Title: Improvements in and relating to electric transformers, more particularly for toys
IPC: H02K3/20
Filed: 1930-05-05
Abstract: 345,546. Transformers. HOFFMANN, E., 13, Grundstrasse, Oberl÷ssnitz, Radebeul, Germany. May 5, 1930, No. 13803. Convention date, May 4, 1929. [Class 38 (ii).] For protection against overload a transformer has associated with its core the armature of a switching device which is operated by the magnetic flux at overload to break the electric circuit. The Specification describes a number of modifications, In one form shown in Fig. 3 the coils are mounted on a closed core a and the armature b bridges the core between the coils. When an overload occurs the field between the coils increases, the armature is attracted and the primary circuit broken. In a modification of this shown in Fig. 9 the armature b is mounted at one end of a pivoted tube k containing a ball m, and is maintained in either the " on " or "off" " position by the ball assuming a position determined by the inclination of the tube. When the armature is attracted the circuit is broken and remains broken until the armature is reset. In a further modification shown in Fig. 6 a pivoted arm carries two armatures b, e, when overload occurs the attraction on e reduces and on b increases and the lever tilts to break the circuit. In the form shown in Fig. 5 the magnetic circuit is completed through an unbalanced armature b ; when overload occurs the flux reduces and the armature falls away and breaks the circuit. To reset, it is thrown back by means of a lever. In the form shown in Fig. 7, the magnetic circuit is completed through an unbalanced shuttle armature b which moves to break the circuit at overload. The secondary coil is movably mounted on the core a for purposes of voltage regulation and the circuit is completed through a contact g and slide h. The armature is replaced by moving the secondary coil to the right, when a bracket i will move it to the " on " position. The slide h is so positioned that the secondary is disconnected while armature is being restored. In a modification of this the restoring device comprises a knob connected to the armature shaft through a ratchet. The restoring means are adapted to prevent the armature being held in the " on position.

Title: Process for the treatment of petroleum oils
IPC: C10G32/02
Filed: 1959-04-23
Abstract: Oils of reduced metal content are obtained by subjecting a metal-contaminated petroleum oil which includes constituents boiling above 950 DEG  F. to an initial thermal treatment at 600 DEG  to 900 DEG F. for 0,1 to 10 hours and then, at elevated temperature, to a D.C. electrical field.  The thermally treated oil may be diluted with a lighter hydrocarbon, e.g. a 55 DEG -400 DEG F. naphtha prior to the electrical treatment and the mixture may also be treated with an oil-soluble acidic gas, e.g. HCl, SO2, a BF3 before the electrical treatment.  The initial heat treatment may be effected at a pressure of 200 to 1,500 p.s.i.g. The electrical treatment may be effected at 200 DEG  to 400 DEG F. and an applied voltage of 1,000 to 50,000 volts.  The deposited metals may be precipitated from the cathode by vibration or current reversal.  The heat-treated oil should be insulated from direct electrical contact with the ground to avoid dissipation of the charges induced by the heat treatment. Specifications 860,304 and 887,945 are referred to.ALSO:In the purification of metal contaminated petroleum fractions (see Group III) the oil is first subjected to a thermal treatment at 600 to 900 DEG F., which renders the metal-containg particles electrically charged, and then to a D.C. electrical field at elevated temperature. The electrical precipitator may have one or more cathodes, preferably equipped with vibrating means to remove deposited material.  The voltage may be from 1,000 to 50,000 volts.  In examples the precipitators consisted of outer stainless steel cylindrical vessels of (1) 78 mm, (2) 54 mm and (4) 50 mm I.D. as anodes and either (1) and (2) stainless steel fingers of 34 mm. O.D. or (4) a 30 mm. O.D. metal cylinder as cathodes.  In Examples (1) and (2) there was no indicated current and in Example (4) the current was zero at 80 DEG F., 2-4 milliamps at 250 DEG F and 25-45 milliamps at 450 DEG F.  The voltage was 1500 in all three examples.  In a comparative example an A.C. potential of 10,000 volts caused no precipitation. Specifications 860,304 and 887,945 are referred to.

Title: Improved process for refining hydrocarbons
IPC: C10G19/00
Filed: 1922-05-22
Abstract: In the purification of petroleum, benzine, solar oil, paraffin, ceresin, ozokerite, montan wax, and the like saturated hydrocarbons by acid sulphate, alkali bisulphate or pyrosulphate free from or containing only a little sulphuric acid is heated with the oil, as for example to 110-250 DEG  C., and may be under pressure. 0.1-0.5 per cent of acid phosphates or of nitric or nitrous acid or nitrates or nitrites may be added to accelerate the reaction.  The treated oil may be distilled under atmospheric or reduced pressure or in a current of superheated air or steam or of carbon dioxide or other inert gas, and bisulphate may be prepared by water-extracting alkali sulphate from the still residue and treating it with sulphuric acid obtained by oxidizing the sulphur dioxide evolved during the reaction.  In an example, 100 parts of crude benzine and 10-20 parts of sodium bisulphate are heated in an acid-proof autoclave to 110-150 DEG  C. for 1-2 hours under a pressure of 10 atmospheres.  In a second, 100 parts of paraffin and 10-50 parts of sodium bisulphate are stirred for 1-3 hours at 150-200 DEG  C. under a reflux condenser, and then allowed to stand; the upper layer of paraffin is readily separated when solid.  In a third, the hydrocarbon vapour is passed over small pieces of bisulphate or pyrosulphate contained in acid-resisting nets or a perforated container or in a rotary drum provided with baffles.

Filed: 1944-08-01
Abstract: 582,100. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. Aug. 1, 1944, No. 14701. Convention date, April 30, 1943. [Class 40 (v)] The amplitude modulated carrier wave in a radio receiver is converted into an equivalent train of time modulated pulses which are demodulated to produce the signal. Means are provided to translate the undulations of the carrier into a trapezoidal wave which is converted into rectangular pulses by differentiation and, by a further differentiation, into narrow pulses displaced according to the signal modulation. As shown, the amplitude modulated carrier wave 20, Fig. 3a, is clipped between limits 24, 25 to produce the trapezoidal wave 30 eliminating a large proportion of the undulations 21, 22, 23 of the carrier wave and other interfering voltage fluctuations such as 27, 28. The resulting wave 30 is passed through a differentiating circuit to produce positive and negative rectangular pulses 31a, 31b, 32a, 32b, &c., Fig. 3b, depending in width and amplitude on the width and steepness of the sloping sides of the wave 30. These pulses may first be clipped between limits 34, 35 or passed directly to a further differentiating circuit to produce pairs of positive and negative pulses such as 31ap, 31an, Fig. 3c, displaced according to the width of the corresponding rectangular pulses. The positive time-modulated pulses 31ap, 31bp, 32ap, vc. may be utilized by a final demodulator to yield the desired signal. Alternatively, a further clipping circuit using the limits 44, 45 produces the pulses of Fig. 3d for utilization by the demodulator.
