IPC: H02P6/10
Filed: 1969-07-17
Abstract: 1,273,630. Electric motors. MATSUSHITA ELECTRIC INDUSTRIAL Co., Ltd. 17 July, 1969 [9 Oct., 1968], No. 36160/69. Heading H2A [Also in Division G3] The current supplied to the stator windings of an electric motor is controlled in dependence on both rotor position and rotor speed to maintain the speed at a desired value. The motor has an annular permanent magnet rotor 20 mounted radially externally of the stator and having alternate N and S poles around its inner periphery, the stator having three windings W1, W2 and W3, Fig. 3, controlled by transistors 50, 51 and 52 which are successively rendered conductive in dependence on rotor position. A toothed disc 25, Fig. 2, mounted on the rotor shaft radially within the stator, co-operates with respective pairs of primary and secondary windings mounted on poles 29, Fig. 1 (not shown), on the inner periphery of the stator so that the voltages induced in the secondary windings S1, S2, S3 depend on rotor position and are used to control transistors 44, 45 and 46 which in turn control transistors 50, 51 and 52. The rotor speed is maintained at a desired value by diodes 55, 56, and 57 producing at point 58 a rotor speed dependent voltage which is compared with the voltage across a zener diode 42 to control the base bias of a transistor 48 which controls the emitter currents of transistors 44, 45 and 46 and hence the current supplied to the windings. The speed may be adjusted by varying one of the resistors 59, 60. The rotor is mounted directly on a gramophone turn-table 10 supported on an anti-friction ball bearing 13, Fig. 2.

Title: Improvements in or relating to heterocyclic amides and carboxylic esters thereof
IPC: C09K23/00
Filed: 1953-12-30
Abstract: The invention comprises compounds of formula <FORM:0745036/IV(a)/1> wherein R is the residue of an anhydrized hexane pentol or a carboxylic acid ester of such residue, R1 is a monovalent hydrocarbon radical and -CO.R2 is the acyl radical of a carboxylic acid containing 2 to 25 carbon atoms.  The unesterified amides are prepared by stirring the appropriate carboxylic acid into a hexityl amine in equimolecular quantities at elevated temperatures followed by heating the resulting mixture at 175-220 DEG  C. until two or more mols. of water have been eliminated.  The esterified amides are prepared either by employing two or more equivalents of carboxylic acid in the above reaction or by subsequent esterification of the unesterified amides with a carboxylic acid (preferably containing 2-25 carbon atoms) or a halide, anhydride or ester thereof.  Hexityl amine starting materials include N-alkyl, N-alkenyl, N-cycloalkyl and N-aryl glucamines and fructamines.  Acylating acids include fatty and hydroxy fatty acids; aromatic carboxylic acids; phenoxy-, chlorophenoxy- and chloro-acetic acids.

Title: Improvements in and relating to the filling and closing of bottles and the like
IPC: B67C7/00
Filed: 1932-12-21
Abstract: 399,350. Bottle-cleaning machines. SEITZ-WERKE GES., Bad Kreuznach, Rhineland, Germany. Dec. 21, 1932, Nos. 36224, 36225, and 36226. Convention dates, Feb. 10, Feb. 11, and July 6. [Class 138 (i).] In a process for filling and closing bottles and similar vessels in a manner free from bacteria with the use of filling-machines and, if desired, closing-machines operating in a sterile manner, the bottles from a cleaning device are fed automatically or semi-automatically to the filling and closing stations and in their passage from the cleaning-machine to the filling station they traverse a sterilizing zone, which may be the final station of the cleaning-machine or the first in the filling-machine, in which they are rendered free from bacteria by means of a gaseous sterilizing medium, such as sulphur dioxide, ozone, or ozonized air. From the cleaning-machine 1 bottles are transferred automatically or semi-automatically to a conveyer 2 thence through a sterilizer 3, 6, a sterile filler 4 and a sterile closure applying machine 5. The conveyer 2 may be protected by a cover or current of sterile gas to prevent entry of bacteria. The sterilizer 3 may be formed as in Fig. 3, in which a table 8, pillar 12, and distributing sockets 14 are rotated, compressed air for lifting the bottle rests 11 being admitted through pipes 18, 17 to lifting cylinders 9. On being lifted, a blower pipe 21 depends into the bottle and a centring funnel 23 is pressed upwardly by the bottle top to seat against a sleeve 22 which in turn bears against a seat 29 to lift valve 19 against spring action 14. In the meantime, a tube 30 has arrived at a groove 38 in the cone 35 and sterilizing medium passes through tubes 36, 30 into the bottle. Escaping at 43, this medium passes a non- return valve 26, through pipes 27, 33 into the atmosphere, by way of a filter, if desired. In the meantime, due to the further motion of the table 8, the tube 30 has left the groove 38 and is closed until it registers with groove 39 which is connected through tube 37 whereby scavenging air, free from bacteria, is forced through driving out the sterilizing medium to the outer atmosphere. On the lowering of the bottle rest, the valve 19 closes. In a modified arrangement, the sterilizing gas from one bottle is passed into the following or preceding bottles in succession before going to the outer atmosphere, and in this event each sleeve 22 is connected with the inlet socket 14 for the next bottle above the valve 26 by means of a flexible pipe, a bridging pipe also being fitted to byepass the gas if no bottle is present; pipe 33 is then unnecessary and may be omitted. In this latter construction, extra grooves 46, 47 may be formed in the fixed cone 35 to connect to the outer atmosphere. The sterilizing medium is preferably moistened by being passed through a moistening chamber. Specification 345,001, [Group XVII], is referred to.

Title: Process for converting alcohols into ethers
Filed: 1934-12-19
Abstract: Alcohols are converted into the corresponding ethers by passing the vapour first over a metallic oxide catalyst and then over a catalyst consisting of one or more metallic sulphates or chlorides.  When ethyl alcohol is passed over the oxide catalyst at 300 DEG  C., ethylene is produced, and this on treatment with the second catalyst at 50--400 DEG  C. is converted into ether.  The second catalyst preferably contains a silver salt, and may contain a double salt of ammonium, or a cobalt amine.  The oxides for the first catalyst may be aluminium, ferric or chromium oxides, and the salts for the second catalyst may be potassium, sodium, ammonium, and lithium sulphates and bisulphates, magnesium, calcium, copper, manganese, nickel, zinc, and silver sulphates, magnesium, copper, nickel and stannous chlorides, magnesium-potassium chloride, and sodium, potassium, and ammonium alums or mixtures thereof.  In an example, 90 per cent ethyl alcohol vapour is passed successively over the two catalysts as above described and the reaction vapours are passed through a dephlegmator to a condenser.

Abstract: 1406791 Fibres TEIJIN Ltd 7 Aug 1972 [7 Aug 1971 20 Sept 1971 9 Nov 1971 28 Feb 1972] 36729/72 Heading C3R [Also in Division B5] Flame-resistant fibres are prepared by meltspinning a composition comprising 60 to 90% by weight of a fusible, curable novolac-type phenolic resin and 10 to 40% by weight of a fibre-forming polyamide. The melt-spun fibres are then cured with formaldehyde in the presence of an acid catalyst to give infusible fibres. The composition may comprise CuCl 2  or 2,6- t-butyl-p-cresol as stabilizer. The novolac resin may be modified to give a phosphorus content of 0À5% by weight, based on the total composition, by reaction with a phosphoric acid triester in the presence of the polyamide before spinning. The triester has the general formula where R 1 , R 2 , and R 3  may be the same or different and represent phenyl groups optionally substituted with halogen or alkyl groups. The reaction gives a product in which 0À8 to 1À5 equivalents of the ester groups of the phosphoric acid triester are ester interchanged. The cured fibres may be further fire-proofed by treatment with at least one polyhalogeno compound having at least two halogen atoms directly linked to an atom of P, S, Si, B, or Ti. The examples illustrate the use of nylon-6, nylon 6,6 and polymetaxylylene adipamide as polyamides and phenol-formaldehyde mixed cresol- and m-cresol-formaldehyde as novolac resins. In Example 5 the phenol-formaldehyde resin is treated with diphenyl phosphorochloridate before spinning and in Example 6 the novolac is ester-exchanged with triphenyl phosphate in the presence of the polyamide. In Example 7, the novolac is reacted, in the presence of the polyamide, with triphenyl phosphate, tricresyl phosphate, tri-p-chlorophenyl phosphate and tri-o-chlorophenyl phosphate.
