Title: Testing pressure variations in press - by hot pressing resin=impregnated sheet together with absorbent sheet whose colour variations produced indicate high and low pressure areas
Inventor: MENHOFER PETER
IPC: G01L5/00
Filed: 1991-02-19
Abstract: The pressure applied over areas by presses for hot pressing laminates are tested by placing a test laminate of resin-impregnated sheets between the platens and hot pressing this together with an absorbent sheet on at least one of its sides. The figure shows one press daylight with two heated platens (1,2) and polished thin metal cauls (3,4) next to the laminar stacks (5,6) on the othersides also (7,8). A test laminate (9) is placed at the centre and consists of a rigid thermally stable substrate film (10), a dark-coloured resin-impregnated sheet (11) and a light-coloured absorbent sheet (12) plus a strip-off separator film (13). The sheets (11) and (12) can be paper. Under the pressure and heat resin is pressed proportionally to the pressure control out of the impregnated sheet (11) into the absorbent layer (12). An absorbent layer (12) can also be used each side rather than merely one. The colours of the sheet (12) when the separator (13) has been removed indicate the areas of high and low pressure produced. ADVANTAGE - The method tests the press under production conditions (i.e. not e.g. cold as hitherto).

Inventor: FINKELMANN HEINO PROF DR
IPC: C09K19/40
Filed: 1991-07-26
Abstract: The invention concerns a method for the production of liquid-crystal elastomers or duromers with a permanently fixed anisotropic reticular structure, the method being characterized in that liquid-crystalline elastomers containing reactive units with unreacted functional groups are oriented in a first step by the application of a mechanical stress, this orientation subsequently being fixed in a second step by linking at least some of the reactive units to polymer chains. The invention also concerns the liquid-crystal elastomers and duromers with a permanently fixed anisotropic reticular structure produced by this mehtod.

Filed: 1992-06-29
Abstract: Equipment for dismantling cassettes automatically has devices to feed in the cassettes, others to separate the cassette casings and interiors; and others again to collect the separated parts. A conveyor belt (10) feeds the cassettes (14) to the machine which has two counter-rotating spiked rollers (1) whose point (11, 12) do not acutally meet as they turn. The points (11, 12) pass through the casing s(15, 16) and tear them, so that the tape (17) inside and the internal parts (18) drop out. Plates (8) move the casings (15, 16) away fromthe rollers so that they (15, 16) drop on to chutes (9) and fall into containers (4). The tapes (17) and internal parts (18) fall onto a vibrating screen (3) aand the latter (18) pass through into the container (7) below. The tapes (17) are moved to rollers (2), where they are separated from parts (15, 16) of the casing (if present) and are drawn off (6) to a container (5). ADVANTAGE - The equipment dispenses with the time-consuming and therfore expansive manual process of opening the cassettes (which has been the method hitherto).

Inventor: UHRIG RUDOLF
IPC: B41F7/26
Filed: 1993-02-05
Abstract: The feedback control of the damping-solution supply in an offset printing press uses a damping roller with controllable wetting properties. Given a constant supply of damping solution to the damping unit, the solution is able to be transferred onto the printed product in a manner suited to the printed subject. This is achieved by providing at least one polymer-coated damping roller (3) in the damping unit (1) of the offset printing press, with the wetting behaviour of the damping roller (3) being continuously settable, depending on the state of charge, between an hydrophilic state and an hydrophobic state, and by providing a control apparatus (7) which sets the wetting behaviour of individual surface regions (8) of the damping roller (3) as a function of the required quantity of damping solution. The polymer coated surface of the roller is preferably divided into regions which are electrically insulated from each other. <IMAGE>

Title: Process and apparatus for the conveyance of a material web
Inventor: FIWEK WOLFGANG
IPC: B65H23/188
Filed: 1993-04-05
Abstract: What are described are a process and an apparatus for the conveyance of a material web, especially of a strip of labels hanging together, in which the material web (13) is unwound from a stock roll (12), moved along a conveying stage and advanced at a predetermined speed of advance into the entry zone of a removal device. The conveying stage for the material web (13) runs through a loop store having fixed deflecting rollers (58, 59, 61) and jockey rollers (64, 66) movable relative to these. By means of a motor (83) controlled by a control arrangement (44), the jockey rollers are moved relative to the fixed deflecting rollers by a toothed belt (77) having double toothing, in order to compensate web-length differences which occur particularly when the material web (13) is being started and stopped.   The advantage of this procedure is that the advance of the material web (13) into the removal device is free of restraining forces of the stock roller (12) particularly during the critical phases of the stopping and starting of the material web. <IMAGE>
