Filed: 1988-02-05
Abstract: Manufacture of low-emission polymer emulsion paints, coatings and plasters in the form of aqueous preparations based on aqueous dispersions of copolymers of olefinically unsaturated monomers wherein the pigment volume concentration (PVC) is not less than 60% and which contain water, fillers, pigments, emulsion copolymers and customary assistants, the emulsion copolymers containing from 0.05 to 2% by weight of monomer units from specific unsaturated hydrolysable organic silicon compounds and the aqueous copolymer dispersions having a minimum film-forming temperature (MFFT) of <10 DEG C, preferably <5 DEG C, in particular <2 DEG C. The aqueous preparations according to the invention contain <0.1% by weight of non-aqueous volatiles, based on the total non-volatile content of the preparations, and the pH of the aqueous preparations is within the range from 5.5 to 10. The low-emission aqueous preparations manufactured according to the invention are in particular free of volatile organic solvents, volatile organic film-forming aids, low molecular weight plasticisers, residual monomers from the emulsion copolymerisation, other, non- aqueous volatiles and malodorous by-products. Use of the emulsion-based paints, coatings and plasters as preservatives for structures and buildings or as building materials, in particular in inadequately ventilated and in inhabited rooms.

Title: Door-actuating arrangement for rail vehicles
Inventor: VOGELSANG HEINRICH
IPC: E05B79/20
Filed: 1988-02-23
Abstract: The invention relates to a door-actuating arrangement for rail vehicles with, accommodated in the bodywork, in each case one inner and outer fitting with a gripping flap, which unlocks the door lock via Bowden pulls. The aim of the invention is to produce, with few components, a pressuretight, operationally reliable actuating arrangement, the elements of which are disconnected in relation to one another and can be disabled from the control position. This aim is achieved by the gripping flap of the inner fitting being connected via a shaft to a first segment plate which has a tangential slot, by there being arranged on the shaft a second segment plate which bears a compressed-air cylinder, the piston rod of which engages in the slot of the first segment plate, and by a Bowden pull leading to the door lock and a Bowden pull leading to the outer fitting being mounted on the second segment plate. <IMAGE>

Filed: 1988-03-15
Abstract: Control device for a test stand for the testing of motor vehicle drive assemblies on their own or in vehicles, having a front machine (3) which can be coupled via at least one gearbox to at least two rear machines. The front machine (3) is an electric or an internal combustion engine which is arranged as control element in a control arrangement or as actuator in a first control loop (15) which can be installed selectively for torque or rotational speed control. The rear machines (11, 12, 13, 14) are electrical or hydraulic machines which are resepectively arranged as actuators in further control loops (21, 22, 23, 24) which can be set selectively for torque or rotational speed control. For the decoupling of torques, those torques which are introduced into the control loops set for torque control are fed in as disturbing variables in the control loops set for rotation or speed control. For decoupling rotational speed of the control loops set for torque control, acceleration moments are fed in as disturbing variables at the same time as the rotational speed changes. <IMAGE>

Title: Method for analog/digital conversion by successive approximation with a very high sampling rate
Inventor: TEUCHERT DIETER
IPC: H03M1/44
Filed: 1988-12-10
Abstract: Technical problem In analog/digital conversion in very fast transient recorders, clock times of about 10<-8> sec can be achieved by elaborate methods (flash ADC). The new method is simple and provides for shorter clock times. Solution of the problem The method of successive approximation can be used in the case of clock times of 10<-9> sec, as follows: conversion is carried out in a number of identical converter stages with controlled signal transit time which are connected in series with one another in a cascade and with low reaction. In each stage, the input signal is sampled and compensated in accordance with the weighting of the relevant stage. The converter stages process the input signal in pipe-line mode. An input signal with predetermined timing passes successively through the converter stages in the direction of decreasing weighting but input signals following one another in time are processed simultaneously in a number of converter stages. Field of application The method is suitable for constructing an analog/digital converter for transient recorders with a very high sampling rate in fast semiconductor technologies with a low level of integration (GaAs, ECL).

Title: Trouser leg ironing - with under-shoe station having ironing beams to take legs and then move into press station for single-stage ironing
Inventor: KIEPSCH HEINZ
IPC: D06F71/29
Filed: 1989-08-12
Abstract: To iron seamed tubular fabric sections, such as trouser legs, at least one workpiece is passed with its two seamed pair of legs to an extended multi-beam undershoe workstation. At least one leg is drawn over each pair of adjacent ironing beams at a determined working area of the station. A linear alignment of both upwards positiioned leg pair starts as they are moved in sections over the curved surface outwards to give a binary fixing as the start ends of the legs are locked and the remainder hangs free as a tube. The charged undershoe station is passed into an ironing press where, at the latest after its insertion, there is an automatic and continuous opening and spreading of the pair of legs at least in the longitudinal direction. When the undershoe station has moved horizontally to its final position, it is lifted and the material is pressed, between the undershoe and the profiled iron unit, evenly over its whole surface including the curved seams according to the leg characteristics, without steam. The undershoe is then lowered vertically and drawn out of the pressing station in a straight line, and brought to rest when it reaches the end of the working zone to be unloaded and the process repeated. ADVANTAGE - The trousers can be effectively ironed in a single and fast operation.

Patent DE-4009035-A1 (DE)
Inventor: BAUER HANS JUERGEN
IPC: F16F9/02
Filed: 1990-03-21
Abstract: A pneumatic spring of adjustable length has a valve (19) possessing a valve pin (46) which is arranged displaceably in a valve body (21). Arranged on both sides of a valve-body inner space (43) are O-ring gaskets (47, 50) which bear against cylindrical portions (48, 49) of differing diameter (d1, d2). Grooves (60, 60') are formed, at least for bridging an O-ring gasket (50, 47), in an associated cylindrical portion (49, 48). When the corresponding O-ring gasket (50, 47) is bridged as a result of the displacement of the valve pin (46), the respective O-ring gasket (50 or 47) remains bearing against the cylindrical outer face (62, 66) of the corresponding cylindrical portion (49, 48), so that there is no possibility that the gaskets will experience wear and therefore that the pneumatic spring will become useless.
