Patent DE-3839773-A1 (DE)
Title: Continuous casting installation with a downstream rolling mill
Inventor: MALINOWSKI HANS
IPC: C21D9/00
Filed: 1988-11-25
Abstract: Hitherto, the strip-shaped feedstock emerging from a continuous casting installation has been wound helically into a coil in a special apparatus, then temporarily stored in a holding furnace and then unwound again in another apparatus before being fed to the rolling mill for rolling down. Here, it is not only disadvantageous that the large number of stations arranged in series take up a relatively large amount of room and space; a high outlay on machines and energy is also required for transporting and maintaining the temperature of the cast strand. According to the invention, this is avoided by virtue of the fact that the holding furnace consists of an elongate chamber (3) which runs transversely to the continuous-casting installation, into which chamber the feedstock (10) is introduced at the side at one end (31) and from which the said feedstock is removed at a laterally offset position at the other end (32), deflection and supporting rollers (33) running in the longitudinal direction of the chamber being arranged in the chamber (3) in the inlet region for the feedstock (10), these rollers forming a helical coil (11) from the feedstock in the chamber (3). <IMAGE>

Title: Liquid container
Inventor: LUDWIG KLAUS-DIETER DIPL ING
IPC: B65D90/503
Filed: 1988-12-09
Abstract: The invention sets out from a liquid container, such as a storage tank, made of metal, in particular of steel, preferably for above ground and underground installation, having an inner casing, an outer casing, an intermediate space being formed at the end in the inner and outer casing, having a suction connection and a measuring connection for the connection of a measuring instrument, both connections being connected to the intermediate space in the tank. To accelerate a warning of a leakage, even in the case of viscous liquids, it is proposed to provide a flow path (17) with cross-sectional dimensions, namely height and width, which both lie essentially above the width of the intermediate space (8) defined by the distance between the inner and outer casing (6, 7), the intention being for the flow path to be in liquid connection with the intermediate space (8). <IMAGE>

Patent DE-3900734-A1 (DE)
Title: Apparatus for straightening and cutting off round wire or the like
Inventor: DEITERS EBERHARD DIPL ING
IPC: B21F1/02
Filed: 1989-01-12
Abstract: To straighten and cut off round wire or comparable material, wire-straightening and cutting-off machines are known, in which the particular material is transported through a straightening rotor by means of draw-in rollers and is subsequently separated into equal-length sections by means of a cutting apparatus. Since the cutting operation requires a brief stoppage of the material to be straightened, surface damage on the material and thus a loss in quality result owing to the continuous drive of the draw-in rollers and the straightening rotor. In an apparatus according to the invention, a straightening rotor (20) and a pair of draw-in rollers (24) are accommodated as feed means jointly on a slide (3) capable of being driven in oscillating fashion parallel to the feed direction, the cutting apparatus (8) being fixedly arranged. The slide (3) is driven, according to the invention, in such a controlled manner that, at the time of the cutting, it is moved opposite to the feed direction of the material (12), during which it is matched to the feed speed of the material (12) such that both speeds virtually compensate each other or, when a numerical control system is employed, cancel each other out completely. Thus, despite the continuous drive of the straightening rotor (20) and of the draw-in rollers (24), a stoppage of the material (12) in the cutting apparatus (8) is made possible in a manner free from damage and hence also straightening and cutting off with little damage. <IMAGE>
Patent DE-3908110-A1 (DE)
Title: Safety door lock with a safety catch
Inventor: DILLER GUENTER
IPC: E05B55/12
Filed: 1989-03-13
Abstract: When entrance doors to houses are only drawn shut, the known door locks with catch can easily be opened using a wire, a cheque card etc. The novel design is intended to lock the catch without the bolt.   When the house door is drawn shut, the incorporated switch slide (3) runs in synchrony with the catch (1) back into the lock and frees the switch pin (5) of the catch bolt (6), so that the latter drops onto the running surface (7). When the catch has reached its end position in the angled opening of the strike plate, the catch bolt drops and effects blocking. The switch slide (3) engages under spring pressure (12) on the switch lug (8). The lock is opened using a key or by means of the door handle, as a result of which the locking of the catch by means of a switch pin (10) is cancelled via the connecting rod (11) and catch lever (9), so that the catch can be drawn in. When the catch returns to its rest position, the cam (13) runs under the switch pin (5) and stops the catch bolt. On account of its automatic catch locking, the safety door lock is particularly suitable for house doors. <IMAGE>

Title: Toxic waste esp. halogenated organic and heavy metal disposal - by fixing with synthetic calcium hydro-silicate and opt. calcium aluminosilicate
IPC: C04B7/24
Filed: 1989-12-11
Abstract: Disposal of toxic waste, esp. contg. halogenated organic cpds. and/or heavy metals, involves mixing sources of Ca2+ ions and silicate ions with water and the waste to form a mineral carrier of completely synthetic Ca hydro-silicate (I), which binds the waste. A source of Al3+ ions may also be added, to give a mixt. of (I) and completely synthetic Ca aluminohydro-silicate (II) as carrier. Pref. (I) is tobermorite (IA) and (II) is gismondite (IIA). Ca(OH)2 may also be formed. The ions are used in such amts. that the molar ratios are 0-20, pref. 0-5 mole (IIA) and 0-100 pref. 2-50 mole Ca(OH)2/mole (IA). For waste contg. heavy metals, the ratio is 1-5 mole (IIA)/mole (IA); and for organic waste 10-50 mole Ca(OH)2/mole (IA). The amt. of Ca2+ ion source is 0.05-10, pref. 0.1-1.5 pts./pt. waste. Water is added in an amt. giving a dry prod. The ion sources are quicklime or water-sol. Ca salts, water-sol. Al salts and water-sol. silicates. USE/ADVANTAGE - The carrier has the ion exchange properties of an aluminosilicate of the zeolite type and also forms a thermodynamically stable fixative for the toxic waste. It is useful for the disposal of polychlorobiphenyls (PCB), halogenated solvents, polychlorinated phenols (PCP), waste oil unsuitable for recycling, oil emuslions, chlorinated lubricating greases, acidic resins, e.g, from the treatment of paraffins with H2SO4, paint and lacquer residues, plastics waste in liq., paste or crushed form, e.g, polyurethanes, phenolic resins etc., or sludge contg. heavy metals.

Title: Anti-skid tyre tread for wet conditions - has series of ribs and grooves running from bends V=shaped to meet centre line at acute angle and ribs with obtuse cross-cuts
Inventor: KUHR WOLFGANG DIPL ING
IPC: B60C11/03
Filed: 1989-12-20
Abstract: A radial tyre has a tread with a number of obliquely disposed rib features running at an acute angle to the circumferential centre line, and grooves parallel to them and ending in bends at the shoulders. These features on the one half of the tread run opposite to those on the other half, the grooves running outwards from the centre line at an acute angle to it. The ribs concerned are joined together at the centre line so that the starts of the grooves are offset from each other circumferentially. The bends in the grooves are at the ends between the centre and shoulder. The shoulder grooves run at 95-125 deg. (as measured along their centres) and are open ended at the shoulders. The ribs have at least partial cross-cuts 0.45-2.5mm wide running parallel to those at the shoulder and disposed in V-shapes across the tread width. ADVANTAGE - The treads provide an improved non-skin behaviour in wet conditions (i.e., better than the parent patent) when used for wide tyres with height/width ratios up to 0.6. This improvement is achieved without adverse effect on resistance to skidding in dry conditions, or lateral loads or resistance to tracks.

Title: Use of glutamic acid or derivs. for treating hypertension - by oral admin., effective for patients not responding to other treatments
Inventor: ARNIM ULRICH-CHRISTOPH VON
IPC: A61K31/195
Filed: 1990-02-14
Abstract: The use of glutamic acid (I) or related amino acids, or their derivs., metabolites or salts, for the oral treatment of hypertension is claimed. The dose is up to 30 g or more per day, esp. 3 4g doses initially and the 3 2g doses for maintenance. If required, (I) is administered together with a saliuretic, other antihypertensives or Mg, and provides blood pressure readings of 140 +/- 25 mm systolic and 70 +/- 20 mm diastolic. USE/ADVANTAGE - Since intravenous admin. of (I) is known to increase the blood level of adrenaline and other vasoconstrictors its use in hypertensive patients has been contraindicated. It is now found, however, that oral admin. of (I) reduces blood pressure, even in patients who do not respond to conventional treatments. (I) can cause mild sleep disturbance but this wears off after a week and in no cases has it been severe  enough to cause the treatment to be discontinued.
