Title: Preparation of urea
IPC: C07C273/16
Filed: 1967-04-05
Abstract: Urea is extracted from the synthesis mixture obtained in the synthesis of urea from ammonia and carbon dioxide in a synthesis reaction vessel at elevated temperature and pressure by expelling the products contained therein which have not been converted into urea at a pressure of 100-300 atmospheres with a gas mixture which, before the expulsion commences, consists in larger part by volume of carrier gases which are inert as regards the urea synthesis and in smaller part by volume of ammonia or carbon dioxide.  The expulsion process may be carried out either in a separate apparatus to which the synthesis mixture is fed from the reaction vessel or in the reaction vessel itself, suitable inert gases being nitrogen, hydrogen and mixtures thereof.  The inert carrier gas may be circulated, in which case unconverted reaction constituents may be partially stripped off in an after-connected absorber condenser with approximately total absorption of one of the reaction constituents, while part of the other reaction constituent is recirculated again with the carrier gas to the expulsion apparatus.  The present process may be operated in conjunction with an ammonia synthesis process wherein, for example, the gas mixture obtained in the ammonia synthesis may be withdrawn before or after partial separation of the ammonia and may then be returned to the ammonia synthesis as a charging gas after passing through the expulsion and stripping apparatus of the present urea extraction. Suitable forms of apparatus are described for both batchwise and continuous operation of the process of the present invention.

In a colour television picture tube of the kind utilizing a metallic backed screen of colour phosphor dot or strip elements on to selected ones of which one or more electron beams are directed by means of a metallic grid or perforated mask maintained at a potential which is lower than that of the metallic screen, correct rendition, particularly at wide angles of scan, is ensured by varying the potential of the grid or mask as a particular function of the angle of scan. Figs. 1 and 2 show an example of a tube utilizing a grid electrode 1 which directs a single beam 6 on to selected colour phosphor strips forming the screen 2 which is backed by a metallic coating 3. The latter is maintained at a potential U 2  which is higher than the steady potential at which grid 1 is maintained (preferably by a factor of three to four) and in accordance with the invention a correction voltage U 1#  is superimposed on the steady potential of the grid 1 where K being the factor by which U 2  exceeds the steady potential of the grid 1 and α and # are the vertical and horizontal components respectively of the angle of incidence # of the electron beam on grid 1. If desired, the term involving α or the term involving # may be replaced by a suitable constant so that a correction voltage comprising an approximation which varies as a function of tan<SP>2</SP># or of tan<SP>2</SP>α, respectively, is produced.

Abstract: 560,014. Maximum demand meters ; self-supporting resistances. EVENDEN, E. F., and P. & B. ENGINEERING CO., Ltd. Nov. 18, 1942, No. 16313. [Class 37] A maximum demand indicator of the thermal type for polyphase circuits is provided with two or more heating elements connected to the load or supply circuit by current transformers having their secondary windings connected to the heating elements in such a manner that each element is heated by a current representing the resultant of currents in more than one phase. A pointer a, Fig. 1, is suspended by main and compensating coils b, b<1> consisting of bimetallic strip. The main coil b is heated by elements c clamped between the parts d, d<1> of a heat accumulator block which determines the time tag, the compensating coil b<1> being shielded by a screen. This block and the pointer suspension, as well as the maximum indicating pointer a<1>, are carried by two crossbars e, e<1> fixed to a pair of blocks f carrying the scale. f<1> and fixed by pillars f<2> to a triangular frame g, the three comers of which are mounted on springs g<1>. An insulating rail i carries three terminals j for the connections to the heating elements. Three separate transformers n are contained in a rear casing m and have their primaries connected by leads o to the phases of the external circuit. The three heating elements. c may be combined in a single metal stamping comprising three concentric arcuate portions with projecting horns c<1>, Fig. 3, for attachment to flexible leads k. The three heating elements are thus delta-connected and fed from the transformer secondaries, which are themselves connected in delta by leads l. Star, zig-zag, double delta, double star, or other connections may be employed instead of delta. For large currents the indicator may be provided with independently mounted transformers, for example of the split-core type fixed over the main conductors, which form the primaries.

Abstract: 775,726. Making bags. SCHWEIZERISCHE INDUSTRIE-GES. June 7, 1955 [June 8, 1954], No. 16327/55. Class 94(2). A device for opening up a flattened tube of material being fed, for example, to a bag making machine, comprises a slider floating freely within the tube but positioned during movement of the tube relative to it, by means surrounding the tube. In one embodiment, Fig 1, a tubular web 1 passes over a slider 2 held stationary by projections 17 on a fixed member 3. In other embodiments, not shown, the tube may move vertically and gravity locate the slider relative to the outer member, or magnetic means or a combination of methods may position the slider. To reduce risk of damage to the tube, one, or both parts, 10, 11, Fig. 6, of the device may carry rollers. A clamp 12 may be provided for temporarily securing the tube to the device. The device may co-operate with a rotating conveyer 26, Fig. 9, having a series of grippers 25 which grip the tube 24 as it is pulled upwards by vertical movement of the device 20, 27. During upward movement, the tube is immobilized against the slider 27 by a clamp 21, but after it is gripped by a clamp 25, the clamp 21 is raised and downward return movement of the device opens up a further length of tube. This length is severed by blades 28, and removed by a rotary step of the conveyer 26.

Abstract: 6 - Cycloalkylmethyl - 2 - thiouracils are prepared by reacting thiourea with a g -cycloalkyl-b -oxobutyric acid ester, wherein the cycloalkylmethyl radical has 4-7 carbon atoms, in the presence of a strong base, such as an alkali metal alkoxide, as a condensing agent. Suitable cycloalkymethyl radicals include cyclopropylmethyl, alkylcyclopropylmethyl, cyclobutylmethyl, alkylcyclobutylmethyl, cyclopentylmethyl, methylcyclopentylmethyl and cyclohexylmethyl.  In examples: (1) ethyl-g -cyclohexyl-b -oxobutyrate is reacted with thiourea in alcohol in the presence of sodium ethoxide to give 6-cyclohexylmethyl-2-thiouracil, and (2) ethyl - g  - cyclopentyl - b -oxobutyrate similarly gives 6 - cyclopentylmethyl-2-thiouracil. Cycloalkyloxobutyric acid esters are prepared by reacting a cycloalkylacetyl halide with ethyl acetoacetate followed by removal of the acetyl group from the resultant acylated oxoester, or by reacting a cycloalkylacetyl halide with malonic ester followed by the removal of a carbethoxy group, e.g. ethyl-g -cyclohexyl-b -oxobutyrate is prepared from cyclohexylacetyl chloride and ethyl acetoacetate, and ethyl g -cyclopentyl-b -oxobutyrate is similarly prepared from cyclopentylacetyl chloride.  Cyclohexyl- and cyclopentylacetyl chlorides are prepared by reacting cyclohexyl- and cyclopentylacetic acids with thionyl chloride.  Cyclopentylacetic acid is prepared by hydrolysing ethyl p  cyclopentylcyanoacetate with aqueous potassium hydroxide and distilling the product in vacuo. Ethyl cyclopentylcyanoacetate is prepared by the catalytic reduction of ethyl cyclopentilidenecyanoacetate.  Ethyl cyclopentylidenecyanoacetate is prepared by refluxing a benzene solution of ethyl cyanoacetate with cyclopentanone in the presence of acetic acid and ammonium acetate.
