Title: Process for the manufacture of reinforced concrete pipes and the like hollow bodies
IPC: B28B21/58
Filed: 1935-10-17
Abstract: 446,625. Reinforced-concrete pipes. OVERVAD, M., 9, Hadsherredsvej, Aarhus, Denmark. Oct. 17, 1935, No. 28757. [Class 99 (ii)] [See also Group V] In a process for centrifugally moulding concrete pipes and like hollow bodies having an internal metal pipe reinforcement, an outer layer of concrete is first moulded in a rotating mould, a metal pipe slit longitudinally in one or more places is then applied to the interior, and finally an inner layer of concrete is moulded centrifugally, whereby the concrete, or a sealing cement applied near the slits, passes through the slits during the final moulding operation, so as to ensure the solidity of the outer layer. In the form shown in Fig. 1, the pipe 3 is slit longitudinally in one place, and the edges overlap at 4, 5. In other forms, one or more open slits may be employed. The open slits may be covered by a curved strip fitting against the inner surface of the pipe 3, and secured thereto on one side only of the slit. The metal pipe may be formed of two or more parts overlapping at the edges. The slit metal pipe may be resilient, so that it can be compressed to a smaller diameter to facilitate its insertion into the outer moulded layer. The inner edge 5 of the pipe may be provided with a flange 9, Fig. 6, to form a recess to receive sealing cement 10. In another form, Fig. 7, the edge 5 is bent to provide a hollow rib 11 which is filled with sealing material before the pipe is inserted in the mould, openings 12 being provided to enable concrete to penetrate during the subsequent centrifugal moulding. Alternatively, a rib 13, Fig. 8, may be attached to or formed in the pipe so as to prevent dispersion, during moulding, of the sealing material applied behind the flange 9.

Filed: 1933-10-18
Abstract: 408,163. Autographic recorders. HARTWIEG, W., 64, Birkbuschstrasse, Steglitz, Berlin. Oct. 18, 1933, No. 28773. [Class 106 (i).] In an autographic recorder in which the two or more paper strips are straightened by bonding them over the edge of a bar at their folded or perforated boundaries, the straightening is effected during a discontinuous feed movement by the rubbing of one or more feed rollers on the section to be straightened. As shown, one or more folded and perforated paper webs 1, Fig. 4, are drawn over a writing plate 4 by manually rotated feed rollers 5 co-operating with a counter-roller (not shown). As a fold in the web reaches the sharpened leading-edge of the writing plate, the web is clamped thereagainst by the hooked upper end of an arm 13 pivoted to a lever 17. This is effected by a cam 22 on the feed shaft that rocks the lever 17 counterclockwise and thus stresses a spring 12 connected to the arm 13 to urge the latter in counterclockwise direction. The feed rollers are provided with recesses 6 so positioned as to arrest the feed just prior to the clamping of the web. The central roller, Fig. 3, however, is provided with an arched part 11 that may be formed integral therewith but is preferably pivoted thereto and pressed outwardly by a spring 10. This arched part rubs against the clamped web and straightens it. The web is maintained in clamped condition during the straightening by means of a detent 26. At the beginning of an operation a knob 29 is pressed in to release the operating handle and trip the detent. The hook-shaped part of the clamping arm may be dispensed with, in which event the arm is sloped to press the web against the underside of the writing plate.
