Title: Acid catalyst separation in emulsion alkylation of olefins with isoparaffins
IPC: C07C2/62
Filed: 1957-04-30
Abstract: In the emulsion alkylation of an isoparaffin with an olefine using a liquid acid catalyst which constitutes more than 50 per cent by volume of the emulsion, emulsion is continuously withdrawn to an agitated emulsion modifying zone where sufficient hydrocarbon is added from an emulsion breaking zone in side-by-side relationship therewith to reduce the acid content to 10-30 per cent by whence <PICT:0804966/IV (b)/1> <PICT:0804966/IV (b)/2> <PICT:0804966/IV (b)/3> the emulsion passes to said non-agitated emulsion breaking zone, acid being recycled to the reaction zone and a portion of the upper hydrocarbon layer being returned to the emulsion modifying zone.  In a preferred embodiment emulsion enters the settler by inlet 31 and so enters the stirred modifying zone.  Hydrocarbon also passes into the modifying zone from the primary settling zone overflowing the adjustable weirs 42.  Modified emulsion passes to the primary settling zone by two holes 39 (Fig. 5) in front of which are two baffles 44 to minimize disturbance in the settling zone.  Deflector 45 prevents "short circuiting" of the hydrocarbon.  In the primary settling zone are baffles 41 disposed at a slight angle to the horizontal, as shown in Fig. 6. Hydrocarbon rises to the top and the acid sinks; due to the density difference hydrocarbon will flow back into the modifying zone while emulsion flows into the primary settling zone.  Acid is withdrawn by outlet 55, most being recycled to the reaction zone and some being passed through inlet 57 to the final settling zone into which hydrocarbon passes, overflowing the partition 51.  The final settling zone contains horizontal baffles 59.  Acid is withdrawn by outlet 60 and discarded, hydrocarbon overflows partition 52 into the accumulating zone and is withdrawn by outlet 61 and passed to recovery.  Unreacted isoparaffin which is recovered is recycled to the reaction zone.

Title: Improvements in or relating to ultra high frequency discriminator apparatus
IPC: H03D9/04
Filed: 1944-07-18
Abstract: 590,692. Frequency modulation. SPERRY GYROSCOPE CO., Inc. July 18, 1944, No. 13764. Convention date, April 2, 1943. [Classes 40 (iii) and 40 (v)] [Also in Group XXXV] Ultra high frequency discriminator apparatus comprises a hollow resonator having two modes of oscillation of different natural frequency and energized by an input carrier, separate detectors being fed with the respective modes of oscillation. For FM demodulation the detector output is taken to a receiving instrument, and for frequency stabilization the detector output controls a frequency-correcting device. In Fig. 1 a received FM carrier is fed byline 3 to a resonator 6 of the elliptic shape, having two modes of oscillation with the electric vector parallel respectively to the major and minor axes. These oscillations are picked up selectively by loops or probes 7, 8 and fed to oppositely-directed detectors 13. 14. The detected current flows through the resistances 15, 151 and lead 17 to the amplifier 16 feeding phones 18 or a television receiver 20. The main carrier frequency lies between the two natural frequencies of the servomotor and as it moves towards either of them the voltage at 17 moves to one or other direction from zero. The resonator may alternatively be of cylindrical form with its natural frequencies adjusted by plungers (Fig. 4, not shown), a rod lying along the axis of the resonator prevents the setting up of oscillations of undesired modes. Fig. 8 shows a frequency stabilizing arrangement for the oscillator 29, which feeds part of its output to a double-frequency resonator 6' with two pick-ups 7<1>, 8<1> feeding detectors 33, 33'. The output is taken in push-pull to valves 37, 37<1> which control a'motor 39 for correcting the oscillator frequency through gearing 40 and plungers 41. In Fig. 9 the oscillator 29<1> feeds the resonator 42 and the pick-ups 50 supply detectors 44, 44<1> in the form of currentvariable resistances. These are connected as adjacent arms of a bridge with resistances 52 connected as the opposite arms. Alternating current is supplied. from 47, 48 to one bridge diagonal, and output is taken from the. other diagonal to an amplifier 53 and transformer 54. The source 47 is connected through transformer 55 to rectifiers 56, 56<1> with load resistances 57, 57<1> while the bridge output is supplied to a centre tap on the secondary 55 so as to unbalance the voltage across the resistances 57, 57<1>. This unbalance voltage is fed through smoothers 58 to the grid of a valve 60 lying in the supply lead to the cathode 61<1> of the oscillator 29<1>, thus correcting the frequency. The crystal detectors used in Figs. 1 and 8 may comprise a crystal and wire contact unit 21, Fig. 7, connected at one end to the pick-up loop 7 and having a capacity coupling to the casing 10. The circuit for rectified current is completed through a spring 22 and the inner conductor 9 of a coaxial line. Specification 523,712 and U.S.A. Specification 2,227,372 are referred to.

Filed: 1956-05-04
Abstract: 834,240. View-finders. AGFA A.G. May 4, 1956 [May 7, 1955], No. 13928/56. Class 98(1) In a view-finder for a photographic camera having interchangeable objectives, two relatively rotatable plates are provided with perforations so arranged that, by relative rotations of the plyates, different sets or different parts of the same set of perforations are brought into registration and thus define a field of view different for each objective. The successive fields of view may be defined continuously by a set of perforations in the form of slots 22, 23, the 'intersections 25 moving diagonally along stationary slots 23 as plate 6 is rotated. In a view-finder combined with a rangefinder L-shaped perforations are arranged on a non-rotatable plate 2 to define a nesting series of rectangles and on a rotatable plate 6 to define rectangles at different orientations so that only one set of four pairs of perforations register at any one time. The transverse movement of lens 19 which varies the adjustment of the rangefinder also moves the plate 2 by means of lever 14 to compensate for parallax at short range. Aperture 20 of collar 5 forming a bearing for the rotatable plate 6 admits the comparison image of the rangefinder, the two plates 2, 6 being arranged at the focal plane of eye-piece 16 and half silvered and fully silvered mirrors 17 and 18 respectively being provided. The change from one field of view to another may be effected by hand or by a rearwardly extending pin on each objective.

[Also in Group XXX] Substantially uni-directional vibrations are imparted to a conveyer tube 1 by a pair of exciters 4, 5 fixed relatively to each other and having oppositely-rotating off-centre weights which are separately driven, the exciters being mounted so as to be able to vibrate in a plane containing their parallel axes for a short time until synchronism is automatically established solely by the inertia forces, thus avoiding the need for mechanical or electrical coupling between the two exciters. As shown, the tube 1 is supported on inclined lath springs 2 and the exciters 4, 5 are carried by a leaf-spring 6 augmented by a spring 8. In modifications the two exciters are rigidly attached to the tube or other member to be vibrated and the latter is supported on helical or other springs allowing both movements in the disired direction and transverse movements which persist until synchronism is established. In a construction providing for reversal of conveying a tube 41, Fig. 5, is vibrated by a pair of off-centre exciters 42, 43 to convey in direction B, and by a pair of exciters 44, 43 to convey in direction A. The exciters are mounted adjacent the centre of gravity of the tube. The exciter 43 is separately driven, while the exciters 42, 44 may have separate driving motors or a common motor selectively coupled to one or other exciter, according to the desired direction of conveying. In another construction a conveyer tube is vibrated elliptically by two oppositely-rotating off-centre exciters of different size and the conveying direction is reversed by reversing both exciters.
