.

Filed: 1974-10-01
Abstract: 1526202 Fuel injection pumps CAV Ltd 15 Sept 1975 [1 Oct 1974] 42508/74 Heading F1A In a fuel injection pump comprising a reciprocable pumping plunger and a cam 16, 17 for actuating the plunger, the cam 16, 17 is allowed limited movement against the action of a spring 27 due to the reaction force between the plunger and cam, whereby as the reaction force increases the cam moves against the action of the spring 27 and when the reaction force decreases the cam moves under the action of the spring. The movement of the cam results in a delay in the peak pressure which occurs during delivery without any change in the injection period, Fig. 2 (not shown). The cam acts on the spring 27 via a piston 19 and a plunger 26 separated by liquid fed from a source 24 past a non- return valve 23. The piston 19 is loaded by a spring 22 and by adjusting the amount of liquid supplied the position of the piston 19, and thus the timing of injection, is controlled. Spring 27 is in a preloaded state.
