Patent DE-3034802-A1 (DE)
Title: Foamed medium application - uses suction to draw foam through screen onto the fabric
Inventor: MITTER MATHIAS
IPC: B41F15/40
Filed: 1980-09-16
Abstract: The foamed medium is contained in a zone above the screen, and is drawn into the fabric by suction, without pressure on the medium. After the suction point, there can be a mechanical pressure or scraper action on the foamed surface. The screen or intermediate screen carrier (4) on the fabric (1) is a perforated plate, a grid, netting, woven wire material, a screen drum or stencil, moving either with the fabric or travelling independently. The tubular medium feed (2) is located above the screen (4), for the foam to be held (50) without pressure. A pressure cloth (3) is placed under the fabric (1) but above the suction unit (6) to act as a permeable fabric carrier. The applicator roller or scraper lies after the suction unit in the direction of fabric travel. The medium feed (2) is controlled to deliver foam according to the rate of foam consumption, using an adjustable level indicator (7) connected to a supply pump. A variable vacuum pump (60) gives an adjustable rate of suction (6) to draw the foam through the fabric, according to the volume of foam in the holding zone (50). The screen (4) is a continuous web. The various process parameters are monitored for use by a computer with digital display for process control. The process gives a constant and controlled application of foamed dyestuff, as the bubbles break up on the screen instead of on the fabric surface, and fluid inconsistencies are eliminated.

Patent DE-3042650-A1 (DE)
Inventor: FINK PETER A DR
IPC: G12B11/02
Filed: 1980-11-12
Abstract: In this method, a coating is applied to a substrate, e.g. glass, and then a laser or electron beam (13) is used to produce markings by local evaporation of the coating (16). Since, by contrast with scribing/scoring of a coating, no chips occur, very clean markings are produced. The device has a stabbing motor (19) by means of which the carriage (17) is displaced from marking to marking by a recirculating ball screw (21). The laser (11) produces on the coating (16) by means of the collimating lens (25), the cylindrical lens (27), the mirror (29) and the focusing lens (31) an area illuminated in the form of lines, the temperature in the region of this area being so high that the coating material is vaporised and a line is produced. <IMAGE>

Title: Bearing for a rotary-wing aircraft
Inventor: ROMAN STEPHAN
IPC: B64C27/33
Filed: 1981-02-10
Abstract: The invention makes available an assembled helicopter rotor system which has no bearing and in which an individual or single and only flexible strip is used as at least the main wing support and which furthermore preferably has a wing tilting shaft. The line of the shear centres of the flexible strip, the line of the shear centres of the wing tilting shaft and the tilting axis each lie somewhere along a straight line or they run essentially in a straight line. The special cross-sectional shape of the construction which comprises the flexible strip is preferably a construction in the case of which two limbs, which spread apart from one another from a central gap located between them, form the leading edge with respect to the rotation direction, and these limbs run in a gradually curved manner backwards so that they go backwards parallel to one another, a transverse web extending between them at a point which is to some extent in their rearward half. In such a configuration, the line of the shear centres of the flexible strip is located at a specific point behind the web, and this also applies to the wing tilting shaft which may be a solid rod of circular cross-section whose line of shear centres is located in the centre. In this case, the line of shear centres is located on the same straight line to the rear of the larger part of the flexible strip or of the entire flexible strip, and the tilting axis of the wing, which is arranged further outwards in this identical wing arrangement, is likewise located on this same straight line. A different design, which is specifically generally to be preferred, is a design in the case of which the cross-section has the form of an I whose web is located in the longitudinal direction with respect to the rotation, the head of the I additionally running over a greater length than its foot. The web has a large intermediate position, of cup-shaped cross-section, in which the wing tilting shaft is located. In other forms of the construction, the flexible strip leads the wing tilting shaft. One of these forms of construction of this type, which can be regarded as being more desirable than the others, has the cross-section of an elongated approximately rounded groove which is provided with lips, or of an elongated approximately rounded U-profile which is provided with lips, the side of which groove or U-profile which is opposite the opening provided with lips being arranged in the direction of the wing rotation. Other cross-sections, which are described for the flexible strip in the trailing position, comprise an elongated groove which is cut at right angles and is provided with lips, an elongated groove which is cut partially at right angles and is provided with lips, and a C, the opening pointing away from the rotation direction in every case, and a T, whose head is turned in the rotation direction, as well as a complicated modification of the elongated groove which is cut at right angles and is provided with lips, in the manner which can be seen, for example, in Fig. 12. <IMAGE>

Title: Process and device for mechanical/thermal treatment including sterilisation or pasteurisation of fluid masses
Inventor: SCHMITT ARMIN
IPC: A23G1/18
Filed: 1981-03-23
Abstract: The process and the device to carry it out continuously serve for the sterilisation of liquid to pasty masses, in particular cocoa masses. According to the invention, the continuously deacidified, partially dehydrated and degased mass is dammed in the course of its continuous transport and a temperature of above 100 DEG C to approximately 150 DEG C, preferably 135 DEG C, for microbial destruction is generated in the dammed-up mass by internal friction. The microbial destruction temperature is held at its mean value during this by external heat supply or heat removal. Cooling below 100 DEG C is then carried out and a residual dehydration and degasing follows. Deacidification, dehydration and degasing are carried out in so-called thin-layer apparatuses (1, 2) and the microbial destruction is carried out in a back-up reactor (5). <IMAGE>

Title: Method for recording the torque and angle of rotation in impact screwdrivers
Inventor: MAYER EBERHARD DIPL ING DR
IPC: B25B23/147
Filed: 1981-07-18
Abstract: In a known method for recording the torque and angle of rotation in impact screwdrivers by means of a measuring arrangement which contains a progressive spring element, installed between the screwdriver and tool or in the tool itself, and an interrogation and evaluation unit, the first torque increase usually prevents an accurate recording of the actual torque as a function of the angle of rotation. In order to eliminate this shortcoming, it is proposed, according to the invention, to measure continuously the respective duration of the impact pulses which decreases with an increasing torque, to compare it with a predetermined minimum pulse duration assigned to the desired final torque and to switch off the impact screwdriver when an impact-pulse duration corresponding to this minimum pulse duration is reached. <IMAGE>
