Title: Fixing of deformation images in electrostatic recording
IPC: G03F7/26
Filed: 1964-05-13
Abstract: 1,61,235. Electrophotographic methods. RANK XEROX Ltd. May 13, 1964 [June 3, 1963 (2)], No.19895/64. Headings G2C and G2H. In a method of image recording in which an image is formed by electrostatic deformation of a deformable layer, the layer is permanently hardenable by exposure to actinic radiation and selected areas of the layer are radiation-hardened to prevent subsequent electrostatic deformation in those areas. The electrostatic image charge is applied to the film or layer which is then softened by heat or by solvent vapours to allow "frosting" by the image charges. The layer is then hardened by cooling or removing the vapour, and permanently hardened by exposure to electromagnetic radiation of ultraviolet wavelength, or of visible wavelenghts when a sensitizer is used in the layer; beta-rays also are mentioned. In an alternative system, the layer is exposed to a radiation image pattern for selective hardening, a uniform charge is applied, the layer is then softened as above for frosting and hardened as above. Again, the film may be supplied prefrosted for exposure to an image in hardening radiation, whereafter a softening process subsequently erases only the non-exposed areas; the film is then hardened. The charge patterns are applied as in Specification 1, 049, 881. The layer is electrically insulating at its melting point, is solid at room temperatures and is irreversibly hardened by actinic radiation; it is also preferably thermoplastic. The frostable materials may be mixtures of photo-polymers and frostable resins. Examples of material include Staybelite Esters, Pentalyn -H, Velsicol EG - 11, KPR or Kodak Photo-resist, and Piccolastic A-50 with KPR, all being Trade Names. In an apparatus shown, the layer or film is backed by a conducting grounded plate, or it may be formed on a grounded metal foil. The permanent exposure hardening is said to be due to cross-linking of polymers, polymerisation of small molecules, intermolecular bridging of large molecules, whereby the average molecular weights is raised. Such materials may contain the ethylenic linkage ( > C = C < ) sensitive to ultraviolet light. A partially hydro-genated rosin ester containing dihydroabietic acid plus a further resin consisting of a triethylene glycol ester of partially hydrogenated rosin are mentioned, also a rosin pentaerythrital tetraester and a terpolymer formed from styrene, indene and pentaerythrital isoprene monomers. Further suitable materials include the cinnamate esters of polyvinylalcohol and of cellulose, sensitized by anthrones and their derivatives, polynuclear quinone derivatives and ketones such as Michler's ketone.

Filed: 1971-06-10
Abstract: 1351863 Digital data encoding HONEYWELL INFORMATION SYSTEMS Inc 10 June 1971 [6 July 1970] 19983/71 Heading G4C A digital encoder translates an NRZ data input W into a self clocked three frequency output F5, e.g. for storage on a magnetic storage medium F5. The output data has a flux reversal in the centre of every bit cell containing a binary 1 and a flux reversal between two adjacent bit cells containing binary zeroes. The data W is gated from shift register 100 by pulses # 2  from a two phase clock 10 (Fig. 1a, not shown) to a first flip-flop 20. The pulses # 2  occur at the boundaries between bits. It emerges delayed by one bit as waveform W1 which is fed to NAND gate 26 to pass pulses # 1  from the two phase clock when there are binary 1's in waveform W. The pulses # 1  are at the centre of the information bits. A second flip-flop 30 is fed with W+W1 via NAND gate 24 and inverter 22. The complemented output F1 is fed with # 2  to NAND gate 32 whose output F2 has pulses when there are successive binary zeroes in the waveform W. F2 and F3 are passed to NAND gate 34 which feeds a complemented bi-stable circuit 40 to produce the final output F5. The encoder may be made as an integrated circuit using MOS logic.

Abstract: A siloxane having the formula <FORM:0994397/C3/1> where R and R1 are each a monovalent hydrocarbon or halohydrocarbon (saturated or unsaturated) radical, a has a value of at least 2 and b is 2 or 3, can be made either (i) by hydrolysing and condensing a mixture of R1SiCl3, R2SiCl2 and R2Si(Cl)CbH2bCN, o (ii) by forming a reaction mixture of phenyltriethoxysilane, octamethylcyclotetrasiloxane and 1,3-bis(betacarboxyethyl)-tetramethyl-disiloxane and heating this mixture in the presence of conc- H2SO4. In a typical example (1) water was slowly added to a mixture of CH3SiCl3, (CH3)2SiCl2\t and (CH3)2Si(C3H5CN)Cl, with subsequent remova of H2O and HCl by stripping, followed by removal of NH4Cl by filtration, and drying; the resulting reaction mixture was then equilibrated by heating with H2SO4.  Uses.-As emulsifying agents, e.g. in making aqueous emulsions of siloxane liquids; as alcohol base cosmetics; and for making siloxaneesters as described in Specification 994,396.  In Example 5, the carboxy-propylsiloxane of Example 1 was reacted with a monobutyl ether of a mixed poly-oxy-ethylene-poly-oxy-propylene-1,2-glycol in the presence of p-toluene sulphonic acid to form the corresponding siloxane ester, which was mixed with a triol of molecular weight and formed by reacting propylene oxide with glycerine, stannous octoate, a diisocyanate mixture (80% by wt. of 2,4- and 20% of 2,6-toluene diisocyanate), triethylene diamine, N-ethylmorpholine and water, to yield a flexible polyurethane foam having small uniform cells.

Abstract: 579,254. Winding bobbins. VANDERHOOVEN, C. C. Dec. 1, 1943, No. 20110. Convention date, June 26, 1942. [Classes 120 (ii) and 120 (iii)] Rayon is wound into a cylindrical permeable, cross wound package with self-supporting square ends and radial channels, by apparatus having a traverse member of constant stroke to produce a pattern wind and means for intermittently circumferentially displacing successively wound portions of the pattern. The shaft 21 is driven from any suitable power source which may include any variable speed transmission to progressively decrease the bobbin wind during winding. Each foraminated bobbin 10, carried by a bobbin holder 14 is driven from the shaft 21 by a shaft 15. The shaft 21 also drives the traverse cam 13 through a gear train including a tripping coupling so that periodically the traverse cam is not rotated but the bobbin continues its rotation. The tripping coupling comprises a disc 40, keyed to the shaft 41 carrying the traverse cam 13, which is rotated through pawl and ratchet mechanism 38, 39. In rotating, the disc 40 carries around with it a star-gear 78 which contacts a pin 92 on the machine frame to rotate a worm 84 which advances a gear train to lift, periodically, the driving pawl 39 from the wheel 38 so stopping the traverse cam shaft 41 from rotating. A further pawl 94 and ratchet wheel 74 prevents the disc 40 from turning ahead of the ratchet wheel 38. The traverse bar 12, supported by plates 62, is operated from the traverse cam 13 by link and rock shaft mechanism. The thread guide 69 is of the self-threading kind, furnished with a thread slot 70 and supported by the bar 12 by a pin 72. The thread is guided on to the package by the tines of a fork 67, pivoted at 65 to the traverse bar and urged against the package by a counterweight 68.
