Title: Baking of porous or carbonaceous ceramic prods. - where gases evolved by prods. during baking are completely burned in furnace so no toxic gases are discharged into the environment
Inventor: HAESSLER ANDREAS ING GRAD
IPC: F27B13/02
Filed: 1980-11-05
Abstract: The prods. are fed into a continuous furnace, and when they are heated they evolve toxic and ignitable gases. The gases are drawn by suction out of a furnace chamber in which the prods. are being heated, and are fed into other furnace chambers in which the prods. are being cooled. Only waste gases leaving the hottest furnace chamber are fed to an exhaust gas chimney which discharges the gases into the environment. Before entering the chimney, the waste gases are pref. fed through a heat exchanger. Used e.g. in mfg. lightweight bricks or lightweight refractory blocks, where carbonaceous matter in the bricks is burnt during baking to form pores in the prods. Elimination of environmental pollution which would occur if partly burnt gases were released to atmos. In the invention, the gases liberated by the bricks etc. are completely burnt before reaching the atmos.

Inventor: DANGELMAIER BERNHARD
IPC: B29C45/27
Filed: 1980-12-10
Abstract: A nozzle core forming part of a hot duct injection nozzle for a plastics injection moulding machine has a tapering forward end comprising outlet openings and fitting into the nose of the nozzle casing, while the rear end of the core is seated in a cover at the rear of the nozzle casing. The core is thus firmly clamped between these two end supports of the casing and cover. Around the core an annular space contains a helically wound electrical resistance heater, snugly fitting into a helical groove in the outer, cylindrical face of the core, while there is a cylindrical (annular) air gap outside this heating element. The electrical supply lines pass out radially through a duct in the casing. A good fit between the electrical heating element and the outer face of the core is obtd., resulting in good heat transfer. The heat transfer obtd. is greatly superior to that achieved in a previous design in which the electrical element lies in ducts of considerably larger dia. within the core piece.

Title: Magnetic layer-thickness meter in pencil form
Inventor: NIX HANS F ING GRAD
IPC: G01B7/06
Filed: 1981-05-26
Abstract: The invention relates to a magnetic layer-thickness meter in pencil form, which is used to measure the thickness of non-magnetic layers (2) on ferromagnetic substrates (3) using the principle of adhesive force. A permanent magnet (4) is suspended from a measuring spring (6) which is connected to a slide (10) at the end opposite the magnetic clamp (4). The slide is guided to move axially on the outside of the housing of the measuring instrument. During the measurement operation, the end of the magnetic clamp (4) is in contact through the open end of the housing (5) with a non-magnetic coating on a ferromagnetic substrate (3), so that the layer thickness of the coating is measured as a function of the adhesive force of the magnet (4) when the latter is raised from the coating by the upwards movement of the slide (10). The measured layer thickness of the coating can be read off on a measuring scale (9) which extends along the housing (5). The slide (10) can be provided with inner elastic friction rings (15, 15a) or with an inner, rotatable friction element (26), in order to avoid inadvertent movement of the slide. In addition, it is possible to provide in the housing (5) a stop sleeve (27) which prevents the magnetic clamp (4), when the latter is raised from the measurement surface, from compressing the measuring spring (6) and displacing the slide (10). Different types of read-off devices can be provided on the slide (10) for the measured values of the layer thickness, and facilitate the reading off of the measuring scale (9). <IMAGE>

Title: Procedure for the automatic follow-up of a welding torch
Inventor: SCHULZE KLAUS RAINER DR RER NA
IPC: B23K37/02
Filed: 1981-07-13
Abstract: The invention relates to a procedure for the automatic follow-up of a welding torch along a weld fillet or weld seam during the fabrication of multi-layer welds or weaving welds with the use of distance sensors. By means of the invention, automatic positioning of a welding head is to be made possible for each weld seam of a multi-layer weld and a weaving movement is to be produced and tracked in accordance with the respective weld width. The invention is characterised in that the distance of in each case one effective sensor pair from the component surfaces and/or component auxiliary surfaces is varied step-by-step or continuously or the geometric distance change is electronically simulated. This can be done by progressive arrangement of sensors which are switched on as required, by displaceably mounted sensors, for example by displacement by means of a four-bar chain, or by electrical addition of an auxiliary voltage to the analog signal of one or more sensors, and if need be by measures influencing the characteristics of the sensor. <IMAGE>

Title: Process and measures for initiating the crystallisation of supercooled melts
Inventor: BERGER WILFRIED DR
IPC: F28D20/02
Filed: 1982-01-28
Abstract: It is known that molten crystals, in particular hydrates, have a tendency to supercooling, that is the chemical substance still remains in the liquid state even below the actual melting temperature or the transition temperature. It is further known to use the heat taken up by the crystals during melting for energy storage. (Use of the enthalpy of fusion or latent heat.) Heat stored in a latent manner can be kept for as long as desired without loss. The deliberate initiation of crystallisation and thus liberation of the heat is termed "retrieval". According to the invention, to the melt are added isotypic or epitaxial crystals, the melting point of which lies above the highest occurring temperature rise of the melt. The retrieval is carried out by cooling these crystals by external means until the desired crystallisation of the melt starts. From the crystal structure of the added foreign crystals, the formation of the "correct" crystals from the melt is then achieved.

Title: Magnetic generator for ignition systems of internal-combustion engines
Inventor: HIRT ADAM
IPC: F02P1/08
Filed: 1982-06-19
Abstract: A magnetic generator for ignition systems of internal-combustion engines is proposed, which ensures a contact-free ignition system, and additional loads, in a simple and cost-effective manner by utilising the magnetic energy in the rotating pole wheel as well as possible. In the case of this magnetic generator (10), the permanent magnets (12) of the pole wheel (11) which follow one another in the circumferential direction have equal pole widths (B), with the exception of two adjacent permanent magnets (12a, 12b). One of the two adjacent permanent magnets (12a, 12b) has a larger pole width and the other a smaller pole width and, in addition, the two pole shoes (18a, 18b) of the ignition armature (14) have a different pole shoe width. The ignition armature (14) is arranged inside the pole wheel (11) in a very small space. The remaining space in the pole wheel is used for the arrangement of further windings. The magnetic generator can be used cost-effectively for internal-combustion engines having additional electrical loads, to be precise both in the case of stationary machines and in the case of motor vehicles or other apparatuses having internal-combustion engines. <IMAGE>
