Title: Improvements in electric vibrators, more particularly vibrators for sound recording
IPC: B43L25/02

Abstract: 419,683. Current and pressure meters. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. Aug. 23, 1933, No. 23471. Convention date, Sept. 16, 1932. [Class 37.] Apparatus particularly suitable for soundrecording, having a vibratory reed the free end of which acts as a pivot for a mirror or like vibration-reproducing member, is characterized in that one portion of the reed is rigidly mounted equidistantly between portions of magnetic polepieces, while the vibration-reproducing member is carried by a flexible support extending on either side of the reed in the direction of vibration, and acting to retain the said member in pivotal contact with the reed. In the apparatus shown, a silicon steel reed 6 is clamped between polepieces 4, 5 of the same alloy by spacers 7, the polepieces being carried by permanent magnets 2, 3. Two coils 9, 10 surround the reed, one of which serves to carry the acoustically-modulated currents representing the sound to be recorded, while the other carries a biassing current supplied by an " antigroundnoise " amplifier. The free end of the reed is formed as a knife-edge, with which pivotally engages a small plate 13 fixed to a mirror 11, the mirror being carried by a metal strip 12. This strip, which is preferably of phosphor-bronzee, has its ends fastened to prongs 14, 15 which extend down from a curved member 16 and press against the polepieces. A screw 17 is provided to flex the member 16 and, by thus shifting the prongs 14, 15, to adjust the tension of the strip 12. An adjustable magnetic shunt 19 is provided, to centre the reed between the polepieces, and the reed may be damped by means of a disc of rubber 20. In use, vibrations of the reed cause corresponding magnified vibrations of the mirror, which may be utilized to produce a record of the variable-area type. The reed 6 may be made relatively stiff, so that the system has a high natural frequency.

Title: Improvements in or relating to methods of carbonising metals
IPC: C23C8/66
Filed: 1934-08-16
Abstract: 442,878. Carbonizing metals; producing oxide surfaces. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.- (Assignees of Eddison, C. ; 63, North Walnut Street, East Orange, New Jersey, U.S.A.) Aug. 16, 1934, No. 23669. Convention date, Aug. 16, 1933. [Classes 72 and 82 (ii)] In a method of carbonizing metals such as iron, copper, nickel and tungsten, the surface of the metal is coated with a mixture containing finely divided carbon and a carbonaceous binder and the coated metal heated at a temperature below the formation temperature of carbides of the metal to decompose the binder. The surface of the metal is roughened, e.g. by etching sand or steel blasting, and, if desired, oxidized, before coating. Binders such as palmitic acid and lard oil may be used, and these may be dissolved in a hydrocarbon solvent such as alcohol and formed into a solution with lamp black, or with which the metal is sprayed or painted or the binder may be mixed with the lamp black to form a paste. The roughened metal strip 2 from a reel 1 is passed through the paste mixture 3 in a container 4, the excess being removed by knife-edges 5. and rollers 6. The coated strip 8 passes through a small gas flame 9 and then through a furnace 10 maintained at 350-650‹ C., the furnace having an inert atmosphere therein.. The strip is fed through the furnace at such a rate that the binder is decomposed in the furnace. In a modification, the roughened metal strip is passed directly through the furnace 10 containing air and heated to 650‹ C., to produce an oxidized surface thereon. The binder dissolved in a solvent .is mixed with lamp black and the mixture sprayed on the metal strip which is allowed to dry. The coated strip is then passed through the furnace heated to 100‹ C. to cause the coating to flow evenly over the surface and then the thus treated strip is passed through the furnace now heated to 600-650‹ C., and containing an inert atmosphere. The carbonized metals may be used as electrodes in thermionic valves and other electron discharge devices.

Abstract: 1501303 Transporting loads by cableway carriages JAMES JONES & SONS Ltd 8 June 1976 23689/76 Heading B7L In a cableway carriage, a load is carried on one end d of a haul-in line c passing around a capstan drum or pulley which has a brake drum 24 non-rotatably connected thereto, and a mechanism operates to tighten a band 25 around the drum 24 when the tension in the line c exceeds a certain value to thereby brake the drum 24 against anticlockwise rotation so that pulling on the line c moves the carriage along a cable a, b. With a haul-back line e tensioned, pulling on line c causes an arm 7 carrying a pulley 9 to pivot anticlockwise against the action of a spring 8 and, through linkage 23, 22, 21, 14, the band 25 is tightened. When the line c is pulled, the capstan drum can rotate clockwise and the load carried on the end d is lifted, but a fully suspended load tends to rotate the drum anticlockwise which is prevented by the brake. A second haul-in line f may aid paying- out of the line c.

IPC: G05D16/18
Filed: 1953-08-31
Abstract: 769,541. Testing physical qualities of materials. BOULTON PAUL AIRCRAFT, Ltd. Aug. 26, 1954 [Aug. 31, 1953], No. 24016/53. Class 106 (2). [Also in Group XXIX] A changing gaseous pressure employed in load test. ing the strength of a structure is produced by means of a pivoted beam 1 which is balanced by a jockey weight 2 and a gaseous pressure acting in opposition. Movement of the beam resulting from unbalance thereof causes gas to be admitted to, or exhausted from, the system to restore equilibrium, and the jockey weight is adapted to be. driven along the beam by a variable speed electric motor 7 so as to produce a predetermined rate of change of gaseous pressure. The gaseous pressure in the system is applied through a pipe 11 to one end of a telemotor 13, the other end of the telemotor link acting on a piston 15 to raise or lower a yoke 17. A force corresponding to the gas pressure is finally applied to the beam 1 through a push rod 18, an auxiliary lever 20, and a rod 22, and the. proportional amount of the pressure applied can be varied by rotating a cam-shaft 36 so as to select one of a set of fulcra 28 ... 31 for lever 20. Any movement of beam 1 is applied to an hydraulic follow-up servo-mechanism 39 of which the output is applied to lever 40 carrying valves 37, 38 at its opposite, ends. Valve 37, when opened, allows' the supply of compressed gas to the system to raise its pressure, and valve 38, when opened, vents the system to lower its pressure. Friction in the apparatus is prevented by electric motors 43, 56 which rotate, respectively, the master device of the servo-mechanism and the casing of the piston 15. Motor 7 drives the jockey weight through a screw rod 6 and it drives also an electrical transmitter 8, the output of the latter being applied to a repeater motor connected to an indicator. The pressure produced in chamber 10 is applied to a capsule which acts at an intermediate point of a lever fulcrumed at one end on a knife edge. The other end of this lever acts on a further lever which controls a switch connected to an indicator and also a valve controlling the supply of liquid to a jack adapted to apply the required load to the structure. The jack is also connected to the lever to which the capsule is connected so as. to provide a follow-up action. Specifications 693,504, [Group XXIX], 739,398 and 769,540, [Group XXIX], are referred to.
