Patent GB-664095-A (GB)
Title: Improvements in and relating to alkylation products
IPC: C10G50/02
Filed: 1949-05-20
Abstract: Aromatic hydrocarbons contained in a kerosine are alkylated with less than the molecular equivalent of one or more C6 to C12 olefines in the presence of a Friedel-Crafts' catalyst. The kerosine must contain only aromatic hydrocarbons having not more than 3-alkyl substituents for each aromatic nucleus.  It may be reacted as such or the aromatics extracted, as with sulphur dioxide.  Extracts boiling between 210 DEG  and 260 DEG  C. are suitable for alkylation with C6 to C9 olefins which may be a fraction of a cracking product of paraffins.  The molar ratio of aromatics to olefins is suitably 4 : 1.  Aluminium chloride in an amount of 0.5-10 per cent by weight is the preferred catalyst. Reaction is effected at about 20-100 DEG , preferably 40 DEG  C., generally in about 3-6 hours.  The products are suitable for transformer oils, having a negative gassing coefficient, for concondenser, hollow cable, and switch oils.

Title: Improvements in coil formers for electrical induction apparatus
IPC: H01F5/02
Filed: 1962-04-09
Abstract: 947,012. Transformers. GENERAL ELECTRIC CO. April 9, 1962 [April 28, 1961], No. 13525/62. Heading H1T. A coil spool 16 of non-cellulosic insulating material is formed in two or more axially separated sections 28, 29 (Fig. 3), the adjacent edges of which define a circumferential gap which is of undulating shape to provide support for the coils without allowing turns to enter the gap. Construction of the spools in this manner reduces the danger of voids and gas pockets which lead to early insulation breakdown. Fig. 3 shows an exploded view of three nested coil spools, the inner 15 being of unitary construction to support a low voltage winding and 16, 17 being spools constructed according to the invention to support high voltage and low voltage windings respectively. The shields 21 insulate the outer winding from wound core 1 (Fig. 1) and also hold the spools in position. Member 28 has integral flange 30 which is stepped to form radial ducts 31 and the high voltage winding may be pre-formed in two sections which are connected in series and of sufficient width to separate the sections 28, 29 and provide gaps 32. Gap 39 in the outer spool is maintained by contact at two points 38. The elongated oval cross-section ensures a high space factor where the core is situated at the minor axis and good oil circulation and lead space at the major axis. The two low voltage coils may each have two layers and be interconnected so that the inner layer on one coil is in series with the inner layer of the other to form one low voltage section and similarly the two outer layers are in series to form the second. In addition to the normal enamel insulation on the conductors of the low voltage coils, sheets of flexible semi-cured resin-filled glass cloth may be inserted between layers. The transformer may be enclosed in an oil-filled tank or may be encapsulated in epoxy resin.

Abstract: 1,153,270. Bi-stable circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 22 March, 1968 [25 March, 1967], No. 13881/68. Heading H3T. In a bi-stable circuit comprising two crosscoupled transistors of one conductivity type with a common emitter resistance, each transistor is connected anti-parallel with another transistor of opposite conductivity type, the bases of the latter transistors being connected together and receiving the input signal, thereby steering it to the appropriate transistor of the bi-stable pair. In Fig. 2, if transistor 1 is conductive and transistor 2 is cut-off, an input signal 6, through capacitor 16, applied to the base of control transistor 13, causes it to conduct, thus increasing the voltage drop across resistor 11 and decreasing that across resistor 10. By a cumulative effect, transistor 2 becomes conductive and transistor 1 is cut-off, with control transistor 12 held at the limit of the pass region by the value chosen for resistor 15 of the voltage divider shown as resistor 15 and 14. In Fig. 3 (not shown), the collector of transistor 13 is taken to a reference potential through a resistor 17 across which an output signal of half the input frequency can be obtained.

[Also in Division G4] An electronic device, such as a digital computer, is energized by direct current and has means for monitoring the energy supply level and responsive to the attainment by the level of a predetermined value within the energy level limits within which the device operates reliably to cause circuits in the device to effect predetermined operations before the energy supply reaches one of said limits. Assuming a potential decay of the - 15-volt supply from the correct 100% value, action is initiated when the level has fallen to 91% of the value. The potential being monitored is connected via a voltage divider network 28 to a trigger circuit 34 and when the 91 % threshold value is reached, the trigger circuit 34 is operated thereby cutting off conduction through a Zener diode 46 to allow the - 15-volt potential applied at a terminal 56 to cause a transistor 52 to conduct thereby in sequence (1) causing a signal to disable the memory reference circuits; (2) operating a switch to disable the power supply of the memory, and (3) causing other corrective action to take place. These actions are completed before the operating potential has fallen to the 90% level below which the computer operation is unreliable.

A transistor switching circuit comprises two series connected transistors to the base of one a controlling voltage is applied and the base of the other is connected to a constant voltage source the base voltage of this transistor being prevented from exceeding a safe predetermined level. Fig. 2 shows a circuit for switching a voltage U3 of - 160 volts to a load R L  comprising two series connected switching transistors T2, T3. The switching control voltage U 1  is applied via transistor T 1  so that transistor T2 conducts only when transistor T 1  is rendered non-conductive by the control voltage. The conduction of transistor T 2  causes base current to flow in transistor T 3  which therefore conducts so that current is switched through the load R L . 'With the values of voltages shown in Fig. 2 the base potential of transistor T 3  when transistor T 2  is blocked is limited to +5 volts. In the modification shown in Fig. 3 when transistor T 3  is blocked the path through resistor R6 from the base of T 3  is blocked since diode D1 is cut off. When via transistor T 1 , transistor T 2  and thus transistor T 3  are caused to conduct the voltage at the emitter of transistor T 3  changes from - 80 to 0 volts so that diode D 1  conducts and transistor T 3  is also conducting. The voltage at the base of transistor T 3  is determined by the voltage divider R 9 , R 10  and is limited with the values shown to approximately + 6 volts.
