Patent GB-1018953-A (GB)
Title: Method of manufacturing fabrics, especially crepe fabrics
IPC: D02G1/02
Filed: 1962-08-21
Abstract: A method of producing a fabric, more especially a crepe fabric, comprises the steps of, forming a composite yarn by twisting together at least two twisted single yarns, at least one of which is a highly twisted so-called crepe yarn and each of which includes synthetic filaments capable of shrinkage, the filaments of at least one of such single yarns being wholly free from shrinkage, stabilizing the twisted composite yarn by a thermal treatment in a humid atmosphere and at a temperature which is sufficiently low substantially to prevent shrinkage of the filaments, making a fabric with the stablized twisted composite yarn and then submitting the fabric, in a substantially tensionless condition, to a thermal treatment at a temperature sufficiently high to effect complete shrinkage of the synthetic filaments without decomposition of the least heat resistant synthetic filament involved.  As specifically described two multi-filament yarns each twisted to between 2000 and 6500 turns/metre in the same or opposite directions are wound on a bobbin, immersed in water, unless there is a very damp atmosphere, and assembled together with the same tension in each yarn and with a doubling twist of between 1400 and 1800 turns/metre.  The yarn is stabilized in a vacuum chamber with the temperature being slowly increased up to for example 50 DEG C whilst wet steam is introduced. The maximum temperature used is 40% of that which would cause complete shrinkage without degradation.  The yarn is left at this temperature for at least 2 1/2 hours and is then removed at about 40 DEG C.  The yarn which may now be dyed, is woven into a fabric.  The fabric is desized, wound in a very loose state on supports having a very low heat conductivity, and subjected to the shrinkage treatment in a vacuum at 210 DEG C for a few seconds in the presence of steam. The fabric is cooled and removed at a temperature of about 30-40 DEG C.  The high temperature may be reached quickly, or slowly in stages with an eventual rapid final rise. Alternatively the fabric is placed in a high vacuum for about 20 minutes and steam is then admitted to raise the temperature to about 150 DEG C for about 1 minute.  Rapid cooling follows by blowing in nitrogen, and the fabric is removed at a temperature of about 50-60 DEG C.  The two single yarns in the composite yarn may differ in twist, count, degree of contraction and/or material.

Title: Fountain pen
IPC: B43K5/18
Filed: 1939-12-13
Abstract: 537,269. Fountain pens. DEHN, F. B. (Parker Pen Co.) Dec. 13, 1939, No. 32138. [Class 146 (iii)] In a fountain pen, a hollow member having capillary cells to govern the ink feed is open to the ink reservior whereby surplus ink in the feed duct enters the cells to prevent flooding whilst air enters the reservoir when the cells are free of ink. The nib-section is formed by a tubular element 2 closed at the rear end and formed with transverse slits in the upper wall whereby the forward section may be depressed and form a seat for a nib 3. The rear end of the nib is held beneath the unslit part of the wall of the nib-section by a springy element 6 having a protuberance 9 engaging an aperture 4 in the nib 3. The amount of flexure of the nib ran be controlled by a sliding element 29 held in adjusted position by a projection at the rear end engaging notches in the wall of the section. Enclosed in the section is a tubular member 13, the upper wall of which is extended to form the element 6, and is formed with longitudinal channels along which ink is fed from the reservoir 27. Slots 16 cut in the bases of the channels give access to the interior of the member 13 wherein is contained a structure 14 composed of a series of spaced elements which provide a number of capillary cells to absorb any overflow ink. The ink duct 26 tapers towards the nib end, and an air passage 18 arranged diametrically opposite in the member 13 increases in size towards the nib end where it opens to the atmosphere through a vent 24. Ink reaches the nib through slits 17, 8 in the element 6 and section 2 respectively. The vents 16 are smaller in size than the capillary spaces, and these spaces increase in cross-section towards the nib end. A construction employing an ordinary nib is also described. Specification 534,657 is referred to.

In ratchet mechanism in which the ratchet wheel must withstand heavy loadings, as in the hydraulic drive for the revolving grate of a gas producer, the ratchet teeth are of coarse pitch and the driving pawl moves the wheel by one tooth space after a sequence of reciprocations of increasing amplitude while engaging the same tooth. The pawl 7 is held in engagement with the ratchet wheel 9 by gravity or spring means and is carried by a lever 5 pivoted about a fixed spindle 6 and pivotally connected to a hydraulic ram 2. The lever 5 also carries an adjustable stop 13 and a rotatable cam 15 each adapted to contact a lever 10 freely mounted on the spindle 6 and linked to a reversing valve 12. The length of stroke of the ram depends on the distance between the lever 10 and the operating surface of the cam 15. The cam is rotated at each reciprocation to increase this distance by means of the engagement of pegs on the cam with a pawl 17 pivoted to the frame, a spring- loaded retaining pawl 18 being provided. The cam 15 is detachable to allow cams of different contours to be used, thus varying. the speed ratio. Maximum speed may. be obtained by removing the pawl 17 and turning cam 15 to bring the shortest tappet, corresponding to rotation of wheel 9 by one whole tooth space, into operation.
