Title: Apparatus for finishing glass or like articles on a grinding wheel
IPC: B24B37/30
Filed: 1925-07-17
Abstract: 249,461. Rostaing, P. March 23, 1925, [Convention date]. Disc apparatus; gauges; guides and rests; spindle mountings.-Apparatus for finishing the end edges of glass, crystal, &c. articles of truncated conical, cylindrical, or other form by means of the flat surface of a grinding-disc, comprises a table surrounding the disc and adjustable to compensate for wear of the disc, the articles being mounted in carriers which are movable on guides secured to the table, the underside of the articles being presented to the flat upper surface of the disc. The disc 2 is carried by a rotating member 3 mounted on ball bearings 21, 22 on a spindle 16 and driven by a pulley 23, and a table 13, provided with openings 5, is arranged above the wheel, the table forming a guiding-surface 4 parallel to the grinding-surface. Frames 6, in which are mounted the articles to be ground, are placed in the openings 5 and are moved therein by handles 9 to carry the articles across the grinding-surface; flanges 8 on the frame contact with the surface 4 when the articles are to size, and prevent further grinding. The table 13 is secured to a member 14, screwed to engage the upper end of the spindle 16 and may be locked by a bolt 18; rotation of the table and member 14 adjusts the height of the table to compensate for wear of the grinding-surface. The bearings 21, 22 are protected by a leather washer 24, and the table 13 has passages 25 to allow of removal of grit &c. The frames 6 may comprise a drum 7, Fig. 4, having a rib 29 or 29<1>, the article holder 11 being placed in the drum and having openings 10 in which the articles 1 are placed. The articles are pressed upwards, when grinding the larger end, by rubber discs 33 on spring- pressed spindles 36, or by springs 37. A member 30 clamped by a cover 27 holds down the member 11. When the small ends of the articles are to be ground, the members 11 and 30 are reversed, the articles being held down by the member 30. In an alternative form of holder, the member 11 is held in position by bolts having flattened heads which are passed through slots in the member and in the frame and are rotated through 90‹ to hold the member in place; the cover 27 is omitted, and the plate 30 is held down by screws. Fig. 9 shows a device for holding cylindrical articles 1<a>, rubber ring 33a gripping the inside of the article. In another form of holder, the articles are held by sliding jaws having V-shaped slotted ends to grip opposite sides of the article. A modified form of guide table is shown in Fig. 12, wherein two methods of securing the members 13<a> to the part 14 are shown.

Title: Methods of drawing metals
IPC: B21D22/28
Filed: 1922-07-04
Abstract: 182,795. Schrader's Son, Inc., A., (Assignees of Kraft, H. P.). July 7, 1921, [Convention date]. Drawings to Specification. Cupping.-Cupped sheet metal articles of brass or like difficultly drawable metal such as dust caps for tyre valves, in which the depth is considerably greater than the diameter, are made by forming a preliminary cup and passing the cup through a series of successive drawing operations each of which lengthens the - cup not exceeding approximately one-eighth of an inch, so as to avoid the necessity for annealing between each stage. Each drawing operation is also arranged to reduce the diameter of the cup not exceeding approximately one-sixteenth of an inch. The shallow cup is made by stamping from a flat disc and then preferably annealing. The amount of lengthening and reduction of diameter may be lessened in succeeding stages. Thus for the first three stages the reduction may be onesixteenth of an inch, the second three one-thirty-second of an inch, the next one or two one-fiftieth of an inch, and the next four or five one-hundredth of an inch. The lengthening may be one-eighth of an inch for the first three stages, one-sixteenth of an inch for the next three, and one-thirty-second of an inch for the next five or six. The cup may be passed to successive dies either while still hot or after cooling.

Title: Improvements in or relating to radio receiver circuits comprising arrangements for deriving a control voltage from received intermediate or high frequency signals
IPC: H03G3/22
Filed: 1954-06-29
Abstract: 752,034. Automatic gain control. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 29, 1954 [July 2, 1953], No. 19028/54. Class 40 (5). In an automatic gain control circuit a seriestype limiter is used to prevent inpulsive noise affecting the automatic gain control. The diode A.G.C. detector 2 is direct-coupled to a cathodefollower 4, and the output across the resistor 5 fed to a series limiter comprising a diode 6. The cathode circuit of the diode 6 comprises an R.C. network 7 of such time-constant that the diode, which is normally conductive, becomes non-conductive during noise peaks. The noisefreed voltage is smoothed by a filter network 8 and applied to the controlled stages over a further cathode-follower 10. The cathode of the A.G.C. detector 2 is returned to the cathode of the valve 10; in this way a delay bias is obtained which decreases with increase of signal strength. In a simplified embodiment, Fig. 1 (not shown), the second cathode follower is omitted and the detector operated without the delay, its cathode being returned to earth.

Abstract: 619,674. Resin-bonded fibrous laminates. THURSTON, A. P. (Owens-Corning Fiberglas Corporation). July 25, 1945, No. 19043. [Class 140] A laminated product is made by arranging glass fibres in parallelism and lateral contact to form a thir web, impregnating the web with ar incompletely cured thermosetting resin to fill all voids between the fibres, superposing a plurality of such webs and completing the cure. Apparatus for making the web comprises Fig. 1, a bushing 12 provided with small orifices through which molter glass flows. The fibres are collectec into a strand by a guide 18 and wounc on a drum 14. Preferably relative movement is established between the drum and bushing parallel with the axis of rotation of the drum. Simultaneously the resin, which may be in solution or in a heated tacky state is sprayed or brushed on to the fibres The web is then cut along a line extending lengthwise of the drum and rolled into a plane sheet. In a modification, Fig. 4, molten glass from a bushing 26 streams through a blower 27 which ejects a blast of gas engaging and attentuating the streams into fine fibres 28. These are built up on a drum 29 into a thin web 31 in which the fibres extend haphazardly. This web is drawn out to form a sliver 32 of interiaced parallel fibres which is wound on to a second drum 33 and treated as above. For large sheets, the apparatus of Fig. 7 may be employed in which continuous glass fibres or slivers of staple glass fibres are drawn from warper beams 41 when the warps combine and pass about a cylinder 46 submerged in a bath 47 of resin and through a drying chamber 51. In laminating, two or more of the impregnated sheets, which may be further treated with resin or solvent, are superposed, preferably in different directions, and subjected to heat and pressure. Phenol-formaldehyde and urea-formaldehyde resins are specified. Reference has been directed by the Comptroller to Specifications 449,223. 563,043, 564,352 and 569,663.

In the manufacture of rubber hose by the method in which a rubber tube is vulcanized while it is supported internally on a mandrel and subjected to pressure externally, a sheath 10 of braided fine wire is drawn on the tube on the mandrel 16 (or the tube and mandrel are inserted in the sheath), a die 17, preferably of semi-hard rubber, having a diameter smaller than that of the sheathed tube is drawn along the sheathed tube (or the sheathed tube is drawn through the die) to extend the braided sheath, reduce its internal diameter and so apply pressure to the tube, and to lock the component wires of the sheath behind the die, this locking is maintained during vulcanizing of the tube, and, upon completion of vulcanization, the die is withdrawn and the sheath expanded to permit removal of the vulcanized tube and its mandrel. The braided .sheath may be closed at one end and there secured to a bolt 14 on a shank 12.
