Title: Improvements in or relating to separating apparatus particularly for the separation of liquids from gases
IPC: F01M11/08
Filed: 1928-10-30
Abstract: 324,656. Eyston, G. E. T. Oct. 30, 1928. Density separators.-A separating apparatus, particularly for the separation of liquids from gases, has a duct formed by rings b supported in an outer casing a by radial flanges d. Sets of fan or propeller vanes l are mounted on ball bearings m on a spindle n supported by spiders o in the inlet and outlet ends g, h. The gas to be cleaned is led under pressure to the inlet g and in its passage to the outlet h causes the vanes l to rotate, thereby throwing any liquid particles from the gas stream outwards into the space t between the rings b and the casing a. The flanges d are perforated so that the liquid runs down to the outlet u. The area of the open space between the propeller blades l of each set is substantially the same as the cross-sectional area. of the inlet. A gas outlet 2 may be provided at the top of the space t to permit a small quantity of gas to pass from the blades with the liquid. In the modification shown in Fig. 3, the blades l work inside a tube v provided with perforations w. Rings x of inverted truncated conical form are fixed above the sets of blades, and thrust bearings z are also added. The gas passes upwards; the liquid particles are thrown to the wall of the tube v and then pass through the perforations w to the outlet u. The rings x prevent any rapid passage of the gas at the tips of the blades l and so the separated liquid is not entrained. The rings may be partly made of wire gauze or like material. The blades l may be perforated, and a cone 1 may be used to direct the gas over the bearings.

Filed: 1972-07-05
Abstract: 1386847 Electrostatic and magnetic printing PELOREX CORP 5 July 1972 [16 July 1971] 31505/72 Heading G2H [Also in Division B6] In a copying press a developed electrostatic image is used to form an identical magnetic image either beneath the electrostatic image or on a tape or member, which is brought into contact with the electrostatic image. In the apparatus of Fig.1 a  magnetizable endless band 12 is charged by means 21, imaged by lens 20 and developed with suitable toner particles of iron and resin in a bath of kerosene and water 25. The developed image is magnetized by magnet 30 and demagnetized by magnet 38 the toner particles of the image acting as a shield and preventing demagnetization of the band beneath the image. The image is transferred to a copy web 11 whilst passing through rollers 45 and 13 and the image is heat fixed by means 48. If the magnetic image is to be used for multiple copies a further demagnetizer 50, band cleaner 58 and the charging and optical means 21 and 20 are deactivated whilst band proceeds to follow a continuous endless path. When a new image is desired the demagnetizer and cleaner 50, 58 are energized. In a modification of this embodiment Fig.8 (not shown) the band 12 is a drum 103 and the magnetic image is formed on an endless band 107. In Fig.9 (not shown) multi-coloured reproductions are made three separate devices such as that shown in Fig. 1 being employed each for a different colour, blue, yellow or red. Fig.10 also shows a multi-colour reproducer the three electrostatic images on endless band 180 being converted to three magnetic images on band 194 and the copy feed drum 201 revolving at three times the speed to collect the full superimposed colour reproduction. In the apparatus of Fig.15 5 the copy web 252 is electrostatically imaged and developed and fixed and an endless band 262 is used to produce and transfer a magnetic image derived from the electrostatic image back to the web 252 but spaced from the original electrostatic image. Fig.20 (not shown) is similar to the apparatus of Fig.15 but the developer is applied using permanent or electric magnets.

Title: Image forming apparatus and method
IPC: G06K15/14
Filed: 1958-10-02
Abstract: 901,533. Printing processes. RANKXEROX Ltd. Oct. 2, 1958 [Oct. 2, 1957], No. 31547/58. Class 100 (2). In a method of recording characters, an insulating layer, having its surface coated with electroscopic material, is placed with its coating against an image-receiving surface and an electric field is applied in image configuration so that a quantity of electroscopic material in corresponding image configuration is transferred to the receiving surface. The field is produced between a character face and a plain electrode. The character face is spaced from 2 to 250 microns from the adjacent layer, which may be the insulating layer or the receiving surface, and the field strength is from 6 to 40 volts per micron. The field produced between the type slug 13, Fig. 1, and the electrode 14 by the battery 16 is insufficient to transfer the material 15 from the layer 12 to the surface 11, but when the switch 17 is closed, an additional pulse from the battery 18 causes transfer. Alternatively, on depressing and raising a contact arm 20 while the contact arm 9 is in the opposite position to that shown, a condenser 21 is first charged, and then discharged through the primary of a transformer 23, producing a transfer pulse in the secondary. In another form, Fig. 2, the receiving surface is a web 11 fed from a roll 42 between a series of electrodes 36 and a rotatable cylinder 32 of dry paper, plastic, or other insulating material carrying electroscopic powder coated thereon by a brush 40, and past an image-fusing hot plate 43. Independently rotatable within the cylinder 32 is a conductive drum 30 including a plurality of axially-spaced annular rings each bearing in relief the letters of the alphabet and the numerals, the drum 30 being rotated one revolution for each line-space feed of the web. Rotating with the drum is an iron disc 35 having a series of slots, or a disc carrying a series of magnetic spots, the slots or spots corresponding to the characters and which in passing a magnet 125 causes a pulse to be passed to an input storing circuit 122, which also receives a character signal from a computer through a condenser 121. When the required character is passing the electrode 36, there being an electrode and pulsing circuit for each character ring, the correspondence of the signals from the conductors 123, 121 causes a pulse to the grid of a triode 119 and a transfer pulse to the corresponding electrode 36. A second disc having one magnetic spot may be provided as a drum revolution counter. Alternatively, the insulating layer may be a web pre-coated with electroscopic material, fed between rolls and between the web 11 and the drum 30 being supported on discs at the ends of and slightly larger than the drum. Specification 734,909 is referred to.
