Abstract: 1,107,313. Transistor gating circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. 22 Feb., 1967 [25 July, 1966], No. 8580/67. Heading H3T. A gating circuit comprises two field effect transistors connected in series between input and output terminals with their source electrodes together, a first diode 16 connected to a source of supply, a resistive element 14 connected between the source terminals and a common connection to the gates and a twolevel control signal connected through a second diode 18 to the common connection. When the control voltage in the circuit shown is at its lower level both diodes conduct, the sources are clamped at Va and the gates have a cut-off bias applied to them. Both transistors are in the most favourable blocking direction. When the control voltage is at its higher level both diodes are blocked and the bias is removed so that the transistors may conduct. The control source is isolated by the diode and resistor 14 provides a bleed path for negative charge accumulating at the gates. This resistor may be replaced by a further field effect transistor arranged to have a high constant current type resistance when the main transistors are off and a low resistance when they are on so as to increase switching speeds.

Filed: 1949-03-30
Abstract: 660,304. Tubular posts. MASTS, Ltd. Nov. 30, 1949 [March 30, 1949], No. 8691/49. Class 20(i) A hollow tapering, tubular pole, standard or the like, has the taper of successive sections taken along at least the major portion of the length of the pole from the base thereof decreasing as the distance of the sections from the base of the pole increases. The pole may be made in one piece or may be built up from hollow truncated conical shaped units or sections made from thin sheet metal and adapted to fit one inside the other. The units may be other than circular in cross-section and can be manufactured from materials such as prestressed concrete, artificial resin or resin bonded plywood, or spun glass. A sectional pole, Figs. 1, 2, has sixteen hollow metal sections fitted together so that the taper of the sections, taken from the bottom of the pole, decreases as the height of the pole increases. The taper of the lower or base sections can be varied within limits determined by the lap joint, that is, although the taper decreases as the height of the pole increases the rate of decrease may vary. For example in a pole of sixteen sections the rate of increase of taper (starting from the top of the pole) of the four uppermost sections may increase uniformly, whereas the rate of increase of the fifth, sixth, seventh and eighth sections from the top although varying uniformly relatively to one another, might not vary at the same rate as the four uppermost sections. The thickness of each section may also be varied in order to give approximately constant stress values for the sections. In sectional metal poles the units are forced together until contact is affected over the entire area of lap joint contact. A large diameter base section 16 may be employed to give greater foundation strength.

Abstract: 1,135,287. Transistor switching circuits. ELECTRIC STORAGE BATTERY CO. 1 March, 1966 [2 March, 1965], No. 8946/66. Heading H3T. [Also in Divisions G1 and H2] A minimum voltage warning device comprises a unijunction transistor having a voltage dependent upon that to be supervised applied between its bases and a constant voltage applied to its emitter so that the transistor conducts and operates a warning device when the supervised voltage falls below a given value. When the voltage of a vehicle battery 3 drops below a value determined by a Zener diode 15 the voltage between the bases of a unijunction transistor 8 is such that the transistor conducts. A thyristor 5 accordingly conducts, lighting a lamp 14. The conduction also discharges a capacitor 10 and allows a capacitor 21 to charge. When the voltage across this capacitor is sufficient it fires a unijunction transistor 22 and discharges through its emitter junction to switch off thyristor 5. If the battery voltage is still low the cycle is repeated and the lamp flashes.

Crude liquid oxygen collecting in the base of an air rectification column 2, Fig. 1 is freed of hydrocarbons by passing it through a bundle of tubes 10 in parallel and in heat exchange with a gas, e.g. a portion of cold air branched from the inlet duct 1 of the column condensing thereon and whereby a portion of the liquid oxygen is vaporized and is discharged from the same end of the tubes 10 as is the invaporized portion in which the hydrocarbons are concentrated and from which they are removed by passage through a silica gel adsorber 18 ; the so purified liquid oxygen being returned to the base of the column 2. The mixture of hydrocarbon-containing liquid oxygen and gaseous oxygen leaving the tubes 10 is separated in a vessel 14 having a gas outlet 15 and a liquid outlet 16 leading to a pump 17. The silica gel is regenerated by flow of purifying gas e.g., nitrogen through ducts 20, 21. In a modification the partial vaporization is effected by upward flow. In a further modification crude liquid oxygen from the base of a low pressure column 55, Fig. 3, is forced by a pump 59 up the interior of tubes 61 which provides a nitrogen condenser at the head of a high pressure column 51 and the unvaporized hydrocarbon-containing oxygen from a separating chamber 67 traverses an adsorber 69 before being returned to the base of column 55 whilst part of the pure oxygen gas is discharged as product through a duct 65 and the remainder is returned through a duct 66 to the column 55.
