Title: Emulsifier, suitable for preparing an aqueous emulsion
Inventor: MARUHASHI MOTOKAZU
IPC: C09K23/52
Filed: 1981-06-24
Abstract: An emulsifier is described, suitable for preparing an aqueous emulsion having a high viscosity, containing a copolymer of 1) at least one monomer, selected from a vinyl ester, vinyl alcohol, an alkyl acrylate and an alkyl methacrylate and 2) at least one monomer, selected from an acrylic acid derivative having the general formula  CH2=CR<1>-CO-A-R<3>-SO3M  and a maleic acid derivative having the general formula <IMAGE> in which R<1> is hydrogen or the methyl group, R<2> is an alkylene group, R<3> is hydrogen, an alkyl group or an alkali metal, M is hydrogen or an alkali metal and A is -O- or -NR-, where R is hydrogen, an alkyl group or -R<2>SO3M. Emulsions prepared with the use of the abovementioned copolymer as an emulsifier have very high viscosities and a very long shelf life, freeze-thaw stability and dilution stability. The use of the abovementioned copolymer in combination with a surfactant results in emulsions which contain virtually no aggregates and coarse particles and have an improved flowability.

Title: Hydraulic booster valve for brake systems
Inventor: KIRCHER DIETER DIPL ING
IPC: B60T13/12
Filed: 1982-04-08
Abstract: The hydraulic booster valve (1) has a control slide valve bore (3) in the valve housing (2), in which a control slide valve (4) is arranged so as to be axially displaceable, a pressure control passage (6) and a return control passage (7) being formed in the valve housing (2), which passages open out into the control slide valve bore (3), it being possible to close the return control passage (7) by means of actuation of the control slide valve (4) prior to or simultaneously with the opening of the pressure control passage (6) and a first overlap area (11) being provided between the pressure control passage (6) and a radial control groove (8) of the control slide valve (4). In order to achieve low sliding forces on the control slide valve (4) with a simplified construction and thereby to be able to use the booster valve also in the high pressure range, it is proposed that the radial control groove (8) be broader than the first overlap area (11), that a second overlap area (12) be provided in the actuating direction prior to the first overlap area (11), the second overlap area being narrower than the first overlap area (11) and narrower than the radial control groove (8), and that between the overlap areas (11, 12) in the valve housing a recess (9) opening out into the control slide valve bore (3) be provided which is wider than the second overlap area (12). <IMAGE>

Title: Large-area footpath flagstone
Inventor: CASPARI ROLF
IPC: E01C15/00
Filed: 1982-07-23
Abstract: The large-area footpath flagstone is preferably suitable for laying on footpaths running parallel to the street. While the aim is to be seen in preparing a footpath flagstone which permits a significant increase in productivity in the making of footpaths while reducing labour, the object is to provide a large-area footpath flagstone on which the structural termination with respect to the carriageway is optically visible, on which the function of the footpath is preserved in the event of brief overloading and which is furthermore suitable for absorbing impact forces from vehicles and draining away surface water which occurs. This is achieved substantially by the footpath flagstone (1) covering the entire width of the footpath, the face pointing towards the carriageway being designed as a slope (4) in the form of a kerb, the surface of the footpath flagstone (1) having a lattice-shaped grid (2) and the footpath flagstone being provided with transport reinforcement known per se. <IMAGE>

Title: Process and apparatus for drying previously dewatered sewage sludges
Inventor: KREYENBERG HEINER DIPL ING
IPC: C02F11/13
Filed: 1982-09-16
Abstract: With the aim of removing residual water from previously mechanically dewatered sewage sludges in a simple and economic manner to give about 100% dry matter (DM) with disruption of the capillary forces of the cells of the solids, in a first process step, the previously dewatered sewage sludge is stirred, tumbled and/or kneaded with continuous mass circulation. At the same time, the product temperature is increased to about the boiling point of the mixture. In a second process step, the vapours obtained on the one hand are condensed and in a third step the dry matter obtained on the other is burnt to obtain the process heat to increase the product temperature (first process step).
Patent DE-3235544-A1 (DE)
Title: Drill hammer
Inventor: BUCK MANFRED DIPL ING
IPC: F16D7/04
Filed: 1982-09-25
Abstract: An electric hand tool, preferably a drill hammer with an air-cushioned percussion mechanism (6), is proposed, in which the rotary drive, controllable via switching means (50, 60, 100, 110, 120) actuable from outside, is imparted to the tool via a safety coupling (33, 34', 37, 39; 62, 69, 70; 63, 68; 72, 79, 80; 73, 77, 78). In order that this safety coupling provides the desired safety, it must not be set too high in terms of torque. This has the disadvantage, however, that the safety coupling comes into action almost constantly when drilling with tools requiring a large torque. For this reason, according to the invention the moment of release of the safety coupling can be adjusted, preferably increased, from outside via actuating means (50, 60, 100, 110, 120). <IMAGE>

Title: Process for printing textile materials made of cellulose fibres or blends thereof with synthetic fibres with disperse dyes
Inventor: KUTSCHERA PETER
IPC: D06P1/58
Filed: 1982-10-19
Abstract: Process for printing textile materials made of cellulose fibres or blends thereof with synthetic fibres with disperse dyes by the discharge resist method whereby the ground of the material is dyed with a print paste which contains a synthetic carboxyl-containing thickener which has been at least partially neutralised with ammonia to a pH within the range from 3 to 8, an N-methylol compound or an N-methylol ether compound of urea or urea derivatives and at least one disperse dye which is alkali-dischargeable to white. The fixation of the alkali-dischargeable disperse dyes for the ground dyeing and of the alkali-stable disperse dyes for the resist print paste is effected by heating the textile material to above 140 DEG C in the absence of inorganic catalysts for curing N-methylol or N-methylol ether compounds of urea or urea derivatives.
