Title: Method of and apparatus for reducing or preventing the damaging effect of shorting between the workpiece and electrode in spark erosion machines
IPC: B23H1/02
Filed: 1958-05-09
Abstract: 856,251. Cutting by spark erosion. DEUTSCHE EDELSTAHLWERKE A.G., and ALLGEMEINE ELEKTRICITATS G.m.b.H. May 9, 1958 [May 15, 1957], No. 14980/58. Class 83 (4). A spark-erosion apparatus has the current supply to its working condenser 3 reduced or modified if a short circuit occurs between the electrode 4 and workpiece 5. In one embodiment alternating current is supplied from a source 8 through a transductor 9 and rectifier 10 for charging the condenser 3. If a shortcircuit occurs a relay 13 connected across the spark gap opens a switch 12 controlling a D.C. supply 11 to the transductor 9 to reduce the charging current. The switch 12 may consist of a thermionic valve or it may be a gridcontrolled rectifier forming the D.C. source. Where a rectifier is used as the D.C. source, the alternating current supply thereto may be interrupted in the event of a short circuit. In another embodiment, Fig. 1 (not shown), the switch controls a series resistance in a D.C. charging circuit. In another embodiment, Fig. 3, the switch 12 controls one phase of a three-phase supply to a bridge rectifier 14 and the modified current reaching the condenser 3 extinguishes any arcing due to the short circuit. In a further embodiment, Fig. 5 (not shown), the switch 12 controls a smoothing condenser on the output side of a full-wave rectifier. The spark-gap is bathed in a liquid dielectric. The electrode is fed automatically in response to the voltage across the spark gap.

Title: Electrostatic image reproduction
IPC: G03G15/18
Filed: 1954-05-21
Abstract: 772,873. Transferring electrostatic images. BATTELLE DEVELOPMENT CORPORATION. May 21, 1954 [May 29, 1953], No. 15064/54. Class 98(2) An undeveloped electrostatic latent image such as one formed on a xerographic plate is transferred to an insulating receiving surface by placing said surface in close proximity (i.e. an air gap of 2-90 microns) to the image-carrying surface and applying an electric field between the surfaces. The insulating surface may then be removed and the image thereon developed or used for a further transfer of charge to obtain an image which is not laterally reversed. As shown a transfer sheet of insulating material 20 is laid on top of a xerographic plate comprising a photoconductive layer 22 carrying an electrostatic image and supported on a conductive backing 21. An electric field is applied by a corona discharge from a grid of fine wires 23 held at a potential of several thousand volts with respect to the earthed channel 24. a control grid 25 being held at some intermediate potential. This device is moved back and forth over the back of the insulating sheet 29. The charge applied may be either positive or negative. Alternatively, the field may be applied by a conductive rod or roller connected to a source of potential and moved across the back of sheet 29. The insulating sheet may be of cellulose acetate, ethyl cellulose, polystyrene, polyethylene or insulating paper (i.e. of low moisture content). It is preferred to use paper sized with an insulating resin, or impregnated with ethyl cellulose, polystyrene, cellulose nitrate or cellulose acetate or paper coated on one or both sides with such plastic materials. The insulating sheet is preferably precharged prior to laying it on the photoconductive layer, and this is done by laying it on an earthed metal plate and passing a high voltage ion source over it. Either the face or the back of the sheet may be precharged. Improved results are obtained in the transfer step if an additional sheet is laid over sheet 29. This additional sheet may be of insulating material such as paper, cellulose acetate or polystyrene, but it is preferably conducting, as of metal, in which case the field may be applied by connecting a source of potential between the two conducting backing sheets, and the field may then be maintained while the surfaces are being separated. After transfer, the sheets are preferably removed as a unit and the image developed with or without the backing sheet., In a further embodiment, first an insulating sheet and then a conducting sheet are laid over sheet 29 during transfer. The sheet 29 with its backing layers may be precharged as described above. The transferred image may be developed by using a powder/carrier developer which is fixed by heating, or by blowing a charged powder or ink across its surface. The theory of the transfer in the various cases is fully discussed. Specifications 672,767, 679,715, 696,515 and U.S.A. Specification 2,346,812 are referred to.

Title: Improvements in and relating to solid aldehyde fuel and processes for the manufacture thereof
IPC: C10L5/40
Filed: 1941-12-01
Abstract: 572,765. Composition fuel. BATHER, J. Dec. 1, 1941, No. 15461. [Class 50] A solid fuel compressed into tablet form is made by mixing paraformaldehyde, or metaldehyde, or both, with a small proportion of a phenol-aldehyde condensation product, and with hexamine, the total aldehyde content being' greater than 50 per cent of the fuel. The condensation product is formed by the addition of from 2 to 10 per cent of phenol of the total aldehyde. The hexamine may be added as such, or by the addition of ammonia, or an ammonium salt, to convert the aldehyde into hexamine. A combustible natural or synthetic resin may be added to bind the product, for example oleo resin from the distillation of turpentine, or copal, pontianac, kauri or soft manilla resins, or resin's prepared from the condensation of a cyclic ketone with an aldehyde, or methyl cellulose may be employed. A lubricant may be added such as butyl stearate, triamyl borate, benzyl acetate, butyl acetate, furfural, ethyl glycol, or esters thereof, methyl-cyclohexanone, or diacetone alcohol, not exceeding 2 per cent of the total aldehyde content. Rubber latex may be used as a binder, but a lubricant such as lauric acid or paraffin wax should be added.

Title: Simultaneous image formation
IPC: G03G15/24
Filed: 1960-05-03
Abstract: 955,142. Xerographic apparatus. RANKXEROX Ltd. May 3, 1960 [May 7, 1959], No.15526/60. Heading G2H. An electrostatic electro-photographic process comprises the steps of causing a donor member bearing conductive toner particles to come into contact with a charged sensitized photoconductive layer on an earthed backing while a bias is established between the donor member and the backing such that no powder is transferred to the layer until it has been exposed. In the apparatus shown, a flexible xerographic plate comprising a transparent conductive backing member covered by a photoconductive insulating material is driven round rollers 57, 56 by a motor 58 and passes a corona discharge wire connected to a potential source 65 which sensitizes the plate on to which a light image from a cathode ray tube 40 is then directed via lens 51 and mirrors 52, 53 and through the transparent backing member. At the same point a pre-toned developer dispenser 66 which is transferred from roller 67 to roller 81 is pressed by roller 68 into contact with the plate 55. Roller 68 is conductive and is connected to a source 65 so that dispenser 66 is at such a potential that no electric field of force exists between dispenser web 66 and those areas of plate 55 which are still charged. When the dispenser 66 and plate 55 are peeled apart the image on the dispenser 66 which has a specular reflecting surface is projected by a light beam passing from lamp 73 through lenses 75, 76 on to screen 78 and the image is then permanently fixed by web 66 passing beneath fuser 80; the plate 55 is fed to a processing station 82 where the image may be transferred to paper or projected on to a screen. The dispenser 66 comprises a sheet of metal or a sheet of glass having a thin conductive coating on to which developer powder particles formed from metals or charcoal are sprayed, cascaded &c. IfX-rays &c. are to be used to form the image the conductive backing member of the plate need not be optically transparent. In another embodiment the dispenser may be in the form of a brush.
