Title: Expendable immersion plug-in temperature responsive unit
IPC: H01R13/533
Filed: 1967-02-24
Abstract: 1,128,886. Thermocouples. LEEDS & NORTHRUP CO. 24 Feb., 1967 [28 Feb., 1966], No. 9021/67. Heading H1K. [Also in Division H2] In expendable immersion pyrometers for use in molten metal, it is customary for the temperature sensitive element to be a fine-wire thermocouple connected to short lengths of stouter wire of compensatory material, such material forming the contacts of one member of a plug-and-socket connection with the output leads of the complete pyrometer, which are usually contained in a manipulator into which the thermocouple unit is plugged. The invention proposes dispensing with these short stout leads and to make the wires of the active thermo-sensitive device itself from the actual contacts of the associated plug or socket member. Such wires have a diameter of less than 8 mils. Fig. 1 shows a thermocouple 13 consisting of Pt and Pt-Rh wires 14, 15. These wires pass into a tubular plastics member 10 and are folded over the bases of slots 11q and 11s in its walls and thence back along its outer wall. Fig. 2 (not shown) depicts an alternative form of the member 10 in which the slots are L- shaped and the wires pass through the horizontal limb of the L and are then folded not back as in Fig. 1 but forward (i.e. away from the junction end 16 of the couple). In either case the wires are sealed to the member, e.g. by local heating. The thus formed plug, of which the portions 14a and 15a of the wires 14 and 15 form the contacts, mates with a socket member 27 forming part of a manipulator for the unit. The contacts 22, 23 of this socket are of appropriate compensatory material and are attached to like compensating leads 30, 31. The bodies of the plug and socket are a snap-fit; both are of resilient material, and one has a bead 26a and the other a co-operating groove 11u (see Division H2).

Abstract: 981,587. Feeding webs. J. GAGG, H. A. STONE, R. E. M. GEMMELL, and MOLINS ORGANISATION Ltd. March 16, 1961 [March 16, 1960; Dec. 23, 1960 (2)], Nos. 9290/60, 4421/60 and 44211/60. Heading B6B. In a machine in which a paper web is fed continuously from a roll, e.g. in a continuous rod cigarette-making machine, a web splicing device is provided, the device comprising means to feed a replacement web 7 from a replacement web roll forwardly in lapped relationship with a moving expiring web 4, presser means including a roughened surface, arranged to press the webs into sufficiently intimate contact to create a join, detector means operative on the expiring web, means responsive to the detector means, when only a predetermined quantity of expiring web remains to actuate a friction pad arranged to engage the periphery of the replacement web roll to urge this roll to rotate, and means to operate the presser means. As shown, an arm 65 actuates a switch 64 when the expiring roll 1 reaches a predetermined diameter. The switch energizes a solenoid 63 which actuates an hydraulic valve 59 to cause a piston 56 to swing a lever 25 downwardly. A roller 14 presses the replacement web 7 against the moving web 4, such that the two webs are fed forwards. A catch 47 releases an arm 49 carrying a pad 52 which is swung forwards by a spring 50 to accelerate the replacement roll 5. A knurled roller 28 is swung down to press the two webs against a yielding plastic roller 12, thereby splicing the webs together. A knife 41 on a disc 39 cuts the expiring web. Upon de-energization of the solenoid 63, the valve 59 is returned to the position shown in Fig. 1, whereupon the lever 25 is raised to release the web from the nip of rollers 10, 14 and 12, 28. A slide 2 carrying the expiring roll 1 is removed manually from guides 3. When the roll 5 is sufficiently depleted an arm 75 actuates a switch 74 which engages a clutch 73 in the drive to a conveyer 70. The roll 5 is then moved to the right by a lug 69 carried by the conveyer until a switch 77 is actuated to disengage the clutch 73. In a modification, Fig. 3 (not shown) the leading end of the replacement web 7 is wound on a roll 102 to accelerate the supply roll and is subsequently cut by a knife 106. In another embodiment, Figs. 4 and 5 (not shown) the lever 25, Fig. 1, is actuated by the cam and lever mechanism, Figs. 4 and 5 (not shown). A web guide 201, Fig. 6 (not shown) forms the web 203 into U formation, the guide being adjustable by a screw 202. Rollers 204 mounted on ball bearings, not shown, engage the edges of the web.

Title: Manufacture of 4-dialkylaminophthalic anhydride compounds
IPC: C07D307/89
Filed: 1951-04-23
Abstract: The invention comprises 4-dimethylamino-, 4-diethylamino-, 4-dipropylamino- and 4-di-n-butylamino - phthalic anhydrides, and the preparation thereof by alkylating dimethyl 4-aminophthalate, saponifying the product to a disodium 4-dialkylaminophthalate, and finally removing the sodium and dehydrating to form the desired anhydride.  The alkylation is preferably effected by heating and agitating with the appropriate dialkyl sulphate in the presence of calcium hydroxide, the dimethyl 4-aminophthalate being extracted from the resulting pasty mass, e.g. with boiling benzene.  The saponification of the ester is preferably effected by heating with sodium ethoxide in ethanol, the disodium 4-dialkylaminophthalate being filtered off, washed with ethanol and dried.  The final anhydridization of this product may be effected by heating with acetic anhydride, after which a solution of sodium carbonate is added, the aqueous solution decanted or filtered and the residue dried.  An example describes the preparation of 4-diethylaminophthalic anhydride by the preferred procedure. Dimethyl 4-aminophthalate is obtainable by nitrating phthalimide (in the 4-position), heating the product with caustic soda solution and then just acidifying with nitric acid, esterifying the resulting 4-nitrophthalic acid with methanol in the presence of concentrated sulphuric acid, and then reducing the nitro group by means of zinc and hydrochloric acid in ethanol.
