Abstract: 1,255,684. Automatic voltage control. KOMBINAT VEB FAHRZEUGELEKTRIK RUHLA. Aug.4, 1969, No.38935/69. Heading G3R. In a vehicle supply system comprising an A. C. generator 1 charging a battery 4 and having its field winding 5 controlled by a conventionallyoperating vibratory-contact voltage regulator 6, the vibrating contact 9 is controlled by a winding having two parts 7 and 8 respectively responsive to the battery voltage and the generator voltage. The part 7 is dimensioned so that even at maximum battery voltage it will not open the contacts 9, 10 corresponding to the fully energized condition of the winding 5. Thus the regulator will only operate with a voltage present on the (aiding) part 8 which produces normal vibratory action of the contact 9 in accordance with generator voltage vibrations. The described arrangement prevents misleading operation of a lamp 15 controlled by a relay 13, 14 responsive to the generator voltage, such operation occurring in known arrangements wherein the regulator has a single winding connected directly to the battery. The part 8 may be connected between other points in the system providing a D. C. supply, or other points providing an A. C. supply in which case further rectifiers are required.

Abstract: 1,014,767. Endless conveyers; load engaging devices. E. P. REMY & CIE. Oct. 22, 1962 [Nov. 7, 1961 (2)], No. 39860/62. Heading B8A. An apparatus adapted to properly arrange bottles B &c. on a conveyer belt 2a or 2b to permit subsequent gripping, comprises a grouping device 1a disposed upstream of a distributing device 23a (Fig. 5), the devices being driven simultaneously with and in the same direction as the belt and at a lower velocity, and being provided with stop members 9 and 29 adapted to co-operate with the bottles B. Each of two grouping devices la, 1b (Fig. 1) on opposite sides of the conveyers 2a, 2b comprises an endless chain 3 in the horizontal plane driven by a pair of sprockets 4, 5 mounted on a rigid frame. A plurality of supports 8 secured to the chain 3 at selectively spaced intervals, each carry a pivotally mounted stop member 9 normally urged by a spring 11 into a position inclined to the chain 3. A roller 12 on each support 8 engages a rigid guide member 13 along the operative portion of the chain path adjacent to the belt. In operation, one of the stop members 9 is engaged by a bottle and is pushed into a position at right angles to the direction of travel, whereupon the bottle velocity is retarded and the following bottles contact one another. The following stop member divides the contacting bottles into separate groups. As the first stop member is retracted from the path of the bottles, the first group is conveyed by the belt to the distributing device 23a. Each of two distributing devices 23a, 23b (Fig. 5), is similar to the grouping device but the supports 28 incorporate pins 29 slidably mounted in sockets 30 and selectively spaced to allow one bottle B between any two pins which are disposed at right angles to the chain. A roller integral with each pin 29 engages guide members 33a, 33b which cause the pins to be ejected from their sockets on the operative portion of the chain path and otherwise receded. A first pin 29a of the series is fixed in the ejected position and engages the first bottle of the group while the following bottles are spaced from each other by the ejected pins 29. In further embodiments of both the grouping and distributing devices (Figs. 3, 4, 7, 8, not shown) the endless chain is disposed in a vertical plane and underlies the conveyer. The stop members consist of rods slidable in supports rigid with the chain links. Rollers on the inner ends of the rods engage guide members which cause the rods to be ejected up through the supports and through the belt, on the operative portion of the chain path. These devices may be arranged between adjacent conveyer belts for simultaneous spacing of two or more rows of bottles.

Title: Improvements in process and apparatus for cooling and removing condensables from gases
IPC: B01D51/10
Filed: 1959-11-25
Abstract: <PICT:0874866/IV (b)/1> A process for cooling and concurrently removing condensible impurities from a warm product inlet gas particularly in the cooling and cleaning of the product gases such as acetylene containing gases in a hydrocarbon cracking system by the removal of water, oils, tars and solid carbon particles therefrom comprises passing the gas through a relatively cool pebble-packed regenerative zone and in so doing cooling the gas below the saturation temperature of impurities therein and depositing such impurities in the zone, and thereafter passing a relatively cool gas through the zone to cool the latter and to evaporate the deposited impurities and cycling the pebbles through the regenerative zone at a rate sufficient only to maintain the regenerative zone in a substantially impurityfree condition. Suitable pebble materials mentioned are alumina, metals, natural sand, and gravel.  The pebbles may have adsorptive or catalytic characteristics.  Only apparatus concerned with the cooling and cleaning of air prior to its separation in a rectification column is described and Fig. 2 shows such apparatus employing two regenerators 112a and 112b.  Process air is introduced through a conduit 118 and is directed into the warm end 115a or 115b of one or other of the regenerators in which it flows downwardly through the pebble bed to the cold end 114a or 114b for cooling and deposition in the pebbles of carbon dioxide and other condensibles, the cooled and cleaned air passing ultimately through a check valve 121a or 121b to a conduit 120 leading to the rectification column (not shown).  Cold purge gas which may be one of the air constituents from the column is meanwhile passing through the other regenerator to a conduit 116.  Slow cycling by means of an elevator 125 of all the pebbles 113 through the warmer zones of the regenerators is said to ensure removal of all the condensibles not removed by the purge gas.  In the form shown normal heat inleak from the atmosphere to the pebbles in elevator 125 is said to be sufficient to evaporate deposits such as carbon dioxide but in other applications heating means may be provided to ensure cleansing of the pebbles.  The withdrawn pebbles may be recooled to remove sensible heat abstracted from the relatively warm product gas.  In a further form (Fig. 3 not shown) applicable to an air separation system, regenerators are arranged in pairs with the cold end of one regenerator adjacent the cold end of the other regenerator.  This arrangement it is said avoids the refrigeration loss which occurs as the result of removing the pebbles from one end of the regenerator and adding them to the other end.
Patent GB-908011-A (GB)
Title: Process for the separation of isophthalic and terephthalic acids
IPC: C07C51/43
Filed: 1958-12-11
Abstract: Isophthalic and terephthalic acid are separated from mixtures containing them by forming a solution of them, supersaturating the solution with respect to one of these acids by controlled cooling or concentration so that nucleation is established without substantial precipitation of crystals from the solution, thereafter cooling or concentrating the solution to precipitate the acids as a crystalline mass, and separating from this mass a relatively large-crystal fraction enriched in the nucleated acid, and a relatively small-crystal fraction enriched in the other acid.  Preferably the solution is supersaturated with establishment of nucleation by controlled cooling at a slow rate and the subsequent crystallisation is effected by cooling at a relatively rapid rate.  The solvent may be water, methanol, ethanol, acetic acid, dimethyl formamide, or dimethyl sulphoxide. The iso- and tere-phthalic acids may be dissolved in hot water under super-atmospheric pressure and the nucleation and crystallisation steps may be effected by evaporatively cooling the solution by reduction in pressure.  The treatment may be applied to a mixture of phthalic acids obtained by oxidation of a mixture of xylenes, or other alkyl benzenes or intermediate oxidation products thereof.  Such acid mixture may be subjected to solvent extraction to remove orthophthalic acid, and the residue consisting of a mixture of iso- and tere-phthalic acids containing terephthalic acid in excess of that corresponding to the constant solute ratio may be leached with a solvent to form the solution for the separation treatment, leaving a solid residue of terephthalic acid.  In an example, water is used as the solvent.  A solution of the mixed acids is prepared in an autoclave at 337 DEG F. and is concentrated to effect supersaturation by evaporative cooling.  The temperature is lowered slowly to 327 DEG F. and then over a period of 2 hours to 300 DEG F.  It is then lowered more rapidly by reducing the pressure to atmospheric pressure over a period of 1/2 to 1 hour.  The crystalline mass which is formed is graded by screening using screens of mesh sizes of 35-325.  In this way isophthalic acid crystals of 98-94% purity are separated from the smaller crystals in which terephthalic acid predominates.  Instead of screening, other methods of grading the crystals may be used e.g. settling, elutriation, and centrifuging.  The fractions obtained may be further purified by re-crystallisation, or re-running. Specification 807,091 is referred to.
