Title: Process for preparing waterswellable polymers using sodium thiosulfate as part of a redox initiator system
IPC: C08F2/10
Filed: 1989-01-07
Granted: 1993-08-04
Abstract: This invention relates to a process for preparing a water-swellable polymer which comprises polymerizing an aqueous solution of an  alpha , beta -ethylenically unsaturated monomer and at least one crosslinking monomer in the presence of an effective amount of sodium thiosulfate as a component of a redox initiator system. The use of sodium thiosulfate as a component of a redox initiator system for the polymerization allows for controlling the rate of initiation so as to increase the time required for gel formation during polymerization. The resulting hydrated polymer of the present invention breaks up more uniformly and with greater ease resulting in a higher per batch yield.

Abstract: The system operating in accordance with the principle of chain synchronization, comprising a central station (Z) having several two-core primary signalling lines (ML), to which a plurality of detectors (Mn) are connected in the form of a chain which are regularly cyclically activated from the central station (Z) and are interrogated for their respective analog detector measurement value, in each case uses detectors (Mn) which exhibit a voltage measuring device (MU) which monitors the applied line voltage (UL), a subsequent logic circuit (VL) with associated sensor part (S), a subsequent control device (St), an energy accumulator (C) and a switching transistor (T). The logic circuit (VL) is essentially formed by a microprocessor which can be connected and disconnected. According to the invention, the microprocessor is switched into a current-saving standby condition and switched on again in dependence on particular switching criteria which are specific for the hazard signalling system, a required start-up time (tan) being ensured for the microprocessor. For example, the microprocessor is switched to the standby condition in dependence on a particular line voltage (disconnecting voltage UAB=UR) and switched on again with the presence of another predetermined line voltage (connecting voltage UAN=US) so that the detector is activated after a particular start-up time (tan=ts). <IMAGE>

Date Jun. 15, 1989.A method for conveying and depositing an adhesive, flexible material by way of a flexible base in right side up position which essentially maintains it shape in a deposition station. The base is supported by a displaceable supporting device equipped with a guiding member, which imparts a direction change to the base. The supporting device at the deposition moves the base away below the material causing the material to be deposited by means of free fall. The material is positioned on the base a distance from the delivery end of the supporting device corresponding to the acceleration distance of the base. The rear end of the base is fixedly attached against displacement. The base is urged to make an abrupt direction change over a guiding member having a very small curvature radius (r) at the front end of the supporting device. The supporting device and the base are simultaneously accelerated rearwardly at an acceleration, which should be at least 1 g.

Abstract: The elevation platform (1) has a workpiece support (5) guided movably up and down in a housing (2), this support making it possible for a disc-like workpiece (6) to be transported into a process chamber (36) of a vacuum installation. In order to correct the position of the workpiece (6) deposited by a machine onto the workpiece support (5) and to secure the workpiece during transport, use is made of holding members (30) arranged on opposite sides on the elevating platform (1). These each consist of a bar (20) on the end of an extension arm (14) which is arranged on a shaft (10) mounted rotatably in the elevating platform, this shaft being rotatable within a swivel region by means of a motor (12), in order to bring the holding member (30) into one of two different positions. The position of the workpiece (6) on the workpiece support (5) can be corrected by means of two holding members (30) arranged next to one another on the one side of the elevating platform and a holding element arranged on the opposite side of the elevating platform. A disc (29) arranged at the end of each bar (20) of the holding member (30) engages over the edge of the workpiece and secures this during upward conveyance. The holding member (30) is then swivelled outwards by means of a motor and comes to lie with the disc (29) under a cover (34), so as to be protected from the effects of the surface treatment of the workpiece (6) in the processing chamber (36). The workpiece support (5) includes a heating means (50) having a heating spiral (56) arranged inside a groove (52) in a plate (51). Flowing through the groove (52) is a gas which emerges through small bores provided in the plate (55) covering the groove, so as to form a gas cushion which serves as a heat-conducting means and for a uniform heating or cooling of the workpiece.
