Abstract: 258,223. Bosch Akt.-Ges., R. Sept. 11, 1925, [Convention date]. Supplying consuming devices from variable.-speed generators; regulation, automatic.-An automatic regulator and end in switch for a vehicle dynamo A and battery G. is formed with a single armature E supported by flat springs 5, 6 in a magnet casing D. Upon sufficient excitation of series and shunt coils 1, 2 by the dynamo A, the armature E moves to the right and transmits its motion through a spring 13 to a member H supported bv a flat spring 10, the member H moving against the action of a spring 14, which is weaker than the spring 13, until a contact 12 thereof abuts against a contact F and completes the circuit to the battery G through the series coil 1 and lead 17, In the position of the armature E, a resistance C in series with the dynamo field B, is shorted through lead 18, spring 5, armature E, flange contact 9, contact 11 of member H, and earth. Increase of voltage of the dynamo causes the armature E to move further to the right, thereby braking circuit at contacts 9, 11, and inserting the resistance C in the field circuit, and the apparatus functions as a vibration regulator. Should further increase of voltage occur, the armature E is moved so far that contacts 9, 12 engage thereby shorting the field 13 through the circuit, lead 18, contact 9, contact 12, leads 17 and 16.

Title: Improvements in the preparation of monoethers of poly-oxyalkylene glycols
Filed: 1942-10-31
Abstract: Ethers stated to be useful as lubricants for bearing metals, rubber and textiles and also as fluids for hydraulic transmission systems are obtained by reacting under anhydrous conditions a mixture of one part by weight of 1 : 2- propyleneoxide and from one to three parts by weight of ethyleneoxide with a monohydric alcohol.  The products are ethers of polyoxyalkyleneglycols having a polyoxyalkylene chain containing at least five oxyalkylene radicles.  Specification 443,559 is referred to.ALSO:Mono ethers of polyoxyalkylene glycols having a polyoxyalkylene chain containing at least five oxyalkylene radicles are obtained by reacting, under anhydrous conditions, a mixture of one part by weight of 1 : 2-propyleneoxide and from one to three parts by weight of ethyleneoxide with a monohydric alcohol.  Alkaline catalysts such as caustic alkali, morpholine or trimethylhydroxyethylammonium hydroxide and boronfluoride or mixtures of the latter with lime may be used in the process.  The catalyst should be removed at the end of the reaction.  In the case of caustic alkalies, these are neutralised with sulphuric or carbonic acid and removed by filtration.  The alkylene oxides may be dried and purified by distilling in the presence of solid caustic soda or potash or a glycol.  Excess of alkylene oxide is preferably avoided, a uniform concentration being maintained in the reaction zone.  In examples, ethanol, butanols and tetradecanol are treated with various proportions of mixtures of ethylene oxide and 1 : 2-propyleneoxide. In some cases, the product is worked up by extracting with hot water after removal of the catalyst and freeing from the lower boiling constituents. The products, which have foaming properties, are stated to be useful as lubricants, e.g. for textiles, rubber and metals and also for hydraulic transmission systems.  The treatment of wool, cotton, flax, hemp and synthetic fibres is mentioned. Specification 443,559 is referred to.

Abstract: 1458068 Making hollow glass articles PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 April 1974 [11 April 1973] 15478/74 Heading C1M Hollow glass articles are formed by severing gobs from a stream of molten glass using shear blades, shaping them into blanks using a mould and die arrangement, transforming the blanks on to moveable carrier plates each having an orifice through which the blank sags through the orifice where it is blown into its final shape, the mould and die moving so that their centre lines are always in a vertical plane which also contains the cutting point of the shear blades and is tangential to the path of movement of the centre lines of the orifics. As shown, the device for forming the glass articles comprises a cutting-shaping unit 3 and a blowing unit 5. The former includes a pair of shear blades 67 which are spring-biased and are operated by cam rollers 71 riding on a cam discs 73, 75. The blank shaping mechanism comprises a die 47 and a mould 48. The die 47 performs a linear movement only and this is brought about by a cam disc 83 acting through a lever 85 and air cylinder 81. The mould 48 performs both linear and rotational movements. To this end it is connected to a gearwheel 89 (Fig. 7) which is in turn meshed with a rack 95 and journalled in a sleeve 91 mounted on a moveable shaft 93. If the shaft and rack move together the mould performs a linear movement, if they move at different speeds a rotary movement is superimposed. The movement of rack and shaft is produced by cam systems including cam discs 105, 107. The cam discs driving the mould and die are driven by a worm gear, the worm having a shaft which is common to that of a worm gear driving the cam discs for the shear blades. The blowing unit 5 includes a rotary table 9 on which is mounted the carrier plates. These are slidable between an extended receiving position and a retracted blowing position.

Abstract: 1339929 Liquid crystal display devices RCA CORPORATION 19 May 1971 [27 May 1970] 15685/71 Heading G5C [Also in Division H4] A liquid crystal display device 50 has front and rear glass substrates 52, 58 respectively on which are deposited reflective layer 62, dielectric layer 64 and electrodes 70, 72, 54, between which is a layer 76 of liquid crystal material. The electrodes 70 and 72 have respectively the shapes of a circle and a square, and so illumination of the device from the front will, if a voltage is applied across electrodes 54 and 70, render the circle visible to an observer also disposed in front of the device. Similarly the square will be visible if a voltage is applied between electrodes 54 and 72. The layer 64 is thin to minimize the effect of the shadows cast by the electrodes 70, 72 on the layer 62. If the layer 64 is too thin, however, electrodes 70 and 72 may be shorted by the layer 62. This difficulty is removed in the embodiment of Fig. 4 (not shown), in which the electrodes 70 and 72 are connected by a conducting strip (94), and electrodes (90, 92) corresponding to 70, 72 replace the electrode 54. Separate voltages are applied to electrodes 90, 92. In alternative embodiments the layers on the inside surfaces of the substrates may be applied to the outer surfaces, provided that the order of layers on the rear substrate remains unchanged, the reflective layer 62 being the rearmost layer.

Title: Improved process and apparatus for the continuous production of esters of ethyl alcohol
IPC: C07C69/63
Filed: 1930-05-22
Abstract: Esters of ethyl alcohol with fatty acids, particularly acetic acid are obtained by leading the vapour mixture which passes off when de-spiriting mashes into a column system where successive esterification, removal of excess alcohol from the ester, and return of the unchanged alcohol are combined in a continuous process. Mineral acids or other suitable esterification catalysts may be present.  Dilute acetic acid, for example, raw pyroligneous acid from the fermentation of wood may be used.  Any methanol or higher alcohols present in the vapour mixture are converted to corresponding esters, which can be recovered by distilling the final product.  In one embodiment, mash enters a column 2 through a pipe 1, volatile constituents are separated, and, after passing through a dephlegmator, leave as vapour through a pipe 3.  If the mash contains large amounts of aldehyde, this can be separated by arranging a first runnings column behind the column 2.  The non-volatile impurities in the mash pass out through a pipe 4.  The vapours now flow through pipe 5a and 5b into an esterifying column 6 into which raw acetic acid, together with mineral acid if desired, flow from a container 8 through a pipe 7.  The ethyl acetate and other esters produced together with excess alcohol and water vapour leave through the pipe 9 and enter a washing column 10 into which hot water flows from a tank 11 through a pipe 12.  Ethyl acetate with any other esters formed leave as vapour through a pipe 13.  Waste water containing uncharged alcohol passes out through a pipe 14 into a de-spiriting column 15, into which also passes the outflow from the washing column 10 through pipe 16.  The vapour mixture of alcohol and steam with small quantities of ethyl acetate from the column 10 passes through the pipe 17 into the pipe 3 and is thus returned to the esterifying column 6.  The de-spirited liquors leave the column 15 through a pipe 18.  In another form, the columns 2, 15 having substantially the same function are replaced by a single column.  An example of the treatment of a sulphite liquor is given.
