Title: Economizer support
Inventor: CONNELL JOHN MARTIN
IPC: F22D1/10
Filed: 1966-06-06
Abstract: 1,117,803. Heat exchanger tube supports FOSTER WHEELER CORP. 6 June, 1966, No. 25167/66. Heading F4S. An economizer comprises a plurality of side by side vertically orientated tube banks 14 disposed within a hot gas passageway 16 defined by four heat insulated walls 22, 24 and 18, 20, each of the tube banks comprising a plurality of horizontal straight tubes 32 having fins 40 and being connected by U-tube bends 34 to define a sinuous fluid duct extending between upper and lower headers 36 and 38 respectively, the U-tube bends resting on a plurality of horizontal shelf members 50 which lie adjacent the end walls 22 and 24 and extending between opposed, vertically extending, channel members 42, 44 and 46, 48. Vertical spacer bars 52 pass through the shelf members thus defining a series of compartments [54] each of which accommodates one U-tube, this resting obliquely against opposite bars. Such a mode of support allows free expansion of the horizontal tubes 32 whilst at the same time ensures that hot gases are obstructed in their flow immediately adjacent the end walls 20 and 22.

Title: Instrument for measuring a neutron flux
IPC: G21C17/108
Filed: 1965-06-16
Abstract: 1,104,858. Detecting neutrons. LICENTIA PATENT-VERWALTUNGS G.m.b.H. and DEUTSCHE GOLD UND SILBER SCHEIDEANSTALT. 16 June, 1965 [16 June, 1964], No. 25460/65. Heading G6P. A neutron sensitive thermocouple device has the junctions surrounded by powdered neutron sensitive and insensitive materials respectively. Thermal neutrons of flux to be measured initiate nuclear or radiation reactions in the sensitive material which generate heat and promote a potential difference in the thermocouple. The materials are electrical insulators and enclose both the thermocouples and the leads completely. Each unit is surrounded by a heat conducting tube, the outer diameter of which is reduced by draining and which is sealed to prevent the escape of fusion products. Gamma ray compensation is effected when the neutron sensitive and insensitive materials have the same atomic number.

Title: Improvements in or relating to bituminous compositions
IPC: C08K5/09
Filed: 1950-10-19
Abstract: Aromatic substituted C12-C30 fatty acids are prepared by condensing an aromatic material with an unsaturated or halogen C12-C30 fatty acid; specified acids include oleic, palmitoleic, ricinoleic, erucic, petroselenic, linoleic, linolenic, eleostearic, gadoleic and cetoleic acids, and halogenated-particularly chlorinated-stearic, palmitic and lauric acids.  The aromatic material may be a petroleum oil or an alkylated benzene, toluene, xylene and/or naphthalene or one of their homologues, and they may be produced by condensing an aliphatic olefin or polymerized lower olefin or a halogenated paraffin with an aromatic compound.  The olefin or halogenated paraffin should preferably contain 6 to 30 C atoms to the molecule.  An unsaturated aliphatic alcohol-containing more than 6 C atoms-or a terpene alcohol may also be condensed with an aromatic hydrocarbon.  The condensation may be catalytic-a Friedel-Craft reaction.  In examples, oleic acid is condensed, in the presence of aluminium chloride with (1) phenol extract of a light oil; (2) benzol alkylated with chlorinated petroleum.  Both were heated at 105-110 DEG  C. for 4 hours whilst being agitated, and then treated with super-heated steam at 150 DEG C.  The products were distilled at 235 DEG  C. under pressure of 7 mms. mercury.  The residue is the acid, which is incorporated with bitumen.ALSO:A bituminous emulsion is prepared by disposing in aqueous alkali a bitumen of poor emulsibility and a minor amount of an aromatic substituted C12-C30 fatty acid or acids. These acids may be synthesized (see Group IV (b)) or derived from easily emulsified bitumens (see Group V).ALSO:A bituminous composition comprises a bitumen of poor emulsibility and a minor proportion of an aromatic substituted C12-C30 fatty acid or acids.  The amount of acid added is such as to raise the acid index of the bitumen to between 0.5 to 3. The acids may be prepared synthetically (see Group IV(b)) or obtained from an easily emulsified bitumen, e.g. by extracting an oily distillate with alcoholic alkali and regenerating the acid from the so formed soaps.

Title: Pneumatic Control Arrangement for a Counter-Stroke Hammer
Inventor: SZEDLACSEK JOZSEF
IPC: B21J7/46
Filed: 1967-06-07
Abstract: 1,181,856. Forging hammers. DIOSGYORI GEPGYAR. 7 June, 1967, No. 26394/67. Heading B3H. A pneumatic hammer of double-drive construction has separate control valves 9, 10 for the admission and exhaust of air from the cylinder 16, both valves being actuated by pneumatic pistons 20, 6 controlled by slide valves 4, 5 each connected to its respective piston space 27, 28 through two ducts 24, 13 and 26, 30 respectively, for admission and exhaust of air. The hammer tups 1, 2 are actuated by a piston in cylinder 44 whose lower annular space 39 is open continuously to pressure air through ducts 36, 38. Supply of air to upper space 16 is controlled by slide valve 9 biased to a closed position by spring 7 and actuated by piston 20. The space 7 in front of this piston is connected through admission duct 24 and exhaust duct 13 to the spring-biased slide valve 4 operated by remote control. For performing a working stroke the valve 4 is moved to the left, whereby air is admitted through ducts 18, 24 to space 7 thereby moving piston 20 and slide valve 9 to the right to admit air into cylinder space 16. During the working stroke, valve 9 closes, whereby the pressure air expands to complete the stroke; the cut-off position is variable. The exhaust valve 10 is closed during the working stroke by admission of air into piston space 28 under remote control by slide valve 5. At the end of this stroke, valve 5 is moved to the left whereby the space 28 is connected through duct 30 with exhaust 31. Exhaust valve 10 is thus opened by its spring 34 to connect cylinder space 16 with exhaust port 35. The tups are thus retracted by the air in lower cylinder space 39. During this retraction, a further control valve 17 is actuated to close the exhaust valve 10 and thus cushion this stroke. The movements of pistons 20, 6 are also cushioned by closing of ports 11, 12 and thus trapping air in the outer cylinder spaces 32, 33. Valves 14 prevent vacuum occurring in these spaces. The slide valves 4, 5, 17 are actuated by linkages or by an electric system.
