Filed: 1952-12-17
Abstract: 729,956. Electromagnetic brakes and couplings; magnetic compositions. EATON MANUFACTURING CO. Dec. 17, 1952, No. 31972/52. Classes 35 and 38 (2). A magnetic fluid clutch or brake comprising a first member in the form of concentrically spaced inner and outer cylinders and a second member in the form of a cylinder or cylinders disposed between the said inner and outer cylinders, the magnetically susceptible fluid being situated in the gaps between the cylinders, is characterized by an annular field coil being situated in a recess in the first member opposite to the open end or ends of the cylinder(s) of the second member. In one form of clutch, Fig. 1, a driving (or driven) shaft 1 and driven (or driving) shaft 3 carry respectively, magnetic members 5, 21 and 29 with cylindrical air-gaps therebetween containing a magnetic fluid mixture of iron particles in a silicone grease base in the ratio 3: 1 by weight. A coil 9 is energized to couple the parts. A non-magnetic ring 49 of mica separates the members 5, 21 and, being of high reluctance, opposes the continuance of a magnetic field due to residual magnetism when the coil 9 is not energized, thus ensuring complete freedom of rotation between the driving and driven shafts under these conditions. Seals 41, 45 prevent escape of the magnetic fluid mixture. The inner cylindrical faces of the members 5, 29 are provided with grooves 17 into which the magnetic fluid is thrown by centrifugal force when the clutch is disengaged, as shown in Fig. 3, insufficient fluid being present to connect the cylindrical parts under these conditions. In modifications (Figs. 5 6 not shown) the driving and driven members carry a plurality of interengaging coaxial cylinders of different diameters. In a further modified form, the member 29, Fig. 7, is provided with a radial passage 81 connecting the magnetic fluid in the gaps at its inner and outer sides and a groove 87 and raised edge 89, Fig. 8, on the outer surface of the cylinder 29 turns into the end thereof. A magnetic fluid consisting of a mixture of iron filings and graphite powder in the ratio 1: 1 by volume is used, and the passage 81 &c. circulates this mixture between the two gaps, sealing means being omitted from the left-hand end of the member 29. Specifications 649,553, and 677,534, [both in Group XXIV], are referred to. Reference has been directed by the Comptroller to Specification 690,060.

Abstract: 740,521. Reciprocating generators. BOSCH GES., R. Nov. 19, 1953, No. 32051/53. Class 35. A reciprocating ignition generator for use as a gas lighter &o. has a reciprocating magnetic part 13 the movement of which causes a change of flux which in turn induces an E.M.F. in the ignition winding which is so located so as to surround the air gap formed between the reciprocating part 13 and a fixed pole piece. The current impulse thus produced is further assisted by an interruption of the primary winding 16 by a switch 21 which is opened at the appropriate time by an abutment 22 carried by a ram 19. The latter, which moves the reciprocating part 13, is actuated by a cam 17. The magnetic flux is produced by a permanent magnet 12 located in the stator, but as shown in Fig. 3 the device may have a fixed permanent magnet 40 and a moving one 41 constituting the reciprocating member.

Title: Process for the manufacture of aromatic ethers
IPC: C07C205/38
Filed: 1975-07-31
Abstract: Aromatic or heteroaromatic ethers are obtained by reacting a water-immiscible activated aromatic or heteroaromatic halide with an alcohol. The reacting halogen atom has to be bonded to an aromatic or heteroaromatic ring carbon atom and the reaction itself has to be carried out in the presence of an aqueous alkali and of a phase transfer catalyst. Cyclic aromatic ethers are prepared when the hydroxy compound is itself a substituent of the aromatic halide that is attached to the o-position when the aromatic halide is a benzene derivative or the ortho- or peri-position when the aromatic halide is a naphthalene derivative. In this case an intramolecular etherification takes place. The ethers prepared are usable inter alia as dye intermediates.

Title: Method of, and means for, maintaining secrecy in the transmission of wireless telegraphic messages
IPC: H04L9/38
Filed: 1929-10-24
Abstract: 341,568. Wireless signalling. BROENTJES, W., 40, Volkerakstraat, Amsterdam. Oct. 24, 1929, No. 32351. [Class 40 (v).] In a system of secret wireless telegraphy transmission, one group of working frequencies is used for the signals and one group of open-circuit frequencies between the signals, the working and open circuit frequencies being interchanged at will amongst themselves and as groups during transmission. The groups of frequencies used are known to the sender and receiver alone, and are transmitted directly or as modulations of higher frequencies. The changes are effected manually or automatically after a warning signal. In the arrangement shown, the anode inductance tappings 13 .. 18 are connected to a disc switch having a rotating arm M which successively connects various tappings across combinations of the variable condensers kl, k<2>, k<3>. The contact arm M is rotated step by step by a toothed disc B actuated by an escapement D which is in turn controlled by coils W2, W1, respectively energized by the working contact and " open circuit " contact of the transmitting key S. A different frequency is transmitted for each step of the arm M, the tappings 13, 15, 17 determining the open-circuit frequencies and 14, 16, 18 the working frequencies. The open circuit frequencies may be given the character of working waves by interrupters o<1>, o<2>, o<3>, which may be short-circuited by switches s, s<2>, s<3>. The opencircuit and working frequencies may be interchanged by change-over switches c<1>, c<2>, c<3>. A tuned intermediate circuit, similarly controlled by a switch arm actuated by the disc B, may be provided between the aerial and anode or grid circuit of the valve Z, in which case the condensers k<1>, k<2>, k<3> should be mechanically coupled to those of the intermediate circuit. The receiver has a number of tuned circuits, one for each working frequency, connected to a common detector valve so that it is unaffected by change from one working frequency to another.
