Title: Disazo dyestuffs
Inventor: GOTTSCHLICH ALOIS
IPC: C09B31/062
Filed: 1965-01-28
Abstract: The invention comprises disazo dyes of the general formula (I) <FORM:1091464/C4-C5/1> wherein R1 is a radical of the benzene or naphthalene series, in which the azo groups are linked in  he p-position to one another and R2 is a radical of the benzene series in which the hydroxyl group is o- or pto the azo bridge, the benzene ring A1, R1 and R2 being optionally substituted by up to three halogen atoms and/or alkyl, alkoxy or carboxylic acid alkyl ester groups, said acid alkyl ester group containing up to four carbon atoms, the dyestuffs being free from sulphonic and carboxylic acid groups. They are prepared by diazotization of the corresponding 1,3-dioxan mono-azo dye and coupling to the appropriate phenol. Coupling preferably takes place in alkaline medium in presence of an accelerator e.g. formamide, dimethyl formamide and pyridine.  The dyes give yellow, orange and red to brown shades on aromatic polyesters, cellulose acetates, polyamides polyurethanes.

Title: Improvements in and relating to alternating current electric motor systems and motors therefor
IPC: H02K47/22
Filed: 1950-02-16
Abstract: 685,140. Control of A.C. motors. GENERAL ELECTRIC CO., Ltd., and RICHARDSON, W. P. Feb. 16, 1951 [Feb. 16, 1950], No. 4018/50. Class 38 (iii) [Also in Group XXXV] Relates to systems in which a squirrel cage motor is adapted to be supplied from a single-phase source and is capable of supplying three-phase current for use by other motors or apparatus. A squirrel cage induction motor has on the stator three sets of windings arranged in three-phase relationship, two of the windings A1-A2, B1-B2, being similar, whilst the third set is divided into like sections C1-C2, C3-C4, each of which has a greater number of turns than the windings A1-A2, B1-B2. For starting (Fig. 1), all the windings are connected in series across a singlephase supply A-B, and the windings C1-C4 are shunted by a resistor R which provides the necessary phase-displacement. When the motor is running (Fig. 2), the windings A1-A2, B1-B2, are connected in series across the single-phase supply, and the sections C1-C2, C3-C4, of the third phase winding are connected in parallel. The ends C1, C3, are connected to the junction point A1, B1, and the ends C2, C4, are joined to form a terminal C which, together with the terminals A and B provides the three phase supply. The change-over from starting to running connections may be made by means responsive to the speed of the motor. In a modification two similar stator windings A1-A3, B1-B3, have centre tappings A2, B2, and the third phase winding C1-C2 has a greater number of turns than the windings A1-A3, B1-B3. For starting (Fig. 3), the winding C1-C2 is shunted by resistor R and is connected in series with the winding-sections A1-A2, B1-B2, across the single-phase supply. When up to speed the windings A1-A2, B1-B2, (Fig. 4) are connected in series across the single-phase supply and the terminal C1 is connected to the junction-point A1-B1. The ends A3, B3, C2, of the windings provide a three-phase output the phase-to-phase voltage of which is twice the voltage of the singlephase supply. Different ratios of voltage may be obtained by arranging the sections A2-A3, B2-B3, in conjunction with sections A1-A2, B1-B2, the winding C1-C2 being,proportioned to give a balanced threephase supply. Adjustable ratios of transformation may be provided by additional tappings in the three phase windings.

Abstract: 856,123. Discharge tubes. MULLARD Ltd. Feb. 9, 1959, No. 4444/59. Class 39(1). An electron beam tube comprises a single vacuum-tight envelope within which are disposed an electron-beam device, an ion pump assembly and means for forming a film of getter metal on a surface inside the envelope and adjacent the ion pump assembly. In the tube shown, the electron-beam device is a backward-wave oscillator comprising a cathode K, cathode electrode C and anode A forming an electron beam which passes along a slow-wave structure D such as an interdigital line to a collector electrode X. The output is taken through a matching section M such as a fin-line structure to a window W which is formed in a metal end-cap L and may be as described in Specification 787,925 [Group XL(b)]. The ion pump comprises a filament F and auxiliary filament S surrounded by a helical grid G. The auxiliary filament S consists of a wire of getter metal such as titanium or zirconium wound around a heating wire. Shielding discs B confine the deposition of vaporized getter metal to the region of the envelope adjacent the ion pump assembly. The filament F may be dispensed with and the heating wire utilized also to produce ionizing electrons. The getter film may be produced by any other method. The ion pump maintains a low pressure in the envelope and prevents undesirable noise modulation in the backward-wave oscillator by ionized residual gas. The invention is applicable to any electron-beam device.

Abstract: 897,542. Magnetic recording &c. loads; local circuits. THOMPSON RAMO WOOLDRIDGE Inc. Feb. 12, 1959 [June 23, 1958], No. 4964/59. Class 40 (2). [Also in Groups XIX and XL (c)] The Figure shows a circuit for writing digital information on to a channel 115 of a magnetic drum 116 in response to digital signals applied via rectifiers 214, 218 to the primary of a transformer 210 the centre tap of which is connected to a control signal. When the control signal is present diodes 214, 218 conduct so that a positive pulse from the input signal passes diode 214 and the complementary input signal which is then negative is blocked by diode 218. When the input signal is positive, terminals T1, T2 are negative and terminals T3, T4 are positive, so that transistors gates A2, A3 conduct in their emitter-collector paths while transistors A1, A4 are cut-off. Current flow takes place from supply 300 via transistors A2 through the primary winding of transformer 110 to earth 400, thus energizing write winding 111 to record a magnetic binary signal for example digit 1. When the input signal is negative transistor gates A1, A4 conduct and A2, A3 are blocked so that the current flows through the primary winding of transformer 110 in the opposite direction and head 112 is energized to record a binary digit 0. The complementary input signal may be eliminated so that diodes 214, 218 are not required and a continuous input signal is effected without a further control signal, the positive and negative portions of the signal being both effective to develop corresponding signals in the secondary of transformer 210.
