Title: Improvements in or relating to the synthesis of urea
IPC: C10K1/12
Filed: 1963-02-25
Abstract: Urea is synthesized by reacting ammonia with the carbon dioxide contained in a raw material gas containing nitrogen, hydrogen and carbon dioxide obtained by rendering suitable for use in the synthesis of ammonia the starting material gas conventionally used in said synthesis. The ammonia reactant may be that obtained in the subsequent ammonia synthesis. The raw material gas is preferably compressed to a urea synthesizing pressure and is brought into contact with an absorbent containing said ammonia in the liquid state and a medium capable of dissolving ammonium carbamate (e.g. water, aqueous ammonia, aqueous urea or a mixture thereof) to absorb in said absorbent substantially all the carbon dioxide contained in said raw material gas, the temperature of the resulting absorbate being kept at a value suitable for bringing about the synthesis of urea at the pressure employed.  The nitrogen and hydrogen is preferably fed from the urea synthesis reactor under ammonia synthesis pressure conditions to an ammonia synthesis reactor, the ammonia synthesized being fed back to the urea synthesis.  Where the original raw material gas contains carbon monoxide, this is removed prior to ammonia synthesis.
Patent GB-745426-A (GB)
Title: A method of solid-phase bonding metals
Inventor: BOESSENKOOL HELMICH WOLTER
IPC: B23K20/04
Filed: 1952-03-24
Abstract: 745,426. Jointing; working at specified temperatures. METALS & CONTROLS CORPORATION. March 24, 1952, No. 7589/52. Classes 83 (2) and 83 (4). [Also in Group XXIII] A method of solid-phase bonding metals comprises preparing the surfaces of the metals by eliminating any film which would act as a barrier to bonding, squeezing the prepared surfaces together and concomitantly effecting an increase in area thereof to form nucleal bonds 43, Fig. 2, the squeezing being carried out at a temperature below the minimum recrystallization temperature of the metal having the lowest recrystallization temperature, and thereafter subjecting the composite material to heat treatment to cause the nucleal bonds to enlarge. The squeezing may be accomplished by rolling mills in which strips or sheets are bonded, drawing dies in which a tube is bonded to a rod or another tube; strand or impact extrusion presses; and upsetting where two rods of metal are forced together endwise. Fig. 1 illustrates the squeezing step performed by rolling. Metal strips 1 and 3 pass through a surface preparation apparatus 11 and then through a sweep chamber 13 where loose dust is removed. Redeposition of dust is prevented by keeping the prepared surfaces in contact until the strips reach the rolling mill which effects a reduction in the total thickness of the strips of more than 30 per cent. The surface preparation comprises two steps: removal of gross contaminants and removal of films, e.g. of natural oxide which approach molecular dimensions in thickness and which either resist ordinary cleaning methods or reform after such cleaning. This second step may be effected by abrasion, bright annealing or pickling followed by heating to a temperature high enough to decompose the film or transform it into one which will not resist the bonding process. Such heating may take place in a furnace with a protective atmosphere or, alternatively, a blast of heated air, infra-red heat, or high frequency induction heating may be used. Abrasion is preferably effected by wire brushing (see Group XXIII) for a period which is adjusted to generate sufficient surface heat to decompose the film without creating a fresh detrimental oxide film. A neutral or protective atmosphere may be used. The wire brushes are degreased and then heated to destroy residual contaminants while the contacting parts, such as guides, are cleaned by sanding. The final heat treatment, which transforms the nucleal bond into a substantially continuous one and brings the metals to a softer condition, may be carried out at temperatures above or below the recrystallization temperature of either or both metals, but it is preferred to use a temperature between the lowest recrystallization temperature and that at which brittle compounds or liquid-phase material would form in appreciable amount. The Specification includes a tabular statement of the preferred method of heat treatment, mill operation and surface preparation for different combinations of metals.

Title: Improvements in the manufacture of glass hollow ware
IPC: C03B9/16
Filed: 1941-06-20
Abstract: 547,474. Glass manufacture. AUSTRALIAN GLASS MANUFACTURERS CO. PROPRIETARY, Ltd. June 20, 1941, No. 7775. Convention date, June 24, 1940. [Class 56] Relates to a method of preventing the appearance of "counterblow wave" in bottles or other hollow glass articles produced by forming-machines of the non-suction type, such as those described in Specifications 160,366, [Class 56], and 386,012. According to the invention, a number of separate charges of molten glass, instead of a single charge is delivered into a parison mould at different stages of the operation of forming a parison therein. The first charge 13, Fig. 1, delivered into an assembled parison mould 10 and ring mould 11 is preferably a. small quantity about equal in volume to the volume of the cavity in the ring mould. This charge is settled about the plunger 12 by pressure applied through a blowhead 14 applied to the open end of the mould 10. After the charge has been compacted, the plunger is replaced by another, 15, Fig. 3, with a central passage 16, and a second and final charge 17 of glass is fed into the mould 10. Immediately, a baffle plate is applied to the open end of the mould and the combined charge is counterblown with air supplied through the passage 16 in the plunger 15. A single plunger, formed in the known manner with small air-admission passages, may be used instead of the plungers 12 and 15. The charges are delivered by separate feeders, and if desired, the initial charge 13 may be formed of glass which is of different colour or composition from the final charge 17. In order to facilitate the settling. of the charge 13 and to allow air to escape from between the two charges, shallow grooves may be formed in the meeting faces of the halves of the ring mould and between these grooves and the mould cavity. These grooves may be connected with a port to which a suction pipe is connected to ensure the withdrawal of the air and to enable the charge 13 to be compacted by suction alone without the use of the blowhead 14.
