Abstract: Process for preparing urea in which,
 in a synthesis zone, at a pressure of 125-350 bar and at the temperature belonging thereto, a urea synthesis solution containing carbamate and free ammonia is formed from carbon dioxide and an excess of ammonia,
 in a first decomposition step, at synthesis pressure or lower, a part of the carbamate is decomposed by supply of heat and the gas phase obtained in this process is condensed in a first condensition zone,
 in a second decomposition step, at a pressure of 4-40 bar, a further part of the carbamate still present is decomposed by supply of heat and the gas phase formed is separated off,
 in a further step, the remaining carbamate is removed in the form of a gas mixture containing ammonia and carbon dioxide, and this gas mixture is processed to form a solution of ammonia and carbon dioxide in water,
 and the remaining urea-containing solution is processed to form a concentrated urea solution. 
<??>The urea solution to be concentrated is introduced into the tubes of a shell and tube heat exchanger, the gas mixture from the second decomposition step is led into the shell side of heat exchanger at the end opposite the place where the urea solution to be concentrated is fed, the solution of ammonia and carbon dioxide in water is fed to the said shell side at a place located between the inlet for the gas mixture and the inlet for the urea solution to be concentrated, and the condensate is discharged from the shell side at the end where the urea solution is led into the tubes.

Title: Improvements in or relating to spare wheel carriers
IPC: B62D43/04
Filed: 1962-06-22
Abstract: Means for securing a spare-wheel 1 consists of a frame A pivoted at B and C on a wall 2, so as to trap the wheel against the wall, and means D for locking the other end of the frame A to the wall by means of a hook member 33 which is pivotable about pins 38 on a fixed nut 37 from a locking position as in Fig. 4 to a release position (not shown). The nut 37 is mounted on a bolt whose bead is on the other side of the wall 2 and which in the locking position holds the base of the hook member 33 hard against a fixed cross member 32 so that pivoting is not possible. The hook member 33 is U-shaped and its opposing sides are guided between the opposing sides of a U-shaped member 30 fixed on the cross member 32. When the bolt head 36 is turned the nut moves out, releasing the hook member 33 from constraint from the cross-member 32 and allowing it to pivot about the pins 38 to release the end of the frame A.

Title: Insulated gate field-effect transistor comprising a mesa channel and a thicker surrounding oxide
IPC: H01L29/417
Filed: 1968-06-06
Abstract: In a silicon IGFET with source and drain regions formed as juxtaposed inclusions in the face of a body or zone of opposite conductivity type an insulating layer of varying thickness overlies that face. Where the layer overlies the source and drain regions it is thicker than it is under the gate and consists of silicon oxide inset in the surface of the silicon. Such a device can be made from a 200 Áthick 10 ohm. cm. P-type silicon wafer by depositing overall a À2 Á silicon nitride layer from silane and ammonia, removing it except from the gate area, oxidizing the exposed areas in steam, forming windows in the oxide and diffusing phosphorus derived from phosphorus-doped silicon powder through them to form the source and drain, and then reoxidizing the surface. The nitride can be used as gate insulation but is preferably removed in hot phosphoric acid and the underlying silicon heated in steam to form an oxide layer the thickness and electrical properties of which may be improved by successive heat treatments in oxygen, nitrogen and wet nitrogen. If the surface is oxidized before provision of the nitride masking the oxide is re-exposed at this stage by etching and improved as described above. Another possibility is to convert the nitride directly to oxide by anodic treatment. In alternative methods the nitride is first applied also to the source and drain areas or even over the entire water face and the diffusion holes etched in it. In both cases the source and drain areas are oxidized after diffusion as described above. Apertures are formed in the oxide overlying the source and drain regions and aluminium gate, source and drain electrodes applied in conventional manner. Etching of the oxide layers is effected with a saturated aqueous solution of ammonium fluoride to which hydrofluoric acid has been added as this etches the nitride only slowly. Use of a layer of nitride on oxide as gate insulation is mentioned.
Patent ES-358094-A1 (ES)
Title: Acid regeneration
IPC: C01F17/20
Filed: 1968-09-12
Abstract: Cations are removed from an acidic solution by contacting it with an ion exchange resin in the hydrogen form, the contacting taking place while substantially all those cations which have more than one oxidation state are maintained in an oxidation state lower than their highest, and under conditions where this lower state is maintained. The acidic solution may be treated with a reducing agent, e.g. metallic Fe, SO 2 , metallic Al, or H 2 S, before contact with the resin, and the solution maintained in a non-oxidizing medium prior to and during the resin contact step. The acidic solution may be contacted with dry resin, and the product contacted with more resin, the acid then being eluted out. The cations may comprise iron. The resin may be backwashed, and regenerated preferably with a regenerant solution comprising sulphurous acid and a carbonyl compound, e.g. acetone, acetaldehyde, crotonaldehyde, cyclohexone, furfuraldehyde, isobutyaldehyde, or methyl ethyl ketone. The regenerant may be treated to recover SO 2 and the carbonyl compound. The recovery of SO 2 may cause salts, e.g. sulphites and oxides to precipitate, and these may be recovered. The acidic solution, after contact with the resin, may be heated to recover rare earth compounds, normally as a gel, by heating to 88-95 C. The acidic solution may be neutralized, before contact with the resin, either with a basic material, or by contact with a resin in the sodium form. The solid material is filtered off, and the iron in the solution reduced, and the solution then contacted with the resin.

Patent ES-361231-A1 (ES)
Title: Brake actuators
IPC: F16D65/14
Filed: 1968-12-09
Abstract: An internal shoe drum brake actuator comprises a housing 10 having an internal chamber 16 from which two aligned bores 12, 14 extend outwardly containing plungers 18, 20 with slotted inner ends in which rollers 22 of greater diameter than the plungers are mounted and a displaceable wedge 26 between the inner ends of the plungers which in operation bears on the rollers. The plungers act on brake shoes having return springs and outward movement of the plungers applies the brakes. Movement of the plungers is limited by pins 32 or a part of the housing 10 slightly enlarged on the face abutting the rollers. The wedge is mounted on a push rod 28 or a pull rod actuated by an hydraulic piston, a cam or a lever system. To allow pins 24 to be inserted through the rollers and the ends of the plungers the top of the housing is open and the rollers and plungers are rotated through 90 degrees. The rollers and plungers are then rotated back, pushed outwards and secured by a circlip 21 and cap 19. To ensure that the rollers and wedge remain coplanar they are enclosed in a T-shaped cage 34 which is biased against them by a cover-plate 38 to prevent rattle. The side walls of the housing may contain holes to allow the pins to be inserted without rotation. A side wall may be outwardly inclined so that the pins can be inserted with only partial rotation of the rollers and plungers. A bearing may be located between each pin and its roller.
