Abstract: 1,160,468. Morpholine derivative. MAY & BAKER Ltd. 6 May, 1968 [8 May, 1967: 7 Nov., 1967]. Nos. 21240/67 and 50681/67. Heading C2C. Novel 2,6-dimethoxyphenyl 2-morpholinopropionate in the form of the racemate or an optically active isomer, and non-toxic acid addition salts thereof is prepared by:- (a) reacting a compound of the Formula III: where X is the acid residue of a reactive ester with morpholine. or (b) reacting a compound of the Formula IV where Z is hydrogen or an alkali metal atom: with a compound of the Formula VII: where X 1  is a halogen atom; or (c) reacting 2,6-dimethoxyphenyl 2-aminopropionate with a compound of the formula X-(CH 2 ) 2 -O-(CH 2 ) 2 -X, where X is as defined above, in the presence of concentrated sulphuric acid. Enantiomorphic forms may be obtained by resolution of the racemate, or use of optically active starting materials. ( - )-α-Bromopropionyl chloride is obtained by treating the corresponding acid with thionyl chloride and phosphorus trichloride. () - 2,6 - Dimethoxyphenyl 2 - bromopropionate is obtained by adding ()-α-bromopropionyl bromide in anhydrous benzene to a solution of 2,6-dimethoxyphenol and anhydrous pyridine in anhydrous benzene and then refluxing. (-) - 2,6 - Dimethoxyphenyl 2 - bromcpropionate is prepared similarly, but using ( - )- α-bromopropionyl chloride. Pharmaceutical compositions having local anaesthetic activity and containing 2,6-dimethoxyphenyl 2-morpholinopropionate and non- toxic acid addition salts thereof are administered parenterally in association with a pharmaceutical carrier. These compositions may also contain adjuvants such as preserving, wetting, emulsifying, dispersing and solubilizing agents. They may be sterilized, e.g. by filtration through a bacteria-retaining filter, by incorporation of sterilizing agents in the composition or by irradiation.

Abstract: 1465861 Microprocessors BURROUGHS CORP 22 Nov 1974 [21 Dec 1973] 50699/74 Heading G4A A microprogrammable computer system includes a central processor 11 associated with a plurality of peripheral devices, 15, 17, 19, 21, and a shared memory 25 which stores macroinstructions and microinstructions; the shared memory 25 has stored therein, in response to a user program, only those microinstructions which are needed for operating the peripheral devices required by the program and for carrying out the computations required by the program. The remainder of shared memory 25 is then available for storing macroinstructions. The storing of the required microinstructions may be controlled by a loader implemented as hardware or as microinstructions stored in a, read-only portion of memory 25. The storing of the required microinstructions in the memory 25 is controlled by header information loaded at the beginning of the user program; this header information includes a program name which identifies a parameter block specifying the firmware modules required by the program (binding information) and stored on discs, a code flag which is checked for validity, the disc address, where program loader binding information is stored and the length of the user program. Nano-instructions are stored in a further memory 23, which may be a read-only memory or of a non-destructive read-out type. The area of shared memory 25 containing microinstructions is "user-undumpable" whereas the rest of the shared memory 25 is "user-dumpable". The memory 25 may additionally have stored therein, in either the "user-undumpable" or the "user-dumpable" areas, buffer requirements, scratch pad memory, and user object codes.

Abstract: 1374114 Removal of volatile material from fluid mixtures which contain solid polymers FIRESTONE TIRE & RUBBER CO 2 Nov 1971 [27 Nov 1970] 50965/71 Heading B1B Crumbs of an elastomer, such as a high molecular-weight polymer of butadiene, isoprene and/or styrene, are obtained from a fluid mixture of the elastomer and volatile material by releasing the mixture from line 10, wherein the mixture is maintained above the boiling point of the volatile material but at a pressure sufficient to keep it in the liquid state, through an orifice into one end of an elongated conduit 13 at lower pressure whereby a portion of the volatile material is flashed into vapour and the remaining mixture forms discrete crumbs, the vapour velocity in the conduit being a magnitude from 3 to 70 metres per second. There may be more than one orifice. The conduit has a miniumum cross-section of about 250 times the total orifice cross-section area, and a maximum cross-section of about 10,000 times the total orifice cross-section area. The crumbs fall onto two oounter-roating rolls 15, are carried between the rolls and fall into a screw conveyor 16, then to hopper 17 and extruder 18 which removes the crumbs from enclosure 12. The rolls can be heated to a temperature of from 35 to 200C to assist in removing further volatile material. Nitrogen at a temperature of 90 to 200C. may be blown against the rolls. Hot nitrogen may be added to the fluid mixture before it is relased through the orifice. Vapours flow from enclosure 12 through line 19 to compressor 21 and condenser 23. The flash-conduit may contain baffles, an offset as shown in Fig. 6, or a constriction (Fig. 7, not shown). The conduit may swing (Fig. 9, not shown) so as to distribute the crumbs across the rolls;

Abstract: 1479578 Rotary valves for I C engines EXXON RESEARCH & ENG CO 21 May 1974 [24 May 1973] 51226/76 Divided out of 1471533 Heading F1B A rotary valve 36 is sealed relative to and rotatably mounted within a housing 33, 35 which is adapted for attachment to a cylinder 31 of an I.C. engine; the valve has a chamber 50 therein and an aperture 51 providing communication with a first port 55 in the housing, for passing an oxygencontaining gas into the chamber, and with a second port 52 which is adapted to communicate with the interior of the cylinder to allow the oxygen containing gas in chamber 50 to be discharged to the cylinder. The valve also includes an air/fuel inlet duct 46 which opens into one end-face of the valve and an exhaust duct 48 which opens into the other end-face of the valve. The valve rotates in a clockwise direction, as seen in Fig. 1, and while aperture 51 is passing port 55, air supplied by an engine-driven pump, passes into chamber 50 at a pressure of about 10 atmospheres. At the moment when ignition occurs, valve 36 has turned to a position where passage 51 communicates with port 52 so that the burning air/fuel mixture compresses the air in chamber 50 to cylinder pressure. As the pressure falls during the expansion stroke, the burning mixture is diluted with air which ensures complete combustion. Exhaust port 49 and passage 51 communicate simultaneously with port 52 so that chamber 50 is vented.
