Filed: 1973-07-23
Abstract: 1379216 Nacreous pigments MERCK PATENT GmbH 23 July 1973 [9 Sept 1972] 34956/73 Heading C4A Gold-coloured nacreous pigments comprise mica flakes having a coating containing TiO 2  and/or ZrO 2 , and in addition ferric oxide produced by oxidation of a deposited ferrous hydroxide layer. The ferrous hydroxide is precipitated on the mica substrate at a pH above 5 from an aqueous ferrous salt solution and then converted to ferric oxide by oxidation and dehydration. The ferrous salt may be the sulphate or oxalate, a halide, or ferrous ammonium sulphate. The pH value is controlled by the addition to the hydrolysis solution of an alkali metal or ammonium hydroxide or gaseous ammonia, and optionally a buffer system comprising for example, an acetate or glycocoll. The oxidation of the ferrous ion is preferably effected by air; in a preferred embodiment, it is initiated in the precipitation solution simply by stirring or by passing in air, and then completed by drying in air. Alternate methods include effecting the coating in a nitrogen atmosphere and oxidizing subsequently, and using hydrogen peroxide, ammonium nitrate, or permanganate as oxidizing agents, added to the reaction mixture after precipitation or to the wash water. The mica substrate may be flakes 5-250 microns in diameter and 0À1-5 microns thick coated with 100-300 mg. TiO 2  per sq. metre of mica surface area. Ferrous hydroxide may be precipitated thereon in an amount such that the calcined pigment contains up to 20% by wt. ferric oxide.

Filed: 1947-12-31
Abstract: 655,578. Voltage measuring. DRECHSLER, R. Dec. 31, 1947, No. 35065. [A Specification was laid open to inspection under Sect. 91 of the Acts on Dec. 31, 1947.] [Class 37] The vectors of an A.C. voltage Ex, Fig. 1, are measured by two balanced bridge circuits 1, 2, 3, 4 and 1<SP>1</SP>, 2<SP>1</SP>, 3<SP>1</SP>, 4<SP>1</SP>, each having two arms 3, 4 and 3<SP>1</SP>, 4<SP>1</SP>, constituted by rectifiers, the diagonals 13, 14 and 13<SP>1</SP>, 14<SP>1</SP> of each bridge being fed with the voltage Ex, in series with galvanometers 6, 6<SP>1</SP>, while the diagonals 11, 12 and 11<SP>1</SP>, 12<SP>1</SP> are each fed with voltages Ep1, Ep2 in quadrature and of the same frequency as Ex ; if the phase of voltage Ep1 is taken as the phase of that component of Ex due to ohmic resistance, galvanometer 6 registers proportionately to that component, while meter 61 registers proportionally to the reactive component of Ex. As applied to measuring the errors of transformers, a standard transformer N, Fig. 4, has its primary in series with the primary of the transformer X under test, and its secondary in series with a resistance R% and the secondary of transformer X; the circuit W, J is as in Fig. 1, and is first fed from resistance R% to allow Ep1 to be adjusted to be in phase with the potential across R%, and then the potential across Rn is applied in place of that across R%, when the instrument W (6 of Fig. 1) registers proportionally to the ratio error; if now Ep2 is applied, instrument J (6<SP>1</SP> of Fig. 1) registers proportionally to the phase error. A standard resistance R%, Fig. 5 (not shown), may replace the standard transformer. As applied to measuring the phase angle of a condenser Cx, Fig. 6, the voltage drop across Rn1 fed over a standard condenser Cn is first used to set the instrument, and the voltage drop across resistance Rn2 fed from condenser Cx is then applied to the instrument. As applied to the determination of the resistive and reactive components of an impedance, the unknown impedance Z, Fig. 7, is connected in series with a standard resistance Rn and a condenser (not shown); the instrument is set by bringing Ep1 into phase with the voltage drop across Rn, so that when the voltage drop across Z is applied, the instrument registers resistive impedance when Ep1 is applied and the reactive impedance when Ep2 is applied. According to the Specification as open to inspection under Sect. 91, voltages Ep1, Ep2 may be applied in succession to a single bridge at Ep, Fig. 1a (Cancelled), instead of simultaneously to two bridges, the voltage Ex being applied across a resistance Rn, or in series with the meter G, or derived from a potentiometer; this subject-matter does not appear in the Specification as accepted.

Filed: 1957-11-19
Abstract: 838,465. Code telegraphy. FISHER, C. B. Nov. 19, 1957, No. 36048/57. Class 40 (3). In a receiving arrangement for D.C. telegraph signals comprising a polarized relay having an operating winding and a differential winding with the input signals applied directly to the operating winding, the differential winding is included in a branch circuit arranged to produce a substantially steady current from the received pulses, and the winding is designed to produce a magneto-motive force approximately one half of that produced by the full amplitude of the current pulses in the operating winding and applied in opposite sense to the relay. The received signals are passed via input circuit 9 and conductors 11, 11<1> to the operating winding 1 of a polarized relay 6 having its armature extension 19 vibratable between contacts 20, 21 so that ground or positive potential from battery 22 is applied to the line 23. The current through the winding 1 serially passes through the primary winding 3 of a transformer 12. The incoming signals of positive polarity are passed via rectifier 16 and rapidly charge up a capacitor 13 which through rectifier 14 and resistor 15 provides a substantially steady current through the biasing winding 2 and a secondary winding 4 of the transformer 12. The number of turns of the secondary winding 2 is chosen in relation to the current to produce on the armature 7 a magneto-motive force equal to half that produced by the current simultaneously passing through the main winding 1. The mutual inductances of the windings 1, 2 and 3, 4 respectively are chosen to be equal so that the voltage induced in the secondary winding 4 is equal in magnitude to that induced in the biasing winding 2 of the relay and is in opposition thereto in the biasing circuit. The constants of the discharge circuit are such that the current from the capacitor 13 is maintained substantially constant over a period greater than the duration of the longest spacing interval or condition occurring during signal reception. A third winding 8 connected through a variable resistor 17 to a battery 18 may be employed to adjust the operating point of the relay 6. In a modification, Fig. 3 (not shown), the transformer 12 is replaced by a single-wound coil arranged to have a self inductance equal to the mutual inductance of the primary and biasing windings 1, 2 of the polarized relay 6.
