Title: Production of tertiary alkyl ethers
IPC: C07C67/00
Filed: 1975-05-13
Abstract: 1506312 Tertiary alkyl ethers SNAMPROGETTI SpA 13 May 1975 [21 May 1974] 20209/75 Heading C2C A tertiary alkyl ester is produced by reacting an alcohol with an olefin having a carboncarbon double bond on a tertiary carbon atom in the presence of an ion-exchange resin in atleast two stages, whereinin one stage the alcohol is present in excess and in another stage the olefin is in excess. The reaction may be carried out using two reactors; all of one reactant is fed to one reactor while all or part of the other reactant is fed to the other reactor, and reaction products are at least in part circulated from one reactor to the other. The invention is exemplified by the reaction of isobutene in a mixed olefin stream with methanol to form methyl tertiary butyl ether. A suitable apparatus is described. Reference has been directed by the Comptroller to Specification 1,176,620.

The preservatives used may be rubbed into the substance and include borax and boric acid, which may be employed in admixture, benzoic acid and sodium benzoate, and the solvents include water or a mixture of water and alcohol. Auxiliary substances such as common salt may be added to the preservative or the solvent, or both. Up to 1 per cent of glycerine may be added to the solvent to increase its penetrating power.  The solvent may also contain in solution some of the solid preservative used.  The treated substance may be washed before delivery to consumers.  Specification 166,698, [Class 49, Food &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also preserving the substances by treating with a solution of a preservative, the temperature of which differs, e.g. by at least 5 DEG  C., from that of the substance treated.  The substance may be dipped into different preservative solutions having the same or different temperatures.  The substance may be treated first with a preservative solution and then with water or other liquid at a temperature differing from that of the substance.  This subject-matter does not appear in the Specification as accepted.

Abstract: 480,510. Couplings; brazing. BRITISH THOMSON-HOUSTON GO., Ltd. July 29, 1937, No. 21042. Convention date, July 29, 1936. [Class 38 (i)] [Also in Group XXII] A fluid-tight seal for the electric connections to a tubular heater is made by bringing the terminal 18, Fig. 2, of the heater 13 out through glass seals 19 into a sleeve 21 brazed at 24 to the heater casing 13, the sleeve 21 having an insulating liner 35 that forms an abutment for a series of resilient rubber blocks 36 with intermediate rigid washers 37 that are compressed by a screw 38 so that the blocks 36 press against the sleeve 21 and compress the resilient insulation 29 of the supply cable 27. The action of the screw 38 also forces a split socket 31 attached to the cable into endwise engagement with a coned flange 34 that compresses the socket on to a plug 32 attached to the terminal 18 by swaging at 32a. Alternative constructions of the compressing screw 38 are (1) an elongated member surrounding a lead sheathed cable to which it is soldered after screwing up, a rubber tube being slipped over it and packed with tape round the cable to stiffen the cable end, the nut and tube end being then covered with tape, Fig. 4 (not shown) or surrounded by a pipe connection screwed to the sleeve 21, Fig. 6 (not shown), or (2) a cap 94, Fig. 10, screwing on to the sleeve 83 and acting through a metal washer 92 tapered at 93 so as to expand a resilient washer 91 in the sleeve 83. A rubber reinforcing sleeve 96 is secured by a wire 97. This modification is applicable to the use of a magnesium oxide powder filling for insulating the terminal in the sleeve 83 and forming a continuation of the insulation of the heater which is made as described in Specification 144,767, [Class 38 (i)]. In brazing the sleeve 21 to the heater casing 13 a vent 25, Fig. 2, is employed to allow the air to escape as the brazing metal 24 is run in. The vent is afterwards plugged. The terminal casing may be elongated and formed at intervals with annular channels 70, Fig. 7, to receive the brazing metal introduced through lateral openings 71, a vent 73 provided between them being afterwards plugged and brazed over. Where the heater is mounted obliquely in a container the heater terminals may emerge obliquely through plate secured to the container, and stuffing boxes may be provided to allow longitudinal adjustment of the heater. Alternatively the sleeve 21 may be made with a reduced extension surrounding the end of the heater casing and, after welding together, the extension and heater casing are bent to the desired angle.

Ancillary units, which may be a pressure gauge, blood pressure monitor, pulse monitor, reservoir bag, suction unit, emergency oxygen supply, oxygen lack warning device, oxygen concentration meter, anaesthetic concentration meter, pressure relief valve, a patient breathing and inflating valve, or an excess vapour extraction assembly, may also be plugged into the rack. The rack may be divided into bays having indexing means to prevent anaesthesia or ancillary units being plugged into the wrong layer. The bays and units may be constructed on the modular principle. One form, Figs. 1, 2 (not shown) and Fig. 3 has a U-section bar 1 forming a rack with a removable back panel (5) and carrying a gas mixer (19). The rack has fluid-connections to vapouriser 6, 7 provided by spigots 8 to 11 engaging in inlet and outlet sockets in the vapourisers. The outlet of the mixer 19 passes via conduit 22 either to vapouriser 6 or vapouriser 7 depending on the position of a selector valve 20, the gas/vapour mixture from the chosen vapouriser passing via the valve to a connector 28 for connection to the patient. Pure oxygen is available at an outlet 30 of the mixer and may pass via conduit 29 to connector 28 on opening a valve 31. The fluid flow connectors on the rack may be self sealing when the units are removed. In one arrangement, Fig. 7, spring biased pistons 77, 78 close off the outlets of sockets 70, 71 when the unit is removed and communication is established between conduits 74 and 75 via the sockets and a by-pass line 76.
