Title: Yarn fault detector installations
Inventor: HORTON LEE TREVOR
IPC: D04B35/14
Filed: 1983-08-18
Abstract: A yarn fault detector installation has a plurality of lever means (2) each for guiding a yarn. The lever means (2) are actuated individually in the event of a yarn fault. Baffles (4) are attached to the lever means (2) and can cut a beam of light transmitted through a tube (6) which is detected by a detector (10) when the appropriate lever is actuated, so causing the baffle to move into a slot (36) in the tube (6). Each lever means (2) includes a first lever (14) biased upwardly by an even-centre spring (18), and a second lever (22) coupled to a baffle (4) and resting, when in normal use, on the thread supported by the first lever (14). Excessive tension in the thread will cause the first lever (14) to spring into a downwardly-biased position, allowing the second lever (25), together with the baffle (4), to fall into the alarm position. A yarn break, irrespective of whether preceded by excess tension, will similarly release the second lever (25) to fall to the alarm position. An extension of the baffle (4) may protrude through a slot (40) to give a visual warning and to enable the faulty yarn to be identified. <IMAGE>

Patent GB-2141648-A (GB)
Title: Abrasive finishing of door surfaces
Inventor: HUNDEBOL KELD OTTING
IPC: B24D/
Filed: 1984-05-09
Abstract: When sanding e.g. panel doors (12) in a machine, the doors are placed under six horizontal sanding spindles (10) with sanding members (11) which rotate and are moved around a vertical driving cylinder (19). The spindles (10) are mounted in such a way that they can be programmed to rotate in a given direction and if necessary be completely disengaged. This programming is done by placing cams (17, 18) for engaging and disengaging the spindle (10) by vertical movement of a friction cone (8) on the spindle between an upper and a lower friction path (6, 7) on the side of the driving cylinder (19). Improved sanding is obtained as the doors (12) are engaged by sanding threads from many different sides thus eliminating sanding traces. Furthermore, the machine can be adjusted to the shape of the work piece, whereby it is possible to adapt the sanding operation individually according to the work piece and also to stop the sanding e.g. when the sanding members move across sharp edges on the work piece, said edges therefore remaining quite sharp as they are not exposed to any sanding. <IMAGE>

Title: Improvements in ammonia synthesis processes
Inventor: HIDAKI MORIHISA
IPC: B01D53/04
Filed: 1984-08-14
Abstract: A process for the synthesis of ammonia involves reacting hydrogen and nitrogen at a synthesis pressure of 120 kg/cm<2>G or lower in the presence of a catalyst in a reactor (2) to form a product gas containing hydrogen, nitrogen and ammonia. The product gas from the reactor (2) is fed through an adsorbent bed (4A) in order to adsorb ammonia onto the bed. Concentrated gaseous ammonia is then subsequently desorbed from the adsorbent bed (4A) separately from the nonadsorbed components of the product gas, and the desorbed gaseous ammonia is cooled in a liquefier unit (6) to obtain liquid ammonia by condensation. The residual product gas remaining after ammonia separation is recirculated to the synthesis reactor (2). In the bed (4A), ammonia is collected and recovered by thermal swing adsorption-desorption, but in other embodiments of the invention pressure swing adsorption-desorption is employed. <IMAGE>

Patent GB-2171478-A (GB)
Title: Rotary fluid couplings
Inventor: BRAKE ARTHUR LEIGHTON
IPC: F16L27/08
Filed: 1985-02-11
Abstract: A rotary fluid coupling comprises a stationary housing (12) and a rotary member (14) journalled in bearings (38). Pressure in a passage (16) will tend to bias the rotary member to the right, but this is balanced by fluid pressure acting within a pressurised balance chamber (70). This acts upon a floating member (60) which transfers an equal and opposite force to the rotary member (14) by means of a circlip (64). There is thus no resultant force on the bearings (38) whatever the internal pressure. <IMAGE>
