Title: Member for providing the dispensing opening for an easy-opening container
IPC: B65D51/00
Filed: 1971-07-30
Abstract: 1350674 Easy-opening containers CONTINENTAL CAN CO Inc 30 July 1971 [31 July 1970] 35948/71 Heading B8D A metal container end comprises a removable score line-defined panel portion 12, and a band 14 of adhesive compound, which is formed on the inner container end surface to bridge the score line and which is adapted to separate without rupture from the panel portion on removal of the latter to mask the resultant raw edge of the remaining portion of the container end. The container end may be formed with a shock-absorbing bead 7, the side wall 15 of which provides a boundary for the band. The band is extruded on to the container end whilst the latter is rotated. Alternatively, the container end may be seamed to the container body 17 prior to application of the band, and, in the absence of the bead 7, the band may extend into the corner of the container. A pull tab (not shown) is riveted to the movable panel portion.

Abstract: 321,088. Brown, W. Dec. 7, 1928. Cable sleeves and like end constructions. - In fluid filled paper insulated cables, the lead cover 1 is extended beyond the core 2 at each end of a manufactured cable length to form a reservoir 3 for filling fluid so that when the seal is broken by puncturing the end wall of the reservoir 3, the filling liquid will enter the cable to destroy the vacuum therein.

Patent GB-1009545-A (GB)
Title: A circuit arrangement for testing lines in telecommunications and more especially telephone installations
IPC: H04Q3/00
Filed: 1962-09-21
Abstract: 1,009,545. Automatic exchange systems. SIEMENS & HALSKE A.G. Sept. 21, 1962 [Sept. 22, 1961], No. 36101/62. Heading H4K. In a circuit arrangement for testing the free or busy state of a line containing a complex impedance (e.g. a busying relay), the circuit includes an impedance which is placed in series with the line whereby the potential at the junction of the circuit and line immediately attains its steady state value (whereas the current flowing through the line rises relatively closely to its steady state value) and consequently the state of the line is immediately ascertainable from a measurement of the magnitude of this potential. The arrangement is applicable to a system using relay selectors in which step-by-step testing of the outlets or inlets is made. In a large system more than one testing circuit may be provided and these are so interconnected that simultaneous seizure of a single selector by more than one tester is prevented. As shown, a line includes windings IC and IIC of a busying relay, but in the free state the second winding IIC is short circuited. When a test is to be made, relay PH comes-up and connects the input J of the tester and an impedance chain DR which simulates the line impedance to the line. The potential at J then either renders T1 conducting or not in dependence upon whether the line is free or not. Consequently, T2 either cuts-off or stays-on and thereby switches-on (break-down of Zener diode D) or cuts-off T3 and T4. If the line is free, P pulls-up to apply a busy marking over leads S2 to S4 connected to other testers (cf. lead S1 of the tester shown) and thereby prevents simultaneous seizure of the selector associated with this line. In addition, PH falls-back and busy-potential is applied via R2 to the line, whereupon relay C is energized. A line which has just been released but which still has both of its C windings in circuit cannot be seized. If two testers simultaneously test the same line, then because two simulating impedances DR are connected in parallel with each other the potential at J is insufficient to trigger-off T1.

Title: Clay grease manufacturing process
IPC: G21C3/30
Filed: 1959-10-26
Abstract: Clay-gelled lubricating greases, which have been treated with a cationic surface active agent, are protected from undesirable hardening on storage by adding to the grease in the presence of not more than 5% by weight water, 0.25-1% by weight (based on the grease) of oil soluble amino-amides formed by reacting fatty acids having 14-22 carbon atoms, preferably 17-19 carbon atoms, with a mixture of polyethylene polyamines, 20-80% by weight of such polyamine mixture comprising polyamines having 2-3 nitrogen atoms, and the remaining fraction being polyethylene polyamines having an average molecular weight of 200-500, preferably 250-400, the ratio of fatty acids to polyamine being 0.3-0.6 eq./eq. and preferably 0.4-0.5 eq./eq.  It is preferred that not more than 0.5% by weight of water be present and that the amount of amino-amides added be 0.5-0.8% by weight.  The amino-amides are made by reacting the fatty acids, of which preferably at least 50% by weight consist of acids containing at least one double bond, such as oleic, linoleic, linolenic and tall oil acids, with the polyethylene polyamine, for example ethylene diamine, diethylene triamine, or the bottoms product obtained in the manufacture of ethylene diamine by reacting ethylene dichloride with ammonia, in the appropriate proportions at 125-250 DEG C., preferably 190-225 DEG C., for 0.5-16 hours, usually 1-4 hours.  The process comprises dispersing the clay, generally a bentonitic clay such as Wyoming bentonite or hectorite, in water in a concentration of 1-4% by weight adding to this dispersion lubricating oil and 40-100%, preferably 60-80%, by weight (based on the clay), of a cationic surface active agent which may be the same amino-amides described above, or the condensate of the reaction product of epichlorhydrin and ammonia with the fatty acids described above, and mixing at 50-85 DEG C. for example by agitation in a turbulent pipeline flow; 1-10% phosphoric acid (based by weight on the clay) may suitably be added to the dispersion of clay in water before addition of cationic surface active agent and oil.  The clay is present in an amount of 2-20% by weight of the final grease.  The water which separates is removed and the curd which remains subjected to high speed shearing in the form of a thin film, the temperature being so controlled that residual water is flashed out in 1-30 seconds; if required, a further amount of lubricating oil may be added prior to or during dehydration.  The amino-amides are then added to the grease, and the mixture heated to 125-210 DEG F., preferably 150-200 DEG F., for 0.5-8 hours, generally 1-4 hours.  To this product is then added 0.05-0.25% by weight of water.  If required 0.25-1% each of a corrosion inhibitor, such as sodium nitrite, and an oxidation inhibitor, such as phenyl-a -naphthylamine may be incorporated. Specification 703,169 is referred to.

Liquid reactants are contacted with gaseous reactants by passing the gas in the form of a sheet-like gas stream of substantially rectangular section at least three times as wide as thick, together with the liquid reactant in the form of an annular stream not more than 0À1 inch thick, into an elongated reaction zone of cross-section substantially the same as the gas stream, so that a film of liquid flows down the periphery of the reaction zone, surrounding the gas stream, the liquid compound being cooled prior to, and during, the reaction, and the product being finally separated from the gas mixture. A suitable form of apparatus is illustrated in Figs. 1, 5, 6 and 8, which are respectively a general front elevation, a plan section through the nozzle and annulus, a section in side elevation through the feed and reactor unit, and a section in front elevation through the separator unit. In this apparatus the gas mixture is introduced into the flared conduit 30 which ends in the nozzle 19. Liquid from the supply chamber 24, which is kept flooded, and from which air is previously removed via the air bleed 26, flows through the annular opening 21 between the nozzle 19 and the casing 15 into contact with the gas stream. Cooling is provided by the jacket 27, which is provided with inlet 28 and outlet 29, surrounding the casing 15. The reaction zone may be extended using further independently cooled units 12. In the separator 13, the liquid flows down the walls of the housing 34 and 35 and is removed via the discharge port 36, while the gas exhausts via the escape tube 31 and the outlet conduit 37, any entrapped liquid being withdrawn via the conduit 38 and the valve 39. The use of the apparatus is exemplified by a sulphonation process as described in Specification 1,007,995.

[Also in Group XXXIII] Direct lift for an aircraft is provided by means of two or more fans mounted for rotation about a common axis parallel to the axis of yaw and adapted to be driven in opposite or alternate directions. As shown in Fig. 1, part or the whole of the exhaust gases of the gas turbine engines 2, 3 may be diverted by means of valves 21-24 into volutes 12 and 15 and used to drive the fans.
