Title: Improvements in or relating to a method for separating low boiling tar acids from a mixture with low boiling neutral oils
IPC: C10C1/18
Filed: 1954-11-18
Abstract: Tar acids are separated from a mixture with neutral oils by separating the mixture by distillation into a lower-boiling fraction having an end boiling-point of 180 DEG  to 210 DEG  C. and containing substantially all the phenol and some cresol and a higher-boiling fraction having an initial boiling-point of 180 DEG  to 210 DEG  C. and containing cresol but substantially no phenol, the former being subjected to continuous countercurrent double solvent extraction using paraffinic naphtha having a density of less than 0.8 and 40-55 weight per cent aqueous methanol, and the latter being subjected to a similar extraction using paraffinic naphtha having a density of less than 0.8 and 55-75 weight per cent aqueous methanol, tar acids being dissolved by the aqueous methanol and neutral oils by the paraffinic naphtha. The methanol extracts may then be separately distilled to recover the purified tar acid fractions or the extracts may be combined, the methanol removed and the tar acid fractionated to yield individual tar acid fractions.  In a modification of the invention, the methanol extract of the lower-boiling fraction is passed over anion exchange material to remove carboxylic acids as described in Specification 718,467, the methanol extract of the higher-boiling fraction is then added and the combined extracts are passed over cation exchange material to remove tar bases as described in Specification 741,651, [Group VI], before removal of the aqueous methanol and fractionation of the tar acids.  The tar acids may contain phenol, cresols, xylenols and higher-boiling phenols such as ethyl phenol and trimethyl phenols.  The process may be applied to tar acid oils boiling between 160 DEG  and 300 DEG  C. and containing tar acids, neutral oils, tar bases and carboxylic acids.  The tar acid oils may be derived from tars produced by the low-temperature carbonization of bituminous coal.  A further modification relates to the refinining of tar acid oils boiling between 160 DEG  and 240 DEG C. by distilling the oil to obtain two fractions boiling in the ranges 160 DEG  to 200 DEG  C. and 180 DEG  to 240 DEG  C. respectively, subjecting the fractions to double solvent extraction in accordance with the invention and subjecting the methanol extracts obtained to the ion exchange treatment described above.  The purification of a tar acid oil of boiling range 160 DEG  to 240 DEG C. by the process of the invention is described, the oil being distilled into two fractions of boiling range 160 DEG  to 190 DEG  C. and 190 DEG  to 240 DEG  C. respectively.  A paraffinic naphtha boiling between 60 DEG  and 130 DEG  C. is used in the extractions and the methanol extracts are subjected to the ion exchange treatment mentioned above.  U.S.A. Specification 2,666,796 also is referred to.

Abstract: 527,626. Impedance networks; valve circuits. MAGUIRE, I. L. Nov. 21, 1938, No. 33835. Convention date, Nov. 26, 1937. [Classes 40 (iii) and 40 (v)] Wide-band amplifiers are rid of distortion, due to inter-electrode feedback, by the use of input, intervalve, and output networks of constant impedance and comprising resistances which reduce the energy feed-back. Each network may comprise a resistance R and condenser C, Fig. 8 (and Fig. 3, not shown) in parallel with resistances r<SP>1</SP>, r<SP>2</SP> and inductances l<SP>1</SP>, l<SP>2</SP> where (r<SP>1</SP> + r<SP>2</SP>)= R, (l<SP>1</SP> + l<SP>2</SP>) = CR2, and r<SP>1</SP>/r<SP>2</SP> = l<SP>1</SP>/l<SP>2</SP>. Then the impedance between the output terminals A, D is a constant resistance equal to R, and that between the output terminals B, D is a constant real fraction of R. The resistance r<SP>2</SP> may be the grid leak resistance as shown. Other forms of network are shown in Figs: 5, 6, 7 where the condensers C<SP>6</SP>, C<SP>7</SP>, C<SP>1</SP>, C<SP>2</SP>, C<SP>8</SP> are blocking condensers to prevent d.c. coupling ; and the inductances l<SP>1</SP>, l<SP>2</SP> may be interchanged with the capacitances C, as in the circuit 5, Fig. 8 (and Fig. 4, not shown), the circuits 4, 5 being associated with the grids and the anodes respectively of the valves. Valve circuits embodying these networks as grid-leaks (as at 4, Fig. 8) or anode loads (as at 5) are illustrated in Figs. 5a, 9, (not shown) and push-pull valve circuits of the same kind in Figs. 10, 11 (not shown), while Figs, 12, 13, 14 (not shown) illustrate the manner in which the invention reduces the undesired feedback. Mutual inductance may be used instead of self-inductances.

Title: Improvements relating to locking and interlocking arrangements for electric circuit closing devices
IPC: G11B15/02
Filed: 1930-11-11
Abstract: 366,607. Keyboard switches. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 64, Heathwood Gardens, Charlton, both in London. Nov. 11, 1930, No. 33915. [Class 38 (v).] Interlocked switches.-An arrangement of interlocked key switches for use in signalling &c. systems combines an interlock of the chain or like nature whereby the depression of two keys simultaneously is prevented with a spring- controlled locking plate operative on the depression of any key to prevent the depression of any other key of the series, the locking plate being latched in its displaced position to retain the operated key depressed. The latching detent may be released by an associated electromagnet. As shown in Fig. 1, the keys 1 are mounted on operating rods 2 formed with extensions 4 adapted to co-operate with balls 42 and dumbbell-like spacers 42a so disposed within a tube 41 that on depression of any key the members 42, 42a are forced into close formation so preventing the depression of any other key. The operating rod 2 of each of the key switches has a lateral screw 12 extending into an acute-angled slot 11 formed in a sliding locking-plate 17, the action of the screw 12 on the lower portion of the slot 11 moving the plate 17 to the right against a return spring and causing it to be automatically latched in its displaced position by a pivoted spring- controlled detent 28 engaging a recess in the locking plate. Thus the operated key is retained in its depressed position and the unoperated keys are held positively from operation until the detent 28 is released by an extension 37 of the pivoted armature of a releasing electromagnet 34. Each of the keys, Fig. 3, carries an insulating coned member 3 for operating spring contact sets 15 at one or both sides of the spindle through rollers 16 carried by the movable contact springs and the lower portions 4 of the operating spindles are surrounded by springs 6 for retracting the key switches on their release. Further contact springs such as 45 may be operated by insulating projections attached to the latching detent 28 and to the locking bar 17.

Title: Improved means for guiding a missile
Inventor: HALTON CHARLES CHRISTOPHER
IPC: F41G7/22
Filed: 1961-09-22
Abstract: 1,031,393. Televising from vehicle. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. Sept. 12, 1962 [Sept. 22, 1961], No. 34109/61. Heading H4F. [Also in Divisions F3 and G3] A guided missile includes a television camera head, means for angularly adjusting the sight line of the camera head relative to the missile structure, and means responsive to sight-line control signals to operate the means for adjusting the sight-line thereby altering the field of view of the camera head. As shown in Fig. 1, a television camera 4 having a Zoom lens 6 is connected to the structure 10 of a roll-stabilized missile by gimbals 8, servo motors 12, 14 enabling the camera to be moved in the pitching and yawing plane, respectively. A camera control receiver 16 receives through antenna 18 signals from a control transmitter 20 in an aircraft from which the missile is launched. These signals, representing the required pitching and yawing movements of the camera, are applied through amplifiers 22, 24 to a torque motor unit 26 associated with a gyro in a " bootstrap " gyro system rigid with the camera. The unit 26 has four angularly spaced poles co-operating across a narrow gap with a disc mounted on the inner gimbal ring and coaxial with the gyro spin axis. A pick-off unit 30 similarly has four poles cooperating with another disc mounted on the inner gimbal ring. Signals from amplifier 22 energize one pair of poles of the unit 26 resulting in angular movement of the gyro rotor axis and the generation of pitch-demand signals in the corresponding pair of poles of the unit 30. Similarly, signals from amplifier 24 cause yawdemand signals to be generated by the unit 30. The signals from unit 30 are applied to servos 12, 14 through conductors 32, 34. Pick-offs 40, 42 associated with the gimbals feed signals to the electronic system 44 of an autopilot and control surface actuator 46. The camera output 4 is applied to a missile transmitter 48 and received by a receiver 50 on the aircraft. In use, the operator on the aircraft rotates the sight line in the missile as required and when the sight line has been located the Zoom lens 6 is controlled by a unit 51 to provide amplification of a much smaller area. The sight line is kept pointing at the target and the missile is steered in the direction of the sight line whereby the target is intercepted. In a modification (Fig. 2, not shown), in which the missile is not, roll-stabilized, the camera is mounted for freedom of movement about three axes and a vertical gyro is provided for roll-stabilizing the camera. In another embodiment (Fig. 3, not shown), the television camera is fixed with respect to the missile and the Zoom lens is optically associated with a mirror system which is roll-stabilized but has freedom in pitch and yaw to respond to signals from the operator.
