Title: Self-closing closure
Inventor: SUFFA UDO
IPC: B65D47/20
Filed: 1993-09-03
Abstract: The invention relates to a self-closing closure (1) for a container or a tube (2), preferably for pasty or fluid compounds, having a closure lid (14) which has an exit opening (22), and a closure pin (17) which is arranged in the closure (1) and closes the exit opening (22) from the inside, the closure pin (17) releasing the closure opening (22) because of an increase of pressure in the closure (1), using an elasticity inherent in the closure (1). In order also to achieve a simple construction with reliable functioning, the invention proposes that the closure (1) has a closure chamber (12), that the closure pin (17) with a pressure base (18) assigned to it is enclosed in the closure chamber (12) and that a through-flow opening (10) into the closure chamber (12) can be closed. <IMAGE>

Title: On-line deflection compensation in instruments which use focused beams
Inventor: STURM STEVE PERRY
IPC: G01D18/00
Filed: 1994-06-17
Abstract: A device having a focused light beam measures properties of webs of flat material. The device and a reference surface, a support frame in a carousel, are located on opposite sides of the web which is held at a fixed distance from the reference surface by a device for holding it down using the Bernoulli effect, so that changes in the gap influence the focus of the beam. The device and the reference surface scan the web using a scanning frame. The device is calibrated and standardised in a position without a web, a first surface, a support frame of the carousel, being moved in a position opposite the device and in the plane of the web. The device measures the first surface and a second surface, another support frame of the carousel, which is moved in a position opposite the device but further away or closer in comparison to the first surface. The distance of the device from the web is calculated from the distance between the measurements of the first and second surface. The calculated separation is used in order to define a working point on a device response curve, and the device is correspondingly calibrated. A polynomial of second or third order is fitted to the response curve of the device and differentiated at the working point on the curve, in order to determine the rate of change of the measurement properties of the device at this point. Variations in the gap and the defined rate of change of the ... Original abstract incomplete. <IMAGE>

Inventor: MORE ANTON DR
IPC: C21C5/56
Filed: 1994-08-20
Abstract: The invention concerns converters and a method of refining metal melts, in particular pig iron to steel, using a coutercurrent technique. The method is characterized in that converters are used which comprise at least two segments and a slag or mixture of slags is introduced into the last or at least the last but one segment of the oxygen converter, the slag having the following chemical composition after being heated to 900  DEG C: SiO2 + Al2O3 + TiO2 + FeO + MnO 1 to 70 wt.%, SiO2 0 to 15 wt.%, Al2O3 0 to 35 wt.%, Cr2O3 0 to 10 wt.%, TiO2 0 to 7 wt.%, FeO 0 to 70 wt.%, MnO 0 to 20 wt.%, CaO + MgO + CaF2 30 to 95 wt.%, MgO 0 to 15 wt.%, CaF2 0 to 10 wt.%, plus impurities. After melting and reacting with the iron melt and with the oxides arising from oxygen refining, the slag flows in the opposite direction to the iron. Between each of the converter segments is a partition with one or more overflows for the slag and one or more openings near the converter floor for the iron melt. If there are several partitions, i.e. with converters with more than two segments, a gradient exists for the flow of slag through the overflows in the opposite direction to the iron. On completion of the refining treatment, the iron melt preferably leaves the last segment of the converter through a siphon.

Title: Method of controlling and/or safeguarding the quality of concrete compaction in the manufacture of concrete bricks in concrete brick machines
Inventor: BALD HUBERT
IPC: B22C15/10
Filed: 1994-09-28
Abstract: Method of controlling and/or safeguarding the quality of the compaction of moulding masses to be shaped and compacted in moulding boxes under the action of compacting impacts. The quality evaluation is based on the knowledge that the quality achieved during a sample compacting operation under quite specific process conditions is achieved with good reproducibility, even with repeated compacting operations, when the quite specific process conditions of the sample compacting are fixed (see Fig. 1a) and are reproduced during the repeated compacting with only minor permitted deviations. Accurate observance of the specific process conditions can be guaranteed especially by regulating the quantities concerned. Application preferably in brick-moulding machines.
