Title: Rotary sand papering tool
IPC: B24D9/00
Filed: 1946-03-27
Abstract: 614,437. Rotary sand-papering tools. BONKOWSKI, T. L. March 27, 1946, No. 9523. [Class 60] A rotary sand-papering tool of the type comprising a cylindrical drum provided on its circumference with a plurality of radial brushes over which abrasive sheets extend which are withdrawn from a common supply reel within said drum, is characterized in that the inner face of the supporting plate of the drum is provided with indexing means arranged concentrically with respect to a spindle fixed to said supporting plate and on which said abrasive sheet supply reel is mounted, said indexing means co-operating with complementary indexing means on the reel to hold the latter from rotation on the spindle when the reel is axially moved toward the supporting plate and the front plate is secured in position. An end-plate 12 has a hub 13 for receiving a driving shaft, a central spindle 14, a wall 19 and housings 15 for receiving the backs 33A of brushes 33 or other backing elements for the free ends of the abrasive strips 30 which issue through slots 34 or 35 (according to the direction of rotation) in the wall 19.. The drum may be octagonal instead of circular. A coverplate 17 is retained by a wing-nut 39 screwed on the end 14A of the spindle 14 and engaging ring 27A of a spider 27. The strips are wrapped around a core 20 mounted on the spindle 14 (which may be press-fitted into the plate 12 when the latter is of relatively soft material, e.g. die-cast) and comprises an outer tube 21A, slotted for the strips, the inner ends of which are secured by staples &c., and an inner tube 21B; rods 23 connecting the tubes present at their lower ends flanges 23A which co-operate with grooves 29 in the end-plate 12 to restrain the core 20 against rotation relative to the drum; the upper part of the core 20 projects through the cover plate 17, so that, after slackening the nut 29, the core can be lifted and indexed around to feed fresh portions of the strips. In a modification, Fig. 5, the core comprises a sleeve 18a to which the inner ends of the strips are secured and on which the strips are wound, and having slots 19a, 20a engaged by tongues 24B, 25B on the core member 21a proper. The sleeve 18a may be a paper tube, or may be made of plastic, fibre or metal; its cost being small, it can be discarded when the sand-paper is used up, and replaced by a new charged sleeve. Each strip, Fig. 9, may have staggered slots so that according to where it is cut across its length a number of tongues are produced.

Title: Liquid fuel feeding devices for power plants or engines
IPC: F02M69/00
Filed: 1946-03-28
Abstract: 652,854. Spray-carburetters. BENDIX AVIATION CORPORATION. March 28, 1946, No. 9625. Convention date, April 2, 1945. [Classes 7(iii) and 7(vi)] In a liquid fuel feeding system comprising a centrifugal governor controlling a fuel flow valve, a whirling motion is imparted to the fuel by the governor and a passage vents fuel vapour collecting at the centre of the whirling fuel. In Fig. 1 a vane pump 14 supplies fuel under pressure to a chamber 19 from which it flows through a valve 28, Fig. 3 controlled by a centrifugal governor 36, to an unmetered fuel chamber 72 leading to a metering orifice 91 controlled according to air charging pressure and exhaust back-pressure by a needle valve 90 attached to capsules 93, 97. The governor 36, attached to a hub 39 driven by a cup 42 from the pump rotor 14, imparts a whirling motion to the fuel and vapour escapes through passages 107 in an abutment member 26 of the pump cam-pin 15, and through passages 108 and 110 to a chamber 111 having a float controlled valve 115 through which the vapour escapes to the fuel tank or intake pipe. Fuel escaping through the vapour escapepassages supports the float 112 and the excess returns through passage 117 and orifice 118 to the suction side of the pump. The fuel pressure in chamber 19 is maintained at a fixed value above that in the chamber 72 by means of a spring-pressed byepass valve 62 controlled by a diaphragm 68 connected by a passage 71 to the chamber 72. A portion of the fuel byepasses the metering orifice 91 through an orifice 99 and a valve 100 controlled by a temperature responsive device, the pressure drop across orifice 99 being applied to a diaphragm connected to a cable 54 to the valve 28, the force produced balancing that of the centrifugal governor. The fuel flow is thus controlled according to engine speed and corrected for variations in temperature, charging pressure and exhaust back pressure. An idling cut-off valve 62 cuts off the fuel when the engine stops and also disconnects the pipe 71 from the chamber 72 to allow the byepass valve 62 to open easily and avoid excessive pressure in the chamber 19. Specification 652,853 is referred to.
