A fluorescent lighting unit comprises an elongated trough shaped casing housing refractors on its opposite side walls, a top cover and means for supporting fluorescent tubes of the type including a coating on the surface of the tube extending over a longitudinal zone which reduces the light intensity over that zone but increases it over another longitudinal zone, the zones of increased intensity being directed to shine light through casing and refractors so that the major part of the illumination is directed outwards and downwards. The fitting may comprise a shallow cover 2 provided with an enlargement 4 to receive the end of a supporting member 3 in the form of a tube, and a transparent trough shaped casing 1 secured to the cover by a frame 7. Three fluorescent tubes 13, 14, 19 are supported within the casing, each having a part 23 coated with material reflecting ultra-violet light e.g. over an arc of slightly more than 180 degrees and are arranged so that the major part of the increased light from the uncoated zones 24 falls on refractors 31 and 32 in the case of the tubes 13, 14 and a pair of refractors 36, 37 in the case of the tube 19. Refractors 36, 37 may be replaced by a reflector of elongated V-shape and reflectors may also be used in addition to the reflectors 31 and 32.

Abstract: 775,552. Feeding webs. UNITED STATES STEEL CORPORATION. May 3, 1954 [Dec. 4, 1953], No. 12841/54. Class 100(1) An apparatus for accumulating a surplus of strip material for feeding while changing a roll from which the strip is unwound, or on which the strip is rewound, comprises a plurality of rollers mounted on fixed axis and a plurality of rollers mounted on a vertically slidable frame, the strip being looped around the rollers one or more of which are rollers which centre the strip on the rollers. As shown, rollers 48 are rotatably mounted on a carriage 34 having a guide 32 slidable along guide posts 30, while rollers 46 are rotatably mounted on fixed axes, such that the strip S forms loops around the rollers 48, 46. The carriage is attached to wire ropes 36 passing over guide pulleys 40, 42 and carrying counterweights 38. The strip S passes around a narrow-bodied roller 8, i.e. a roller having a strip-supporting surface of less width than the strip, then around a centring roller 44 which may, as described in Specifications 709,908, 717,671, or 735,561 or preferably Specification 775,551 and is then looped around the rollers 46, 48. The rollers 48 are preferably centring rollers similar to the roller 44, while the rollers 46 are narrow-bodied rollers. Rollers 50 and 52 on the exit side of the rollers 46, 48 correspond to rollers 44, 8. When it is necessary to change a supply roll of strip 3, sufficient strip will be accumulated in loops around the rollers 46, 48 to permit strip to continue feeding to a treating apparatus beyond the rollers 46, 48. When the supply roll has been attached, the feed on the entry side of the rollers 46, 48 is speeded up until the carriage 34 returns to its upper position. In a modification, Figs. 5, 6, and 7, not shown, the rollers on fixed axes are mounted above rollers on a vertically slidable counterweighted carriage which descends to take up slack which develops when the strip is stopped beyond the accumulating apparatus.

Title: Improvements in or relating to Foot Cycles and Roller Skates.
Inventor: LUCAS AUGUSTE RENE
IPC: B62M1/00
Filed: 1917-09-07
Abstract: 110,347. Lucas, A. R. Oct. 12, 1916, [Convention date]. Foot-cycles.-Two rollerskates are connected together so as to follow given paths by a frame with a steering-device, and are provided with free-wheel mechanism to prevent them from moving backwards, so that a point of support on the ground is ensured in order that an impulse may be imparted to them for the forward movement. As shown in Figs. 1 and 3, the two skates a can move parallel to each other on the longitudinal members of a frame b, which is provided at the front end with a steering-wheel b<2> and at the rear end with a loose bearing-wheel b<1>. Rollers a<2> at the ends of the sole-plates a<3> run on the longitudinal members. The roller a' of the skate is keyed to a spindle pivoted in vertical brackets a<5>, and a spring-pressed pawl a' on one of the brackets engages a ratchet-wheel a<6> on the spindle to lock the roller a<1> against backward movement. A free-wheel device is provided on either or both skates. To facilitate turning, the pawl a', Fig. 5, can be disengaged from the wheel a<6> by depressing a spring-pressed stud c against the tail a<9> of the pawl. In a modification, the roller a<1>, Figs. 7 and 8, is supported in the bracket a<5> by means of an eccentric trunnion d<1>. and a concentric brake drum d is keyed to its spindle. When an effort is exerted on the skate to cause the roller a<1> to roll backwards, the eccentric d' moves on its axis and the drum d<1> rubs against an adjustable brake-band d<2>. Instead of a rigid frame b, the skates may move on two parallel sides of a pivoted parallelogram. The skates may be forced to follow curves of small radii. A three-wheel vehicle may be employed, the trailing-wheel constituting the steering part.
