Title: Process for the conversion of hydrocarbon oils
Filed: 1932-08-25
Abstract: <PICT:0405721/III/1> In cracking processes of the tube and pressure drum type in which the cracked products are passed wholly or in part to an evaporating zone, the residual materials remaining in the evaporator after evolution of vapours are reduced to coke by direct contact with a heat carrying medium selected from one of the further products of the reaction.  Crude oil is pumped through lines 3, 5 to a heating coil 6 and reaction chamber 8 maintained under pressure, and the liquid and vapours produced are removed together with reduction of pressure through a pipe 9 to one or more coking chambers 11 or alternatively the vapours are passed direct to a fractionating tower 14 and the liquid products only to the chamber 11 where they are coked with the aid of products of the reaction heated in a coil 33.  The vapours formed in the chamber 8 may be sent directly to the column 14 through pipes 12, 31 or may be passed through a line 51 to a column 53.  These columns are similarly constructed and comprise upper and lower compartments 14, 15 and 53, 54.  The reflux formed in the column 14 is returned by a pump 28 to the coil 6 for further conversion. Part of the crude oil and the reflux from the column 53 may be pumped through a pipe 29 to the column 14.  The vapours are further fractionated in the upper column 15 and the condensate formed may be withdrawn through a line 41 or returned to the system through lines 37, 43 or 40, while the vapours passing off at the top of the column are returned to the system through a line 45 or condensed in a cooler 18 and collected and separated from gases in a receiver 19. Part of this condensate or the gases formed in the reaction may be returned to the system through lines 96, 48, 50.  In a similar manner the products separated in the fractionating tower 53, 54 may be returned to the system through lines 63, 70, 76 or collected as a final product in a receiver 58, a part of the final product or the incondensable gases separated therefrom being recycled through lines 93, 74, 50.  One of the products returned to the system as set forth above is then selected and passed through a coil 33 from which it is led into the chamber 11 through a pipe 35.

Title: Improvements in the preparation of phosphates of bivalent metals
Inventor: RANBY PETER WHITTEN
IPC: C01B25/26
Filed: 1959-07-13
Abstract: Magnesium, calcium, strontium, barium, cadmium and manganese phosphates and zinc ammonium phosphate are prepared by preparing an aqueous solution containing the metal ions and phosphate ions, sufficient hydrogen ions to prevent the phosphate from precipitating, and also urea or a hydrolyzable urea derivative. The solution is then heated to hydrolyze the urea or hydrolyzable urea derivative, thereby reducing the hydrogen ion concentration, with the result that a homogeneous precipitate of the phosphate is obtained.  Impurities may be removed by first heating the solution so that a slight precipitate is obtained, filtering, and then heating the filtrate to effect complete precipitation.  A continuous preparation may be effected by passing the solution through a heated vessel or tube.  The product may be used in luminescent materials.  The phosphate ions may be added in the form of a soluble phosphate, for example ammonium phosphate, and the hydrogen ions may be provided by a mineral acid.

Title: Improvements in and relating to the control of pre-stressed rolling mills
Inventor: TRACY JOHN ANDRE
IPC: B21B37/64
Filed: 1963-06-20
Abstract: 1,100,581. Rolling. LOEWY ENGINEERING CO. Ltd. 2 Sept., 1964 [20 June, 1963], No. 24549/63. Addition to 955,164. Heading B3M. A method of controlling the operations of a prestressed rolling mill, in which screws 32 set the roll gap, includes the steps of measuring the rolling load in the screws and the prestressing load at 48 or 50, transmitting these measurements into electric signals, multiplying the signals by coefficients and using their compared values to produce a signal to control the prostressing force so that the influence of roll spring and chock spring on the roll gap is eliminated. The prestressing load is measured by a load cell 48 above the backing roll chock 14, or in the hydraulic prestressing circuit either at 50 or at the cylinder 36. Load cells 34 in the backing roll chock 16 measure the force in the screws 32 which extend between the chocks 14 and 16. The load signals, after multiplication by variable resistors R1 and R2 whose multiplication factors are K2 and (K1 + K2), where K1 and K2 are respectively the chock spring and roll spring, are subtracted to produce an intermediate signal. This signal is compared in the second stage of a comparator 52 with a reference signal indicating a desired roll gap from a potentiometer 54 to produce an error signal which is shown on an indicator 70. The error signal passes an amplifier 56 and causes an electro-hydraulic servo control valve 46 to vary the prestressing force applied to the mill.
