Title: Improvements in apparatus for distilling and fractionating liquids
IPC: C10G7/00
Filed: 1919-05-20
Abstract: 149,776. Johnson, J. Y., (Allan, H. L.). May 20, 1919. Rectifiers; film evaporators; separate heater and evaporator apparatus.-In fractionating petroleum and other liquids, the vapours from the still are passed through a series of rectifiers a, Fig. 1, connected by atmospheric condenser pipes m, and by reflux pipes b for the condensates. The rectifiers a, Fig. 3, are so constructed that the condensate entering a bottom compartment o by the reflux pipe b flows upwards through tubes c projecting into a compartment n, where the condensate is brought into contact with the vapours and is thereby. heated. The resulting vapours pass into the condenser pipes m, and the remaining liquid flows by the reflux pipe b to the next rectifier. The condensate may be further heated by means of an open steam pipe l, or while passing through an intermediate heating-compartment p.

Title: A lifting device
IPC: B66C1/32
Filed: 1951-05-30
Abstract: 707,409. Lifting devices for hoisting stacks of sheets. JAEGER MACHINE CO. May 30, 1951 [June 2, 1950], No. 12701/51. Class 78 (4) A releasable looking device prevents the normal gravity closure of the tongs of a device for lifting a pile P (Fig. 5) of sheet or plate material when the device is raised by a crane. In the device illustrated the tongs comprise loadgripping plates 32 welded at each end to the flanges of the outer vertical angle-section links 24 of parallelogram linkages 20, 22 extending from central bars 19. The spindles 23, 25, 26, 29 forming pivots of the linkages extend the full length of the device (see also Fig. 4) which is strengthened by the provision, midway between the end linkages, of links corresponding to the links 20 and 24 of the end linkages. Links 27 connected at 28 by pins working in slots in the bars 19 ensure conjoint movement of the parallelogram linkages. The device is normally held in its open condition by bars 37 (Fig. 4) secured at each end of one of the spindles 29 and formed with ratchet teeth 56 engaging the other spindle 29 and so shaped as to permit the device to expand but not to close. The bars 37 are raised by cams 41 fast On the spindle 29 and engaging a ledge 42 on the bar 37, to allow the device to close on a load, when a cable 48 anchored to a grooved sector 45 carried on a crank 46 from the spindle is pulled against the force of a counterweight 43. The cable 48 is guided over a roller 50 on the end of an arm 51 formed with a notch 54 which takes over one spindle 29 and welded to a rod 52 which slides in a block 53 secured to the other spindle 29. Compression spring devices 57 secured to the parallelogram linkages assist the automatic opening of the device when it is lowered onto a supporting surface. A stack of sheets P (Fig. 5) may be supported on the lips 34 of angle irons 33 carried by the plates 32 and provided with rollers 35 for engaging the lower surface of the stack. T-section stacking guides 62, for facilitating the positioning of one stack of sheets vertically above another, slide in housings 63 secured to one of the plates 32 and are retained in their housings by caps 64. Lugs 65 protect the upper ends of the housings 63. Stops 66 limit the extent by which the device may be lowered onto a stack.

Title: Improvements in the separation of nickel and copper
IPC: C22B15/00
Filed: 1938-04-28
Abstract: 512,347. Extracting copper. JOHNSON, G. W. (1. G. Farbenindustrie Akt.-Ges.). April 28, 1938, No. 12706. [Class 82 (i)] [Also in Group III] A process for the separation of nickel from copper contained in nickel-copper matte, by treating the said matte with copper chloride solution with the formation of nickel chloride and cuprous chloride and converting the cuprous chloride with chlorine into cupric chloride and employing the solution thus obtained for the treatment of further amounts of matte, is characterized in that the solution obtained by heating the nickel-copper matte with cupric chloride solution is divided into two parts, one part being treated with chlorine to convert the cuprous chloride to cupric chloride for treatment of further matte while the other part is treated with matte to precipitate copper. The nickel-copper matte used for cementation should preferably have a sulphur content of at the most one-third that of copper. The cementation step, which may be carried out between 90‹C. and 100‹C. may be in two stages, almost copper-exhausted matte being used for the first step and fresh matte for the second step, thus yielding almost copper-free nickel chloride solution.

Filed: 1977-03-30
Abstract: Maleic anhydride is prepared from the aqueous maleic acid solutions which originate in the vapour-phase oxidation of organic compounds having at least 4 C atoms by scrubbing the reaction gases with water by a process in which an H2O exchange is carried out between maleic acid and an organic carboxylic anhydride. The resulting organic acid can then be subjected to a suitable treatment, for example a thermal treatment, and recirculated into the dehydration step.

Abstract: 353,955. Valve generating circuits. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and REED, M., 37, Westbank, Stamford Hill, both in London. May 1, 1930, No. 13467. [Class 40 (v).] In order to avoid keyclick interference in adjacent receivers, a valve transmitter is keyed in such a way that the wave amplitude rises and falls comparatively slowly, the valve oscillator V1 being controlled by a valve V2 which is shunted across a resistance R1 in the plate supply circuit. The grid circuit of the valve V2 includes a condenser C and resistance R2 which ensure comparatively slow changes in grid voltage as the signal key K is operated. During spaces the grid is held negative by a battery B1 and resistance R3 ; whilst when the key K is closed for a mark, a battery B2 renders the grid positive. With the key K open, the valve V1 ceases to oscillate or oscillates feebly ; and closure of the key brings the valve V1 to full oscillation. The resistance R1 may be omitted.

Upward movement of the upper weight 8 is limited by girders 14 on the framework 1 and that of the lower weight 13 by contact of a rod 19 with a control switch 21. Differences in the length of the rams 16, 17 and 18 allow of the consecutive discharge of the appropriate retorts and transverse adjustment of the rams is obtained through movement of the hinged arms 22 induced by rotation of the rod 25 and worm gearing 28.

Abstract: 771,537. Measuring neutral-earth loop and earth impedance. MERITUS (BARNET), Ltd. May 9, 1955 [May 10, 1954], No. 13602/54. Class 37. Apparatus for measuring the impedance between the neutral and earth loop of an A.C. supply or other electric circuit, or the earth lead of an electric appliance, comprises terminals N, Land E for connection to an A.C. supply, a reversing switch SW1, and a push button PB for energizing a relay 12 and making a switch 11 in the circuit of an operating coil 10 of a contactor C, which contactor may operate to supply current to a magnetically shunted or " leaky field " high output current transformer T in circuit with a meter M calibrated to read directly in impedance. When testing an A.C. supply, if the apparatus is correctly connected thereto the lamp R will light and the contactor close when PB is pressed to light a lamp G. If Land N are reverse connected the lamp R will still light, but there will be no supply to the coil 12 and the lamp G will not light. Operation of switch SW1, however, will correct the Land N connections, and if the lamp G then lights it is known that cross-connection is a fault. Open N is indicated when lamp R lights only when SW1 is reversed and PB pressed, and at no other setting. Open circuit is indicated when PB is pressed and G does not light with SW1 in either position. Earth connection must then be provided. Resistance of the N.E. loop may be obtained when correct connections have been determined, by passing current from the secondary of T through the meter M, reversing switch SW2 and change-over switch SW3 back to the A.C. supply circuit and through the N.E. loop. The switch SW2 may be changed over to reverse current through the loop and obtain second and mean readings. An independent circuit is tested by changing over SW3 and passing current through fuse F to a terminal T which is connected to the neutral of the circuit to be tested, the current passing through the circuit via earth clip EC. A portable tool &c. may be earth tested by connecting its earth conductor to a socket S and terminal T, and by clipping EC to its frame. The line and neutral conductors are not connected. The apparatus passes a current of the order of 20 amps., so that if a connection is faulty, e.g. made by a single strand of a conductor, then the strand is burnt out to indicate the true condition of the circuit.
