Title: Governor mechanism for phonographs and other machines
IPC: G11B17/02
Filed: 1919-10-22
Abstract: 154,411. Wade, H., (Mills, H. S.). Oct. 22,1919. Actuated by speed regulators; acting on flat sides of wheels, drums and discs.-Governor mechanism for phonographs and other machines comprises a continuously-rotating driven member provided with means for exerting oscillatory impulses on a balance wheel, the said means reacting on the driven member to control its speed. Fig. 2 shows the governor in vertical section applied to a phonograph, and Figs. 3 and 5 show details. A cam comprising a circular wavy band 35 secured to the turn-table 20 by lugs 21 and vibration-absorbing washers 36 is engaged bv a forked member 42, which is mounted on a spindle 38 and is connected by a coiled spring 45 to the hub of a balance wheel 39. The forked member has spring arms 43 of a length equal to half the wave length of the, cam surface, and carrying at their outer ends pins 44 engaging the upper and lower surfaces of the cam. As the turntable rotates, an oscillatory movement is transmitted to the balance wheel 39 by the cam 35, and when the speed exceeds the normal the balance wheel offers a resistance with causes the pads 44 to retard the cam and to reduce the speed to normal. The normal speed is adjusted by turning a snail cam 50 which bears on a pivoted arm 49 and varies the tension of a spring 48 attached to the balance wheel 39. Felt bushing is interposed between the fixed spindle 38 and the hubs of the balance wheel 39 and forked member 42.

Abstract: 795,285. Ice-cream servers. EKCO PRODUCTS CO. Sept. 12, 1955 [Sept. 17, 1954], No. 26001/55. Class 87(2). The scraper 21 of an ice-cream server is rotated around the inside of the scoop by pulling a lever 15 until it abuts against the handle 13. The other end of the lever has a racked quadrant 37 which rotates a pinion keyed to the shaft of the scraper. A locking member 17 is also keyed to the shaft, and has a recessed part (see Fig. 7, not shown) to allow it to be moved to the right as shown in Fig. 2 over the teeth of the pinion. The quadrant has a large tooth 138 to ensure that it does not move off the pinion. The lever is returned by a spring 16. To dismantle the parts for cleaning, the lower part of the handle 13 is unscrewed, to allow the quadrant to move off the pinion, when the lever 15 is moved inwardly, thus allowing the scraper element to be removed from the scoop as in this position the recessed part of the locking element may be moved over the teeth of the pinion.

Abstract: 699,159. Making reinforced pipes. BADISCHE ANILIN- & SODA-FABRIC. Nov. 8, 1951 [Nov. 10, 1950; Nov. 11, 1950], No. 26149/51. Classes 83 (ii) and 83 (iv). [Also in Group XXVIII] Welding.-In a method of welding branch pipes to the walls of pressure vessels, &c., which are reinforced by wound metal bands, adjacent windings are joined together as by welding, dowelling, &c., in the region of the branch. In one example, windings a, Fig. 1, on a pressure vessel wall d are tack welded during winding as at c to the windings immediately below in a ring of welds surrounding the position at which a hole for the branch pipe b is to be cut. In another example adjacent windings a, Fig. 2, are welded together as at c<SP>1</SP> in the region of the branch, the windings being bevelled or made narrower in this region to leave a gap for welding metal. In another example applied to pressure vessels already wound, the windings a, Fig. 4, are interconnected by dowel pins o inserted through holes drilled through the layers. The pins may be carried by an external cover member (not shown). In a further example the branch b, Fig. 5, is surrounded by a sleeve g which may comprise separate rings welded together, the sleeve being retained on the pipe b by a screwed sleeve k or by welding. The windings a are welded together and to the sleeve g as at p. In another example, the windings are welded together and to the pipe b, Fig. 6, by a weld as at g<SP>1</SP>, but in a modification of this example the windings are not welded to the pipe b. In all cases the strength of the joint may be increased by adding further layers of winding in the region of the branch and by welding on a strengthening disc. The joints may be heat-treated as by local heating to red heat by a flame or electrical induction heating.

Abstract: 1507843 Transferring liquids through pipelines ANIC SpA 19 June 1975 [1 July 1974] 26203/75 Heading F2N A system for conveying a plurality of pure liquids along a single tube having an intermediate inlet/outlet port, from and to one of a number of pipes, each of which carries one of the pure liquids, has a conduit attached to either end of the tube for communicating with any one or the same pipe of the number of pipes, and a system for separating the pure liquids to be conveyed by means of spheres and an inert liquid miscible with said pure liquids between adjacent spheres. In the embodiment described conduits 10, 11 and tube 23 are filled with liquid L<SP>1</SP> which has been conveyed through pipe 1. It is desired to convey liquid L<SP>5</SP> between pipe 5 and inlet/outlet 20. Inert liquid, e.g. water, is pumped from container 14 via pump 13 and conduit 10 forcing liquid L<SP>1</SP> into pipe 1, and when the inert liquid reaches pump 12 or device 15 a sphere, "pig" 17, is released into said tube. A known volume of inert liquid is pumped in and a second "pig" 18 released. A second volume of inert liquid is released and a third "pig" 19 released to separate the inert liquid and liquid L<SP>5</SP> which is now pumped from pipe 5 such that tube 23 is filled over most of its length by liquid L<SP>5</SP> and spheres 17, 18 have reached collecting vessel 16. Outlet 20 is thus in communication with liquid L<SP>5</SP> in the tube 23. Liquid L<SP>5</SP> may then be pumped direct from pipe 5 via conduit 10 to outlet 20. For feeding liquid L<SP>5</SP> to pipe 5 from inlet 20, conduit 11 is connected to a branch connection of pipe 5 and sphere 19 with inert "plug" liquid collected in vessel 16 and appropriate valves shut such that liquid 5 passes from inlet 20 via tube 23 and conduit 11 to pipe 5.

Title: Improvements in optical-projection apparatus
IPC: G03B21/06
Filed: 1921-10-04
Abstract: 195,660. Graves, A. Oct. 4, 1921. Optical-projection apparatus for episcopic projection utilizing a light source in conjunction with a reflector, has the reflectors so constructed that the illuminated area at the object is of such shape that overlap wastage of light is reduced. In addition to a large curved reflector a small hemispherical bowl reflector is fitted near the source of light and between it and the object. Further, the projection lens is not corrected for actinic rays, thereby enabling flatter curvatures to be used for the surfaces of the component and permitting an increase in diameter and aperture. The spacing of the components of the lens is such that the back focal length is considerably shortened. The surface of the large reflector b is built up of a number of merging components, one portion along a diameter being parabolic and the portion at right angles being a curve of constant eccentricity other than a parabola. The intermediate portions gradually merge from one curve to the other. This form enables the light to be substantially of the same shape as the object c, Fig. 5. In conjunction with such a reflector a small hemispherical bowl reflector j, Fig. 8, is used. The components of the projection lens, Fig. 9, are mounted in separate sleeves so that the distance between them may be adjusted by rotation. For projection in daylight the lens e may be situated at one end of a divergent tunnel having a transparent screen at the other end, or the screen d, Fig. 14 may be situated above the object c and two plane mirrors o, p employed enclosed in a cabinet. A series of objects may be carried on a number of circular platforms rotated automatically about a vertical axis, arrangements being provided to raise these platforms successively into the position for projection purposes.

Abstract: 375,625. Feeding webs. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Morton, E. R. ; 81, Horatio Street, New York, U.S.A.) Sept. 19, 1931, No. 26261. Convention date, Sept. 27, 1930. [Class 100 (i).] In a device for intermittently feeding a strip such as a kinematograph film, the movement is obtained from a member which has a circular or cam-shaped periphery provided with sprocket teeth &,c. for engaging the strip and which is carried eccentrically on a shaft having a rolling movement about a fixed axis. In the construction described, sprocket wheels 7, Fig. 2, are eccentrically mounted on a shaft 5 of a gear wheel 2 which is driven round the inner toothed periphery of a fixed ring 1 by a rotary shaft 4 and bracket 3. Preferably the peripheries of the gear wheel 2 and sprockets 7 coincide at one point so as to provide for engagement and disengagement between the sprockets and the film when the feeding movement of the sprocket is zero. In order that the film engaging and releasing positions of the device may be uniform, the pitch circle diameter of the toothed ring 1 is an integral multiple of that of the gear wheel 2, or differences may be compensated by imparting a suitable rotation to the ring 1. Preferably the parts are balanced as by a weight 8, and cut out recess 10, or a number of the film-engaging devices may be arranged in balanced formation about the shaft 4. A guide for the strip may be provided to define the points at which the strip will be engaged and disengaged by the impeller. In the modification shown in Fig. 7, the film-engaging member 38 is smaller than the gear wheel 37 and is shaped to provide a straight film track 39. The guide in this case may be dispensed with.
