IPC: B41M1/12
Filed: 1968-02-26
Abstract: 1,223,606. Electrostatic screen printing. CONTINENTAL CAN CO. Inc. 26 Feb., 1968, No. 9105/68. Addition to 1,120,052. Heading B6C. In an electrostatic printing apparatus for printing with toner upon a substrate and using screen stencil means for this purpose, means separate from those causing the toner to pass to the substrate through the screen are provided for neutralizing the electric field associated with the charged toner defining the image on the substrate. In the embodiment of Fig. 1, toner 22 is electrostatically forced through stencil 28 on to corrugated card 18. Corona discharge device 10 causes a stream of ions of opposite polarity to be directed to the non-printed side of the card 18 via grid screen control 20. In the embodiment of Fig. 3 printing is speeded up by charging the card 105 with ions of the correct polarity before moving the card-seen in position 100-to the printing location where corona discharge device 82 neutralizes the charge from the toner image on the underside of the card. In a variation of this embodiment the ions from the corona discharge device are directed in the precharge zone to the surface of the card which is to be printed. In the apparatus of Fig. 5 toner is directed through a belt stencil screen 148 on to a substrate 150 by corona discharge devices 144. The substrate is carried by a conductive conveyer 152 to the printing station through a cloud of positive neutralizing ions emanating. from a corona discharge device 154. In two further embodiments-Figs. 6 and 7 not shown-the ions issue from cylindrical corona generating chambers through which air is forcibly passed. The apparatus of Fig. 2 (not shown) is substantially identical with that shown in Specifications 1,120,051 and 1,120,052.

Patent GB-486347-A (GB)
Title: A process for treating ethereal oils with the aid of extracting agents
IPC: C11B9/00
Filed: 1937-04-01
Abstract: Essential oils are purified by extracting with two solvents which are not completely miscible and consisting of (1) oxygen-containing organic compounds preferably of low molecular weight, and (2) hydrocarbons preferably containing not more than 12 carbon atoms. The two solvents may flow in countercurrent through a stage extraction column, where the stages may be maintained at different temperatures, <PICT:0486347/III/1> the essential oil being introduced at the centre, or the oil may be dissolved in one solvent and the solution extracted with the other solvent.  Solvents of class (1) are methanol, ethanol, acetone, methyl formate, nitromethane.  These extract the desired component, e.g. the terpene alcohol, aldehyde, ester, aromatic aldehyde, ketone or phenol contained in the oil. Solvents of class (2) are propane, butane, pentane, aromatic-free gasoline, naphtha, lubricating oil, pentene, aromatic or hydroaromatic hydrocarbons.  These extract the terpenes.  The miscilibity of the solvents may be decreased by adding a small amount of water or by adjusting the temperature and pressure.  The formation of emulsions during extraction may be prevented by adding a small amount of citric or tartaric acid.  After separation of the two extracts, the solvents are recovered by distillation preferably under reduced pressure.  The oxygenated solvent may be recovered by washing the extract with water.  A horizontal extraction column 1, is divided by vertical perforated plates or sieves 2, to form a series of mixing zones 5 containing agitators 4, and settling zones 5.  Crude lemon oil is introduced at C, methanol at A, and light gasoline at G.  A temperature of 20 DEG  C., is maintained through the column.  The alcoholic extract is drawn off at Z and contains mainly citral, and the gasoline extract is drawn off at T and contains terpenes and sesquiterpenes.  In further examples, the following were treated (1) orange oil or ginger oil with 90 per cent methyl alcohol and pentane, (2) caraway oil with pentane and nitromethane, (3) lemon oil with methyl formate or acetone and gasoline.  Other oils which may be treated are lavender, rose, rosemary, onion, lime, jasmine, anise, acacia, or calamus oil.  Specification 355,294 is referred to. p

Filed: 1929-03-22
Abstract: 308,369. British Thomson-Houston Co., Ltd., (Assignees of Crawford, H. V.). March 22, 1928, [Convention date]. Regulating. - The power input to an electric motor 8 driving a centrifugal compressor 1 varies solely with the weight of air dis charged per minute and the air supply to the compressor is automatically con. trolled in accordance with the power input to the motor. The compressor 1 is shown connected by a discharge conduit 3 to a cupola 4, and its suction conduit 2 contains a blast gate 5 operated by an electric motor 7. This motor 7 is controlled by the switching device 11 which has an arm 12 normally equidistant from contacts 13, 14, but upon a variation of power input to the motor 8, the' arm 12 swings to touch one of the contacts 13, 14. If the resistance to flow through the cupola increases, the load on the compressor decreases and the input to the motor 8 lessens, thereby causing the switch 11 to close so that the motor 7 operates the blast gate 5 towards its closed position to bring the power input back to normal. If the cupola resistance decreases the gate 5 is moved towards its open position.
