Title: Device for metering and/or mixing dental materials
Inventor: GUNDLACH H-W DR ING
IPC: A61C9/00
Filed: 1993-03-29
Abstract: Devices for metering and/or mixing dental materials must be designed such that exact metering and mixing according to a predetermined formulation are possible. In the conventional devices, changes in viscosity or viscosity fluctuations result in metering errors and hence mixing errors. The invention is to permit exact metering and mixing independently of the viscosity and of viscosity fluctuations. In the device according to the invention the flow of dental materials is restricted. For this purpose, an outflow head (22, 43) is preferably assigned an adjustable flow restrictor (28, 29, 42) as a result of which inaccuracies in the transport of the dental materials are compensated. The device according to the invention is especially suitable for mixing individual components for the formation of multicomponent duplicating compositions based on silicone. <IMAGE>

Title: Process for the disposal of brominated chlorofluoro hydrocarbons
Inventor: SCHLUETER KLAUS DR ING
IPC: A62D3/34
Filed: 1993-06-01
Abstract: CFCs, in particular brominated CFCs, the so-called halones, can be reacted in alkaline medium under comparatively mild subcritical conditions. Salts with the cation of the alkaline solution are formed as harmless final products from the halones, which badly destroy the ozone layer. Laboratory experiments have shown that the main part of the reaction takes place in the first minutes. In this case, as a result of the subcritical conditions it is advantageous to the process presented here that according to it the wall thicknesses of the high-pressure apparatus can be made relatively thin. In addition, halohydric acids, whose corrosive attack on the high-pressure apparatus could not be controlled, are not formed in the two-phase region. On the basis of the knowledge obtained on the laboratory scale, a plant concept is drawn up and described with whose aid halones and other CFCs can be disposed of completely continuously in an environmentally protective manner.

Title: Set of playing cards
Inventor: KNIEP HERBERT
IPC: A63F1/02
Filed: 1993-06-23
Abstract: The set of playing cards described contains a first and a second set of playing cards, e.g. made of cardboard or plastic. In the case of the playing cards of the first set (I), on each longitudinal side (1) in the region of their ends, there is in each case provided a curved projection (3) formed on in the sheet plane, while the playing cards of the second set (II) have, on each longitudinal side (1) in their middle, in each case a curved projection (4) formed on in the sheet plane. The curved projections (3, 4) are shaped in such a manner that, in relation to the central longitudinal axis of the playing cards, they are congruent in a mirror-inverted manner. The curved projections are preferably of flat elliptical shape. These curved projections serve the purpose of facilitating sorting out of the playing cards when they have been mixed together. For sorting out, the card stack is taken hold of on the longitudinal sides with both hands in each case with thumb and index finger, and in particular firstly at the end curved projections and secondly at the central curved projections. By moving the hands in opposite directions, all cards with the central curved projections (4) are displaced in relation to the cards with the end curved projections (3). Then the two sets (I and II) can be separated from one another with one grip. <IMAGE>

IPC: B23K26/34
Filed: 1993-10-08
Abstract: The invention relates to a process for alloying a workpiece using a laser beam, carbon essentially being used as alloying element. According to the invention, an organic, combustible gas or gas mixture is burnt, the alloy coating is formed on the workpiece surface by adsorption of the carbon particles produced during the combustion, the carbon is fed at least partly into the molten mass produced by the laser beam and the workpiece is thus alloyed at the coated locations irradiated by the laser. The combustion flame of the fuel gas or fuel-gas mixture is advantageously directed by means of a burner onto the surface to be coated. Acetylene is preferably used as the organic fuel gas. The fuel-gas mixture, apart from the organic fuel gas, advantageously receives a gas containing oxygen, such as air, air enriched with oxygen, or pure oxygen. <IMAGE>

Title: Composting organic waste with full use of reactor vol. - involves adding further layers of material during or after turning to restore depth of material in reactor to initial level
Inventor: FRESENIUS JUERGEN DIPL ING
IPC: C05F17/02
Filed: 1993-10-15
Abstract: Organic waste (3) is composted in moist aerated linear reactors (2) in which the compost is placed in layers and is continuously turned over. In order to compensate for the shrinkage of the composting material during the composting process, additional layers of material are added during or after the turning process to restore the depth of the material in the reactor to its initial level. Also claimed is a turning mechanism (1) for carrying out this procedure, consisting of a vertically arranged full-width conveyor with an endless scraping and conveying belt whose upper section conveys the compost backwards and deposits it behind the conveyor. The innovation is that the motion of the belt (1) is reversible and the conveyor is open at both ends. USE/ADVANTAGE - In composting organic waste. The reduction in compost volume during rotting is evenly distributed throughout the reactor, and full use of the reactor volume is ensured.

Abstract: PCT No. PCT/DE94/01311 Sec. 371 Date May 9, 1996 Sec. 102(e) Date May 9, 1996 PCT Filed Nov. 7, 1994 PCT Pub. No. WO95/13532 PCT Pub. Date May 18, 1995The invention relates to a measuring process for the indirect measurement of the temperature and solids content of metal workpieces during inductive heating. To this end, in a coupled coil system comprising a heating coil, the effect of alterations in the electrical conductivity of the workpiece is determined by the combination, using circuit-mathematical techniques, of a signal tapped from the exploring coil with a reference signal from the driving coil. The two signals are combined in such a way that the measurement signal obtained depends solely on the phase shift between the reference signal and the exploring coil signal and/or on the quotient of the amplitude values of the reference signal and the exploring coil signal. This facilitates measurement which is independent of the amplitude of the alternating electromagnetic field created by the driving coil. With the aid of alloy- and geometry-specific calibration curves, the measurement signal can be associated with the particular value being sought (temperature or solids content). In addition, the measurement signal can be used for the continual adjustment of the heating in order to regulate the target value.

Patent DE-4406924-A1 (DE)
Inventor: HELLER HANS DR
IPC: G06F11/14
Filed: 1994-02-28
Abstract: In the system proposed, each computer (RS1 to RS3) carries out a control function based on the concept of the finite-state machine. For data-transmission purposes, each computer (RS1) is linked to every other computer (RS2, RS3). The computers can only become effective in controlling the process when they receive a circulating token. The reception of inputs causes the processing of transactions in which new internal statuses and output symbols are produced from existing internal statuses and input symbols. The transactions which are completed or interrupted the next time the token is received are subsequently checked to determine whether the status values used collide with alteration messages relating to the status of the system and transmitted, together with the token, to the computer concerned. The completed transactions are either approved for execution or rejected as a result of this check. For processing extremely time-consuming transactions, special criteria apply. The method proposed is particularly suitable for data-processing systems in which the individual computers operate essentially independently of each other and only occasionally access data from other computers. The method is intended for use in the field of railway signalling.
