Abstract: The present invention provides a process for the preparation of compounds of the general formula 
<CHEM>
 wherein A represents the residue of an aromatic ring forming the whole or a part of a monocyclic or polycyclic, at least partially-aromatic, carbocyclic and/or heterocyclic ring system, optionally bearing one or more other substituents inert to the reactants here employed, and R represents an optionally-substituted alkyl, alkenyl, alkynyl or benzyl group having up to 12 carbon atoms. According to the process of the invention such compounds are prepared by causing an aromatic compound of the general formula: 
<CHEM>
 wherein A is as defined above and X represents a chlorine, bromine or iodine atom, to react with an alcoholate of the general formula: 
<CHEM>
 in which M represents an alkali metal or an alkaline earth metal atom; n is the valency of M; and R is as defined above, in the presence of a catalytically-effective amount of an active catalyst mixture comprising:
 (i) a formic acid ester of an aliphatic organic alcohol having the general formula:
 R<2>-O-CO-H (V)
 in which R<2> represents an optionally-substituted alkyl, alkenyl, alkynyl or benzyl group having up to 12 carbon atoms; and
 (ii) a cuprous salt;
 in a liquid medium which is a solvent for the catalyst mixture and in which the compound of formula II is at least partially soluble, under substantially anhydrous conditions and a nonoxidising atmosphere, to yield the desired corresponding compound of formula VI.

Abstract: A process for the preparation of urea at elevated temperatures and pressures in which ammonium carbamate is decomposed into ammonia and carbon dioxide and separated from the urea product stream in at least two pressure stages. The product urea stream having reduced ammonium carbamate content leaving the first high pressure stage is reduced in pressure to a level intermediate the pressure of the high pressure stage and the next pressure stage in a pressure reducing device in which the energy released by the pressure reduction is converted into kinetic energy by means of which a gaseous mixture of ammonia and carbon dioxide resulting from the carbamate decomposition in a further pressure stage or recovered the process condensate formed in a concentrating stage is compressed to the intermediate pressure. The resulting compressed mixture is thereafter condensed, and the condensate thus formed is pumped to the high pressure stage.

Abstract: A transfer apparatus wherein the conveyed loads, which need not absolutely possess a square or rectangular cross-sectional area or configuration, are received by or delivered from a transport vehicle, without the load itself having to experience a tilting movement, when it departs, for instance, from a stationary chain conveyor and is taken-over by the chain conveyor of a displacement carriage. The gap between the stationary chain conveyor and the chain conveyor mounted upon the transport vehicle is bridged by the laterally movable displacement carriage. The related chain drive serves for moving the conveyor chains of the chain conveyor and the displacement carriage. An alternately effective brake-locking device controls both movements. With blocked conveyor chains the displacement carriage, depending upon the direction of rotation of the drive motor of the chain drive, moves laterally in one or the other direction until reaching a related lateral stop or impact member. With released conveyor chains and blocked displacement carriage the conveyor chains of the chain conveyor are displaced until the conveyed load can be transferred or received, as the case may be.

Abstract: The invention relates to a method and an apparatus for the treatment of surfaces of a workpiece of carbon-containing cast iron, and in particular of blind holes in gray iron cast workpieces, by electrochemical stock removal and mechanical reaming-and-plating. Electrochemical stock removal and mechanical reaming and plating are carried out in separate steps whose operating parameters are independently adjustable, the mechanical stock removal being essentially confined to a reaming-and-plating of the surface which does not entail a closing of graphite flakes. A cylinder bore produced by the method of the invention with desired roughness will have a dark, lustrous surface.

Abstract: Disclosed is an apparatus useful in controlling the operation of ovens of the type typically associated with baking food products. Broadly, the apparatus permits the linear display of heat input to one or more zones of an oven responsive to gas flow. Heat input is indicated by fluid levels in manometers having their legs dimensioned to permit linear display of heat input despite the variance of gas flow with the square of the pressure. The manometers are positioned next to an adjustable scale which accommodates combustible gases of varying heat contents. The adjustable scale is preferably marked for the preferred heat input profile across the various zones of the oven to facilitate control of optimum heat input to the oven as a whole. Also disclosed are similar display devices for exhaust gases.

Abstract: A method of transmission or storage of a television picture involves dividing it into a plurality of blocks, subjecting them individually to a two-dimensional unitary transformation, transmitting or storing the transform coefficients and reconstructing the original blocks by the use of the inverse transformation. To reduce the data rate, the zero sequency coefficient is omitted for most or all the blocks, and the mean levels of the reconstructed blocks are adjusted to reduce visible brightness changes between them. The adjustment may be made to reduce the means square differences between the elements in two blocks along the common boundary. The division into blocks may give common elements in two blocks along each inter-block boundary. If a picture transition coincides with a block division an indication of this may be sent so that differences between elements along the division are ignored.

Abstract: A fluidized bed for treating of product at high temperatures (1100°C to 1300°C) is possible, while overcoming problems such as slow start up times and contamination due to combustion gas. The fluidized bed uses an inert gas introduced to the bed to cause fluidization of refractory particles. Exposed surfaces or boundary layer of the bed are heated by infrared radiation produced exterior to the bed and absorbed by exposed particles of the bed. The thermal characteristics of the bed insure rapid dissipation of the absorbed energy. Electrically powered lamps produce the radiation and preferrably are high intensity shortwave infrared radiation lamps. The lamps remain out of direct contact with the bed preferrably separated by a quartz wall or screen.

Abstract: The present invention relates to a method of excavating a storage complex in rock for storing radioactive material, or other harmful material. The complex to which the method relates comprises a-hollow body which is formed from a solid material and the interior of which constitutes a storage space for the radioactive material or other harmful material to be stored. The hollow body is located in an inner cavity (4) which is excavated from the rock and which has larger dimensions than the hollow body. The hollow body is spaced from the outer walls of the inner cavity (4) such as to leave a space which is filled with an elastoplastic, deformable material. At least one vertical shaft (2) is driven partially through the location of the space (4), and the space is excavated from the bottom of the shaft (2) and upwards, while filling the space or cavity (4) thus formed substantially at the same time as the cavity is formed.
