Title: Improvements in or relating to the manufacture of reinforced concrete floors
IPC: E04B5/23
Filed: 1932-10-20
Abstract: 395,911. Concrete floors ; ceilings. NOVICIC, V., 37, Krunska, Belgrade. Oct. 20, 1932, No. 29404. Convention date, Feb. 1. [Classes 20 (ii) and 20 (iv).] A reinforced-concrete floor is built up of main reinforced-concrete beams provided with double iron reinforcements connected by loop members, the beams being provided with two or more series of laterally extending holes the upper holes serving for the passage of anchor stirrups and for the passage of the concrete of the slab, while the lower holes serve for the passage of iron joists and iron concrete ties. Fig. 1 is a vertical longitudinal section of such a floor, while Fig. 4 is a cross sectional view taken through an upper hole of one beam and through a lower hole of the next beam. The beams are provided with lateral holes 5, 6, Fig. 1, and are fitted with two layers 7, 8, Fig. 4, of iron work which are embraced by bent rods 9. In the case of deep ribbed floors the upper end of iron work 11 is allowed to project above the beams when every other loop 12 of the bent rods 9 also projects from the beam. Iron works 3 of the slab are arranged above the beams and anchor stirrups 14 are provided through the upper holes of each beam to embrace the iron works 3. The stirrups 14 may be so long as to extend continuously over the slab when they serve both as stirrups and as the main iron work of the slab. The lower surface of the slab may be either flat or shaped obliquely, the temporary support structure being shaped accordingly. This structure is supported by the main beams through the lower holes of which are drawn members 16, Fig. 4, to which beams 17 are fastened. Diagonal joists 18 are disposed over the beams 17 and wedges are interposed to facilitate removal of the temporary structure, which is effected by first removing the members 17 whereupon the whole of this structure becomes free. Posts 20 are set in position within notches in the joists 18 to serve as supports for iron sheets 19, 25. After the concrete has been poured into position the lower holes 6 of the beam remain free from concrete except in the region of the stiffening parts such as 22, Fig. 1, where the holes 6 are also filled with concrete. For supporting the ceiling structure galvanized iron wires 24, Fig. 4, are passed through the lower holes 6.

Title: Apparatus for indicating the mean speed of a vehicle
IPC: G01P11/00
Filed: 1948-11-12
Abstract: 674,227. Speedometers. GALAND, M. Nov. 12, 1948 [May 24, 1948], No. 29414/48. Class 106 (iii). Apparatus, for indicating the mean speed of a vehicle, comprising registers having logarithmic cams which are rotated respectively in proportion to the travelling time and to the distance travelled, the movement of the cams being transmitted to a comparator by means of which the mean speed may be ascertained is characterised in that each register comprises a number of logarithmic cams arranged in stages and each cam directly drives a toothed sector which meshes with a pinion on a common shaft connected with the comparator. Each logarithmic cam, Fig. 2, is formed by an aperture 3 in a disc 9, the surfaces 3a and 3b of which aperture co-operate with a roller 11 on a toothed sector 6 which meshes with a pinion 7 on a shaft 8. A register comprising three stages is shown in Fig. 3, reduction gearing 12 and 13 being between the first and second and second and third stages respectively. The arrangement is such that each sector in turn drives the shaft 8 as it is moved by its associated cam 3 against the pressure of a spring 5, Fig. 2. No movement is imparted to a sector as its roller 11 rides along the surface 3a of the associated cam the length of which corresponds to the time during which the shaft 8 is driven by preceding cam or cams. The length 3a of the first cam, not shown, is therefore zero. As each sector completes its movement it is locked by a spring- pressed pawl 14, Fig. 2. When all the discs 9 reach their final positions notches 19 therein are aligned with rollers 17 carried by arms 18 mounted on a shaft 16. The arms 18 are then moved by a spring so that the rollers 17 enter the notches 19 and so lock the discs 9. Upon this movement the pawls 14 are rocked to free the sectors 6. The comparator which is connected to the shafts 8 of the two registers corresponding to " time " and " distance " respectively may be in the form of a differential gear, Fig. 5 (not shown), or two superposed discs, one bearing two logarithmic scales and the other a window, Fig. 6 (not shown).
