Abstract: 694,378. Roofs. BLUMFIELD, C. V. May, 15, 1951 [Nov. 30, 1950], No. 29405/50. Class 20(iv). Arched lattice type roofs of lightweight construction e.g. for hangars &c. comprise braced girders 11 which are first erected on supporting posts or formed as end walls of the building and a lattice construction including longitudinal members 10 made e.g. of steel or aluminium tubing, timber &c. pairs of transverse members as 12, 13, and four groups of diagonal bracing bars 14 which are assembled on to temporary girders on the ground and then raised and secured to the girders 11. The temporary girders are then removed. Slotted U- section members, Fig. 4, may replace the pairs of transverse members 12, 13. The members 10, 12, 13, 14 are joined where they meet by bolts 16, Fig. 2, bolts 15 being used to join the members 10, 14 .and 11. The bracing members 14 may be made wide enough to accommodate two bolts 16 at each junction, alternatively, they may be fitted with gusset plates. A lower layer of bracing members parallel, or inclined, to the members 14 may be added to pass between the members 10 and the lower transverse member 13, alternatively the bracing members may be formed of short lengths of tubing which are splayed at their ends and are welded to the longitudinals 10. Spacing clips 17, Fig. 3, may be used to strengthen the construction and embrace spaced pairs of members between the longitudinals 10. The transverse and diagonal members may be angularly bent at intervals instead of being curved, and glazing may be provided between the transversemembers, the diagonals being omitted where necessary. The roof may have inner and outer coverings and a concrete filling, shuttering for the latter being erected from the inside of the roof.

Abstract: 643,894. Electric motors. SIEMENS BROS. & CO., Ltd., GACHET, E. J., HARDS, E. J., and CHRISTIAN, D. A. Nov. 21, 1947, No. 30929. [Class 35] [Also in Group XXXIX] An interrupter type motor, particularly for automatic telephone selector ..system,4, has circuit switching devices controlled both by the rotor and electromagnetically so that it makes only one step for each impulse supplied whatever its duration. In the form shown, the rotor R is mounted on a spindle 13 which passes through axial holes in the cores of the stator electromagnets M, N whose single poles 10, 11 are disposed at right angles around the rotor. A common flux returning pole 12 is secured to the magnetic supporting yoke 9. The rotor is shaped to produce rotation in one direction only, this rotation taking place in 90 degrees steps from pole to pole, the drive being taken from a gear 4. The other end of the shaft carries a pair of cams 27, 28 controlling spring contacts CMS, CNS respectively. In addition, electromagnets CM, CN are provided to operate or retain operated each switch and also a pair of switches cm, en which are not controlled by the cams but are operated by the received impulse to ensure that only one field magnet is energized by each impulse. The outer blades 31, 32, 33, 34 are faced with soft iron strips for attraction by the electromagnets CM, CN. In circuit diagram, Fig. 7, the cams 27, 28 are represented by a single cam K. Contact al is the " break contact of an impulse receiving relay and c1, c2, c3 are contacts of a dialling relay operated subsequently to a1, but before impulses are received. Contact sd1 is closed to secure automatic homing of the motor under the influence of the cam-operated switches only. The energizing impulses pass through contacts cn, CMS to energize the field magnet M and electromagnet CM which retains CMS closed and opens cm while the rotor turns through 90 degrees and closes contact CNS which, however, has no effect while cm is retained open by . electromagnet CM. On termination of the impulse contacts cm and CMS are released so that the next impulse energizes the field magnet N and produces a further 90 degrees movement. In a modified form the separately controlled switches cm, cn and CMS, CNS are united into simple changeover switches, the cam being turned through 90 degrees and each field pole has two windings. In a further modification the contacts cm, cn are omitted altogether and the cam is turned through 45 degrees with respect to the rotor.
