Abstract: Lithographic dampener of the type having continuous plate/form roller/metering roller (14,35,45) contact, adaptable to a variety of press configurations and operating speeds, employs a friction-driven oscillator roller (65) which distributes added dampening liquid and the ink/liquid emulsions on the metering roller (45), to avoid continuing patterns which might cause ghosting in printed images. The dampener has a simple drawer-like configuration, with an open front for improved range of form roller/plate contact. A pan (40) with a remote supply of dampening liquid, is located under the rollers (35,45,65) such that the metering roller (45) surface contacts and picks up liquid from a pool in the pan (40). Simplified seal dams at the ends of the form/metering rollers' nip keep the reservoir of liquid in that nip, yet minimize wear of the seal configuration. A slide block mounting (50B) of the metering and oscillator rollers (45,65) allows independent adjustment of pressure at the form/metering rollers' nip, and at the metering/oscillator rollers' nip.

Abstract: A specially coated paper which has been prepared for imaging in an electrophotographic reproduction process, and a method for developing an image produced on this paper so that it may be used as a lithographic printing plate. The base material is polyester and is coated with either a thermoplastic or cross-linking resin or mixture of resins. The layer which is used for coating the polyester is loaded with zinc oxide. Once the printing plate has been prepared, it is then imaged in a photocopier or laser printer using the indirect electrophotographic process. Background dots can then be eliminated by application of a specific mixture to the printing plate before printing. The mixture preferably consists of an emulsion with an external hydrophilic phase, and an internal lypophilic/solvent phase held together by a surfactant or mixture of surfactants. Optionally, the external phase may also contain an aqueous solution of ferrocyanide or tannic acid or any other known conversion agent so that it may be applied to the plate without the need for previously etching it with the conventional electrostatic conversion etch. The plates may be imaged in laser printers, so that printing plates may be obtained directly from both digital and analog information on equipment that need not be dedicated to such use, which is already owned by potential users.

Abstract: Coextrusion apparatus for varying the inner profile of a generally tubular extrudate formed by a first stream of elastomeric material, by an axially movable inner die ring which varies the size of an orifice and consequently the flow of a second stream of elastomeric material which is deposited on the inner surface of the tubular extrudate. A compensating ring is axially slideably mounted within the inner die ring and moves generally in an opposite direction to the movement of the die ring to compensate for pressure changes within the second stream of material caused by varying the size of the orifice, to provide an accurately controlled initiation and termination of the material. Concentrically mounted pressure actuated piston rods control the movement of the inner die ring and compensation ring. The orifice for the second stream of elastomeric material is located slightly downstream of the orifice for the tubular extrudate and extends in a generally radial direction. A reinforcing guide directs a plurality of fiber-type reinforcing elements into the tubular extrudate prior to depositing the second stream of elastomeric material on the inner surface thereof. A method for varying the inner profile of the interior surface of a tubular extrudate is also presented.

Abstract: The invention provides novel aqueous solutions of adhesive which do not contain any organic solvent. These solutions are completely clear and exhibit the perceptible tackiness so beloved of consumers. As active adhesive component the solutions contain copolymers of acrylic acid, vinyl acetate and a monomeric surfactant copolymerisable therewith which has been selected from among certain types of compounds. One of the selected types of compounds is a polyoxyethylene allyl alcohol (polyoxyethylene glycol allyl ether) of the following formula IA <IMAGE>  or its methyl ether of the following formula IB <IMAGE> where n is from 2 to 50. The adhesive solutions are simple to prepare by starting with an aqueous solution of a surfactant and adding partially NaOH-neutralised acrylic acid in the form of an aqueous solution and also the vinyl acetate with or without a further ethylenically unsaturated comonomer in the course of a few hours. The reaction is advantageously carried out at from 70 to 85 DEG C. At relatively high monomer concentrations it is possible to include in the reaction batch molecular weight regulators, such as polyglycols and/or acetates thereof. In this way it is possible to adjust the solids content of the adhesive solution to a desired value in a simple manner.

Abstract: A polyimide film is described having improved adhesion prepared by coating the surface of a partially cured or partially dried polyamide acid film with an organic solvent solution of a metal salt and heating the coated film to both convert the polyamide acid to polyimide and dry the film. By proper selection of the metal salt from the group consisting of Sn, Cu, Zn, Fe, Co, Mn and Pd, either a one-side adherable or two-side adherable polyimide film can be obtained. The polyimide film can be used in electrical insulating and flexible printed circuit applications where superior adhesion is an important requirement.

Abstract: A low voltage monitor and microcontroller output monitoring circuit for insuring proper operation of a microcontroller in a furnace control system. A switch connected to a reset port of the microcontroller is capable of putting either a high or low voltage signal at the reset port. A high signal is required for normal operation of the microcontroller. The low voltage monitor connects to a power supply providing power to the microcontroller and causes the switch to provide a low signal to the reset port if the output voltage of the power supply drops below a predetermined level. The output monitoring circuit insures that the microcontroller is operating properly by insuring that the microcontroller is producing an output signal at a predetermined frequency and repetition rate. If the output signal is not at the predetermined frequency, the output monitoring circuit causes a low voltage to be present at the reset port.

Abstract: Aromatic hydrocarbons are produced by catalytic conversion of aliphatic hydrocarbons using an aluminogallosilicate catalyst. A feed of the aliphatic hydrocarbon is mixed with a recycle gas and the mixture is contacted with the catalyst. The resultant conversion product is separated into a gas phase and a liquid phase containing aromatic hydrocarbons. The gas phase is separated into a hydrogen-rich gas and a methane- and/or ethane-rich gas while the liquid phase is separated into an aromatic hydrocarbon-containing product and a light hydrocarbon-containing gas. At least part of the methane- and/or ethane-rich gas and the light hydrocarbon-containing gas is recycled as the above recycle gas. The catalytic conversion is performed while increasing the reaction temperature as the process proceeds.

Abstract: The invention relates to a thermoplastic elastomer composition comprising a) a polyolefin and b) a crosslinked ethylene copolymer, the crosslinks between the main chains of the molecules of which have been formed of the hetero groups of at least two comonomer units being in different main chains and at least two hetero groups of the crosslinking-agent molecule being chemically attached to each other. The problem of such a mixture is that the lipophilic thermoplastic polyolefin and the ethylene copolymer to be crosslinked with its polar hetero groups are not compatible. Now, the problem has been solved by forming the crosslinks between the main chains so that either the hetero group of the comonomer unit in the main chain or then the hetero group of the crosslinking agent molecule always is a hydroxyl group, the hydroxyl group always forming a permanent oxygen crosslink bond with the other hetero group attached to it.
