Sheet-feeding arrangements.-Relates to condensed-billing arrangements in which the original and duplicate sheets are fed at different rates. According to the invention, a. differential-feed device is provided which lightly presses the original and duplicate sheets against the platen, thus enabling all the work-sheets to be of uniform width. In the form described, the device comprises two sets of rolls 7, 8, Fig. 1, connected by endless belts 47. Fig. 5, which bear against the platen, the rolls being caused by gearing to rotate with the platen, but at a different speed. The duplicate work-sheet is held against the platen by an independent set of feed-rolls 12 on a shaft 13 carried by arms 14 pivoted on a shaft 15. The rolls are pressed against the platen by springs 20, and the shaft 15 is jointed at one end to the platen frame and is releasably held at the other by a cranked pin 59 and a catch 17. The rolls 7, 8 are fast on shafts 29, 30 mounted in yokes 28, and are movable to and from the platen by a cam shaft 23 which has flattened portions co-operating with bearings 26 and is rotated by means of a link 21 and a finger-piece 9.

[Class 79 (iii).] Means for locking the steering wheel of a motor vehicle to prevent unauthorized use, comprises a pair of oppositely facing cupped members A, B, one with peripheral holes J being secured to the steering wheel or its shaft and normally rotatable within the other which is secured to the steering pillar or, in the absence thereof, to an adjustable bracket carried by the dash &c. Looking is effected by inserting a key-carrying member U, Fig. 3, into a keyhole-shaped slot K in a lug or boss D on the cupped member B, the end of the member U entering one of the holes J in the wall of the inner cupped member A, at the same time making contact with an electric terminal E bringing an alarm device into operation. The key U<1>, which is removable, controls rotation within the member U of a sleeve carrying a lug Y so that withdrawal of the member U may be prevented by turning the lug Y within a circular chamber X beyond the keyhole slot K. The cupped member B is secured by nuts R<1> on bolts R fixed in a flange P on a divided sleeve O clamped on the steering pillar W by bolts N or, if the member B is carried by a bracket, the inner cupped member A is secured to the steering shaft by such means. As shown, the member A is secured to a disc or plate C by screws M which traverse radial bores S wherein grub screws L fixing the disc C to the steering wheel hub T are located, access to the grub screws being thereby prevented. The attachment elements being enclosed, access thereto is prevented when the device is locked, removal of the nuts R<1> being ineffectual as the bolts R are fixed in the flange P.

Abstract: 451,941. Casting in situ; conduits in structures. WARBURTON, R. E. L., 42, Rutland Gate, South Kensington, London. Feb. 11, 1935, No. 4314. [Class 20 (ii)] A tubular former used in casting hollow concrete structures consists of a plurality of spirally-wound or lap-wound layers of flexible strip material, one or more of the layers being coated or impregnated with a waterproofing medium. A number of layers 1, 2, 3 of strip material may be successively wound in spiral form over a mandrel as shown in Fig. 1, and an adhesive, such as bitumen, is applied between the layers 2, 3 during the winding operation. An outer coating of bitumen, synthetic resin varnish, cellulose, or wax is applied to the outside of the layer 3. A similar former may be produced by winding a sheet of cardboard or the like on a mandrel to form a lap-wound tube, the adhesive being applied to the inner side of the sheet. The strip material may consist of paper, cardboard, or chip-board. A concrete floor may be formed by casting a layer 7 of concrete on to shuttering 5 as shown in Fig. 3, positioning tubular forms 9 on this layer by means of spacers 8, and applying a second layer 10 of concrete so as to embed the formers and spacers. In forming a hollow wall, the tubular formers are supported within the shuttering for the lower section of the wall before the concrete is cast by means of spacing and supporting members independent of the shuttering. Any of the forms may serve as a conduit for cables, wires or pipes for various devices within the building. In a concrete road, the formers may form conduits for electricity supply or drainage systems.
