Title: Improvements in or relating to circular looms
IPC: D03D37/00
Filed: 1935-12-23
Abstract: 469,475. Circular looms. BRITISH CELANESE, Ltd., HALE, F. C., and YORKE, J. R. Dec. 23, 1935, No. 35560. [Classes 142 (i) and 142 (ii)] Relative movement between the shuttles and the warp of a circular loom is brought to an end when a weft controlled rod 29 is pushed through the warp sheet 27 and displaces a feeler 30 connected with the stop mechanism. The weft 8 passes from a spool through an adjustable tensioning device consisting of twospring-pressed smooth discs 14 and thence through eyes 10, 11 to the fell. Between the discs 14 and the eye 10 a guide 21 carried by a bell-crank 18, 19 rests on the weft 8. On weft failure a spring 181 turns the lever 18, 19 and frees the arm 22 of another lever 22, 23 which is then turned by a spring 25 until the arm 23 engages the warps 27 whereby it is turned further and moves the rod 29. This extra motion of the arm 23 is allowed for by a spring 32 which normally holds the two parts of the lever 22, 23 in the relative position shown in Fig. 3. Specifications 402,822,413,376, 424,789, and 463,484 are referred to.

Abstract: 375,715. Combined turning, boring, and milling machines. KEARNS & CO., Ltd., H. W., Broadheath, near Manchester, and KEARNS, J. R. C., Orrish Meres, Harboro Road, Ashton-on-Mersey. Dec. 29, 1931, No. 35888. [Class 83 (iii).] Boring-bar machines.-A combined horizontal boring and milling machine has alternative constant speed and variable speed drives for the feed mechanism either of which may operate through a common change speed feed gear. The main driving pulley 1 rotates either the wheel 8 or the wheel 5 in the forward or reverse direction, respectively, according to the position of the clutch 3, thus driving through helical gears 10, 11 the shaft 12 which extends upwards from the bed a to the vertically sliding head d, Fig. 2. The shaft 15 driven by helical gears from shaft 12 drives the main change-speed gear (not shown) by means of which the spindle e is rotated at various speeds. The drive for the feed mechanism is taken either through wheels 16, 17 from the shaft 12, or from spindle e through wheels 20, 22 according to the disposition of the dog clutch 23, thus allowing for constant speed and variable speed feeds respectively, the common reversing and change speed mechanism completing the train to the shaft 25 from which the feed motions for the various movable members, such as the table b, are taken. An end-forcing slide may be fitted to the head and fed by either the constant speed or variable speed source.

Title: Process for the production of very pure gallium
IPC: C22B58/00
Filed: 1957-11-20
Abstract: 816,282. Gallium preparation. BROWN, BOVERI & CIE A.G. Nov. 20, 1957 [Nov. 21, 1956], No. 36135/57. Class 82(1) Gallium of high purity is prepared by converting technically pure gallium into an organic compound such as gallium tri-ethyl, gallium tri-isopropyl or gallium tri-isobutyl, which is then decomposed to the metal by ultra-violet irradiation. The organic gallium compound is preferably purified by fractional distillation and may be decomposed pure or dissolved in ethyl ether, tetrahydrofuran or dioxan. As shown, gallium tri-ethyl V, is fed to the vessel G via the pipe E together with an inert gas such as hydrogen, nitrogen or argon and is decomposed by the ultra-voilet radiation emitted from the mercury vapour lamp B, the gallium collecting at Ga to be drawn off through the tap H. Separation of the gallium is facilitated by the stirrer R and by heating the gallium tri-ethyl to a temperature below that at which thermal decomposition begins.

Abstract: 1434802 Fluid-pressure servomotor systems TEMPMASTER CORP 30 July 1973 [26 Jan 1973] 36164/73 Heading G3P [Also in Division F4] Fluid-flow through a duct 12 is controlled by a damper 26 biased to open position and actuated by a bladder 34 controlled by a bleed means 80. The duct may be part of a ceiling system supplying heating, cooling or ventilating air from an inlet 16 to a diffuser 20. A U-tube 42 having one end disposed within the inlet is connected by a flexible tube 36 and a filter to the bladder 34 which is also connected to the bleed means through an adjustable restrictor and a bleed port.

'[Classes 110(i), 110(iii) and 122(v)] In a labyrinth packing for a rotary type of fluid-pressure apparatus particularly intended to operate at high linear speeds in which a series of axially spaced annular discs interact between the stator and a ring to provide a tortuous passage for pressure fluid, the ring is rigidly supported from the rotor by a pair of separate supporting discs fast with the rotor and secured to the ring, at least one of the supporting discs being conical and disposed concavely to the other. The packing comprises a series of discs 17 carried by a stator ring 18 and secured by rivets 19. The inner peripheries of the discs co-operate without contact with the stepped surface 20 of a ring 21 carried from the rotor 11 by a pair of supporting discs 23, 24. The latter are preferably of high tensile steel and are shrunk on a drum 25 of high thermal expansion steel bolted to the rotor. Driving dogs 27 are disposed between the supporting discs, and the disc 23 has additional driving dogs 28 intermeshing with driving dogs 29 on the rotor blade supports 12. The pressure fluid acting against the inner supporting disc 23 will serve to balance the axial thrust on the rotor blades. The discs 17 may alternatively be secured to the ring 21, or some of the discs may be secured to the stator ring 18 and the others to the ring 21. Specification 608,978 is referred to.

Abstract: 1503660 Rock drills; clamping drill rods VICTOR PRODUCTS (WALLSEND) Ltd 20 Aug 1975 [20 Aug 1974] 36603/74 Headings B3C and B3N A rock-drilling machine includes a clamping device adjacent the feed path of a drill rod 5, 6 for clamping a rod section 6 so that a new rod section 5 can be screwed to it at junction 14. The device comprises a gripping surface, Veeblock 12, Fig. 3, located alongside the surface of the rod section 6 and means, rotatable cam 26, for bringing the drill rod into jamming engagement with the gripping surface. In particular, the Vee-block and cam are supported between plates 16A, 16B pivoted on a plate 23 via a rod 19 in oversize hole 21 which allows transverse play. The pivotal movement ensures improved jamming of the Vee-block and cam on the rod at point 30A, 30B or 30C, 30D if the rod moves longitudinally, e.g. due to its weight, but the movement is limited, to prevent inadvertent jamming, by adjustable stops 22. The play of rod 19 in hole 21, allows the clamp to move transversely to the rod to reduce the rods displacement. The cam is rotated by handle 28 and the rod may be guided at 7.
