Title: Controlling liquid electrophotgraphic developers
IPC: G03G9/135
Filed: 1972-03-23
Abstract: 1370526 Development of electrostatic latent images AUSTRALIA DEPARTMENT OF SUPPLY SECRETARY OF 23 March 1972 [25 March 1971] 13752/72 Heading G2H A liquid developer for electro-photographic images, of the kind comprising a dispersion of toner particles in a liquid carrier, is so constituted as to be neutral between positive and negative working, and to be turnable towards either of these by addition of an appropriate control agent. The developer comprises a paste of toner particles, such as carbon black, a metalorganic pigment, an inor or an organic pigment, with a resin coating insoluble in the liquid carrier, and is suspended in a carrier liquid with a resistivity in excess of 10<SP>10</SP>ohm. centimetre and a dielectric constant less than three. The carrier liquid may be a hydrocarbon, and the paste may include white spirit, methylene chloride, methyl ethyl ketone or dodecanol. A positive pigment, such as carbon black or copper phthalocyanine blue, may be milled with a strongly negative resin such as pentacrythritol resin or ethylhydroxy ethyl cellulose to produce the paste. Conversion of the neutral developer to positive development of a negatively charged image is brought about by addition of a material which wets the coated toner particles and dissolves in the carrier liquid. This material may be oleic acid, napthenic acid, zirconiumoctoate, an alkyd resin or a chlorinated diphenyl. Alternatively negative development may be brought about by addition of an organic oil. After one of these materials has been applied as a control agent to effect development, the developer may be returned to neutrality, or even the opposite sign. A developed image may be continuously scanned.  For example in colour development, and the developer modified automatically to correct the density of the image. Preferably the developer is used with a zinc oxide paper, comprising particles of photo-conductive zinc oxide in a film of insulating alkyd resin, bearing a negative charge image, but the zinc oxide may be replaced by selenium or a member of the sulphur group.

Title: New or improved resinous polyesters and method for their manufacture
IPC: C08G64/30
Filed: 1948-05-21
Abstract: Polyesters are produced by heating a mixture of a dialkyl carbonate in which the alkyl groups contain 1 to 6 carbon atoms and pentaerythritol, di-pentaerythritol, or a higher polypentaerythritol in the presence of an alkali metal alkoxide as catalyst with continuous distillation from the reaction mixture of the saturated monohydric aliphatic alcohol produced by the reaction.  Preferably the reaction mixture contains at least as many moles of dialkyl carbonate per mole of pentaerythritol, dipentaerythritol, or polypentaerythritol as there are primary alcoholic groups in the molecule of the latter reagent.  It is preferred to react pentaerythritol or di-pentaerythritol with four or six molar proportions respectively of the di-alkyl carbonate. The heating may be continued until as many molar proportions of saturated alcohol are distilled from the reaction mixture as there are primary aliphatic alcohol groups in the molecule of pentaerythritol, or stopped in which case the products contain unesterified alcoholic hydroxyl groups and may be reacted further, e.g. with di-isocyanates.  In examples: (1) pentaerythritol (1 mole) and diethyl carbonate (8 moles) are heated together with a solution of sodium ethoxide until 4 moles of ethyl alcohol has distilled off, glacial acetic acid is added, and the solution distilled, leaving a syrup soluble in acetone, chloroform, toluene, ethyl acetate, butyl acetate, and mixtures of alcohols and aromatic hydrocarbons.  Films of the product mixed with nitrocellulose on heating become hard and insoluble; (2) similar procedure to (1) is followed using dipentaerythritol (1 mole), diethyl carbonate (12 moles) and distilling off 6 moles of alcohol; (3) a syrupy resinous polyester containing about 5.5 per cent free hydroxyl groups is prepared by reacting pentaerythritol (1 mole), diethyl carbonate (5 moles) until 3.1 moles of alcohol has distilled off.  The product is mixed with hexamethylene di-isocyanate and baked at 100 DEG  C. to form an insoluble film.  The cyclic carbonate of 3 : 3-dimethylol-oxa-cyclobutane and diethyl carbonate are produced by treating the product of (1) with sodium ethoxide, heating it until it gels, and then heating the resulting solid in vacuo at 200 DEG  C.ALSO:Diethyl carbonate and the cyclic carbonate of 3 : 3-dimethyl-oxacyclobutane are obtained on heating with sodium ethoxide until solid, and then in vacuo at 200 DEG  C., the syrupy polyester obtained by reacting pentaerythritol and diethyl carbonate in the presence of an alkali metal alkoxide (see Group p  IV (a)).

Title: Light signal apparatus for light buoys and the like
IPC: B63B22/16
Filed: 1941-10-29
Abstract: 579,730. Signalling by visible signals. GAS ACCUMULATOR CO. (UNITED KINGDOM), Ltd., and DORTON, E. W. Oct. 29, 1941, No. 13921. [Class 118 (ii)] Relates to gas-operated signal apparatus particularly intended for light buoys but applicable also for timing gas-operated apparatus such as bell-tolling mechanism. According to the invention, apparatus for giving single flashes is adapted to give groups of flashes by mechanism which automatically and periodically alters the rate of flow of the gas supplied to a singleflashing apparatus. The apparatus comprises a burner 20 to which gas is supplied by a pipe 9 through a singleflash apparatus 18. The device for altering the rate of flow of gas through the pipe 9 comprises an upright chamber 1 connected to the burner conduit 19 and having its lower end formed by a diaphragm 2 which is pressed upwards by a spring 3. Arranged above the chamber 1 is a smaller chamber 4 sealed by a diaphragm 5 carrying a valve 6 that co-operates with the end of the pipe 9. An inlet pipe 7 leads gas into the chamber, and a pipe 8<1> bypasses the valve 6 and is controlled by an adjustable throttle 10. The diaphragm 2 supports a rod 11, a pawl 12 for operating a ratchet wheel 14, and a stop member 13 which makes contact periodically with a coding wheel 15 secured to the ratchet wheel 14. In use, gas from the pipe 10 passes through the chamber 4 and thence through the single-flash apparatus 18 to the burner 20. The gas also enters the chamber 1 and lowers the diaphragm 2 moving the coding wheel 15 to a new position. Immediately the gas supply is stopped by the device 18, the diaphragm 2 rises but the movement is stopped by contact of the member 13 with the edge of the wheel 15. If, however, the end of the member can enter a slot 17 on the wheel 15, the rise of the diaphragm is sufficient for the rod 11 to close the valve 6, thus cutting down the supply of gas to the device 18 and increasing the time before the burner 20 flashes again. The position of the slots 17 in the wheel 15 regulates the sequence of flashes. The gas valve may be inverted in action so that the pressure of the incoming gas on the associated diaphragm causes the gas valve to close. In another arrangement, the main diaphragm is operated by the cyclical variation in gas pressure within the singleflashing apparatus, or the gas pressure may be applied to the underside of the diaphragm in the main chamber.
