Patent DE-3102723-A1 (DE)
Title: Cross-flow heat exchanger
Inventor: KRUMMENACHER THEO
IPC: F28F19/04
Filed: 1981-01-28
Abstract: The subject matter of the invention is a cross-flow heat exchanger having a first exchange medium, e.g. fresh air to be heated up, which is guided between exchanger plates or inside tube bundles, and a heated, second exchanger medium, e.g. flue gas, which flows around the exchanger plates or tube bundles at right angles to the first working medium inside a sealed working chamber. The invention is characterised in that the contact surfaces in the working chamber of the second exchanger medium with the exchanger surfaces are lined with a plastic sheet. As a result, the service life of the surfaces with which the flue gas makes contact is substantially increased. Figure 6 shows the perspective side view of the part of a plate heat exchanger. The invention provides that the surfaces in the flow channel (43) which come into contact with the flue gas are lined with the previously mentioned thermoforming sheet (26). The thermoforming sheet (26) in this case coats the inner surfaces of the exchanger plates (37, 36) projecting into the flow channel (43). After the said individual plates have been coated, the seals (41, 42) are then attached, so that the thermoforming sheet is clamped between the seals (41, 42) and drawn up as far as the fresh-air side. The thermoforming sheet is thus fixed to the exchanger plates (33, 34) by the seals (41, 42). <IMAGE>

Patent DE-3110104-A1 (DE)
Title: Device for regulating liquid-discharge quantities
Inventor: GIEHL KLAUS-ULRICH DIPL ING
IPC: E03F7/00
Filed: 1981-03-16
Abstract: The invention according to the main patent DE-PS ... (Patent Application P 3007035.0-25) describes a device for regulating discharge quantities, comprising a float-controlled orifice plate which can be inserted, in particular, in stormwater-retention tanks in sewerage systems, where the accumulating sewage is to be stored and then passed on in a restricted manner to the sewage-treatment system. The invention according to the patent of addition is based on the fact that, first of all, a blockage of the residual-gap opening, occurring when the float is in its highest position, between the lower edge of the orifice plate and invert is prevented by two or more orifice plates being arranged with respect to one another. They function in the same manner as a screen. Secondly, in the case of relatively large accumulation depths, the form of the orifice plate is enlarged by a gusset plate such that said orifice plate, in its end position, constricts the residual-opening surface only laterally without falling below the minimum height of the residual-gap opening, as a result of which the risk of blockage is reduced and a better approximation of the actual discharge quantity to the desired discharge is ensured. The figure shows an exemplary embodiment according to the invention which shows the discharge regulator at the highest position of the float, there being provided, in front of the orifice plate (1), a second orifice plate (1') which protects the individual-gap opening (24) from blockage in the manner of a screen. <IMAGE>

Patent DE-3134577-A1 (DE)
Title: Electric cutting machine
Inventor: WERNER JOHANNES
IPC: B26D1/20
Filed: 1981-09-01
Abstract: An electric cutting machine for cutting flexible, flat sheets of material, especially sheets of paper or the like, contains a supporting table, a cutting edge on the supporting table and a revolving blade in a blade head, which blade interacts with the cutting edge, and which head is mounted above the cutting edge so as to be displaceable along a guide rail and is supported, together with a supporting roll which drives the revolving blade, on a lowerable holding-down device, in order to press a sheet of material against the supporting table during cutting. An electric drive motor drives the blade head via an endless pulling element to perform a cutting operation. In order to protect, in a simple fashion, the drive motor and the pulling element from preloads when the blade head is stopped abruptly, the pulling element takes the form of an endless belt which is fastened to the blade head by means of frictional engagement, so that when the blade head is braked abruptly, the endless belt slips further relative to the blade head, while rubbing against the latter, and finally comes to a stop.
Patent DE-3135801-A1 (DE)
Inventor: SCHIMMEL GUENTHER DIPL CHEM DR
IPC: C01B25/46
Filed: 1981-09-10
Abstract: The disclosure relates to a process for after-treating extraction residues, termed raffinates, originating from the extractive decontamination of crude phosphoric acid. To this end, the disclosure provides for the raffinates to be converted to two separate solid matter fractions of differant chemical composition by admixing the raffinates with a calcium compound so as to establish a pH-value of 1.2 up to 2.5. Next, the resulting precipitate consisting essentially of gypsum is filtered off as a first solid matter fraction, and washed with water. The resulting filtrate and the wash water are made into a mixture and predetermined proportions of calcium compound are added so as to obtain, after complete reaction, a fully reacted filter cake with a pH-value of 9 up to 12, the resulting suspension being filtered off at a pH-value of 6 to 8. The filter cake consisting essentially of calcium phosphate is separated as the second solid matter fraction, and allowed to react completely.

Patent DE-3143295-A1 (DE)
Title: Indicating instrument
Inventor: BOCK KARL
IPC: G01D11/02
Filed: 1981-10-31
Abstract: An indicating instrument with a fixed electrical coil (8) has a disc (5) which is rotationally rigidly connected to a pointer shaft (2) which carries a pointer (3). The disc (5) is connected by means of three tension wires (6) to the bearing shield (1) through which the pointer shaft (2) is rotatably carried. A spiral spring (11) is capable of twisting the tension wires (6) by rotation of the pointer shaft (2) and thus of attracting the disc (5). Magnetic forces pull the disc (5) in the opposite direction. The coil (8) is designed in such a manner that the measurement current reinforces or weakens the magnetic forces so that, as a result, the disc (5) approaches or moves away from the coil (8) whilst rotating. This rotation is transferred to the pointer (3) via the pointer shaft (2). <IMAGE>
Patent DE-3143937-A1 (DE)
Title: Conveyor having a rotating band (belt)
Inventor: GERLACH GUENTER
IPC: B65G23/44
Filed: 1981-11-05
Abstract: In conveyor bands, especially those with a relatively large width of the belt, there is the danger of transverse displacement of the belt (slanted running). To prevent this danger, in the present case one of the deflecting rollers or drums for the belt is made movable, specifically especially tiltable. As a result of appropriate (tilting) movements of the belt drum, triggered by a band-monitoring device, deviations from an exact band run are compensated. <IMAGE>

Title: Go-devil for lining pipes
Inventor: BOER HUBERT
IPC: B05C7/08
Filed: 1981-11-30
Abstract: The invention relates to a go-devil for lining pipes with an inner coating and relates to a go-devil with guide bodies which have U-shaped guide elements which rest against the pipe wall and whose front U-legs are non-displaceable and whose rear U-legs are mounted in the go-devil so as to be displaceable in the axial direction and are attached to a common bearing. In order to permit lining of pipes with fluctuating inner diameters, according to the invention an extraction body, which is elastically extendable in the radial direction and has an axial bore and a conical pressure body which engages in the bore and is mounted in an axially displaceable fashion in the go-devil, is arranged behind the rear guide body. The pressure body is connected to the axially displaceable bearing in the guide body by means of a tensile and pressure element in such a way that the elastically extendable extraction body is relieved of tension in the rearmost position of the pressure body and during its axial forwards movement is elastically extended with a concomitant increase of its diameter. The diameter of the bore and of the angle of inclination of the pressure body are dimensioned in such a way that the changes in the diameter of the extraction body correspond essentially to the changes to the diameter of the guide body.

Patent DE-3218241-A1 (DE)
Title: Device for centring spectacle lenses
IPC: B24B13/005
Filed: 1982-05-14
Abstract: The invention relates to a device for centring spectacle lenses and fastening a retaining part to the lenses according to patent application P 3150967.3, having a base frame, a perpendicular guide column (11) arranged thereon, and a height-adjustable and rotatable sleeve (24), which has a right angled slot (25) to which the swivel arm (35) which carries the retaining part (36, 37) is connected, it being the case that during longitudinal movement with respect to the guide column (11) a torque is exerted on the sleeve (24), with the result that a perpendicular edge of the sleeve slot is guided without play on a radial pin (15), projecting into said slot, of the guide column (11). The aim of this is to employ simple means not only to achieve simplified lowering and mounting of the retaining part on the spectacle lens, but also to ensure that the retaining part is lowered at an adjustable speed that is independent of the subjective force of the operating person and dependent on the type and thickness of the spectacle lenses, and to ensure a driving force on the spectacle lens. This is achieved by an external bush (54), which is driven in a rotatable fashion by a motor and has a slot (57) wound in the shape of a screw in which a radially outwardly directed pin (53) of the sleeve (24) engages. <IMAGE>
