Abstract: 949,938. Variable-speed ratchet gear; universal Joints. R. GIRARDELLI. July 7, 1960 [July 9, 1959], No. 23823/60. Headings F2D and F2U. A steplessly variable ratchet gear uses cyclic variations of parallel univeral joints 9 to control the speed of a carrier 42 of stepped planets L, M meshing suns B, N respectively on main driving and driven shafts 8, 45. The universal joints comprise two or more joints of the kind having transverse pins 23 on one member engaging circular grooves 26 in the other, the joints being equiphased circumferentially to produce phased fluctuations. The common input 11 of the joints is driven by the main driving shaft 8 through bevel gears A, D, E, F, which permit angular adjustment of the joints the outputs 18, 181 of which are connected through friction ratchets 39 and a gear pair G, H to the planet carrier 42. The gear sizes are such that in the aligned position of the joints 9, carrier 42 rotates forwards and the driven shaft 45 is stationary. As the joints are adjusted angularly the rotation of the carrier 42 is restrained in correspondence with the minimum instantaneous velocities of the joints 9; thus retarding the carrier and causing the driven shaft 45 to be driven with gradually increasing speed.

Title: Improvements in and relating to devices for regulating the amplitudes and damping insound apparatus
IPC: H04R1/22
Filed: 1920-08-16
Abstract: 150,265. Signal Ges. Aug. 18, 1919, [Convention date]. Receiving and detecting audible signals; subaqueous audible signals.-In apparatus for producing and receiving sound vibrations, of the kind in which means are used for transforming the amplitude of vibration as, for example, in detecting subaqueous sound wherein the smallamplitude vibrations of a diaphragm in contact with water are converted into vibrations of greater amplitude to affect a microphone or other detector, the transformation has been obtained by the use of a lever or equivalent vibratory device such as a tuning-fork, or by the use of a vibratory structure comprising two or more masses connected by elastic members. In the latter case owing to the masses used, a definite transformation ratio involves, within limits, a definite damping effect. The present invention combines the use of levers and vibratory structures so that the amplitude transformation and damping can be adjusted independently. In one fcrm, a lever with fulcrum at one end is connected between its ends with the centre of a sound-receiving or emitting diaphragm, and the free end of the lever carries a vibratory structure in the form of an electro-magnetic sound producer or detector, of which the magnet and armature constitute the masses of the structure. In another form, Fig. 2, the lever device consists of a diaphragm 12 with radial stiffening-ribs connected with the sound producing or receiving diaphragm 1 by an interposed forked member 10 as shown. The vibratory structure comprises masses 6, 7 forming respectively the magnet and armature of an electro-magnetic vibrator, connected by a rod and surrounding tube secured respectively to the masses 6, 7 and connected togther at their free ends 8<a>. For receiving purposes, the electro-magnetic vibrator may be replaced by a microphone the electrodes of which constitute the masses of the vibratory structure. Fig. 4 shows an arrangement for receiving sound in air in which the amplitude is reduced before affecting the microphones. A receiving diaphragm 1 with radial ribs 14 is connected by a forked member 10 with a vibratory structure comprising a bar 20 having weights and microphones 18, 19 mounted at its free ends.

Title: Improvements in the production of sulphonic acids
Filed: 1927-09-12
Abstract: 303,917. Johnson, J. Y., (I. G Farbenindustrie Akt.-Ges.). Sept 12, 1927. Samples furnished. Emulsions, making.-Sulphonic acids useful as emulsifying agents are obtained from unsaturated aliphatic hydrocarbons or their halogen derivatives or from unsaturated hydroaromatic compounds by treating them with sulphonating agents, such as sulphuric acid, sulphur trioxide, and/or chlorsulphonic acid, and an equimolecular amount or more of an organic acid, acid anhydride, or acid chloride or of phosphoric acid ur its anhydride or chloride. The reaction may be applied to the individual hydrocarbons or compounds or to mixtures containing a preponderating proportion thereof such as petroleum or its cracking products or brown-coal tar oils such as gas oil, yellow oil, and solar oil; such mixtures may be treated directly or after enriching or isolating their olefine constituents. In one example, tetrahydrobenzene is treated with a mixture of sulphuric acid and acetic anhydride and the reaction product is diluted with water, heated to remove acetic acid, and neutralized. Derivatives of unsaturated hydroaromatic hydrocarbons, such as the corresponding napbthenic acids, may be treated in the same way. In another example, propylene is led into a mixture of sulphuric acid and acetic anhydride and the mixture is allowed to stand. The reaction product so obtained is worked up by diluting with water, boiling under reflux, and distilling off acetic acid. The sulphonated propylene can be recovered from the solution as calcium or sodium salt. Higher homologues or propylene or halogen derivatives of the olefines such as trichlorethylene. may be treated in the same way.
