Title: Method for mercerising cellulosic fabrics with liquid ammonia
IPC: D06M11/00
Filed: 1971-12-23
Abstract: 1365706 Mercerizing with liquid ammonia CLUETT PEABODY & CO INC 23 Dec 1971 [14 Jan 1971] 59987/71 Headings D1L and D1P Cellulosic e.g. cotton fabric is mercerized with liquid ammonia without substantial shrinkage by: advancing continuously a web of the fabric in turn through an impregnating station and a removal station; impregnating the web with liquid ammonia at the impregnating station, and removing the ammonia from the impregnated web, the residence time between application and removal of the ammonia on any region of the fabric being from 0.6 to 9.0 seconds, preferably 2.5-7.2 seconds. This residence time may be controlled by regulating the speed of advance of a cellulosic fabric web between impregnation and removal stations and by heating the web to dry it. A mercerizing apparatus shown in Figs. 1 and 2 comprises an insulated treatment chamber 12 maintained at a reduced pressure by exhaust means in communication with a vent 28. A fabric web 11 is advanced continuously through the chamber and passes via a seal 14 and rollers 15, 16 through a trough 17 containing liquid ammonia. The trough has a float 18 connected to a microswitch 19 which acts via a solenoid 21 to operate a valve 22 in a supply line 23. The impregnated web passes over a bow roller 32 (see Fig. 2) which spreads and smoothes the web prior to its passage between squeeze rollers 33, 34. Liquid ammonia removed from the web at this stage is returned to the trough via a pan 36. The web passes over a further bow roller 35 into a dryer 13 wherein the web is conducted on a heated blanket 38 over a drum 39. The blanket is endless and is cycled by means of rollers 41 over a heated drum 42. The web is conducted by rollers 43, 44 out of the chamber via a seal 45, for further processing. In an alternative embodiment, Fig. 3 (not shown) the roller 16 is replaced by a larger roller (16a) co-operating with a heated can (46) the web passing under the roller (16a), for immersion in the liquid ammonia between the roller and can, and over the can for removal of the ammonia. The bow roller 32 and squeeze rolls 33, 34 are omitted. Impregnation of the web may alternatively be by spraying. The process reduces the need for applying weft-wise tension to the web.

Abstract: 1397064 Rope fire escape W H FLOWERS 15 May 1972 [24 Feb 1971] 61369/70 Heading A5A [Also in Divisions B8 and F2] Apparatus for making a controlled descent of a rope or other flexible element in the event of fire in a building comprises a slide member 10 having a passage therethrough for flexible element 11 and formed with means 35 for attaching harness 15, the slide member being provided with means for exerting a frictional grip on 11, and the attachment means 35 being arranged such that, in use, the weight of the person in the harness biasses the slide member from the vertical so that a further firictional force is thereby exerted on 11. As shown in Fig 1 rope 11 is attachable by eyelet 12 to hook 13 permanently secured to building 14 adjacent a window or other opening. Harness 15 comprising adjustable waist strap 16 and seat strap 17 is attachable by hook 19 to flat metal lug 35 on slide member 10. The latter comprises, Fig 2, metal T-shaped body 20 formed with main and branch tubes 21, 22, main tube 21 having cylindrical bore 23 for the passage of rope 11, and branch tube 22 having a screw-threaded bore engaged by handle 24 with hand grip 25 at its outer end. Pressure member 27 in the form of a steel plug is mounted in the inner end of bore 26 in handle 24, and its inner face 28 is urged into contact with rope 11 by spring 29 acting on slidable tube 30. The outer end of spring 29 is engaged by screw-threaded plug 32 formed with head 34 for manual adjustment of the frictional force exerted on rope 11 by plug 27. Body 20 is also provided with lug 35 formed with circular holt 36 for engagement by hook 19 of harness 15, lug 35 being positioned so that the weight of a person in 15 inclines body 20 to the vertical in a modification an enlarged lug may be formed with further holes 36a, 36b providing alternative engagement points for people of different weights.

Abstract: 1332488 Recording and playback; digital data storage TELETYPE CORP 29 Dec 1970 [30 Dec 1969] 61502/70 Headings G4C and G5R Coded information pulses are recorded in precise positions on a record by using signals picked up from a clock track on the record, a delay signal being generated to stop the movement of the record before the next clock signal occurs. Whenever information is received by a storage register 50, a control 42 is activated to allow a motor 28 to drive a tape or disc record 23 through a clutch/brake unit 30. A clock pulse 84 thereupon picked up by a playback head 16 is fed to a control 70 which then causes the stored information to be passed to write amplifiers 52 and hence to recording heads 12, 14, 18, 20 for recording. The clock pulse also causes the control 70 to activate a delay timer 85 which, after the delay, causes the register 50 to clear, and also the control 42 to operate unit 30 to stop the record.

Patent GB-2016270-A (GB)
Title: Improvements in and relating to fire extinguishers
IPC: A62C13/74
Filed: 1978-07-15
Abstract: A discharge control device is in the form of a unitary head assembly having a handle and spring loaded operating lever which can be squeezed against the handle when discharge is required. A locking pin prevents accidental operation and has to be withdrawn before discharge can be effected. The head assembly is adapted to be connected to the screw threaded end of a gas cylinder containing appropriate gas under pressure. A piercing member 60 is driven in a downward direction to break the membrane seal which normally closes the gas cylinder and simultaneously the operating lever moves a valve closure member 36 off a conical seating 34 to allow the pressurised fire extinguishing medium to leave the discharge nozzle. In the event that the contents are only partially required to extinguish a blaze, the operating lever can be released and this immediately allows the valve closure member to seal off the nozzle from the pressurised interior. <IMAGE>
