Title: A sound generator
IPC: G10K9/06
Filed: 1964-03-25
Abstract: 1,031,404. Sound generators. MESSERSCHMITT A.G. March 25, 1964 [May 6, 1963], No. 12513/64. Heading G5J. A high power sound generator for sonic fatigue testing of materials comprises a piston 2 driven by a piston motor 1 to reciprocate in a cylinder to which is attached a soundtrumpet 10. In the first embodiment (Fig. 1), the motor piston 1 acts as a valve to admit fuel via port 5 into, and remove exhaust gases via port 6 from, alternate halves 4, 4<1> of the motor cylinder. If the diesel combustion cycle is used, the ignition plugs 7 are replaced by fuel injection nozzles and air only is drawn in through port 5. In a second embodiment (Fig. 2, not shown), the sound producing cylinder 8a is between two alternately acting motor cylinders, the pistons in which drive the sound producing piston via a common connecting-rod. The motors have transfer ducts and work in the conventional two-stroke manner. In a third embodiment (Fig. 3, not shown), a piston motor mounted inside the cylinder 8b works against a buffer piston 2. The motor operating frequency may be modulated by introducing compressed air through an inlet 14 into the buffer space. In a fourth embodiment (Fig. 4, not shown), two free-piston motors are mounted in axial alignment transverse of the sound tube 9<1>, 10 and drive pistons 2<1>, 2<11>, preferably mounted at an angle to the axis of the sound-producing cylinder, in antiphase. In all four embodiments the frequency of operation is adjusted by varying the fuel supply rate and mixture, and the sound spectrum is modified by varying the effective length of the trumpet 10 telescopically and introducing a stream-lined body 11 into the trumpet. Rapid frequency variation is possible due to the low inertia of the free-piston system.

Title: A method and apparatus for transmitting fluids
Filed: 1960-04-08
Abstract: 948,446. Fluid ducts. SOCIETE LAB. April 8, 1960 [April 9, 1959; Feb. 29, 1960], No. 12516/60. Heading F2R. Loss of head and the formation of eddies in fluid flow where the flow path changes from rectilinear to curvilinear or vice versa, are reduced by effecting such conversion between dynamic pressure energy and static pressure energy within layers of the fluid taken parallel to the axis of curvature of the curvilinear flow, that the conditions of dynamic and static pressure in such layers satisfy the conditions for irrotational flow about the axis. Fig. 3 shows a duct having an 180 degree bend. A Venturi section at the inlet to the bend is formed by a member 4, and one at the outlet from the bend by a member 5. In each case, a member 13, 18 having the profile of the upper surface of an aircraft wing is superimposed on the member 4, 5, respectively. The overall effect is that throughout a cross-section of the flow in the bend taken perpendicular to the centre line of the duct, the total pressure, including pressure due to centrifugal effects in non-rectilinear flow, is constant. The formation of eddies, and pressure head losses, are stated to be reduced. In Fig. 7, the Venturi sections are formed by members 40, 50, placed on the inner wall of the duct, and each having their exposed surfaces contoured like the upper surface of an aircraft wing. Other embodiments, in each of which the cross-section of the flow is reduced by a partaerofoil member in a duct containing the fluid, are described.

Filed: 1917-08-31
Abstract: 109,270. Singer, L. July 3, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Resins and resinous compounds. - Acid resins obtained in the treatment with sulphuric acid of hydrocarbons, especially mineral oils, are treated, while fresh, to separate oils, a resinous product which may be used in printing-ink, and sulphuric acid which may be used again or neutralized with ammonia to form ammonium sulphate. The separation is effected by fractional washing with solvents such as methyl or ethyl alcohol, acetone, chlorhydrocarbons such as carbon tetrachloride, di-, tri-, or per-chlorethylene, tetra- or pentachlorethane, or by successive washings with two or more of the solvents. Solutions of oil are obtained in the first washings, and solutions of resin in the later washings. Acid resin from a vessel M, in which hydrocarbons are treated with sulphuric acid, is run into a mixing-vessel WK and mixed with solvent from a cooler and condenser LO. The treated acid resin is run into a second mixer L, in which it is treated with solvent from a cooler and condenser LH, and the lower layer of sulphuric acid is run into a solvent vaporizer VH. The oil solution from the mixer WK is run into a vaporizer VO. Sulphurous acid may be withdrawn and the apparatus kept under diminished pressure by a vacuum pump.

Abstract: 277,616. Abramson, A. Sept. 18, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Addition to 284,791. Differential gearing suitable for motor vehicles allows a limited free rotation of an overrunning axle by the turning out of the way of a driving-pin 28, Fig. 2, with a semicircular driving-part 29. The pin 28 is supported radially in a differential housing 10 so that its inner end 29 engages two double-inclined recesses 30, 30<1> in the heads 7, 7<1> on the front axles 1, 1<1>, respectively. The normal straight drive configuration is shown in Fig. 7. When one head 7 overruns, the semicircular end 29 turns to one side as shown in Fig. 8, and continues to drive the other head 7' only. The differential motion is limited by a through bolt 6, Fig. 1. The deflection of the pin 28 brings a spring 24 to the strained position shown in Fig. 5. This spring opens when possible to restore the double drive.

Abstract: 837,541. Twisting. MORTON MACHINE CO. Ltd. July 31, 1956 [May 3, 1955], No. 12869/55. Class 83 (4). A machine for making twisted metal ties from flat strip stock comprises a pair of aligned spaced chucks for holding end portions of strip stock, and means for rotating the chucks through a predetermined angle to twist said end portions with respect to an intermediate portion of the stock. A metal strip to be twisted is positioned with its end portions in slots 8 of chucks 6, 7 and its intermediate portion in a slot of a member 11. A valve is then operated to supply pressure air to a cylinder 25 to depress a piston rod 24 rigidly connected to a rack 18. The rack 18, through a gear 19, rotates the chuck 6, 90 degrees and through a gear 20, countershaft 21 and gears 22, 23 (Fig. 5, not shown) rotates the chuck 7,90 degrees in the same direction as the chuck 6 to produce a twisted tie, Fig. 6. The rack 18 slightly overtwists the tie and, after the downward stroke thereof has been completed, springs 33 move the rack 18 slightly upwards. A pedal 15 is then depressed to move, through a linkage 13, the member 11 back to release the centre portion of the tie, the tie then falling from the chucks through a shoot 35. To form a tie of the type shown in Fig. 7, the gears 22, 23 are replaced by smaller gears connected by an idler gear and the member 11 is held in its retracted position. Operation of the rack then rotates the chucks 6 and 7 in opposite directions.

Abstract: 101,485. Kunzi, M. Sept. 15, 1915, [Convention date]. Variable-speed epicyclic gearing formotorvehicles is operated by applying a brake to one of two or more sun-wheels, and a solid drive is obtained by frictionally connecting the brake pulleys to the annulus.

[Class 38 (i)] In order to connect a lead to each lamination of a carbon brush 1, hollow rivets 4 corresponding in number to the laminations extend through the thickness of the brush, each rivet being in electrical contact with one of the laminations and having one of the leads attached to it. Each rivet is insulated from the laminations to which it is not desired to make connection by a bush 5 formed by an artificial resin moulded in the hole and subsequently provided with a bore for the rivet. The lead 6 is connected to the rivet either by being gripped in direct contact with the lamination 1 beneath the head of the rivet under which a washer may be placed, or by being inserted in the hollow rivet which is indented to grip it. The former construction is suitable for the outer laminations and the lead may pass from the rivet head through a hole to the upper end face of the brush. In order to prevent shortcircuiting the laminations by the pressing finger resting thereon, a plate of insulating material may be attached to the top of the brush.
