Filed: 1916-05-03
Abstract: 103,238. Orling's Telegraph Instruments Syndicate, and Orling, A. May 3, 1916. Non-contact-making relays.-A non-contact-making relay controlling a recorder comprises a jet of conducting-liquid impinging upon two separated electrodes connected to the terminals of a battery or to the arms of a wheatstone bridge in such a manner that a movement of the electrodes or the liquid jet causes the current in the line or in the recorder to be varied or reversed. In the arrangement shown in Fig. 1 two carbon electrodes n, connected to a battery e are separated by two porous disks o and one or more sheets of glass p. A jet a of liquid falls upon the separators o, p and is connected through the recorder f to the middle of the battery e, so that when the liquid jet is deflected by the movement of the coil d and rod c the normal balance is upset, due to the changes in the resistances of the streams of liquid passing over the separators o, and current is caused to flow in one direction or the other through the recorder f. In the arrangement shown in Fig. 2, the electrodes n are connected to the arms g, h of a wheatstone bridge so that change or reversal of current takes place in the circuit containing the recorder f and jet a when the jet is displaced. In a modification the external resistances in the arms g and h are omitted. In the arrangement shown in Fig. 5, the liquid jet is divided by two curved plates q, which are in contact over a large area with the leads from the battery e. The plates q may be separated by a mica strip which projects above their upper edges. In the modification shown in Fig. 7 the leads from the battery are connected to plates t placed in porous pots s having inclined edges. Specification 18001/11, which describes a liquid jet recorder and relay, is referred to.

Abstract: 506,859. Sex hormones. SCHERING AKT.-GES. March 1, 1938, No. 6459. Convention date, March 1, 1937. [Class 2 (iii)] 17-Alcohols of the cyclopentanopolyhydrophenanthrene series of low physiological activity are converted into their isomers of high physiological activity by a process comprising the oxidation of the 17-alcohol to the corresponding ketone, followed by a reduction to give a mixture of cis- and trans-17-alcohols, from which the isomer of high physiological activity is isolated. The preferred oxidizing agent is chromium trioxide,. but the oxidation may also be carried out by treatment with an excess of a ketone or aldehyde in the presence of a metal alcoholate such as an aluminium alcoholate. The preferred reducing agents are those described in Specification 449,461. In the case of compounds possessing smaller double bonds, these are preferably protected by halogenation during the oxidation, and in the case of oestradiol compounds, the phenolic hydroxy group is protected by esterification or etherification. The preferred method of separation of the isomers is by the use of digitonin as described in Specification 459,759. In examples : (1) a cistrans oestradiol mixture is. benzoylated, oxidized with chromic acid in glacial acetic acid. and then reduced according to Specification 449,461. (2) Androsten-3-trans-17-cis-diol is oxidized with aluminium isopropylate in cyclohexanone and reduced as in example (1), (3) Androsten-3- trans-17-cis-diol is oxidized with intermediate protection of the nuclear double link by bromine and then reduced as in example (1)., (4) Androsten-3-trans-17-cis-diol-3-acetate is oxidized and reduced as in example (2). (5) 3- Trans-17-cis-androstendiol is oxidized with intermediate protection of the nuclear double link as in example (3), reduced with zinc dust, and the isomers separated by means of digitonin. Specifications 435,563 and 448,225 also are referred to.

Title: Navigational system
IPC: G01S19/21
Filed: 1946-03-05
Abstract: 626,301. Electric indicating systems. DUGGAR, L. G. March 5, 1946, No. 6813. Convention date, March 5, 1945. [Class 40 (i)] In a navigational aid device the location of a' vehicle, such as an aircraft, relative to two radio stations is established by two indicators, each controlled jointly by an individual directional loop aerial and in electrical control such as a remote reading gyro compass. In the system shown in Fig. 1, the compass 19, through amplifier 20, electrically influences the stator 18 of a motor Selsyn 16 whose rotor 17 is accordingly orientated to position the stator 14 of a transmitting Selsyn 12. The associated rotor 13 is positioned by the loop aerial 10 and the transmitter signals are passed to a remote indicator 23 having a pointer 24. The indicator 22 is similarly controlled by the compass 19 and loop 10a and the intersection of the two pointers indicates the position of the aircraft relative to the transmitting stations, represented by the pivots of the indicators 22, 23. In the form of indicator described, light beams are used as pointers. Light from a lamp 68, Fig. 6, is concentrated by a condenser 72 and passes through a tube 78, secured to Selsyn rotor 24, to a concave reflector 83 so as to throw a narrow beam across the main dial of the instrument. A subsidiary dial 40 is fixed on a loose pinion 59 which meshes with an idler pinion 56, in turn engaging a fixed pinion 46. The whole of the Selsyn and indicator assembly is carried on a frame 47 which is rotatable about the fixed stem 44 by means of a pinion 51, Fig. 5, engaging a rack 49. This arrangement ensures that the two subsidiary dials maintain constant direction irrespective of orientation of the frame 47 carrying them. In use, the frame carrying the indicating Selsyn assemblies is rotated until the line 35, Fig. 4, joining the two indicators, corresponds to the azimuthal relation of the two transmitting stations (120 degrees in the Figs.). The intersection of the two light beams shows the relative position of the aircraft. A map of suitable scale may be placed on the dial to give the exact position.
