Title: Apparatus for measuring cross-talk in transitory state
IPC: H04B3/46
Filed: 1952-07-14
Abstract: 701,492. Cross-talk measurements. COMPAGNIE GENERALE D'ELECTRICITE. July 14, 1952 [July 20, 1951], No. 17703/52. Class 37 In order to measure the cross-talk between two circuits, an alternating voltage is applied to one of the circuits and a cathode-ray oscillograph is arranged so that it can be connected either to the input of this circuit, through a calibrated adjustable attenuator, or to either end of the other circuit. An adjustable frequency generator 1 supplies a sinusoidal voltage to a limiter 2, the output of which is applied through an amplifier 3 to the near end A of the disturbing circuit 4, which is terminated at it far end B by a balancing device 12. The output of the amplifier 3 is also connected to a calibrated network 5, giving an adjustable attenuation, which can be connected through a two-way switch 8 and an amplifier 7 to the deflecting plates of a cathode ray oscillograph 9. The disturbed circuit 6 is closed at its ends A, B by balancing devices 14, 13 adjusted to its characteristic impedance. A time-base 11 supplied by a fraction of the voltage of the generator 1 provides the horizontal sweeps of the oscillograph. A device 10 connected to the Wehmelt cylinder of the oscillograph 9 eliminates the negative half-cycles of the voltage. For measuring far-end cross-talk the end B of the disturbed circuit 6 is connected through the balancing device 14, switch 8, and amplifier 7 to the oscillograph 9 and the peak voltage observed on the screen. The switch 8 is then changed over to connect the attenuator 5 to the amplifier 7 and the attenuator is adjusted  until the same peak voltage is produced, the cross-talk being obtained from the reading of the attenuator. To measure near-end crosstalk the near end A of the circuit 6 is connected to the balancing device 14 and a similar measurement is made. The position of voltage peaks on the screen enables the distance from the end A of fault couplings between the circuits 4, 6 to be obtained.

Title: Process for manufacturing single-crystal magnets
IPC: C22C38/10
Filed: 1960-05-19
Abstract: Iron-nickel-aluminium magnet alloys are given a monocrystalline structure by heating under such conditions that gamma-phase is precipitated, thereby introducing internal strain into the structure, and then further heat treating the alloys at a recrystallization temperature to bring about crystal growth and to redissolve the gamma-phase.  Re-precipitation of the latter is avoided by rapid cooling through the relevant range of temperature. The process is facilitated by inclusion in the alloy of a gamma-phase precipitant selected from carbon, nitrogen, manganese, ruthenium, rhodium, palladium, rhenium, osmium, iridium, platinum and gold, preferably in an amount of 0.03-1.8%. To develop the desired orientation heat may be preferentially withdrawn from one face of the magnet casting during solidification and is similarly supplied to one face during recrystallization. Compositions particularly referred to are .Ni.10-30 .Al.6-14 .Co.5-42 .Cu.0-8 .Ti.0-10 .additional elements,. .e.g. Si, Zr, Nb.0-5 .Fe.balance and these are heated at 930-1175 DEG C. to bring about gamma precipitation followed by recrystallization at 1220-1320  DEG C.

Title: A process for the preparation of endocylic polyols
IPC: C07C31/27
Filed: 1954-06-18
Abstract: Endocyclic polyols and diols are prepared by reacting an ethylenically unsaturated endocyclic aldehyde or ketone with carbon monoxide and hydrogen under increased pressure and at elevated temperature in the presence of a cobalt catalyst to effect hydroformylation, and subjecting the hydroformylation product to a subsequent catalytic hydrogenation.  Endocyclic aldehydes and ketones which may be used are bicyclo - (1,2,2) - hept - 5 - ene - 2 - aldehyde and its 3-methyl-, 3-isopropyl-, 3-phenyl-, 2-methyl-, 3-methyl-2-ethyl-, 4 : 7 : 7-trimethyl-, and 3 : 4 : 7 : 7 - tetramethyl - derivatives, bicyclo - (1,2,2) - hept - 5 - ene - 2 - one and its 4 : 7 : 7 - trimethyl - derivative, bicyclo - (2,2,2)-oct - 5 ene - 2 - aldehyde and its 3 - methyl - derivative, bicyclo - (2,2,2) - oct - 5 - ene - 2 - one, cyclopentadienequinone, cyclohexadienequinone, bis - cyclohexadienequinone, the 2-acetyl-, 2-benzoyl-, 3-methyl-2-acetyl-, 7 : 7-dimethyl - 2 - acetyl - and 2 - (hexahydrobenzoyl)- derivatives of bicyclo-(1,2,2)-hept-5-ene, and the 2-acetyl- and 3-methyl-2-acetyl-derivatives of bicyclo-(2,2,2)-oct-5-ene.  The hydroformylation step may be carried out discontinuously or continuously at a temperature between 100 DEG and 225 DEG  C., at pressures between 100 and 700 atmospheres, using the cobalt catalyst in the form of the metal or as a cobalt compound such as cobalt carbonyl or cobalt carbonyl hydride.  The ratio of carbon monoxide to hydrogen may vary from 4 : 1 to 1 : 4 and solvents such as dioxane, benzene, toluene, heptane, octane, cyclohexane, ether and saturated alcohols may be used.  The hydroformylation products contain the corresponding dialdehyde or keto-aldehyde formed by addition of the formyl group to the unsaturated endocyclic aldehyde or ketone and hydrogenation of the double linkage, and may also contain saturated and unsaturated alcohols and aldehyde-alcohols.  The crude hydroformylation product is then hydrogenated in the presence of hydrogenation catalysts such as copperchromium catalysts to form the corresponding diols or polyols which are separated by fractional distillation.  In an example, bicyclo(1,2,2) - hept - 5 - ene - 2 - aldehyde is dissolved in dioxane and subjected to the process of the invention to yield finally a mixture of diol isomers having the empirical formula C9H16O2.

Abstract: 566,346. Copying in colour by scanning. STEVENS, A. H. (Interchemical Corporation). Dec. 30, 1942, No. 18521. [Class 40 (iii)] An apparatus for making the four separation images for a four-colour reproduction process comprises three separate photo-electric receptors upon which the three different spectral components of a coloured subject are directed and means for selecting at each instant the greatest of the three responses of the receptors to produce an achromatic separation image, in combination with means for producing and utilizing the differences between each selected response and the concurrent individual response of each photo-electric receptor to produce three chromatic separation images. In the apparatus shown in Fig. 1, the three outputs of the three photo-electric receptors are fed at A<1>B<1>, A<2>B<2>, A<3>B<3> to three rectifiers E<1>, E<2>, E<3> connected as shown with a common load resistance R. The voltage across the load resistance R is at any instant that due to the greatest of the responses and is used to produce the achromatic separation image. The voltages appearing across each rectifier at r, g and b are the differences between the greatest response and the individual responses and are used to produce the chromatic separation images. In two other apparatus, the photo-electric receptors, which may be electron multipliers or photoelectric cells associated with amplifiers, feed the three rectifiers through potentiometers enabling separate adjustments of the colour outputs. In a fourth apparatus, Fig. 4, the feed to the separate rectifiers 29, 30, 31 includes separate adjustable potentiometers 23, 25, 27, and also cross-connected circuits between the several photo-electric receptors 151, 171, 191 and each individual rectifier in order to introduce additive or subtractive colour corrections as explained in Specification 506,259.
