Title: Improvements in or relating to knitting methods and machines and products thereof
IPC: D04B1/26
Filed: 1964-07-10
Abstract: A stocking tube, Figs. 7 and 9 (not shown), is knitted by continuous rotary knitting on a circular machine and has constricted portions k, g, which are positioned beneath the welt at the back of the leg and to embrace the portion which is to form the heel so that the adjacent circumferential portions n, p, are of a comparatively looser construction which is enabled to stretch when tension is applied to the fabric as by the wearer flexing the knee whereby the portion n readily stretches to relieve the tension imposed on the fabric, or when the tube is placed on a former for boarding whereby the portion p stretches to enable the tube to conform to the shape of the former. The tube is produced on a two feed machine in which the yarns are separately knitted in alternate courses in the unrestricted portion n, p, and are also knitted separately in alternate courses in alternate wales C, E in the restricted portions, k, p. In the intervening wales B, D the yarns are knitted together as illustrated in Fig. 10 (not shown).  To enable the fabric to be produced the needles knitting the unrestricted area have long butts and those knitting the restricted areas have medium and short butts.  The stitch cam at the main feeder is withdrawable such that the short butt needles are only partially lowered without knitting at that feeder to produce the wales B and D.  To assist the loop formation alternate sinkers in the needle sector having medium and short butts are projected further than usual inwardly to cause the yarn to be drawn over their nebs and ensuring extra lengths of yarns at the main feeder.

Title: Improvements in or relating to seats
IPC: B60N2/04
Filed: 1938-10-04
Abstract: 519,800. Adjustable seats. CHESTON, A.S., BOOTH, J. H., and SLEIGH, H. L. Oct. 4, 1938, Nos. 28734 and 36322. [Class 52 (ii)] 'An adjustable seat, particularly for motor road vehicles or aircraft, wherein the seat proper is carried by pivoted legs mounted on a supporting structure, is provided with a locking lever pivoted to one of the legs, or to each of a pair of legs, for releasable locking engagement with a member on the supporting structure. The seat frame 11, Fig. 1, is connected by pivot pins 14 to four legs 12, 13 and the legs at each side are pivoted on pins 18 within a foot 16 of inverted U-section. A spring 32 tends to move the seat to its forward position, and a pair of locking levers 21 pivoted to the front legs 12 on pins 23 maintain the seat in set position by engaging racks 26 secured within the feet. The locking levers are removed from the racks, for adjustment of the seat, by a handle 33. Slotted plates 27, by engaging pins 28 limit the angular movements of the levers. The upper edges 30 of the slots are serrated so as to constrain the locking levers to move in a step-bystep manner. The pivot pins 14, 18, 23 are supported at both ends so as to take the stress in double shear. In a modification, Fig. 8, the locking levers 21 are pivoted to the rear legs 13 and are operated by a hand-lever 48 rigidly connected to a transverse bar 22 uniting the locking levers. If the feet 16 are arranged to slide within guides 39 catches 43 pivoted on pins 46 in the sliding feet are provided to retain the feet by entering holes 42 in the guides. the hand-lever 48 is, in this modification, pivoted to a bracket carried by the transverse bar 22. An extension 50 of the bracket overhangs the operating lever so that only upward movement of the operating lever influences the locking levers 21. Downward movement of the handlever exerts pressure on a pin 51 and displaces the catches 43 to allow the feet 16 to be slid along their guides. Specification 515,788 is referred to.

Patent GB-785153-A (GB)
Title: Improvements in or relating to separation of acid gases from coal carbonisation gases
IPC: C10K1/12
Filed: 1955-10-11
Abstract: <PICT:0785153/III/1> In recovering acidic gases, for example hydrogen cyanide, hydrogen sulphide and carbon dioxide, from the actifier vapours of a hot-vacuum-actification process for fuel gas purification wherein the gases are passed through condensing equipment, at least one steam jet evacuator is provided in series with the condensing equipment to prevent the formation of hard polymer. Coke-oven gas is treated in a scrubber 4 with a countercurrent of aqueous sodium carbonatebicarbonate solution circulating in a closed circuit between scrubber 4 and actifier 12, the latter being under a vacuum of four inches mercury and being heated by a coil 16.  The recovered acid gases with ammonia, any high-melting compounds and an excess of water vapour pass from actifier 12 to condenser 21 at the same pressure as the actifier.  A petroleum distillate boiling at 100 DEG  to 300 DEG  C. is led from tank 47 by pipe 50 to steam-jacketed vaporizer 52 and thence into the gases through pipe 53 before they enter condenser 21.  The gases are then passed into a jet evacuator 66 into which steam is passed through a line 67.  The exhausted, mixed, steam and gases, leaving the evacuator 66 at about 75 DEG  to 80 DEG  C., are passed through a scrubber 25 counter-current to water from spray 26 to remove ammonia. The gases then flow to condenser 30 after a further injection of oil from pipe 53, and thence through liquid trap 23 to vacuum pump 33. The acid gases at 5-10 lb. pressure pass to final condenser 35, after treatment with excess fresh oil vapour through steam-jacketed vaporizer 42 and pipe 43, and are withdrawn at 36 for refining and separation.  The oil-water condensate from condensers 21, 30 and trap 23, is transferred by pipe 22 to separator 54, the water is separated and passed to tank 56 and may be re-cycled to make up the alkaline solution from actifier 12 through line 58 and pump 59 while the oil is separated and passed to tank 60 and may be drawn off through line 62 for use as fuel. The oil-water condensate from condenser 35 is separated in separator 40 and the water is discarded while the oil passes to tank 47.  Live steam may be used to help vaporize the oil. In a modification the steam jet evacuator may be placed before the condenser 21 or after the ammonia scrubber 25.  Also the scrubber 25 may be omitted if desired.  In a further form three vaporizers for oil are used instead of two.  In another modification in which hydrogen cyanide is not recovered two jet evacuators are used instead of a jet evacuator and a pump.  Specifcations 190,115, [Class I (ii)], 612,122, and 675,348 are referred to.
