Abstract: 1,242,095. Printing apparatus. L. KELLER. 20 Aug., 1968 [21 Aug., 1967], No. 39792/68. Heading B6C. The temperatures of ink and dampening substance applied to lithographic forme cylinder 8 by inking and dampening apparatus 6, 7 are independently regulated by means incorporated in the two supply systems. For example the temperature of dampening substance supplied from trough 22 by fountain roller 24, messenger roller 25 and rollers 24<SP>1</SP>, 26 may be regulated by circulating the trough contents through container 45, which contains a cooler 44, actuated by temperature-sensing device 49 when the temperature of the circulating dampening substance exceeds a preset value. Similar recirculation and cooling may be applied to water circulating within rollers of the inking apparatus 6, and if the roller train of the inking apparatus branches separate temperature regulation may be employed in the branches. Roller 20 may be held at a lower temperature than roller 21, for example, and the dampening substance supplied from trough 22 be cooler than either. Temperature regulation may be obtained or extended by regulating the temperature of other rollers of inking apparatus 6, such as forme rollers 31-34, or by regulating rollers of the dampening apparatus 7, such as roller 24.

Title: Duplicating
IPC: B41M5/26
Filed: 1964-10-06
Abstract: 1,059,659. Printing processes. XEROX CORPORATION. Oct. 6, 1964 [Oct. 7, 1963], No. 40698/64. Heading B6C. A method of duplicating comprises positioning between the faces of two master members 42, 43, Fig. 4, an original sheet 41 bearing images on each of its two sides, said images being of a coloured marking material containing a transferable component, transferring at least a portion of the image material on each side of the original sheet to the face of the master sheet facing it by passing the assembly between heated rollers 45, 46, removing the sheet 41 from between the master sheets and replacing it with a copy sheet, Fig. 6 (not shown) treated with a colour reaction partner for the image material, and passing the new assembly between the heated rollers whereby a two-sided duplicate of the original sheet 41 is obtained. The master may be of a plastics material, metal foil, glass or paper and the original, which is preferably of bond paper, may be imaged with a material containing a chemical such as rubeanic acid by a typewriter, a stylus device, or xerographically. The heat of the rollers 45, 46 causes a portion of the volatile colour reagent to evaporate or sublime between the surfaces of the master sheet and the original. The heat may be supplied by photo-flash lamps, infra-red lamps, hot air blowers, or by electric resistance devices. Examples are given of suitable chemical reaction partners for the image on the original and the treatment of the copy sheets. Printing surfaces.-In the embodiment of Fig. 7 two co-operating rollers 50, 51 carry metal, polytetrafluoroethylene or glass layers 56, 57 and on passage of an original between the rollers an infra-red source 65 causes the transfer of some of the image from each side of the original on to the respective layer. Copy sheets from a feed tray 67 are then run off into a, receiving tray 68. Each roller is provided with a retractible cleaning device 58 comprising a container 60 for a solution 61 which is a solvent for the original image material, a brush 62 and a doctor blade 63. In a further embodiment, Fig. 8 (not shown), the rollers are replaced by heated dispensible endless belts of paper or by permanent polyethylene terephthalate belts coated with polytetrafluorethylene. The original and/or the copy sheet may be presented to the heated device as a laminate which is subsequently separable into two sheets.

Title: Improvements in and relating to pads of rubberised hair and methods and apparatus for the production thereof
Inventor: HOWARD HAROLD ARTHUR
IPC: D04H1/64
Filed: 1960-12-01
Abstract: 938,260. Agglutinated fibrous sheet materials; needling. HAIRLOCK CO. Ltd. Nov. 24, 1961 [Dec. 1, 1960], No. 41324/60. Class 42 (2). In a pad of compressed rubberized hair, i.e. upholstery fibres such as horsehair, wool, coconut fibre, Algerian grass or polyamide filaments coated with an adhesive remaining flexible when dry such as rubber latex or plasticized polyvinyl chloride, having two substantially plane faces parallel to each other, the hairs extend multi - directionally between the plane faces with a sinuous grain resulting from lateral compression, in a direction substantially parallel to the plane faces, applied at closelyspaced intervals, indicated by the arrows in Fig. 2, within the thickness of the pad during manufacture thereof and before the setting of the adhesive. Apparatus for the batch production of the pads comprises multiple-slotted plates 7, 8 and needles 15 held by bars 14 slidably mounted by sleeves 13 on two pairs of rods 12, the sleeves 13 alternating on the rods 12. The bars 14 are linked together in pairs by slotted links 16. Beams 17 also slide on the rods 12 and are connected by links 18 to the respective end bars 14. Each beam 17 carries a rack 19 to mesh with a pinion 20 driven by a motor 23. A sheet of hair coated with adhesive is placed on the plate 7 which is then raised by a jack 9 and lifts the plate 8 resting on distance-pieces to suit the pad thickness placed thereon. The needles 15 pass through the slots in the plates. The motor 23 is actuated and the beams 17 move inwardly to abut the end bars 14 which then move successive bars inwardly until the bars 14 are closed towards the centre. Plunger locks 11 are protruded to engage the plate 8 and the plate 7 is lowered leaving the sheet 24 on the needles 15, Fig. 8. An open rectangular frame 25 is placed on the plate 7 in alignment with the sheet 24 and the plate 7 is raised so that the frame surrounds the sheet. The locks 11 are retracted and the plates 7, 8 are lowered until the plate 8 contacts supports 10. The adhesive of the sheet is vulcanized or set whilst it is held in the frame 25. In an alternative embodiment (not shown) for the continuous production of pads, needlebars are mounted on slats of an endless conveyer and are moved into a web moving on a conveyer between slotted parallel plates so that the needle slats move with, and successively close up on one another in, the web until the adhesive has set. In a modification at least one pair of sets of needles is caused repeatedly to penetrate the web and one set is relatively moved laterally towards the other for a short distance and then withdrawn. The needles may be mounted on parallel bars one or both of which is or are reciprocated. The needles of each pair may penetrate the web from one side or opposite sides thereof.

Title: Improvements in the production of electrostatic charge patterns
IPC: G03G15/056
Filed: 1961-11-24
Abstract: 1,001,546. Electric digital data stores; electrostatic recording. L. E. RAVICH. Nov. 24, 1961 [Nov. 25, 1960], No. 42065/61. Headings G4C and G5R. [Also in Divisions G2 and H1] A charge pattern is produced on a layer of photo-conductive insulating material by illuminating it with light to produce free charges and then separating the charges by an alternating electric field to provide a positive charge pattern on both faces. For instance the sheet may be illuminated in a pattern and the charges separated by a uniform or non-uniform field, or the sheet uniformly illuminated and the charges separated by a non-uniform field. Another possibility is to uniformly illuminate, apply a uniform field and then locally remove the charge on one or both faces by shining a pattern of light on it with the faces externally short-circuited to produce a negative image. If the light is heavily absorbed by the sheet the image appears only on the illuminated face, in which case a different image can be formed on the opposite face. Otherwise the same pattern appears at both faces. A negative image may alternatively be obtained by locally recombining the free charges produced in a first uniform illumination by illuminating again with a pattern of infra-red light before the alternating field is applied. The stored information may be read off by mechanically scanning a probe over one face of the sheet as illustrated in Figs. 4 and 5 (Fig. 4 not being shown). The probe connects the element in a series circuit including a resistor the voltage across which is amplified and then displayed on a cathode-ray tube. In the digital storage system shown in Fig. 8, the information is fed in in one of the above ways as a scanning light beam from cathode-ray tube 70 which is switched on or off in accordance with the information to be stored at a particular point. After separating the charges by an alternating field information can be read out by scanning with a uniform intensity light beam, the amplified information read out being displayed on cathoderay tubes 92, 86 synchronized with the scanning tube. Information may alternatively be fed in by a uniform intensity scanning beam projected through a patterned mask. In a modification of this system using an insulating sheet with sets of mutually perpendicular electrodes on opposite faces electronic switching is used to apply the separating field in accordance with signal information only to selected areas of the sheet. In this case charges are separated only at areas which are illuminated and subjected to the field. It is also possible to subsequently illuminate. with a further information containing pattern with the electrodes externally shorted to erase some of the information thus stored. Specification 672,767 is referred to.
