Title: A lithographic offset printing machine
IPC: B41F31/02
Filed: 1960-12-21
Abstract: 954,510. Inking and damping-mechanisms. P. A. GLATZ. Dec. 21, 1960, No. 43875/60. Heading B6C. A lithographic offset printing machine has an inking fountain which has an outlet aperture closed by a roller carried by the fountain and which on rotation removes ink from the fountain and transfers it directly to the plate cylinder, means being provided for controlling the volume of ink applied to the roller. The fountain 1, Fig. 4, is supported in a metal segment 20, and its outlet is sealed by an inking roller 7 which applies ink directly to the plate cylinder 8. The roller 7 co-operates with a duct blade 22 or an equivalent roller. The roller 7 is pressed against the cylinder against springs 9 by an arm 2 which supports the fountain and is controlled by a hand-lever 4 movable to allow the fountain to move upwards. The ink in the fountain 1 is pressed down by a plate 18 moved stepwise downwards by a mechanism driven from the printing-machine and including a crank-rod 12, pawl 14, ratchet-wheel 15 and rack 17. In another form, Fig. 5, a plastic ink container 28 is supported in a metal segment 29 and the sealing roller 30 co-operates with an adjustable duct blade 31. A recess in the fountain accommodates a damping pad 37, and the fountain, while in its upward position, is swung about a pivotal support through an angle 42-40 to bring the damping pad against the plate 41. The fountain is interchangeable, being removed by lifting its bearings through vertical slots in the metal segment.

Title: Image Intensifier

Filed: 1967-09-28
Abstract: 1,198,464. Electroluminescence. XEROX CORP. 28 Sept., 1967 [29 Sept., 1966], No. 44129/67. Heading C4S. A radiant energy amplifier comprises an electroluminescent phosphor 17, a field effect semi-conductor 14, at least two energizing electrodes 16 on one side of the f.e.s.c. the phosphor and f.e.s.c. being arranged so that current passing between adjacent electrodes through the f.e.s.c. also passes through the phosphor, a power supply 18 connected across said electrodes, a photoconductive insulating layer B adjacent a free surface of the f.e.s.c. a thin insulating layer 15 between the f.e.s.c. and the p.c. layer and means 12 for applying a potential to the p.c. layer at a portion remote from the f.e.s.c. With no incident radiation the voltage from the supply 18 is either sufficient to cause material 17 to glow or it remains dark. When incident radiation 21 falls locally the resistance of the p.c. layer 13 locally decreases allowing charge from conductive layer 12 connected to source 19 to move towards the insulating layer 15 and induce an opposite charge on its other surface adjacent the f.e.s.c. 14. This alters the resistance of the f.e.s.c. and results in variations in current flowing through the c.p. layer which produce a positive or negative image. A weak signal can be integrated since the charge continuously builds up across the layer 15. The image is erased by grounding layer 12 or applying an opposite potential and flooding with light. Alternatively a potential is applied to layer 12 whilst it is flooded with light. When this is stopped a charge is trapped at the layer 15 and an image of incident light is produced by grounding layer 12 during exposure. Incident radiation may be X-rays, infra-red U.V. and visible light. A.C. or D.C. potential may be applied between the electrodes 16. Layer 12 may be removed from the P.C. layer after exposure or it may be replaced by a corona discharge generator In another embodiment the e.l. material forms a continuous layer over the electrodes, current flow between adjacent electrodes being prevented by keeping the impedance high. The e.l. material is ZnS activated by CuCl 2  and Mn. The f.e.s.c. is Si, Ge, CdS, CdSe or ZnO. The photoconductive material is S, Se, AsS, PbO, PbS, ZnS, CdS, Cd sulphoselenide polyvinylcarbazole, phthalocyanine or a quinacridone, either homogeneous or particulate in a binder with dopants and sensitizers.

Title: Sulphur-containing organo-tin compounds and stabilising polyvinyl chloride compositions therewith
IPC: C08K5/58
Filed: 1962-11-22
Abstract: The invention comprises organo-tin compounds of the formula <FORM:0990592/C2/1> where R is tertiary butyl or nonyl and R1 is an alkyl group preferably of 1 to 18 C atoms, aryl e.g. phenyl or aralkyl e.g. benzyl.  Specifically disclosed, with methods of preparation, are diethyl, dibutyl, didodecyl, diphenyl and dibenzyl tin bis (p-tert. butyl phenyl mercaptide) together with dibutyl tin bis (p-nonylphenyl mercaptide).  Also disclosed are the disubstituted tin bis (p-tert. butylphenyl mercaptides) wherein the substitutent is phenyl, benzyl or an alkyl group from methyl to octadecyl.  The method of preparation may be by the reaction of a dialkyl tin oxide with a thiophenol with subsequent removal of the water of reaction by azeotropic distillation with the solvent used in the reaction e.g. toluene.  In an example, p tert. butyl thiophenol and diethyl tin oxide are boiled under reflux in toluene solution and the water removed as the toluene azeotrope.  The solution is then filtered and the filtrate concentrated in vacuo to give diethyl tin bis-(p tert. butylphenyl mercaptide.  Compositions containing polyvinyl chloride are stabilized by the addition of these organo-tin compounds (see Division C3).ALSO:Polyvinyl chloride compositions are stabilized by the addition of a minor amount (0.01 to 10% wt.) of an organo-tin compound of formula <FORM:0990592/C3/1> where R is tertiary butyl or nonyl and R1 is alkyl, e.g. 1-18 C atoms, aryl, e.g. phenyl or aralkyl, e.g. benzyl.  In specific examples both dibutyltin-bis-(p-tert.-butylphenyl mercaptide) and the nonyl derivative are shown to be effective at 190 DEG  C. in P.V.C. compositions. Diethyl, didodecyl, diphenyl and dibenzyl bis(p-tert.-butyl phenyl mercaptides) may also act as stabilizers. For the preparation of these compounds see Division C2.
