Title: Prepn. of salt of poly:carboxylic acid partial ester - by condensing acid with fatty alcohol alkoxylate prepn. in presence of calcined hydrotalcite as alkoxylation catalyst
Inventor: BUNTE REINHARD DR
IPC: C09K23/36
Filed: 1990-08-16
Abstract: Salts of polycarboxylic acid partial esters are prepd. by partial condensn. of (A) (a) aliphatic, (un)branched dicarboxylic acids, (b) cycloaliphatic polycarboxylic acids, (c) aromatic polycarboxylic acids or (d) hydroxypolycarboxylic acids, with (B) fatty alcohol olefin oxide adducts prepd. in presence of calcined hydrotalcites as alkoxylation catalyst, followed by neutralisation with aq. bases. Acids are: (a) 2-12C, with O or 1 C=C bond, (b) 7-12C with 2-6C COOH, (c) 8-12C with 2-6 COOH.  USE/ADVANTAGE - Salts are used as surfactants or in prepn. of surfactants. Salts lower the surface tension of water and promote the wetting of solid surfaces with water, and can be used in emulsifying oils and fats in aq. systems. Salts have a much lower viscosity than similar cpds. prepd. with fatty alcohol alkoxylates obtd. with the usual catalysts, e.g. Na methylate. Foaming power is also greater, of advantage in cosmetics.

Patent DE-4039643-A1 (DE)
Inventor: BERG JOACHIM
IPC: F23N1/08
Filed: 1990-12-12
Abstract: The present invention relates to a method for controlling the heating water circulation in a gas-fired water heater, consisting of at least one heat exchanger (2, 3) which is heated by a burner (1) and to which a heating water forward run pipe (8) with a temperature sensor (9) for forward run temperature regulation and a heating water return run pipe (7), in which there is a heating water circulating pump (6), are connected, the forward run temperature T2 being constantly controlled, and compared with a maximum forward run temperature Tmax stored in a regulating device (15) which is line-connected to an automatic firing machine (14) and the burner (1) being switched off in the event that this temperature is exceeded. In order to guarantee reliable switching off in the event of low water, it is envisaged according to the invention that the heating water temperature is measured at an additional point approximately in the centre between forward and return run pipe (7, 8) and the temperature difference  DELTA  T between the forward run temperature T2 and this heating water temperature T1 is determined. This temperature difference  DELTA  T is compared with a maximum temperature difference  DELTA Tmax and a minimum temperature difference  DELTA  Tmin stored in the regulating device (15) and this temperature difference  DELTA  T is used as second switch-off criterion  DELTA  T <  DELTA  Tmin, in addition to the first switch-off criterion T2 - T1 >  DELTA  Tmax. <IMAGE>

Filed: 1991-03-11
Abstract: In a control device (S) for a hydraulic motor (V) which is adapted to be acted upon at both sides, there are provided  working conduits (4, 5) which are alternately connectable via a directional control valve (C) to a pressure source (P) and a tank (T), a load holding valve (H) which is hydraulically openable in a controlled way and is arranged in at least one working conduit (4), as well as a control pressure conduit (13) which is connected to the opening side (16) of said load holding valve (H), with pressure variations arising during the controlled opening of the load holding valve, and the amplitudes of the pressure variations being adapted to be dampened in the control pressure conduit (13) at least via a damping throttle (D). To dampen and eliminate the undesired effect of changes in the viscosity of the pressure medium and/or of a damping throttle which is too tightly set, the damping throttle (D) can be bypassed in both directions by a respective check valve (R1, R2, R1', R2,), a great biasing force which biases the one check valve being adjusted to a value which lies between the pressure values of the pressure extremes that act on said check valve and pertain to at least the first amplitude and the next amplitude of the pressure variations.

Title: Polarising sun protection plate using polarisation sheet for vehicle or building - employs liq. crystal technique with strip-form polarising area or full surface, arrangement with mechanically activated analysis unit
Inventor: AGOT ERIC JOEL DIPL ING
IPC: B60J3/06
Filed: 1991-03-23
Abstract: With the liquid crystal sun protection concept, double-walled glass plates (9) are used, between which an adhesive foil (10) and a liuquid crystal module (Y) are integrated. A plate frame (1) and a liq. crystal frame (2) are involved, with a linearly polarisign analysis unit (8), organic substance (4, light-permeable, electrically conductive coating (5, 6) togehter with two glass coating carriers (7), current leads (11), an AC source (12), and a switch (13). In the rest state, the switch (13) is open, the polarising filters (3, 8) are arranged parallel, and the organic substance (4) is not electrically activated. With pole filters with 42 per cent light permeability approximately 17.64 per cent of the light passes through the liq. crystal layer. When no light is required, the switch (13) is closed, the organic substance (4) is electrically activated and the light allowed through by the polarising unit is polarised. The light is turned through 90 deg. and can then no longer pass through the analyst unit. In this way, a 100 per cent sun protection is achieved. USE - Controllable sun protection for use in buildings, vehicles boats etc.
