Abstract: 1536146 Water heating boilers; heatexchangers VALOR NEWHOME Ltd 25 June 1976 [28 June 1975] 27436/75 Heading F4A A gas-fired water-heating boiler is formed from a burner 10 and a heat exchanger 12 com-  prising an array of water tubes arranged about a burner space and end chambers 22, 36 diverting flow through the tubes so that the total cross-sectional water flow area decreases between an inlet 24 and an outlet 26. Water enters an annular chamber 22 from inlet 24 and is confined by partitions 28 to flow through the lower fire tubes 34 of the array to the chamber 36. As shown in Fig. 3 a partition 42 in chamber 36 allows return flow only through two tubes 44 back to the upper portion of chamber 32. Two tubes 46 then allow water to come back to the chamber 36 above the partition 32 and a final tube 48 carries the water to outlet 26. The water therefore passes through fewer tubes as it crosses between the end chambers and its velocity increases towards the outlet. The tubes have transverse fins 52 and can be axially ribbed on their interior if necessary.

Patent GB-835669-A (GB)
Title: Improvements in manufacture of para-amino diphenylamine
Filed: 1958-08-29
Abstract: A process of producing p-amino diphenylamine comprises reducing an alkali metal salt of p-nitroso diphenylamine with hydrogen while the metal salt is dissolved in water and while agitated with an hydrogenation catalyst.  The nitroso compound is said to exist in the tautomeric oxime form in the presence of alkali and to form a metal salt.  The reduction may take place in the presence of an inert water-insoluble organic solvent or at an elevated temperature, e.g. up to 100 DEG  C., to keep the amino diphenylamine in solution and prevent it coating the catalyst and reducing its efficiency.  When an organic solvent is used the base is recovered from it in the form of an hydrochloride.  In the examples the potassium or sodium salt of p-nitroso diphenylamine is reduced in the presence of platinum oxide or palladized charcoal in the presence or absence of benzene or xylene.

Abstract: 935,824. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. Sept. 24, 1959 [Sept. 1, 1958], No. 27977/58. Divided out of 935,823. Class 4. An air-cushion vehicle in which the cushion is contained at least in part by a curtain of moving fluid issuing from a position in the lower part of the vehicle, recovery means spaced outboard of and a short distance from the means supplying a primary curtain, and means spaced outboard of the recovery means for forming a region of pressurised gas outboard of the recovery means so that the fluid forming the primary curtain flows first downward towards the supporting surface, being deflected round and outwards by the pressure of the cushion when formed and is further deflected round and upwards by the pressure in said region of pressurized gas outboard of the recovery means so as to be at least partly recovered into the recovery means. The vehicle may be formed with the arrangement of duets and ports shown in Fig. 2 so that two peripheral concentric curtains 2 and 3 are formed. Air from a supply duct 6 is discharged from a supply port 7 and is caused by the pressure of the supporting cushion to flow into an inlet transfer port 9, through transfer duct 8 and out of outlet transfer port 10. Additionally, air is discharged from port 11 to form a further curtain which results in the formation of a region 13 of pressurised gas which causes the inner curtain to flow up into transfer port 9. In Fig. 7 an ejector nozzle 29 generates a vortex flow out of port 25, through transfer port 27 and duct 28. A separate curtain issues from nozzle 31 to contain pressurized gas in region 32.
