Title: Process and apparatus for dispersing or dissolving a substance in a liquid
IPC: B01J19/24
Filed: 1951-10-11
Abstract: <PICT:0708355/III/1> <PICT:0708355/III/2> <PICT:0708355/III/3> Solid, liquid or gaseous material or a mixture of two or more such materials are brought into intimate contact or solution in a liquid by forcing the latter liquid through a vortex chamber to form a liquid vortex having a low pressure hollow core around which the liquid leaves the chamber through an axial discharge aperture and introducing the first mentioned material or mixture of materials continuously into the hollow core so that dispersion or mixing takes place under the action of the rotary vortex current.  In Fig. 1, liquid under pressure is supplied along a tangential feed pipe 1 into a rotation chamber 7, where it forms a rotating liquid body.  An aspirating pipe 8 projects axially into the chamber 7 and the material to be dispersed in or mixed with the liquid is aspirated through the pipe 8 by a hollow core of low pressure formed along the axis of the rotating liquid body, mixture or dispersion being effected by the action of the rotary liquid current and the centrifugal forces obtaining in the vortex. The dispersion or mixture leaves the chamber 7 through an axial discharge aperture 3.  The embodiment of Fig. 2 is specially suitable for mixing or dispersing in a liquid, material having a higher specific gravity than the liquid.  The tangential feed pipe 1a and axial discharge aperture 3a are provided at the same end of the chamber 7a so that the larger particles of the added material are centrifuged away from the outlet 3a and are re-cycled.  The apparatus of Fig. 3a is specially suited for use with its discharge aperture 23 below the level of a liquid.  The pressure liquid is supplied first to a chamber 16 from which it enters the rotation chamber 11 through a number of tangential slots 13.  The position of aspirating pipe 19 can be adjusted vertically and the supply of aspirated material can be controlled by means of a valve 24.  In each of two further embodiments, Figs. 5a, 5b and 6a, 6b (not shown), several rotation chambers formed in a single block are combined to form a multi-chamber apparatus.  In another embodiment, Figs. 4a, 4b (not shown), finely divided solid materials or liquid materials of high viscosity are fed along the aspirating pipe by a screw conveyer in the pipe and two liquid components are separately introduced through separate tangential feed pipes.  The invention is applicable to purifying a liquid or a gas by dispersing it in a liquid; aerating waste water, slime suspensions or other liquids in which aerobic micro-biological processes take place as for example in the preparation of alcohol, acetic acid and various bactericides, or performing heterogeneous catalytic reactions in a liquid medium where the catalyst is finely divided in the liquid phase.

Title: Control systems for electric motors
IPC: H02H7/085
Filed: 1948-09-09
Abstract: 652,188. Control of two motors. BRITISH CELANESE, Ltd. Sept. 9, 1948, No. 23758. Convention date. Sept. 9, 1947. [Class 38(iii)] Control apparatus for use with a plurality of electric motors individually driving devices adapted to perform related operations, comprises an element responsive to changes in current supplied to one of said motors, a timing device adapted to be set in operation upon said element responding to an increase in said current to a predetermined value above normal and to be reset on said element responding to a return of said current to normal, and means for disconnecting the supply of power to a second such motor without interrupting the supply of power to the first-mentioned motor, said means being arranged to be operated by said timing device after the elapse of a set period during which the current supplied to the first-mentioned motor remains above said predetermined value. The Figure relates to a system for a pulverizing mill having a hammer mill motor M1 and a feed screw motor M2. When an overload occurs on the motor M1 an inductive coil 3, which is linked with one of the supplylines to the motor, becomes effective to disturb the balance of opposing primary windings 9, 11, of transformer 4. The winding 9 is connected across winding 3, winding 11 being supplied with a reference voltage from secondary winding 6 of mains-connected transformer 7. If the degree of substance is sufficient, a section 14a of a double triode valve becomes effective to energize a relay-coil 21 and open contacts 31, 32, thereby removing high negative potentials, derived through rectifier valve 34 and transformer secondary winding 36, which are applied to the grids of valve-sections 33a, 33b. Upon opening of contact 32, a condenser 37 commences to discharge through resistors 38, 39, and, after a predetermined short time interval section 33a passes sufficient anode current to energize relay-coil 43. If the overload on motor M1 has persisted during this period, contacts 54, 55 open the power circuit to motor M2 and no additional material is fed thereby to the mill. Opening of contact 31 causes condensers 47, 48 to discharge through resistors 45, 46, and, if the overload on motor M1 persists for a predetermined period after the motor M2 has been stopped, contacts 66, 67, of relay 49, become effective to disconnect the motor M1. If the duration of the overload on the motor M1 is such that the feed motor has been disconnected but the mill motor has not, then, provided the mill motor current returns to its no-load value, contacts 77, 78 close to re-energize the feed motor M2. This is effected by the primary winding 11 overcoming the winding 9 to render valvesection 14b operative to energize relaycoil 29. The sensitive device 2 may be responsive to rate of change of mill motor current and/or predetermined value of current. Apart from indicating the magnitude of current, a suitably connected set of coils, similar to the pick-up coil 3, may be used to obtain a signal proportional to the unbalance of current in a polyphase power system.

Abstract: 1,060,262. Transistor amplifiers. MINISTER OF AVIATION. June 3, 1965 [June 11, 1964], No. 24342/64. Heading H3T. A transistor amplifier with reduced crossover distortion and temperature drift comprises PNP and NPN- emitter-followers Q3 and Q1 (Fig. 2) with a common input to their bases, emitter-coupled respectively to the bases of further NPN and PNP transistors Q4 and Q2 having a common emitter load R7. By including switches S1 and S2 (which may be further transistors) the amplifier may be used as a high-impedance switching circuit when all four transistors are cut off simultaneously. In this case diodes may be joined in series with the switches and also in series with the emitters of the input transistors to prevent breakdown of the emitter-base junctions when reversedbiased. Each individual transistor may be replaced by a Darlington pair. Fig. 1 (not shown) describes a transistor amplifier not forming part of the invention. This amplifier comprises an NPN emitter-follower feeding a common-emitter PNP stage, the base of the NPN and the emitter of the PNP being connected to potentiometers across the power supply. The centre tap of the latter is earthed and the NPN collector is joined to this point by a Zener diode.

Abstract: 628,204. Locks; latches. KORESKA, R. J. Sept. 8, 1947, No. 24678. Convention date, Sept. 7, 1946. [Class 44] In a door lock of the type in which a bolt 1 adapted to be retracted by means of a handle which can cooperate with the bolt through the medium of a coupling member 15, mounted on a keyoperated displaceable member 6 such that the coupling member 15 in one position of the key-operated member 6 is in an operative position and in another position of the key-operated member is in an inoperative position, the key-operated member is provided with a barring member 19, which when the key-operated member is moved to make the coupling member inoperative is adapted to engage the bolt 1 to lock it in its projected position. The bolt 1 projected by a spring 5 is normally retracted by a handle connected to the spindle 17. When the spindle 17 is rotated clockwise the follower 16 engages one arm of a lever 15, the other arm of which abuts a projection 22 on the bolt to withdraw it. The lever 15 is mounted on a slide 6 which is guided by pins 4, 9, entering slots 8, 7, respectively. By inserting a key in keyhole 14 and rotating anticlockwise so that the keybit engages the recess 13, the slide 6 may be lowered. This disengages the lever 15 from the follower 16, rendering the handle idle and the pivot pin 19 of lever 15 enters a slot 20 in the bolt to block the latter in the projected position, the bolt being formed with two slots 20 to render it reversible for right- and left-hand doors. A ball 12 mounted on a spring 12a engages one of the notches 10, 11 in the slide 6 to retain the latter in one of its limiting positions. A modification is described in which the barring member is a separate projection on the slide, which enters a recess in the bolt so that the lever 15 may be mounted anywhere on the slide. In further modifications tumblers may be provided for co-operating with the key and slide 6 or a cylinder lock may be employed. The lever may also be made single-armed.
