Title: Improvements in or relating to means for feeding fabrics
IPC: B29D30/00
Filed: 1929-04-13
Abstract: 333,542. Dunlop Rubber Co., Ltd., and Willshaw, H. April 13, 1929. Divided on 334,925. Feeding webs. - In web-feeding apparatus in which the web hangs in a loop between feeding devices operating at different speeds, and a member resting in the loop actuates trip devices for controlling the stopping and starting of the feeding device supplying the loop, the trips operate or include one or more electric switches which control (a) a clutch in the feed drive or (b) a motor driving the feed supply device. The apparatus is particularly for use in feeding rubber strip, or rubberized fabrics such as are employed in making tyres. In one form the web 1 is fed to a loop 5 by a feed roller 4 which is normally driven so as to supply the web at a greater rate than it is withdrawn by the web-using apparatus. A roller 6 resting in the loop and carried by endless chains 11 is guided in slots 9 in the frame 8 and is adapted, at the limits of its movements, to actuate a pair of arms 16, 17, pivoted to the frame 8. The arms 16, 17 are connected by a link 15 engaging a lever 19 adapted to actuate alternately a pair of switches 22, 23 to control circuits adapted respectively to stop and start the feed roller 4 either by controlling the feed drive motor or by controlling a solenoid for actuating a mechanical clutch in the drive to the roller. In another form, the roller 6 directly actuates a switch at each end of its travel. In this form also the chains 11 are dispensed with. If the fabric is provided with a lining web, the feed roller 4 may be omitted, the web with its lining passing over guide rollers and the lining then passing separately to a rewinding reel driven and controlled similarly to the roller 4, the web thus being fed to the loop by the pull on the lining material. In any of the forms described a safety switch may be arranged above the upper trip device, adapted, if the upper trip should fail to act, to be operated by the roller 6 to stop the drive of the device withdrawing the web from the loop.

Filed: 1921-02-16
Abstract: 159,503. Boella, C. March 2, 1920, [Convention date]. No Patent granted (Scaling fee not paid). Gear-cutting.-In a machine for generating or correcting involute or other spur gear teeth the blank-spindle is mounted in a slide 4 traversed along a guide 5 and rolling motion is imparted to the blank 1 by means of a master gear 3 mounted on the blank-spindle and engaging a rack consisting of a fixed part 6 and a slidable spring- pressed part 7, the sliding motion being limited by a pin 9 and slot 10. In this way, one toothface of the master gear is kept in firm engagement with the tooth-face 6<11> of the fixed rack while the milling-tool 11 generates the corresponding tooth-face on the blank. Indexing is effected by means of a supplementary tooth 13 which may be automatically moved into the path of the blank after the latter has been moved clear of the rack by means of the mechanism shown in Fig. 3. The supplementary tooth is slidably keyed on a shaft 14 and at a predetermined point in the travel a stop 17<11> on the sliding member 4 engages the arm 17 to reverse the spring toggle and bring the tooth into operative position. On the return stroke, the tooth is withdrawn by the engagement of a second stop with the arm 18. The opposite tooth faces may be cut by reversing the blank on its spindle, or alternatively another double rack may be employed in conjunction with a seeond tool 11. A planing-tool of the rack-tooth type may be employed instead of a milling- cutter.

Title: Improvements in or relating to the purification of gases
Inventor: TREMAINE JOHN FREDERICK
IPC: B44D3/18
Filed: 1952-03-07
Abstract: An inert gas or gas mixture, e.g. nitrogen, argon, helium, krypton, or xenon, or mixtures thereof, is purified from either oxygen or hydrogen by mixing the impure gas with an amount of hydrogen or oxygen approximately equal to that required to convert all the oxygen or hydrogen present in the impure gas to water and effecting the conversion by passing the mixture over a catalyst consisting of a mixture of manganous oxide (MnO) and manganous-magnanic oxide Mn3O4 at a suitable temperature, e.g. above 300 DEG  C., which catalyst is adapted to react with and remove any excess of either hydrogen of oxygen which may remain after the conversion.  The conversion may be effected at, say, 120 atm. pressure.  The hydrogen or oxygen addition may be controlled so that there is alternately an excess and a deficiency of hydrogen relative to the amount required to convert all the oxygen present to water, and the periods during which the process is operated with such excess or deficiency are such that the catalyst is at all times capable of removing an excess of either oxygen or hydrogen.  If the impure gas has a high content of oxygen or hydrogen, e.g. more than 3 per cent., excessive reaction heat may be avoided either by reducing the impurity content by recirculating with the entrant gas a proportion of the gas already purified, or by carrying out the catalytic conversion in two or more stages with separate addition of part of the total hydrogen or oxygen necessary before each stage and cooling the gas between stages.

Abstract: 622,024. Vehicle suspensions. FORD MOTOR CO., Ltd. March 3, 1947, No. 6022. Convention date, March 14, 1946. [Classes 108 (ii) and 108 (iii)] A torsion rod suspension for a vehicle is characterised by one end of the torsion spring 32 being so mounted on a frame member 16 as to be held against rotation but able to slide freely in a lateral direction, such sliding occurring between two surfaces at least one of which is plane. The torsion rod 32, Fig. 3, is at one end attached by an integral flange 33 to a wheel-supporting arm 22, and at the other end formed with an integral arm 35 whose outer surface 36, Fig. 4, is cylindrical. A block 45 with a concave surface 46 receives the arm 35 and is free to slide laterally on the upper flange 41 of the frame member 16 between the webs 40, 42 thereof. The end 37 of the lever 35 engages the rounded end of an adjusting bolt 47 which turns in a nut 48 fixed between the webs 40, 42. In a modification, Fig. 10, the squared end 77 of the torsion rod is received in a rectangular hole 78 cut in a cylinder 79, and can move longitudinally and vertically relative thereto..An arm 81 welded to the cylinder carries an adjusting bolt 82. The sliding block 84 carries a pin 87 guided laterally in a slot 88 in a bracket on the frame member 86. The block 45, Fig. 4, could be similarly guided, or the pin replaced by a bolt so that the block could be clamped in a selected position. In another construction, Fig. 11, (not shown), the sliding block is dispensed with, and the cylinder 79 slides directly on the frame member, and is restrained from longitudinal movement by a lug on the frame member.
