Filed: 1936-05-25
Abstract: 475,139. Making shelves. EVANS, W. J. May 25, 1936, No. 14658. [Class 83 (ii)] [Also in Group XIV] A shelf is constructed from a single piece of rigid sheet material, such as sheet-metal or fibre board and comprises one or more flanges bent therefrom at its rear edge for attachment to a wall, and a web bent downwardlv therefrom at either or each end of the shelf and serving as a stay or stiffener. A shelf 1, Fig. 2, is bent up from a sheet blank, and comprises a flange 2 with slots 3 to receive securing screws, and webs 5 forming stays and stiffeners. Flanges 5a receive further securing screws. The edge 7 of the shelf is turned downwardly, and is formed with a retaining rib 8. The inclined edges of the webs 5 are formed with beads 6, adjacent shelves being assembled with the beads 6 interlocking. Alternatively, or in addition, adjacent webs are bolted together. In a modification, one web is replaced by a small lip 9, Fig. 4, which may be bolted to an adjacent web 5. The line 10, Fig. 5, about which the blank is bent to form the web 5 may be inclined, so that adjacent shelves may be connected at an angle to each other.

Converting pulsating currents into steady continuous currents.-In means for supplying wireless &c. apparatus with steady current from the mains 1, 2, there is provided in addition to the usual smoothing arrangements a pair of chokes 6, 7 and a pair of condensers 8, 9 connected in series, the point of interconnection of the condensers being earthed. In the case of A.C. mains the arrangement is introduced into the secondary circuit of the supply transformer 3 as shown, the transformer being mounted in the same casing as the chokes and condensers. The transformer is made interchangeable, and is constructed so that its core normally operates at saturation. The chokes are wound on supports 6, 7 mounted over the condensers and are separated by a metal partition 22. A similar partition 17 separates the transformer from the chokes and condensers, the partitions forming the point of interconnection of the condensers and being connected to an earth terminal 28. A metal cover encloses the whole assembly. Alternatively, the parts may be combined with the apparatus to be supplied with steady current.

Abstract: 319,383. Gee, W. J. May 23, 1928. Variable-speed gearing of the kind comprising a complete screw or worm gear 3, Fig. 1, meshing with a like gear 5 which is made up of segments 4 which yield in an axial direction to modify the speed ratio, as described in Specifications 115,857 and 130,174, is operated by power-means forming an alternative to the control-means described in Specification 245,250. Each segment 4 has an extension 9 with pillar 10 and ball 12 engaged by two races 6 fixed in an annular holder 7. The holder 7 pivoted diametrally on pins 8 is tilted to vary the amount of slip in the gearing by a toothed segment engaged by a rack as described with reference to Fig. 3 of Specification 260,065. This rack 34, Fig. 5, has other rack teeth 37 engaged by a single tooth 38 on a boss 39. In order to change speed, the boss 39 is disengaged by hand, and re-engaged with the next tooth of the rack 37. The rear flat face 39<1> of the boss 39 is now inclined. The power-means brings an impeller ' 49 down on the face 39<1> so as to turn it flat and so move the rack 34 and tilt the holder 7. The shaft 1, Fig. 5, which is either the driving or the driven shaft of the gearing, carries a trigger 66 which trips a lock so as to cause a bolt 50 to shoot out. A cam 64 on the next revolution strikes the bolt 50 and so thrusts the impeller 49 against the face 39'.

[Class 110 (iii).] The supply of steam to a turbine driving a boiler-feed pump is controlled by the discharge pressure of the pump. A control valve 13 has three pistons 18, 19, 20, and upon upward movement due to the pressure of a spring 5, allows steam which enters a port 22, to flow in succession to nozzles 29, 32 and 31, and 30 through ports 201, 191, 181 and 19<2>. The pump discharge pressure acts upon the top of a plunger 2 to press the valve 13 downwards against the spring 5. Nozzles 27, 28 are open directly to the port 22. A hand-controlled valve 33 covers two further nozzles 34, 35. The pistons 18-20 may be loose discs on the valve spindle and move in cages provided with valve seats. The lower end of cylinder 2 is open to atmospheric or other datum pressure. Steam from the port 22 has access to each end of the valve 13. The laps of pistons 18-20 are so arranged that the greatest laps cover the greatest pressure differences, to reduce the steam leakage past the pistons.
