Abstract: A process for the epoxidation of propene involves reacting propene with hydrogen peroxide, in the presence of a methanol solvent and a shaped titanium zeolite epoxidation catalyst in a fixed bed reactor. The process then involves recovering methanol from the reaction mixture, treatment of the recovered methanol by passing it through a bed of an acidic ion exchange resin, and recycling the treated methanol to the epoxidation reaction; as well as regeneration of the acidic ion exchange resin. Catalyst breakage can be reduced or avoided by washing the regenerated bed of an acidic ion exchange resin with methanol until the methanol exiting the resin bed has an apparent pH higher than 1.8, before methanol treated with the acidic ion exchange resin is recycled to the epoxidation reaction.

Abstract: The invention relates to an applicator device for applying wrapping labels (13) to packagings (15), having a transverse transport device (19) which is configured for transporting a label, which is first of all dispensed by a label dispenser, in particular a label printer (11), in the vertical direction into an intermediate position, from the intermediate position transversely with respect to the vertical into an application position, in which the label can be received by a packaging which is running through.

Abstract: The invention relates to a labelling apparatus comprising a blow device which allows compressed-air controlled delivery of a label to an object to be labelled, wherein the blow device comprises a compressed-air providing device, a plurality of nozzles for applying compressed air to the label, a distribution space which is operatively connected for fluid communication with the compressed-air providing device and the nozzles, and at least one deflector which is arranged in the distribution space, wherein the distribution space has arranged therein a porous device which surrounds the at least one deflector.

Abstract: The invention relates to a method for the provision of activated temperature-sensitive and/or time-sensitive indicators for product marking. A first variant is characterized by the activation of an indicator and the subsequent application of a protective filter to the indicator, with the indicator being conveyed along an activation device and along a protective filter application unit subsequent to it in the conveying direction. A second variant is characterized by the activation of an indicator already provided with a protective filter. The invention furthermore relates to apparatus for the carrying out of the named methods as well as to a product marking which was manufactured in accordance with the methods in accordance with the invention.

Abstract: The printing device comprises a print head unit, a transporting device for the printing material and a structural housing board on which the print head unit and the transporting device are mounted at one end in cantilevered manner and in a predetermined relationship relative to one another. The transporting device comprises a stiff support member which is rigidly connected to the housing board, a mounting member which extends substantially parallel relative to the housing board and is held on the stiff support member, and at least one transport roller for the transportation of the strip of printing material which is mounted at both ends. The stiff support member comprises connecting elements for releasably fixing th mounting member and also guide elements which co-operate with corresponding guide elements of the mounting member for exactly positioning the arrangement with reference to the support member.

Abstract: In order to make it possible to change over quickly and easily to different label sizes and shapes in a labeling apparatus for the application of labels to packages and goods comprising a label dispensing device and an air-blast labeling device, wherein the label dispensing device supplies labels individually from a supply to the air-blast labeling device and wherein the air-blast labeling device has an underpressure chamber with a suction plate having a plurality of openings for drawing in the labels supplied by the label dispensing device, a source of compressed air with a compressed-air distributor which has an air-blast plate arranged adjacent the suction plate and provided with a plurality of openings, as well as a compressed-air pulse generator which directs a blast of compressed air from the source of compressed air through the air-blast plate of the compressed-air distributor and through the suction plate against the label held by the suction plate in order to release this from the suction plate and c
