IPC: B65B/
Filed: 1967-05-27
Abstract: A pull tab 17 for opening a can is attached to a removable panel 15 by a rivet 18 which secures a flat portion 30 of the tab in which lies a C-shaped out 32, so that when a ring 20 of the tab is raised the tab pivots along a line joining the ends 33 of the cut 32 and thereby causes a nose 35 of the tab to break a weakening line 16 defining the panel 15. The tab is formed of sheet metal and the ring 20 which has curled under edges (23), Fig. 2 (not shown), is upwardly offset at 38. An upstanding rib 25 on the tab has a dependent flange (28), Fig. 3 (not shown), on either side and an upstanding flange (26) surrounding the flat portion 30, thereby making the tab more rigid. The rivet 18 is integral with the panel 15 and extends through an aperture in the tab. In a modification, Figs. 5-6 (not shown), the dependent flange (47) extends round the nose of the tab.

Title: Fuel injection nozzle and adjustable biasing means therefor
IPC: F02M61/10
Filed: 1968-01-12
Abstract: In a fuel injector, the spring-biased needle valve 16 has an adjustable valve lift stop 40 and an independently adjustable spring-loading stop 32. The spring 22 acts on the valve 16 through a spring seat 28, co-operating hemispherical surfaces on the valve and seat providing for an axially acting spring force on the valve. There is an interference fit between the stop threads and the threads 36 in the nozzle body 10 to maintain the stops in their adjusted positions. The stops 32 and 40 have threaded sections 64 and 66 and 72 and 74, respectively separated by struts 68 and 76. The helix of one of the threaded sections of each stop lags or leads that of the other section so that the struts 68 or 76 are under compression or tension to thereby hold the stop against movement and eliminate backlash in the adjustment.

Title: Process and apparatus for the enrichment of isotopic mixtures
IPC: B01D59/26
Filed: 1968-01-17
Abstract: Gaseous mixtures of isotopic constituents are separated into enriched fractions by differential sorption, e.g. on molecular sieves or on metal halides, by passing the mixture into a bed of the sorbent which has previously been saturated with a different inert 'buffer gas until the mixture has displaced the buffer gas and one enriched fraction has traversed the bed, discontinuing injection of the isotopic mixture and once more passing buffer gas through the bed to displace and separately collect at the outlet of the bed the various enriched isotopic fractions. In a preferred embodiment, a plurality of sorption units are used in cascade, the mixture to be separated being passed to the middle unit, the enriched head fraction therefrom being passed for further enrichment to the unit next downstream, the other enriched tail fraction being passed for further enrichment to the unit next upstream, and the intermediate fraction of similar composition to the original feed being recycled, with further similar enrichment being carried out in each unit. Particular separations described are 12C from 13Cby enrichment of carbon monoxide fractions using a 5A molecular sieve and helium as buffer gas 20Ne from 23Ne at the temperature of liquid nitrogen using a molecular sieve and helium as buffer gas 10B from 11B at 10 C. by enrichment of boron trifluoride fractions using "Chromosorb WAW" impregnated with dioctyl sulphide and nitrogen as buffer gas and 235U from 238U at 400 C. by enrichment of uranium hexafluoride using sodium fluoride and a mixture of nitrogen and fluorine as buffer gas.

Title: Cooling of rotary furnace shell burner pipes and method
IPC: F27B7/34
Filed: 1973-07-31
Abstract: Overheating of rotary kiln shell burner pipes has resulted in serious deterioration and severely limited service life in a number of operating furnace installations. Various measures have been applied in attempts to solve this problem, but with only limited success. This invention provides a positive solution by use of forced cooling employing an array of high-velocity air jets directed to impinge directly on the inner burner pipe walls. The apparatus includes an assembly of internal cooling header ducting within the burner pipe in an annular configuration, supplied with air under pressure, and equipped with an array of spaced jet nozzle openings through which cooling air jets are directed to impinge on the inner pipe surface, thereby effecting accelerated and continuous cooling of the burner pipe as it operates in the hot furnace atmosphere.

Patent ES-459127-A1 (ES)
Title: Boiler with horizontal boiler sections
IPC: F24H1/38
Filed: 1977-05-25
Abstract: Boilers with horizontal boiler sections contain in each section several heat exchanger elements for transferring the heat from the heating medium to the heat carrier medium. They have the inherent advantage of needing a connection between sections only on one side so that the dimensional changes during operations are easily equalized and no thermal stresses occur. Heretofore, it has been assumed that the frame of such horizontal boiler sections in which the heat exchanger elements in the form of pipes are secured must be provided with a cooling channel for the liquid heat carrier medium, and consequently the specific heat output in relation to the amount of material used for the construction of the boiler section was considerably decreased.
