Patent GB-575797-A (GB)
Title: Improvements relating to the isomerisation and alkylation of hydrocarbons
IPC: C07C2/62
Filed: 1942-11-24
Abstract: In the catalytic isomerization of normal paraffins or hydrocarbon mixtures consisting mainly thereof, the feed, before passing to the isomerizer is freed from olefins and moisture by contacting with sulphuric acid, initially of not less than 98 per cent concentration, and not less than 96 per cent after absorbing the olefins.  The process is applicable to the isomerization of butane or pentane cuts with aluminium chloride, alone or on a carrier, such as bauxite, the purification preferably being effected by liquid phase counter-current flow.  The acid solution may be used for alkylating isoparaffins.  A treated butane feed, after removing acid, may be isomerized in the vapour phase at 250-350 DEG  F. and 100-400 lbs./sq. in. using aluminium chloride promoted with hydrogen chloride.  The isoparaffins produced may be fed with the used acid and additional olefines as required to an alkylation stage.  The molar ratio of isobutane to butenes is from 3 to 10 : 1, preferably 5 : 1, with a volume of acid to hydrocarbon feed of 1 : 1, a temperature of 25-80 DEG , preferably 35 DEG  F., and a time of contact of 20-200, preferably 60 mins. Butane containing isobutane, butenes, moisture and other impurities is liquefied and washed in counter-current with 98 per cent or more sulphuric acid, part of which may be recycled.  The purified feed passes through an acid separator and preheater to an isomerizer, if necessary after removal of isoparaffin.  The product is stripped of HC1, washed, and treated to separate isobutane which is fed to an alkylation stage, n-butane being recycled.  Acid containing absorbed olefins, isobutane, additional butenes and fresh acid are fed to an alkylator.  The product, after acid separation, is fractionated in stages to recover alkylate, iso- and n-butanes.  Comparative figures are given for the isomerization of untreated and acid-treated n-pentane containing pentenes which is given two batch treatments each for 1 hour with 5 per cent by volume of 98 per cent sulphuric acid prior to liquid phase isomerization with 100 per cent by weight of aluminium chloride and 22 per cent hydrogen chloride for 2 hours at 75 DEG  F. and 200-220 lbs./sq. in.  Specifications 538,307 and 553,334 are referred to.

Abstract: 1315452 Measuring current BROWN BOVERI & CO Ltd 24 May 1971 [26 May 1970] 16688/71 Heading G1U In order to amplify the signals S 1  = k 1  (1 + sin #) and S 2  = k 2  (1 + cos #) where # = # (t), and typically, as when the system is used for processing the signals that arise when measuring current in a high voltage line magneto-optically, # (t) = I sin wt, to produce signals S' 1  = k 0  (1 + sin #) and S' 2  = k 0  (1 + cos #) from which, by subtraction of k 0 , signals S 11  = k 0  sin # and S 21  = k 0  cos # may be produced, the signal S 1  is applied to a variable gain amplifier 3 controlled by a differential amplifier 1 receiving both a reference signal k 0  and a signal proportional to the d.c. level of the amplified signal S' i , this being extracted by a low pass filter TP, and the resulting signal S' i  is fed to a subtractor 11 to produce the signal S 11 , and the signal S 2  is fed to a similar loop including a variable gain amplifier 10 controlled by a differential amplifier 9. However, since the signal S 2  contains cos #, which will not in general have a zero d.c. level, (it only has a zero d. c. level if is a linear function of t), a low pass filter cannot be used to extract a value of k 2 . Instead, the signal S 2  is sampled whenever # is zero, at which instants S 2  has the value 2k 2 , and this value is compared with a reference value of 2k 0  by the differential amplifier. Sampling of the signal S 2  is effected by a sample and hold circuit 6, which is rendered operative via a gate T whenever both the signal S' 1  attains the value k 0  (which occurs when sin # = 0) and the signal S 2  is greater than k 0 , this last restiction being a convenient way of ensuring that sampling only occurs when # is an even multiple of #.

Filed: 1919-07-04
Abstract: 137,756. Siemens Bros. & Co., and Wood, H. G. July 4, 1919. Couplings combined with electric switches. An electric connexion-box, such as is used for electric cranes and other electrically-operated machines, is provided with a plug, the handle of which controls consecutively the locking in place of the plug, the setting-up of a water-tight closure, and the completion of the electric connexions. The box a has a plug c fitted with a central spindle g which forms a disconnectible continuation of the switch spindle f and carries a handle g<1> serving to control the fixing of the plug, the setting-up of the water-tight closure, and the actuation of the switch. As shown in Fig. 1, the plug comprises an upper part c' fitted with contact blades d, and a lower sleeve c<x> which is separated from the upper part by a compressible ring or gasket i and a spring h<4>, and is supported from the spindle g by three radial arms c<3>. A locking-catch h guided by stops c<4> on one of the arms c<3> is jointed to a crank h<2> upon a slidable collar h<3> turning with the spindle g, so that when the handle g<1> is turned in one direction the catch is moved out into engagement with the lower edge of the socket or opening b<3> in the box. Further movement of the handle causes a projection g<5> at the top of the spindle to ride up a cam c<5> on the plug so that the parts of the plug are drawn together, expanding the gasket to make a water-tight joint between the plug and the box. Still further movement of the handle causes the switch contacts carried by the spindle f to engage with fixed contacts disposed below the cross-plate a<1> in the box. and, in this position, to prevent unauthorized disturbance of the parts, the handle is locked by a padlock to a projection on the plug. A key and groove b<4>, c<6> are provided to ensure the proper insertion of the plug. In a modification the movable sleeve c<x> is dispensed with, and three catches h working through holes in the cap allowing a slight up-and-down movement are provided, the bulging gasket i being replaced by a washer adapted to be pressed down on to a bead or ridge on the upper edge of the mouth or socket b<3>. After the plug has been removed, the socket is closed by a lid having a movable sleeve and gasket similar to the sleeve c<x> and gasket i, the spindle g having a square at its upper end to receive a detachable key or handle; movable catches h are not provided on the lid, but the radial arms of the sleeve fit between pairs of projections on the underside of the lid. The cranks operating the catches h may be replaced by inclines or slotted cams.

Abstract: 638,782. Door latches. RUSSELL & SONS, Ltd., S., and RUSSELL, E. G. June 23, 1948, Nos. 16818 and 26342. [Class 44] In a door latch, e.g. for a motor vehicle, a wedgeshaped projection on the door or door frame cooperates with a socket member carried on the door frame or door, a spring controlled bolt extending through an aperture in the wedge or in the wall of the socket and engaging in a notch in the other member to retain the door in a closed position. The outside handle moves about a pivot not passing transversely through the door.- Fig. 1 shows the latch mechanism and Fig. 6 is an end view of the door 1 and section of the socket member 6. A sliding bolt 10 is vertically mounted in a slot in the wedge 5 and pivotally connected to a lever 11, a spring 35 urging the bolt to the shot position. The outside handle 24 is mounted on a vertical axis and has a limb 23 engaging behind a slider 19 adapted to be displaced thereby against a spring 22. A tooth 18 on the slider engages a notch 17 in a lever 16 pivotally and slidably mounted on a pin 26 and maintained by a spring 28 in engagement with the slider 19. A depending arm 15 of the lever 16 engages an arm 14 of the lever 11 and is arranged to withdraw the bolt when the outside handle is pulled. The bolt may also be withdrawn by an inside handle acting through a slider 30, an arm of which carries a hook 33 for engagement with a pin on the arm 14 of the lever 11. Movement to the left of the slider 30 therefore causes withdrawal of the bolt. If the inside handle is turned in the opposite direction to displace the slider 30 to the right, the end of the hook 33 abuts the arm 39 of a lever 36, the other arm 38 of which bears down on a pin 29 on the lever 16 and displaces it so that the tooth 18 is no longer in engagement with the notch 17. The outside handle may then move idly. The slider 30 is retained in this locked position by a spring detent 40 engaging in a notch 42. Besides the main notch 9 in the socket member, there may be provided a safety notch 45. Specification 575,277 is referred to.
