Title: Method and apparatus for feeding granular contact material into a dilute phase pneumatic lift
IPC: B01J8/00
Filed: 1955-04-15
Abstract: <PICT:0780526/III/1> <PICT:0780526/III/2> Apparatus for introducing a granular contact material, e.g. catalyst, into the lower end of a lift pipe 31, Fig. 2, comprises an annular passageway 39 at an angle of 65-85 degrees with the horizontal, lift gas inlets 46 at the base of the passageway, and inlets 38 for introducing the granular material into the passageway.  Catalyst is fed into lift tank 29, where it forms a compact bed, and flows through orifices 35 controlled by members 36 to the inlets 38.  The width of the annular passageway 39 may increase in an upward direction, and may be 1/2 to 4 inches at the point of catalyst entry; the cross-sectional area of the passageway may remain substantially constant from top to bottom and substantially equal to the cross-sectional area of the lower end of the lift pipe.  In a modification, Fig. 3 (not shown), the catalyst flow is controlled by slide valves at the bottom of the lift tank and the lift gas is fed into a horizontal chamber beneath the annular passageway and directed upwardly by means of vertical vanes in the passageway.  In another modification, Fig. 7, two annular passageways 74, 75 are provided to which catalyst is fed through conduits 83, 82 respectively from annular vessel 72.  Lift gas is supplied through pipes 79, 80, 81.  Restricting orifice plates 84, 85 are provided in conduits 82, 83 to convert compact transfer of the solids to free-fall flow.  The apparatus is suitable for use in hydrocarbon conversion processes (e.g. cracking) in which granular contact material or catalyst is gravitated as a compact mass through reaction and regeneration zones and is then pneumatically lifted from beneath the regeneration zone to above the reaction zone.  By using the apparatus described, the attrition rate of the solid material is reduced.

Abstract: 782,827. Digital electric calculating-apparatus. PLESSEY CO., Ltd. April 14, 1955 [April 14, 1954], No. 11000/54. Class 106(1). In an electronic digital parallel accumulator in which two numbers are summed by first adding together the digits in each denomination and then adding carries to obtain the final result (during a digit and a carry period, respectively) a single carry storage element for each denominational order is operable alternatively to store a carry from this order or to register a carry from a lower order when the addition of the latter carry to the count registered in the associated order would result in a carry from that order. The decimal accumulator shown comprises three denominations, with " end around carry " from the highest to the lowest (for dealing with negative numbers in the form of nines complements). During the digit period, input pulses representing digits to be summed, applied to terminals 11-13, are passed through gates G1-G3, opened by clock pulses on line L, to counters C1-3C (corresponding to hundreds, tens, units respectively). If a counter reaches " 0 " it applies a triggering output pulse to a carry store S1-S3 which then primes a gate or AND element B1-B3 connected to the gate G1-G3 of the next denomination. When a counter is set at " 9 " and a carry is stored in the previous denomination, a gate A1-A3, connected to an associated carry store, is primed. During the carry period, a carry step pulse on line M opens the primed gates and after a time sufficient to allow all the stores S1-S3 to be triggered if necessary, a, further pulse on L opens gates G1-G3 to enter the carries in the counters. A circuit diagram is given including multi-cathode counting tubes, cold-cathode triode carry stores and rectifier gates or AND elements.

Title: A new or improved method of obtaining the dispersion of a finely divided solid material in a liquid
IPC: B01J19/10
Filed: 1950-05-06
Abstract: A method of obtaining the dispersion and "wetting" of a finely divided solid pigment material in a carrier liquid with the pigment particles in a "wetted" condition resides in adding the finely divided pigment material to a carrier liquid or to a carrier liquid mixture of low viscosity and preferably of a voltaile nature or vice versa and then subjecting the liquid or liquid mixture and the finely divided additive to the influence of ultrasonic vibrations.  Finely powdered pigment is added to and/or admixed, with a relatively volatile carrier liquid of low viscosity such as white spirit or xylene.  This mixture is then subjected to ultrasonic vibrations produced by a transducer of the magneto-striction type or by a Galton whistle whereby uniform dispersion of the pigment particles is obtained.  The heat developed as a result of the ultrasonic vibrations may be utilized to evaporate part of the carrier liquid to produce a preparation having a desired solids concentration but should this heat be either insufficient or excessive then either supplemental heating may be applied or the excess heat may be dissipated.  The preparation thus obtained may be stored and used subsequently for the manufacture of paints.  The carrier may be a liquid mixture rich in a liquid of low viscosity.  The invention may also be applied to the dispersion of finely divided pigment particles in a liquid carrier for the preparation of coloured plastics. Specification 693,329 is referred to.ALSO:A method of obtaining the dispersion and "wetting" of a finely divided solid pigment material in a carrier liquid with the pigment particles in a "wetted" condition resides in adding the finely divided pigment material to a carrier liquid or to a carrier liquid mixture of low viscosity and preferably of a volatile nature or vice versa and then subjecting the liquid or liquid mixture and the finely divided additive to the influence of ultrasonic vibrations.

Title: Improvements in or relating to electric relays
IPC: H01H53/10
Filed: 1942-08-12
Abstract: 560,053. Electromagnetic relays; protective cut-out arrangements. NALDER BROS. & THOMPSON, Ltd., and LIPMAN,. C. L. Aug. 12, 1942, No. 11292. [Class 38 (v)] An electromagnetic relay is dependent for its operation on a more sensitive electrical device which may itself actuate contacts or couple a driving member to a driven member. The relay automatically resets itself when the current through the sensitive device falls below its operating value. Fig. 3 shows a form in which a primary current P energizes two secondary windings S<1>, S<2>, the winding S<1> supplying the sensitive device J as well as the operating coil 0 of the main induction type relay and the winding S<2> supplying an opposition coil R which normally overpowers the coil O. When the current reaches a certain strength, the sensitive relay J opens its contacts W, W<1> thereby breaking the circuit of the opposition coil R so that the coil 0 drives the drum M<2> which eventually operates contacts through gearing not shown. Fig. 5 shows a form in which rise of current in the primary P causes a rise of current in a secondary S<1> which feeds the sensitive device J<1> which attracts an armature E<1> causing (1) the closing of the operating circuit 0 of the induction relay M<2> and the coupling together of a pinion t and a sector T. The drum M<2> drives the pinion t and through it the sector T which eventually operates the contacts W<3>, W<4>. In other modifications, an induction motor relay is driven one way or the other according to the position of the sensitive device, Fig. 6 (not shown), the sensitive device removes the short circuit from the operating coil of an induction relay, Fig. 7 (not shown), the sensitive device responds to a current in a circuit which is closed only for a suitable direction of current, Figs. 9, 11 (not shown) or the circuit of an opposition coil is broken only when the sensitive device opens its contacts in response to overload and a directional device opens its contacts, Fig. 12 (not shown).

Title: Hydraulic tensioning control for power strapping machines
IPC: B65B13/22
Filed: 1959-04-07
Abstract: 878,839. Bundling machines. SIGNODE STEEL STRAPPING CO. April 7, 1959 [April 9, 1958], No. 11696/59. Class 94(1). [Also in Group XXIV] In a bundling machine of the kind in which a steel strip is passed round the bundle and is overlapped tensioned and sealed, means for accurately regulating the applied tension comprises a lost motion arrangement in the feed rolls drive whereby a worm gear slidable on a power driven shaft, which gear drives one of the feed rolls, is capable of moving axially against adjustable resistance when the tension reaches a certain value and thus reducing the driving effect on the rolls. The invention is described 'as incorproated in the machine forming the subject of Specification 862,471 and is the same in all respects except that of tension control. The seals used may be as described in Specification 749,926. The drive to the feed rolls is supported by a motor Fig. 1, (not shown), through a shaft 18. Fixed on the shaft 18 is a worm 194 for operating the sealing mechanism, as in the above mentioned machine, and a worm 78 which drives the feed roll shaft 44 and is axially slideable on splines 106 on a collar 108 fixed to the shaft 18. The worm 78 has a cylindrical bore 100 in which an extension 98 of the shaft 18 operates as a piston. A sealing ring 102 forms with the piston and bore an annular chamber 122, inlet to and exit from which of hydraulic fluid contained in a sump 80, is via radial apertures 124, bore 126, valve means 132, 148 and a passage 128 in the shaft extension. The valve 132 seats in the bore at 134 and permits exit from the chamber against the pressure of a spring 140. The valve 148 seats in the valve 132 and permits inlet against a light spring 158. The compression of the spring 140 is adjustable by a wheel 172 to vary the strap tension. Operation. After the strap has been fed round the bundle and overlapped, the motor is reversed so that shaft 44 is driven, clockwise as shown, to take up slack in the strap and tension it. The chamber 122 is at full capacity with the valve 132 closing-its exit. When the tension approaches the desired value, pressure rises in the chamber due to increased thrust between the worm 78 and worm'wheel 74 so that the valve 132 lifts. The worm 78 may thus move, to the left as shown, as liquid is forced from the chamber, with the result that the driving effect is reduced. Movement of the worm slides a yoke 242 on a shaft 222 permitting a shipper Figs. 2, 3, (not shown), on bearings 224 to release a spring clutch as in the earlier machine to drive the sealing mechanism. After sealing, operation of the motor reversing switch permits the worm 78 to return, the valve 148 opening to admit fluid to the chamber. When the worm is back to its original position, it again drives the shaft 44 to feed strapping round the next bundle. Specification 775,926 also is referred to.
