Filed: 1981-12-10
Abstract: The invention relates to metallurgy and to the foundry field. The process comprises the treatment of molten crude iron, fed to a ladle, with a vacuum and modifying additives. The vacuum treatment of the melt is here carried out before the start of the interaction of the melt with the modifying additives and during this interaction, without interruption for 15 to 120 s. The equipment for carrying out the process according to the invention comprises a receiving vessel (1) with an outlet port (1b) closed by an insert (4), a ladle (2) arranged underneath the receiving vessel (1) and having a charging spigot (2a), and a vacuum chamber (3). The vacuum chamber (3) contains a branch (3a) for connecting the plant for evacuation of the air and is connected to the receiving vessel (1) and to the ladle (2) in such a way that a closed space, bounded by the walls of the vacuum chamber (3), is formed between these. The diameter of the outlet port (1b) is determined from the condition D = KV, where D is the diameter of the outlet port in mm, V is the volume of the melt to be treated in dm<3> and K is a proportionality factor amounting to 1.5 to 5. Modifications of the process and equipment are described. The process and equipment can be used for producing crude iron with a modified form of graphite - in the spheroidal form and vermiculite form. <IMAGE>

Title: Detachable solder connector for printed circuits
Inventor: HUCKENHOLZ OLAF
IPC: H05K1/02
Filed: 1982-02-17
Abstract: The assembled poles are supported resiliently in a common holder. In the clamped state, the individual poles attempt to release the solder point by their tension. For through-plated printed circuits, the ends of the poles may have a spherical or double-conical shape so that the hole, allocated to the pole, in the printed circuit is freed of solder in the same procedure during the desoldering process. The invention results in a cheap, operationally reliable solder connection which can be released using simple tools. No special measures are required for assembly, and fitment can be carried out automatically. <IMAGE>

Title: Instrument for measuring the density of liquids
Inventor: ALBER BERND DR
IPC: G01N9/18
Filed: 1982-03-24
Abstract: Instruments for measuring the density of liquids or the concentration of a plurality of components of a liquid have a completely enclosed hollow glass body, which is weighted at its lower end and is provided with a scale and is known under the designation areometer, is based on Archimedes's principle and has undergone no fundamental changes since the times of Archimedes. Measurements are very laborious, and as a result densities and concentrations on the laboratory and industrial scale have been determined in the meantime by other methods. In order to modernise the measurement of densities or concentrations on the basis of Archimedes's principle, a congeneric instrument is to be extended and automated, so that accurate and largely automatic measurements are possible. To this end provision is made to arrange in the hollow glass body (4) a magnetisable body (8) oriented perpendicularly to the extension direction of the hollow glass body, at least one electromagnet (14) being arranged around a container (3), the coils of which electromagnet furthermore, as a function of the submersion of the glass tube (4), can have a current applied to them by means of an electronic unit (23). <IMAGE>

Title: Device for continuous precipitation (cementation) of metals from their solutions
Inventor: MEGERLE FRIEDRICH
IPC: C22B3/02
Filed: 1982-08-21
Abstract: For continuous precipitation (cementation) of metals from their solutions, vibratory vessels with baffles arranged therein are used, by means of which the penetration and hence washing around of the granular precipitants by the flowing solution is effectively assisted both on entry into and on discharge from the vibratory vessel. Especially when fine-grained granules are used as the precipitant, however, granules may be discharged or the outlet orifice may be blocked. According to the invention, this is avoided when the outlet orifice (7) for the spent precipitant with solution and precipitated metal is located in the side wall of the vibratory vessel (1), and when a hold-back plate (10) taken upwards from the vessel bottom is provided between the outlet orifice (7) and the baffle (9) arranged upstream of the outlet orifice (7). <IMAGE>

Title: Corner reinforcement for plasters as well as process and apparatus for producing a corner reinforcement
Inventor: BISANG ROBERT
IPC: E04F13/06
Filed: 1983-02-01
Abstract: A corner reinforcement (1) (Fig. 1) comprises a flexible lattice fabric, which is attached as corner strips in the corner region of a wall. The corner reinforcement (1) has a predetermined bending zone (6), running in the longitudinal direction of the reinforcing strip (5). The strip (5) is of a flat form before attaching in the corner region of the wall and during attaching to the corner of the wall is bent off appropriately in the region of the predetermined bending zone. This can be performed with relatively low deforming resistance without further aids, by virtue of the increased bending readiness in the predetermined bending zone. The fabric is provided with a thermoplastic sheathing as a finish. The apparatus for producing such a corner reinforcement has at least one heating zone as well as a deforming device, by means of which a thermoplastic deformation in what is later the predetermined bending zone and, if appropriate, also a recovery into the flat form can take place. By virtue of the initially flat configuration of the corner reinforcement, it can be kept well in rolls in particular, in a virtually endless form. <IMAGE>

Patent DE-3315828-A1 (DE)
Title: Heating installation
Inventor: SEYER REINHARD DIPL ING
IPC: G05D23/19
Filed: 1983-04-30
Abstract: The invention relates to a heating installation which transports heat to consumers using the flow temperature and/or water throughflow. In central-heating systems it is known to control the flow temperature by means of an atmospheric sensor. It is also known to determine the desired value of the flow temperature from the difference between flow and return temperature. In both cases, the characteristics of the building must be worked out and supplied to the control system. The invention neither requires an atmospheric sensor, nor is an input of building-specific heating curves necessary; this is achieved according to the invention in that the heat supply provided is changed in such a way that it corresponds exactly to the value required by the consumer with the highest heat demand. Each consumer (5, 5', 5'') is assigned a device (7, 7', 7'') to determine the heat demand, which is fed to a central heating-regulating device (2) which determines the level of heat supply required from the demand information and changes the heating output (1, 3, 4) on the basis of the highest required heat demand (Figure). <IMAGE>
Patent DE-3316246-A1 (DE)
Title: Focus-correcting device for inclined projection in overhead projectors
Inventor: WIEDLING HARTMUT DR
IPC: G03B21/132
Filed: 1983-05-04
Abstract: Because of the normally upwardly sloping projection direction, the use of overhead projectors requires a projection plane (screen) which can be adjusted in inclination for a sharp projection of the entire written surface. In the case of inclined projection onto a perpendicular wall, by contrast, sharp projection of the entire written surface has so far not been possible. If, however, the written surface is provided with a slope, it thereby becomes possible for the entire written surface to be simultaneously sharply projected even in the case of inclined projection onto a perpendicular wall. A slope of less than 10 DEG  is sufficient for normal projection situations, that is to say a raising of the rear boundary of the written surface by a few centimetres. If, in addition to a device for inclining the written surface to the front, a possibility for a lateral inclination is provided, a projection which is sharp over the entire written surface is facilitated even in the case of projection directed obliquely to the side onto a perpendicular wall. The efficiency of an overhead projector can be substantially improved by means of such a device, which is to be realised in a technically very simple fashion.
