Title: Pattern tree for the formation of a casting mould producible by the lost-wax method
Inventor: SCHUESSLER BERND
IPC: B22D25/02
Filed: 1984-05-02
Abstract: A pattern tree for the formation of a casting mould producible by the lost-wax method is made up of mould parts which can be assembled as a kit and are composed of wax or plastic which can be melted out, the mould parts consisting of modules which comprise one or more patterns each with an individual sprue and part of the common sprue. These modules can be plugged in and locked via a support seated centrally in the base, which can likewise be melted out, the sprue parts of the individual wax patterns being inserted one above the other and forming the common sprue of the pattern tree. This assembly kit technique leads to considerable savings in the construction of the pattern tree and also in the further stages of the lost-wax process.

Abstract: The invention relates to a device for dedusting the exhaust gases from internal combustion engines and internal combustion systems, at least one emission electrode (2) and, on each side thereof, in each case one electron collector (3, 4) being arranged for the dedusting. In order always to keep the efficiency of the device at the same level, in particular in order always to obtain the same amount of precipitated dust between an emission electrode (2) and an electron collector (3, 4) and, in addition, to be able to precipitate dust particles smaller than 1  mu m in size, the electron collectors (3 and 4) are constructed as movable continuous belts with brush-like surfaces (3B, 4B). Each continuous belt is guided via two rollers (3W, 4W) so that it is possible to move the continuous belt continuously onwards. If a dust layer has been formed in the surface of an electron collector (3, 4), the continuous belt is moved, by turning the rollers (3W, 4W), into an area which is located below the baseplate (5) of the device. Here, devices for cleaning the brush-like surfaces (3B, 4B) are provided. The cleaned belt element can be subsequently moved back upwards into the area of the emission electrode (2) and again used to precipitate dust (20). <IMAGE>

Patent DE-3509349-A1 (DE)
Title: Heat exchanger for heaters
Inventor: GALTZ RUEDIGER
IPC: F28D21/00
Filed: 1985-03-15
Abstract: According to the invention, an improved heat exchanger is specified which is intended, in particular, for heaters, such as auxiliary heaters. In order to avoid heat accumulation and temperature peaks on the base region of the heat exchanger, on the inner surface of which the flue gases emerging from the combustion chamber of the heater reverse their flow direction, solid longitudinal ribs are integrally formed on the wave crests of the corrugated casing. In the region of the wave crests and/or wave troughs formed by the corrugated casing, sites are provided where the cross-section is thickened and which, especially in conjunction with the integrally formed longitudinal ribs, permit the dissipation of heat from the critical base region of the heat exchanger to its cooler flanged side. The integrally formed longitudinal ribs can have different dimensions in the radial direction, and it is also possible to provide a plurality of longitudinal ribs on one wave crest which preferably branch out in the manner of a fork. The heat exchanger is preferably constructed as a casting in such a way that it can be removed from the mould in a pulling direction. The thermal loading capacity can be increased due to the dissipation of heat from the base region of the heat exchanger in the direction towards its flanged side, and a more efficiently operating heat exchanger is obtained.

Title: Process for the recovery of products of evaporation and thermal secondary treatment in simultaneous SO2 and NOx gas purification
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-08-03
Abstract: The main application P 3519681.5 relates to a scrubbing water treatment with recovery of valuable materials and waste water evaporation. The waste water is first passed into an H4EDTA precipitation stage and H4EDTA is precipitated by mineral acid. After the filtration, the filtrate still contains sodium sulphate and nitrogen-sulphur compounds, which predominantly occur as amidosulphuric acid. This acidic filtrate is fed in its original state or after neutralization to an evaporation unit or spray-drier unit and the solid residue is given a thermal secondary treatment, after which a utilizable end product of predominantly sodium sulphate is produced. It has now been found that the recovery of the evaporation product can be improved according to the invention by evaporating or spray-drying the filtrate of the H4EDTA precipitation stage (1) with formation of Na2SO4 (3) in a unit (2), returning the Na2SO4 to the scrubbing circulation (8) for formation of NaOH and CaSO4, giving the residual product (4) of the evaporation or spray-drying a thermal secondary treatment in a unit (5), gaseous products (7) being conducted into the flue gas path (9) and being converted in the flue gas purification to CaSO4 and by the remaining residual product of the evaporation being Na2SO4 (6) and being returned to the scrubbing circulation (8). <IMAGE>

Patent DE-3543200-A1 (DE)
Title: Flat-cable connector
Inventor: HARTWIG KLAUS
IPC: H01R4/24
Filed: 1985-12-06
Abstract: The flat-cable connector contains insulation-piercing terminal contacts having two limbs which have tips and bound a slot between them. These limbs are pushed into the insulation of a flat cable and are mechanically held therein. At the same time, they touch the metallic conductor and make electrical contact therewith. In consequence, the flat cable can be connected to other cables or to a printed-circuit board. According to the invention, the mechanical retention of the limbs which are pushed into the insulation is intended to be increased. For this purpose, a web is integrally formed on the insulation-piercing terminal contact. A tab originates from said web. While the limbs are pressed into the insulation of the flat cable from underneath, the tab is pressed onto the cable from above. In consequence, said cable is clamped inbetween the limbs and the tab. This leads to a mechanical connection, which cannot become detached even in the case of vibration, between the insulation-piercing terminal contact and the flat cable.

Title: Method and device for systematic deflection of light
Inventor: HIPP JOHANN F DIPL PHYS
IPC: G01S7/481
Filed: 1985-12-11
Abstract: In order to deflect light systematically, divergent light sources are converted into line-like sources. Plane plates which can be rotated in the divergent beam path are used to produce a beam offset which causes a deflection of the light bundles behind a projection lens. The angle of rotation of the deflecting element is measured as a measure of the deflection. The combination of two deflecting subassemblies aligned vertically relative to one another renders possible a device by means of which each point can be measured within a limited solid angle.
