[Also in Division C5] A solvent refining process in which a lubricating oil stock introduced at 1 is contacted in packed tower 6 with a solvent introduced at 10 is controlled by a method comprising generating first, second, third, fourth and fifth signals respectively responsive to the specific gravity of the feedstock, its viscosity, its refractive index, its flash point, and the desired viscosity of the refined oil, combining these signals manually or by means of computer 50 to produce two further signals which are used to control (1) the proportion of solvent to feedstock fed to the tower; by controlling operation of flow proportioner 54, and (2) the temperature of the extract mix leaving the tower, by controlling the rate of flow of coolant through 16-17-18. In other embodiments, instead of or in addition to the cooling coil shown, the temperature gradient in the tower may be produced by introducing feed at a lower temperature than solvent, by introducing a cold reflux stream or by withdrawing a side-stream of liquid from the tower, cooling it and re-introducing it. Solvents exemplified are furfural and N-methyl-2-pyrolidone.

Abstract: 1,259,458. Protective arrangements. BRITISH RADIO CORP. Ltd. 31 July, 1969 [31 July, 1968], No. 36593/68. Heading H2K. [Also in Divisions G2-G3] A D.C. to D.C. voltage regulator of the type comprising a chopper transistor Tr2 controlled by a driver transistor Tr1 through a transformer T1 to maintain a predetermined voltage between output terminals 12, 14 is provided with a current limiting circuit to switch the transistor Tr2 off permanently or intermittently when the current therethrough exceeds a predetermined value. Regulation is effected by variation of the mark-space ratio of control pulses applied to the base of the transistor Tr1, thus providing corresponding current impulses through the transistor Tr2. A measure of each such impulse is provided by a voltage impulse derived from a Circuit C1, R1, which impulse is compared with a reference voltage provided by adjustment of the wiper of a potentiometer R2. When, during a current impulse, a predetermined . current value is reached corresponding to a predetermined relationship between the impulse and reference voltages, a silicon controlled rectifier SCR1 is triggered to turn off the transistor Tr2. By providing a suitable impedance (e.g. a diode D2) in series with the rectifier SCR1, the regulator may be arranged to operate in a current-limiting. mode, e.g. current limitation occurs if necessary during each current impulse. Alternatively a diode D1 may be provided to maintain the rectifier SCR1 conducting and so provide a trip mode of regulator operation. The transistor Tr1 may be used to turn off Tr2 upon production of an overcurrent signal. The invention may be applied to control a shunt chopper transistor.

When the vehicle ignition switch is closed, a counter gates the amplified output of a Zener diode noise generator to 7 binary counters in turn, the 7 counts being decoded and displayed for an interval determined by a preset wiper switch, after which a keyboard is illuminated and the operator is given a second interval of time determined by another preset wiper switch to enter the displayed numbers in turn on the keyboard. The numbers entered are coded, stored in shift registers and compared with the counts. If equality is obtained and the numbers were all entered within the second interval of time and no more than one key was pressed at a time, the starter circuit of the vehicle is energized.

Abstract: 1325012 Radio direction-finding DEFENCE SECRETARY OF STATE FOR 13 Sept 1971 [16 Sept 1970] 44194/70 Heading H4D Radio direction-finding apparatus for rotary wing aircraft includes a radio receiver, means for detecting a modulation of the output thereof caused by rotation of said wing, and means for indicating the strength of the modulation. As described, a helicopter 1 has a three-bladed rotary wing 1a and is fitted with an aerial 2 which is connected to a receiver 5 and which provides a figure-of-eight radiation pattern, having its null axis aligned with the longitudinal axis of the helicopter (Fig. 2, not shown). The rotation of the wing causes the radiation pattern of the aerial to oscillate, whereby a low frequency amplitude modulation is imparted to the receiver input, and consequently to its output. The effect is greatest for signals received along the null axis, and there is maximum modulation each time a rotor blade passes over the fuselage, so that with an odd number of blades the ambiguity presented by the two nulls of the figure-ofeight radiation pattern may be resolved. The rotary wing 1a is provided with an angular position transducer 6 from which a reference signal is connected to one input of a phase sensitive detector, the other input being connected to the output of the receiver 5. The output of the phase sensitive detector is connected to an indicator 7. The helicopter heading is altered until the indicator 7 gives a maximum reading, when said heading is the bearing of the source of the radio signals being received.

The valve of Fig. 2 has a lining 110 of P.T.F.E. surrounded by a moulded body 111 ; in order to eliminate cavities due to shrinkage, a filler, e.g. a cold curing silicone rubber, is injected via an adapter 112 to form an interlayer between the liner and body. In a further modification the body is moulded in two or more sections which are subsequently assembled, each section comprising a lining section.
