Patent GB-697714-A (GB)
Title: Improvements in or relating to sediment handling or agitating devices
IPC: B01D21/06
Filed: 1952-02-13
Abstract: 697,714. Gravity-separation apparatus. HARDINGE, H. Feb. 13, 1952 [Feb. 17, 1951], No. 3808/52. Class 46 A settling-tank of the kind having scrapers rotating about a vertical axis and conventional in general design i s characterized chiefly by the provision of a combination thrust - and - radial bearing assembly disposed between an annular supporting member and an annular portion of a gear-wheel driving the scraper shaft to prevent tilting of the shaft. A hollow torque shaft 30, Fig. 3, is driven indirectly by a worm-gear-wheel 56 in a casing 46 supported on cross-beams 44. The casing 46 has an upstanding annular portion 52 having a seat 54, Fig. 8, to which is clamped by members 76 and bolts 78 the inner race 66 of a thrust-and-radial bearing assembly 64. The outer race 66a of the bearing assembly is similarly clamped to a seat 58 in the underside of the wheel 56 where the wheel is shaped to form an offset flange 60. Rotation of the wheel 56 is transmitted through a drive tube 90 secured to the flange 60 and having cam slots 98, Fig. 5, engaging rollers 102 on a shaft 100 extending through the upper end of the torque shaft 30. When rotation of the shaft 30 is impeded by engagement of the scrapers with an obstruction in the tank the drive tube 90 continues to be rotated by the wheel 56 and as a result the rollers 102 ride up the cam slots 98, the scrapers in turn being lifted over the obstruction. Excessive rise of the shaft 30 brings about engagement of an extension 104 on the shaft 30 with. a switch 114 to cut off the current to an electric motor driving a worm 80 which engages with the wheel 56. The switch 114 may also sound an alarm. The extension 104 slides in a bearing sleeve 108 in a cover secured to the drive tube 90 and threads into the boss of a hand-wheel 116 by which the scrapers may be raised or lowered and their height adjusted. Peripheral openings (not shown) are provided in the flange 60 to permit access to the bolts 78 when the drive tube 90 is removed. Tilting of the torque tube 30 is substantially prevented by the bearing described and additionally by the bearing sleeve 108, a construction 96 in the drive tube 90 and a lower guide bearing 118, Fig: 3. The bottom and side walls of the casing 46 form an oil-bath 50 for the worm and wheel. A yieldable seal 122 prevents ingress of liquid, solid or vapour into the casing 46 and wipes the tube 30 when it is raised. In the modification of Fig. 8 the mechanism for raising the tube 30 is dispensed with; the flange 60 is extended inwards to 124 and is connected by bolts 126 with a sleeve 128 which extends downwards a short way below the casing 46, its lower end being connected to the upper end of the tube 30. Apertures 130 provide access to the bolts 78.

Abstract: 100,226. Aktiebolaget Svenska Kullagerfabriken. March 31, 1915, [Convention date]. Ball bearings.-To render the ball tracks in a ball bearing symmetrical at the junction of a lateral filling-opening, the opening is extended across the track either wholly or partly to the opposite sides of the race rings. The filling-opening is either cylindrical and parallel to the axis of the bearing, or is curved towards the axis as shown in Fig. 3, or away from the axis. As an alternative, the opening in one race ring may be convex as shown at 1, and that in the other ring straight; or both may be convex. Fig. 14 shows a modification in which curved openings 1, 2 have cylindrical extensions adjacent to and extending beyond the centres of the ball tracks.

Abstract: 1,026,972. Intermittent feed mechanism for cine apparatus. EASTMAN KODAK CO. Jan. 31, 1963 [Jan.31, 1962], No. 4119/63. Heading G2E. A device for converting continuous movement at a perforated film 14 into intermittent movement comprises a stationary detent 50 for successive engagement with the perforators 12 to interrupt the movement of the film such that the film takes on a double reverse curve and finally disengages from detent 50 and straightens due to its resilience; the cycle then repeats. As applied to the cine projector at Fig. 1 sprocket 10 is continuously driven and engages film 14. Film-guide 18 has gate 20 and comprises two flat members 30, 32 which have curved positions 36, 38 to form offset chambers 46, 48 to receive the curved film before disengagement with detent 50. The film is not pulled from guide 18, and a free loop is formed to remove any tension. The direction of film motion may be reversed and in another embodiment, film-guide 18 is turned through 90‹ A conventional shutter is unnecessary. The film may move at 400 frames per second. A single sprocket may be used to feed the film into and out of the film passageway used.

Patent GB-396796-A (GB)
Title: Process for the production of ethers of cellulose esters
IPC: C08B13/00
Filed: 1932-02-12
Abstract: A cellulose ester or mixed ester is reacted with an oxyalkylating agent in the absence of strong inorganic bases such as caustic soda under such conditions that no substantial saponification of the cellulose ester occurs.  The reaction is preferably effected in the absence of bases, particularly when alkylene oxides are used as oxyalkylating agents, but ammonia or organic bases may be present in proportion insufficient substantially to saponify the ester groups. The cellulose ester may be a fatty ester such as the acetate, propionate, butyrate, laurate, oleate, or stearate, or a benzoate, or a mixed ester containing both acetate radicles and radicles of higher fatty acids.  Esters containing the CSS group are excluded.  The oxyalkylation may be effected in the liquid or gaseous phase, with or without inert liquids or gases, and if desired under pressure. The products may be employed in the production of artificial silk, films, varnishes, plastic masses, moulding powders, and the like. In examples, (1) cellulose acetate containing 2 to 2,5 ester groups is heated in an autoclave with ethylene oxide, (2) cellulose acetate stearate containing 1,5 to 2 acetate radicles and a small proportion of stearate radicles is treated with butylene oxide under pressure, and (3) cellulose benzoate containing 1,5 to 2 ester groups is reacted with propylene oxide in the presence of oxypropylmethylamine. Specification 326,861, [Class 2 (ii), Cellulose &c.], is referred to.

Directing and adjustably supporting endless belt conveyers; portable conveyers.-In a device for the removal of ashes and the like by a conveyer dipping into a water trough the water trough is arranged so as to be movable to facilitate repair. As shown in Fig. 2 the trough a is capable of swinging on the shaft b of one of the guide rollers of the endless belt conveyer d so that it can be swung together with the conveyer away from the outlet funnel f, which is then closed by a damper c. Fig. 3 shows the trough a arranged on a travelling frame o which is raised off the floor by screws e when in position so that the trough contacts with the ash funnel, to which it may be secured by screws. In this form also the trough may be pivoted to the frame o at b so that it can be swung downwards to clear the ash funnel when the frame is lowered and moved away. Alternatively the ash funnel may be bodily lowered on to the trough a and removed therewith. In a further modification a long trough is provided receiving ashes from several funnels and movable by means of hangers on rails.
