Abstract: 886,974. Measurement of fluid flow by radio-activity. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 28, 1960 [July 28, 1959], No. 25815/59. Class 40(3). The volume rate of flow of a fluid in a system is measured in terms of the axial displacement of a radioactive float in a tube connected to the system so as to maintain constant pressure across the orifice formed between the float and the tube by at least one co-operating detector located near the tube. A tube 1 containing a float 2 is surrounded by a block 3 of radiation absorbing metal in which are holes 4 at different points along the tube, each hole being radial to the tube and leading to a. cavity 5 in which is a radiation-sensitive detector. The outputs of the detectors may be supplied to indicators such as lamps, be utilized for controlling the flow, and/or be supplied to a bridge circuit whose out of balance current is indicative of flow. The block may be movable to extend measurement over the range of possible movement of the float and movement of the block to the position giving maximum output from one detector may indicate the flow.

Abstract: 238,100. Assmus, F., and Kloss, S. Nov. 3, 1924. Spray carburettors.-The mixture of fuel and air is subjected to centrifugal action in a rotating drum, having its wall perforated, and preferably divided internally by a longitudinal perforated partition. The casing consists of two castings 1, 2, of which 1 contains the rotating drum 38 and 2 the fuel spraying means. Fuel from a float chamber is fed through a passage 16 to channels 47, 48 of which 48 leads to the edge of the throttle valve 46 and serves as a slow running device. Channel 47 leads to the sprayer 22 controlled by needle valve 24 and the fuel therefrom is mixed in the chamber 34 with air admitted through passages 25 controlled by a disc valve 26. From chamber 34 the mixture passes propellers 33, 40 on its way to the drum which, together with the propellers, is rotated by a main air stream entering through sieve 27 and passing ribs 20 and through controllable ports 36 and acting upon helical blades 42, 43 on the perforated wall. Interiorly the drum is preferably divided by a perforated partition 39. Fuel is drawn into the float chamber by suction transmitted through a pipe 17 the float carrying two valves, the upper controlling the suction and the lower the flow to the sprayer.

Title: Improvements in overrunning clutches
IPC: F16D41/00
Filed: 1930-09-03
Abstract: 355,522. Free-wheel clutches. McGRATH, W. L., of Eclipse Machine Co., Elmira, New York, U.S.A. Sept. 3, 1930, No. 26334. Convention date, Sept. 10, 1929. [Class 80 (ii).] A free-wheel clutch, shown applied to a starter drive for an internal-combustion engine, comprises an intermediate toothed member 24 rotatably and eccentrically mounted on the driven pinion 21, and engaging an internally-toothed driving ring 15. The driving faces of the teeth are cut away radially permitting sufficient backlash to give a solid drive to the pinion 21 in the forward direction, arrow a, Fig. 2, through the abutting flat tops 26 of the teeth, whereas when the pinion 21 overruns, arrow b, Fig. 3, normal tooth faces contact and the intermediate member planetates idly. The ring 15 is attached to a flanged sleeve 14 splined to the armature shaft 10 of the starter motor and the pinion 21 is constrained to move axially with the sleeve to engage the engine flywheel 33 by an endplate 31 and a flanged bearing sleeve 22 which is a press fit on the pinion. Axial movement is effected manually by a loose collar 27 pressed against a split end ring 28 on the sleeve by a spring 30. In a modification the eccentric is riveted to the driving flange 14 and the internally toothed ring is associated with the pinion. Both gearing elements are laminated, the ring laminations being drivingly carried in a flanged drum splined on the teeth of the pinion and located axially on the flange by a split end-ring. The pinion is axially located by an inner annulus retained by the flanged drum and engaging a circumferential groove in the pinion. In this form overrunning causes simple spur gearing action, the intermediate member rotating freely on the eccentric. The clutch parts may be made from stampings and punchings.

Title: Manufacture of small spherical particles

Abstract: 1,134,535. Granulating. SOUTHWEST RESEARCH INSTITUTE. 7 June, 1967 [20 June, 1966], No. 26398/67. Heading B5A. Small spherical hardened particles are produced by extruding a stream of liquid material, e.g. molten wax, within a confined stream of carrier liquid, e.g. hot water which is chemically non-reactive and physically immiscible with the material, and which flows at a speed greater than the rate of extrusion of the said material causing it to break up into spherical particles which are then hardened, e.g. by cooling the carrier liquid. Apparatus providing hardened capsules in which a filler material is encased within a shell of film material comprises a conduit 10 with coaxial inner and outer tubes 11, 12 through which hot melts of filler material and film forming material respectively are fed from receptacles 15 and 14. On leaving the ends of the tubes the two extruded streams are met by a hot stream of carrier liquid supplied by conduit 20 to the conduit 10 and which, passing through a convergent part 10c, flows at a greater speed than the material streams and breaks them up into capsules which are carried through a section 10b to a vessel 24. The capsules float in the vessel and pass to a screen conveyer 26 and are received in a container 27<SP>1</SP>, carrier liquid is returned to the conduit 20 for recirculation. A heat exchanger 19 cools the carrier liquid and a heat exchanger 23 heats it. In a modified apparatus, instead of hardening the capsules by cooling, the capsules are conveyed by the liquid carrier to a vessel containing a liquid hardening medium immiscible with the carrier liquid, and the two liquids stratify in the vessel so that the capsules fall through the carrier liquid and pass to an outlet from which they are received by a conveyer. In this embodiment each capsule may comprise a filler of hexane within a shell of aqueous sodium alginate; the carrier liquid may be naphtha and the hardening medium aqueous calcium chloride.
