Title: Removal of mercury@ from liquids, e.g. alkali alkoxide solns. - by contacting liq. with fibres which are coated with a silver@ layer
Inventor: ZOCHE GUENTER DR
IPC: C07C29/76
Filed: 1992-06-27
Abstract: Removal of mercury from liquids, by formation of an amalgam with silver, comprises contacting the liquid contg. the mercury with fibres which are coated with a layer of silver. USE/ADVANTAGE - The process is useful e.g., for removal of mercury from liquids resulting from prodn. of alkali lyes by amalgam processes, or prodn. of alkali; alkoxides by reaction of alcohols with alkali metal amalgam solns.. Removal of the mercury is esp. important when the liquids are to be used in food or pharmaceutical prodn.. The process gives better removal of mercury than other processes. In an example, a glass tube (inner dia. 2.7cm) was filled with 5g of polypropylene wool (fibre dia. 21m), which had been coated with silver (by immersion in silver salt soln. for 5 hrs.). The tube was heated to 60-80 deg. C and 300 g/hr. of MaOMe soln. (contg. ca. 600 ppt. of Hg) was passed through. The treated soln. contained only up to 5 ppt. of Hg, even when up to 181 kg of NaOMe soln. was treated.

Title: Asbestos-free felt for prodn. of high temp.-resistant gaskets etc. - contains mineral fibres, fillers and conventional binders, but no fibrillated (pulp) fibres
Inventor: SCHMIDT ULRICH DR
IPC: C09K3/10
Filed: 1992-09-09
Abstract: Asbestos-free non-woven fabric (I) based on mineral fibres (II), fillers and conventional binders is claimed. (I) contains no pulp fibre (III) and contains only mineral fibre (II) as support. Also claimed is a process for the prodn. of (I) on a wire web machine, by reversing the charge on (II) with a polymer (IV) in the pulp slurry, adding the latex to the slurry only just before putting it on the screen, precipitating with a salt and depositing the fabric on the screen with a unit wt. of more than 300 g/m2. USE/ADVANTAGE - Used for the prodn. of high temp.-resistant seals, esp. cylinder head gaskets, exhaust gaskets and other gaskets which are exposed to high temps. (claimed). The invention provides an asbestos-free gasket material which is prepd. without using fibrillated fibres (pulp fibres - III). These are organic fibres which are commonly used as process aids to maintain the same compsn. at the upper and lower sides of the fabric and reduce the amt. of material falling through the screen; however, even aramid fibres begin to decompose at 250-300 deg. C, which results in vol. shrinkage and failure of the gasket. Omission of pulp fibres also gives a redn. in cost.

ADVANTAGE- Has electrical contact for warning of brake wear, and uses detachable sensor which is inexpensive to mfr.
Patent DE-4238537-A1 (DE)
Inventor: RAMIN WOLFGANG
IPC: B23P19/06
Filed: 1992-11-14
Abstract: In a screwing device, the screwing blade (1) is connected to a drive member (7) via a screwing coupling (15). When the drive member (7) is actuated, the screwing blade (1) first performs a rotational movement and then an automatic advancing movement which adapts to the screw (11) to be screwed in. The drive motor (4) thus no longer needs to be moved towards the place-on foot (9) in order to screw in the screw (11), which makes handling easier and more convenient. Additionally, there results a shorter overall length and reduced weight of the screwing device. <IMAGE>

Patent DE-4315321-A1 (DE)
Title: Apparatus and process for drying sludges and polluted liquids by solar radiation
Inventor: LUBOSCHIK ULRICH
IPC: C02F11/131
Filed: 1993-05-08
Abstract: In the drying of sludges and highly polluted waste waters (effluents), in addition to suitable apparatuses, large amounts of energy generally of fossil origin are required to evaporate the water. The apparatus permits a simple construction with low expenditure in terms of material and exploitation of solar radiation as a regenerative energy source. The material to be dried is exposed to the solar radiation in a transparent structural enclosure such as in a greenhouse. To increase the drying rate, the incoming air and the material to be dried can additionally be heated, for which purpose low-temperature heat sources can also advantageously be used. In the case of a liquid, this is first passed into an aeratable sedimentation tank and thickened. A rotating and transport apparatus ensures contact with the air which takes up moisture. The energy of evaporation is essentially supplied directly to the wet material from the solar radiation. By exploiting a level difference, for instance by introducing a tower-like elevation or by utilising the shape of the terrain, a gravity-caused air current is induced which ensures removal of the moisture via the exhaust air.
Patent DE-4325467-A1 (DE)
Title: Method and devices for determining discrete values of filling levels and levels with remote interrogation for media of limited high viscosity and for liquids, using a tracking control system
Inventor: RAMMNER RUDOLF
IPC: G01F23/00
Filed: 1993-07-29
Abstract: The time-recording of levels or filling levels in the case of liquids often leaves much to be desired in terms of the precision desired, depending on the object to be measured and the measuring device used, particularly in the case of large ranges and a required great absolute accuracy. Analogue methods, for example using piezoresistive pressure sensors, fail. Here, the acquistion of discrete postions using many individual sensors offers a way out. However, the remote interrogation of long "digital graduated level recorders" becomes ever more expensive and energy-consuming with increasing longitudinal expansion, which can result in difficulties in the case of series of measurements of remote stations over a number of years. The total length of digital level recorders can apparently be shortened by using smaller level recorder pieces which track the liquid level in stages. Hence, only a greatly reduced quantity of sensors needs to be interrogated. The tracking is carried out with the aid of a small motor and a drive cord and it is controlled by means of upper and lower limiting value sensors (claim 3). With the reduction in the number of individual sensors needed, the electronic interrogation concept also becomes simpler. A reduction to one or two sensors (Claims 1 and 2) is conceivable, but requires more frequent motor activity.

Title: Reciprocating piston engine
IPC: F02B57/08
Filed: 1993-08-04
Abstract: In order to create a reciprocating piston engine with improved efficiency and increased power, it is proposed to form the cylinders (1) into a first rotary element (2), which rotates in a ring-shaped cylinder head (7). A second rotary element (6), which by way of positive synchronisation devices (11) rotates either counter to or in the same direction as the first rotary element (2), is rotationally fixed to the crankshaft (5), which is driven by the pistons (3) running in the cylinders (1) by way of connecting rods (4). Due to the rotation of the rotary elements (2, 6) the power output of the reciprocating piston engine can be doubled, compared to known reciprocating piston engines with the same displacement. At the same time, moveable valves in the cylinder head are no longer necessary (Fig.2). <IMAGE>

Title: Limiter for inrush current to capacitive load
Inventor: GOLDYN DIRK DIPL ING
IPC: H01H9/56
Filed: 1994-04-13
Abstract: A device to limit the inrush (surge) current when a capacitive load is switched onto the AC mains has a semiconducting switch (sg1) such as a triac, MOSFET or IGBT in series with the load (la) and a mechanical switch (sg2) e.g. a relay, in parallel with the triac. A control circuit (a) detects the voltage zero- crossing points of the mains waveform and at these points, makes the triac conducting immediately. After a short time period, it closes the mechanical switch so as to bridge the triac and take over the load current. The control circuit has a synchronising unit to detect the zero-crossing points, sending a signal to a logic unit activating the switches, plus an independent power supply.
