Abstract: 789,933. Conduits in floors; floor units. ROBERTSON THAIN Ltd. (Robertson Co., H. H.). April 27, 1956, No. 13060/56. Classes 20(2), 20(4) and 87(1) A floor is formed from a plurality of multi-cellular sheet metal units assembled side-by-side and end-to-end upon a supporting framework. Each unit comprises an upper corrugated sheet 12, Fig. 1. and a lower corrugated sheet 14, united together such as by welding, to form a unit having a series of closely spaced parallel cells 16 which in the assembled floor form a plurality of continuous ducts or conduits through which electrical wiring may pass. The ends of sheet 12 are spaced from each end of the lower sheet 14, and marginal lip portions 20, 22, on the sides of sheet 12 allow adjacent units to be connected sideby-side. The leading end 24 of the corrugated sheet 14 has upwardly offset upper and lower wall portions 28, 30 of the corrugations to engage over the corresponding straight wall portions at the trailing end 26 of an adjacent unit. The trailing end 26 has its lower sheet 14 provided with outwardly offset side wall portions 32, 34 of the corrugations to embrace and overlap the corresponding side wall portions at the leading end of the adjacent unit. A transverse rib 46 is provided in the bottom wall of the trailing end 26 to enable cables to be pulled through the units without fouling the raw edge at the leading end of each unit. Openings 38 in the bottom wall of the leading end 24 enable the assembled units to be welded together and to a girder on which they rest. Finally the openings between adjacent sheets 12 are closed by corrugated cover plates which extend across the width of the unit and are welded or otherwise secured thereto. In a modification the rib 46 is replaced by a separate half-round sheet metal member welded to the bottom wall of the trailing end 26. In an alternative form, Fig. 7, the lip portions for connecting adjacent units in side-by-side relation are formed on the lower sheet 15. These lip portions 21. 23 have their leading and trailing ends provided with offset wall portions similar to those of the main part of the corrugation. In another form, Fig. 11, each floor unit has an upper flat sheet 72 welded to a lower corrugated sheet 74, the leading and trailing ends of the latter having offset portions 80, 82 and 84, 86, similar to the lower sheet 14, Fig. 1. The upper sheet 72, has marginal lip portions 88. 90, to enable the units to be joined side-by-side. The gaps between sheets 72 when the. units have been assembled are closed by flat cover members.

Abstract: 1496202 Watches SOC SUISSE POUR L'INDUSTRIE HORLOGERE (SSIH) MANAGEMENT SERVICES SA 7 April 1975 [8 April 1974] 14075/75 Heading G3T In a watch setting mechanism comprising a pullout piece 2 which pivots on a pin 6 when a stem 1 is moved axially, a single V-shaped part 3 has a first resilient arm 11 functioning as check-spring, return bar and return bar spring, and a second resilient arm 14 engaging the pin 6 and over-lying the pull-out piece to act as a fulcrum spring. The part 3 is attached to the movement near its apex 12 by a screw 13 in a manner permitting slight rotation. The enlarged end 10 of arm 11 carries a setting wheel 18 and a pin 16 which causes grooved pinion 17 to slide on the stem and thus remain in mesh with the wheel 18. The mechansim is described in relation to an electric watch and is shown in a neutral position. If the stem is pushed in, a beak 8 of the pullout piece touches a contact 20 to cut-out a number of frequency divider stages and speed up the motor of the watch for hand setting. Pulling out the stem from the neutral position causes a further beak 7 of the pull-out piece, in co-operation with the edge 9 of arm 11, to bring the wheel 18 into mesh with wheel 19 coupled to the hour hand Fig. 2 (not shown). The outer edge of beak 8 then abuts a pin 15 on the arm 14 to lock the pull-out piece. A clutch (not shown) permits setting of the hour hand only. A further outward pull on the stem deflects the arm 14 allowing the pull-out piece to engage a fixed conical stud 21 whereby the piece 2 is laterally deflected and stud 5 thereon moved out of groove 4 in the stem. The stem is thus freed for removal. Reinsertion is facilitated by a tapered portion 22 on the stem to raise the stud 5.
