Abstract: 543,513. Electric indicating systems, BRITISH TABULATING MACHINE CO., Ltd. June 28, 1940, No. 11034. Convention date, June 30, 1939. [Class 40 (i)] [Also in' Groups XL and XX] In record controlled statistical and like machines, the final characters are indicated on the screens of cathode-ray tubes, the deflecting electrodes or coils of which are controlled by two-part pattern-component emitters corresponding to the several characters. In one arrangement the emitters are photo-electric ones, and in another arrangement, the emitters comprise sets of rotating distributers connected to a tapped potential divider. The characters formed on the screens of the cathode-ray tubes may be recorded by a film camera. The general arrangement and construction of the machine shown is otherwise substantially as usual in " Hollerith " calculating machines.

Abstract: 558,239. Moulding walls and floors in situ. SHINGLETON, L. Aug. 7, 1942, Nos. 11082 and 12414. [Class 20 (ii)] A method of casting in situ concrete walls and floors comprises the use of thin pre-cast permanent concrete slabs not self-supporting, and tubular scaffolding for adjustably supporting the slabs in position by means of removable plates, supporting or positioning the corners of slabs which abut. The pre-cast slabs 20 are about 1.5 inches in thickness and are provided with apertures 22 at the corners adapted to be engaged by studs 30 on plates 34, these plates being either integral with or adjustably attached to struts 35 adapted to be adjustably clamped to scaffold members 23 positioned on one or both sides of the wall. The studs may simply engage the holes in the slabs to position them, and the slabs are spaced apart by collared spacers 31 with spiked ends 33, or the studs may be screwed internally or externally to engage with the screwed ends of collared spacer rods or tubes respectively, the collars on the spacers bearing against the inner faces of the slabs. After removal of the plates and studs, the spacers remain in the wall and the holes in the slabs are filled with cement. The edges of the slabs may be bevelled off so that concrete may enter and bind them together, and the slabs are reinforced with metal. The struts for the supporting plates may be supported by right- and left-hand screw adjusters 26 from the scaffold 23, and when the scaffold is disposed on one side of the wall only, plates 42 without struts but with positioning studs are used on the opposite side coacting with the screwed ends of the rods or tubular spacers. For corners of walls, small auxiliary slabs 51, Fig. 14, are used supported by plates 42 and held in position by hooked ties 50 engaging over the wall spacers. For floors, Fig. 11, the slabs are supported at their corners by struts 35, and hooks 48 formed with the slabs and projecting therefrom are adapted to engage over the floor reinforcing-bars 49 ; the reinforcement of the slabs is caused to project at the ends thereof and is bent over the flanges of the metal supporting beams so as to bind the slabs to the beams. Window frames are formed by concrete members 54, Fig. 15, disposed between the slabs, which are modified in size accordingly.
